Abstract
A pair of scales - local canal-based (or village-based) and basin-scale (or valley-wide) - is featured in the irrigation of the mountain landscapes of Latin America. These scales arose historically through the interplay of cultural images with the political ecologies of agrarian transformation. In the Cochabamba region of Bolivia, long the irrigated breadbasket of the south-central Andes, the Inca state (c. 1495-1539) imposed canal-based irrigation using a powerful concept of rotational sharing (suyu). Valley basins containing local irrigation were a part of the territorial web of Inca state geography known later as verticality. The Spanish empire in Andean South America (1539-1825) was predicated upon a valley-centric colonial geography. Colonial rescaling involved despoliation and usurpation of waterworks, legal actions, and struggles over environmental change. Influence of the two irrigation scales has persisted. Today canal-based irrigation is not a timeless relict of indigenous customs, pace many postcolonial projects. Rather its usefulness, and its remarkable reinvention as a cultural concept and environmental creation, are the products of major modifications. Dismantling of multi-scale linkages in irrigation has reduced indigenous or peasant cross-scale co-ordination. Local containment poses threats to the environmental and socio-economic sustainability of canal-based irrigation.

Planners, farmers and aid officials have relied primarily on a pair of mental pic- tures to guide the making of irrigation works. One image is focused on the orga- nization of water resources at the local scale. Local irrigation refers to community-based or village-based management, which often is coordinated along a main canal. Many local, canal-based irrigation works are called juntas, although such indigenous names as suyus and ceques are used avidly in western South America (Peru, Bolivia).

Zimmerer A pair of scales local canal-based (or village-based) and basin-scale (or valley-wide) is featured in the irrigation of the mountain landscapes of Latin America. These scales arose historically through the interplay of cultural images with the political ecologies of agrarian transformation. In the Cochabamba region of Bolivia, long the irrigated breadbasket of the south-central Andes, the Inca state (c. 14951539) imposed canal-based irrigation using a powerful concept of rotational sharing (suyu). Valley basins containing local irrigation were a part of the territorial web of Inca state geography known later as verticality.

During the past 1015 years the image of local canal- or commu- nity-based irrigation has been widely diffused, including in major irrigation areas such as the Guadalajara-Querétaro region of Mexico, the Colca valley region of Peru, and the Cochabamba region of Bolivia.1 Rights to canal-based irrigation are often managed by a community or water users' group, while the creation of water markets is increasingly common in these arrangements. A second mental picture is that of irrigated landscapes at the scale of the basin or valley bottom. Basin irrigation typically is based on the centralized con- trol of several primary canals that cover a larger area than single canal-based waterworks. The basin image, like that of local canal-based irrigation, has been used as a mental guide, although the actual forms of basin irrigation have usu- ally differed somewhat from the ideal type. Fee arrangements and water mar- kets are typical of this type of irrigation. Development projects offering this style of irrigation warrant the labels of western, modern and global. The manage- ment of water resources at the scale of basins (and closely related units like sub- basins and multiple basins) has been characteristic of modern development in Latin America. Project sites for the basin-scale management of water resources include the GuadalajaraQuerétaro region of Mexico (for example, the Santiago and Autlan basins), the Colca valley region of Peru (the Majes sub-basin), and the Cochabamba region of Bolivia (the Central Valley basin).2 This study considers how local canal-based and valley-basin irrigation were shaped by the combined processes of social conflict and co-operation, political contestation and consolidation, and human environmental change. Irrigation geographies are taken to comprise both cultural pictures and material ecologi- cal and social constructs. Of special interest is how interconnected mental and socio-environmental processes have produced the distinct scaling of irrigation. I focus on the making of irrigated landscapes in the Andean countries of west- ern South America during the rule of this world region by paramount world powers, with special reference to the Inca state (c. 14001532) and the early Spanish colonial empire (15321650). I argue that a multi-faceted series of strug- gles and temporary resolutions led to the rescaling of irrigation between the 1400s and the 1600s. At that time the twin images of irrigation local canal- based and basin scale acquired an influence that has persisted with modifica- tion until today. The location of my case study of irrigated landscapes and scale is the greater Cochabamba region of central Bolivia (Figure 1). This so-called 'heartland' of Bolivia is a tropical highland region of the Andes mountains that occupies inter- mediate elevations between the westerly high Altiplano and the Andean pied- mont and Amazon lowlands to the east. The environments of central Bolivia and the Cochabamba region consist of scattered mountain basins at 20003000 m. and extensive upland settings. Long one of the most irrigated regions of South America, Cochabamba served under the Inca state and then the early Spanish colonial empire as the famed bread-basket of the south-central Andes. During these periods the irrigators and administrative rulers drew on a variety of men- tal images, ecological functions, and social organizations. Among the scales of irrigation the most salient were the local canal-based scale and the scale of the Rescaling irrigation in Latin America 151 Ecumene 2000 7 (2) valley basin. As will be seen, the past scaling of irrigation under the Inca and early Spanish world powers has been taken up in subsequent designs for irri- gated agriculture and, most recently, in its joining with environmental conser- vation. Geographical scale and political ecology The theme of scale is crucial to my study. I reject the a priori distinctions of canal-based irrigation as purely local and basin-style irrigation as purely global. Rather than a simple and fixed dichotomy of localglobal, the making of irri- gation is expected to involve a variety of key pheonomena social actors and practices, cultural ideas, political processes, environmental factors and flows that take place at several scales. Equally important, the relations of these causative phenomena across scales suggest the linkages of different identifiable scales. This insight, presented in the second section, leads my case study to scale up and scale down in order to comprehend more fully the making of local canal- based waterworks as well as basin-style irrigation. A political ecology perspective on scale refers to the interface of human activ- 152 Karl S.

Bañados del Izozog Central Valley ities and the environment. Geographical political ecology focuses on socio- natural scaling which occurs in the fusing of biogeophysical processes with broadly social ones.3 I find that many 'localglobal' studies tend to overlook the conditioning of scale by geographical cultural ecology. Yet concrete expressions of the human environment interface such as irrigation are definitely moulded by human-shaped biogeophysical factors and flows. (Biogeophysical processes vary from the directly human-induced to ones that are slightly or indirectly altered by people.) This recognition leads my case study to incorporate those environmental changes and biogeophysical factors including hydrologic, sediment, and vegetation processes that have affected people's rescaling of irrigation in Latin America. Emphasis on the making of scale suggests that the irrigated landscape should be thought of as the product of both environmental and broadly social processes that include the making of cultural images. A primary significance of this study is its focus on the environmental politics and political struggles that surround the practice of irrigation development. Increasingly, the modern western style of irrigation development is held to be culturally inappropriate, socially unjust and environmentally unsound.4 In response, local canal-based irrigation has emerged as a main alternative that is vigorously espoused by several hundreds of institutions throughout Latin America and in many developing countries worldwide.5 'Grassroots', 'local' and 'sustainable development', now being undertaken by these government agen- cies and nongovernmental organizations (NGOs), are planning a marriage of local canal-based irrigation and environmental conservation, with socioeco- nomic success. Scale is central to their claims, since local irrigation tends to be taken as an inherited relict that brings sufficient benefits to both the environ- ment and the people that irrigate. My findings challenge this assumption of the inherent character and viability of local scale irrigation. Rather, I show that local-scale irrigation is steeped in the selective adoption and alteration (together referred to as reinvention) of his- torical customs and traditions of resource use. In the Andean countries these formative historical geographies date to the Inca state and the early Spanish colonial empire. As will be seen, the local scale of canal-based irrigation has always depended on key linkages or articulations to processes that are differ- ently scaled. Several such processes, both broadly social and environmental, have typically tied local irrigation to basin-scale processes. These twin images should therefore be seen as contrasts that frequently are interlinked. This study is guided by ideas of scale that merge the perspectives of 'localglobal' processes and geographical political ecology. The perspective on scales of 'localglobal' processes (or 'glocalization') is concerned with the process-based scaling of sociospatial transformations that are part of so-called globalization.6 Those processes taking place at the large extra-regional scales referred to as global are typically associated with other processes that are scaled over smaller areas and that are referred to as local. Though the popular yet mis- guided notion of a rigid dualism of 'localglobal' scales prompts the call for rejection of the term, my study adopts it, along with the use of quotations. Here 'localglobal' and 'glocalization' indicate the reference to a geographical Rescaling irrigation in Latin America 153 Ecumene 2000 7 (2) approach that is focused on sociospatial processes and multiple-level scaling. Geographical political ecology is an approach or area of inquiry with a major interest in scale concepts. This approach shows general similaraities to the sub- fields of cultural and human ecology as well as hazards, geoarcheology, and land use.7 A dialogue between geographical political ecology and the 'localglobal' perspective on scale and scaling processes should avoid the one-way exchange of ideas. Indeed whole-cloth importations tend to preclude the weaving or con- necting together of ideas and concepts. Rather, I wish to advance an exchange of ideas between a scale-sensitive 'localglobal' perspective and geographical political ecology. The first exchange stems from the 'localglobal' perspective on scaling and territorializing. Scaling processes gain salience as people and institutions orga- nize their capabilities through social power, conflict, and co-operation . The pre- sent study shows how the scaling (or rescaling) of irrigation has depended on the 'scale capabilities' of social actors (such as Inca subjects, the Inca state and its provincial rulers, colonial Indians, Spanish colonists, and the Spanish colo- nial administrators). Of equal importance is the scaling of the biogeophysical irrigation environments. Indeed, differently scaled hydrologic, sediment, and vegetation processes tended to aid, or be exploited by, diverse groups or indi- vidual irrigators. Given these relations, the crucial scaling of the biogeophysical processes of irrigation should be interwoven with the account of social forces. A second exchange rests on the fuller awareness that the dynamism of 'localglobal' processes was common during European colonialism and even operated in various places during the periods of powerful pre-European states.8 'Localglobal' interactions under the rule of colonial empires and pre-European states periodically invoked the so-called cultural reinvention of traditions and customs.9 Reinventions were used by the rulers and subjects of the new societies as they sought to establish or resist new relations of social power, to give the appearance of social cohesion or identity, and to create legitimacy for new insti- tutions and status identities. Cultural reinvention, as a conspicuous feature of 'localglobal' processes, may be similarly common in the realm of humanenvi- ronment relations.10 Indeed, reinventions of the image of irrigation (and espe- cially its scale associations) were defining features of rule by the Inca state and the early Spanish colonial empire. Adjustments of irrigation ecologies coexisted with the rise of new cultural images. People's reworking of the ecologies of irrigation occurred through the alteration of biogeophysical factors and flows. Hydrologic, sediment and vege- tation processes became managed in different ways and acquired different scalar properties. As discussed below, these socio-environcultural processes were inte- grated under Inca rulers into a geographically extended and nested-type model of territory and land use. By contrast, the Spanish colonial rulers sought to con- solidate the management of environcultural processes in particular geographi- cal areas, particularly the valley basins. These altered ecologies, and their allied geographies, cooccurred alongside the metaphorical and cultural transforma- tions of irrigation. In a broad sense, the colonial Spanish ecologies were insep- arable from the reinvented images of irrigation, although to be sure the changes 154 Karl S. Zimmerer Ecumene 2000 7 (2) did not always occur in simple tandem, since the spacetime parameters of these processes were complex. Trenchant critiques of the approaches of 'local,' 'grassroots', and 'sustainable development' also urge a dialogue between the 'localglobal' perspective and geographical political ecology. The 'green lens' of these projects, as Zerner calls their environcultural emphasis, has tended to assume an overarching stability of the processes that are viewed as the foundations of community resource man- agement.11 Zerner and others use this insight to critique the frequent failure of community-based conservation that purports to make use of customary law. Their studies point out that misplaced or ill-founded assumptions of stability also apply to alleged spatial fixity, including the crucial elements of territory and scale.12 By adhering to preconceived ideas of ecological nature that bolster a claim to the spatial and temporal stability of resources, many projects can easily damage people and environments that are in or near management areas.13 The actual making of local, canal-based irrigation, as shown in the case study below, has been spatially dynamic and historically fluid. Periodic rescaling of local canal-based irrigation was produced by social contestations and coopera- tion. Change and alteration of biogeophysical factors and flows were also facets of rescaling. Modified hydrologic, sediment and vegetation processes acted both alone and in close concert with sociospatial changes to remake what constituted the 'local' of irrigation. Here I believe a policy message must caution against the prevalent notion, grounded in mistaken assumptions of stability, that local irrigation tends to be relatively timeless and independent of differently scaled processes. Irrigation and the Cochabamba region: suyu and basin definitions The making of past irrigation landscapes in Cochabamba cannot be separated from current dilemmas. At present the greater Cochabamba region of central Bolivia, as shown in the inset of Figure 1, is home to about 2 million people. The majority of inhabitants are rural and semi-urban farmers and livestock- raisers who work part-time, usually seasonally, in jobs in agro-industry and in the vast informal sector of the Cochabamba urban area (1990 population c. 900 000).14 Many people of Cochabamba speak Quechua as well as Spanish while some also rely on the Aymara language. Cultural and livelihood practices of the region's cochabambinos are hybrid concoctions of diverse expressions. Large numbers of people reside partly in Indian or peasant communities, while they may also work for extended intervals in modern cities such as Cochabamba or Santa Cruz, or foreign ones, including Buenos Aires and several in the United States. Poverty and the lack of basic requirements are commonplace in Cochabamba; living and working conditions are extremely difficult for the huge majority of the population. Irrigation-based agricultural development has been seized upon since the mid- twentieth century as a main solution to poverty in Cochabamba. Since then a large number of development agencies of international, national, and regional Rescaling irrigation in Latin America 155 Ecumene 2000 7 (2) governments have supported irrigation projects in the region. Neoliberal gov- ernment cutbacks, decentralization policies, and worsening poverty since 1985 have spurred more than 200 nongovernmental organizations (NGOs) to under- take projects in Cochabamba. Their recent projects tend to put a priority on the attempt to fuse development with environcultural conservation.15 Local-scale irrigation and environment-development objectives are nowadays a main com- ponent of many 'grassroots', 'local' and 'sustainable development' projects. Their interests in local canal-based irrigation are typically seen as supporting the postcolonial alternatives of community autonomy and govern cultural decen- tralization while opposing private interests and centralized state power. Projects with these interests have become locally common in Cochabamba and elsewhere in the Andean countries in the 1980s and the 1990s.16 Present-day irrigation projects of all types in Cochabamba, with the dilemmas they face, are built upon existing irrigation practices. The social and environ- mental history of irrigation in the region is extensive and influential, since mod- erate to large numbers of farmers there have relied on irrigated agriculture for at least 1200 years.17 Near Tarata, a provincial capital and the site of a major pre-European irrigation works (Figure 1 inset), the practice of irrigating field crops likely began as early as 1500 BC and thus may have been one of the earli- est places of irrigated farming in the Americas. Under the Inca and Spaniards the irrigated agriculture of Cochabamba was expanded and reorganized, solid- ifying its identity as the chief bread-basket of the south-central Andes. The materials used in my study of Cochabamba irrigation in the periods of Inca and early Spanish colonial rule consisted of published accounts and unpublished administrative and judicial documents (imperial, viceregal, and regional) that date to the 1500s. The following case study considered these primary and secondary historical sources in conjunction with environcultural analysis. The widespread use of two terms led to their adoption in this case study. Local canal-based irrigation in Cochabamba was referred to historically by the term suyu (which still today is widely used). The designation suyu was used by Quechua-speaking Inca administrators and colonists of Cochabamba and later by colonial Indians and Spaniards. Suyu applied both to an image of irrigation and to its actual area of operation. Ecologically and socially, the suyu in Cochabamba was the organization of irrigation according to the cluster of fields fed by a primary canal and managed according to this canal-based unit (Figures 2 and 3). In addition to irrigation, the term suyu also referred to the sociospa- tial division of rights and responsibilities that attached to the management of other resources, such as the co-ordinated rotation of fields and rangeland through sectoral fallow.18 'Basin' refers to the valley floor or bottom-land that was a scale commonly referred to in the images of Cochabamba irrigation. The English word 'basin' closely resembles the meanings of a variety of terms such as pampa and valle that were used in speech and writing in Quechua and Spanish during the periods of Inca and Spanish colonial rule. Pampa and valle, when the latter was applied to Cochabamba irrigation and land use, were terms that typically designated the entire floor or bottomland of the valley. The Valle Alto (High Valley) and Valle 156 Karl S. Zimmerer Ecumene 2000 7 (2) Central (Central Valley) formed the principal basins for Cochabamba irrigation (Figure 1 inset). Basin irrigation typically depended on the control of one or a few water sources. In Cochabamba, this scale of irrigation often came to consist of a sub-basin of the valley floor, even if irrigation was planned or imagined for the full basin area. Suyu irrigation and the web of Inca geography From their capital city of Cuzco, the armies of the Inca state conquered the inhabited mountains and coastal lowlands as far north as Pasto in present-day southern Colombia and to the south in central Chile. The Inca conquests of this realm were concentrated between about 1440 and 1500. Geopolitical state- craft of the Inca empire relied on the integration of scores of diverse ethnic groups and territories. Centred on Cuzco, the Inca state organized its vast territory into four spatial sub-units known as suyus (sometimes spelled suyos): (i) Collasuyu to the south and southeast, which included the Cochabamba valleys that were conquered in the late 1400s by the Inca emperor, Huayna Cápac (r. 14931527); (ii) Cuntisuyu to the southwest; (iii) Chinchaysuyu to the north Rescaling irrigation in Latin America 157 Ecumene 2000 7 (2) Approximately 5 Kilometers 5 4 3 2 1 El Paso Quillacollo Sacaba Sipesipe Ri Caine Ri Angostura NORTH Figure 2 ~ The Cochabamba valley (also known as the Central Valley or Valle Central) and suyu groups made by the Inca Huayna Capac.

In each of the four territories, or suyus, the provincial administrators of the Inca empire directed extensive irri- gation and agricultural terrace works.19 Their massive projects affirm the modern-day designation of the vast Inca empire as one of the world's pre- eminent 'prehistoric hydraulic states'.20 Inca state policy led to the transformation of the valleys of Cochabamba into the premier bread-basket of the south-central Andes. The ruler Huayna Cápac ordered the labour drafts and resettlement colonization that marshalled an esti- mated 14 000 agricultural workers for the state's production of irrigated maize.21 Irrigation was crucial for the success of the empire's maize growing in the Cochabamba valleys. Annual rainfalls that were probably similar to recent means of 450550 mm. (approximately 1822 in.) could not secure rainfed farming in the tropical, semi-arid climate of Andean valleys such as Cochabamba.22 158 Karl S.

The canal-centred area of the suyu served as the chief spatial unit of irrigated farming in the Cochabamba valleys during the Inca reign.24 In the main Central Valley of Cochabamba, the largest of the flat-floor grabens produced by fauling and uplift in the region, the suyus that took shape were long 'bands' or 'stripes' (Figure 2).25 Major canals brought irrigation to each of the suyu units. An esti- mated 77 suyus made up the irrigated farming of the Central Valley. In turn this large number of suyus was grouped into a total of five expansive growing areas (referred to in colonial documents as chacaras), shown in Figure 2. The Inca rulers alloted these Cochabamba chacaras and the suyus within them to the chief- tains, or kurakas, of diverse ethnic groups, to state-operated farmlands, and to the workers, known as mitimas, who were drafted for state agriculture. In other Andean valleys, such as Cuzco, the Inca state placed a similar emphasis on coor- dination of canal-centred irrigation clusters, which state administrators and local people referred to by such names as ceques.26 Suyus were also the primary spatial unit of Inca farming at the Calicanto irri- gated area near the village of Tarata in the western corner of the High Valley (Valle Alto) of Cochabamba, a large graben and presumably once a Pleistocene lake bed (Figure 1 inset). Canal remains and sedimentary deposits suggest that the Calicanto suyus were shaped like radial cones (Figure 3).27 Some suyus at Calicanto were probably constructed, or administered anyway, directly by the Inca rulers.28 This irrigated maize agriculture would have resembled the state- led production of the Central Valley, although on a reduced scale. In addition, the Inca rulers had granted a certain share of the Tarata suyus to the farmers of diverse ethnic groups. The ethnic groups at Calicanto were referred to as señorios or 'nations' in colonial documents of the sixteenth century. These irri- gators consisted of various peoples from Mizque in southern Cochabamba and other Inca subjects belonging to the ethnic groups of the chichas. (The primary residence of the chichas was located still further to the south.) With the grants of Calicanto suyus to these ethnic groups, the Inca state sought to ensure their self-provisioning of staple foodstuffs such as off-season potatoes (mishka papa). The importance to irrigation of the suyu image as a cultural concept was sug- gested by the notable extent and significance of the word's connotations. The primary gloss of suyu was 'sector'. The Inca applied this meaning to the chief territories of the state (e.g., Collasuyu, Cuntisuyu, Chinchasuyu, Antisuyu) as well as to irrigation units. These primary connotations were supplemented by other widespread usages. Indeed, the suyu root was contained in more than two dozen common terms recorded in the early colonial Quechua-Spanish dictio- naries, especially those of the Jesuit priests Fray Diego González de Holguín and Fray Domingo de Santo Tomas, who both lived for prolonged periods in south- central Andean cities such as Cuzco and Puno (Figure 1).29 Their dictionaries Rescaling irrigation in Latin America 159 Ecumene 2000 7 (2) attested to the cultural power and wide range of suyu as an Inca concept and cultural image. Suyu irrigation was not merely the vivid spatial realization of a powerful cul- tural image; it was also a product of the social processes that shaped human- induced environcultural changes. At the Calicanto suyus, the work of irrigators channelled irrigation water and water-borne sediments over a farming area of roughly 30 km2 . Their work with water and sediment guided the deposition of huge quantities of sand and silt that were transported via stream channels from the heavily eroding farmlands of the upper Calicanto watershed.30 (Accumulation of irrigation sediments in the Calicanto irrigated area were 0.54.5 m. deep by 1991.) Sedimentology of the irrigation-derived deposits at Calicanto especially the vertical continuity and the lateral or areal contiguity indicated that its waterworks were probably deployed during Inca rule as well as before. The colonizing Inca rulers probably devised suyu irrigation by adopt- ing and expanding the use of existing waterworks. Suyu irrigation hinged on the modification of various environcultural processes. Water and sediment flows and deposition, soil characteristics includ- ing moisture availability, and vegetative cover were common human-shaped mod- ifications of suyu irrigation.31 The task of irrigators at suyu sites such as Calicanto was to channel intermittent, high-energy, floodwater-type flows from mountain streams across low gradient slopes and alluvial fans such as the one that formed below Tarata. Biogeophysical changes were characteristic of irrigated fields, con- veyance canals, and drainage and discharge habitats. Presumably undertaken by Inca corvées and other groups of skilled farm labourers, these environcultural alterations helped to ensure the usefulness of suyu irrigation. Irrigation struc- tures associated with these environcultural alterations also provided an incen- tive for continued use of the suyu arrangements. The Andean valley basins, such as the Central Valley and the High Valley of Cochabamba, served as the immediate setting for collections of multiple irri- gated suyus cultivated with maize. This function of the basin demonstrated its crucial many sided role in Inca land use and politics. The Inca rulers and their subjects viewed the subtropical mountain basins and valley bottom-lands (well suited for maize growing) as one of a handful of similarly scaled environments (along with temperate alpine farmlands, grass-covered pasture and rangelands, coastal lowlands, and humid forested foothills). Taken collectively, these envi- ronments were part of a notable state policy and a conspicuous cultural ideal through which the state and its subjects, including the conquered ethnic groups, exercised direct access to the varied environments, including mountain basins, and the resources they contained.32 The image of the valley basin also was used to showcase Inca state power and its agro-environcultural prowess. Here too, the use of the valley basin was woven together with other similarly scaled environments into a web of Inca geography. The Inca state and its subjects, especially the region-scale ethnic groups or seno- rios, valued the mountain basins as a crucial node within the web of utilized environments. This web of Inca geography was later termed 'verticality' or 'vertical archipelago' (in the case of discontinuous territories) by modern-day 160 Karl S. Zimmerer Ecumene 2000 7 (2) ethnohistorians.33 A revealing account of the role of the Cochabamba basins in the web of Inca geography was authored by the remarkable auto-ethnohistorian known as 'The Inca', Garcilaso de la Vega (1539-1616) (born Gómez Suárez Figueroa to an Inca colonial noblewoman and a Spanish conquistador of Cuzco). His influential and popular Comentarios reales de los Incas, first published in Spain in 1609, gave the following account of valley basins under the Inca state: 'From all these cold provinces [Collao and the Altiplano] they [the Inca] removed many Indians at their own expense and settled them to the east . . . regions of grand fertile valleys . . . which had been uninhabited . . . totally abandoned, empty as a desert, because the Indians had had neither the knowledge nor the skill to build canals to irrigate the fields' (my translation and emphases).34 Garcilaso's passage on the mountain basins of Cochabamba blended the geo- graphical ideals of both the Inca state and Spanish colonial rulers.35 First, Garcilaso's empireexalting narrative, written in Seville, where he lived his adult life, credited the irrigated landscapes of the Cochabamba basins entirely to Inca power and knowledge. The civilizing Inca were said to have filled the previous emptiness of these places. To the colonial geography of Spaniards in western South America the Garcilaso-style rooting of geographical ideals and use pat- terns in 'grand fertile valleys' became a familar ideal: the resplendent qualities of the Andean valley basins beckoned colonists. Overall, Garcilaso's account of the Andean basins thus seemed to fuse a mixture of Inca and Spanish geogra- phies. This fusion of landscape images and geographies presumably reflected his own experiences and identity since other expressions of the 'hybrid' char- acter of Garcilaso distinguished one of the most distinctly creole perspectives on early colonial Latin America.36 Basin irrigation and the geography of Spanish colonialism Valley basins became a central focus of Spanish colonialism in western South America beginning with military conquest of the Iberian invaders. In the wake of the military defeat of the Cochabamba region in 1539, the valley settlement of Tarata in the High Valley was serving already by 1550 as a colonial district (corregimiento) and food supplier within the sprawling viceroyalty of Peru and its mountainous subdivision of Alto Peru (literally High Peru, whose approximate boundaries were Huancavelica and Jujuy: Figure 1). In the Central Valley not far from Tarata, the colonial Spaniards founded the Villa de Oropesa, later renamed Cochabamba.37 In the Cochabamba valleys the rights to the control and use of land and irrigation were at the core of myriad conflicts among colo- nial Spaniards and Indians. As discussed below, the local suyu irrigation persisted in the region albeit with major modifications. At the same time, the valley basins and their uses such as irrigation were imbued with an unprecedented value in the new Spanish colonial geography. Valley basins like the High Valley and the Central Valley of Cochabamba fired the geographical imaginations of the Spanish rulers of the Andean colony in a remarkably far-reaching fashion. A majority of early colonial town settle- ments in the Andes were located in valley basins (with notable exceptions such Rescaling irrigation in Latin America 161 Ecumene 2000 7 (2) as mining centres at Potosí and Oruro and Altiplano locations like La Paz). The High Valley had its principal settlements at Tarata and Cliza, while the early colonial towns of Quillacollo and Oropesa/Cochabamba were major settlements of the Central Valley (Figures 1 and 2). Other major valley towns in High Peru were founded by the colonial viceroyalty at La Plata or Chuquisaca (now Sucre) (15389) and Tarija (1550). By 1590 the new Peruvian viceroyalty had officially founded more than 100 valley towns in the Andes mountains between Antioquia in present-day Colombia and Tucuman in the Andean foothills of northwestern Argentina. In the colonial geography of the Spanish rulers, these Andean val- ley towns functioned as centres of military strength and political control. Many towns in the valley basins took shape through the nucleations of Indians forced to relocate from the remote uplands and surrounding mountain slopes. The preferred location in valley basins of these forced resettlements, known in South America as reducciones, simultaneously made and mirrored the power geog- raphy of Spanish Andean colonialism.38 . . . Reducciones were designed and enacted by Francisco de Toledo (r. 156981), who as viceroy was the head admin- istrator and chief architect of crown policy in western South America under the Spanish emperor Phillip II. For Toledo, securing the valley settlements of the mountainous Peruvian colony was a geopolitical imperative. In Cochabamba more than 100 pre-Spanish settlements were nucleated by colonial administrators into an estimated dozen reducción towns, all located in valley basins. Valley settlements of Cochabamba that were founded by colonial edict included Capinota, Tiraque, Mizque, Aiquile, Tiquipaya, El Paso, and Sipe Sipe (Figure 2).39 With these forced resettlements and the consolidation of the remaining rural population into Indian communities, Spain's colonial govern- ment destroyed the once powerful role of the region-scale ethnic groups or seño- rios. Indeed, the early colonial administrators purposefully dismantled the region-scale patterns of land use that powerful ethnic groups had co-ordinated under the Inca policy of verticality or vertical archipelago. Under the geogra- phy of early Spanish colonialism the Andean valley basins became, in a broad sense, the geographical successor to the once powerful regionscale webs of the ethnic groups. Farmlands around the new valley settlements of the Peruvian viceroyalty fed the colonial population centres. Irrigated where possible, the valley farmlands gained a multi-faceted importance. The economic and agro-ecological value of the valley farmlands was featured in the Spanish crown's imperial geographical reports, or relaciones geográficas. The regional reports commissioned by the Empire contained the responses of magistrates and other local officials to a stan- dardized imperial survey. Sanctioned by Phillip II (r. 155698), the 49-question survey had been drafted and distributed by imperial cosmographers and states- men through the Council of the Indies during the 1570s and 1580s.40 Preserved copies of relaciones geográficas were completed for Cochabamba in 1585 and 1586.41 According to these reports, the region was a pre-eminent supplier of foodstuffs to Spanish colonial settlements throughout the south-central Andes. Wheat, and wheat flour in particular, signified a special place for the valley basins of Cochabamba. Wheat itself was a dietary staple among colonial 162 Karl S. Zimmerer Ecumene 2000 7 (2) Spaniards, and wheat bread was a sine qua non of their accustomed cuisine, their staff of life.42 In short wheat fortified colonial rule. To colonial Spaniards and to crown administrators, the Cochabamba granary evoked the geographical image of irrigated valley basins.43 Widely read and influential accounts of High Peru (Alto Peru), the Peruvian viceroyalty, and Spanish colonial geography touted this image of the Cochabamba basins. In the early 1600s, for example, Reginaldo Lizárraga and Antonio Vázquez de Espinosa remarked on the fame of the irrigated 'valleys of Cochabamba' as premier wheat producers. The renown of the irrigated valley basins of Cochabamba as primary wheat producers stemmed also from the magnitude of inter-regional trade under Spanish colonialism. Hacienda estates located in the Cochabamba valleys, owned by Spaniards and located in the vicinity of town settlements, supplied wheat that was shipped via transport and trade circuits to colonial mining centres and other population nucleii in places unsuited to wheat growing. Most notable among these wheat importers was the mining metropolis of Potosí, a city of more than 100 000 inhabitants by 1600. The irrigation basins of Cochabamba also shipped much wheat to the Altiplano and especially the settlement of Ciudad Nueva, later renamed La Paz and made into the legislative capital of Bolivia. By treat- ing the irrigated basins as producing units, the rhetoric of official colonial reports tended to overlook wheat production and trading by Indians. Their over- sight belied the extensiveness of Indian production and commerce, including wheat cultivation and trade, that was an integral part of the colonial economy in High Peru and throughout much of the Peruvian viceroyalty.44 Irrigation was inevitably given mention in major colonial descriptions of the geography of the Cochabamba valley basins. Reginaldo Lizárraga, a high-rank- ing colonial official, predicted that irrigation of the Cochabamba valleys (taken to be the basin-wide scale) would fuel a severalfold expansion of wheat pro- duction.45 That amplification, Lizárraga claimed, would be sufficient to provi- sion wheat flour and unmilled wheat to both the burgeoning populations of Potosí and the densely settled Altiplano particularly its new colonial trade nexus at the city of La Paz. According to Lizárraga's account, the wheat from the Cochabamba valleys was the 'best in the world'. Similarly, the wheat of irri- gated Cochabamba valleys garnered high praise in other imperial compendiums on New World colonial geography. For example, high praise for irrigated wheat growing was featured in a well-known account of Cochabamba entitled 'The famous valley . . . and its district' written by the perspicacious Antonio Vásquez de Espinosa.46 Colonial geographical descriptions of Andean valley irrigation were also deeply cultural works. These mid-elevation tropical mountain valleys were dis- tinguished by a mild climate, a seasonality of precipitation, and growing condi- tions suited to wheat and a variety of Mediterranean food plants that were staples of Spanish colonial cuisine.47 Colonial accounts emphasized favourable com- parisons between these particular food-growing landscapes of the Peruvian viceroyalty and familiar southern European environs. The valley basin of Cajamarca, located in the northern sierra of present-day Peru, could be covered with wheat that 'grows as well as in Sicily', according to the pioneering Andean Rescaling irrigation in Latin America 163 Ecumene 2000 7 (2) chronicle of Pedro de Cieza de León, a soldierscribe and later chronicler whose 1553 book was widely read at the time in Spain, Europe, and the New World colonies.48 The image of the irrigated basins of the Andes wove together the imperative of strategically familiar landscapes and allusions to divine providence. Abundant instances of the latter, in which irrigated valley basins were seen as signs of earthly paradise, peppered both the pioneering and most scholarly treatises on Andean landscapes and geography.49 The irrigated basins were divinely favoured or beneficent, not to mention well suited and inviting to Spanish colonial use. In addition to irrigation, the soil fertility and climate were often registered as most favourable. Indeed, the leading chronicles of colonial landscape and geog- raphy gave the impression of a valley-specific concentration of marvels that invited and justified Spanish colonialism in the Andes in a way akin to the rhetor- ical support of Spanish imperialism throughout their New World colonies.50 Divine wonders of the Andean basins were also naturalized.51 For instance, early Spanish colonial geographical accounts compared the irrigation of mountain basins to the natural rainfall runoff from upland slopes, a process also referred to as regar. Suyu irrigation of Cochabamba did not disappear in the 1530s; rather the existing waterworks became reformulated with the onset of Spanish colonialism. To my knowledge, the suyu irrigation of Cochabamba was unmentioned by the high-ranking cosmographers, chroniclers, and chief colonial administrators of the region. A contrast to the conspicuous imperial codification of Cochabamba irrigation as valley- or basin-scale in scope, the suyu irrigation was reformed with- out official pronouncement. Suyu irrigation was remade in a manner that fitted within new colonial institutions in the irrigated valleys. Colonial land use and property institutions in Cochabamba such the encomienda, the lease to a land tract replete with tribute-paying Indian residents, and the hacienda, the well- known manorial estate, were faced with conditions, including ecological ones, that encouraged the adoption of the suyu. A growing number of Spaniards laid claim to hacienda estates of valley farm- land, together with the riparian rights to irrigation, in the Cochabamba valleys.52 Their claims were established through crowngrants, acquisitions, and frequently the outright theft of Indian resources.53 In some cases the colonial Spaniards and their workers destroyed the off-takes of Indian canal arrangements in order to divert irrigation into their own waterworks. In many cases, however, they pre- ferred the tactic of usurping the intact Indian waterworks. In the High Valley near Tarata, the canal-based territories of suyus outlined the new boundaries of Spanish colonial haciendas. These colonial estates included those such as Prado de San Luís and Mamanaca, formed in the Calicanto irrigated area.54 The largest hacienda estates, such as Chullpas, which was located midway between Tarata and Cliza, contained as many as ten suyus within its boundaries. Use of suyu-based irrigation by colonial haciendas in the Cochabamba valleys grew from a mix of the selective borrowing and alteration of existing practices. Colonial haciendas at Tarata and other High Valley sites, which were estimated to number 24 by 1692, presumably found it advantageous to 164 Karl S. Zimmerer Ecumene 2000 7 (2) adopt the technical infrastructure of suyu irrigation.55 Suyu off-takes and diver- sion weirs from the river channels, extensive networks of primary and secondary canals, drainage devices connecting between fields, and the ubiquitous embank- ments along field borders (known as 'bunds' in irrigation parlance) were key infrastructural elements. These technical features of irrigation, which had been created by the human shaping of biogeophysical processes via the labours of Indian farmers, could be converted to hacienda use. Rights to suyu irrigation were made to correspond to the legal customs of Spanish water law. In the Peruvian viceroyalty, that legal tradition was modified to make use of the rota- tional style of irrigation scheduling that had been a basis of the Inca-sponsored mit'a.56 The centrality of irrigation suyus and other canal-based spatial units was rein- forced by the resistance of colonial Indians to Spanish domination. Attempted protection of water rights became a main form of Indian resistance. Resistance efforts pivoted on the control of irrigation territory, and sometimes entailed legal tactics that appeared in judicial documents. Several legal cases were filed with respect to irrigation disputes in Cochabamba's valleys, especially its Central Valley. Following military conquest, the Peruvian viceroyalty had granted the lat- ter's farmlands, water resources, and Indian residents as two prize encomienda leases to high-ranking Spaniards. By 1540, one valley lease, held by the renowned viceregal lawyer Juan Polo de Ondegardo, was being hotly contested.57 (Juan Polo de Ondegardo was a leading expert of the Spanish empire on Inca history, land tenure, and land use.) In 1556 the leader of a group of colonial Indians known as the Paria filed suit in Spanish colonial court against Polo de Ondegardo and the Indians liv- ing on his Cochabamba encomienda.58 The Paria were an ethnic group, which had earlier been recognized by the Inca and whose principal territory was located near Oruro (Figure 1). Hernando Asacalla, the leader of the Paria Indians in 1556, deposed exhaustive information about his group's rights to land and water in the Central Valley. Asacalla's deposition showed in convincing detail how the Paria people, along with eight other ethnic groups, had been granted irrigation suyus by the Inca ruler Huayna Cápac. While their primary residence was located in Paria, located in the Altiplano about 100 km from Cochabamba, they reported that during the Inca reign their group regularly sent members to work the irrigated farmlands of Cochabamba on either a seasonal or a year- round basis. Legal efforts by Asacalla and the Paria people to regain their lost lands did not succeed, yet their desperate attempts illustrated how the everyday impor- tance of suyus and allied land units were reinforced by resource conflicts. Asacalla and the Paria people staked their water and land claims to suyu units even decades after conquest. These subjects of the Peruvian viceroyalty, like other colonial Indians, wished to demonstrate that their previous rights had been fully established under the Inca, and had then been removed illegally. Legal claims of encomenderos, hacendados, and other landowners (mostly Spaniards), for their part, also relied on claims to Inca territories such as the suyu. The tactics of these colonial landowners aimed to prove that their prop- Rescaling irrigation in Latin America 165 Ecumene 2000 7 (2) erties were descended directly from holdings of the vanquished Inca state rather than gained through the usurpation of other Indian holdings. Reinforcement of suyu territories by judicial disputes could thus stem from the actions begun either by colonial Indians or by Spaniards. Of course, the two parties tended to marshal the past traditions of suyu use for their own contrasting purposes. Deft manipulation of the contradiction was deployed by the well- informed Polo de Ondegardo in the dispute over his Cochabamba encomienda. Responding in 1540 to a local judge's issuance of a set of 14 questions, a so- called interagatorio, Polo de Ondegardo elabourated how his encomienda had con- sisted of lands that had belonged to certain Inca chacaras, which were large land areas each made up of groups of suyus.59 Polo de Ondegardo testified in the same legal deposition that these irrigated chacaras (and the suyus they contained) had never been possessed by the Paria Indians or others. Justifying his own land claim, the legalist swore that these irrigated valley lands had never been used by a nonlocal ethnic group. By relying on claims to Inca ownership, the practice of colonial law in west- ern South America was reinforcing the spatial domain of certain resource insti- tutions, in particular the suyu. This consequence was surely paradoxical, at least at first glance, for legal codes in the Spanish colonies were conceived of as major instruments for the integration of subject territories into the overseas empire. Spanish rulers counted on such codes in order to establish property rights and rules for the use of resources. Still, the colonial rulers of Andean South America were also compelled to incorporate references to Inca property precedents. Such considerations were both legal theoretic and sociopolitical.60 The importance of suyus and other canal-based territories continued amid the cascade of colonial conflicts over irrigation resources. It was noted even by Viceroy Francisco de Toledo, chief architect of the colonial design of valley-based geography. During his royal inspection (visita) of Cochabamba in 1574, Toledo reported how Indians and Spaniards were embroiled in local disputes over irri- gation at the scale of individual canals.61 Visiting the Mizque valley of southern Cochabamba, Toledo witnessed a heated dispute over irrigated land. Mizque Indians had lodged a complaint against a colonist named Diego de Valera. According to the account contained in Toledo's visita, the Indians complained that the colonist had stolen their water rights by diverting a main canal, and that he was trying to steal their lands by devaluing them. At each attempt of the Mizque Indians to rebuild the canal system, Diego de Valera was said to order his oxen teams be be used to destroy the connections of canals to their fields, thereby altering water flow and sediment transport that was crucial to irrigated farming. A similar struggle took place on the outskirts of El Paso (then Santiago del Paso), a reducción resettlement of Indians in the Low Valley located about 10 km from the Villa de Oropesa (later to become Cochabamba).62 Indian towns- people and their crown-appointed legal representative (known as the protector de los naturales) initiated the suit by addressing a letter of complaint directly to Phillip II, the Spanish emperor. The defendant in their complaint was Gerónimo de Ondegardo, heir of the famous legalist. The El Paso people and their 166 Karl S. Zimmerer Ecumene 2000 7 (2) representative denounced Gerónimo de Ondegardo for having stolen so much water that the Indians were left 'drinking it from puddles' (beberla de charcos). The lawyer of Gerónimo de Ondegardo, acting in his absence since the defen- dant resided in La Plata (later Buenos Aires), tried to marshal a defence on grounds that the disputed irrigation source and the watered farmland were derived from an Inca suyu rather than from Indian lands. If such legal disputes preserved the salience of suyus within the colonial sys- tem, just as important to their survival was their practical usefulness. Suyu irri- gation utilized by Gerónimo de Ondegardo, for example, was claimed by the defendant to produce an annual wheat crop of 300 fanegas on his estate (about 3000 kg.).63 His defence also claimed that the disputed water source provided turning power for three grist mills that ground wheat flour. Wheat and wheat flour, emblematic foodstuffs of the Spanish overseas empire, thus flowed from the reinvented use of local irrigation arrangements. The actual commonness of local, canal-based arrangements continued to contrast the image of basin-scale or valley-wide irrigation that had been created as a foundation of Spanish colo- nial geography in the Andes. Coda: the subsequent rescaling of irrigation to the grassroots The basin scale acquired further salience as the chief geographical image of Cochabamba irrigation under the later period of Spanish colonial rule. This geospatial vision culminated in the plans of late colonial Bourbon rulers. Basin- scale irrigation at Cochabamba was advocated in the survey of Francisco de Viedma, a high-ranking Bourbon administrator who directed reforms in the sprawling Intendencia of Santa Cruz.64 Following Bolivian independence from the Spanish empire in 1826, a variety of schemes for basin-scale irrigation were proposed and constructed, to varying degrees, in the Cochabamba valleys.65 Economic liberalism, foreign investment and an ethos of modernization moti- vated these basin-scale irrigation schemes. Influence of the national and mod- ern image of irrigation owed much to the conflictive encounters and geographies of Spanish colonialism, even though the more recent schemes were also created as postcolonial constructions. Basin-scale irrigation increasingly became a reality in the mid-twentieth cen- tury. Typically the modern schemes for basin-scale irrigation, which became common in Cochabamba after the populist 1952 National Revolution, sought to centralize water authority and enforce a fee agreement. Ideally, the development of modern irrigation in the region would have occurred in conjunction with populist agrarian reform. Basin-scale irrigation and allied modern institutions were exemplified by the National Irrigation System Project No. 1, otherwise known as La Angostura. Inaugurated in 1950, the La Angostura project created a large reservoir in the High Valley (known as Laguna de Angostura; Figure 1 inset) in order to irrigate a large part of Cochabamba's Central Valley. The La Angostura project was the largest irrigation scheme in Bolivia until the mid- 1990s.66 It epitomized the centralization of basin-scale irrigation projects and institutions in the prized valley bottoms. Rescaling irrigation in Latin America 167 Ecumene 2000 7 (2) Most recently, a number of development agencies, including many NGOs, are offering support to local canal-based suyu irrigation in Cochabamba.67 The region's largest example of local canal-based suyu irrigation is the Multiple-Use Laka Laka Project (Proyecto Multiple de Laka Laka). Led by a 'grassroots' NGO and funded by international aid agencies in support of 'sustainable develop- ment', the claim of the Laka Laka project is that its incorporation of suyus is ensuring the preservation of tradition. The project also believes that the local scale of its suyu irrigation traditions will ensure the socioeconomic advantage of even distribution of benefits among water users and the environcultural bene- fit of sound resource management. To date, both their claims and their promises have been hotly contested. The claim to preserve tradition is challenged espe- cially by a group of former occasional irrigators, known as tail-end users, whose fields are located at the outer ends of the earlier suyu canals. These tail-end users were excluded by the spatial planning and boundary fixing of the Laka Laka Project. Indeed, the struggles for water rights by tail-end irrigators illus- trates the blatant reinvention, based upon spatial fixing of the local scale, that is a cornerstone of the local development being undertaken at the Laka Laka Project. Similarly, local struggles have arisen over the extra-local distribution of the benefits and costs of the Laka Laka Project. These social struggles revolve around both socioeconomic and environcultural features of the project. One conspicu- ous struggle is being waged by the inhabitants of the neighbouring Calicanto uplands in the hill country west of Tarata. These upland land users are being pressed to undertake soil conservation works, perhaps even drastic measures, in response to the severe erosion that is resulting in sedimentation that threatens the irrigation works.68 The people whose principal lands are located in the upland watershed, who already were much poorer than the irrigators, are angered over the local scaling of the benefits and costs of the Laka Laka Project. The upland land users are embittered that they were excluded as participants or beneficiaries of the project and are, at the same time, being asked or even required to make sacrifices and concessions in order to implement the conser- vation measures. Conclusion: images of scale and scales of irrigation Rulers of the Inca state and the Spanish colonial empire conceived of canal- based suyus and Andean valley basins, respectively, as chief scalar images of irrigated farming. The rulers utilized these scales of irrigated farming to situate the choice irrigated landscapes of such sites as Cochabamba within their own distinct geographical orders. Irrigation of suyus and valley basins highlighted the political power of the Inca and Spanish rulers, added to their economic domination, and made more governable the nonInca ethnic groups and later colonial Indians. To empire-building Spaniards in the 1500s and 1600s, the Andean basins served to anchor a new colonial geography of the Andes. Irrigated agriculture, like forced resettlement, was emblematic of the new empire's conspicuous control of the Andean valley basins that were geopolitical 168 Karl S. Zimmerer Ecumene 2000 7 (2) strongholds in High Peru and other subdivisions of the sprawling Peruvian viceroyalty. Notwithstanding the dichotomous images of the local canal-based suyu and the larger basin unit, the scaling of irrigation took place in processes that were interlinked. Social co-ordination, conflict, and human environcultural changes conditioned a more complex and multiple-level scaling of irrigation than could be seen in the dual pair of images. Inca suyu irrigation was tied to the larger 'vertical' web of state geography that featured valley basins as a principal node. That Inca geography sought to consolidate rule over diverse ethnic groups and to co-ordinate their local land use. Intermediate-scale co-ordination of irrigation and other local resource management was central to the Inca state. Colonial Spanish administrators dismantled those scales of land use that were co-ordi- nated over region-size areas larger than strictly local communities. As part of that dismantling of existing social and environcultural processes, the new European rulers reinvented suyu irrigation as a key feature of local water man- agement that fitted into their basin-centred domination of the Andean peoples. Related rescaling and reinvention of local resource use under Spanish colo- nialism featured mit'a riparian water rights, ayllu rural communities, and manay sectoral fallow. Current development efforts in the Andean countries and throughout Latin America are heavily influenced by the contrasting images of local canal-based irrigation and basin-wide schemes. The influence of this present-day perception is deeply rooted in the irrigation geographies of the pre-European and early colonial periods, although this influence has been overlooked. Rapidly growing interests in 'local', 'grassroots', and 'sustainable development' can benefit by paying close attention to the reinvention and occasional rescaling of irrigated landscapes. Recent and ongoing changes in the use of these water resources need to be compared to former irrigation practices. Indeed, the increasing role of 'tradition' in a variety of present-day development approaches urges a criti- cal and reflexive familiarity with the existing and past geographies of irrigation. Contemporary local-scale irrigation projects, such as the suyu arrangements of the Laka Laka Project must be seen as having their own roots in colonial and modern historical geographies.69 Of special importance is how these connec- tions to the past, as well as the associated historical discontinuities, are shaping the present-day practices of irrigation. Irrigation planning would do well to abandon the preconceived dichotomy of scale between local irrigation and basin irrigation schemes. The idea of a sin- gle all-defining scale, most recently seen in local irrigation initiatives, is in need of substantial rethinking. Local irrigation must be recognized as taking shape in relation to key processes that operate at other scales such as the basin. This geographical awareness can be readily applied to the monumental contrast between local suyu irrigation under the Inca state and such recent attempts at 'grassroots' suyu irrigation as the Laka Laka Project. The former was integrated with region-scale political and economic organization and resource manage- ment. Those articulations stand in sharp contrast to most current projects of canal-based irrigation that lack scaled-up linkages. In order to move beyond a Rescaling irrigation in Latin America 169 Ecumene 2000 7 (2) priori notions of scales, the current interest in local irrigation must be sensitive to scale linkages, rescaling at multiple levels, and the joint socio-environcultural construction of scale changes. Such awareness will improve the assessment of small-scale irrigation and should improve its future viability.

Social and political economic aspects but not cultural ecological ones are dis- cussed in the existing evaluations of this minifundia formation. See Larson, Colonialism; R. H.

Murphy, Irrigation in the Bajío region of colonial Mexico (Boulder, Westview Press, 1986). 3 Within the broad scope of geographical cultural ecology I refer especially to a critical political ecology ‘which works from an ecocentric view of the biophysical environment but stresses social forces as the major causal factors’. See Buttel and Sunderlin, cited in J. Friedmann and H. Rangan, eds, In defense of livelihood (West Hartford, Kumarian Press, 1993), p. 3. This sort of political ecology is elabourated on in other descriptions. See K. S. Zimmerer, ‘Ecology as cornerstone and chimera in human geography’, in C. Earle, K. Mathewson, and M. S. Kenzer, eds, Concepts in human geography (London, Rowman & Littlefield, 1996), pp. 161-88, and R. Peet and M. Watts, eds, Liberation ecology: environment, development, social movements (London, Routledge, 1996). It also resembles the idea of a political ecology ‘that is rooted in productions of nature that hold environcultural concerns in tension with social, cultural, and political economic considerations’. See C. Katz, ‘Whose nature, whose culture? private productions of space and the ‘preservation’ of nature’, in B. Braun and N. Castree, eds, Remaking reality: nature at the millennium (London, Routledge, 1998), pp. 46-63. 4 The powerful critique and criticisms of modern Western development schemes centred on irrigated agriculture have been a major impetus for the ‘grassroots,’ ‘local,’ and ‘sustainable development’ approaches. This study’s perspective on these approaches is informed by such works as Peet and Watts, Liberation ecology ; J. Crush, ed, Power of development (London, Routledge, 1995); S. Corbridge, ‘Third World development’, Progress in Human Geography 15 (1991), pp. 311-21; A. Escobar, Encountering development: the making and unmaking of the Third World (Princeton, Princeton University Press, 1995). My study is engaged with specific aspects of these critques in the next section. 5 See, for example, E. Goldsmith, ‘Learning to live with nature: the lessons of traditional irrigation’, Ecologist 28 (1998), pp. 162-70. 6 Examples of this perspective include the following: E.

Tuan, the hydrologic cycle and the wisdom of God: a theme in geoteleology (Unversity of Toronto, Dept of Geography, 1980). 52 The early colonial records of Cochabamba irrigation give the impression that water rights were commonly regarded as appurtenant to land, although in other colonial regions of Latin America the rights to water were transferred separately.

Social and political economic aspects - but not cultural ecological ones - are discussed in the existing evaluations of this minifundia formation. See Larson, Colonialism ; R. H.

N2 - A pair of scales - local canal-based (or village-based) and basin-scale (or valley-wide) - is featured in the irrigation of the mountain landscapes of Latin America. These scales arose historically through the interplay of cultural images with the political ecologies of agrarian transformation. In the Cochabamba region of Bolivia, long the irrigated breadbasket of the south-central Andes, the Inca state (c. 1495-1539) imposed canal-based irrigation using a powerful concept of rotational sharing (suyu). Valley basins containing local irrigation were a part of the territorial web of Inca state geography known later as verticality. The Spanish empire in Andean South America (1539-1825) was predicated upon a valley-centric colonial geography. Colonial rescaling involved despoliation and usurpation of waterworks, legal actions, and struggles over environmental change. Influence of the two irrigation scales has persisted. Today canal-based irrigation is not a timeless relict of indigenous customs, pace many postcolonial projects. Rather its usefulness, and its remarkable reinvention as a cultural concept and environmental creation, are the products of major modifications. Dismantling of multi-scale linkages in irrigation has reduced indigenous or peasant cross-scale co-ordination. Local containment poses threats to the environmental and socio-economic sustainability of canal-based irrigation.
