CONTEXT: Worldwide farmer managed irrigation systems have provided crops for food, feed and the market for centuries. From high mountain environments to river valleys and deltas, in all continents people have organized to construct, use, maintain, transform and sustain irrigated agro-ecosystems. In this context it is important to better understand how these systems are sustained. OBJECTIVE: The objective of this contribution is to explore and theorize through which strategies and mechanisms irrigators are able to sustain these systems in a constantly changing socio-environmental context. METHODS: The study is based on ethnographic qualitative research in four areas where farmer managed irrigation systems are sustained by irrigators (Valencia region, Spain; Ecuadorian highlands; Cambodian Mekong delta; and Tsangano district, Mozambique). Research consisted of interviews and observations in these areas and was supported by a literature review of what has been published about these systems. RESULTS AND CONCLUSIONS: Results show that farmer managed irrigation systems are dynamic systems that constantly transform but that are sustained in these changes through what we term ‘communality’. We introduce this term to point out three interrelated elements that stand at the basis of farmer managed irrigation systems sustenance, namely: commons, community and polity. Analysis of the four case studies points out that these three elements are mobilized differently by farmers depending on their socio-environmental context. We show that the mobilization of these different elements amidst internal and external challenges and conflicts, forms the basis for the longevity and sustainability of collectively managed irrigation systems. SIGNIFICANCE: In the literature on farmer managed irrigation systems collective action has been portrayed as the main pillar that sustains these systems. This contribution challenges this notion by showing that irrigation systems are sustained by a combination of individual actions, collective practices, normative frameworks and organizational forms; a sense of community; and the development of political agency (polity). Recognizing that these elements come together as site specific hybrids opens new avenues of inquiry to better understand the sustainability of farmer managed irrigation systems.

Nearly half of the world's urban population depends on aquifers for drinking water. These are increasingly vulnerable to pollution and overexploitation. Besides anthropogenic sources, pollutants such as arsenic (As) are also geogenic and their concentrations have, in some cases, been increased by groundwater pumping. Almost 40 % of Mexico's population relies on groundwater for drinking water purposes; much the aquifers in semi-arid and arid central and northern Mexico is contaminated by As. These are agricultural regions where irrigation water is primarily provided from intenstive pumping of the aquifers leading to long-standing declines in the water table. The focus of this study is the main aquifer within the Comarca Lagunera region in Northern Mexico. Although the scientific evidence demonstrates that health effects are associated with long-term exposure to elevated As concentrations, this knowledge has not yielded effective groundwater development and public health policy. A multidisciplinary approach – including the evaluation of geochemistry, human health risk and development and public health policy - was used to provide a current account of these links. The dissolved As concentrations measured exceeded the corresponding World Health Organization guideline for drinking water in 90 % of the sampled wells; for the population drinking this water, the estimated probability of presenting non-carcinogenic health effects was >90 %, and the lifetime risk of developing cancer ranged from 0.5 to 61 cases in 10,000 children and 0.2 to 33 cases in 10,000 adults. The results suggest that insufficient policy responses are due to a complex and dysfunctional groundwater governance framework that compromises the economic, social and environmental sustainability of this region. These findings may valuable to other regions with similar settings that need to design and enact better informed, science-based policies that recognize the value of a more sustainable use of groundwater resources and a healthier population.

How Ecuadorian páramos are perceived has drastically changed over the last five decades. From cold, hostile, and unproductive hinterlands, páramos have changed to become areas for biodiversity conservation and ‘water towers’ that ought to be protected to provide clean and abundant water for cities and irrigation. To understand how these changing perceptions of páramos relate to interventions and their on-the-ground negotiation by local communities, we develop the notion of imaginaries of place and explore its relations to notions of governmentality and territorialization. We show how, based on changing imaginaries of what páramos are, state and non-state interventions have tried to control the Oyacachi páramos in the Northern Ecuadorian Highlands for the specific purpose of nature and water conservation. At the same time, we show that these interventions are highly contested on-the-ground. This leads to confrontations, negotiations, and a re-definition of the imaginaries of place there exist. Our analysis expounds the relevance of understanding imaginaries of place and its close relations to interventions and their negotiation.

Adaptation to climate change has become a major policy and project focus for donors and governments globally. In this article, we provide insight into how adaptation projects mobilize distinct imaginaries and knowledge claims that create territories for intervention (the objects) as well as targeted populations (the subjects) to sustain them. Drawing on two emblematic climate change adaptation projects in Ecuador, we show how these objects and subjects are created through a knowledge production process that (a) creates a discursive climate change rationale; (b) sidesteps uncertainty related to climate change impacts; (c) fosters a circular citational practice that (self-)reinforces the project's expert knowledge; and (d) makes complex social variables commensurable based on the project's rationality, interests, and quantifiable indicators. The emerging hydrosocial territories ‘in need of intervention’ require subjects that inhabit, produce and reproduce these territories, in accordance with specific climate change discourses and practices. To manufacture and align these subjects, projects employ participatory practices that are informed by recognition politics aimed at disciplining participants toward particular identities and ways of thinking and acting. We analyze these distinct strategies as multiple governmentalities enacted through participatory adaptation projects seeking to produce specific climate change resilient hydrosocial territories and corresponding subjects.

As climate change escalates, donors, international organizations, and state actors are implementing adaptation projectsEmbedded within these adaptation projects are imaginaries of rural resilience. These imaginaries, however, are contested by individuals and collectives targeted by such initiatives. In this article, we draw on Foucault’s notion of counter conducts to understand how beneficiaries in Ecuador resist, leverage, and/or rework adaptation interventions and towards what end. We identified five counter conducts: (1) negotiating for control, (2) setting the terms for participation, (3) opting out, (4) subverting the discursive frame, and (5) leveraging longevity. We argue that these counter conducts are generative, enacting multi-scalar counter-hegemonic politics of agrarian transformation.

Mega-damming, pollution and depletion endanger rivers worldwide. Meanwhile, modernist imaginaries of ordering ‘unruly waters and humans’ have become cornerstones of hydraulic-bureaucratic and capitalist development. They separate hydro/social worlds, sideline river-commons cultures, and deepen socio-environmental injustices. But myriad new water justice movements (NWJMs) proliferate: rooted, disruptive, transdisciplinary, multi-scalar coalitions that deploy alternative river–society ontologies, bridge South–North divides, and translate river-enlivening practices from local to global and vice-versa. This paper's framework conceptualizes ‘riverhood’ to engage with NWJMs and river commoning initiatives. We suggest four interrelated ontologies, situating river socionatures as arenas of material, social and symbolic co-production: ‘river-as-ecosociety’, ‘river-as-territory’, ‘river-as-subject’, and ‘river-as-movement’.

Managers of urban water systems constantly make decisions to guarantee water services by overcoming problems related to supply-demand imbalances. A preferred strategy has been supply augmentation through hydraulic infrastructure development. However, despite considerable investments, many systems seem to be trapped in lackluster development pathways making some problems seem like an enduring, almost stubborn, characteristic of the systems: over-exploitation and pollution of water sources, distribution networks overwhelmed by leakages and non-revenue water, and unequal water insecurity. Because of these strategies and persistent problems, water conflicts have emerged, whereby social actors oppose these strategies and propose alternative technologies and strategies. This can create development pathways crossroads of the urban water system. To study this development pathway crossroads, we selected the Zapotillo conflict in Mexico where a large supply augmentation project for two cities experiencing water shortages is at stake. The paper concludes that urban water systems that are engaged in a trajectory characterized by supply-side strategies may experience a temporal relief but neglect equally pressing issues that stymie the human right to water in the medium and long run. However, there is not a straightforward, self-evident development pathway to choose from, only a range of multiple alternatives with multiple trade-offs that need to be thoroughly discussed and negotiated between the stakeholders. We argue that this development pathway crossroads can cross-fertilize technical disciplines such as socio-hydrology, and social disciplines based on hydrosocial studies, which both ambition to make their knowledge actionable and relevant.

Agricultural transformations have significantly contributed to the global market’s year-round supply of capital-intensive greenhouse-grown crops. For instance, berry production in México is increasingly relying on greenhouse systems to meet the growing demand of international markets, particularly in the USA. It is still unclear to what extent these transformations are related to land tenure, as data on greenhouse distribution often do not exist, are incomplete, or lack spatial resolution. This paper presents a support vector machine learning algorithm tool to map greenhouse expansion using satellite images. The tool is applied to the major berry-growing region of Michoacán, México. Here agricultural areas are transforming to satisfy foreign demand for berries, altering local land and water resource use patterns. We use this tool and a unique land tenure dataset to investigate (a) the spatially explicit extent to which high-input commercial agriculture (mainly the production of berries) has expanded in this region since 1989; and (b) the extent to which smallholder (ejidal) land has been incorporated into the highly capitalized agro-export sector. We combine a national dataset on ejidal land (which includes both communal and parcel land) with geospatial agricultural data to quantify the land-use changes in six municipalities in the berry-growing region of Michoacán between 1989 and 2021. We find that the development of the greenhouse berry boom can be quantified and shown with spatially-explicit detail, growing from zero to over 9,500 ha over the period, using almost one-quarter of all regional agricultural land in 2020. We further find that the capital-intensive market-oriented berry industry has been widely integrated into smallholder ejidal lands, so much so that over half of greenhouses are found there.

In the Andes, indigenous communities are being increasingly besieged because their páramos act as water providers for cities and irrigation systems downstream. This has led indigenous communities to protect their hydrosocial territories from external actors and re-create them to contest these threats. In this context, we analyse how the Kayambi community of La Chimba in the northern Sierra of Ecuador has managed to defend and secure its hydrosocial territory through the creation and re-creation of its indigenous identity and networks and related cultural politics that find expression in different forms of contractual reciprocity. As a result, the community hydrosocial territory (re)-creation itself is a weapon of resistance, a decolonising process where rural communities continuously can produce their own forms of development. This is particularly important in a context where governments in the region are relying on extractivism and in the explotation of indigenous territories.

Groundwater forms the basis for millions of rural and urban livelihoods in the Global South. Its use for irrigation has spurred widespread socio-economic development in various areas but has also led to aquifer overdraft and related socio-environmental impacts. This article presents common challenges that agricultural groundwater regulation faces in the areas of intensive use. It shows the main approaches that have been used to try to regulate and control groundwater use. These revolve mostly around direct regulation by the state; different forms of co-management between groundwater user groups and state agencies; and incentives aimed at reducing agricultural groundwater use. This review analyzes why in many contexts, these mechanisms have not led to more sustainable aquifer use. Finally, the article brings to highlight the important challenges this poses in terms of socio-environmental sustainability.

In this article we analyse how workers perceive corporate labour standards and the related work conditions in the agro-export sector of Northern Guanajuato, Central Mexico. We do so by first comparing labour standards on local farms to labour standards at an international fresh vegetable production, harvesting, processing and export company that has explicit corporate labour standards. Second, we present how workers from two rural communities of landless workers employed in the agro-export industry perceive the differences between work at local farms and work at the agro-export company. Our results show that better pay and secondary benefits resulting from corporate labour standards do not necessarily translate to perceptions of better work quality. This relates to the broader work conditions in which these labour standards are inserted. Many workers prefer work with lower labour standards but that has more convenient working hours and enables engagement in family and social activities alongside the job. Based on these results we argue that, from a sociological perspective, work quality is a situated and very context-specific notion. Therefore, higher labour standards and better pay even in contexts of cheap labour and widespread poverty are not necessarily associated by workers with higher work quality.

We are facing a global water crisis exacerbated by hydro-climatic extremes related to climate change. Water scarcity is expected to increasingly affect indigenous and marginalized populations. Supporting the sovereignty of indigenous and rural populations to create water secure futures through place-based knowledge, local management, and Community-based Adaptation (CBA) measures may help tackle this crisis. Zapotec communities in Oaxaca, Mexico have self-organized for collective action to use Managed Aquifer Recharge (MAR) to address water scarcity, resulting in a perceived increase of groundwater availability. Treating groundwater as a common-pool resource (CPR) within a sociohydrological system, the objectives of this paper are two-fold: (1) to explore how MAR may be implemented as a CBA measure, and (2) to understand what factors triggered and/or enabled the widespread implementation of MAR by Zapotec indigenous communities in the Valles Centrales of Oaxaca, Mexico. In doing so, we aim to get a better understanding of local processes while also furthering theories that relate to CBA, CPR, and sociohydrology. This paper was born from the desire of the Zapotec community members to share their experience and lessons learned so other drought-vulnerable communities might benefit.

This article explores the relations between agricultural production, international migration, wage labour and processes of differentiation among peasant households. It does so based on the analysis of the ejido Jesus Maria in the northeast of the state of Guanajuato, Central Mexico. The history of this ejido and how Mexican neoliberal policies led to increased levels of migration and proletarianization since at least the early 1990s is presented. Then, it presents how in this context the production of asparagus for agro-export developed on the irrigated lands of this ejido, showing that this process went hand in hand with social differentiation and important changes in the distribution of land and water. Then, it presents the results of a household and production survey that shows that most peasant households combine agricultural production with local urban and rural wage labour, migration, remittances and/or other economic activities. Households that can live from agriculture alone have had important capital investments in agricultural production coming from international migration and remittances. Based on these results, it argues that, as rural communities become increasingly dependent on external ‘urban/global’ capital, the rural/urban divide has become increasingly permeable with important consequences for peasant economies and related social differentiation processes.

Wastewater reuse is identified as strategic to help ameliorate scarcity in water-stressed regions around the world. However, to develop it, there is a need to better understand the social, institutional and technological contexts in which it takes place. This article develops a novel socio-technical framework to inform such an analysis and applies it to current wastewater reuse in Egypt. Our analysis highlights the different actors, management activities and practices that shape wastewater collection, transfer, treatment, discharge and/or reuse in different social, technological and environmental contexts in Egypt. It points out bottlenecks of current wastewater reuse policies and programmes.

This article explores how irrigation management transfer policies were implemented in Mali, Mozambique, Malawi and Zimbabwe. In Mali and Mozambique, where the irrigation bureaucracy controlled one large irrigation system, state agencies retained control over irrigation management despite reduced state funding. In Malawi and Zimbabwe, where the state irrigation systems and the irrigation bureaucracy were smaller, users have taken over irrigation management, but are having trouble sustaining irrigated agriculture. We show how irrigation management transfer policies were shaped by the interplay between international donors, macro-economic dynamics, national politics and the interactions with (and the nature of) irrigation infrastructure, bureaucracies and organized users.

We define and explore hydrosocial territories as spatial configurations of people, institutions, water flows, hydraulic technology and the biophysical environment that revolve around the control of water. Territorial politics finds expression in encounters of diverse actors with divergent spatial and political-geographical interests. Their territory-building projections and strategies compete, superimpose and align to strengthen specific water-control claims. Thereby, actors continuously recompose the territory’s hydraulic grid, cultural reference frames, and political-economic relationships. Using a political ecology focus, we argue that territorial struggles go beyond battles over natural resources as they involve struggles over meaning, norms, knowledge, identity, authority and discourses.

Ecuadorian state policies and institutional reforms have territorialized water since the 1960s. Peasant and indigenous communities have challenged this ordering locally since the 1990s by creating multi-scalar federations and networks. These enable marginalized water users to defend their water, autonomy and voice at broader scales. Analysis of these processes shows that water governance takes shape in contexts of territorial pluralism centred on the interplay of divergent interests in defining, constructing and representing hydrosocial territory. Here, state and nonstate hydro-social territories refer to interlinked scales that contest and recreate each other and through which actors advance their water control interests.

[EN] Groundwater flow models have been increasingly used to support policy making. A substantial amount of research has been dedicated to improving, validating and calibrating models and including stakeholders in the modelling process. However, little research has been done to analyze how the choices of model makers and steering by policy makers result in models with specific characteristics, which only allow specific modelling outcomes, and how the use of these modelling outcomes leads to specific social, economic and environmental consequences. In this study, we use the social construction of technology framework to explore the development, characteristics and uses of the groundwater model of the Mancha Oriental aquifer in Spain. The specific characteristics and functioning of this model influenced the policy implementation, implying that involving stakeholders in the development and use of models is crucial for improved democratic policy making., This work was carried out as part of the collaboration agreement between the University of Castilla–La Mancha and Wageningen University. The research is also part of Femke Rambags’ MSc Thesis. David Sanz was supported by the Grants for Stays at Other Universities and Research Centres (UCLM).

Around the world it has proven very difficult to develop policies and interventions that ensure socio-environmentally sustainable groundwater use and exploitation. In the state of Guanajuato, Central Mexico, both the national government and the decentralized state government have pursued to regulate groundwater use through direct state control, groundwater markets, energy pricing, and user self-regulation. We present and analyze these regulatory mechanisms and their outcomes in the field. We argue that the close interdependencies of these regulatory mechanisms have pre-empted the effectiveness of these policy instruments as well as that of other measures aimed at reducing groundwater use in order to advance towards sustainable exploitation levels.

Although farmers are often seen as wasting water and getting a disproportionate share of water. irrigation is losing out in the competition for water with other sectors. In cases of drought. water restrictions are overwhelmingly imposed on irrigation while other activities and domestic supply are only affected in cases of very severe shortage All over the world, farmers have been responding to the challenge posed by both short- and long-term declining water allocations in many creative ways, but these responses have often been overlooked by policy makers. This paper examines how farmers have adapted to water scarcity in six different river basins of Asia and the Middle East. It inventories the different types of adjustments observed and shows not only their effectiveness in offsetting the drop in supply but also their costs to farmers and to the environment and their contribution to basin closure. The conclusion calls for a better recognition of the efforts made by the irrigation sector to respond to water challenges and of its implications in terms of reduced scope for efficiency gains in the Irrigation sector.

Groundwater forms the basis for millions of rural and urban livelihoods around the world. Building on insights from the theory of access, in this article we present how groundwater development has brought much well-fare in many parts of the world; and how resulting intensive groundwater use is leading to ill-fare through aquifer overexploitation and processes of water accumulation and dispossession. We show the difficulty of state regulation and the modest achievements of other governance approaches that aim to solve existing groundwater problems. To study these processes we propose a framework of analysis that is based on the study of hydrosocial-networks, the political economy of groundwater and the domains and discourses that define groundwater access. Such analysis highlights the challenges of devising policies and modes of governance that contribute to social and environmental sustainability in intensively used aquifers. These we argue should build on an analysis of equity that scrutinizes the discourses, actors, powers and procedures that define groundwater access. By inciting debates on equity a first and fundamental step can be made toward advancing more inclusive groundwater governance that crucially engages the marginalized and addresses their groundwater problems, concerns and needs.

NGOs have taken up an increasing number of roles and responsibilities in Latin American societies. Based on a study of the multi-stakeholder platform, the Water Resources Forum in Ecuador, this paper shows how through the creation of a broad network of NGOs, academics, grassroots water users organizations and governmental actors; this platform has been able to contribute to the democratization of water governance. This paper analyses the international and national socio-political context in which this platform developed and traces the history and strategies that marked its development. Based on this, it argues that NGOs can play an important role in the development of more democratic and inclusive public policy making in water governance, but that the capacity of NGOs to bring about change greatly depends on the socio-political context and on the networks they are able to forge with grassroots organizations, state agencies, funders and other third sector actors.
