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.

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.

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.

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.

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.

The irrigation sector is usually the first water user to be restricted in case of drought and agriculture is most affected. It is very important for water planners to better understand the relationship between a water deficit and agricultural performance in times of drought. This paper examines the 1999-2002 drought in the Zayandeh Rud basin, central Iran. It reviews the impact of dam management, the impact of supply reduction on water allocation and agricultural production, and examines the coping strategies used by farmers at the local level. It shows that although volumes diverted were greatly reduced (and were even zero in 2002) the impact on production was much less, due to a series of adjustment and massive substitution of groundwater for surface water.
