In the pursuit of information to support policies and actions to alleviate hunger and poverty through irrigation and drainage, this paper attempts to provide correlations between water scarcity, communities and poverty. Many reviews have found strong direct and indirect relationships between irrigation and poverty. One of the main goals of the international community is to eliminate hunger and poverty and in this perspective, through the Millennium Development Goals, much progress has been achieved and evidence obtained. Sustainable Development Goals and various other United Nations initiatives intend to move forward this agenda by making it a part of broader development frameworks. In this paper, the important elements of irrigation and drainage that affect the alleviation of hunger and poverty are discussed. These elements are grouped into governance, rights-based developments, water rights and pricing, management, efficiency improvement, and the role of technology. Both the potential and the need for innovative technology and solutions in irrigation are underlined, which can be used to cater for the challenges in different subsectors. The main focus of these solutions is on maximizing productivity and efficiency, reducing water losses, achieving sustainable intensification and managing demands on water resources and the associated trade-offs.

Historical and future projected changes in climatic patterns over the largest irrigated basin in the world, the Indus River Basin (IRB), threaten agricultural production and food security in Pakistan, in particular for vulnerable farming communities. To build a more detailed understanding of the impacts of climate change on agriculture s in the IRB, the present study analyzes (1) observed trends in average temperature, precipitation and related extreme indicators, as well as seasonal shifts over a recent historical period (1997–2016); and (2) statistically downscaled future projections (up to 2100) from a set of climate models in conjunction with crop-specific information for the four main crops of the IRB: wheat, cotton, rice and sugarcane. Key findings show an increasing trend of about over 0.1 °C/year in observed minimum temperature across the study area over the historical period, but no significant trend in maximum temperature. Historical precipitation shows a positive annual increase driven mainly by changes in August and September. Future projections highlight continued warming resulting in critical heat thresholds for the four crops analyzed being increasingly exceeded into the future, in particular in the Kharif season. Concurrently, inter-annual rainfall variability is projected to increase up to 10–20% by the end of the 21st century, augmenting uncertainty of water availability in the basin. These findings provide insight into the nature of recent climatic shifts in the IRB and emphasize the importance of using climate impact assessments to develop targeted investments and efficient adaptation measures to ensure resilience of agriculture in Pakistan into the future.

Irrigation management is facing complex challenges evolving with the transformation of agriculture, competition over resources, environmental concerns, without forgetting the critical objective of food production. Managers are ill prepared to meet these challenges and the FAO called for and initiated a massive retraining programme of engineers and managers on irrigation system modernization to address these issues, starting in Asia. Results from this first generation of interventions confirmed the lack of success of many investments and institutional reforms, gaps in capacity and training and the potential for achieving significant improvements at minimal cost by focusing on system operation. The FAO prepared new guidelines for improving system operation and management (MASSCOTE) based on service-oriented management concepts, tested them through training workshops in Nepal, India and China and is disseminating them through a second-generation training programme building on first-generation knowledge synthesis. This paper presents the FAO's strategic approach to capacity building on service-oriented management. It builds on the major lessons drawn from past programmes and is based on three interrelated thrusts: at the system, state and regional/global levels. Concepts, methodologies, lessons learned on upscaling to policy and long-term investment planning, limitations and conditions for success and future programme development are discussed. Copyright RÉ SUMÉLa gestion de l'irrigation est confrontée à des défis complexes en évolution avec la transformation de l'agriculture, la concurrence sur les ressources, les préoccupations environnementales, sans oublier l'objectif critique de la production alimentaire. Les gestionnaires sont mal préparés pour répondre à ces défis et la FAO a lancé un vaste programme de nouvelle formation des ingénieurs et cadres sur la modernisation des systèmes d'irrigation pour traiter ces questions, en commençant par l'Asie. Les résultats de cette première génération d'interventions ont confirmé le manque de succès de beaucoup d'investissements et de réformes institutionnelles, les lacunes dans les capacités et la formation et les possibilités de parvenir à des améliorations significatives à peu de frais en se concentrant sur le fonctionnement du système.

The Policy Research Working Paper Series disseminates the findings of work in progress to encourage the exchange of ideas about development issues. An objective of the series is to get the findings out quickly, even if the presentations are less than fully polished. The papers carry the names of the authors and should be cited accordingly.
