This study attempts to re-frame the current thinking on groundwater development and the implications for food security. Groundwater is important in agriculture as it provides a reliable fallback when rainfeeding fails. It is therefore instrumental in managing risk and optimizing food production. However accessing groundwater has become habit and turned to dependency. Resources limits on many key aquifers have been exceeded and competition for groundwater has become intense. This study highlights the role of adaptive strategies in dealing with aquifer management and indicates directions of research and management.

This book provides an overview, by leading world experts, on key issues in global water and food security. The book is divided in a series of over-arching themes and sections. The first part of the book provides an overview of water and food security. The second and third sections look at global trade and virtual water trade, and provide some

Economic development, population growth and poor resource management have combined to alter the planet’s natural environment in dramatic and alarming ways. For over twenty years, considerable research and debate have focused on clarifying or disputing linkages between various forms of environmental change and various understandings of security. At one extreme lie sceptics who contend that the linkages are weak or even non-existent; they are simply attempts to harness the resources of the security arena to an environmental agenda. At the other extreme lie those who believe that these linkages may be the most important drivers of security in the 21st century; indeed, the very future of humankind may be at stake. This book brings together contributions from a range of disciplines to present a critical and comprehensive overview of the research and debate linking environmental factors to security. It provides a framework for representing and understanding key areas of intellectual convergence and disagreement, clarifying achievements of the research as well as identifying its weaknesses and gaps. Part I explores the various ways environmental change and security have been linked, and provides principal critiques of this linkage. Part II explores the linkage through analysis of key issue areas such as climate change, energy, water, food, population, and development. Finally, the book concludes with a discussion of the value of this subfield of security studies, and with some ideas about the questions it might profitably address in the future. This volume is the first to provide a comprehensive overview of the field. With contributions from around the world, it combines established and emerging scholars to offer a platform for the next wave of research and policy activity. It is invaluable for both students and practitioners interested in international relations, environment studies and human geography.

The report assesses the occurrence and impacts of drought, the current policies underlying drought management as well as the mitigation measures and responses adopted in Central Asia and Turkey, with a focus on Agriculture Sector. It is part of a series of similar studies carried out in different regions and countries of the world, with the objective of shedding light on drought effects, sensitizing policy-makers for the much needed paradigm shift to pro-active drought management planning and providing guidance for the development of such policies. The studies are carried out by FAO, in collaboration with the Water for Food Institute, University of Nebraska-Lincoln, USA, as a direct contribution to FAO's Strategic Objective "Increasing the resilience of livelihoods to threats and crises".

To feed a world population that will exceed 9 billion by 2050 requires an estimated 60% increase over current primary agricultural productivity. Closing the common and often large gap between actual and attainable crop yield is critical to achieve this goal. To close yield gaps in both small and large scale cropping systems worldwide we need (1) definitions and techniques to measure and model yield at different levels (actual, attainable, potential) and different scales in space (field, farm, region, global) and time (short and long term); (2) identification of the causes of gaps between yield levels; (3) management options to reduce the gaps where feasible and (4) policies to favour adoption of sustainable gap-closing solutions. The aim of this publication is to critically review the methods for yield gap analysis, hence addressing primarily the first of these four requirements, reporting a wide-ranging and well-referenced analysis of literature on current methods to assess productivity of crops and cropping systems.

This document presents an analysis of experience in irrigation water charging, drawn from published literature and a series of six case studies. These sources provide a broad spectrum of experience from less-developed to more-developed countries. The aim has been to make an assessment of the claims concerning irrigation water charging as a tool for cost recovery (achieving financial sustainability) and demand management (achieving resource sustainability).
