An in-depth assessment of the century-old Wadi Laba indigenous spate irrigation system in Eritrea. This system has relied on earthern and brushwood structures and customary water rules to support subsistence livelihoods of the Wadi Laba communities for many years. This research analyses the effectiveness of the introduction of contemporary water laws and a new headwork which endevour to increase production and standard of living. The lack of success of the new approach, compared with traditional methods of water management are discussed.

Agriculture in Sub-Saharan Africa is constrained by highly variable rainfall, frequent drought and low water productivity. There is an urgent need, heightened by climate change, for appropriate technologies to address this problem through managing and increasing the quantity of water on farmers’ fields – water harvesting. This book defines water harvesting as a set of approaches which occupy an intermediate position along the water-management spectrum extending from in situ moisture conservation to irrigated agriculture. They generally comprise small-scale systems that induce, collect, store and make use of local surface runoff for agriculture. The authors review development experience and set out the state of the art of water harvesting for crop production and other benefits in Sub-Saharan Africa. This includes an assessment of water harvesting schemes that were initiated two or three decades ago when interest was stimulated by the droughts of the 1970s and 1980s. These provide lessons to promote sustainable development of dryland agriculture in the face of changing environmental conditions. Case studies from eight countries across Sub-Saharan Africa provide the evidence base. Each follows a similar format and is based on assessments conducted in collaboration with in-country partners, with a focus on attempts to promote adoption of water harvesting, both horizontally (spread) and vertically (institutionalization). Introductory cross-cutting chapters as well as an analytical conclusion are also included.

The book provides a comprehensive overview of the hydrology of the Nile River, especially the ecohydrological degradation and challenges the basin is facing, the impact of climate change on water availability and the transboundary water management issues. The book includes analysis and approaches that will help provide different insights into the hydrology of this complex basin, which covers 11 countries and is home to over 300 million people. The need for water-sharing agreements that reflect the current situations of riparian countries and are based on equitable water- sharing principles is stressed in many chapters. This book explores water resource availability and quality and their trends in the basin, soil erosion and watershed degradation at different scales, water and health, land use and climate change impact, transboundary issues and water management, dams, reservoirs and lakes. The link between watershed and river water quantity and quality is discussed pointing out the importance of watershed protection for better water resource management, water accessibility, institutional set-up and policy, water demand and management. The book also presents the water sharing sticking points in relation to historical treaties and the emerging water demands of the upstream riparian countries. The need for collaboration and identification of common ground to resolve the transboundary water management issues and secure a win-win is also indicated.

The lack of sufficient access to clean water is a common problem faced by communities, efforts to alleviate poverty and gender inequality and improve economic growth in developing countries. While reforms have been implemented to manage water resources, these have taken little notice of how people use and manage their water and have had limited effect at the ground level. On the other hand, regulations developed within communities are livelihood-oriented and provide incentives for collective action but they can also be hierarchal, enforcing power and gender inequalities. This book shows how bringing together the strengths of community-based laws rooted in user participation and the formalized legal systems of the public sector, water management regimes will be more able to reach their goals.

"Climatic Change and Water Resources in the Middle East and North Africa" is dedicated to high-priority topics related to the impact of climate change on water resources in a water scarce region. The subject is described and discussed in three main chapters and different case studies. The three main chapters are (1) Climatic changes - sources and effects on the water cycle, (2) Impact of climate change on water resources, (3) Water resources and water management. These chapters are split up into further 26 sections. A total of 64 individuals from many countries have made contributions to this book. All topics in this book are complimentary and contribute to a comprehensive understanding of the interactions between global climate change, world water cycle and water resources. A valuable and meaningful interdisciplinary mixture of topics is combined in this book which will be of great interest to many scientists.

Water policy initiatives often run into difficulties when they encounter the realities of really existing societies. Policies may not get implemented as planned, and may not achieve their stated objectives. Many things happen when policy initiatives travel from formulation to implementation. The papers in this volume examine the travel and appropriation of water policy by looking at the contestation and the embeddedness of water policy. Organised in the sequence everyday politics of water, politics of water policy, hydropolitics, global water politics, the papers constitute a call for a policy approach that replaces a social engineering with a strategic action perspective.

This paper presents a synthesis of 15 success stories in the production, processing, and marketing of high-value food products (HVF) in developing countries in Asia, Latin America, and Africa. High-value food products, such as fresh and processed fruits and vegetables, meats, fish, dairy products, and vegetable oils, are defined as having high intrinsic value or a high rate of value added through processing. Trade in these products has expanded while trade and prices for other agricultural products, such as most staple crops, have stagnated or declined. The growing trade in HVF has prompted policymakers in developing countries to examine more closely how they can expand and diversify their exports of these products. This study explores the technical, organizational, and commercial challenges facing those in HVF export development. It identifies common market and institutional factors that have contributed to the growth and international competitiveness in HVF trade. Particular note is made of the roles of the private and public sectors and of the effect of the policy environment. It examines the effect of institutional coordination on the stages of production, processing, and trade. An annex summarizes 12 case studies of the development and performance of food commodity markets. It includes export of fresh vegetables from Kenya in the 1960s, shrimp from Thailand in the 1970s, and processed tomatoes from Chile in the 1980s.
