Book Description
This book describes the ecosystem of the Andean watersheds, covering the Californian valley, tropical Andes, and southern Andes. Case studies of the new methods and techniques used for hydrological research in the Andes are provided, and sustainability issues pertaining to Andean water resources are discussed in the context of climate change, social and economic issues, and public policy. Furthermore, the impact of economic development on the Andean ecosystem, specifically the effect on the water cycle and the water-energy-food nexus, are examined.

Book Description
While a large number of foreign and state initiated water management systems have failed for various reasons, locally developed water harvesting systems have proven their viability by surviving for hundreds of years. While there has to be some recognition of the geographical limits and some questions asked about the quality of these water supplies, even with these detractors accounted for, these systems often remain superior to those imposed by political and private interests, not only in terms of their reliability, but also in terms of their flexibility and more equitable control. This book offers a closer look at Andean flexible strategies for securing water resources under demanding climactic conditions and during environmental changes. The book identifies a range of initiatives that have been created by and for members of indigenous communities to address challenges, such as traditional structures for collecting run-off and rainwater. It poses the questions: How have these strategies been formed and made to operate? What positive and negative lessons can be learned from the interplay between local knowledge, subsistence strategies, and the influx of knowledge and initiatives from the outside? The book highlights the wider political and economic context of local knowledge about water harvesting and its uses, and the impact of contrasting management strategies on social development in the local communities involved. Together with the management of land, the management of water resources frequently provides the basis of social institutions and relationships to which ideas of belonging and community membership are tied. Water resources, along with other natural resources, comprise not only a vital element of subsistence, but also a vital field of social and political interaction and practice.

Book Description
This volume is an analytical summary and a critical synthesis of research at the International Water Management Institute over the past decade under its evolving research paradigm known popularly as 'more crop per drop'. The research synthesized here covers the full range of issues falling in the larger canvas of water-food-health-environment interface. Besides its immediate role in sharing knowledge with the research, donor, and policy communities, this volume also has a larger purpose of promoting a new way of looking at the water issues within the broader development context of food, livelihood, health and environmental challenges. More crop per drop: Revisiting a research paradigm contrasts the acquired wisdom and fresh thinking on some of the most challenging water issues of our times. It describes new tools, approaches, and methodologies and also illustrates them with practical application both from a global perspective and within the local and regional contexts of Asia and Africa. Since this volume brings together all major research works of IWMI, including an almost exhaustive list of citations, in one single set of pages, it is very valuable not only as a reference material for researchers and students but also as a policy tool for decision-makers and development agencies.

Book Description
First published in 1997, this volume asks whether Africa’s future is necessarily rooted in peasant agriculture. The title of this book, Farewell to Farms, is deliberately intended to challenge the widely held view that Africa is the world’s reserve for peasant farming. African rural populations are themselves moving away from a reliance on agriculture. ‘De-agrarianisation’ takes the form of urban migration as well as the expansion of non-agricultural activities in rural areas providing new income sources, occupations and social identities for rural dwellers. Using recent continent-wide case study evidence, the authors assess the impact of de-agrarianisation on household welfare, business performance and national development. Their findings, which reveal new economic trajectories and social patterns emerging from a period of accelerated change, call into question assumptions about Africa’s future place in the world division of labour.

Book Description
This book offers a broad and global level description of the current status of wastewater use in agriculture and then brings the readers to various places in the MENA Region and Europe to explain how some countries and regions have addressed the challenges during implementation. On a global scale, over 20 million hectares of agricultural land are irrigated using wastewater. This is one good, and perhaps the most prominent, example of the safe use potential of wastewater. Water scarcity and the cost of energy and fertilisers are among the main factors driving millions of farmers and other entrepreneurs to make use of wastewater. In order to address the technical, institutional, and policy challenges of safe water reuse, developing countries and countries in transition need clear institutional arrangements and more skilled human resources, with a sound understanding of the opportunities and potential risks of wastewater use. Stakeholders in wastewater irrigation who need to implement from scratch or improve current conditions, find it difficult to gather the necessary information on practical implementation aspects. The main objective of this book is to bridge that gap.
