Book Description
As we enter an era of increasing water scarcity, there is a growing interest to find ways to capture and put water to more productive uses. Substantial increases in the productivity of water in agriculture are needed to meet the demands for food and ensure environmental security, and to satisfy the demands for non-agricultural uses. However, increasing water productivity in rice-dominated agriculture is a function of the irrigation infrastructure, advances in rice-plant breeding, and the physical, institutional and socioeconomic environments. This paper first describes the potential ways in which increased water productivity can be achieved in the context of rice production in Asia. It then illustrates the ways in which the differences in the environmental context affect the ability to increase water productivity, the approaches used and the incentives to do so. This is explained using two ‘case studies’ reflecting the experiences of Taiwan and the Philippines over the past half-century.

Book Description
The Volta River is one of the major rivers in Africa. In this study, a dynamic regional climate model (CCLM), a hydrological model (SWAT) and a water resource model (WEAP) were used to provide an assessment of one downscaled ‘middle impact’ climate change scenario on the performance of existing and planned irrigation and hydropower schemes. The results indicate that, by the middle of the twenty-first century, altered climate is likely to undermine the technical performance of existing and planned reservoirs, which will, in turn, affect development outcomes. Future water resources development in the basin requires interventions that bolster resilience and water security. Much more systematic planning of water storage, greater cooperation between the riparian states and consideration of innovative approaches to water storage are needed.

Book Description
This book examines the role of agriculture in the economic transformation of developing low- and middle-income countries and explores means for accelerating agricultural growth and poverty reduction. In this volume, Mellor measures by household class the employment impact of alternative agricultural growth rates and land tenure systems, and impact on cereal consumption and food security. The book provides detailed analysis of each element of agricultural modernization, emphasizing the central role of government in accelerated growth in private sector dominated agriculture. The book differs from the bulk of current conventional wisdom in its placement of the non-poor small commercial farmer at the center of growth, and explains how growth translates into poverty reduction. This new book is a follow up to Mellor’s classic, prize-winning text, The Economics of Agricultural Development. Listed as a Best Books of 2017: Economics by Financial Times.

Book Description
This paper presents a comprehensive assessment of the water storage properties of glaciers and seasonal snow, carried out for the first time at a major river basin scale, for the Indus, Ganges, Brahmaputra, Amu Darya, Syr Darya and Mekong basins. It analyzes the changes of glaciers and snow under recent climate change, i.e., between the baseline (1961-1990) and current (2001-2010) periods. The paper also addresses climate change sensitivity of glacier systems and the changes that might be expected under a warming scenario for the end of the twenty-first century.

Book Description
More than 1 million hectares of urban land in India could be irrigated for crops if wastewater was made safe for use. Lack of systematic data collection by municipalities makes it difficult to accurately assess the wastewater generation or estimate the total amount of urban area under wastewater irrigation, so the potential of urban and peri-urban farming could be even greater. This study attempted to analyze the current status of wastewater generation, its uses and livelihood benefits especially in agriculture, based on national data and case studies from Ahmedabad, New Delhi, Hyderabad, Kanpur and Kolkata.

Book Description
By affecting evapotranspiration and influencing how water is routed and stored in a basin, forests, wetlands and floodplains play a crucial role in the hydrological cycle. Although they are widely attributed a major role in regulating flows (i.e., both attenuating floods and maintaining flow during dry periods), these services are rarely factored into the planning and management of water resources. One reason for the failure to include them is lack of understanding. Very often the extent to which natural regulating functions really occur is unclear. Against this background, this report describes a simple, pragmatic approach for quantifying the flow regulating functions of natural ecosystems. The method has been applied at 14 locations in the Zambezi River Basin.

Book Description
By mitigating the vagaries of climate variability, agricultural water storage is widely anticipated to make a key contribution to climate change adaptation in Africa. However, if the planning of water storage is not improved, it is likely that many investments will fail to fully deliver intended benefits. This report describes the agricultural water storage continuum and some of the possible implications of climate change. A simple diagnostic tool which can be used to provide a rapid evaluation of the need and effectiveness of different water storage options, under existing and possible future climate conditions, is presented.

Book Description
Participatory research is increasingly recognized as being useful for conducting multiple activities in research for development projects. The co-learning environment created in participatory research helps to identify existing social and technological gaps, and develop possible solutions to improve the livelihoods of rural communities. This report describes a participatory approach used in the establishment and implementation of hydrometeorological monitoring networks in the Blue Nile River Basin of Ethiopia. The networks were established with the involvement of rural communities and other stakeholders to gain insights into the hydrological processes of the watersheds, in order to improve rainwater management strategies. Local people were involved in the day-to-day management and maintenance of the networks. The participatory approach proved beneficial for several reasons, not least, because it instilled trust and goodwill amongst the communities.

Book Description
The Multi-stakeholder Policy Formulation and Action Planning approach was applied in the context of a multi-city study to influence and/or change policies that govern urban agriculture practices in three African and two Asian countries. Although the approach was successful and resulted in remarkable outcomes, it showed space for improvement to facilitate its application. The study also showed that there are significant regional differences in how best to achieve policy change, which require careful attention in order to achieve the highest returns on investment in the facilitation of impact pathways.
