The impacts of climate change on agriculture and food production in Southeast Asia will be largely mediated through water, but climate is only one driver of change. Water resources in the region will be shaped by a complex mixture of social, economic and environmental factors. This report reviews the current status and trends in water management in the Greater Mekong Subregion; assesses likely impacts of climate change on water resources to 2050; examines water management strategies in the context of climate and other changes; and identifies priority actions for governments and communities to improve resilience of the water sector and safeguard food production.

There is ample evidence to suggest that Sri Lanka’s climate has already changed. However, the bigger question of national importance is what Sri Lanka’s climate will look like in 50 or 100 years and how prepared the country is to face such changes. This report reviews the status of climate change (CC) research/activities in Sri Lanka in terms of observed and projected climatic changes, their impacts on water resources and agriculture, CC mitigation and adaptation, and research needs. The study also developed a pilot level CC Vulnerability Index, which was subsequently mapped at district level. The maps indicate that typical farming districts such as Nuwara Eliya, Badulla, Moneragala, Ratnapura and Anuradhapura are the most vulnerable to CC due to their heavy reliance on primary agriculture.

Water infrastructure is an essential element in water management. Together with institutions, policies and regulation, it provides basic services to growing populations, especially in developing countries, where much of the growth is taking place. In the Asia-Pacific region, for instance, populations are growing not only in size but also in affluence, straining further the existing infrastructure and demanding urgently the development of a new one. While 79% of total water use in Asia occurs in agriculture, the fastest increases in demand are emanating from industry and from urban areas. This trend is a natural consequence of the fastest industrialization and urbanization process in history. By 2030, more than 55% of Asia’s population will live in urban areas, an increase of 1.1 billion people. Nevertheless, water infrastructure is of concern not only in the global South but also in the North, where much of the drinking-water infrastructure needs upgrading or replacement, a significant undertaking as infrastructure is more than a hundred years old in many cases. The American Water Works Association estimates that changing all of the water pipes in the United States would cost more than USD 1 trillion. In this book, in-depth case studies on water infrastructure challenges and policy solutions are presented from different parts of the world. This book was published as a special issue of the International Journal of Water Resources Development.

Revisiting Dominant Notions A Review Of Costs Performance And Institutions Of Small Reservoirs In Sub Saharan Africa

This report investigates the dynamics of one of the most common agricultural water management practices of sub-Saharan Africa, i.e., small reservoirs. Small reservoirs dam permanent or temporary river flows and support multiple livelihood activities (livestock watering, crop cultivation, fisheries, small handicrafts, etc.) while providing water-related ecosystem services (soil and water conservation, flood and drought mitigation, etc.). Gathering evidence from four sub-Saharan countries, Burkina Faso, Ghana, Ethiopia and Zambia, this report calls for revisiting our understanding and assessment of the costs, performance and institutions for the management of small reservoirs. A more holistic analytical approach is the first step towards an integrative governance framework. This, in turn, holds the promise of sustainable management of small reservoirs.

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.
