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.","PeriodicalId":185153,"journal":{"name":"Research Report.

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.","PeriodicalId":185153,"journal":{"name":"Research Report.

Some research reports are narrowly focused, analytical and detailed empirical studies; others are wide-ranging and synthetic overviews of generic problems. Although most of the reports are published by IWMI staff and their collaborators, we welcome contributions from others. Each report is reviewed internally by IWMI staff, and by external reviewers. The reports are published and distributed both in hard copy and electronically (www.iwmi.org) and where possible all data and analyses will be available as separate downloadable files. Reports may be copied freely and cited with due acknowledgment. About IWMI IWMI's mission is to provide evidence-based solutions to sustainably manage water and land resources for food security, people's livelihoods and the environment. IWMI works in partnership with governments, civil society and the private sector to develop scalable agricultural water management solutions that have a tangible impact on poverty reduction, food security and ecosystem health. IWMI encourages the use of its material provided that the organization is acknowledged and kept informed in all such instances.

Uneven distribution of rainfall, droughts and high rainfall intensities contribute to low agricultural productivity and high levels of food insecurity. High population growth, the cultivation of steep and marginal lands, poor land management practices and lack of effective rainwater management (RWM) strategies aggravate the situation. Studies show that the adoption of RWM technologies is low and is influenced by several factors. This study assesses the patterns and the factors that influence farm household adoption of RWM technologies. Unlike previous studies which typically examined a single technology rather than the interdependence between technologies, the conceptual framework of this study is based on the premise that farmers are more likely to adopt a combination of promising RWM technologies. The need to consider this interdependence is one of the many recommendations made by this study to promote the adoption of RWM technologies.","PeriodicalId":185153,"journal":{"name":"Research Report.

They perceive pumps as liberating them from the ‘social’ limitations of traditional communal irrigation. However, the rapid expansion of pump irrigation is leading to increasing competition and conflict over limited water resources. We analyze the wider implications for Africa of this lack of visibility of the social dimension of pump irrigation, and offer suggestions for future policy and applied research to address the problem before it becomes a widespread crisis.","PeriodicalId":185153,"journal":{"name":"Research Report.
