    Lesotho WEAP Manual
    (World Bank, Washington, DC, 2017-02-08) World Bank
    This analysis looks specifically at the need to ensure continued development of water resources within Lesotho and aims to empower stakeholders to act with more confidence by demonstrating that the implementation strategies can provide benefits to water resources management over a broad range of possible future scenarios. The analysis quantifies a range of possible future conditions to demonstrate the benefits that can be realized over a broad range of possible future outcomes. This quantification is based on a water resource decision support model developed specifically for Lesotho, using the Water Evaluation and Planning (WEAP) model which couples climate, hydrologic, and water management systems to facilitate an evaluation of the uncertainties and strategies of impacts on specified management metrics. The WEAP model was used to simulate the historic climate based on data from the national government archives and global datasets available in the public domain. These included 121 downscaled Global Climate Model (GCM) projections of future climate over two possible water demand future scenarios, for a total of 244 scenarios up to the year 2050. The analysis concludes the following: (a)Climate change has important determinants for the future, long-term sustainable macroeconomic development of Lesotho: (b)Domestic and industrial water security is highly vulnerable under historical and current climate conditions, as well as under the full range of climate future scenarios; (c) Agriculture production will remain vulnerable to inter-annual variability over the coming decades, particularly with continued reliance on rain fed agriculture; and (d) The Lesotho Highlands Water Project (LHWP) will continue to reliably meet transfers to South Africa over the coming decades unless climate conditions are about 5 percent drier or more than the historical record.

    Sierra Leone : Public Expenditure Review for Water and Sanitation 2002 to 2009
    (World Bank, Washington, DC, 2011-07) Bennett, Anthony ; Thompson, Darrell ; van Ginneken, Meike
    This review focuses on how public expenditure translates into the delivery of water supply and sanitation services in rural and urban areas in Sierra Leone. It describes the legal and institutional framework for the allocation of resources assesses access to Water Supply and Sanitation (WSS) services and past sector performance, and analyzes public expenditure in the sector, including the factors affecting the efficiency of use of resources, and makes recommendations. Water supply includes the supply, distribution, and usage of water for drinking, food preparation, and hygiene. Sanitation is defined as the sanitary disposal of liquid waste and the promotion of hygienic practices. The review covers the period from 2002 to 2009, a period of reconstructing after a decade of upheavals. Since 2002, democracy and a stable environment for development have been re-established in the country, especially since the 2007 presidential elections. Sierra Leone remains one of the poorest countries in the world.

    Appropriate Groundwater Management Policy for Sub-Saharan Africa: In Face of Demographic Pressure and Climatic Variability
    (World Bank, Washington, DC, 2011) Tuinhof, Albert ; Foster, Stephen ; van Steenbergen, Frank ; Talbi, Amal ; Wishart, Marcus
    This paper provides an overview of major groundwater issues for Sub-Saharan Africa, with an assessment of their policy implications in terms of potential development and appropriate management. In terms of construction time, capital outlay and drought resilience, groundwater is the preferred source to meet most water-supply demands, despite hydro geological complexity, natural constraints on water well yields and quality, and institutional weaknesses. The 'new developmental agenda' relates to improving urban water-supply security and expanding irrigated agriculture to meet these challenges many countries need to undertake strategic assessment of their groundwater and prioritize investment on institutional strengthening so as to facilitate appropriately-managed groundwater development. Without effective use of available groundwater resources, improved livelihoods and climate-change adaptation will prove much more difficult to achieve.
