    Wastewater: From Waste to Resource - The Case of Santa Cruz de la Sierra, Bolivia
    (World Bank, Washington, DC, 2018-03) World Bank
    A set of case studies was prepared as part of the World Bank’s Water Global Practice initiative 'Wastewater. Shifting paradigms: from waste to resource' to document existing experiences in the water sector on the topic. The case studies highlight innovative financing and contractual arrangements, innovative regulations and legislation and innovative project designs that promote integrated planning, resource recovery and that enhance the financial and environmental sustainability of wastewater treatment plants. This case study documents Santa Cruz de la Sierra, Bolivia.

    Greenhouse Gases from Reservoirs Caused by Biogeochemical Processes
    (World Bank, Washington, DC, 2017-12) World Bank
    Reduction of greenhouse gas (GHG) emissions is fundamental to the mitigation of climate change. It has become increasingly important to estimate and report on GHG emissions to enable the implementation of mitigation measures to limit or reduce total emissions. In most cases, such estimation is fairly simple, using known emission factors per surface area or per produced energy unit. However, GHG emissions from reservoirs created for the purpose of electricity generation, water security, or flood protection are very difficult to estimate, and no single emission factor or formula can be applied. The purpose of this note is therefore to provide guidance to World Bank Group (WBG) staff on how to assess GHGs from reservoirs in preparation of dam infrastructure projects. The note discusses: (i) the major biogeochemical processes causing GHG emissions from reservoirs; (ii) the state of current knowledge, and (iii) recommendations for assessing GHG emissions caused by biogeochemical processes for planned reservoirs.

    Climate Variability and Change : A Basin Scale Indicator Approach to Understanding the Risk to Water Resources Development and Management
    (World Bank, Washington, DC, 2011-09) Strzepek, Kenneth; McCluskey, Alyssa; Boehlert, Brent; Jacobsen, Michael; Fant IV, Charles
    The impact of climate change is likely to have considerable implications for water resource planning, as well as adding to the risks to water infrastructure systems and effecting return on investments. Attention is increasingly being paid to adaptation strategies at the regional and basin level; however, the current paucity of information regarding the potential risk to hydrological systems at this scale presents a substantial challenge for effective water resources planning and investment. This study is intended to help bridge the gap between high-level climate change predictions and the needs of decision-makers, including World Bank Task Team Leaders, government agencies, investors, and national economic development planners, whose programs and investments will be affected by basin- and regional-level impacts of climate change on water resources and related infrastructures. This study evaluates the effects of climate change on six hydrological indicators across 8,413 basins in World Bank client countries. These indicators, mean annual runoff (MAR), basin yield, annual high flow, annual low flow, groundwater (base-flow), and reference crop water deficit, were chosen based on their relevance to the wide range of water resource development projects planned for the future. To generate a robust, high-resolution understanding of possible risk, this analysis examines relative changes in all variables from the historical baseline (1961 to 1999) to the 2030s and 2050s for the full range of 56 General Circulation Model (GCM) Special Report on Emissions Scenario (SRES) combinations evaluated in the Intergovernmental Panel on Climate Change (IPCC) Fourth Assessment Report (AR4).
