    Batoka Gorge Hydroelectric Scheme: A Macroeconomic Assessment of Public Investment Options
    (World Bank, Washington, DC, 2019-01) World Bank
    Maximizing the benefits from public sector investments requires a clear, predictable, and transparent process informed by robust analyses that can facilitate multicriteria considerations of different options and alternatives. However, the tools available to governments to assess the costs and benefits of different investment strategies are often too general or specific to determine the optimal investment strategy. This paper aims to improve the tools available to facilitate the assessment of the macroeconomic implications of large infrastructure projects and enhance the capacity for management of public investment decisions. The macroeconomic assessment of public investment options (MAPIO) model was applied to the Batoka Gorge hydroelectric scheme to provide an analysis of impacts on key macroeconomic variables. The MAPIO model shows the project provides a robust financial and economic investment option with a net positive impact on the national economies in both Zambia and Zimbabwe. The estimates are considered conservative and the returns remain robust when subjecting the model to extreme assumptions to test the sensitivity of the results. However, it is important to acknowledge the model limitations, which does not include noneconomic benefits, costs, or impacts on other sectors. Any investment decision should involve a multicriteria assessment that considers the full range of options and alternatives that may be available to achieving the development objectives.

    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.
