    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.

    The Water-Energy-Food Nexus in the Middle East and North Africa: Scenarios for a Sustainable Future
    (World Bank, Washington, DC, 2018-06) Borgomeo, Edoardo ; Jagerskog, Anders ; Talbi, Amal ; Wijnen, Marcus ; Hejazi, Mohamad ; Miralles-Wilhelm, Fernando
    Water, energy, and agriculture have been conventionally dealt with separately in investment planning. For each of these sectors, regulatory frameworks, organizations, and infrastructures have been put in place to address sector-specific challenges and demands. As the Middle East and North Africa works towards building a more sustainable future, a nexus approach that considers the risks and synergies among these sectors is needed. To demonstrate the added value of a nexus approach, this report applies scenario analysis and integrated assessment modelling of the water-energy-food nexus to the Middle East and North Africa. The analysis finds that water scarcity increases in all countries in the region over the coming decades, mostly due to growing demands. More importantly, the analysis finds that many countries in the region could run out of fossil groundwater by 2050 unless measures to curb unsustainable abstraction are implemented. The impacts of growing scarcity on agriculture are significant, with production projected to drop by 60 by 2050 in some countries. On the upside, reducing the dependence of the agricultural and energy sectors on water and transitioning to renewable energies can reduce water scarcity, at the same time reducing greenhouse gas emissions. This report is targeted to policy makers, the academic community, and a wider global audience interested in exploring the interactions between water, agriculture, and energy.

    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.
