Morocco is expected to be faced with a major water shortfall prompted by either expansion in demand for water or reduction in precipitation induced by climate change. This paper examines the economywide impacts of these factors for Morocco. It uses a computable general equilibrium model augmented with submodules that trace consumption of water by uses and land allocation across sectors including crops, livestock, and forestry. Results show that water scarcity and changes in crop yields induced by climate change could reduce the GDP of Morocco up to 6.7 billion US dollars per year at 2016 constant prices and eliminate many job opportunities, in particular in the rural areas of this country. Only a portion of these negative impacts can be removed with improvements in water use efficiency. The factors mentioned above will reduce productivity of Morocco’s cropland and have the potential to reduce irrigated areas. Due to these changes, production of crops and food products are expected to fall, with increases in crop prices by up to 14.3 percent, assuming other factors being equal. Investment in water use efficiency practices that save water, in particular in agricultural activities, and shifting toward more valuable and less water intensive crops can help to partially mitigate these adverse impacts.

Prudent economic policies, combined with the enabling conditions created by a high endowment of water, have transformed Vietnam from a low income to a middle-income country within two decades. Though growth has produced vast benefits, it has also placed unrelenting pressures on water resources, which in turn lead to economic stresses. This report assesses how secure Vietnam’s water resources are and its economic implications and focuses on reducing the threats of “too little, too much, and too dirty.” Specifically, the report focuses on increasing water productivity in irrigated agriculture, water security and services for settlements, and on how Vietnam manages water quality and pollution issues, as well as climate change adaptation, disaster risks, and risks from infrastructure gaps and vulnerabilities. Recognizing that water governance is fundamental in addressing Vietnam’s water challenges, this report analyzes the current governance of the water sector to inform the development of strategies, provide an integrated view of challenges, and identify the most fundamental shifts needed to achieve national water security. Going forward, greater emphasis will have to be given to policy enforcement and to the incentives needed to assure greater compliance. The solutions suggested by this analysis are clustered around seven recommendations. This report was developed in close cooperation with the Government of Vietnam.

Rural regions are often seen as key sources of urban water supply, creating pressure for reallocation and potential hotspots of competition for water between cities and agriculture. How effective and equitable is reallocation from rural to urban regions, and what have we learned from the global experience? This synthesis report examines the drivers, processes, politics, and outcomes of reallocation based on a review of the literature and insights from four in-depth case studies where governments have reallocated relatively large volumes of water from rural to urban regions: Melbourne, Australia; Mokopane, South Africa; Monterrey, Mexico; and São Paulo, Brazil. The findings suggest that water reallocation can play an important role in regional development. However, reallocation projects have also been controversial because of distributional conflicts regarding who wins and loses. The concept of benefit sharing, long applied to transboundary river basin management, offers a framework for designing effective and equitable reallocation processes, shifting the focus from dividing the water to sharing the benefits among rural and urban regions. The report identifies seven key lessons for realizing the potential of reallocation and limiting the risks.

This edition, based on the original Art of Knowledge of Knowledge Exchange: A Results-Focused Planning Guide for Development Practitioners, is customized for practitioners in the water sector to facilitate designing, implementing, and measuring results from their knowledge exchange initiatives. This guide includes and refers to case studies and other examples of successful knowledge exchange initiatives in the water sector and also the lessons learned from implementing these initiatives for high development impact. It also reflects the experience of dozens of World Bank Group staff, knowledge and learning professionals, government officials, and other international and development practitioners who have successfully integrated knowledge exchange as a part of a larger change process.

Lake Toba is a unique natural asset of global significance with a rich cultural heritage located in the North Sumatra Province of Indonesia. Located 904 meters above sea level and with a maximum depth of more than 500 meters, this 87-kilometer-long lake provides a wide range of economic and environmental goods and services for more than half a million people and 400 villages in the seven districts covered by the lake's 3,658 square kilometer catchment. However, sustaining the long-term economic and environmental value of Lake Toba depends on addressing the deterioration of water quality. This technical guidance note reports on the potential benefits of using remote sensing as part of an integrated strategy to improve the monitoring and management of water quality in Lake Toba.
