This book is the result of a joint research effort led by the U.S. National Academy of Sciences and involving the Royal Scientific Society of Jordan, the Israel Academy of Sciences and Humanities, and the Palestine Health Council. It discusses opportunities for enhancement of water supplies and avoidance of overexploitation of water resources in the Middle East. Based on the concept that ecosystem goods and services are essential to maintaining water quality and quantity, the book emphasizes conservation, improved use of current technologies, and water management approaches that are compatible with environmental quality.
This is the eleventh report in the annual series assessing major development issues. Part I reviews recent trends in the world economy and their implications for the future prospects of developing countries. Part II examines the role of public finance in development. This report includes the World Development Indicators, which provide selected social and economic indicators for more than 100 countries. Despite continued economic growth through 1987 and into 1988, two problems have characterized recent trends: unsustainable economic imbalances within and among industrial countries, and highly uneven economic growth among developing countries. Part I of the report concludes that three interdependent policy challenges need to be addressed. First, industrial countries need to reduce their external payments imbalances. Second, developing countries need to continue restructuring their domestic economic policies in order to gain creditworthiness and growth. Third, net resource transfers, external debt, from the developing countries must be trimmed so that investment and growth can resume. Part II of the report explores how public finance policies are best designed and implemented. How deficits are reduced is crucial: controlling costs in mobilizing revenues and setting careful priorities in public spending are equally important. Efficiency in providing public services and expanding the scope for raising revenue can be achieved through decentralizing decisionmaking and reforming state-owned enterprises with the latter permitting greater private participation.
This report summarizes the findings of a collaborative effort to map and assess irrigated areas in the Limpopo Province, South Africa. The study was conducted by the International Water Management Institute (IWMI) in collaboration with the Department of Agriculture, Forestry and Fisheries (DAFF) and the Limpopo Department of Agriculture and Rural Development (LDARD), as part of the DAFF-supported ‘Revitalization of irrigation in South Africa’ project. Based on a combination of Landsat and Moderate Resolution Imaging Spectroradiometer (MODIS) satellite data, previous irrigated area mapping exercises carried out by DAFF and three-field ground truthing (GT) surveys, a total of 1.6 million hectares (Mha) of cropland were identified, with 262,000 ha actually irrigated in the 2015 winter season. The study also found that only 29% of all land equipped with center pivots was actually irrigated.
