Globally, most food is produced using soil moisture that comes from precipitation (i.e., “green” water). Moreover, most of the water that reaches plants in irrigated systems also stems from precipitation. Despite this, irrigation (or “blue”) water has typically been the focus for policy analysis, largely because it is possible for humans to manipulate blue water. This paper analyzes alternative water futures using a combined green and blue water accounting framework embedded within the water simulation components of IFPRI’s International Model for Policy Analysis of Agricultural Commodities and Trade (IMPACT). Future scenarios recently developed for the International Assessment of Agricultural Knowledge, Science and Technology for Development (IAASTD) and other studies are assessed with respect to this adjusted green/blue water accounting framework. The results reveal that accounting explicitly for green water resources broadens the scope of options for decision-makers who are seeking to improve agricultural production in the face of rising food and energy prices, a degrading water and land resource base, and increasing demands. This analysis highlight the importance of green/blue water accounting and presents a wider range of agricultural science and technology policy options for increasing global crop productivity across a span of potential futures.

Farmers in mixed crop-livestock systems produce about half of the world’s food. In small holdings around the world, livestock are reared mostly on grass, browse, and nonfood biomass from maize, millet, rice, and sorghum crops and in their turn supply manure and traction for future crops. Animals act as insurance against hard times, and supply farmers with a source of regular income from sales of milk, eggs, and other products. Thus, faced with population growth and climate change, small-holder farmers should be the first target for policies to intensify production by carefully managed inputs of fertilizer, water, and feed to minimize waste and environmental impact, supported by improved access to markets, new varieties, and technologies.

The paper develops indicators to look at the performance of the irrigation sector in Sub-Saharan Africa, where demand for food is high and irrigation has a proven potential to boost levels of agricultural productivity. By looking at six indicator categories—institutional framework, water resource use, irrigation area, irrigation technology, agricultural productivity, and poverty and food security—we assess the potential for improving performance in the agricultural food security sector through increasing irrigation sector investments. The indicators on water resource use indicate ample room for further development of the resource. The share of cultivated area equipped for irrigation in Africa is about a third of the world average and just one-sixth of the value for Asia. The low coverage of irrigation technology and the slow rate of growth in coverage clearly represent a lost opportunity for Africa and a tremendous potential for future investment and policy effort. Finally, African countries produce 38 percent of their crops (by value) from approximately 7 percent of their cultivated land on which water is managed, which again suggests that additional investment in irrigation would pay large benefits. The disproportionate contribution to agricultural production of Africa’s small irrigated area suggests that returns on additional investment in irrigation would be high, both in terms of greater food security for the continent and greater production of export-quality agricultural goods.

The increasing importance of sustainability in natural resource management is drawing increasing attention, worldwide, to the role that policiescan play in enhancing the management and allocative efficiency of water. Looking at various examples from the literature, we discuss some best-practices that have been applied in a variety of empirical settings, while highlighting some of the pit falls to avoid. We discuss the role that assigning water rights can play in creating the necessary incentives for market-based mechanisms of re-allocation to work for water management. We also emphasize the role that remains for centralized regulatory authority, and the need for collective action to ensure that essential echo-system requirements are met. Among the variety of examples cited are those of inter-sectoral transfers,conjunctive use of surface and groundwater and tradable permit mechanisms–for which we also highlight the enabling institutional requirements.

Biomass energy still dominates the energy sector in Sub-Saharan Africa, in particular as the main cooking energy source in rural and urban areas. The strong linkages to food security and the environment place biomass energy at the heart of sustainable development, a fact that is largely ignored by policy makers in favor of modern energy. At the same time, population and GDP growth are exacerbating already existing supply–demand imbalances in highly populated countries such as Malawi. These trends make it imperative to identify policy interventions that promote sustainable biomass energy while simultaneously considering linkages with other sectors. We use new data on demand and supply for biomass energy in Malawi and develop a model that estimates fuelwood demand based on actual diets and project demand in future years. We simulate how demand side interventions in the form of improved cookstoves affect biomass demand and built a behavioral model to analyze the potential of agroforestry for promoting a sustainable biomass energy sector in Malawi. Our findings show that policy measures aimed at increasing cooking efficiency are not enough to decrease demand for cooking energy due to high population growth. Supply side interventions like agroforestry on the other hand will not only increase sustainable supply, but can also enhance food security and protect the environment. We find that biomass energy can be inherently sustainable and should be an integral part of every energy sector strategy in developing countries as well as of the Sustainable Development Goals.
