In Africa, where most agriculture is rainfed, crop growth is limited by water availability. Rainfall variability during a growing season generally translates into variability in crop production. While the seasonality of rainfall in the drier rangelands can play a significant role in productivity, rain-use efficiency (RUE)—the amount of biomass produced (in kilograms of dry matter per hectare) per millimeter of rainfall—also drives production.

The Impact of Transport Infrastructure on Agricultural Production and Poverty Reduction in the Democratic Republic of Congo
Rapports et recherchesdécembre, 2009République démocratique du CongoGiven its vast land resources and favorable water supply, the Democratic Republic of Congo’s (DRC’s) natural agricultural potential is immense. However, the economic potential of the sector is handicapped by one of the most dilapidated transport systems in the developing world (World Bank 2006). Road investments are therefore a high priority in the government’s investment plans and those of its major donors.

Although several institutional and management approaches that address the degradation of the rangelands have been tested in the dry areas of Central and West Asia and North Africa (CWANA), impact has been limited. Nonetheless, the development of National Action Plans to combat desertification highlights the interest of governments to tackle this issue. Payment for Environmental Services (PES) may be a viable policy option, though, to date, most PES programs have focused on the management of different resources (forests, watersheds).

Toward an integrated global assessment
Documents de politique et mémoiresdécembre, 2011Afrique sub-saharienne, Asie central, Asie méridionale, Amérique du Sud, Afrique, Asie, Niger, Kenya, Ouzbékistan, Inde, Cameroun, PérouAttention to land degradation and environmental pollution has increased significantly in the past 25 years, largely due to greater levels of international cooperation and recognition that local changes in land resources have global impacts. As the world’s focus on climate change increases, so, too, does the attention being paid to drought and its rise in frequency and severity.

The costs of action versus inaction
Publication évaluée par des pairsDocuments de politique et mémoiresdécembre, 2011Afrique sub-saharienne, Asie central, Asie méridionale, Amérique du Sud, Afrique, Asie, Niger, Kenya, Ouzbékistan, Inde, Cameroun, PérouIn recent years, prices of agricultural land have increased quickly, actually doubling and tripling in many parts of the world. This land value reassessment has been prompted by rising crop prices and perceived land scarcity. But even as the value of land rises, land degradation continues and investments to prevent it are lagging. Awareness of environmental risks has moved to the forefront of global consciousness during the past 25 years.

Endowed with 80 million hectares of arable land (of which only 10 percent are used), diverse climatic conditions, and abundant water resources, the Democratic Republic of Congo (DRC) has the potential to become the breadbasket of the entire African continent. Instead, the country is one of the most affected by malnutrition. The DRC has the highest number of undernourished persons in Africa and the highest prevalence of malnutrition in the world. As a result, child stunting and infant mortality rates in the DRC are also among the highest in the world.
