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.

Malnutrition is widespread in Nigeria, especially in rural areas. Nigerians are vulnerable to chronic food shortages, erratic supply, poor quality food, and fluctuating food prices. The huge investment in ensuring food and nutrition security for Nigerians has had limited success, and therefore, there is a need to review and learn from past interventions. This brief provides a glimpse at rural food and nutrition security in Nigeria and highlights gaps in existing knowledge and capacity to analyze Nigeria's food and nutrition security situation.

These theories of change were developed to help the HarvestPlus program deliver on its planned outcomes and impacts. HarvestPlus expects to contribute to the reduction in micronutrient deficiency among women and children in rural areas of developing countries through the breeding and dissemination of staple crop varieties with increased levels of key micronutrients.

Evidence from Nigeria
Documents de politique et mémoiresdécembre, 2011Afrique, Afrique sub-saharienne, Afrique occidentale, NigériaThis study compares the impacts of integrated soil fertility management (ISFM) on crop production with use of either mineral fertilizer or organic manure alone. We also investigate the conditions under which .ISFM technology has greater beneficial effects on yields and the factors constraining its uptake. To answer these questions, the study uses a cross-sectional, plot-level data set collected in Nigeria by the International Food Policy Research Institute and the World Bank in 2009.

Despite the rapid pace of urbanization taking place in Nigeria, half of Nigerians (approximately 70 million individuals) still live in rural areas; most of them engaged in smallholder semi-subsistence agriculture. Agriculture remains a crucial sector in the Nigerian economy, being a major source of raw materials, food and foreign exchange; employing over 70 percent of the Nigerian labor force, and serving as a potential vehicle for diversifying the Nigerian economy.

Malnutrition rates among children 0-36 months and women of reproductive age in Nigeria are high and vary significantly across rural-urban locations, geopolitical regions, and agroecological zones, constituting a significant public health challenge. Using National Demographic Health Survey (NDHS) 2003 data, we sought to understand better what the determinants of child and maternal nutrition are and whether they differ significantly in terms of their nature, levels, and effects across these domains.

In Nigeria, conventional financial institutions serve only about 35 percent of the active population, and the poor, especially women, have limited access to financial services. Private sector-led microfinance institutions (MFIs) are increasingly playing a role to fill this need. This brief provides an overview of the institutional environment of microfinance in Nigeria, as well as insights and recommendations for better reaching this audience, based on focus group discussions and case studies of self-employed women in rural areas of Edo State, Nigeria.
