Effective poverty reduction programs require careful measurement of poverty status. Several studies have shown conceptually that assets reflecting productive capacity form a more robust basis for identifying the poor than do flow variables such as expenditures or income. Nonetheless, little work has empirically compared poverty measurements based on assets and expenditures. This paper uses panel data from Ethiopia to generate an asset-based poverty classification scheme. Regression results are used to estimate an asset index and classify households into categories of structural poverty.

Poverty and malnutrition are significant problems in South Africa. The vast majority of poor people in the country are black and live in rural areas (RDP 1995; SALDRU 1994). Unemployment in South Africa is extremely high, female-headed households and black children are particularly vulnerable, and basic services are inadequate.' The poorest segments of South African society are overwhelmingly dependent upon a mix of social pensions, remittances, low wages, piece jobs, and, to a small extent, agricultural production. The nutritional situation in South Africa is as alarming.

Clearly defined and legally enforceable water rights and responsibilities for water operators and users in an irrigation system are the foundation underlying the incentives for conserving water and improving irrigation efficiency.

The outbreak and spread of Asian-lineage highly pathogenic avian influenza (HPAI) from Asia to Europe and Africa in 2003-2007 challenged national disease surveillance and response programs particularly in those countries where infection occurred. Ethiopia has not had the disease, but it is considered as being vulnerable because it lies under the pathway of migratory birds and has an expansive border that makes it difficult to control cross-border trade in poultry and poultry products.

Cash transfer programs are rare in Sub-Saharan Africa. This paper describes the evolution of a cash transfer program in major urban centers of Mozambique, from its inception in 1990 through two major reorganizations until October 1998. Appropriate design, strong multisectoral political support and adequate administrative capacity are critical factors determining the success of such programs.

For thousands of years, the Yellow River Basin (YRB) has been the cultural and economic center of China. The nutrient-rich soils transported by the river from the Loess Plateau have supported an economy largely based on agriculture-and increasingly irrigated agriculture. Since the 1978 reforms, industries began to develop in the lower river reaches; since then, industries have gradually expanded westward toward relatively cheaper labor and more abundant raw materials.

Human activities such as fossil fuel burning and deforestation have significantly increased the atmospheric concentration of greenhouse gases (GHG) leading to global climate change. Global climate change and its associated weather extremes pose considerable challenges worldwide, and mitigating the adverse impacts of climate change is a high priority for the international community. To reduce global emissions and curb the threat of climate change, many countries are participating in carbon trading.

"Migration can serve as an outlet for employment, higher earnings, and reduced income risk for households in developing countries. We use the 2004–2005 Human Development Profile of India survey to examine correlations between the receipt of remittances from internal migrants and human capital investment in rural areas. We employ a propensity score–matching approach to account for the selectivity of households into receiving remittances. We interpret the results conservatively due to the cross-sectional nature of the data.

"Tomato, cabbage, and garden egg (African eggplant, or Solanum aethiopicum) are important crops for small-scale farmers and migrants in the rural and peri-urban areas of Ghana. Genetic modification has the potential to alleviate poverty through combating yield losses from pests and diseases in these crops, while reducing health risks from application of hazardous chemicals.

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.

This paper draws together findings from different elements of a research project examining critical components of pro-poor agricultural growth and of policies that can promote such growth in poor rural economies in South Asia and Sub-Saharan Africa. Agricultural growth, a critical driver in poverty reducing growth in many poor agrarian economies in the past, faces many difficulties in today's poor rural areas in South Asia and Sub-Saharan Africa. Some of these difficulties are endogenous to these areas while others result from broader processes of global change.
