| The world food and financial crises threaten to undermine the real incomes of urban consumers in eastern and southern Africa. This study investigates patterns in staple food prices, wage rates, and marketing margins for urban consumers in Kenya, Malawi, Mozambique, and Zambia between 1993 and 2009. There is high correlation among wage rate series for various government and private sector categories. We find that average formal sector wages rose at a faster rate than retail maize meal and bread prices in urban Kenya and Zambia between the mid-1990s and 2007. Although the 2007/08 food price crisis partially reversed this trend, the quantities of staple foods affordable per daily wage in urban Kenya and Zambia during the 2008/09 marketing season were still... |

| Today’s resource boom in Africa, driven by Asian economic growth, offers new opportunities for resource-rich African countries. Contrary to the experience of previous booms, however, most mining profits now accrue to foreign companies, leaving little room for governments to use revenues for pro-poor investments or to mitigate adverse distributional impacts. Taking Zambia as a case study, this paper shows that despite privatization, Dutch disease remains a valid concern and may hamper economic diversification, worsen income distribution, and undermine poverty reduction strategies. Mining royalties must, therefore, be increased and used to finance growth-inducing investments that encourage pro-poor economic diversification, else many African countries will... |

| The Insect Resistant Maize for Africa (IRMA) project is currently developing Bt maize for Kenya. So far, Bt genes with resistance to Chilo partellus, Chilo orichalcociliellus, Eldana Sacharina, and Sesamia calamistis, four of the five major stemborers were successfully incorporated into elite CIMMYT maize inbred line (CML216) and tested in insect bioassays in Kenya. Participatory Rural Appraisals showed that stem borers are indeed a major pest problems for farmers. Four seasons of on-farm crop loss assessment showed an average crop loss of 13.5%, or 0.4 million tons, valued at US$ 80 million. If the project manages to find a Bt gene that is effective to the fifth stemborer, Busseola fusca, adoption rates are likely to be high, and therefore the returns.... |

| The economic reforms in maize marketing and trade policies implemented during the 1990s have been highly controversial, and there remains a lack of solid empirical investigation on the impacts of these reforms on national food security, price stability and rural income growth. This study aims to provide a detailed evidence-based analysis of the impacts of maize marketing and trade policies on smallholder agricultural production growth, access to food by consumers, and other important national policy objectives. These insights from Zambia can hopefully move forward the continuing debate in the region on how maize marketing and trade policies should be structured in the future. |

| After reviewing trends in the production and marketing of fresh produce for the domestic market in Kenya since 1997, this paper presents detailed information on the structure of the flow of this produce from rural areas to wholesale markets in Nairobi and from those wholesale markets to assorted retail markets. Market shares are estimated by product for geographic areas supplying Nairobi, and for each important wholesale and retail market in the city. It is found that horticultural production for the domestic market is keeping up with rural population growth but not with the much faster urban population growth. The urban wholesaling and retailing system has decentralized dramatically and with little planning over the past two decades in response to lack of... |

| With the risk of the drought in the agricultural production areas of Zambia, conservation farming (CF) was introduced as a set of technologies that can improve productivity while reducing plant stress due to moisture constraints. Under animal traction, CF involves using the Magoye ripper to minimize soil disturbance in land preparation and to help improve water conservation, thus enhancing farmers’ land and labor productivity. This technology has been promoted by Golden Valley Agricultural Research Trust (GART) and other stakeholders in the agricultural sector in Zambia and shows promise in on-station and on-farm trials. This research is based on actual farmer use of the ripper in Eastern and Southern Provinces in 2004/2005, a year with erratic rainfall... |

| This study documents the long-term evolution of western African precipitation during the Last Interglacial (LIG). We compare geochemical records obtained on nine sediment cores from the western African margin to a transient simulation (130–115 ka) performed with an ocean-atmosphere general circulation model and insolation as sole forcing. Good agreement between proxy records and model outputs indicates that long-term changes in western African precipitation largely responded to insolation variations during most of the LIG. After an early LIG dry phase (related to high-latitude iceberg melting or dating uncertainties), boreal summer insolation controlled the intensification of the North African monsoon between 127 and 122 ka, perhaps facilitating human... |

| À l'initiative de l'USAID, la BAD, MSU et l’INSAH, une quarantaine de chercheurs, de décideurs politiques et d’opérateurs-terrain venus de 19 pays et représentants une vingtaine d'institutions Africaines ou internationales se sont retrouvés à Abidjan dans le cadre d'un atelier continental pour débattre sur le thème de la transformation de l'agriculture Africaine. Cet atelier a été parrainé par le Ministre de l'Enseignement Supérieur et de la Recherche Scientifique de la Côte d'Ivoire. L'atelier d'Abidjan s'est basé sur les réflexions précédentes portant sur les défis à relever (insécurité alimentaire, pauvreté, et dégradation de l’environnement) au cours du processus de stimulation de la transformation structurelle de l'agriculture en Afrique, notamment... |

| This paper discusses how impact-oriented agricultural research for development systems in Africa can be better organized and managed. Specifically, the paper puts forth the argument that achieving the development targets set by African leaders and the international community, for example, through the Millennium Development Goals, will be extremely difficult without a satisfactory re-orientation of the organization and management of African research for development systems. Such a re-orientation involves carefully linking the agricultural research agenda with national development priorities; improving coordination, interaction, interlinkages, partnerships, and networks among system agents—that is, agricultural research institutes, extension systems, higher... |

| This working paper synthesizes the theoretical and empirical literature on the use of cash transfers in response to food crisis situations, with particular attention to their use in situations that are exacerbated by volatile, often inflationary, commodity prices. The paper is designed for policymakers who are wondering if cash transfers might be an appropriate instrument in the context of 2008’s unstable commodity prices for both food and energy, but are unfamiliar with the literature and discussions surrounding the cash vs. food debate. After defining some key terms and presenting a brief review of the theory behind cash transfer use, the paper synthesizes evidence from studies that have evaluated past cash transfer programs. While the focus is on... |

| Campaigns to prevent the spread of HIV require accurate knowledge of the characteristics of those most likely to contract the disease. Studies conducted in Sub-Saharan Africa during the 1980s generally found a positive correlation between socioeconomic characteristics such as education, income, and wealth and subsequent contraction of HIV. As the disease has progressed, the relationship between socioeconomic status and HIV contraction may have changed, although there is little evidence to support this. An emerging strand of the literature on the AIDS epidemic in Africa posits that poverty is increasingly associated with the spread of the disease. However, this conclusion is somewhat contentious, as other recent studies find mixed evidence of a poverty-AIDS... |
