Seed management by small-scale farmers in Zambia. A study of cowpea, groundnut and sorghum seed in the Southern and Western Provinces (NRI Bulletin 76)

Field surveys of on-farm cowpea, groundnut and sorghum management in two regions of Zambia are described. The survey included seed saved on-farm and seed sources off-farm. Samples of seeds were collected just prior to planting and assessed for germination potential. Conclusions are given on the general status and potential for improving seed quality and on farmer seed management

Smallholder Income and Land Distribution in Africa: Implications for Poverty Reduction Strategies

This paper provides a micro-level foundation for discussions of income and asset allocation within the smallholder sector in Eastern and Southern Africa, and explores the implications of these findings for rural growth and poverty alleviation strategies in the region. Results are drawn from nationally-representative household surveys in five countries between 1990 and 2000: Ethiopia, Kenya, Rwanda, Mozambique, and Zambia. The paper addresses five major points: (1) why geographically-based poverty reduction or targeting strategies-e.g., focusing on marginal areas-is likely to miss a significant share of the poor in any particular country regardless of targeting efficiency in these areas; (2) why current enthusiasm for community-driven development approaches will require serious attention to how resources are allocated at local levels; (3) why sustained income growth for the poorest strata of the rural population will depend on agricultural growth in most countries, even though the poor generally lack the land and other productive resources to respond directly or immediately to policies and investments to stimulate agricultural growth; (4) why agricultural productivity growth, while most easily generating gains for better-off smallholder farmers, is likely to offer the best potential for pulling the poorest and land-constrained households out of poverty; and (5) why meaningful poverty alleviation strategies in many countries will require fundamental changes to make land more accessible to smallholder farmers. This could be accomplished through various processes, including improvement in land rental markets or perhaps land redistribution. We briefly elaborate on each of these findings.Food Security and Poverty, Land Economics/Use,

The evolving SARS-CoV-2 epidemic in Africa: Insights from rapidly expanding genomic surveillance

INTRODUCTION Investment in Africa over the past year with regard to severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) sequencing has led to a massive increase in the number of sequences, which, to date, exceeds 100,000 sequences generated to track the pandemic on the continent. These sequences have profoundly affected how public health officials in Africa have navigated the COVID-19 pandemic. RATIONALE We demonstrate how the first 100,000 SARS-CoV-2 sequences from Africa have helped monitor the epidemic on the continent, how genomic surveillance expanded over the course of the pandemic, and how we adapted our sequencing methods to deal with an evolving virus. Finally, we also examine how viral lineages have spread across the continent in a phylogeographic framework to gain insights into the underlying temporal and spatial transmission dynamics for several variants of concern (VOCs). RESULTS Our results indicate that the number of countries in Africa that can sequence the virus within their own borders is growing and that this is coupled with a shorter turnaround time from the time of sampling to sequence submission. Ongoing evolution necessitated the continual updating of primer sets, and, as a result, eight primer sets were designed in tandem with viral evolution and used to ensure effective sequencing of the virus. The pandemic unfolded through multiple waves of infection that were each driven by distinct genetic lineages, with B.1-like ancestral strains associated with the first pandemic wave of infections in 2020. Successive waves on the continent were fueled by different VOCs, with Alpha and Beta cocirculating in distinct spatial patterns during the second wave and Delta and Omicron affecting the whole continent during the third and fourth waves, respectively. Phylogeographic reconstruction points toward distinct differences in viral importation and exportation patterns associated with the Alpha, Beta, Delta, and Omicron variants and subvariants, when considering both Africa versus the rest of the world and viral dissemination within the continent. Our epidemiological and phylogenetic inferences therefore underscore the heterogeneous nature of the pandemic on the continent and highlight key insights and challenges, for instance, recognizing the limitations of low testing proportions. We also highlight the early warning capacity that genomic surveillance in Africa has had for the rest of the world with the detection of new lineages and variants, the most recent being the characterization of various Omicron subvariants. CONCLUSION Sustained investment for diagnostics and genomic surveillance in Africa is needed as the virus continues to evolve. This is important not only to help combat SARS-CoV-2 on the continent but also because it can be used as a platform to help address the many emerging and reemerging infectious disease threats in Africa. In particular, capacity building for local sequencing within countries or within the continent should be prioritized because this is generally associated with shorter turnaround times, providing the most benefit to local public health authorities tasked with pandemic response and mitigation and allowing for the fastest reaction to localized outbreaks. These investments are crucial for pandemic preparedness and response and will serve the health of the continent well into the 21st century

SMALLHOLDER INCOME AND LAND DISTRIBUTION IN AFRICA: IMPLICATIONS FOR POVERTY REDUCTION STRATEGIES

This paper provides a micro-level foundation for discussions of income and asset allocation within the smallholder sector in Eastern and Southern Africa, and explores the implications of these findings for rural growth and poverty alleviation strategies in the region. Results are drawn from nationally-representative household surveys in five countries between 1990 and 2000: Ethiopia, Kenya, Rwanda, Mozambique, and Zambia. The paper shows that farm sizes in most of Africa are declining over time; that farm sizes are declining at a faster rate for households at the low end of the land size distribution; that Gini coefficient measures indicate that farm sizes within the small-farm sectors are generally more inequitably distributed than in Asia and Latin America at the time of their green revolutions, not even considering the serious additional disparities in land allocation that would result if large-scale farming sectors were to be included in the several case countries having bi-modal land distribution patterns; and that the largest part of the variation in per capita farm sizes within the small-farm sectors is, in every country, predominantly within-village rather than between villages. Realistic discussions of poverty alleviation strategies in Africa need to be grounded in the context of these land distribution patterns and trends. The paper concludes by identifying the implications for poverty alleviation strategies
