Book Description
This analysis explores the relationship between agricultural R&D investments and rural poverty reduction, and the prevalence of undernourishment in sub-Saharan Africa (SSA). It uses a panel data set of internationally comparable poverty dis-aggregated by urban and rural areas, country level undernourishment, and ASTI data on R&D investments and derived indicators. The study uses agricultural R&D knowledge stocks (KS) to account for the lagged effects of research through depreciation and gestation period of investments, and applies causal mediation analysis to assess the impact of KS on poverty and hunger and measure the relative contribution of KS-induced agricultural productivity growth on those outcomes. Evidence suggests that, while SSA growth in KS has been relatively slow, it helped reduce rural poverty and undernourishment – the percentage point reduction in rural extreme and moderate poverty of a 1% annual increase in KS is 0.218 and 0.146 percentage points per year, respectively. Mediation analysis indicates that a fifth of the KS effect on extreme rural poverty, and a quarter of the KS effect on moderate rural poverty, can be attributed to KS driven gains in agricultural labor productivity. Likewise, KS growth reduces undernourishment – a 1% annual increase in KS leads to a drop of 0.132 percentage points per year in the prevalence of undernourishment, with about 40% of that effect mediated through gains in agricultural land productivity. These results indicate that KS supports poverty and hunger reduction through benefits on-farm and beyond it. They also suggest that there is room for strengthening the role of R&D KS productivity enhancing innovations. Given the current low levels of investments in R&D and resulting KS, increasing its levels will be critical, but that alone is not sufficient. Policy makers will have to rethink the way the innovations from R&D get scaled up and pay attention to the necessary complementary policies and investments that enable a sustainable pathway leading to greater productivity growth and development impacts.

Book Description
This paper looks at the prioritization of agricultural value chains (VCs) for the allocation of R&D resources that maximize development outcomes (poverty, growth, jobs, and diets). Considering that growth in VCs affects those various outcomes differently, as expansion pathways result in the diverse use of production factors and inputs, trade-offs from linkages across sectors, and changes throughout the agri-food system, this analysis uses (i) the RIAPA dynamic computable general equilibrium model to identify which agricultural VCs, when expanded through TFP growth, provide the strongest effects on the development outcomes of interest; (ii) the perpetual inventory model (PIM) to represent the lagged effect of research through knowledge stocks of agricultural R&D investments; and (iii) information on the elasticities of VC agricultural activity TFP with respect to agricultural R&D knowledge stocks, to discuss the VC priority allocations of R&D resources in Senegal. Results indicate that no one VC (crop- or livestock-related) is the most effective at improving all development outcomes. When accounting for policy preferences that attribute relative priority weight to development objectives, results (based on a ranking scale) indicate that R&D investments for maximizing development objectives can be most effective in Senegal’s VCs for traditional export crops (growth, diets, jobs, and to some extent poverty), groundnuts (poverty, diets, and jobs), rice (poverty and jobs), poultry/eggs (diets and jobs), sorghum/millet (poverty and growth), and cattle (diets and growth). Other promising VCs with potential effects at scale if strategically targeted include vegetables (poverty, diets, and jobs), oilseeds (poverty and growth), and fruits (diets and jobs). While these results can inform strategies aimed at improving multiple development outcomes, future modeling needs to focus on deepening the standardization and integration of R&D investments costs into the framework, disentangle the relevance of different types of R&D investments sources, and bring together other factors and complementary agrifood system investment dimensions relevant to sustainable and inclusive agricultural VC growth.

Book Description
The relative contribution of a sector to poverty reduction is shown to depend on its direct and indirect growth effects as well as its participation effect. The paper assesses how these effects compare between agriculture and non-agriculture by reviewing the literature and by analyzing cross-country national accounts and poverty data from household surveys. Special attention is given to Sub-Saharan Africa. While the direct growth effect of agriculture on poverty reduction is likely to be smaller than that of non-agriculture (though not because of inherently inferior productivity growth), the indirect growth effect of agriculture (through its linkages with nonagriculture) appears substantial and at least as large as the reverse feedback effect. The poor participate much more in growth in the agricultural sector, especially in low-income countries, resulting in much larger poverty reduction impact. Together, these findings support the overall premise that enhancing agricultural productivity is the critical entry-point in designing effective poverty reduction strategies, including in Sub-Saharan Africa. Yet, to maximize the poverty reducing effects, the right agricultural technology and investments must be pursued, underscoring the need for much more country specific analysis of the structure and institutional organization of the rural economy in designing poverty reduction strategies.

Book Description
What are the challenges and action points for agricultural sustainability in Sub-Saharan Africa? This open access collection of papers offers technical analyses, policy recommendations and an overview of success stories to date. Each carefully selected paper provides valuable insights for improved policy making and defines relevant strategic priorities on Africa’s sustainable transformation process, which is in line with the international development agenda. Although agriculture remains the main source of income for Africa’s population, the sector is rain-fed subjecting it to the vagaries of weather and climate change. This volume demonstrates the rationale of developing a competitive, inclusive and sustainable agribusiness sector for Africa’s food security and structural transformation. From the impact of Bioenergy crop adoption and Drought Index Insurance to Agro-Industrialization, this volume is important reading for individual researchers, academic associations and professional bodies interested in African agricultural development.

Book Description
Although Rwanda has made considerable progress in recovering politically and economically from the devastating effects of the 1994 genocide, the poverty rate is still higher and the gross domestic product lower than before the genocide. Poverty reduction and economic growth would receive much-needed support from increased agricultural growth. This study assesses alternative agricultural development strategies, identifying areas in which policy reforms, together with public and private investment, can best promote Rwandan agriculture. The authors evaluate the potential of several different agricultural subsectors-grains, root crops, livestock, and others-to contribute to national agricultural growth and poverty reduction. They conclude that growth in staple crops, particularly root crops such as cassava and potatoes, has the greatest potential to encourage economywide growth and poverty reduction. Promoting the necessary staple crop growth will require the allocation of public resources to the agricultural sector to increase significantly, reaching 10 percent of the total government budget. It will also require rethinking Rwanda's earlier emphasis on promoting export crop growth, which has proved inadequate in encouraging poverty reduction while also posing environmental problems. This study makes an important contribution to the debate over the most effective development strategies for Rwanda and other Sub-Saharan African nations.Show More Show Less
