The need for agricultural research resources in the developing world cannot be underestimated, but the availability of such resources is often poor due to lack of funding and investment. In order for Africa and other such developing countries to achieve productivity in agriculture - vital to food security, poverty reduction and sustainable management of natural resources - investment and policy development needs to be assessed. This book, a joint effort from IFPRI, ILRI and the Kellogg Foundation, explores the importance of impact assessment studies in Africa, and assembles important evidence to pave the way for further, much needed investment in agricultural research all over the developing world.

Africa is the most food-insecure continent in the world, according to the World Bank and the United Nations Food and Agricultural Organization. While low purchasing power is the main cause of food insecurity, inefficient domestic food production is also a major constraint. Our study specifically focused on four food production issues in Africa, namely, agricultural productivity, cropland use, food demand and welfare analysis, and demand-led crop breeding. First, we assessed the impact of public spending on agricultural productivity in Africa. We estimated the effect of two government-spending measures: Agriculture Budget Share (BS) and Research Share of Agricultural GDP (RS) on agriculture total factor productivity growth (TFPG). We used a panel fixed-effect estimator to control for the country-specific characteristics of twenty-eight African economies from 1991-2012. Although North African economies appeared to have the highest TFPG, this did not translate into the highest agricultural and research budget share. Meanwhile, Central African economies exhibited the lowest BS and RS, along with the lowest TFPG of the continent. The panel fixed-effect estimator revealed a marginal impact of 6.77% for RS on TFPG after seven years. However, the cumulative marginal impact of BS on TFPG is estimated at 7.21% over the eight years that follow the budget increment. Our findings suggest that a BS of 14% and a RS of 15% are required for a country to double its TFPG in the eight following years. Therefore, additional, and continuous investment in research and development is required for a significant productivity enhancement, especially in Sub-Saharan Africa. Second, we assessed the factors that shape cereal cropland allocation decisions in Nigeria and Niger. We theoretically derived the key cropland allocation arguments using the household model. Next, we used the World Bank LSMS-ISA data to map acreage mean centers and fit a fractional regression model using the panel fixed-effect estimator. We assessed the traditional Mendelsohn land use model and uncovered its limitation in efficiently approximating cereal cropland allocation. We improved the appropriateness of fit of the traditional Mendelsohn model by controlling for additional factors, such as food prices, socio-demographics, and food trade factors. Overall, we found cereal acreage shares in Nigeria and Niger to be spatially heterogeneous and determined by climatic, price, and trade factors. Additionally, farmers tend to base their cropland allocation decisions upon the price of the most important staples: maize in Nigeria; millet and sorghum in Niger. Furthermore, due to their tolerance to heat and drought, sorghum and millet compete for northeast farmland in both countries, especially for rainfed croplands. Thus, our study illustrates that millet and sorghum are key choices in ensuring food security in the context of global warming and rainfall instability. Our findings fill a literature void and provide policy makers with evidence to foster geo-referenced farmer cooperatives aimed at enhancing food production. Furthermore, our findings could be incorporated into a land use framework for planning, environmental monitoring, scenario analysis, and impact assessment. The third essay analyzed the staple foods consumption patterns of households in Niger by estimating a complete demand system. Demand elasticities are estimated using the Niger 2011 and 2014 LSMS-ISA household survey data to fit the modified Linear AIDS model. The results indicated that food consumption patterns in the country are affected by income and prices, as well as by socio-economic and geographic factors. All food items have positive expenditure elasticities and negative own-price elasticities, with rice exhibiting the most elastic demand. We found millet to be a necessity while rice and sorghum are luxuries. Additionally, our analysis revealed that urban households had a more diversified staple demand pattern. Furthermore, the welfare analysis revealed that an increase of millet price reduces rural welfare more than an increase in sorghum price. On the other hand, a sorghum price increase adversely affects the welfare of urban households the most. For example, a 20% increase of the millet or sorghum price reduces the average household welfare by 5.88% and 4.38%, respectively. This study highlights the importance of estimating staple food demand elasticities for both research and policymaking during a food price shocks. Our findings revealed that millet price is the canal that might foster support programs targeting the poorest households in Niger. Our fourth and last essay is a theoretical argument for demand-led breeding in a small-scaled farming system. Our investigation stems from the fact that agricultural productivity lags in small-scaled farming in Sub-Saharan Africa. While inadequate production capital, water control and poor infrastructure remain important challenges, the low adoption of improved and high-yielding varieties is a key limiting factor for productivity enhancement. Often, studies elucidating improved technology implementation are focused upon the adoption (demand) rather than the creation (supply). In this analytical essay, we reviewed theoretical causes and solutions to low varietal uptake for sorghum. Consistent with much of the structural research framework, we presented asymmetric information, bounded rationality, and weak intellectual property as key causes of seed market coordination failure. Leaning on the technology adoption under uncertainty model, we showed how market-induced uncertainty, compounded with other factors, reduces farmers' willingness to trade traditional seeds for improved ones. Furthermore, we used the matching theory, supported with a general equilibrium model, to show how consumer preference drives farm-level adoption. We argued that breeding programs can benefit from effective preference matching across the food value chain while leveraging on the growing demand-led breeding literature. Finally, we presented hypotheses that can be empirically used to assess stakeholders' weigh and ranking of varietal attributes across the food value chain.

This book focuses on food security and safety issues in Africa, a continent presently challenged with malnutrition and food insecurity. The continuous increase in the human population of Africa will lead to higher food demands, and climate change has already affected food production in most parts of Africa, resulting in drought, reduced crop yields, and loss of livestock and income. For Africa to be food-secure, safe and nutritious food has to be available, well-distributed, and sufficient to meet people’s food requirements. Contributors to Food Security and Safety: African Perspectives offer solutions to the lack of adequate safe and nutritious food in sub-Saharan Africa, as well as highlight the positive efforts being made to address this lack through a holistic approach. The book discusses the various methods used to enhance food security, such as food fortification, fermentation, genetic modification, and plant breeding for improved yield and resistance to diseases. Authors emphasize the importance of hygiene and food safety in food preparation and preservation, and address how the constraints of climate change could be overcome using smart crops. As a comprehensive reference text, Food Security and Safety: African Perspectives seeks to address challenges specific to the African continent while enhancing the global knowledge base around food security, food safety, and food production in an era of rapid climate change.

A changing climate is likely to have a drastic impact on crop yields in Africa. The purpose of this book is to document the effects of climate change on agriculture in Africa and to discuss strategies for adaptation to hotter weather and less predictable rainfall. These strategies include promoting opportunities for farmers to adopt technologies that produce optimal results in terms of crop yield and income under local agro-ecological and socioeconomic conditions. The focus is on sub-Saharan Africa, an area that is already affected by changing patterns of heat and rainfall. Because of the high prevalence of subsistence farming, food insecurity, and extreme poverty in this region, there is a great need for practical adaptation strategies. The book includes empirical research in Ethiopia, Kenya, South Africa, Tanzania, and other Sub-Saharan countries, and the conclusion summarizes policy-relevant findings from the chapters. It is aimed at advanced students, researchers, extension and development practitioners, and officials of government agencies, NGOs, and funding agencies. It also will provide supplementary reading for courses in environment and development and in agricultural economics.
