Since oil prices’ decline in 2014, agriculture has received renewed interest in Nigeria as a key sector for achieving sustainable growth and generating foreign exchange. One of the identified obstacles to achieving these goals is the need to improve agricultural productivity. Cowpea is one of the priority crops identified for productivity improvement. Currently cowpea yields are below 900 kg/ha, but it has been shown that with the right technology, these yields could potentially double. One of the main biotic constraints for cowpea is the infestation of the insect pod borer (Maruca Vitrata). No conventional variety has been developed to resist this pest, but with the use of biotechnology and the sustained collaboration of national and international partners over many years, there is now a genetically modified pod-borer-resistant (or more generally insect-resistant) cowpea. This paper estimates the potential economic benefits of adopting this new technology and the cost that Nigeria will incur if this adoption is delayed. The analysis is conducted using an economic surplus partial equilibrium model run with the newly developed DREAMpy software, data drawn from the Nigeria General Household Survey 2015–2016, estimations using these data, and other local sources. The estimations show that if the insect-resistant cowpea is planted in 2020, the net present-value benefits for producers and consumers would be around US$350 million, 70 percent of which would be accrued by producers. The distribution of benefits by region show that Sudan-Sahel will accrue the most benefits, given the relative concentration of cowpea in this region and the estimated higher adoption rates and yield changes. Almost half of producers’ total benefit will go to large producers, who represent only 20 percent of all cowpea producers, while small producers, representing half of all cowpea producers, will receive 24 percent of the benefit. Additionally, the analysis shows that a five-year regulatory delay will decrease the estimated benefits by around 35 percent. While Nigeria already has in place a competent biosafety system that will most likely ensure that these regulatory delays will not materialize, these estimations highlight the importance of having an evidence-based, efficient, predictable, and transparent regulatory system to ensure that the expected economic benefits are realized.

This process evaluation (PE) is part of a five-year (2021–2026) impact evaluation (IE) of the use of a new pod-borer-resistant (PBR) cowpea variety in Nigeria, a project led by the International Food Policy Research Institute (IFPRI) and funded by the United States Agency for International Development (USAID). While the IE draws from a representative sample of 1,399 farmers to determine the causal impacts of the use of PBR cowpea, the PE complements the IE by exploring in detail the potential adoption of the PBR cowpea variety and the reasons for adoption or non adoption, including its potential impacts on actors throughout the value chain. A program impact pathway (PIP) is the basis of this PE. The PIP identifies how impacts emerge from program inputs, processes, outputs, and outcomes to highlight barriers and facilitators of adoption. Given that this PE was conducted before the rollout of PBR cowpea in the IE, the analysis focuses on the potential of this innovative seed to achieve positive outputs and outcomes based on the PIP. Qualitative data were gathered from eight focus group discussions with farmers and 180 semi-structured interviews conducted with farmers, extension agents, seed dealers, and cowpea traders from eight local government areas (LGAs) in the states of Adamawa and Kwara. Given that the data are qualitative, the data are not representative. However, important insights were found that can help guide the IE.

This report is the second in a series of three evaluating underexploited African plant resources that could help broaden and secure Africa's food supply. The volume describes the characteristics of 18 little-known indigenous African vegetables (including tubers and legumes) that have potential as food- and cash-crops but are typically overlooked by scientists and policymakers and in the world at large. The book assesses the potential of each vegetable to help overcome malnutrition, boost food security, foster rural development, and create sustainable landcare in Africa. Each species is described in a separate chapter, based on information gathered from and verified by a pool of experts throughout the world. Volume I describes African grains and Volume III African fruits.

Jennifer Thomson separates fact from fiction and explains why and how GM crops can help us combat poverty, starvation and disease in the developing world, in a safe and responsible way. She explains the technology and looks at the differences and similarities between genetic modification, conventional plant breeding, and natural processes such as cross pollination and mutations. There are chapters devoted to controversial issues such as food safety (for GM crops and organically grown food), patents labelling, regulations and controls, and a section dealing with frequently-asked questions. It ends with a focus on Africa and possible future developments in GM technology. Technical terms are explained and appendices provide additional information on testing for allergens, horizontal gene transfer, and international food safety assessment documents. For those who wish to explore the subject further, it also provides a list of more than 60 web sites dealing with issues related to the GM debate.

Nigeria is the largest producer of cowpea in the world and one of the highest consumers. This paper documents the challenges in cowpea production and consumption, export, and import trends in Nigeria. The critical and comparative review reveals several important insights. Cowpea is important for households and communities due to its substantial contributions to food security, nutrition, and revenue production. It plays a pivotal role in supporting various stakeholders involved in the value chain, including producers, processors, traders, and food vendors. Thus, cowpea is a crucial multipurpose crop. Although Nigeria is the largest producer of cowpea in the world, with a total production of 3.6 million tons in 2021, the demand for cowpea surpasses its supply due to factors such as the country's large population and low productivity. We describe the main challenges encountered in Nigeria's cowpea production, encompassing a range of issues such as high susceptibility to pests and diseases from planting to storage phases, low adoption of improved cowpea seed varieties, poor soil fertility, drought, and heat stress. The data suggest that low input use, low-yield varieties, and low productivity characterize the current level of cowpea production. Our findings suggest the need for tailored strategies to support the adoption of improved cowpea varieties in Nigeria to increase domestic production, adherence to quality standards, exploration of international markets for export opportunities, and ultimately, household income and improve nutritional outcomes.

The third edition of Insect Resistance Management: Biology, Economics, and Prediction expands coverage by including three new chapters on African agriculture, genetic control of pests, and fitness costs of resistance. All remaining chapters have been updated to cover key scientific findings published since 2013. The coauthors have expertise in evolutionary biology, ecology, economics, epizootiology, statistics, modeling, IPM, and genetics. The original themes demonstrating the importance of economics, IPM, pest behavior, and the behavior of humans implementing insect resistance management (IRM) are still relevant. Entomologists and others developing experiments, models, regulations, or public policy will benefit from this book that avoids reliance on dogma by analyzing and synthesizing knowledge about a wide variety of species, landscapes, and stakeholder problems. - Provides insights from the history of IRM to the latest science - Includes contributions from experts on ecological aspects of IRM, molecular and population genetics, economics, and IRM social issues - Encourages scientists and stakeholders to implement and coordinate strategies based on local and species-specific conditions
