Agricultural drought is a complex phenomenon with numerous consequences and negative implications for agriculture and food systems. The Sahel is frequently affected by severe droughts, leading to significant losses in agricultural yields. Consequently, assessing vulnerability to agricultural drought is essential for strengthening early warning systems. The aim of this study is to develop a new multivariate agricultural drought vulnerability index (MADVI) that combines static and dynamic factors ...

Maize is the staple food of most households in sub-Saharan Africa. The adoption of stress-tolerant maize varieties (STMV) is being promoted due to climate change. There are various methods applied to disseminate these varieties. Unfortunately, the adoption at the household level is still unsatisfactory. This study evaluated the effectiveness of the dissemination methods used in Benin. We identified dissemination methods from key informants involved in STMV seed dissemination projects. The performance ...

We analyze rural households’ purchases of food (cereals and non-cereals) in Sub-Saharan Africa using nationally representative data with 65,000 observations covering 7 countries over a decade. We distinguish between three strata of countries: lower stratum in income and urbanization, middle stratum, and upper stratum. The paper breaks ground by the breadth and time length of the sample. We find that purchases form the majority of rural food consumption whether in favorable or unfavorable agroecological ...

Much has been made of the potential for aquaculture to improve rural livelihoods and food and nutrition security in Africa, though little evidence exists to back such claims. This study, conducted in northern Zambia, assessed the benefits of adopting aquaculture by comparing a sample of households with (n = 177) and without fishponds (n = 174).

Maize is a critical staple cereal across Sub-Saharan Africa but attempts to improve its productivity in small-scale farming systems often prove disappointing. The 12 key technologies required to overcome poor yields are mostly known, but the manner that they are mobilized, packaged, and delivered requires re-evaluation. Combinations of better varieties and their necessary accompanying inputs must become more available and affordable for an African maize revolution to succeed, and land must be ...

This study evaluated the morphological diversity of some Nigerian accessions of Bambara groundnut. Field experiments were conducted in Nigeria in two locations and the phenotypic variation of Bambara groundnut accessions evaluated in 3 years (2017–2020) using a randomized complete block design. Twenty-eight quantitative and 10 qualitative traits were observed. Twenty-three out of the 28 quantitative morphological traits showed significant differences. TVSu-589 (28.85) and TVSu-670 (28.57) had the ...

Fusarium wilt caused by Fusarium oxysporum f. sp tracheiphilum (Fot) is a soil-borne fungal disease of significant constraint to cowpea production in West Africa. The disease infection can cause up to 100% yield loss in highly infested fields. The most effective control strategy is the use of resistant varieties. Sixty cowpea germplasm collections were screened for resistance to F. oxysporum. The result revealed that only two (TVu 134 and TVu 410) of the germplasm showed a high level of resistance ...

The purpose of this technology catalogue is to advance high quality cassava flour (HQCF) as a substitute for wheat in Africa. While Africa has the potential to increase its wheat production, it appears to be small in proportion to the massive demand for imported wheat. For example, Africa imported US $11 billion from eight European and North American countries in 2020, a massive expenditure of foreign reserves that could be better directed toward longer-term development goals. At the same time, ...

This study interviewed 349 poultry farmers that benefited from government poultry feed input palliatives meant to help them to contain the negative effects of COVID-19 of hunger, food insecurity, and poverty. Demographic results revealed that both males and females are involved in poultry farming; the average age of poultry farmers was 45 years, with an average family size of five. The average years of education were 13, equivalent to JSS 3 in the Nigerian education system. Types of poultry show ...
