Postharvest losses and mitigating technologies: evidence from Upper East Region of Ghana
Sustainable Futures, 2021 Post-harvest losses (PHL) have been identified as a crucial challenge to achieving food and nutrition security in sub-Saharan Africa. Access to reliable data and standardized methods of estimating PHL are a twin barrier to developing long term mitigation

A Model of Seasonal Savanna Dynamics
SIAM Journal on Applied Mathematics, 2023 Abstract. We introduce a mathematical model of savanna vegetation dynamics. The usual approach of nonequilibrium ecology is extended by including the impact of wet and dry seasons. We present and rigorously analyze a model describing a mixed woodland-grassland ecosystem with stochastic environmental noise in the form of vegetation ...

Genetic characterization and population structure of maize populations using SSR markers
Annals of Agricultural Sciences, 2019 Maize is a major staple food in sub-Saharan Africa. However, due to the threats posed by biotic and abiotic constraints to its production, it is a prerequisite to conserve germplasm with diverse genetic background and to seek for favourable genotypes ...

Generation mean analysis of the key earliness related traits in cowpea (Vigna unguiculata (L.) Walp)
Scientific African, 2022 The nature of gene action controlling agronomic traits enables plant breeders to execute a successful crop improvement programme. To elucidate the type of gene action governing the key earliness related traits in cowpea, seven populations of the six ...
