Can biological control resolve the larger grai borer crisis? por Markham, R., Borgemeister, C., Meikle, W.

“…The accidental introduction of the lager grain borer, Prostephanus truncates, in the early 1980s result in destructive pest outbreaks in small-farm maize stores in both East and West Africa. Studies comparing the situation in rural maize stores in Costa Rica (in the pest's neotropical area of origin) with that control of natural enemies in Central America and that classical biological control of the pest in Africa might be feasible. …”

Exposure to cyanide following a meal of cassava food por Oluwole, O.S., Onabolu, A.O., Sowunmi, A.

“…Exposure to cyanide from gari, a popular cassava food in West Africa, is implicated in the causation of ataxic polyneuropathy and amblyopia, but this has been questioned because cyanide was not detected in gari in a study. …”

Varietal selection in marginal agroecological niches and cultural landscapes: the case of rice in the Togo Hills por Teeken, Béla, Temudo, M.P.

“…We contend that ― in a period of climate crisis, bio- and agrobiodiversity depletion, rapid social change and market instability ― plant breeding in West Africa must be participatory, decenter from a focus on high external input agriculture and include farmers’ varieties, better contributing to food security, quality, and nutrition, while strengthening agroecological practices.…”

Capacitating Science-Policy dialogue platforms to trigger actions for accessing climate finance: experiences and lessons learnt from Ghana, Mali and Niger por Segnon, Alcade C, Botchway, Vincent Ansah, Sogoba, Bougouna, Idrissa, Mamoudou, Moglo, Komlanvi, Samaké, Oumar, Essegbey, George Owusu, Karbo, Naaminong, Whitbread, Anthony M., Thornton, Philip K., Zougmoré, Robert B.

“…Adequate financial resources are key barriers limiting the effectiveness and sustainability of the national science-policy dialogue platforms in West Africa. This Info Note documents the outcomes of and lessons learnt from capacity building activities to science-policy dialogue platforms in Ghana, Mali and Niger and how the capacity building program empowered the platforms and/or triggered actions for accessing climate finance. …”

Bergmann's rule holds in birds inhabiting southern Guinea forests but not in the northern Savanna of Nigeria por Barshep, Y., Awoyemi, A.G., Abalaka, J., Ottosson, U.

“…We tested this hypothesis in 30 Afrotropical resident bird species inhabiting two vegetation types at different latitudes (southern guinea forests and northern savanna) and at different altitudes in Nigeria, West Africa. Using principal component analyses of body mass and wing length, the first principal component, the component of size, indicated that individuals in montane areas were larger than lowland populations in southern guinea forests. …”

An agent-based model for collaborative learning to combat antimicrobial resistance: Proof of concept based on broiler production in Senegal por Ndekou, P.P., Drake, A., Lomax, J., Dione, Michel M., Faye, A., Nsangou, M.D.N., Korir, Luke, Sklar, E.

“…Our model is presented as a flexible tool with promise for extension as part of AMR policy development in Senegal and West Africa, using participatory approaches. This work indicates that ABM can potentially play a useful role in fostering counter-AMR initiatives driven by food system actor behaviour in lower- and middle-income countries (LMIC) more generally.…”

Cocoa under heat and drought stress por Mensah, E.O., Vaast, Philippe, Asare, R., Amoatey, C.A., Owusu, K., Asitoakor, B.K., Raebild, A.

“…Cocoa (Theobroma cacao L.) is an important cash crop in many tropical countries, particularly in West Africa. Heat and drought are both known to affect the physiology of cocoa plants through reduced rates of photosynthesis and transpiration, as well as changed physiological processes such as the functions of photosystems, chlorophyll synthesis, stomatal conductance and expression of heat-shock proteins. …”

Informal cross-border trade in Africa por Bouët, Antoine, Cissé, Brahima, Traoré, Fousseini

“…We present two interesting initiatives that are intended to assess the phenomenon of ICBT in African regions: (1) an initiative coordinated by the Permanent Interstate Committee for Drought Control in the Sahel (Comité permanent Inter-État de Lutte contre la Sécheresse au Sahel, abbreviated as CILSS) and implemented by the West African Association for Cross-Border Trade in Agro-forestry-pastoral and Fisheries Products - (AOCTAH, Association Ouest Africaine du Commerce Transfrontalier des produits Alimentaires, Agro-sylvo-pastoraux et Halieutiques) that measures informal/unrecorded trade in agricultural commodities in West Africa; and (2) an initiative designed by the Uganda Bureau of Statistics (UBoS) and Bank of Uganda (BoU) which assesses informal/unrecorded trade in agricultural and industrial commodities at Uganda’s borders with its neighboring countries.…”

Assessing the relative ages of admixture in the bovine hybrid zones of Africa and the Near East using X chromosome haplotype mosaicism por Freeman, A.R., Hoggart, C.J., Hanotte, Olivier H., Bradley, D.G.

“…Extensive LD, likely to be the result of ongoing admixture, was discovered in hybrid cattle populations from the perimeter of the tsetse zone in West Africa. A Bayesian method to assign microsatellite allele ancestry was used to designate the likely origin of each chromosomal segment and assess the relative ages of admixture in the populations. …”
