Feeding the World in a Changing Climate: An Adaptation Roadmap for Agriculture por Loboguerrero Rodriguez, Ana María, Birch, James, Thornton, Philip K., Meza, Laura, Sunga, Ishmael, Bong, Bui Ba, Rabbinge, Rudy, Reddy, Matthew, Dinesh, Dhanush, Korner, Jana, Martínez Barón, Deissy, Millan, Alberto, Hansen, James, Huyer, Sophia, Campbell, Bruce M.

“…In 2017, according to the UN Food and Agriculture Organization (FAO), droughts, floods and delayed growing seasons helped trigger food crises in Central America, East and West Africa, and parts of Asia. Yet far worse outcomes are likely ahead for vulnerable food consumers and producers as these climate change impacts intensify and the world’s population climbs—if we persist with a business as usual approach. …”

An EST-SSR based genetic linkage map and identification of QTLs for anthracnose disease resistance in water yam (Dioscorea alata L.) por Bhattacharjee, Ranjana, Nwadili, C.O., Saski, C.A., Agre, A.P., Scheffler, Brian E., Augusto, J., López Montes, Antonio José, Onyeka, J.T., Kumar, P. Lava, Bandyopadhyay, Ranajit

“…QTL localization was based on phenotypic data collected over a 3-year period of inoculating the mapping population with the most virulent strain of C. gloeosporoides from West Africa. Using the mean permutation value of LOD scores as threshold value for declaring a putative QTL on all linkage groups, one QTL was consistently observed on linkage group (LG) 14 in all the three years and average score data. …”

Development of Metarhizium spp. for the control of locusts and grasshoppers por Lomer, C.J., Prior, C., Kooyman, C.

“…In the LUBILOSA programme, surveys for pathogen isolates revealed a morphologically distinctive Metarhizium flavoviride Gams and Rozsypal attacking acridoids in West Africa, Madagascar, and elsewhere. Metarhizium anisopliae (Metschnikoff) Sorokin isolates with virulence to acridoids were also obtained, including several from non-orthopteran hosts. …”

Mucuna spp. suppresses speargrass (Imperata cylindrica) and increases maize yield por Akobundu, I.O., Udensi, U.E., Chikoye, David

“…Raeuschel, is a serious weed, threatening crop productivity in smallholder farms in West Africa. Since the use of more effective practices such as deep tillage and chemical control is beyond the means of resource-poor farmers who carry out most agricultural activities in this region, low-input alternative technology needs to be developed. …”

Unravelling drivers of high variability of on-farm cocoa yields across environmental gradients in Ghana por Asante, Paulina, Rozendaal, Danae, Rahn, Eric, Zuidema, Pieter A., Quaye, Amos, Asare, Richard, Läderach, Peter R.D., Anten, Niels

“…CONTEXT: Cocoa (Theobroma cacao L.) is one of the world’s most important agricultural commodity crops with the largest share of global production concentrated in West Africa. Current on-farm yields in this region are low and are expected to decrease in response to climate change, through warming and shifts in rainfall. …”

Research progress on greenhouse gas emissions from livestock in sub-Saharan Africa falls short of national inventory ambitions por Graham, Michael, Butterbach-Bahl, Klaus, Toit, C.J.L. du, Korir, Daniel, Leitner, Sonja, Merbold, Lutz, Mwape, A., Ndung'u, Phyllis W., Pelster, David E., Rufino, Mariana C., Weerden, Tony John van der, Wilkes, A., Arndt, Claudia

“…In general, the largest data gaps included information for manure (quantity, quality, management), small ruminants, agropastoral/pastoralist systems, and in general from West Africa. Future research should focus on filling major data gaps on locally appropriate mitigation interventions and improving livestock activity data for developing Tier 2 GHG inventories in SSA. …”
