CCAFS East Africa 2019–2021 Summary. Strategy for Supporting Agricultural Transformation, Food and Nutrition Security under Climate Change por Solomon, Dawit, Radeny, Maren A.O., Mungai, Catherine, Recha, John W.M., Schuetz, Tonya, Gadeberg, Marianne

“…Agriculture is currently the main source of national greenhouse gas (GHG) emissions in East Africa, accounting for about 46% in Uganda and about 86% in Tanzania, for example. In the face of a changing climate, effective adaptation and mitigation strategies focusing on revitalization, intensification, diversification and innovation are thus needed to sustainably transform the region’s agriculture and decouple agricultural growth from GHG emissions.…”

The development of a multiplex PCR assay for the detection of Fusarium oxysporum f. sp. cubense lineage VI strains in East and Central Africa por Ndayihanzamaso, Privat, Karangwa, Patrick, Mostert, Diane, Mahuku, George S., Blomme, Guy, Beed, Fenton D., Swennen, Rony L., Viljoen, Altus

“…The Foc Lineage VI multiplex PCR was used to identify Foc isolates collected in banana fields at five locations in Uganda and Tanzania. Foc Lineage VI DNA was detected at a concentration as low as 0.1 ng/μl, both in the absence and presence of banana DNA, and can therefore be used as an accurate diagnostic tool for Foc Lineage VI strains.…”

Drawing on data from an original survey of 1001 rural farm households across five study sites, we find that women, on average, have fewer connections to experts and farmers’ groups than men but are relatively better connected in farmer-to-farmer social networks across different farming systems. …”
