Vulnerability to climate change of cocoa in West Africa: patterns, opportunities and limits to adaptation by Schroth, Götz, Läderach, Peter R.D., Martínez Valle, Armando Isaac, Bunn, Christian, Jassogne, Laurence T.P.

“…We find that: 1) contrary to expectation, maximum dry season temperatures are projected to become as or more limiting for cocoa as dry season water availability; 2) to reduce the vulnerability of cocoa to excessive dry season temperatures, the systematic use of adaptation strategies like shade trees in cocoa farms will be necessary, in reversal of the current trend of shade reduction; 3) there is a strong differentiation of climate vulnerability within the cocoa belt, with the most vulnerable areas near the forest-savanna transition in Nigeria and eastern Côte d'Ivoire, and the least vulnerable areas in the southern parts of Cameroon, Ghana, Côte d'Ivoire and Liberia; 4) this spatial differentiation of climate vulnerability may lead to future shifts in cocoa production within the region, with the opportunity of partially compensating losses and gains, but also the risk of local production expansion leading to new deforestation. …”

Setting up agricultural water management interventions - learning from successful case studies in the Volta and Limpopo river basins by Bruin, A. de, Pateman, R., Barron, Jennie, Balima, M., Ouédraogo, I., Dapola, E.D., Fosu, M., Annor, F.O., Magombeyi, Manuel Simba, Onema, J.M.K.

“…In four countries within the Volta and Limpopo river basins, consultations were carried in 33 case studies of successful AWM interventions with implementing organisations and beneficiaries using a participatory GIS methodology. A systematic text analysis of 55 case study reports showed that these 33 interventions have had a positive impact on the well-being of beneficiaries and there was a sustained and wider uptake of the AWM technologies or approaches introduced. …”

Recent progress in cassava varietal improvement in China by Fang, Baiping, Lin, Xiong, Li, Kaimian, Tian, Yinong

“…There are three institutions, SCATC, UCRI and GSCRI, which are systematically working on cassava breeding in China. Since the principal constraint to cassava varietal improvement is the lack of genetic variability, the main approach currently used is the evaluation and selection of hybrid seeds introduced from CIAT/Colombia and from the Thai-CIAT program. …”
