Reframing women’s empowerment in water security programmes in western Nepal by Leder, Stephanie, Clement, Floriane, Karki, Emma

“…However, the vast majority of water security interventions using the term are apolitically and technically framed and fail to understand complex intersectional inequalities. We suspect that many of these interventions have been implemented following a business-as-usual approach with the risk of reproducing and even exacerbating existing gendered inequalities in access to and control over water. …”

Pathogen resistant genetically engineered crops in Africa by Tripathi, L., Kumar, P. Lava, Patil, B.L., Fatokun, C.A.

“…Genetic enhancement through transgenic technology is also being used to develop disease resistant cultivars in situations where conventional breeding is difficult or disease resistance is unavailable in the crop’s gene pool.Many of the on-going initiatives ondisease resistant genetically engineered (GE) crops in Africa have been targeting pathogens of high economic importance (e.g., banana bacterial wilt, cassava brown streak, cassava mosaic, and maize streak) affecting smallholder farmers; they are publicly funded and GE technology is offering promising solution against some of the most important diseasesthat include banana bacterial wilt, cassava brown streak, sweet potato virus complex and others. Disease resistant GE crops are yet to be released for farmer cultivation, but confined field trials are in progress in a number of countries. …”
