On-farm diversification is a promising strategy for farmers to adapt climate change. However, few recommendations exist on how diversify farm systems in ways that best fit the agroecological and socioeconomic challenges face. Farmers’ ability adopt strategies often stymied by their aversion risk, loss of local knowledge, limited access agronomic market information, this especially case smallholders. We outline seven steps practitioners researchers agricultural development can work with...

By combining single nucleotide polymorphisms (SNPs) based data passport information, we investigated structure wild domesticated peppers, tracing back to routes evolution providing model annuum distribution, which reflects human trade historical/cultural influences. Our results highlight west–east expansion, shedding light on...
As climate changes in sub-Saharan Africa (SSA), Africa's "forgotten" food crops offer a wide range of options to diversify major staple production as key measure toward achieving zero hunger and healthy diets. So far, however, these forgotten have been neglected SSA's climate-change adaptation strategies. Here, we quantified their capacity adapt cropping systems staples maize, rice, cassava, yams changing climates for the four subregions West, Central, East, Southern Africa. We used...
For most crops, like Capsicum, their diversity remains under-researched for traits of interest food, nutrition and other purposes. A small investment in screening this a wide range is likely to reveal many traditional varieties with distinguished values. One objective study was demonstrate, Capsicum as model crop, the application indicators phenotypic geographic effective criteria selecting promising genebank accessions multiple uses from crop centers diversity. second evaluate expression...
