Gendered trends in commercializing and diversifying smallholder farming systems in East Africa]Intensifying inequality? Gendered trends in commercializing and diversifying smallholder farming systems in East Africa

As the sustainability of agricultural citizen science projects depends on volunteer farmers who contribute their time, energy and skills, understanding their motivation is important to attract and retain participants in citizen science projects. The objectives of this study were to assess 1) farm...

Crop adaptation to climate change requires accelerated crop variety introduction accompanied by recommendations to help farmers match the best variety with their field contexts. Existing approaches to generate these recommendations lack scalability and predictivity in marginal production environm...


Etten, Jacob vanSousa, K. deAguillar, A.Barrios, M.Coto, A.Dell'Acqua, M.Fadda, CarloGebrehawaryat, Y.Gevel, J.M.J. van deGupta, A.Kiros, A.Y.Madriz, B.Mathur, P.Mengistu, D.K.Mercado, L.Mohammed, J.N.Paliwal, A.Pe`, M.E.Quirós, C.F.Rosas, J.C.Sharma, N.Singh, S.S.Solanki, I.S.Steinke, J.[Crop variety management for climate adaptation supported by citizen science]Crop variety management for climate adaptation supported by citizen science

Rapid climatic and socio-economic changes challenge current agricultural R&D capacity. The necessary quantum leap in knowledge generation should build on the innovation capacity of farmers themselves. A novel citizen science methodology, triadic comparisons of technologies or tricot, was implemen...

Over the last decades, participatory approaches involving on-farm experimentation have become more prevalent in agricultural research. Nevertheless, these approaches remain difficult to scale because they usually require close attention from well-trained professionals. Novel large-N participatory...
