Gender relations and women's empowerment in small-scale irrigated forage production in Ethiopia.

Small-scale cultivation and irrigation of planted forages can increase the availability of good-quality animal feed in smallholder farms. However, low adoption rates of improved forage technologies in most parts of sub-Saharan Africa have been observed and are partly attributed to limited understanding of gender dynamics in the context of production and utilization of planted forages. The introduction of small-scale cultivation and irrigation of planted forages is likely to interlink gender relations in the mixed crop-livestock farming system given the differences in contributions, benefits and challenges men and women farmers face.

The adoption non-adoption dichotomy: Why do smallholder producers dis-adopt improved chicken breeds?

Adopting agricultural technologies is crucial to improve productivity and livelihoods in developing countries. While much research has focused on adoption decisions, understanding dis-adoption, when farmers stop using technology, is equally important. Studies on agricultural technology adoption often treat dis-adopters (those who initially adopted but later discontinued to use) and never-adopters (those who never adopted) as the same, using binary models to analyze farmers' decisions.
