Animal board invited review: Animal source foods in healthy, sustainable, and ethical diets - An argument against drastic limitation of livestock in the food system por Leroy, F., Abraini, F., Beal, T., Dominguez-Salas, Paula, Gregorini, P., Manzano, P., Rowntree, J., Vliet, S. van

“…When well-managed, livestock farming contributes to ecosystem management and soil health, while delivering high-quality foodstuffs through the upcycling of resources that are otherwise non-suitable for food production, making use of marginal land and inedible materials (forage, by-products, etc.), integrating livestock and crop farming where possible has the potential to benefit plant food production through enhanced nutrient recycling, while minimising external input needs such as fertilisers and pesticides. …”

Indigenous African orphan legumes: potential for food and nutrition security in SSA por Abberton, Michael T., Paliwal, R., Faloye, B., Tchamba, Marimagne, Azeez, M., Oyatomi, Olaniyi

“…These crops, particularly legumes, have the potential to improve food and nutrition security in SSA due to their cultural linkage with the regional food habits of the communities, nutritionally rich food, untapped genetic diversity, and adaptation to harsh climate conditions and poor marginal soils. Despite the wide distribution of orphan legumes across the landscape of SSA, these important crop species are characterized by low yield and decreasing utilization due in part to a lack of improved varieties and a lack of adequate research attention. …”

Model-based evaluation of rainfed lowland rice responses to N fertiliser in variable hydro-edaphic wetlands of East Africa por Grotelüschen, Kristina, Gaydon, D.S., Senthilkumar, Kalimuthu, Langensiepen, M., Becker, M.

“…Consequently, N fertiliser use was generally profitable in both wetlands, with value/cost ratios ≥ 4 and marginal rates of returns > 150%. Profitable N rates in all years were 30–120 kg ha-1 in the fringe and 30–90 kg ha-1 in the middle positions of the floodplain, and 60–150 kg ha-1 in the mid-valley and 90–150 kg ha-1 in the valley-bottom positions of the inland valley. …”

Information exchange patterns and technology adoption behavior of cattle farmers in the Colombian Amazon por Lienert, Anja, Lippert, Christian, Burkart, Stefan

“…While several studies have analysed the cattle sector in Caquetá and have identified key adoption barriers, such as poor access to finance, inputs, technical assistance, and knowledge, the importance of interconnections, and information exchange between different actor groups in facilitating innovation diffusion, has received only marginal attention. There is a broad consensus that the structure and composition of social networks can affect information flows, learning processes, capabilities, preferences, and decision-making processes and that social networks can both facilitate and impede access to information. …”
