Determinants of crop residue use along an intensification gradient in West Africa's Savannah zones por Akinola, Adebayo A., Abdoulaye, Tahirou, Valbuena, Diego, Erenstein, Olaf, Haileslasie, A., Germaine, I., Shehu, M., Ayedun, B.

“…However, as household size (p<O.Ol) increased the· probability of enhancing internal services to agricultural systems declined. This suggests that larger households with more pressing demands for cash tend to sell their crop residues at the expense of more sustainable uses such as mulching. …”

Contribution of nutrient diversity and food perceptions to food and nutrition security among smallholder farming households in Western Kenya: a case study por Ng'endo, Mary, Bhagwat, S., Keding, G.B.

“…Sub-Saharan Africa is the only region in the world where hunger is prevalent in over one-third of the population, with smallholder farming households, producers of over 80% of Africa’s food, facing both calorie and micronutrient deficiencies. With agricultural systems serving as the main source of all nutrients, little is known about the extent to which agricultural diversity in different seasons can meet macro- and micronutrient needs in rural Africa.Linkages between nutrient diversity and food species were investigated.A case study was conducted in Western Kenya to assess the seasonal nutrient diversity, seasonal nutrient accessibility levels, and food perceptions in 30 smallholder farms, 7 markets, and among 97 focus group discussion participants, respectively. …”

Agricultural diversification as an important strategy for achieving food security in Africa por Waha, Katharina, Wijk, Mark T. van, Fritz, Steffen, See, Linda, Thornton, Philip K., Wichern, Jannike, Herrero, Mario

“…Forty three percent of the African cropland lacks these opportunities at present which may hamper the ability of agricultural systems to respond to climate change. While sustainable intensification practices that increase yields have received most attention to date, our study suggests that a shift in the research and policy paradigm towards agricultural diversification options may be necessary.…”

Transformation in Practice: A Review of Empirical Cases of Transformational Adaptation in Agriculture Under Climate Change por Vermeulen, Sonja J., Dinesh, Dhanush, Howden, S. Mark, Cramer, Laura K., Thornton, Philip K.

“…Our review provides little early evidence that transformative adaptation processes in response to climate change have generated more resilient agricultural systems or improvements in governance. Governments and development partners could improve the effectiveness of outcomes through providing more comprehensive and long-term approaches to adaptation planning alongside financial and technical assistance, within a framework that rewards farms as multi-functional systems.…”
