Editorial: Sustainable intensification of smallholder farming systems in Sub-Saharan Africa and South Asia

Résumé

Agricultural production in sub-Saharan Africa (SSA) and South Asia (SA) is mainly rainfall-dependent and dominated by smallholder farming systems. These smallholder farming systems with landholdings <5 ha produce about 80% of the food consumed in these regions (Chauvin et al., 2012; Jayne et al., 2014). Despite the contribution of the smallholder farmers to food production in these regions especially in SSA, productivity from their farms is low due to several factors such as low and declining soil fertility, limited use of external inputs, unfavorable policy, market and institutional arrangements, pests, and diseases, as well as the effects of climate change. The low productivity of agriculture among smallholder farmers exacerbates poverty levels since it is the main source of livelihood for more than 50% of the workforce in these regions (Odusola, 2021).
