Production Diversity and Constraints in Smallholder Farms in the Bamboutos Mountain
International Journal of Research and Review, 2021 Smallholder farmer agricultural productivity in developing countries is more often diverse and limited by diverse constraints. For optimal agricultural production and income crops for diversification must be carefully selected and the constraints properly addressed.

Advanced Science, EarlyView.Water scarcity poses a critical threat to global food security. A low‐power, flexible electromagnetic actuator is presented for smart drip irrigation systems. The device achieves precise, wide‐range flow modulation (0.05–5.8 mL/min) in response to real‐time plant demands, reducing water consumption compared to conventional flood irrigation.
