Description
Meeting food demand in the Global South requires smallholder yield intensification. Conventional intensification using synthetic fertilizers embeds significant greenhouse gas emissions and imposes costs infeasible for resource-constrained farmers. We present results from 216 smallholder rice farmers across 42 villages in India showing a median 24.7% yield increase and over 20% increase in household income from enhanced rock weathering. This demonstrates a pathway toward intensification not dependent on synthetic fertilizers, with deployment costs offset by carbon finance.
