Analysis of agricultural activities in the Better Life Alliance (BLA) project in Zambia showed potential reduction in greenhouse gas emissions (GHG), mostly (85%) due to avoided savanna degradation and conversion. The GHG impact due to BLA’s interventions is estimated at –902,531 tCO2e/yr, equivalent to saving 2,089,550 barrels of oil. BLA’s business model linked prevention of degradation and conversion of shrubland to market-based incentives for agricultural crops, thereby providing farmers with economic incentives for conservation and climate change mitigation. BLA promoted a comprehensive approach to soil fertility management. It promoted agroecological approaches such as recycling farm organic resources, planting nitrogen-fixing trees, minimal tillage, and cover crops. BLA reduced postharvest loss (PHL) through improved product processing, storage, and packaging. Changes in PHL were estimated for groundnuts (–100%), maize (–40%), rice (–80%), and soybeans (–67%), which contributed to decreases in emission intensity (GHG emissions per unit of production) for each of these products.
