Farmers in Vietnam burn leftover rice stalks to clear fields for the next planting season, but the practice contributes significantly to air pollution and greenhouse gas emissions. USAID launched a pilot activity to improve air quality in Vietnam by reducing this practice in Hai Duong and Hanoi through the use of enzymes as biological catalysts to convert rice stalks into organic fertilizer. This gives farmers an alternative to open burning and enriches the soil.
This work improves soil quality, reduces the expense of buying chemical fertilizers and pesticides, improves long-term productivity, and increases economic prospects for farmers while reducing air pollution and greenhouse gas emissions.
