What is AWD (Alternate Wetting and Drying)?

AWD is a water management technique in rice cultivation that alternates between flooding and draining to reduce greenhouse gas (methane) emissions and water usage.

J-Credit is a system where the government certifies credits for CO2 and other emissions reductions achieved through the introduction of energy-saving equipment and the use of renewable energy, as well as CO2 absorption through proper forest management.
