The Global Warming Potential (GWP) is a measure of how much energy the emissions of 1 ton of a gas will absorb over 100 years, relative to the emissions of 1 ton of carbon dioxide (CO2). Methane (CH4) and nitrous oxide (N2O) are greenhouse gases that have the GWP of 28-36 and 265-298. Especially in paddy soil, CH4 accounts for 27% of whole anthropogenic CH4 emission in the world, and its reduction is expected to contribute to the prevention of global warming in the agricultural sector.
“Prolonged MD” (1-week longer than the local MD practice) can suppress 30% of net GWP of CH4 plus N2O without reducing the yield and quality of rice. This water management technology by “Prolonged MD” is an economically effective measure against global warming, as the additional farming costs are extremely small.
|Projected Cumulative Lives Impacted||700|
|New Implemented Countries||Brazil, Argentina, Kenya, Uruguay, Uganda, Tanzania|
|Recruit||3 management, 2 board, 1 advisor and 6 volunteer|
|New Feature||Biochar made by rice husks and straws could contribute to carbon sequestration in addition to CH4 reduction by prolonged MD water management|
Our team including already retired members continuously tackled with harmonizing GHG reduction and increasing rice production in global scale mainly monsoon Asian countries. From early 1990s, we settled measurement equipment to several developing Asian countries funded by multi stakeholders and collaborated with local farmers. Both bottom-up and top down approaches were harmonized in our activities including national government, local communities, academics in our "Prolonged MD" project.
