Impact of Water Management on Methane and Nitrous Oxide Emission Dynamics in Asian Paddy Ecosystems

With increasing demand for rice productivity linked with intense pressure on water availability in Asia, novel strategies are sought to optimise water management in paddy cultivation without compromising the yield. The conventional submerged paddy ecosystems not only consume water excessively but also constitute a major source of methane (CH4) and nitrous oxide (N2O), two highly...

Developing an economic, environmental and agronomic case for the increased use of organic amendments in South Asia

Aggressive fertilizer subsidies throughout South Asia have led to a rapid increase in the use of synthetic nitrogen fertilizers such as urea at the farm level. While this has been successful in increasing yields, significant yield gaps remain between potential and actual farm yields, while unbalanced or over application of fertilizers potentially damages soil and...
