Analysis of potential mitigation in the
development project Accelerating Agriculture
Productivity Improvement (AAPI) in Bangladesh
showed a 2% reduction in greenhouse gas
(GHG) emissions, driven by urea deep
placement (UDP) and alternate wetting and
drying (AWD) in flooded rice systems. Given
high emissions associated with conventional
irrigated rice production, this represents a
substantial reduction in emissions.
AAPI promotes UDP, a fertilization practice
known to increase nitrogen uptake efficiency.
Based on the project plan and progress of
implementation, UDP adoption was anticipated
on 1.1 million ha of aman rice and 700,000 ha of
boro rice. UDP is an example of the absolute
emission reductions that are possible when a
practice is widely implemented.
AAPI promotes AWD, an irrigation practice for
rice that reduces the amount of water used and
results in decreased emissions. AAPI tested
AWD on a pilot scale (21,000 ha). Climate
change mitigation benefits would increase
dramatically if adoption of AWD were more
widespread.
Due to increased rice yields, UDP and AWD
reduce the emission intensity (CO2e emitted per
kg production) from rice production by 10–48%
