Agricultural Development and Value Chain Enhancement Activity II in Ghana: Climate change mitigation co-benefits from sustainable intensification of maize, soybean, and rice

Published on
 

An analysis of the potential climate change
mitigation impact of the project entitled
Agricultural Development and Value Chain
Enhancement Activity II (ADVANCE II) in Ghana
shows that an approximate reduction in
greenhouse gas (GHG) emissions of 100% will
be possible. When project targets are achieved,
ADVANCE II will transform the project area from
a low net source of GHG emissions to roughly
carbon neutrality. *
 ADVANCE II is estimated to achieve moderate
GHG mitigation benefits that are driven by soil
management improvements (-9,223 tCO2e/yr),
crop residue burning reductions (-4,249
tCO2e/yr), and alternate wetting and drying
(AWD) of irrigated rice (-858 tCO2e/yr).
 The moderate increase in fertilizer and pesticide
use supported by the project leads to small
increases in GHG emissions (1,244 tCO2e/yr
and 2,514 tCO2e/yr respectively).
 ADVANCE II provides important benefits for low
emission development (LED) by significantly
reducing the crop GHG emission intensity (GHG
emissions per unit of production). This is
achieved mainly through strong growth in
agricultural productivity and reductions in
postharvest losses.
