Abstract
Maize has become the second most important crop after rice in Vietnam, particularlyit is main cash crop for farmers intheNorthwest region. To seek a solutionforadapting to climate change, the impact of climate change onmaize production needs to be analyzed. The AquaCrop model was usedhereto predict maize yield inresponse toclimate change. The model was calibrated and validated for maize production at field scale in Muong Lum commune, Yen Chau district, Son La province duringtheperiod of 2008 - 2012.The AquaCrop model application under climate change scenario B2 shows that maize yield hasapositive response to climate change with apredicted increase of 2.2% in 2100 compared totheperiod of 2008 - 2012. It recommends that maize production can be continued in the study area.
