Abstract

     Maize has become the second most important crop after rice in Vietnam, particularly it is main cash crop for farmers in the Northwest region. To seek a solution for adapting to climate change, the impact of climate change on maize production needs to be analyzed. The AquaCrop model was used here to predict maize yield inresponse to climate change. The model was calibrated and validated for maize production at field scale in Muong Lum commune, Yen Chau district, Son La province during the period of 2008 - 2012. The AquaCrop model application under climate change scenario B2 shows that maize yield has a positive response to climate change with a predicted increase of 2.2% in 2100 compared to the period of 2008 - 2012. It recommends that maize production can be continued in the study area.
