Maize is an important food and feed crop for smallholder farmers in Vietnam affected by changing growing management conditions under ongoing climate change posing potential production risks the future. This study analyses future maize Northern based on seven main agrometeorological indicators applying indicator software (AGRICLIM) projections one global circulation model with embedded regional two emission pathways (RCP4.5 RCP8.5) from 1951 towards 2100. The results were analyzed four time slices annual, seasonal, monthly scales reveal that three local seasons (winter, spring, forage season) general become more extreme compared to current conditions. In particular, calculated increase heat stress days, heavy precipitation events, drought days show different trends specific seasons. For example, may occur frequently during spring season while risk soil erosions N-leaching rise winter season. These findings will support development of adaptation options adverse weather systems Vietnam.
