Alternative rice cropping systems tolerant to salinity under climate change in Vietnam

Abstract

Salinity caused by sea level rise is expected to adversely affect the sustainable development of local communities’ in the coastal areas of Vietnam by making productive lands unfit for rice cultivation. Rice is usually considered moderately sensitive to salinity. Rice farmers in Vietnam are looking for cropping systems that are more tolerant to salinity while maintain yield under the changing climate. This technical brief presents preliminary results from experiments conducted on five rice cultivars (BT7 as control) response to various levels of salts in irrigation water in Thinh Long commune and Rang Dong farm in northern Vietnam as part of ClimaViet project.
