Vietnamese farmers' perception of climate change effects on water resources and determinants of climate change

This study investigates crop farmers' perception on climate change effects on water resources and factors that influence their perceptions of it in Vietnam. A sample of 253 was randomly selected from a total population of 685 crop farmers and a structured questionnaire was created to gather data. Descriptive and inferential statistics were used. The research results showed that climate change effects on water resources varied by landform. A majority of farmers perceived that: shifts in rainfall amount and variability affect the operation of runoff water and groundwater recharge; shifts in temperature level and variability considerably influence evapotranspiration; and changes in runoff amount and runoff variability greatly influence soil water storage and groundwater. Mixed cropping systems, use of soil conservation, extension contacts, farming practices, non-agricultural activities, credit programme participation, information and communication technology (ICT) owned, and education level are the important determinants of farmers' perceptions on climate change.
