Climate change is considered as a major threat for agricultural production in Vietnam, particularly for coffee production, one of the most important agricultural sectors of the country. To effectively cope with the negative impacts of climate change on coffee production, the ways of understanding and also adequate responses by farmers on the climate change are very important. This paper aims to provide empirical insights into the farmers’ perception of climate change and their adaptation practices to its impacts on coffee production. The results from the questionnaire survey of 151 smallholder coffee farmers in Dak Nong province reveal the fact that the farmers understood the progress and impact of climate change through their observation into their surrounding areas. Coffee growers’ observation about the climate variability is remarkably consistent with the statistical data from the meteorological authority. However, this research revealed that their capacity to cope with climate change was relatively limited, mostly based on their own resources. This research suggests that more studies are required to examine the application of environmentally sustainable approaches to cope with climate changes.
