Adaptation to climate impacts on rice production: an analysis of dry zone farmers in central Myanmar

Abstract

We explore the agroecological methods that rice farmers of Myanmar employ for adapting to climate change, the factors influencing their adaptation strategies, the extent of their adaptive capacity (AC), and the connection between AC and rice yield. We randomly selected 197 farming households in 2 villages for a community-based survey. To collect qualitative data, 7 key informant interviews and 2 focus group discussions were conducted in 2 sampled villages in Kyaukse Township, Mandalay Region. The study utilized descriptive analysis, multiple regression (MR) analysis, and an adaptive capacity index for data examination. The most practiced adaptation strategies among rice farmers with high AC included crop diversification (adopted by 98% of farmers), utilization of climate-resistant varieties (92%), and modification of planting techniques (87%). The MR analysis revealed that personal factors, such as level of education and years of agricultural practice, along with social factors, such as access to credit, irrigation, cooperative memberships, participation in training, and access to information dissemination, were significant positive determinants of the farmers’ choice of adaptation methods. Farmers with high AC were found to have a higher rice yield (4506.46 kg ha-1) compared to those with low AC (3392.56 kg ha-1). The overall AC was assessed to be at a moderate level (0.53) for farmers in these communities. It is recommended that relevant government and private entities promote community education and communication networks to foster adaptation initiatives. The improvement of irrigation and credit facilities in a systematic and strategic manner would meaningfully enhance the long-term AC of farmers.
