Influence of Climate Change Impact on Agricultural Risks in Myanmar’s Dry Zone
Author: Thanda Kyi
Myanmar has wide range of climatic condition favoring the domestication of numerous crop species. The climate is mainly tropical but is sub-temperate in areas like hills and plateaus. While rice is the staple food crop of the country, field crops are also common in most areas. The well-irrigated areas in the central plain are well suited for rice, oil seeds and other cash crops. Precipitation under monsoonal influence is now very erratic and thus mean annual precipitation is often fluctuating. The irregularity of monsoonal rain follows five distinct patterns: early onset of monsoon, late onset of monsoon, break in monsoon, early departure of monsoon and late departure of monsoon. This monsoonal behavior, which causes varying, amounts of precipitation in various parts of the country, determines crops production in particular years.
There are still many uncertainties in the climate changing scenarios, and several constraints and limitations are identified. At the primary stage, however, adaptation to climate change could be approached by intensifying the conservation of drought resistance varieties; by improving crop varieties to drought tolerant types; by improving cropping practices to conserve water, intensifying on multiple and mixed cropping and by promoting crop diversification.
