A GEOGRAPHICAL ANALYSIS ON THE EFFECTS OF DAMS ON IRRIGATED AREAS IN DAIK-U TOWNSHIP
Abstract
- Myanmar is predominantly agricultural- based and paddy being the staple food of the country, is grown both under rain fed and irrigation conditions. Pyinpon ,Bawni ,Kawliya and Bindar dams and its irrigated area are distributed in Daik-U Township providing summer paddy. The aims of this paper are to present the summer paddy cultivation conditions and soil fertilizer decreasing and other effects on summer paddy land of the study area. The average sown area of summer paddy was 4481 hectares in the study area within 10 year period from 2007-08 to 2017-18 that irrigated by the above mentioned four dams. SWOT analysis method is used to know the details of positive and negative impacts of irrigated area. Based on 242 responds in 22 village tracts of summer paddy cultivation, the positive and negative effects of dams irrigated area can be found in study area. These effects irregularly distribute within each dam and irrigated area. Although Bindar dam and its irrigated area is the largest size among all dams, negative impact on soil salinity and alkaline, waterlogging of this dam is very low. But, the use of fertilizers and pesticides are a little more than other dams. Positive effect of Bindar dams as increasing summer paddy cultivated area and food production is higher than other dams. After finding the negative and positive effect of these four dams, the solutions for these effects are sought out.
