Ảnh hưởng của xâm nhập mặn đến công tác quản lý nguồn tài nguyên nước trong sản xuất nông nghiệp tại huyện Long Phú, tỉnh Sóc Trăng

Abstract

Saline intrusion has greatly expanded in the Vietnamese Mekong Delta in the recent years causing negative impacts on agriculture in coastal areas and leading to challenges for water resources management. This study was conducted to evaluate the effectiveness of surface water and groundwater resources management for agriculture cultivation in early 2016 in the Long Phu district, Soc Trang province. Descriptive statistic and individual interview (with farmers and managers) approaches were applied in this study. The obtained results showed that saline intrusion caused difficulties for distributing water resources, especially insufficient freshwater supply for the 3rd (Spring – Summer) rice crop in early 2016. In addition, the prolonged drought led to the increase of water demands for rice cultivation. Regarding to the water resources management, the groundwater exploitation was well-managed. Besides, there were no conflicts between famers in using surface water for rice cultivation. However, due to certain limitations in interaction between the local residents and the government (district and communes), the local regulations were not sufficiently applied.
