Abstract:
Many previous studies both nationwide and worldwide have indicated
negative impacts of hydropower dams on land and water use, especially in
Lower Mekong River Basin (LMRB). This article aims to analyze the
sustainability in living conditions, concerning the issues in
social-economic, and environmental aspects among LMRB countries. Data of
natural and man-made conditions of the upstream sub-region or regions
are collected for a specified period and a correlation model on some
typical variables and parameters is studied. The conflicts both visible
and invisible categories between Mekong River Commission countries,
i.e., Water Scarcity, Drought, Salinity intrusion, and negative impacts
on Social, Economic, Environmental aspects and policy are firstly
analyzed. Secondly, a matrix of correlation between the factors explains
partially the relationship between causes and effects in a complicated
system. By prescribing eight variables concerning main factors upstream,
and using their average values, data of the four countries such as Lao,
Thai, Cambodia, and Vietnam are tabulated. From this table, the matrix
of correlation between the factors is found. Then based upon the
equation of water balance, together with increasing or decreasing trends
of the correlation between variables, the water scarcity downstream is
explained. Finally, this paper discusses some measures for mitigating
water scarcity in the region.
