Water balance for ma river basin in context of climate change

WATER BALANCE FOR MA RIVER BASIN IN THE CONTEXT OF CLIMATE CHANGE MSc Thesis ABSTRACT Water is one of the most common and most important substances on the earth's surface It is essential for the existence of life, and the kinds and amounts of vegetation occurring on various parts of the earth's surface depend more on the quantity of water available than on any other single environmental factor (Kramer, Paul J.; Boyer, 1995) Facing with water crisis has singled out as a major worldwide concern Under the main impact of Climate change, it is considered as an added driver for many of the societal and environmental problems of the 21st century Climate change may affect water systems through increased/unusual spatio-temporal variability, long-term temperature and water balance changes, and sea-level rise which in turn have implications for water security, food security, energy security, health of human and ecosystems, and human livelihoods (Vörösmarty et al 2000; Richardson et al 2011) Water availability will be increasingly affected by climate change, which in Africa could expose 250 million people to greatered water stress In some countries drought could halve the yields from rain-fed agriculture by 2030s Across Sub- Saharan Africa and South and East Asia drought and rainfall variations could lead to large productivity losses in cultivated food staples (Development, 2015) By the contrast of the decrease of water availability and the increase of water demand gather with the conflict between different interests of stakeholders become a huge water management task The Ma River basin is one of the largest rivers in central Viet Nam, orginated from the southern of Dien Bien province, flowing through the Ma river district of Son La province, through Laos and into Vietnam by Ba Thuoc district, Thanh Hoa province Ma river basin has abundant water resources However, the demand for water is rising day by day under the pressure of population and development - social growth Moreover, the uneven distribution of water resources in time and space with the requirements of environmental flows, leading to water shortages appear Besides, the competing interest of different stakeholders even exaggerates the issue Moreover, Le Thi Huong Thom Page i WATER BALANCE FOR MA RIVER BASIN IN THE CONTEXT OF CLIMATE CHANGE MSc Thesis impact of climate change on temperature and annual rainfall also has to concern as its negative influence to water supply capacity The objectives of research are to analyze the water balance in the basin in three scernarios: baseline (2002-2012), future scenarios with socio-economic development text into account impacts of climate change (RCP4.5 and RCP8.5) in 2030s The water use activities in this basin such as irrigation, industry, domestic… are also taken into account In order to get these objectives, WEAP model is implemented to simulate the water balance in the basin MIKE-NAM model is used to simulate the inflow to ungauged basins CROPWAT model is applied to estimate the water requirement for crop The results shows that the imbalances between water supply and water demand occur in the dry season In 2030s, the system cannot supply sufficient water quantity for the projected growing demand of socio-economic development scenario The unmet demand is going up compared to the current scenario However, the situation is much more severe in the scenario in which the climate change impacts are considered Le Thi Huong Thom Page ii WATER BALANCE FOR MA RIVER BASIN IN THE CONTEXT OF CLIMATE CHANGE MSc
