WATER SAFETY IN THE GREATER MEKONG REGION

 

Climate Change impacts to water safety in the Greater Mekong region

Srepok is a tranboundary river basin and it is the major tributaries in the Greater Mekong River basin. The region is extremely vulnerable to adverse effects of changing climate that result in flooding and droughts. Furthermore, considering the poor living condition of local communities and the difficulties in reaching common agreements in water management among national and international stakeholders, assessing climate change impacts on the region through a droughts and flooding model is necessary in order to a better management of the river’s water.

CASE STUDY DESCRIPTION

Issue to be addressed

Vietnam and Cambodia’s development goals in the Srepok river basin are several and the costs by disaster events are high for both countries. Nevertheless, the lack of consistent and coherent data, does not allow policy makers to set adaptation plan to climate change. Therefore, we aim to provide climate and hydrological data and information through the flooding and droughts model that can be projected into the future, helping decision-makers in sustainable development and disaster resilience.

Decision support to client

The analysis is expected to reveal information on how the frequency of floods/droughts have happened and will increase/decrease in the future. The clients are local functional departments, especially Mekong River Commission (MRC) and Vietnamese Disaster Management Center (DMC), who are decision-makers. They could base their decisions on these results to apply appropriate measures and prepare adaptation, and mitigation plans in the near future. If the results could provide an approximation of the future reality, MRC and DMC would be able to avoid huge economic losses and minimize impacts on local people.

Temporal and spatial scale

The Srepok River basin in Vietnam and Cambodia and its sub-basins (86) will be explored. To facilitate both near future and far future assessments, we will provide the indicators for different time ranges; normally, absolute values are given for a reference period (e.g. 1971-2000) and the expected future changes for different 30-year periods, such as early century (2011-2040), mid-century (2041-2070) and end-century (2071-2100).

Knowledge brokering

NAWAPI, as a governmental agency, has close operational relation with all local functional departments, especially with MRC and Vietnamese Disaster Management Center (DMC). NAWAPI and MRC have a long history of collaboration in the management of the Greater Mekong River basin, where NAWAPI operates in the national boundaries, while MRC takes care the entire basin from an international prospective. Therefore, the information flow is smooth and constant.

NAWAPI often collaborates with DMC providing forecasting information. Furthermore, MONRE (Ministry of Natural Resources and Environment) delegates both NAWAPI and the DMC in order to handle several national issues, supporting their cooperation.
