  2. 2. There have been 815 hydropower projects approved with a total installed capacity of 24,324.3MW. In these 815 approved projects, there are 268 hydropower plants in operation with capacity of 14,240.5MW and over 205 projects under construction with capacity of 6,198.8MW. 5th International Disaster and Risk Conference IDRC 2014 ‘Integrative Risk Management - The role of science, technology & practice‘ • 24-28 August 2014 • Davos • Switzerland www.grforum.org (Source: The International Journal on Hydropower & Dam – 2011)

  10. 10. 5th International Disaster and Risk Conference IDRC 2014 ‘Integrative Risk Management - The role of science, technology & practice‘ • 24-28 August 2014 • Davos • Switzerland www.grforum.org Operation/Management  The potential for hydropower projects to address flood control task in central Vietnam is limited due to its topography.  In most reservoir operation procedures, the regulation is that 2 hours prior notice be given before discharge occurs. The rainfall observation network is very sparse in the Central region and rain gauges are measured only every 12 hours (at 7pm and 7am).  Residents have limited to access to information relating to reservoir operating and flood discharge procedures. In addition, local authorities lack specific provisions to empower communities to seek compensation.
  11. 11. 5th International Disaster and Risk Conference IDRC 2014 ‘Integrative Risk Management - The role of science, technology & practice‘ • 24-28 August 2014 • Davos • Switzerland www.grforum.org Initial Observations 1. Forest management should be given immediate attention. The Strategic Environment Assessment in all river basins should be studied for sustainable development in water resources. 2. It is important to build the capacity of the rainfall observation network in order to enhance forecast accuracy and increase the notice before flood discharge. 3. All reservoir dams at level three must have monitoring equipment installed that provides the observation data of water levels and discharges in reservoirs and this data must be accessed on a system. 4. It is necessary to establish a dam safety committee and build reservoirs and dam data/information management in Vietnam.
  12. 12. Added value for the Post 2015 Framework for 5th International Disaster and Risk Conference IDRC 2014 ‘Integrative Risk Management - The role of science, technology & practice‘ • 24-28 August 2014 • Davos • Switzerland www.grforum.org Disaster Risk Reduction • How did your work support the implementation of the Hyogo Framework for Action: – Identify, assess and monitor disaster risks: data and statistical loss in Vietnam. – Provides a more solid footing for decision makers. – Creating a holistic framework to solve problems caused by human intervention in the ecosystem. • From your perspective what are the main gaps, needs and further steps to be addressed in the Post 2015 Framework for Disaster Risk Reduction in – Research: More locally driven research in developing countries – Education & Training: Capacity building of local institutions, enhanced disaster management courses and programs – Implementation & Practice: Investment in prevention and preparedness, recognition of value in this investment – Policy: Working WITH decision-makers on research, enabling change
