Project's information

Project's title Research in the impacts of climate change on sea turtle populations in Vietnam
Research hosting institution Institute of Marine Environment and Resources
Project leader’s name Chu The Cuong, MSc
Project duration 01/01/2012 - 01/01/2014
Project’s budget 300 million VND
Classify Excellent
Goal and objectives of the project

• To study the biological, ecological characteristics of breeding sea turtle populations in Vietnam
• To assess the impact of climate change (including global warming, sea level rise and storm) to the breeding populations of sea turtles in Con Dao National Park (Ba Ria - Vung Tau) and Nui Chua National Park (Ninh Thuan)
• To propose solutions to manage, protect and reserve the sea turtle populations in climate change

Main results

• Scientific results:
- Data set on status of sea turtles in Vietnam
- Data set on the biological and ecological characteristics of sea turtle breeding populations
- Microclimate model and DEM model to assess the impacts of global warming, sea level rise and storms basing on climate change scenarios. The prediction data on impacts of climate change to sea turtle breeding populations in Vietnam
- The solutions to manage and protect sea turtles in climate change
• Applied results:
Findings of the research has provided the scientific basis for the management and protection of sea turtles in their nesting areas, particularly in the areas of Con Dao National Park and Nui Chua National Park. The micro climate and DEM models predictions in temperature and sea level rise will help the management boards can perform better in sea turtle conservation in the future.

Novelty and actuality and scientific meaningfulness of the results

Project was successful assess the current status of sea turtles in Vietnam and the threats to these populations, especially in areas where the number of sea turtles are relatively abundant. The biological and ecological characteristics of sea turtles have been described and evaluated in detail. This is one of the first studies on the reproductive biology of sea turtles in Vietnam
Micro climate and DEM models are applied for the first time in the study of sand temperature fluctuations and sea level rise in Vietnam. It is also one of very few studies in the world applied these models in sea turtle research.

Con Dao National Park, Nui Chua National Park, Cu Lao Cham Marine Protected Area, Phu Quy Marine Protected Area, Phu Quoc Marine Protected Area

Recommendations

Due to the limitation on time and financial support, studies on calculating the pivotal temperature of Green turtle population, assessing the impact of wave surges on nesting beaches etc, can not be conducted. Therefore, we expected that the Vietnam Academy of Science and Technology will continue support us in the future.
