ACKNOWLEDGEMENT

With the consent of the Vietnam National University of Forestry, Faculty of Forest

resources and Environmental Management, the study caried out the study of“Using

Landsat 8 data and GIS to estimate above-ground biomass and carbon stocks of coastal

mangroves in XuanThuy National Park, Nam Dinh province”.

On the occasion of completing this scientific research, I would like to express deep

gratitude to Dr. Hai- Hoa Nguyen who has guided and helped me in the process of the

implementation and the completion of this study.

I sincerely thank teachers in Faculty of Forest Resources and Environmental

Management for the encouragements and suggestions and for helping me to improve the

quality of my study.

I would also like to express our gratitude to the staff and local people in XuanThuy

National Park communes for the enthusiastic help during my works.

Due to the limited knowledge and experiences, this report is not finalized yet. I‟m

looking forward to receiving feedback from teachers and friends to improve this scientific

research.

ABSTRACT

The Vietnam mangroves have been larger and rich and they play an important role

for forest ecosystems, biodiversity and local livelihoods and development. However, the

management of mangroves in Vietnam is still facing many challenges. The process of

transition to market economy under reform policy has brought high economic growth from

7 to 8% in the first 5 years of the twenty-first century with the changes in livelihood

patterns. Vietnam faces big challenges of environmental problems as a result of

overfishing, mismanagement of natural resources and the pressures of globalization. The

changes in the social, ecological, economic and institutional schemes gave the livelihood

systems of mangroves increasingly complex and vulnerable. To contribute develop

sustainable management of coastal mangroves, the study of “Using Landsat 8 data and

GIS to estimate above-ground biomass and carbon stocks of coastal mangroves in

XuanThuy National Park, Nam Dinh province” was conducted. The study is based on

using NDVI values to identify the distribution of mangroves, apply formula of scientific

research to calculate total of above- ground biomass and then calculate the carbon stocks of

mangroves in XuanThuy National Park. Thereby we can make recommendations for the

conservation and management of mangrove forests more efficiently.
