Forest monitoring and management


June 2009 ~ June 2011

Forest is one of the very important natural resource of Lao PDR. The forest starts to dwindle due to various reasons including forest fires, logging and for use as domestic energy source. It is said that an estimated 300,000ha of forest lands are lost every year. WREA is mandated to study the forest/water management system in Lao and it is essential to identify areas that are under pressure threatening loss of forest resources that could lead to water related problems including floods and drought. Therefore, it is very much important to establish clear methods and technology for monitoring forest resources of the country. The objective of this prototype is the followings;

1. To generate the land cover map of 2008 at national level.

2. To generate 100 meter or better resolution forest cover map in a demonstration river basin for water resources management.

3. To build capacities of WREA and MAF technical staff in using Space Technology for environment monitoring.
