| Research Abstract |
According to the latest FAO statistics, we are loosing 15.4 million ha of tropical forests world-wide. Among these tropical deforestation, only 3.9 million ha, or one fourth is counted for by Asia and Pacific. Yet in terms of deforestation ratio to forest cover area, Asia and Pacific suffer more than the other regions. Especially, Continental South Eastern Asia poses 1.8%, and Insular South Eastern Asia, 1.4% whereas the world average is 0.8%.
Comparing these situations, forest cover is now increasing in most developed countries, though they have had lost enormous amount of forest once. By the same token, we expect the same turn in developing countries. But WHEN and HOW?
We choose the Philippines, Thailand, and Indonesia to study in depth. These countries belong to different stages of socio-economic development. According to United Nation's classification, Indonesia is classified as "low-income economies" with $570 per capita GNP in 1990 with its annual growth rate of 4.5% for the period of 1965-1990. The Philippines and Thailand belong to "middle-income economies" classification with $730 and $1,420 per capita income and 1.3% and 4.4% annual growth rates respectively.
The Philippines almost used up its natural forests and now trying to restore it through social forestry approaches. The level of economic activities doesn't seem to affect deforestation there. In case of Thailand, economic growth brought about higher timber prices, which promotes tree farming with assistance of the government. Indonesia has relatively abundant amount of forest left. With this natural forest traditional shifting cultivation is being replaced by non-traditional and environmental disturbing type of slush and burn agriculture.
We studied remote sensing techniques to estimate area of clearing forest and other disturbance in forest in Indonesia and area of new plantation in Thailand to evaluate the above said situations in each country.
