In accordance with their mandate and the recommendations of their statutory bodies, FAO and UNEP agreed to undertake a reassessment of the present situation and current evolution of the forest resources of the tropical world, within the framework of the Global Environment Monitoring System (GEMS). The FAO/UNEP Tropical Forest Resources Assessment project, signed on 8 November 1978 by both organizations, started on 1 December 1978 and was completed in June 1981.
This report of the assessment in Asia is in two parts. The first briefly describes the methods used and provides the results for the region, the second presents 16 detailed “country briefs”. Two other reports cover tropical America (in Spanish) and tropical Africa (in English and French) respectively and the project conclusions are summarized in a fourth report, published in each of the above languages.
The present total area of the closed forests in the 16 countries studied representing tropical Asia has been found equal to some 305 million ha. Annual deforestation sensu stricto, i.e. clearing for agriculture and other land uses, has been estimated at 1.8 million ha (or an annual deforestation rate of 0.60%) and seems to level off at this amount, mostly because there are few unprotected forests left in the areas of high population pressure. To this figure must be added about 0.2 million ha of deforestation of open woodlands which are relatively less extensive than in the other two main tropical regions. In addition to these processes of forest clearing, various forms of degradation are taking their toll on the different types of woody vegetation, especially through over-exploitation for fuelwood. Intensive management applies to one fifth only of the productive closed forests, being concentrated to the extent of 85% in one single country. Plantations are gaining momentum, especially for fuelwood production and other non-industrial purposes. Although the ratio of area planted to area deforested every year is still less than a quarter, it is worth noting that 40% of the plantations at the end of 1980 were established in the five preceding years.
The work has been conceived and carried out by the project coordinator, Mr. J.P. Lanly, assisted for tropical Asia by the following experts (in alphabetical order): Messrs. S. Andel (2 countries), P. Coppin (2 countries), J. Guellec (interpretation of satellite imagery), Y.S. Rao (regional synthesis), R.M. Saxena (5 countries), K.D. Singh (2 countries) and A. van der Zon (3 countries). The analysis of the forest resources situation of India and Burma and the drafting of corresponding country briefs were carried out under an agreement with FAO by the Indian Preinvestment Survey of Forest Resources (Messrs, C.L. Bhatia, J.P. Aggarwal and R.M. Saxena) and the Burmese Forest Department (Mr. Shwe Kyaw) respectively. The many experts and institutions consulted which kindly collaborated are gratefully acknowledged and their list given on the next page.
The study is both timely and appropriate as it presents factual, quantitative data needed to support policy decisions covering the conservation, development and wise utilization of the present resources of tropical Asia. We contemplate the revision of these initial data over the coming years in order to keep governments and the international community correctly informed as to the state of tropical forest resources and their evolution at any given time.
