Teak (Tectona grandis) with its outstanding physical and aesthetic qualities is recognized as one of the most important and valuable hardwoods in the world. It has been used for many centuries for a range of products in furniture manufacturing and housing construction as well as its cultural services. Natural teak forests covering an area of about 29 million hectares occur in central and southern India, Lao PDR, Myanmar and Thailand. However, natural teak forest area has reduced substantially in all native teak growing countries mainly due to over exploitation, agriculture expansion, and shifting cultivation. In particular, old-growth high-quality teak stands have declined significantly for many years and there is a high risk of losing their high diversity of genetic traits and wood characteristics. The Activity is aimed at assisting governments, local communities and smallholders to enhance natural teak forest management, production and marketing to facilitate the establishment of legal and sustainable wood supply chains while improving national economy and local communities’ livelihood in the Greater Mekong Sub-region. The Activity provides an opportunity for the recipient countries to build-up sustainable forest management capacities and to further pursue their strategic objectives and policies on the sustainable development of teak forest resources, which are of particular livelihood improvement and ecological significance in all countries of the Greater Mekong Sub-region.
