The EC-FAO Partnership
Programme on Information and Analysis for
Sustainable Forest Management: Linking National and International Efforts in
South Asia and Southeast Asia is designed to enhance country capacities to
collect and analyze relevant data, to disseminate up-to-date information on
forestry and to make this information more readily available for strategic
decision-making. Thirteen countries in South and Southeast Asia (Bangladesh,
Bhutan, Cambodia, India, Indonesia, Lao P.D.R., Malaysia, Nepal, Pakistan, the Philippines,
Sri Lanka, Thailand and Viet Nam) participate in the Programme. Operating under
the guidance of the Asia-Pacific Forestry Commission (APFC) Working Group on
Statistics and Information, the initiative is implemented by the Food and
Agriculture Organization of the United Nations (FAO) in close partnership with
experts from participating countries. It draws on experience gained from
similar EC-FAO efforts in Africa, and the Caribbean and Latin America and is
funded by the European Commission.
