This paper gives an overview of the awareness and global policies on deforestation and reforestation, with attention to biodiversity and sustainable forest management. As forests have important functions for the human environment, forest disturbance directly impacts the human and environmental conditions. Awareness of these conditions result in many initiatives and programmes dealing with combating deforestation and enhancing reforestation. These programmes have been highlighted by international organizations and institutions a longtime before the Earth Summit in Rio de Janeiro 1992. Implementation of these global programmes need multilateral cooperation between international institutions on the one hand and between national governments, NGO's, local people, and forestry sector on the other hand. Preparations of the implementation of those programmes have been started both at international and national levels.
