Host countries will benefit by gaining access to technology that will build the infrastructure required to meet their development needs while also benefiting the global climate. Accordingly, a large big German company decided in spring 1998 to invest DM 30 Mio in a forestry CO2 mitigation project. This demonstrates well that after Kyoto there are much better chances to receive funds for agroforestry and fuelwood projects by the mechanism of JI. It has been demonstrated by scientific calculations (see Table 2; Swisher, 1991) and practical experiences from many pilot projects since 1989, there is a great potential for greenhouse gas mitigation by agroforestry. The increasing use of biomass and its conversion efficiency for producing heat, electricity, and liquid fuels can become a significant factor in the global management of atmospheric CO2 over the next century (Sampson et al., 1993). Consequently these opportunities should be used intensively in the interest of a sustainable development, especially in tropical countries.
