Deforestation is a severe environmental problem in North Korea. Beginning in 2001, the government implemented ten-year reforestation projects with few positive outcomes. Inter-Korean forestry cooperation began in 1999. Local governments and NGOs were the main implementers of cooperative projects from South Korea. The two Koreas had also been seeking financial and technical support from international organizations. This study examines the cooperative networks between government agencies, NGOs, and international organizations and financing possibilities to identify the reasons why so little has been accomplished. It also provides a meaningful contribution to the understanding of comparative relationships among the stakeholders and practical recommendations to improve the effectiveness of cooperative forestry programs in North Korea.
