Border regions face challenges managing natural resources, which include forests, wildlife, air, and rivers. This study aims to provide an overview of research on various natural resource conflicts and cooperation in borderlands worldwide, considering the five spheres of the Earth system, namely the atmosphere, lithosphere, hydrosphere, biosphere, and anthroposphere. The type, scope, and place of natural resource conflicts in the borderlands were examined and key findings for clarifying the conflicts, cooperation, and geographical characteristics were derived using a systematic review methodology. The results indicate that over the last two decades, the conflicts over the hydrosphere are the most dominant. In the following order, conflicts over the biosphere have been frequently dealt with in transboundary areas. In Africa, dams (the anthroposphere) related to the hydrosphere especially influence and cause conflicts as well as cooperation for benefit-sharing among riparian countries. In North America, governance along the transboundary areas has been developed. “In Asia, several neighboring countries are linked through various types of associations ranging from multilateral organizations to sub-national administrations in order to effectively manage the long and wide-ranging natural resources that exist beyond the borders of the countries”. In Europe, numerous protected areas related to the biosphere have been designated. Therefore, this research helps better understand transboundary conflicts based on natural resources and could contribute to designing natural resource management strategies or models in borderlands.
