Solidarity in a competing world can be seen from different perspectives. Looking from an intergenerational viewpoint, declining biodiversity may hamper potential options of future generations. Under intensive agricultural activities biodiversity is often declining rapidly, heating up the “sharing or sparing” discussion. Our study shows the impact of large-scale rubber plantations on biodiversity, represented by different plant and animal species.
We used genuine data derived from up to eight years of multidisciplinary field research. Primary data on the distribution of vascular plants, pollinator species, ground beetles, ungulates and other selected mammals were collected in two study sites in Southwest China and Southern Thailand. The two sites shared similarities in land use and included intensively cultivated rubber plantations bordering protected areas. We supplemented these data with literature studies on the impact of rubber cultivation on the diversity of amphibians, reptiles and birds (all along mainland South East Asia). Based on this combination, we developed a classification scheme that enables the integration of different facets of biodiversity: 1) diversity of red list species representing a conservation approach (red list), 2) diversity as such representing intrinsic values of biodiversity (aggregated biodiversity), and 3) diversity of species with human use value (medicinal plants and bees) representing an anthropocentric approach (human use).
