The humansphere is part of the biosphere but is addressed separately due to its significance.
The humansphere in the Gina River catchment show following characteristics:
- The Gina River catchment is inhabited by Dorze people.
- Their basis for living is subsistence economy. Crop-growing, cattle-breeding and collecting fuel wood are the main income generating activities (Beck et al. 2004). Thus, the local population depends heavily on good quality natural resources.
- Due to population growth (about 3 %, like in other rural areas in Ethiopia) the demand for natural resources is increasing. This applies especially to the soil resources, as the investigation of the drainage basin showed (see land use).
