The role of the hydrological cycle in contributing to the livelihoods of rural communities is often said to be important, but clear evidence of this is rarely offered. Furthermore, where such aspects are considered, they are largely focussed on the use of water from rivers, boreholes or some form of storage (blue water).In this study, the hydrological cycle is considered in its entirety.
Links between rural livelihoods, land use and the goods and services
provided by the evaporation and transpiration components of the
hydrological cycle (green water) are assessed through analyses of rural
livelihoods in the Luvuvhu catchment, Limpopo Province, South Africa.
Results highlight the importance of green water, and thus the importance
of access to land and use of the natural resource base, in disaggregated
rural community livelihood strategies.
Finally, we describe a methodology for linking common outputs from
hydrological models to rural livelihood impacts. In this way, the
potential role of land use change in disaggregated rural livelihoods can
be assessed for various development scenarios, such as increases in
commercial forestry and dryland agriculture.
