Beschreibung
Presently there is a global increase in the recognition of environmental, social and economic values of native vegetation, particularly in terms of both sustainability of agricultural production and maintenance of natural resources. Land-use/land-cover (LULC) change is one of the main triggering factors for local resource conflicts in third-world countries like Sudan. However, balancing human needs and ecosystem functions requires quantitative knowledge about ecosystem responses to land-use. Being able to gain a better understanding of such profound changes is a priority concern of the research community. Fundamental elements of such research should, however, beside the basic human forces that motivate or drive theses changes incorporate their impact on biophysical processes. Remote sensing provides cost-effective multi-spectral and multi-temporal data usable for the mapping and modelling of LULC processes. The ability to model and predict patterns of some biotic variables on the basis of physical landscape attributes could mitigate the damage and facilitate the preservation of biodiversity. It is necessary to develop spatial modelling methodologies for rapid and cost-effective mapping of degraded areas to assess their biological value for nature conservation and their natural restoration potential.
