7Conclusion 71
The first aim of the WKIEMP baseline reports are to synthesize a quantitative description of the baseline project situation along the ecological and socioeconomic dimensions that are relevant for project implementation. In this context, flexible strategies for selecting priority intervention areas and households at the landscape/population scale are proposed. The second aim is to lay a foundation for change detection that considers spatial variability explicitly.
