Why different Spatial Scales?
- Vulnerability is geographically and socially differentiated
- Spatial heterogeneity results in more accurate description of reality
- Differences in vulnerability components
- Differences in vulnerability factors
- Political and administrative division can facilitate or impede the availability of data, according to certain scales. Data from river basins stretching out over more then one country will be more difficult to estimate; data from urban areas may vary from country data
- The results can be more applicable and understandable through accumulation of knowledge of how vulnerability is distributed and how it is developing throughout the world
