| Zusammenfassung |
| This paper aims to assess the vulnerability at regional level, the model and
the proposed indicators being explicitly intended for an essentially rural
region, in this case–Tutova Hills (Eastern Romania). Five categories of
variables were taken into account to define the vulnerability components:
rural habitat, demographic features, agriculture, environmental quality and
emergency situations. For each one, five variables were analyzed and ranked
based on the level of determination or subordination. In order to ensure the
flexibility of the model and to avoid the criteria duplication in assessing
vulnerability, only a single indicator of each category was retained and
included in analysis: total number of inhabitants, dependency ratio, weight
of arable land on slope categories, weight of land under forestry and road
accessibility of villages. The selected indicators were mathematically
processed in order to maximize their relevance and to unitary express the
results in the spread 0–1. Also, values of each indicator were grouped
into four classes, corresponding to the level of vulnerability: low, medium,
high and very high. A general index was obtained through the integration of
vulnerability factors in an equation based on the geometric mean. Spatial
analysis was based on features of the MicroImages TNTmips 7.3. software,
which allow the vulnerability mapping. This approach argues and states that
vulnerability assessment through indicator-based methods can be made only
according to the level and scale of analysis and related to natural or human
conditions of a region. |
