2.1 Environmentally sensitive area identification system to identify desertification
risk at sub-national target area scales. (AUA and UNIBAS-DPV-AF))
A proto-type mainly state indicator
methodology was developed under Framework Programme IV to identify and
map environmentally sensitive areas to desertification at the municipality
scale. A description of it is given in Kosmas, Kirkby and Geeson (Eds).
1999. Key indicators of desertification and mapping environmentally
sensitive areas to desertification. European Commission (Directorate
General, Science, Research and Development). The methodology is based
on measured attributes relating to soil, climate, vegetation and management
quality. It has already been applied in the four target areas (Alentejo
Region-Portugal, Guadalentín Basin-Spain, Agri Basin-Italy, Lesvos
island-Greece) and in the Puglia Region-Italy (European Soil Bureau).
Maps showing types of ESAs ranked by environmental degradation conditions
and management quality from critical (or high-risk) areas to non-affected
areas have been compiled for each of these regions. This methodology has
already been adopted by some of the UNCCD Annex IV National Committees
for mapping ESAs at the national level and has been included in the Greek
National Action Plan to Combat Desertification.
However, the proto-type methodology
is based on 16 separate parameters. If it is to be widely applied, outside
the target areas for which it was developed, and across all the Annex
IV affected countries, it needs to be simplified in order to produce maps
of ESAs, highlighting desertification risk, for a full range of stakeholders,
based on readily available data and at low cost. The range of indicator
types also needs to be expanded to include those relating to desertification
impact through changes in landscape function, driving forces and pressure
indicators and response indicators which will be identified in Part 1.
In order to simplify the methodology,
the sensitivity of the various parameters used to define ESAs will be
analysed to obtain an optimal set of simple and efficient key indicators
related to all the categories of indicators (driving forces, pressures,
state, impacts and responses), the following steps will be followed.
ESAIS, including stakeholder-identified indicators
These state indicators will then be
combined with the candidate indicators identified in Part 1 into an Environmentally
Sensitive Area Identification System (ESAIS). Based on the results of
the sensitivity analysis and the results obtained from the focus group
work packages an ESAIS will be developed based on an optimal, low cost
and efficient group of key indicators for highlighting desertification
risk available to a full range of stakeholders.
data base for each target area
The ESAIS database for each target
area will be compiled by combining the information on the state, response,
pressure and driver indicators derived from the work packages in Parts
1 and 2. The data base will be structured according to the specifications
provided by WP 1.1.
The principal results will be a an environmentally sensitive area identification
system compiled from a number of different indicator types, at the sub-national
target area scale, and the associated data bases for each target area.
