DeSurvey - A Surveillance System for Assessing and
Monitoring of Desertification
DeSurvey integrates 10 modules on an integrated
approach to monitor, assess, and model desertification from local to regional
scales in the European Mediterranean. Integrated remote sensing and geomatics
approaches represent one of the few available options to derive spatially
explicit assessments of areas affected by land degradation or desertification
processes. The geomatics module of DeSurvey primarily envisages to
| (i) |
repeatedly assess land surface conditions based on
standardised indicators for soil and vegetation properties, |
| (ii) |
identify spatial patterns of land use changes and
the underlying forces at regional and local scales, |
| (iii) |
design integrated model-based approaches to assess
and monitor land condition (i.e. the capacity of the land to support
the production of goods and services) in areas prone to land degradation
and desertification processes, |
| (iv) |
evaluate prospective methodological research issues
for future improvements of the overall assessment and monitoring
concepts. |
Geomatics approaches are depending on input
concerning regional hot spot analysis, as supported by a number of other
work packages in DeSurvey, but also provide regional to local scale information.
Hence, it is crucial not to adhere exclusively to the sequence of work
packages, but rather to run an iterative approach leaving room for successive
refinement of results. In that context, the geomatics module will initially
focus on a preliminary set of known “desertification hot spots”
from previous studies (e.g. DeMon-II, GeoRange, Ladamer, Roselt) and available
expert knowledge.
Regarding the portability (to other affected regions) and future applicability
of the DeSurvey mapping approaches it is considered of substantial importance
to evaluate the use of up-to-date sensor systems for improving and replacing
currently used technologies. Specific emphasis will be given to SPOT/VEGETATION,
MODIS/ASTER on the NASA EOS platforms, and MERIS on the European ENVISAT
system, with their synergistic data acquisition and increased detection
capacities. The potential of novel sensors, such as Meteosat Second Generation
(MSG), hyperspectral imagers, and explorative methods will be intensely
studied as an exploratory branch of the DeSurvey geomatics module.
One of the central modules of DeSurvey focuses on geomatics methods and
remote sensing (M 5 – Geomatics based land condition assessment;
PI of M 5: Prof. Dr. Joachim Hill, University of Trier, Germany) –
thematically also the main interest of the Geomatics Department, Humboldt-Universität zu Berlin. The Geomatics Department will concentrate on issues of up- and downscaling
by qualitative and quantitative analysis of geometric high resolution
remote sensing imagery over time spans of 20 to 30 years. This research
is part of DeSurvey work package 5.2 – Local dynamics of land use
systems (PI of WP 5.2: Eric Lambin, University of Louvain, Belgium).
The general objective of WP 5.2 is to characterise the spatio-temporal
processes underlying land use transitions that eventually lead to desertification
at the landscape scale. It will provide local scale estimates of vegetation
cover and LUS changes in the target areas. Spatial models of land use/cover
change and land degradation will be developed and used to identify the
landscape determinants of the location of changes.
