e The institutional setting,
e Differences in the perception of problems, e.g. between
producers and users of (geo-graphical) information.
The value of detailed land use descriptions to e.g. soil scientists
is in the simultaneous capturing of dynamic soil characteristics
so that detailed analyses of impacts by land use on the resource
base can be made.
Monitoring of soil, land cover, weather and land use dynamics
at different scales of time and space is on many agendas. Note-
worthy are initiatives undertaken by ICASA (International Con-
sortium of Agricultural Systems Applications), LUCC (Land
Use and Land Cover Change; IGBP), and CLAUDE
(Coordinating land use and land cover data and analysis in
Europe; EC-DGXII).
The land use concepts discussed in this article are fully devel-
oped and ready for operational use. Comprehensive studies,
especially when it concerns time series and when primary data
are collected by field-staff, will benefit greatly from them. A
few aspects work against their adoption:
e they require insight in the stochastic nature of land use
aspects and of the underlying data model,
o analyzing and classifying generated data remains complex,
e — at present no organization has a history of systematically
collecting, storing, and utilizing land use data at the level
of detail presented,
e they are not yet part of an operational GIS system or a
comprehensive land use systems database,
e using the concepts is often not felt as a pre-requisite for
land use studies.
It is to be expected that Information Technology will increas-
ingly facilitate the development of integrated, quantitative tools
for fand use systems analysis based on simulation of dynamic
land-use interactive processes. Already there is a strong ten-
dency towards increased use of geo-informatics in the design of
interdisciplinary geo-information systems and decision-support
systems for realizing sustainable land management at different
scales and for specific user groups (e.g. Chu Thai Hoanh 1996;
Ceccarelli 1997). A digital geo-information infrastructure and
policy framework is emerging for this purpose at global, re-
gional, national and local levels (e.g. Eurostat 1999). This will
make important research data available that are at present inac-
cessibly stored in archives and libraries.
Lambin ef al. (1998) state that data compilation for land use
and land cover research would benefit from harmonization and
streamlining of data collection and interpretation procedures.
Issues that require special attention are dataset development,
integration of heterogeneous data sources, improved accessibil-
ity of data, data accuracy and error propagation, and identifica-
tion of robust and meaningful indicators. Continued efforts to
improve the quality, completeness, spatial and temporal consis-
tency and compatibility of heterogeneous land use and land
cover related data are thus required.
