ter extract low intensity agriculture. In addition to the develop-
ment and adaptation of existing algorithms a specific request is
the successful integration of these into a strong logistical
framework within the FMoA, in order to bring together the ad-
vanced knowledge to elaborate and apply mapping processes
and the regional knowledge on contexts of the production types.
On basis of the ESA and third party mission sensor portfolio,
the established institutional collaboration network, which
GMFS established during the past years, is bringing together
both aspects.
Extracted from the ENVISAT MERIS Full Resolution (FR)
level 2 products (GSD = 300m), the Fraction of Absorbed Pho-
tosynthetically Active Radiation (fAPAR) is derived. Data of
the fAPAR type are biophysical variables directly correlated
with the primary productivity of the vegetation, and they reflect
the fraction of the solar energy which is absorbed by the vege-
tation within each pixel.

Within the framework of the GMFS project, we have elaborated
and transferred a processing chain for the generation and analy-
sis of these indicative fAPAR inter seasonal maps (see fig. 4) to
the FMoA in Khartoum.
Figure 5 shows the distribution of potential rain fed areas
between the crop seasons 2009 (light yellow) versus 2010
(hatched light brown) in North Kordofan State, Sudan
(Brockmann 2011). The thematic overlays show a decrease
from North to South of the potentially cultivated area in the
Eastern part of the state, while at the same time an increase is
observed from the South towards the North in the Western part
of the state. Compared to the official statistics of the FMoA,
which estimate an increase of 1096 of production in North
Kordofan for the same period, the satellite data obviously
indicate that there is much more spatial differentiation needed.
Based on those annual EO application results, the FMoA is now

improving its monitoring framework for the benefit of the rural
population in the fragile environment of traditional rain fed
agriculture.

The results in the application sites confirm the approaches by
means of annual monitoring of the variation in the extend of the
rain fed agriculture and special indicators like in season fAPAR
maps, which are transmitted to the local units of the respective
Ministries of Agriculture. Together with specific training
modules and joint user conferences, the basis of spatial
knowledge is a pertinent improvement of the day-to-day
working basis for the African project partners.
2.4 Application Sites in the Western Siberian Corn Belt
2.4.1 Transfer Approach: The positive responses and
convincing results have been the basis for the transfer of the
methods into another region, the Western Siberian corn-belt. In
a joint programme funded by the German Ministry for
Education and Research and the Russian Ministry of Research,
the project called “Sustainable Land Management and Adaption
Strategies to Climatic Change for the Western Siberian Corn-
Belt” (SASCHA) was started one year ago. The large extends
of cropping schemes in West Siberia demand advanced remote
sensing methods to be applied in order to compare the impacts
of climatic change not only on the agricultural production but
also on risks for the eco system. The experiences from the
African activities will also introduce a multi scale approach of
remote sensing data. From a nearly daily product of medium
resolution (typically MERIS with 300m GSD) for wide areas,
and high resolution sensors for stratified sample areas once per
season to very high resolution data for stratified spot
observation, the project will develop and establish an adopted
monitoring concept.
The project SASCHA investigates interactional effects of cli-
mate and land-use change on natural resources and ecosystem
functions in the Pre-Taiga and Forest-Steppe ecotone of West-
ern Siberia. The interface between the steppe and the northern
forest zone in Western Siberia is of global significance in terms
of carbon sequestration, food production, and biodiversity. Af-
fecting all these subject matters, climate change and rapid
socio-economic development will trigger fundamental land use
changes. The analysis of these former, present and future
changes and their implications for essential ecosystem functions
are the focus of the first project phase. Subsequently, sustain-
