Set of specific GIS products integrating physical and socio-economic
data, used for communicating the Nile issues to a wide range
of stakeholders, and to support decision making;
• Strengthened GIS capacity at national level, in
particular in using GIS for integrating information from
• Strengthened capacity for visual explanation;
• Expanded database, in particular of basin-wide data
information products are perceived as geo-referenced illustrations
of the physical processes driving the Nile regime, and of
the socio-economic parameters framing the Nile development
issues. Their aim is to communicate general information
on the behavior and trends of key variables to decision
makers and the Nile community at large. Cartographic products,
when combined with relevant text and images, have proven
an effective communication tool that is also accessible
to non specialists.
Information Products typically present average and approximate
information derived from regional and global data sources.
The products can be designed to integrate hydrological and
socio-economic information. Their prime role is not to support
the direct decision making process, but to serve as tools
for conception, perception, education, and communication.
data layers of high quality with a basin-wide coverage are
scarce to non-existent in the Nile basin. Remote sensing
is increasingly providing basin-wide satellite images. These
data sets, in particular when combined with field measurements
and local expert knowledge, now provide the prime source
of geo-referenced information for traditionally data poor
regions. The project relies heavily on these international
data layers in the development of cartographic products
that cover the entire Nile basin area. Whenever possible,
regional and global information are combined with data sets
at national and sub-national level.
development of the cartographic products builds directly
on the existing GIS capacity in the Nile countries. The
activity strengthens the national GIS units at the water
departments through training and the provision of GIS software
and computer hardware. Because the map products are produced
at national level, valuable GIS skills are developed while
the national data sets used are subjected to a careful data
quality control exercise.
Water Poster: For a relevant sub-basin in the
national Nile area, counterpart staff has developed a poster
illustrating the relative contribution of the various tributaries
to the main river. The map uses a hill-shaded Digital Elevation
Model (DEM) as background to show the relief of the terrain.
The exercise serves multiple purposes. It is used to quality
control hydro-meteorological data sets and to identify systematic
errors - like missing months or erroneous units. The poster
also trains counterpart staff in using GIS for visual explanation.
The final product is an effective means for explaining the
hydrology of the sub-basin to stakeholders and decision
Vegetation Index Poster: Counterpart staff
in all project countries has prepared posters with 12 images
of average monthly vegetation cover for a relevant national
sub-basin in the Nile area. The illustrations serve to visualize
the spatial and temporal variability of rainfall and associated
vegetation cover over the selected area. As a follow-up,
the 12 monthly images are transferred into an animation
for an average year.
