Water authorities in Africa receive training in Earth Observation

07.12.2007
Some 30 water authorities from more than 15 African countries gathered in Nairobi, Kenya, from 26 to 30 November, to attend an advanced ESA TIGER training course on utilising Earth Observation technology to overcome water-related problems.

"The course was very useful, especially for those in the field, as tools are very limited in Africa," Patrick Khisa of Kenya said.

Khisa said the course, hosted by the Regional Centre for Mapping of Resources for Development, helped him to identify how and where to get data for wide-scale applications. For instance, until recently he has been monitoring the water levels of Lake Victoria using ground data. During the course, he learned he could monitor lake levels using data from the space-based instrument radar altimeter.

The course provided an overview of the different applications of Earth Observation (EO) technology for improving integrated water resource management, with special attention placed on the needs of Africa. European and African experts discussed various topics, such as catchments characterisation, hydrological modelling, water quality and drought forecasting.

For Charles Tanania Kabobo, who is in charge of the Congo River Basin Information System, the course allowed him to learn the latest remote sensing techniques and its application to water management. Kabobo plans to introduce EO techniques in the field of water management in the Democratic Republic of Congo, where EO data is not currently used.

The training course was organised in collaboration with ITC (International Institute for Geo-Information Science and Earth Observation), the African Water Facility (AWF) of the African Development Bank and the World Hydrological Cycle Observing System (WHYCOS) – a programme of the United Nations’ World Meteorological Organization (WMO).

ESA launched the TIGER Initiative in 2002 following the World Summit on Sustainable Development in Johannesburg. The initiative’s primary objective is to help African countries overcome problems faced in the collection, analysis and dissemination of water related geo-information by exploiting EO technology.

Water resources are scarce across Africa where the hydrological network is the world’s least developed. Water resources are also unevenly distributed across the continent, with western and central Africa enjoying much higher rainfall than Northern Africa, the Horn of Africa and southern Africa. The Democratic Republic of Congo has a quarter of all African freshwater on its territory, while arid Mauritania has just 0.001%.

During the last few years ESA and its partners (Committee on Earth Observation Satellites (CEOS), United Nations Educational, Scientific and Cultural Organization (UNESCO), the UN-Water/Africa group, the African Development Bank and more than 100 African representatives from water authorities, universities and technical centres) have been working together under the auspices of African Ministerial Conference on Water (AMCOW) developing the capacity in Africa to improve integrated water resource management by exploiting the advantages of EO technology.

For instance, ESA is currently working with water authorities in Egypt and the Lake Victoria Basin to design, develop and implement EO-based capacities for the operational monitoring of water quality in Lake Manzalah and Lake Victoria. Because lakes are a precious source of freshwater, the usage of lake water must be carefully managed to satisfy a variety of different, and often competing, domestic, agricultural and industrial uses.

These projects will both provide a set of comprehensive water quality products derived from EO data on turbidity, chlorophyll-a concentration, suspended sediment concentration, aquatic vegetation cover and reclaimed areas.

Im Focus: A “cosmic snake” reveals the structure of remote galaxies

The formation of stars in distant galaxies is still largely unexplored. For the first time, astron-omers at the University of Geneva have now been able to closely observe a star system six billion light-years away. In doing so, they are confirming earlier simulations made by the University of Zurich. One special effect is made possible by the multiple reflections of images that run through the cosmos like a snake.

Today, astronomers have a pretty accurate idea of how stars were formed in the recent cosmic past. But do these laws also apply to older galaxies? For around a...

Im Focus: Visual intelligence is not the same as IQ

Just because someone is smart and well-motivated doesn't mean he or she can learn the visual skills needed to excel at tasks like matching fingerprints, interpreting medical X-rays, keeping track of aircraft on radar displays or forensic face matching.

That is the implication of a new study which shows for the first time that there is a broad range of differences in people's visual ability and that these...

Im Focus: Novel Nano-CT device creates high-resolution 3D-X-rays of tiny velvet worm legs

Computer Tomography (CT) is a standard procedure in hospitals, but so far, the technology has not been suitable for imaging extremely small objects. In PNAS, a team from the Technical University of Munich (TUM) describes a Nano-CT device that creates three-dimensional x-ray images at resolutions up to 100 nanometers. The first test application: Together with colleagues from the University of Kassel and Helmholtz-Zentrum Geesthacht the researchers analyzed the locomotory system of a velvet worm.

During a CT analysis, the object under investigation is x-rayed and a detector measures the respective amount of radiation absorbed from various angles....

Im Focus: Researchers Develop Data Bus for Quantum Computer

The quantum world is fragile; error correction codes are needed to protect the information stored in a quantum object from the deteriorating effects of noise. Quantum physicists in Innsbruck have developed a protocol to pass quantum information between differently encoded building blocks of a future quantum computer, such as processors and memories. Scientists may use this protocol in the future to build a data bus for quantum computers. The researchers have published their work in the journal Nature Communications.

Future quantum computers will be able to solve problems where conventional computers fail today. We are still far away from any large-scale implementation,...
