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: Atoms don't like jumping rope

Nanooptical traps are a promising building block for quantum technologies. Austrian and German scientists have now removed an important obstacle to their practical use. They were able to show that a special form of mechanical vibration heats trapped particles in a very short time and knocks them out of the trap.

By controlling individual atoms, quantum properties can be investigated and made usable for technological applications. For about ten years, physicists have...

Im Focus: Images from NJIT's big bear solar observatory peel away layers of a stellar mystery

An international team of scientists, including three researchers from New Jersey Institute of Technology (NJIT), has shed new light on one of the central mysteries of solar physics: how energy from the Sun is transferred to the star's upper atmosphere, heating it to 1 million degrees Fahrenheit and higher in some regions, temperatures that are vastly hotter than the Sun's surface.

With new images from NJIT's Big Bear Solar Observatory (BBSO), the researchers have revealed in groundbreaking, granular detail what appears to be a likely...

Im Focus: New Pitt research finds carbon nanotubes show a love/hate relationship with water

Carbon nanotubes (CNTs) are valuable for a wide variety of applications. Made of graphene sheets rolled into tubes 10,000 times smaller than a human hair, CNTs have an exceptional strength-to-mass ratio and excellent thermal and electrical properties. These features make them ideal for a range of applications, including supercapacitors, interconnects, adhesives, particle trapping and structural color.

New research reveals even more potential for CNTs: as a coating, they can both repel and hold water in place, a useful property for applications like printing,...

Im Focus: Magnets for the second dimension

If you've ever tried to put several really strong, small cube magnets right next to each other on a magnetic board, you'll know that you just can't do it. What happens is that the magnets always arrange themselves in a column sticking out vertically from the magnetic board. Moreover, it's almost impossible to join several rows of these magnets together to form a flat surface. That's because magnets are dipolar. Equal poles repel each other, with the north pole of one magnet always attaching itself to the south pole of another and vice versa. This explains why they form a column with all the magnets aligned the same way.

Now, scientists at ETH Zurich have managed to create magnetic building blocks in the shape of cubes that - for the first time ever - can be joined together to...
