Water basins serveas a basis for

regional cooperation and development.

• On track to meet the MDG drinking water target: only 26 of the 53 countries

• Water related diseases: more than 80% deaths for children under 5

• Deficient agricultural water management: e.g. only 10% of irrigable lands are actually irrigated in WA.

• Hydropower development < 7% of the potential

• 5-25% of GDP due to droughts and floods in affected countries

• Climate impacts are greatest in poor countries.

The 1st GEOSS African Water Cycle SymposiumJan. 2009

GEOSS African Water Cycle Symposium

Tunis, 6-8, Jun., 2009

109 participants from 16 countries 4 UN Agencies 2 Space Agencies

12 from Africa 2 from Europe 1 form North America 1 from Asia

African Water Cycle Coordination Initiative: contributing to GEOSS

Participants considered convergence and harmonization of observational activities, techniques, interoperability arrangements, and effective and comprehensive data management as the most fundamental elements that can be addressed under the GEOSS framework, including activities, programs and guidelines under UN agencies and non-UN agencies (AfDB, ESA, JAXA, NASA etc .).
