However, production of salient climate information in Africa is hindered by limited availability of and access to weather and climate data, especially in central and north Africa . Existing weather infrastructure remains suboptimal for development of reliable early warning systems . For example, it is estimated only 10% of the world's ground-based observation networks are in Africa, and that 54% of Africa's surface weather stations cannot capture data accurately . Some programmes are trying to address this issue, including the trans-African hydro-meteorological observatory , the West African Science Service Centre on Climate Change and Adaptive Land Management  , the Southern African Science Service Centre for Climate Change, Adaptive Land Management   and the AMMA-CATCH National Observation Service and Critical Zone Exploration Network . However, the sustainability of observation networks beyond the life of these programmes is uncertain as many African National Meteorological and Hydrology Services experience structural, financial and technical barriers to maintaining these systems .
