Greening a Tropical Abijata-Shala Lakes National Park, Ethiopia - A Review

Tadesse Fetahi

The aim of this review is to assess and document the status of Abijata-Shala Lakes’ National Park (ASLNP), to investigate the possible causes for the water level reduction of Lake Abijata and to promote sustainable utilization of the Park. The Park was established to protect and conserve large number of water birds that use Lake Abijata as feeding and Lake Shala as nesting and breeding grounds. Actually, Lake Shala is the continent’s most important breeding colony of great white pelicans. The Park also provides wintering ground and maintenance station for large number of birds including from Southern African, Sub-Saharan and Palaearctic species. Consequently, the Park was submitted to the Ramsar Convention on wetlands as an international important candidate site. However, this natural heritage is currently deteriorating due to human encroachment, grazing by cattle, uncontrolled water abstraction and other anthropogenic activities. Since the 1980s, the water level of Lake Abijata has significantly dropped, fishery has totally collapsed, and birds such as Lesser Flamingo (Phoeniconaias minor Geoffroy) and Great White Pelican (Pelecanus onocrotalus roseus) have been migrating to nearby lakes. Briefly, the lake is shrinking (so far greater than about 100 km2) and facing imminent threat of collapse obliterating the existence of the Park. As a result, the Park is one of IBAs (Important Bird and Biodiversity Areas) in danger sites, which are priority sites for immediate action. To improve this deteriorating condition of the Park, I demonstrate resources use of the Park within the framework of green economy, which protects ecosystem services and utilizes natural resources sustainably. Lastly, a few recommendations for management measures are outlined as mechanisms to protect the ecosystems and the park.
