Tens of thousands of illegal human settlements pose a real threat to the continued existence of an endangered elephant population, according to satellite analysis of the Babile Elephant Sanctuary in eastern Ethiopia by University of Oxford researchers and the Born Free Foundation.

Researchers from Oxford's School of Geography and the Environment and Born Free found, in the 11 years to 2017, the number of illegal houses in the sanctuary soared from 18,000 to more than 50,000. Of these, some 32,000 houses are in the area in which elephants range.

According to the researchers, unless the integrity of the sanctuary can be restored, and security and poverty issues resolved, the elephants of the Babile Elephant Sanctuary will be lost within a short time. The sanctuary is home to Africa's north-easternmost population of African Savannah Elephants - one of only six populations recognised in Ethiopia.

The country's human population now stands at more than 110 million and there is a chronic shortage of land and a high demand for natural resources.

Previous studies have found that, in Ethiopia, the integrity and effectiveness of many protected areas are being compromised by increasing human-related pressures, inadequate government support, and civil conflict.

Emily Neil, a postgraduate researcher with Oxford's School of Geography and the Environment, says, 'The situation in the Babile Elephant Sanctuary is critical. There are now only around 250 elephants left. Without the rapid resolution of the many human issues putting pressure on the elephants it is difficult to foresee a future in which this population of elephants survives.'

Human pressure on the elephant population comes from different directions. Between 2015 and 2019, the Born Free Foundation ran a field project in the sanctuary, mobilising Ethiopian Wildlife Conservation Authority rangers to conduct daily monitoring of the elephant population. This helped researchers to understand better the elephant's range and established that, in addition to poaching, human-elephant conflict is a significant cause of elephant mortality.

Within a context of a burgeoning rural human population dependent on scarce natural resources, chronic civil instability, poverty and food insecurity, the team believes that the environmental, poverty, and security challenges in the sanctuary need to be addressed jointly.

The article will be published in Oryx -The International Journal of Conservation - after the embargo lifts.

Nearly 30 percent of UK birds endangered, report warns
London (AFP) Dec 1, 2021
Almost 30 percent of the UK's bird species including greenfinches and swifts are facing serious threat to survival due to factors including climate change, a report published Wednesday warned. The "red" list of 70 birds considered most endangered was put together by a coalition of organisations the Royal Society for the Protection of Birds (RSPB) based on the observations of volunteers. The last such report was published in 2015. RSPB chief executive Beccy Speight said the report "is more ev ... read more
