Botswana Considers Culling Elephants

People living on the outskirts of Botswana’s game parks are anxiously waiting to see if the government is going to do anything to stop roaming wildlife from killing villagers and eating and destroying their crops.

The government is in the process of debating whether to cull elephants, revoke the 2014 ban on hunting or try to keep the wildlife off villagers’ land.

Communities living on the outskirts of fence-less, state-owned parks and forest reserves say their lives are proof that wild animals cannot coexist harmoniously with human beings.

Botswana President Mokgweetsi Masisi appears to be sympathetic to the plight of these communities who are attacked and killed by wild animals and whose crops are eaten and destroyed.

Culling and hunting options have sparked widespread opposition and criticism from animal rights groups and conservationists.

In what appears to be a political crusade to justify culling and hunting as options, the Botswana government has said:

– 25 people have been killed by elephants between 2009 and this year so far;

– Botswana has an elephant population of 130 000 against its carrying capacity of 54 000;

– More than 70% of the elephant population lived outside their designated areas.

Melting Glaciers bring threat of Flash Floods

The Himalaya, the breathtaking consequence of the battle between two tectonic plates, is home to spectacular mountains and a family of glaciers whose waters sustain 1.65 billion people across the region. The thawing of these glaciers leaves behind a myriad of lakes, some of which can suddenly burst their banks and flood downstream.

A satellite-based assessment of 1,291 glacial lakes in the Tibetan Plateau and along the main Himalaya range found that 16 percent of them potentially threaten human settlements. Since 1935, around 40 glacial lake outburst flood disasters have taken place across the Tibetan Plateau.

Environment

Cool Roofs

A new study finds that making rooftops a light-reflective colour can reduce heat-related deaths and cool peak daytime temperatures by more than 3 degrees Celsius during heat waves.

Cities store more heat than the surrounding countryside due to the urban heat island effect. This makes cities more susceptible to the increasing number and intensity of heat waves under global warming.

New modelling by the University of Oxford found that introducing cool roofs across a city could prevent about a quarter of heat wave-related deaths and cut the need for air conditioning.
