A British non-governmental organization is working with the government of Angola to clear mines from one of Africa’s largest and most diverse wildlife areas. Among the goals in making the region safer for all life in it is to allow tens of thousands of elephants trapped in neighboring Botswana to return to their native Angolan habitat.

Drone Flying to Detect Civil War-Era Mines in Natural Reserve

The Halo Trust has been one of the leading global organizations working to clear minefields left in the wake of wars in recent decades around the world. In addition to its campaign clearing some 153 mined areas created during Angola’s 1975-2002 civil war, it is now also focusing on efforts to rid the Kavango-Zambezi Trans Frontier Conservation Area (KAZA) of hidden explosives. 

That five-country zone is home to the famous Okavango Delta that boasts some of the world’s most diverse and thriving wildlife. But the abundance of mines in the Angolan sector has made it impossible for migrating elephants in Botswana to make their way back home.

To rectify that, Halo has called in the drones.

The NGO is using a fleet of uncrewed aerial vehicles equipped with laser and light detection and ranging tech to locate and defuse mines across a 12-mile corridor through southern Angola. 

Though only a small part of its wider struggle to clear the entire country and region of mines, the specific objective in that drone-driven project is to allow elephants trapped in Botswana to migrate back to their original Angolan habitat. Their abundance in Botswana has not only started posing serious problems for local residents, but also led the government to lift a ban on hunting the giants in 2019 as a way of reducing their numbers.

The solution to avoid that massacre, Halo believes, is to use its drones to locate and clear mines in the migratory corridor in southern Angola.

 After that, thousands of elephants that were stranded across the border after fleeing civil war violence can return home. Prior to the war, Angola had a population of over 100,000 elephants; some estimates put that number at less than 3,500 today. Botswana, by contrast, hosts over 130,000 ­elephants – the largest in Africa – with tens of thousands of those originally from Angola. KAZA as a whole is home to 50% of the world’s elephants.

Elephant Bottleneck Angers Local Farmers

Farmers in Botswana complain over-population of the creatures has resulted in shortages of their natural food sources. That, they say, regularly pushes them into farmed areas to eat, trample, and otherwise destroy crops. There are also claims of wild elephants occasionally wrecking villages and attacking people, which has further fueled human anger.

With Botswana’s elephant numbers continually growing – and those in Angola still dropping despite the return of peace – Halo has made a major objective of reopening the migration corridor. That, it is hoped, will reduce pressure to the south, and protect elephants from resumed hunting by permitting them move safely back where they came from.

“Since 1994 we have destroyed almost 100,000 landmines in Angola. Initially we focused on removing landmines in regional capitals and towns… Today, our work is focused in rural areas, clearing landmines that have plagued communities for over 30 years,” Halo says of its work in the area – including the new drone innovation. 

“By clearing the landmines, Halo can lay the foundation for life, agriculture and eco-tourism to return and thrive, bringing many benefits to over half a million people in Cuando-Cubango Province alone.”
