When a mining firm in Obuasi found malaria was hampering its operations, it joined forces with locals and the government to find a solution. Now others want to emulate their success
Nestled in the Ashanti region of southern Ghana, the small town of Obuasi is encircled by hills, largely forested but bearing scars from open-cast and illegal mining. Eighty kilometres south of the country’s second city, Kumasi, it is a community of subsistence farmers and miners.
One of the world’s largest gold mines, it has been quarried since the 1890s. But right now the underground drills are silent and a quieter operation is underway, digging out one of the world’s smallest but most deadly predators: the malaria mosquito.
