The co-founder and CEO of charity Tusk has told CNBC that the shutdown of the tourism industry in Africa due to the Covid-19 pandemic has caused an economic crisis which is impacting conservation in the region.Charles Mayhew, who is based in the U.K., co-founded the charity in 1990, with a mission to “amplify the impact of progressive conservation initiatives across Africa.” It was started in response to the poaching crisis throughout the 1980s which saw up to 100,000 elephants killed annually, and Prince William, the Duke of Cambridge, became the charity’s Royal Patron in 2005.Tourism and safaris play a crucial role in financially supporting local workers, communities and wildlife conservation projects, and often pay for rangers to protect both species and land in Africa. However, the sector has been hit hard as a result of the coronavirus pandemic, which seen international travel come to a halt.Mayhew, who among other roles was formerly an insurance broker in the City of London, told CNBC the impact of the coronavirus had been “absolutely enormous.””The reality on the ground in Africa is such that the economic impact and crisis that has flowed from the pandemic has been really significant, mainly because tourism and the travel industry has absolutely shut down, it fell off a cliff, when we all went into lockdown,” he said.Madikwe game reserve, Safari, African elephant, South Africa.

Mayhew said that the involvement of the Duke of Cambridge had been a game changer for the charity.”He’s raised the profile of the charity which has made a huge difference in our ability to raise funds and to be recognized in the donor community as a credible organization. So that’s been immensely valuable” he said. “When he meets the conservationists … and the communities that we’re working with, it really increases their morale and their belief in what they’re doing hugely because he just brings this fantastic spotlight onto the work that they’re doing.” Since they were established in 2013, the Tusk Conservation Awards have set out to “celebrate African-based conservation leaders and wildlife rangers” and their work with communities and wildlife on the ground. This year’s event saw three winners receive awards and a financial grant from the charity. The Prince William Award for Conservation in Africa recognized the lifetime achievement of Hipólito Lima, in Sao Tome and Principe, for dedicating his life to sea turtle conservation, in a region which traditionally hunted them for their meat and eggs. The Tusk Wildlife Ranger Award 2020 was awarded to Zimbabwe Parks and Wildlife Management Authority Principal Intelligence Officer, Amos Gwema, for changing the way intelligence work helps to protect wildlife in Zimbabwe. And John Kamanga, executive director of the South Rift Association of Land Owners, received the Tusk Award for Conservation in Africa for his work in helping local communities and wildlife to co-exist in the South Rift region of Kenya.Mayhew said that as well as a continued focus on ending the illegal wildlife trade, the biggest challenges in African conservation were human-wildlife conflict and loss of habitat, given that the continent’s population is expected to rise from 1.2 billion to 2.4 billion by 2050.
