African Wildlife Parks Face Climate, Infrastructure¹ Threats

Africa's national parks are home to thousands of wildlife species such as lions, elephants and buffaloes². The protected areas are increasingly threatened by below-average rainfall and new public systems projects.

Climate change is already worsening an extended period of severe dryness in eastern Africa. Increasing development, including oil drilling and agriculture, are hurting conservation efforts in protected areas, several environmental experts say.

The at-risk parks are in Kenya, Tanzania, Mozambique, South Africa, Congo and other countries.

The parks not only protect plants and animals. They also act as natural carbon sinks. This means they store carbon dioxide and help reduce the effects of global warming.

An estimated 38 percent of Africa's biodiversity areas are under severe threat from climate change and infrastructure development, said Ken³ Mwathe. He is with the organization BirdLife International.

Investors⁴ see the areas as ready for development, Mwathe said, adding the governments have some responsibility for that. Governments have opened "the land in these areas for infrastructural⁵ development" he said.

African nations are seeking to raise living standards and meet sustainable development goals, including access to clean water and food, economic growth and improved public education. The effort leads some governments to start large building projects. Many of them are through foreign investments, especially from China.

The proposed East African Oil Pipeline⁶ is an example. Uganda's government says the project can help lift millions out of poverty. However, the plan calls for the pipe to run through Uganda's Kidepo Valley, Murchison Falls and Bwindi Impenetrable Forest. Such plans threaten species and have drawn⁷ criticism from climate campaigners.

Population growth and the construction that comes with it have also added to the pressure on parks, conservationists said. But they add that replacing wildlife with infrastructure is the wrong way for economic growth.

"We have to have a future where wildlife is not separated from people," said Sam Shaba. He is the program manager at the Honeyguide Foundation, an environmental non-profit organization in Tanzania.

When "people start to see that living with wildlife provides the answer to sustainable development ... that's the game-changer," Shaba said.

Most of Africa's wildlife parks were created in the late 19th and early 20th centuries by colonial rulers. They fenced the areas and ordered local people to stay out.

But now conservationists are seeking more inclusive policies for operating the parks. They seek the expertise⁸ of Native communities that live around the parks and can help protect them, said Ademola Ajagbe. He is the Africa regional managing director of The Nature Conservancy.

The peoples of these areas are forced to move "such as the Maasai (in Tanzania and Kenya), Twa and Mbutis (in central Africa) who for generations have lived with wildlife," said Simon Counsell. He is an advisor⁹ with Survival International.

"Africa is depicted¹⁰ as a place of wildlife without people living there and this needs to change," he said.

The effects of worsening weather conditions in national parks due to climate change should also not be ignored, experts said.

A recent study carried out in South Africa's Kruger National Park linked extreme weather events to the loss of plants and animals.

Drought has seriously threatened species like rhinos¹¹, elephants and lions as it reduces the amount of food available, said Philip Wandera. He is a former officer with the Kenya Wildlife Service now teaching conservation at the Catholic University of East Africa.

More intensive management of parks and removing fences that prevent species from traveling to wetter areas are important first steps to protecting wildlife, Wandera said.

He added that financial help to "support communities in and around parks" would also help protect them.
