ANAW-USA grew out of a friendship between two people, one representing Kenya and the other the United States. For the last two decades, its sister organization, ANAW-Africa, has been a leading voice for animal welfare in East Africa. As a result of ANAW's advocacy, for example, in 2014 ANAW and partners stopped the government from building a road that would bi-sect the Serengeti, a World Heritage site and migration corridor for millions of animals traveling between Kenya and Tanzania. Currently, ANAW is advocating to stop the construction of the Standard Gauge Railway through the Nairobi National Park and working to end the Donkey Skin Trade. Additionally, ANAW is facilitating dialogue on wildlife and environmental crime amongst law enforcers, legal officers, customs, wildlife conservation authorities, and intelligence agencies. ANAW has also established the Africa Conservation Education Fund, which seeks to ensure access to quality, humane education for marginalized communities living in wildlife areas.
