Chilekwa Mumba Courtesy Goldman Environmental PrizeOn Monday, Mumba, 38, was awarded the 2023 Goldman Environmental Prize for Africa for his work for the community and setting legal precedent. The prize is awarded each year by The Goldman Environmental Foundation, with ceremonies in San Francisco and Washington, DC. CNN has contacted Vedanta and the Zambian state mining company for comments. The government, however, says that approved projects will follow environmental policies set by the Zambia Environmental Management Agency (ZEMA). For Mumba, who now runs an orphanage in the Zambian capital Lusaka with his wife, the battle is far from over.
