The jungles of Colombia’s Pacific coast are home to more species of amphibians and birds than anywhere else on Earth – and to 3.5 million Afro-Colombians, poor people caught in the crossfire of industrial development and agriculture, civil war, mining and logging. Every year, up to 80,000 hectares of rainforest are destroyed. So social worker Libia Grueso co-founded the Process of Black Communities (PCN), to advocate for both the rights of Afro-Colombians and environmental protection. In volatile Colombia, taking this kind of leadership is dangerous; others who have supported sustainable development have been assassinated. But Grueso and others helped the Afro-Colombian community gain territorial rights over nearly 2.5 million hectares. The PCN has since successfully challenged oil palm plantations, logging and industrial shrimp farming, which harms local mangroves. It is encouraging traditional farming and helping communities to be self-sufficient.
