Space for Hunting: Understanding Indigenous and other Hunters’ Impacts in the Congo Basin Forests

  1. 1. Space for Hunting Understanding Indigenous and other Hunters’ Impacts in the Congo Basin Forests John E. Fa, Jesus Olivero, Andrew Noss, Hirokazu Yasuoka, Michael Riddell, Jerome Lewis, Serge Bahuchet, Miguel Angel Farfán, Jesus Duarte, Romain Duda, Sandrine Gallois, Guiseppe Carpanetto, Shiho Hattori, and Robert Nasi
  2. 2. • Pygmy communities identify themselves as ‘forest peoples’ due to the fundamental importance of the forest to their culture, livelihood and history. • Each is a distinct people, such as the Twa, Aka, Baka and Mbuti living in countries across central Africa, including the Central African Republic (CAR), the Democratic Republic of Congo (DRC), Rwanda, Uganda and Cameroon. • Different groups have different languages and hunting traditions. • Although each community faces different threats and challenges, racism, logging and conservation are major problems for many, all contributing to serious health problems and violent abuse.
