About Oxpeckers

The Oxpeckers Center for Investigative Environmental Journalism is Africa’s first journalistic investigation unit focusing on environmental issues. The Center combines traditional investigative reporting with data analysis and geo-mapping tools to expose eco-offences and track organised criminal syndicates in southern Africa.

Oxpeckers is a non-profit company that aims to dramatically improve the quality and impact of African environmental journalism, by:

  • Providing a home for investigative journalists interested in environmental issues;
  • Hosting geo-narrative platforms that use cutting-edge mapping techniques and forensic data tools to improve reportage;
  • Stimulating transnational and transcultural investigative reportage through project or research-based Oxpecker Fellowships;
  • Sharing investigative resources / source documents / data, as well as specialist tools and skills through Oxpeckers manuals and workshops;
  • Curating specialist environmental reporting and research projects on behalf of media partners;
  • Publishing our own exclusive environmental investigations, in both legacy and new media, as well as through eBooks and other channels.

What we do

Oxpeckers uses best-of-breed mapping visualizations and geo-data analysis to track and expose the criminal syndicates, corrupt officials and greedy corporations that are looting Africa’s natural resources across international borders.

Complex stories are told visually using dynamic infographics, “single story” animated maps and data visualization to augment more traditional story packages.

Oxpeckers is developing the most comprehensive database of eco-offences in Africa. The resulting reportage is published online and through media partners, with the underlying evidence and other source materials available to other media and environmental guardians for use in their own work.

Oxpeckers has a network of Associates based in Southern Africa and elsewhere who specialise in environmental reporting. Our work features, inter alia, in Mail & Guardian, Huffington Post SA, Times Live, Sunday Times, Daily Maverick.

Embedded Oxpeckers Fellows, on secondment from other media in Asia and Africa, spend three-month fellowships with the unit using our resources and tools to investigate major environmental stories for their home audiences and home media. Fellows usually go on to join our Associates network.
