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.

Oxpeckers is a non-profit company that aims to dramatically improve the quality and impact of environmental journalism, in Africa and other parts of the globe, 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;
  • 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.


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 was founded and is headed by Fiona Macleod, a seasoned investigative environmental journalist who is pioneering the use of new media tools to expose eco-offences and to track offenders around the world.

Macleod won the prestigious SAB EnviroMedia Written Media Award in 2018 for collaborative multimedia journalism projects, and the Print and Online Award in October 2014 for the Oxpeckers Fellowship project. Under her leadership, Oxpeckers was 2019 Merit Award winner in the Asian Environmental Journalism Awards, 2017 SAB Environmental Journalist of the Year, CNN Multichoice African Environment Journalist of the Year in 2016, and 2016 Journalist of the Year at the China Environmental Press Awards.
