• Talking about tree cover
• Data for an ongoing story
• Generating story ideas
• Working with the team at Global Forest Watch (GFW)

9. Tree cover loss is not always deforestation
Tree cover loss is defined as the complete removal of tree cover for any reason. It
includes both human-caused loss and natural disturbances, and loss that is
permanent or temporary.
Deforestation typically refers to human-caused, permanent removal of
natural forest cover.
Global Forest Watch has data on tree cover loss. Tree cover is a convenient metric
for monitoring forest change because it is easily measurable from space and
satellite imagery. It is difficult to monitor deforestation with satellite imagery
alone.
More info at research.wri.org/gfr/key-terms-definitions
Talking about tree cover:

10. Why the focus on tropical primary forests?
Primary forest are mature rainforest that are especially important for biodiversity,
carbon storage and regulating regional and local climate effects.
More than 96% of deforestation, or human-caused, permanent removal of
forest cover occurs, in the tropics.

22. Developing Data Stories:
Using Global Forest Watch for
Journalism
By Madeleine Ngeunga, Rainforest Investigations Fellow

23. A long story with Global Forest Watch tools
● Investigating forest management and
policy, agribusiness and land grabbing,
Indigenous rights, land-use conflict,
climate change, and environmental
justice issues in the Congo Basin
region and beyond.
● Using data-driven stories to highlight
the political, social, and environmental
factors causing forest loss across the
Congo basin region and beyond.
● Global Forest Watch fellow in 2019
● Pulitzer Center Rainforest
Investigations Network fellow in 2021-
2023.
● Part of the Pulitzer center team
supporting African journalists across
sub-saharan Africa to report on
rainforestrelated issues and conduct
investigative journalism.
● Also works as an editor with InfoCongo

24. Deforestation alertsbeyond the limitsof logging titlesand agricultural
plantation in Lokoudje/South Cameroon.
A series of 7 collaborative investigations produced &
co-publishedby Le Monde and InfoCongo, in
partnershipwith the Pulitzer Center’s Rainforest
Investigations Network
The system behind the looting
of Cameroon’s forest
A troubling increase in illegal logging
cases, with legal logging companies
found to be the culprits.

25. Cameroon Forest Atlas
GFW and Forest Atlas for national overview of the logging activities

26. Many companies use the logging
title just to launder timber from
other areas.
From the Forest Atlas
and data hidden into
public documents
Building a new database
Over the years, several of these
companies have been sanctioned for
illegal logging, including cutting
timber beyond the limits of the area
assigned to them.

27. An Opaque Agro-
industry Razes
Cameroon’s
Forests with
Impunity
Investigating Forest Loss: RADD alerts + Forest Atlas + PLANET imageries

28. Interpreting the data
InfoCongo in partnership with the Rainforest Investigation
Network/Pulitzer Center analyzed satellite images of the area
allocated to the agri-business company, from PLANET over
three major time periods.
A=Undisturbed Forest: In image A, December 2019, no
disturbance is visible on this plot of forest yet.
B=Cleared forest: As of December 2020, there is a significant
tree cover loss. This occurred 3 months after Camvert planted
its first oil palm plants, after the forest had been destroyed.
C=Oil palm plantation: A year later, we noticed the emergence
of well-marked oil palm plantation plots.

29. In South Cameroon, how a new palm
plantation led to vast clearing of forest,
triggering human and wildlife conflicts.
● The company started its activities on
the pathway of large mammals of the
Campo man national park
● We mapped fresh traces of elephant
dung and footprints a few steps from
the Bagyeli camp
● We combined and analysed the field
trip data with Forest Atlas/Global
Forest Watch and Planet imageries
● The endangered mammals of the
park are confused following the
destruction of the forest in which
they used to roam.
Interpreting the data

30. Impact
Following our series of stories on the The system behind the looting of Cameroon’s forest
the Cameroonian Ministry of Forestry and Wildlife reacted.
He sent an administrative letter to its regional representatives and the director of forest control
points ordering them to reinforce forest control, because he heard there was a lot of illegal timber
being transported across the country.
This is typically what we explained in our series + exposing case of illegal logging involving
companies owning logging titles.
It's one of the first times in Cameroon that the government has reacted to the publication of
an article and not denied the facts. On the contrary, for our series, the Ministry of Forests is
urging its representatives in the field to step up controls on timber transport, in order
to combat the transport of illegal timber.

Chasing Deforestation
Using near-real-time satellite alerts to track deforestation and inspire
journalism that reveals the stories within the data.

Mongabay is a
global
non-profit
newsroom
dedicated to
reporting on
the world’s
most important
ecosystems

35. There are
over
11,000
active
satellites
in orbit

37. We’re using near-
real time data and
an algorithm that
identifies areas
with concerning
levels of tree
cover loss.
37

38. Using this data, journalists are responding
to alerts by investigating the causes of
recent deforestation
38

39. 39
Why do we need to use an algorithm?
Alerts provide a wealth of information,
but there are literally millions of alerts
each month – we need a way to filter.
Methodology
1. Divide world into grid cells
(10 km x 10 km)
2. Calculate an “importance score” for
each grid cell
1. Count alerts by grid cells
2. (a) Incorporate protected areas
2. (b) Plus intact forest landscapes

40. 40
Methodology (continued)
3. Multiply the score by the
number of alerts that month
4. Select the top 10 grid cells
per region (exclude
anything with too low of an
importance score)
3. The importance score is multiplied by the number of alerts
4. Locations outside the top 10
grid cells is filtered out

41. 41
Methodology (continued)
5. Curation of locations to select the most interesting stories

42. “Bolivia: Indigenous territories cornered by the
agricultural expansion of a Mennonite
community”

43. 43
Satellite data

assignments
People see

They feel

44. 44
Reporters mobilized
to examine and

through
documentation,
interview, and
analysis.

45. 45
One story is small.
Data puts it in
context.
Mongabay used
GFW data to
discover similar
patterns in
multiple locations.
