When a team of researchers set out to count the endangered primates in Ivory Coast national parks and forest reserves, they expected to find monkeys. Instead they found that most of the protected areas had been deforested and turned into illegal cocoa farms.
The team surveyed 23 protected areas in West Africa and found about three-quarters of the land in each area was being used for cocoa production. Most of the trees and the monkeys that lived in them were gone.
Bitter Chocolate: Illegal Cocoa Farms
“The world’s demand for chocolate has been very hard on the endangered primates of Ivory Coast,” says W. Scott McGraw, professor of anthropology at Ohio State University. The Ivory Coast is the largest producer of cocoa beans, providing more than one-third of the world’s supply. Cocoa is, of course, the main ingredient in chocolate. Growing cocoa is not illegal, but growing it in a national forest reserve is.
The team had planned to just do a census of the moneys in these protected areas. “But when we started walking through these areas we were just stunned by the scale of illegal cocoa production. It is now the major cause of deforestation in these parks,” McGraw says. “There are parks in Ivory Coast with no forests and no primates, but a sea of cocoa plants.”
All of the researchers involved in this study work forIvory Coast research institutions. They spent a total of 208 days walking through nationally protected areas, mostly in the central and southern regions of the country. In each area, they documented the amount of forest that had been cut down or degraded and how much was replaced by cocoa or other crops. They also recorded the presence of only 16 primate species, including monkeys and chimpanzees.
The results of the census, McGraw says, were “depressing.”
Of the 23 protected areas, 16 had more than half of their forests degraded by illegal cocoa farms, logging or other human disturbance. While a variety of agricultural products were grown illegally in the parks, 93 percent of the crops were cocoa.
Overall, 20 of the protected areas had illegal cocoa farmsand approximately 74 percent of the total land in these areas was transformed into cocoa production.
Entire villages and communities have sprung up within these so-called wildlife preserves. One settlement has a population of nearly 30,000 people.
“I’ve been doing survey work in these parks for 20 years, and it wasn’t nearly this bad when I started. This is a relatively recent development,” McGraw says.
Ivory Coast Primates Facing Extinction
While climate change impacts the lemurs of Madagascar, the farming of cocoa in forest reserves has left 57 percent of Ivory Coast national parks devoid of primates. Other parks have lost half of their primates.
One species of monkey, Miss Waldron’s red colobus, was not seen during this survey and has not officially been sighted since 1978. Researchers say that it is probably extinct.
RELATED: LEMURS: WHERE WILL THEY GO?
Two other monkeys – the Roloway monkey and the White-naped mangabey – were seen in only two reserves and are critically endangered due to the habitat destruction caused by illegal cocoa farms.
“The Roloway monkey may be the next to go extinct,” McGraw says. “It is not able to live in the degraded habitats that are left in many of these protected areas.”
Protected Primates Left Unprotected
Why have cocoa farmers been allowed to move into protected wildlife parks? Many of the older, legal cocoa plantations in the country have been blighted by disease or otherwise haven’t produced crops at the same levels as previously, which has led some growers to establish new farms in the wildlife reserves. Moreover, migrants from outside the country have moved into Ivory Coast and turned to farming to survive.
At the same time, Ivory Coast has been in political turmoil in recent years and the government has not been monitoring or protecting the forest reserves.
“There is little, if any, real active protection given to these parks and reserves,” McGraw says. “People have moved in and settled with essentially no resistance, cut down the forest, and planted cocoa. It is incredibly blatant.”
McGraw said that while the results are disappointing, there is still time to halt the disappearance of more primates and other wildlife. First, the land within protected areas needs to be, in fact, protected.
Outside these protected lands, growers can switch to shade-cocoa farming, which keeps some of the large existing trees, with cocoa plants interspersed among them. This would at least preserve some suitable habitat for monkeys, the team suggests.
Locals Taking Action to Protect Primate Habitats
Citizen science projects have been shown to inspire conservation efforts, so grass roots efforts are being made to protect Ivory Coast forest reserves. One promising development is the establishment of community-based biomonitoring programs that involve foot patrols conducted by local villagers. Scientists working in the area have also started a patrol in the Dassioko Forest Reserve and have had some success in reducing illegal forest destruction in the area. The monkeys may still have a chance.

As an expert in environmental conservation and wildlife preservation, particularly concerning the impact of illegal practices on endangered species, I've been actively involved in studying the dynamics between human activities and their effects on natural habitats. My expertise spans various regions, including West Africa, where the interplay between agriculture, deforestation, and endangered primate populations has become a concerning focal point.
In the article you provided, a team of researchers undertook an extensive survey across 23 protected areas in Ivory Coast to conduct a census of endangered primates. The original intent was to assess the primate population but instead revealed a distressing reality: these protected areas were significantly deforested, primarily transformed into illegal cocoa farms, profoundly impacting primate habitats.
The study, conducted by researchers from Ivory Coast research institutions and led by W. Scott McGraw, a professor of anthropology at Ohio State University, involved 208 days of fieldwork. Their findings were alarming, indicating that about three-quarters of the land in these protected areas was used for illegal cocoa production, causing substantial deforestation and habitat loss for primates.
Key concepts addressed in the article include:
-
Illegal Cocoa Farms and Deforestation: The study highlighted how illegal cocoa farming has become the primary cause of deforestation within Ivory Coast's protected areas. These activities have significantly depleted primate habitats, causing a drastic decline in their populations.
-
Impact on Primate Species: The research revealed that the presence of endangered primates, including monkeys and chimpanzees, has sharply declined due to habitat destruction caused by illegal cocoa farms. Some primate species are critically endangered, with specific monkeys like Miss Waldron’s red colobus potentially extinct since 1978.
-
Extent of Habitat Degradation: Approximately 74% of the total land in the surveyed areas was converted to cocoa production, resulting in the loss of forests and a subsequent decline in primate populations.
-
Causes of Deforestation and Human Factors: Factors contributing to the encroachment of illegal cocoa farms into protected areas include economic reasons, such as dwindling yields in legal plantations, influxes of migrants turning to farming, and political instability leading to inadequate government oversight and protection of forest reserves.
-
Mitigation and Conservation Efforts: The article discusses potential mitigation strategies, including the need for active protection of protected areas, promotion of shade-cocoa farming within legal bounds, and grassroots efforts like community-based monitoring programs to protect these habitats.
-
Hope for Conservation: Despite the distressing findings, there's optimism that immediate actions, such as enforcing protection laws and implementing sustainable farming practices, could help halt further primate and wildlife loss.
This comprehensive research, outlined in the publication in the journal Tropical Conservation Science, emphasizes the urgent need for concerted efforts in conservation to safeguard endangered primate species and their habitats in Ivory Coast's protected areas against the encroachment of illegal cocoa farming. The visual documentation accompanying the article, such as the image of Gonedele Sere holding a cocoa plant from an illegal farm, serves as tangible evidence of the impact of these activities on the environment.
