Forest hunter-gatherers and baby chimpanzees

It’s been a year since we first visited five communities in the rainforest in south-east Cameroon.

Two of these are indigenous Baka hunter-gatherer villages, the other three being Bantu farmers. Almost no-one in these villages had used a smartphone before, indeed many of the community members had never even seen one (they don’t come around often in the rainforest). It’s quite amazing that after a handful of meetings, training sessions, and field-trials, all of these communities are not only successfully and independently reporting wildlife crime using smartphones, but taking photos, audio clips, and GPS points!

There is a considerable amount of skepticism from scientists and organisations on the ability of local and indigenous communities to contribute valuable data and act as collaborators, rather than recipients (or obstructions), of conservation programs. For the most part, this is based on a perceived lack of technological capabilities and ecological and holistic knowledge. To say this is a misinformed approach is an understatement; such communities are proving their technological abilities time and time again, their ecological knowledge directly inherited from generations of accumulated environmental interactions. If you’re a quantitative person, the data says it all: 144 reports have been independently taken since June 2017, including 71 photos and 31 audio recordings, directly contributing to anti-poaching efforts.


Re-visiting the communities again on this trip has been as enjoyable as ever. They are clearly both delighted and shocked by our commitment to them, exclaiming “Simon! You’ve come back! How is London?!”, followed by a long series of hugs. Despite several people’s fears that the phones would get stolen or mistreated, every phone and solar panel is in perfect condition – quite remarkable considering they’ve been taken around the rainforest for three months.

Three new communities have began the process of joining the project, after introductory meetings with six. Only those who mention outsiders hunting and trafficking animals in their forest are considered; the project is not to be forced upon any community or initiated where it is irrelevant. One of these new communities is far along a small mud track, quite isolated from town- and city-dwellers, yet they told us of outsiders coming in with lanterns and stealing their resources from the forest. This Baka community has clearly maintained a strong connection to the forest, repeating how the forest is “our father and mother” and telling stories of visiting chimps and gorillas. They expressed their anger and outrage over the designation of a ‘community forest’ for them to utilise; “This does not make sense to us” they said. Cameroon’s 1994 Plan de Zonage, fencing off chunks of land to be allocated to forest and mining concessions, agriculture, protected areas, and community forests, has resulted in forced relocations for Baka hunter-gatherers to the roadsides.

Designing new icons

Technologically-speaking, an interesting event occurred. Whilst re-training a couple of guys in one village as to which icon category to press in order to find specific icons, I asked them “What is this category for?”. They were confused by this and answered incorrectly for almost all of the categories. I found this bizarre as these guys had already sent accurate reports on their own. I rephrased the question, “Where would you go if you wanted to report a poacher’s cabin, for example?”. They immediately pressed the correct icon category and found the icon in question.

Jerome Lewis, my supervisor at UCL, told me of the difficulty for such forest hunter-gatherer groups to recognise the idea of things within things invisible at first (folders, files, categories). Most things in the forest are either there or they’re not. The experience shows that those two guys remember where the icons they want are; the icons for each icon category, though often the same as those for icons inside, are considered almost a meaningless entry point.

With law enforcement currently the bottleneck to action taking place based on community reports, an insight into the mind of a Ministry Chef de Poste was very welcome. This came in the form of a baby chimpanzee. His mother had been shot and he was chained up in a trafficker’s house, up for sale in the illegal pet trade. We received information about the baby chimp from a local businessman who had been made an offer to buy the chimp. After various phone calls, texts, and group talks, we approached the local ministry officer, responsible for illegal wildlife crime. Corruption is the primary issue to effective wildlife law enforcement in Central Africa, and the official had a ‘what’s in it for me?’ attitude. Most interestingly, his primary reservation was fear of reprisal from the community holding the chimp – he would be seen to be at war with local people, despite this being his job. He called a colleague down the road to deal with it. After several days of no updates, we decided to contact the Last Great Ape Organisation (LAGA), a law enforcement NGO in Cameroon with a reputation of getting things done. I wasn’t sure at this point whether the baby chimp had been sold off, or even killed, but finally we received a message: “Thank you for your information. The trafficker has been taken away. The baby chimp is enroute to a sanctuary”. A shame that it took an Israeli NGO to take action, rather than the Ministry’s own wildlife crime officers, but an incredible and rare success story none the less. The baby chimp has been named Farah, and is now in the excellent Mefou Primate Sanctuary, run by Ape Action Africa. You can see a video of his arrival below, and donate to the sanctuary here.


Indigenous Baka hunters vs. The illegal wildlife trade

“Only when the last tree has been cut down, the last river has been poisoned, and the last fish has been caught, will we realise that we cannot eat money” (Plains Sioux Native American)


It’s important to remain optimistic about conservation and inspire people to effect change, but the facts must first be acknowledged: over the past 40 years, 58% of Earth’s vertebrate wildlife has been lost. That means that if you were born in 1970, all of the species that you see around you today only make up 42% of what existed at your birth. There is scientific support to not only declare that we have entered a new manmade geological age, the Anthropocene, but have also initiated the 6th Mass Extinction Event, the 5th being the extinction of the dinosaurs.

Of the key threats identified as responsible for this elimination of animal populations, overexploitation is one to note. In Central Africa, overhunting of forest species – especially forest elephants, western lowland gorillas, chimpanzees, and pangolins – in an incredibly well-planned and efficient commercial international wildlife trade, is emptying the Congo Basin rainforests, the second largest after the Amazon. In Minkébé National Park, northern Gabon, previously regarded as an elephant stronghold, numbers have declined by 80% over 10 years. That’s 25,000 individual elephants and 50-100+ hunted per day.

And that’s just elephants. But probably enough negative stats for now.

Back in Cameroon, I’m again working alongside local colleagues from the Zoological Society of London (ZSL) to develop an app through which forest communities can report and monitor illegal wildlife activity. This is not a top-down effort; we’ve visited each community and held meetings, focus groups, and consultations to find out exactly what issues each is facing, and how they want to use the app, if at all, to tackle these. Indigenous Baka communities should be conservation’s key allies, yet they have been forced out of their forest and treated as part of the problem rather than the solution. Read this post for a quick rundown of the project.

My ZSL colleagues, supervisor from UCL (the brilliant Jerome Lewis) and I have just returned from an area south of the Dja Biosphere Reserve, around the town of Djoum. As the communities themselves decide what they’d like to report and monitor using the app, we went back and forth to the 2 indigenous Baka hunter-gatherer villages and 1 Bantu farming village repeatedly to share ideas, listen to problems they might have with the software, and test out different icons. Interestingly, it was largely not the icons of poachers and animals which villagers found confusing, but rather the cancel icon (red cross), confirm (green tick), and forwards and backwards arrows. This makes perfect sense when you live in a rainforest.


Example of a decision screen


To my surprise, we found both mobile network and data connection in all three villages visited. In the forest! This will make the job a lot easier; records will be able to send without having to climb a moabi tree.

Building up trust with communities is central to having any hope of success. They need to know we’re not just another NGO passing through to make big promises, perhaps building a toilet block someone in New York decided they needed, and never returning. So, we stayed overnight with 2 villages. Both were very hospitable, with one showering us with as much fish, rice, papaya, bananas, pineapple, and cacao pods as we could eat. Sitting around the fire talking with Baka elders about how their grandfathers used to hunt elephants in the forest with spears was a rather unique experience. This Baka village is a strange mix between old forest tradition and the 21st century. One man, who owns a mobile phone and wears similar clothes to mine own, revealed his ancient culture persisting: “I came across a gorilla in the forest. A huge gorilla. And thought it was a grandfather. It was big and I thought it was a grandfather. I saw after a while that it was not a grandfather, it was a gorilla. It started approaching and banging on trees aggressively, and so I started cutting branches, waving and throwing them, and shouted until it moved on”.


It can be tough having to spend weeks in a country you don’t really understand, don’t speak the language, eating what you’re given, being hot and sweaty most of the time, and getting constant attention and comments because of being white. But the positives also stack up: excellent music (like this and also this from Guinée), fried plantains, beautiful forest. Cameroonians are a friendly and happy bunch (Bantu and Baka alike), even in situations with great food insecurity and endless corruption. One boy asked me for money to buy some deep-fried beignet (a rare occasion). After my declining, he merrily replied “d’accord”, and trotted down the street.

But the best positive is the rewarding nature of the work. As part of completing the initial free, prior, and informed consent process, we test the community members who are keen to take part on what the possible advantages of the project will be for them:

“If the records get registered we will be very happy. This will give us control over the forest”

“This will strengthen us to monitor the forest ourselves. To be part of it and show we are not lazy”

“It’s our life, we live in the forest. We can watch over it. It’s our forest, and other people benefit from it”

“We would like our children to see these animals long into the future”

Just being given the chance to have a say in the future of their forest (let’s remember the Baka have lived successfully in these forests for at least 70,000 years), not even a promise of action yet but the very act of consulting them, brings much joy and gratitude and reminds me of why this is the only way conservation here will work.

Gaining the trust of communities leads to much more open and frank discussions. Through this, and engaging with law enforcement officers, it’s clear that the level of corruption is severe, with the very people responsible for trialing poachers and overseeing the process sometimes at the head of organising such activity. Tactics will therefore have to involve the collection of hard evidence by communities (the eyes and ears), accumulating this, and taking it the bosses of the bosses with a healthy dose of international pressure.

But in any case, the focus for now is to get the technology slick and discuss the final details with the communities, after-which we can introduce the phones, get reports streaming in, and reinstate indigenous rights whilst securing the biodiversity of Cameroon at the same time! (Good to remain optimistic, right?)

The future is African

The whole basis of my work in Cameroon, and of the work that ExCiteS does, is to empower local communities, enabling them to have a say in conservation.

For me, this means consulting with Baka hunter-gatherer and Bantu farming communities who reside inside and nearby the rainforests of the Congo Basin, asking these community members themselves as to what their imminent issues are and whether our data collection and reporting app Sapelli might be of use.

Promoting this essential idea of community participation is best done by other local people. This means that well-trained local people with experience in social and environmental anthropology are essential for sustainable resource-use and effective conservation in Africa. Unfortunately, local people who tick this box is far too few. Aiming to change this, however, is the Centre of Social Excellence, based both in Cameroon and Indonesia.

The inspiring, beautifully made, and highly informative film below explains their work and the importance of training African leaders for the future of their continent.

“The gorillas are eating our bananas”

The second and final part of this Cameroonian voyage has taken us to another reserve – Deng Deng National Park (see posts below for a catch-up).

But first we travelled from Yaoundé (the capital) to Lomié, a small town to the east of the Dja Biosphere Reserve (DBR). On our last trip a couple of weeks ago we visited indigenous Baka and farming Bantu forest communities to the south of DBR, but thought we could also try our luck to the east.

Choosing to work in the rainforest comes with some inevitable annoyances – it rains everyday once or twice and often really heavy, meaning that getting to some communities is pretty tough (even in the ZSL 4×4); there’s mosquitoes eating you all day as well as lots of other little plasma-sucking, blood-curdling, wasps-as-big-as-your-thumb flying things; there’s almost always only one meal on offer at the local eatery, so you either eat it or fall back on your secret supply of delicious but horribly sweet Boost bars from Sainbury’s.

In Lomié most of these were true, and we were two hours late for a meeting with a Bantu community due to heavy rain and pools of mud to cross through the forest. They weren’t too impressed. To be fair, everyone’s late to everything here, but I think two hours was slightly overdoing it… The other two communities we visited though were interested in our idea of developing an app with them through which they can monitor and report poaching in the forest (one applauded after my speech about the app, and the other erupted into song and dance).

A rewarding moment occurred when sitting outside the hotel and local guy starting trying to talk with me in English. After a bit of the ol’ chit chat, he turned to me said “I’m very happy”. I replied “What are you happy about?”. “I’m very happy that you Englishman are here in Cameroon. That you have come to our country.”

We headed north to Bertoua, the capital of the East Region in Cameroon, where we met up with Virginia, a Spanish woman working for a French NGO who knows the Deng Deng region well. She warned my ZSL colleagues and I that this would not be easy – in terms of poaching all the villages are in on it, they don’t care about conservation, and the local law enforcement does nothing. Interesting.

Over the next three days we arranged and carried out meetings with five Bantu communities around the national park. These went surprisingly well with concerns including help with reporting illegal activity and gorillas raiding their banana crops; I was half expecting the villagers to either fall asleep, walk out, or reject everything we were saying about conservation, but actually they were quite engaged. However this might have just been because we had an eco-guard with us, who’s job it is to protect the park and stop illegal activity. In any case, they prepared feasts of fish, manioc wrapped in banana leaves, and rice for us and we will likely go back and revisit at least a couple of the villages to work on developing the anti-poaching app. It’s easy to think of poachers as horrible people who don’t care about anyone or anything, however the villagers we met here were perfectly friendly and poaching not because they hate wildlife but because they have find themselves in an exceptionally difficult situation through which selling bushmeat can provide an answer.


A key problem here is that we do not want villages, which lie very close to one another, to report each other for poaching. It’s easy to see how this would result in conflict between villages and only worsen relationships which should be being strengthened for networking. Given that they all poach, the reporting would have to be of outsiders to all the communities, though as to how these would be identified is tricky.

Additionally, the villages around Deng Deng are in an increasingly uncertain situation. The park itself was created in 2010 as compensation for the huge hydroelectic dam constructed nearby. I’m all for renewables, of course they are the future (and should be the present) of energy, but hydroelectic dams do bring huge environmental costs – costs to ecosystems and species which are aiming to be saved by reducing climate change through building hydroelectric dams (see the irony). And this one has flooded a huge area of primary rainforest, which is now being grossly overfished by an influx of 10,000 people from neighbouring countries, who also chop down the forest to smoke the fish, getting ever closer to the ground of Great Apes, to whom they could spread diseases. Difficult for villages though is that they are trapped between this national park (no hunting, gathering or fishing), and other managed zones (forest management units and community forests), severely restricting their space for farming.

As an incredible highlight, and important reminder of why we are doing this work at all, we stumbled across two gorillas crossing the forest path one evening


Over the 13 communities we have visited in total over the last month, we’ll now need to decide which to work with. As I am working for ExCiteS, the UCL research group developing an app to empower marginalized communities to engage in conservation, my priority is to work with the indigenous Baka groups. Talking to them over the past month has been both inspiring and saddening, but I remain confident that based on their openness to work with us, we can restore at least a tiny bit of their pride, confidence, and governance over the forests of their ancestors. But for now, back to London.

Forest peoples, cow skin soup, and extreme citizen science

The indigenous Baka hunter-gatherers of Cameroon represent one of the oldest lineages of the human species. They are members of a central African group often referred to as ‘Pygmies’ due to their short stature, with recent genomic studies finding a lack of genes known to result in tallness in Europeans, as well as genes enabling the Baka to neutralise and digest harmful plant toxins found in central African rainforests¹.

Having inhabited the Congo Basin for such an extended period, the Baka have incredibly in-depth and diverse indigenous knowledge of the geography of these forests and the myriad species which survive here². Most Baka people now live near to roads interweaving the forest, within short distances from Bantu farmers settlements, largely a result of being forced out of the forest by the government’s National Zoning Plan (handing large parts of forest over for logging and mining concessions), and to create people-free conservation reserves. That’s right, there is a dark side to some conservation NGOs³.

The rich local knowledge the Baka have accumulated over thousands of years, as well as the continuous marginalisation and abuse they suffer from the authorities and Bantu farmers makes them perfect partners to develop a way in which they can take back some control in the use and monitoring of their ancestral lands. Technically they have hunting exceptions through so-called ‘users rights’ and can enter ‘community forests’, but these can be small areas, not necessarily in the same regions as ancestral hunting grounds, and indeed the Baka are sometimes targeted as illegal hunters none-the-less. Enter ExCiteS.

Last week, four ZSL colleagues and I travelled to the Dja Biosphere Reserve, a UNESCO World Heritage Site in southern Cameroon to try and identify villages  who might be interested in working with us in participatory mapping and reporting of illegal poaching. This area suffers severely from the illegal wildlife trade, including the hunting of gorillas, chimpanzees, forest elephants, pangolins, and pythons. Samuel, the social officer, already had a good idea of where different villages were which we could approach – a total of 8 including both Baka and Bantu, as well as those with both Baka and Bantu. Important to remember is that Bantu villages also rely heavily on forest resources and so suffer from illegal activity and restricted users rights.

In order to set up meetings with each community, we started by greeting the chief of each village, introducing ourselves, and arranging a date a time to return. Meeting five village chiefs on the first day one after another, one involving spontaneous dancing, was for sure an interesting experience… (the chief below insisted that I share his chair at the front).


Communities were generally very interested and listened intently as we discussed village characteristics, livelihoods, subsistence, associations etc. We had to be careful when introducing the ExCiteS anti-poaching technology, as local people are not necessarily completely against such short-term benefits. This was judged by inquiring as to how often they go into the forest, what resources they exploit, how species abundances have varied, and what their thoughts are on any outsiders entering the forests. Fortunately, almost all of the villages recognised a problem with outsiders (poachers) entering the forest, and queried as to how they can take more control. One Bantu village had concerns over who to report on, and the neighbouring Baka village could not be approached about the app due to marginalisation by the Bantus. If things went well though, the meeting would end with the community keen to take part and awaiting our next move.


Some Baka expressed very vocally as to how they have been promised many things by NGOs in the past and never heard another word. This was particularly difficult to answer as we too will unlikely be able to work with every village, but even for those we felt strongly that we’d like to revisit, making concrete promises is definitely a bad idea. In the end the only thing we could do is reassure them that we’ll return (to those selected), and that will be the evidence of our commitment.

Over the next week of meeting more communities, greeting local authorities, eating endless ndole, maize mash, and mysterious meat (including cow-skin soup), and enduring Britney Spears playlists (that was unexpected), we visited all 8 communities and had made some valuable contacts (there’s also some great local music like this and this). Now we’ll need to decide which to re-visit next time and continue the Free, Prior, and Informed Consent (FPIC) process before the app is introduced.


What sticks in my mind the most was talking to the Baka communities (through two translators). Sitting around their small round houses made of leaves, mud, and branches and hearing their stories of how they use the forest, how they’re so bitterly angry with outsiders taking their resources, how they often work for Bantu farmers for little pay and poor treatment, but yet greet us warmly and share a smile and laugh certainly inspires a lot of hope in me. In one village children were crying as they saw me, likely the first white person they’ve ever seen, and adults were nervous, but on leaving we shared a roar of laughter as I hit my head on the roof of their tiny shelter.

Why, What, When, How, Pizza


To get you quickly up to speed:

I’m working as a researcher with the Extreme Citizen Science Research Group (ExCiteS) at University College London (UCL), who:

“bring together scholars from diverse fields to develop and contribute to the guiding theories, tools and methodologies that will enable any community to start a Citizen Science project to deal with issues that concern them. With an interdisciplinary research approach we aim to provide any user, regardless of their background or literacy level, with a set of tools that can be used to collect, analyse and act on information according to agreed upon scientific methods”

The current project is in collaboration with the Zoological Society of London (ZSL), working in the southeastern rainforests of Cameroon. In this region the grossly marginalised Baka hunter-gatherers are in conflict with poachers who are rapidly depleting the forest resources and biodiversity (including chimpanzees, gorillas, pangolins, and pythons) which the Baka rely on. Local Bantu farming peoples also rely on such forest resources. Our aim is to create an app, called Sapelli, which will empower the indigenous peoples and local communities (ILCs) to report illegal wildlife trade activities, based entirely on what the communities want to report, and how they want the information they collect to be used – this is participatory monitoring. The app has already been trialed in the Congo.


Borders in general are not particularly great places to be. African boarders must be surely some of the most sketchy in the world, and my experiences in Mozambique and Zimbabwe have more than earned this title. Cameroon, however, was much more positive. “You are welcome” is what greeted me from the boarder guard after checking my passport. A good start.

Yaounde is expectedly hectic, with insane drivers and people all over the streets throughout the day and night. The ZSL office is in a weird, slightly-gradeoise building, that looks like it might have housed an elderly, powerful woman at some point. The staff are great and very knowledgeable, all of whom are Cameroonian bar three. Unfortunately the wi-fi is not quite up to the same standard (except in my excellent hotel room).
Slightly less expected was the quanity of pizza. I’ve only been in Yaounde itself for 3 days and already had the same number of pizzas (one good, one bad, and one which could not be called a pizza). This has mainly been when eating with the ZSL staff so perhaps they’re trying to settle me in gradually.

In terms of the work, so far its just been many many meetings so not too much to share. The staff here are certainly keen to see if our anti-poaching app (called Sapelli) could work here and have christened me as the ‘ExCiteS expert’, insisting that I take ‘VIP’ rooms and get cheuffered everywhere.

When we try and meet with Baka and Bantu forest communities around the Dja Biosphere Reserve next week, that’ll be when we can really get an idea of whether the project might work or not. It has to be done very carefully though; it’s not just the ‘bad guys’ from outside communities that are engaged in poaching, but also those from within communities and indeed other bodies who are supposed to be protecting wildlife. The illegal wildlife trade can provide short-term economic benefits to local people even if the long-term losses are far more severe. So, turning up and declaring we’ve come to help them stop the people who are stealing away their livelihoods (in terms of forest resources) isn’t guaranteed to always go down swimmingly. At this stage, therefore, our aims are centred on understanding community relationships, community issues, and building community trust.

‘Community Surveillence Networks’ (CSNs) are systems set up by ZSL already in various communities whereby community members can report any poaching activities they witness in the forests their villages encircle by ringing ZSL using a coded identity, afterwhich ZSL will notify the relevant law-enforcement authorities (namely la Ministre de Foret et de la Faun). CSNs may act as a stepping-stone for seeking out communities which are keen to be involved with Sapelli. Village Savings and Loans Associations (VSLAs), another scheme set up by ZSL where villages can meet together once a week to create a savings system, may well also act as a priceless platform through which to get communities together to discuss ideas of forest resources, monitoring, and using Sapelli.


To get a look at how these VSLAs work in person, Samuel (social officer), Simeon (community coordinator), and I went over to Lake Ossa in the west of Cameroon (next to the Gulf of Guinea) where the ZSL team there have been working on this. The lake is gigantic and well-fished by locals as a primary means of sustenance, though additionally relying on palm fruit and oil from the ever-expanding palm-oil plantations around the area. As well as attending calm and not-so-calm meetings with communities and chiefs (in French), we also got some time off to explore the lake and eat some amazing fried plantains (and not so amazing bitter-kola nuts)
