By Henry Rees, CLP Programme Officer

Not long ago, when I was at a very early stage in my career, I had quite straightforward beliefs about biodiversity conservation. Back then, I saw very little overlap between the human and ecological worlds. My understanding of conservation was simply that these worlds should be kept apart where possible and that this was the only way to prevent further degradation. Now, with more hindsight, I can say with certainty that this view is limited.

Below I reflect on how broadening our perspectives, and finding a more holistic understanding of conservation as a system, could help us begin to unlock a healthier, more protected planet for future generations.

What do I mean by a ‘system’?

A system can be defined as “a collection of related components that interact with one another toward a greater whole and a common goal.” Early on in my career, I began to realize the power of systems-thinking: a discipline that helps us reveal the different components of a system and understand how they interact. Often used in other sectors like technology and engineering, it is now gaining traction in the conservation world, and it appealed to me as an effective tool for diagnosing problems that don’t have obvious, easy solutions.

The ‘blue jumper’ analogy helps to visualise a systems-thinking approach. You can ask: what components of a blue jumper come together to make the whole thing?

First, there are the threads, each of which is important and interwoven in such a way to give the jumper its unique structure. Other components are also at work. The blue dye and materials are also present and interacting. The jumper wouldn’t be the same without all of these different elements.

Employing systems thinking on our blue jumper may reveal previously undiscovered components and questions. Where were the materials sourced from? Where was it made? By whom? Why did they make it? And so on.

The list of components can be extensive, and some are more important than others. But, ultimately, if any of them are affected, then this could cause a chain reaction and dynamically affect the other components in ways you may never have thought possible. The blue jumper could be compromised for good.

Systems thinking and conservation

Starting to think about conservation as a system was a big turning point for me. I realised that using this approach opens up a range of seemingly infinite components that we can look at to find solutions to our most pressing environmental problems.

This realisation gave me hope, but it also helped me begin to comprehend the problems that we face. The systems in which we must intervene to protect biodiversity are complex, consisting of both ecological and social components.

Research has shown that if we wish to effectively intervene, we must first develop a holistic understanding of these components, including the varied needs, perspectives and values of the people involved.

As has been shown in conservation countless times before, intervening without considering these interacting values may lead us to fail in our mission to protect biodiversity.

Our actions may be linked to and have unintended consequences elsewhere in the system. Pulling one stray thread in your blue jumper may cause the rest of the threads to snag and eventually the whole thing will unravel.

Building a more complete picture of conservation

It is impossible for any one person to identify all of the hidden components of a system. They will only be able to recognise certain components and interactions that have some relation to their own perceptions and biases, which are informed by their unique life experiences.

So, the only way we can ever hope to achieve a holistic understanding of a system is by talking to and working with others.

As a programme dedicated to building the capacity of early-career conservationists, CLP works to achieve levels of collaboration not often seen in the conservation sector. We are a close partnership between three organisations (FFI, BirdLife and WCS) and we each have strong lines of communication and co-operation with one another.

Through our annual Team Awards, we fund and train exceptional conservationists leading applied biodiversity projects that seek tangible, long-term solutions to the world’s most pressing conservation challenges. Many of our alumni have gone on to deliver remarkable conservation impacts, most recently showcased in our latest annual report and in our News pages.

Each year, we host awardees at key events and at our regional and international training courses, where they get invaluable opportunities to meet peers and establish long-lasting friendships and potential collaborations.

This year, during the pandemic, we continued to form these important links in our first-ever online international Conservation Management & Leadership course, which has connected more than 30 conservation leaders from several countries including Kenya, Argentina, Georgia, Vietnam, Bangladesh, South Africa, India, Bolivia and Tajikistan (to name just a few!)

This year, CLP held its first-ever online international Conservation Management & Leadership course, which established links among conservationists around the world.

Collaborative thinking and action are key

We are all vital components of the systems in which we operate and we each see these systems differently. In this way, collaborative thinking and action are essential to understanding and combating the complex problems facing biodiversity. By taking the time to acknowledge and understand the perspectives of others, our alumni are able to build a more complete picture of their projects and the challenges they need to overcome. Only in this way can we not only keep our ‘blue jumper’ from unravelling, but also ensure the threads, and the connections between them, are strong and effective enough to last.

About the author

About a year ago, Henry Rees joined the CLP team as a Programme Officer at Fauna & Flora International (FFI) in Cambridge, UK. Before joining CLP, he had completed a BSc in Zoology and an MSc in Conservation Science and worked as a wildlife surveyor. Born and raised in London, he grew up in a family who instilled in him a deep love of nature. Working in conservation had been a dream that had motivated him for most of his life, but it wasn’t until he studied conservation formally that he began to view it as an interconnected system.

While the exact cause of the COVID-19 outbreak is still a matter of debate, the broad consensus is that at its origin is a coronavirus that occurs in wildlife (a zoonotic disease). There is also strong evidence to suggest that human actions enabled the causative coronavirus, SARS-CoV-2, to jump from wild animals to people.

In search of expert insights, we spoke to CLP alumnae, Iroro Tanshi and Dr Mariane Kaizer, who both lead conservation projects impacted by a zoonotic disease. Below they explain how human actions contributed to the disease outbreak, and why conservation efforts will play a vital role in preventing future pandemics.

COVID-19: A bat conservationist’s perspective

CLP awardee and bat specialist, Iroro Tanshi, has dedicated her PhD research and 2020 CLP project to saving the only known population of short-tailed roundleaf bats (Hipposideros curtus) in Nigeria. Thanks to her research efforts, the IUCN Red List has recently uplisted the species from Vulnerable to Endangered.

Yet Iroro’s vital work has been put in jeopardy since an ancestral version of SARS-CoV-2 was found in bats. Iroro and other bat conservationists are concerned that the misinterpretation of these findings will make people believe —very wrongly—that bats cause the spread of COVID-19.

Iroro notes substantial anecdotal evidence indicating the escalation of bat culling around the world, presumably due to the mistaken belief that it will curb the spread of the disease.

Iroro and her colleagues are fighting to prevent bat culling by stressing that it is people who transmit COVID-19 to other people, not bats. It’s also important to note that, while bats and other animals are known to harbour SAR-like coronaviruses, the exact mechanism that caused the virus to move from wildlife to humans (viral spillover) remains unknown.

According to Iroro, what is clear is that people played a key role in causing the outbreak. “Normally, the chances of a viral spillover event occurring are very, very low. But through our actions, we provided an already adaptable coronavirus with ample opportunities and the perfect conditions to flourish,” she said.

Iroro explains that the destruction of bats’ natural habitats and the wildlife trade are likely to have caused novel species interactions and increased human-wildlife contact, allowing the virus to spillover to humans. However, as the specific origin of the virus is still being investigated, it is unclear whether bats were involved directly or indirectly (via an intermediate host) or if there are other wildlife origins we don’t yet know about.

Irrespective of the origins of SARS-CoV-2, human actions are ultimately to blame for the spillover and community transmission. It is thus our responsibility to prevent such zoonotic outbreaks from happening again.

Yellow fever: Learning lessons from the past

In 2018, Brazilian primate expert Dr Mariane Kaizer led a CLP-funded project to raise public support for the conservation of endemic primate species in Brazil, including Critically Endangered northern muriquis monkeys (Brachyteles hypoxanthus).

At the time, Brazil was experiencing an epidemic of yellow fever (YF), an infectious disease caused by a mosquito-borne virus (for which non-human primates are the main reservoir of infection). The outbreak was spreading in both human and non-human primate populations throughout the south-east Atlantic forest region.

Mariane and her team set out to uncover how YF was affecting monkeys in the area. In the Caparaó National Park, they found dozens of southern brown howler monkeys (Alouatta clamitans) had died from YF. Another team working just 80 kilometres north in the Private Reserve Mata do Sossego found the illness had killed 26% of the northern muriquis population, which was a crippling blow to the already declining population.

But the monkeys here aren’t just at risk from YF. Along with illegal hunting, wildlife trade and habitat destruction due to deforestation, they are also in danger of being persecuted and killed by local people who mistakenly fear they cause the spread of diseases like YF.

Such actions are probably increasing the risk of YF outbreaks in people. Deforestation destroys the natural barriers that would otherwise keep infected mosquitos at bay. And, by entering forests to illegally hunt or capture monkeys, people are more likely to be bitten by infected mosquitos and carry them back to other people, such as in vehicles.

Now that there is an increased risk of YF and other zoonotic disease outbreaks, health authorities in Brazil have had to start relying on non-human primates as ‘natural sentinels’ in wildlife disease surveillance programmes. In the case of YF, the virus affects monkeys before it affects people, providing a vital early indicator of a potential YF outbreak in human populations.

Mariane believes that learning lessons from such well-documented cases and conservation projects could help us prevent future outbreaks of zoonotic diseases. “After the COVID-19 outbreak, it is now more vital than ever before to use what we have learned from past experiences (like in the case of the yellow fever epizootic in Brazil) to improve how we monitor and mitigate harmful zoonoses,” says Mariane.

Reinforcing the barriers against disease

To prevent future zoonotic disease outbreaks and protect nature, Mariane and Iroro are among many conservation leaders who are campaigning for change. Among the CLP partners, for example, two public petitions are calling on governments and the private sector worldwide – one to make living on a healthy planet a human right and another to pledge $500 billion in funding to local conservation groups around the world.

Moreover, there has been a call for a ban on the commercial wildlife trade that considers cultural and socioeconomic implications related to the traditions and food security needs of local people.

Across the world, it is clear that we must work together to prevent ecological degradation and restore natural habitats, prohibit nonessential hunting and the commercial wildlife trade, and establish comprehensive wildlife disease surveillance programmes. These changes could prevent future zoonoses and their potentially devastating impact on both people and wildlife.
