As human populations steadily improve, the habitat for wild animals is shrinking and violent conflicts between wildlife and individuals are changing into extra frequent. That is definitely the case with elephants in lots of elements of Asia, the place encroaching human populations have led to elephants raiding farmers’ crops and trampling fields to get to ancestral water holes.
Joshua Plotnik, an assistant professor of psychology at Hunter School in New York Metropolis, is an knowledgeable on elephant cognition and conduct and seeks to make use of these insights to assist mitigate these conflicts in Thailand and different international locations. In an interview with Yale Setting 360, he stresses the significance in conservation of moving into the minds of elephants, which, in distinction to people and different primates, rely closely on odor and sound to know the world. Plotnik additionally discusses how his work has proven elephants to be self-aware and empathetic creatures whose skill to suppose by issues rivals, and in sure respects exceeds, that of the nice apes.

“If we don’t perceive elephant conduct, we are able to’t give you good options for safeguarding them within the wild,” says Plotnik. “One factor is definite — if we would like elephants to live on within the wild, we’ve to guard habitat. We have now to verify elephants have the sources they have to be elephants.”
Yale Setting 360: How have elephant populations been faring in Asia and past?
Joshua Plotnik: Not properly. In Asia, some estimates say that there are 30,000 or 40,000 elephants remaining. In Africa, the numbers are seemingly between 500,000 and 700,000. In Africa, you have got had populations decimated by poaching largely because of a requirement for ivory merchandise. In international locations like Thailand, India, Sri Lanka, Bangladesh, and Myanmar, the most important downside is human-elephant battle. So whereas there’s sporadic poaching for ivory in Asia, as properly, and now a really scary commerce for different elephant physique elements, a lot of the issues contain loss and fragmentation of habitat, which is making it tough for elephant household teams to outlive.
e360: You’ve labored in Thailand. What’s the state of affairs like there?
Plotnik: In Thailand, you have got a authorities that cares very a lot about defending elephants, however the issue is individuals there have restricted entry to land, and the most effective obtainable land has been put aside for wildlife, so you have got rising ranges of battle. As their wild vary shrinks and extra individuals are transferring to the borders of nationwide parks, elephants, whereas typically searching for higher-quality meals, discover themselves inside farmers’ croplands.
This results in battle and typically to the dying of elephants and of individuals. Individuals typically die after they attempt to confront this huge, harmful, clever animal. It’s not shocking, when you have got two species that weren’t meant to share a habitat abruptly sharing one.
“By placing up an electrical fence, you’re not stopping the elephants from eager to get what’s on the opposite facet.”
e360: As I perceive it, the primary cause elephants raid crops is as a result of they’re hungry?
Plotnik: That’s one cause. What is basically fascinating to me is that I’ve heard studies, some from India, of elephants destroying crops with out consuming them. In order that is perhaps as a result of the depth of that battle is so excessive that the elephants are simply indignant, and they’re clever sufficient animals that I’d not be shocked in the event that they had been retaliating in opposition to individuals. We don’t have any exhausting, empirical proof for this but, however the number of battle throughout totally different landscapes makes this can be a scary risk. So once I hear tales like this I ask: Is it as a result of the elephants are hungry? Is it as a result of they’re indignant? Is it as a result of their habitat is fragmented?
e360: First it’s a must to discover out what the issue is?
Plotnik: That’s proper. It’s doable that if the elephants had different sources or a bigger space to reside in they won’t enter the cropland. So determining precisely learn how to deal with that is the tough half, and that’s the half that comes later. The primary half includes studying extra about elephant conduct, particularly when the elephants are in the course of these dangerous crop-raiding conditions. My future work in Thailand will contain observing elephants from watchtowers that we’re constructing to truly see how elephants are interacting with each other and with farmers in such conditions. If we don’t perceive elephant conduct, we are able to’t give you good options for safeguarding them within the wild.
e360: The methods we’ve been making an attempt to cope with battle between people and elephants previously haven’t all the time labored.
Plotnik: One of many most important methods up till now has been organising some kind of bodily barrier or fence to maintain elephants and people aside. This will assist in the brief time period. As a result of the state of affairs is so dangerous, we may have these short-term fixes to cease the escalation of the battle. However the issue is that they don’t work in the long term, as a result of they don’t handle the problem of why the elephants are doing this within the first place. By placing up an electrical fence, you’re not stopping the elephants from nonetheless eager to get what’s on the opposite facet of that fence. We wish to goal our mitigation methods to truly forestall battle, reasonably than simply protecting elephants and people aside.
“Elephants are acoustic and olfactory animals, and so they use these senses way more than the sense of sight.”
e360: Is there one thing that we are able to provide elephants that can induce them to behave as we would like them to and to remain out of hurt’s manner?
Plotnik: Effectively, we don’t have a terrific reply for that but. However the thought is that you just first must determine what the elephants need and wish— in some circumstances it is perhaps entry to bigger areas of land, it is perhaps entry to specific varieties of meals and water, entry to mates or different people inside their social group. What’s encouraging them to interact on this dangerous conduct? Should you discover out that they don’t have the meals they want, or their social group has been disrupted, then you’ll be able to give you administration strategies that treatment these conditions. Wildlife officers might doubtlessly present elephants with areas of land the place high-quality meals is made obtainable, or maybe give attention to creating corridors the place these elephants are evaded farmlands.
One factor is definite — if we would like elephants to live on within the wild, we’ve to guard habitat. That is the one resolution. We have now to verify elephants have the sources they have to be elephants.
e360: You research elephant cognition and intelligence. We all know that they’re sensible. Do we all know simply how sensible they’re?
Plotnik: I’ve been fascinated about designing experiments which are elephant-specific. One huge downside within the subject of animal cognition is that experiments are designed largely for visible species, like people, nonhuman primates like chimps or monkeys, and birds. These species are simpler for scientists to entry in labs. The design of a problem-solving field or a tool-use process for an experiment is commonly largely primarily based on paradigms that come from the primate or the human improvement literature.

The issue is for those who give these duties to animals that depend on non-visual senses, like canines and elephants, and so they don’t do properly, it’s very unfair to say that they aren’t as sensible as we’re, or they don’t have the identical cognitive capacities as we do. Possibly the take a look at simply isn’t proper for them. It’s not simple for us to place ourselves within the “sneakers” of those animals, as a result of we don’t have the identical sensory view of the world. Elephants don’t reside in the identical sensory world as we do. We’re extremely visible animals. Elephants are acoustic and olfactory animals, and we expect they use their senses of odor and listening to way more than they use their sense of sight. One of many ways in which elephants talk, for instance, is with infrasound, low-frequency sound that travels by the bottom. There may be thrilling analysis that exhibits that they’ll really detect this sound with their toes.
We additionally know that they typically make choices on the place to seek out meals with their sense of odor. They might use their trunks as a form of periscope to find meals sources over nice distances. If we are able to present how precisely elephants make choices about the place to go for meals and learn how to discover it, we might come to raised perceive why they raid crops, for instance, and we could possibly give you higher options to the human-elephant battle downside.
e360: What are a number of the issues that you just personally have realized about elephants by your analysis?
Plotnik: The primary research that I did with elephants demonstrated their skill to acknowledge themselves in a mirror, which we did in New York Metropolis on the Bronx Zoo. So far, solely elephants, bottlenose dolphins, nice apes, and one corvid [crow family] species, the magpie, have handed this take a look at. Mirror self-recognition appears to be linked to the capability for self-awareness, the power to acknowledge oneself as separate from others, which can additionally relate to empathy, the power to place oneself in one other’s sneakers emotionally. Elephants are recognized to behave to assist others when they’re in want, so this all is sensible.
“The large take-home message is that it’s a must to perceive the animal that you’re making an attempt to guard.”
The large take-home message right here is that it’s a must to perceive the animal that you’re making an attempt to guard, if you’ll achieve success in conserving it. Plenty of occasions these conservation methods should not profitable as a result of they fail to acknowledge the wildlife’s perspective.
e360: You additionally work to coach younger individuals about elephants.
Plotnik: Earlier than I joined the Hunter School school, I based a nonprofit referred to as Suppose Elephants Worldwide. We run conservation education schemes in the USA and Thailand, and hope to increase to different international locations like China quickly. We use the research of elephants as a hook to get youngsters extra fascinated about and to suppose extra critically about science, and to be extra acutely aware about how their choices will impression the atmosphere.
e360: What has your expertise been like with youngsters in Thailand?
Plotnik: Among the college students we taught come from villages the place individuals have died because of human-elephant battle. We had been working a program in central Thailand, for example, when a pupil got here as much as me and mentioned, “Ajarn [teacher], I really like my father very a lot, however my father is an ivory carver. Is he a nasty man?” That was a strong query. It made me suppose that we might have an actual impression on younger individuals. I informed him that his father wasn’t a nasty man; he was caring for his household. I steered that the younger boy take into consideration what he can do himself to assist elephants.
