Human–wildlife conflict refers to the interaction between wild animals and humans, and the resultant negative impact on people, animals, resources, and habitats. It occurs when growing human populations overlap with established wildlife territory, creating competition for space and resources. Conflict takes many forms including but not limited to: loss of life or injury to humans and wild animals, depredation of livestock, and degradation of habitat. Human–wildlife conflict is a global issue present in urban and rural landscapes alike.
Previously, conflict mitigation strategies utilized lethal control, translocation, population size regulation, and endangered species preservation. Recent management now uses an interdisciplinary set of approaches to solving conflicts. These include applying scientific research, sociological studies, and the arts to reducing conflicts. As human-wildlife conflict inflicts direct and indirect consequences on people and animals, its mitigation is an important priority for the management of biodiversity and protected areas.
Human–wildlife conflict is defined by the World Wide Fund for Nature (WWF) as "any interaction between humans and wildlife that results in negative impacts of human social, economic or cultural life, on the conservation of wildlife populations, or on the environment. The Creating Co-existence workshop at the 5th Annual World Parks Congress (8–17 September 2003, Montreal) defined human-wildlife conflict in the context of human goals and animal needs as follows: “Human-wildlife conflict occurs when the needs and behavior of wildlife impact negatively on the goals of humans or when the goals of humans negatively impact the needs of wildlife."
A 2007 review by the United States Geological Survey defines human-wildlife conflict in two contexts; firstly, actions by wildlife conflict with human goals i.e. life, livelihood and life-style, and secondly, human activities that threaten the safety and survival of wildlife. However, in both cases outcomes are decided by human responses to the interactions.
The Government of Yukon defines human-wildlife conflict simply, but through the lens of damage to property, i.e. "any interaction between wildlife and humans which causes harm, whether it’s to the human, the wild animal, or property." Here, property includes buildings, equipment and camps, livestock and pets, but does not include crops, fields or fences.
Human-wildlife interactions have occurred throughout man's prehistory and recorded history. Among the early forms of human-wildlife conflict is the depredation of the ancestors of prehistoric man by a number of predators of the Miocene such as saber-toothed cats, leopards, and spotted hyenas.
Fossil remains of early hominids show evidence of depredation; the Taung Child, the fossilized skull of a young Australopithecus africanus, is thought to have been killed by an eagle from the distinct marks on its skull and the fossil having been found among egg shells and remains of small animals.
A Plio-Pleistocene horned crocodile, Crocodylus anthropophagus, whose fossil remains have been recorded from Olduvai Gorge, was the largest predator encountered by prehistoric man, as indicated by hominid specimens preserving crocodile bite marks from these sites.
Examples of Human-Wildlife Conflict
As a tropical continent with substantial anthropogenic development, the Africa is a hotspot for biodiversity and therefore, for human-wildlife conflict. Two of the primary examples of conflict in Africa are human-predator (lions, leopards, cheetahs, etc.) and human-elephant conflict. Depredation of livestock by African predators is well documented in Kenya, Namibia, Botswana, and more. African elephants frequently clash with humans, as their long-distance migrations often intersect with farms. The resulting damage to crops, infrastructure, and at times, people, can lead to the retaliatory killing of elephants by locals.
With a rapidly increasing human population and high biodiversity, interactions between people and wild animals are becoming more and more prevalent. Like human-predator in Africa, encounters between tigers, people, and their livestock is a prominent issue on the Asian continent. Attacks on humans and livestock have exacerbated major threats the tiger conservation such as mortality, removal of individuals from the wild, and negative perceptions of the animals from locals. Even non-predator conflicts are common, with crop-raiding by elephants and macaques persisting in both rural and urban environments, respectively.
The first instance of death due to human-wildlife conflict in Antarctica occurred in 2003 when a leopard seal dragged a snorkelling British marine biologist underwater because of which she drowned.
Human–wildlife conflict in Europe includes interactions between people and both carnivores and herbivores. A variety of non-predators such as deer, wild boar, rodents, and starlings have been shown to damage crops and forests. Carnivores like raptors and bears create conflict with humans by eating both farmed and wild fish, while others like lynxes and wolves prey upon livestock. Even less apparent cases of human-wildlife conflict can cause substantial losses; 500,000 deer-vehicle collisions in Europe (and 1-1.5 million in North America) led to 30,000 injuries and 200 deaths.
Instances of human-wildlife conflict are widespread in North America. In Wisconsin, United States wolf depredation of livestock is a prominent issue that resulted in the injury or death of 377 domestic animals over a 24-year span. Similar incidents were reported in the Greater Yellowstone ecosystem, with reports of wolves killing pets and livestock. Expanding urban centers have created increasing human-wildlife conflicts, with interactions between human and coyotes and mountain lions documented in cities in Colorado and California, respectively, among others. Big cats are a similar source of conflict in Central Mexico, where reports of livestock depredation are widespread, while interactions between humans and coyotes were observed in Canadian cities as well.
On K’gari-Fraser Island in Australia, attacks by wild dingoes on humans (including the death of a child) created a human-wildlife crisis that required scientific intervention to manage. In New Zealand, distrust and dislike of introducing predatory birds (such as the New Zealand Falcon) to vineyard landscapes led to tensions between people and the surrounding wildlife. In extreme cases large birds have been reported to attack people who approach their nests, with human-magpie conflict in Australia a well-known example. Even conflict in urban environments has been documented, with development increasing the frequency of human-possum interactions in Sydney.
As with most continents, the depredation of livestock by wild animals is a primary source of human-wildlife conflict in South America. The killings of guanacos by predators in Patagonia, Chile – which possess both economic and cultural value in the region – have created tensions between ranchers and wildlife. South America’s only species of bear, the Andean Bear, faces population declines due to similar conflict with livestock owners in countries like Ecuador.
Human–wildlife conflict is not limited to terrestrial ecosystems, but is prevalent in the world’s oceans as well. As with terrestrial conflict, human-wildlife conflict in aquatic environments is incredibly diverse and extends across the globe. In Hawaii, for example, an increase in monk seals around the islands has created a conflict between locals who believe that seals “belong” and those who do not. Marine predators such as killer whales and fur seals compete with fisheries for food and resources, while others like great white sharks have a history of injuring humans. While many of the causes of human-wildlife conflict are the same between terrestrial and marine ecosystems (depredation, competition, human injury, etc.), ocean environments are less studied and management approaches often differ.
Mitigation strategies for managing human-wildlife conflict vary significantly depending on location and type of conflict. The preference is always for passive, non-intrusive prevention measures but often active intervention is required to be carried out in conjunction. Regardless of approach, the most successful solutions are those that include local communities in the planning, implementation, and maintenance. Resolving conflicts, therefore, often requires a regional plan of attack with a response tailored to the specific crisis. Still, there are a variety of management techniques that are frequently employed to mitigate conflicts. Examples include:
- Translocation of problematic animals: Relocating so-called "problem" animals from a site of conflict to a new place is a mitigation technique used in the past, although recent research has shown that this approach can have detrimental impacts on species and is largely ineffective. Translocation can decrease survival rates and lead to extreme dispersal movements for a species, and often "problem" animals will resume conflict behaviors in their new location.
- Erection of fences or other barriers: Building barriers around cattle bomas, creating distinct wildlife corridors, and erecting beehive fences around farms to deter elephants have all demonstrated the ability to be successful and cost-effective strategies for mitigating human-wildlife conflict.
- Improving community education and perception of animals: Various cultures have myriad views and values associated with the natural world, and how wildlife is perceived can play a role in exacerbating or alleviating human-wildlife conflict. In one Masaai community where young men once obtained status by killing lions, conservationists worked with community leaders to shift perceptions and allow those young men to achieve the same social status by protecting lions instead.
- Effective land use planning: altering land use practices can help mitigate conflict between humans and crop-raiding animals. For example in Mozambique, communities started to grow more chili pepper plants after making the discovery that elephants dislike and avoid plants containing capsaicin. This creative and effective method discourages elephants from trampling community farmers' fields as well as protects the species.
- Compensation: Compensation: in some cases, governmental systems have been established to offer monetary compensation for losses sustained due to human-wildlife conflict. These systems hope to deter the need for retaliatory killings of animals, and to financially incentivize the co-existing of humans and wildlife. Compensation strategies have been employed in India, Italy, and South Africa, to name a few. The success of compensation in managing human-wildlife conflict has varied greatly due to under-compensation, a lack of local participation, or a failure by the government to provide timely payments.
- Spatial analyses and mapping conflict hotspots: mapping interactions and creating spatial models has been successful in mitigating human-carnivore conflict and human-elephant conflict, among others. In Kenya, for example, using grid-based geographical information systems in collaboration with simple statistical analyses allowed conservationists to establish an effective predictor for human-elephant conflict.
- Predator-deterring guard dogs: The use of guard dogs to protect livestock from depredation has been effective in mitigating human-carnivore conflict around the globe. A recent review found that 15.4% of study cases researching human-carnivore conflict used livestock-guarding dogs as a management technique, with animal losses on average 60 times lower than the norm.
Hidden Dimensions of Conflict
Human wildlife conflict also has a range of 'hidden' dimensions that are not typically considered when the focus is on visible consequences. These can include health impacts, opportunity costs, and transaction costs. Case studies include work on elephants in northeast India, where human-elephant interactions are correlated with increased imbibing of alcohol by crop guardians with resultant enhanced mortality in interactions, and issues related to gender in northern India. In addition, research has shown that the fear caused by the presence of predators can aggravate human-wildlife conflict more than the actual damage produced by encounters.
