Human-Wildlife Conflict

Human-wildlife conflict arises when interactions between people and wild animals harm people, their livelihoods or wildlife. Around protected areas, its principal ecological causes are habitat loss and fragmentation, changes in food and water availability, and animal movements that bring wildlife into farms, grazing grounds and settlements.

Habitat loss and disrupted connectivity

A protected area's administrative boundary rarely encloses every habitat or movement route that its wildlife requires. Ecological changes outside it can therefore increase encounters even when the protected habitat remains relatively intact.

• Habitat loss through conversion of surrounding forests and grasslands reduces the space and resources available to wildlife while increasing contact with human land uses.
• Habitat fragmentation separates feeding, breeding and shelter sites. Animals moving between these patches may have to cross cultivated or inhabited land.
• Obstruction or narrowing of wildlife corridors concentrates movement through fewer routes, increasing encounters where these routes overlap with settlements and farms.

Declining or unevenly distributed natural resources

Conflict becomes more likely when animals must travel farther or leave secure habitat to meet their ecological needs.

• Habitat degradation and competition with livestock can reduce natural forage, encouraging wild herbivores to feed in nearby agricultural fields.
• Depletion of wild prey can encourage carnivores to take accessible livestock, although livestock predation does not always indicate prey scarcity.
• Seasonal water scarcity and drought can draw wildlife towards shared water sources, irrigated fields and settlements.

Normal movement and seasonal changes

Wildlife movement beyond protected areas is not necessarily evidence of habitat failure or excessive animal numbers. It can reflect ordinary ecological requirements.

• Species with large home ranges may regularly use habitats beyond reserve boundaries, bringing them into contact with surrounding communities.
• Dispersal, particularly when young animals seek new territories, can take individuals through unfamiliar, human-dominated landscapes.
• Seasonal changes in rainfall, vegetation and food availability alter animal movements; conflict can arise where these movements intersect with cultivation or settlement.

Attractive resources at the human-wildlife interface

Human-modified habitats may offer concentrated, easily accessible resources. Conflict can therefore result from attraction towards these resources, not simply from animals being pushed out of forests.

• Crops and stored grain provide food that can attract herbivores and other wildlife.
• Livestock, carcasses and food waste can attract carnivores or scavengers, increasing opportunities for encounters.
• Repeated access to such food can reinforce animals' use of human-dominated areas, making conflict recurrent.
