Taking of Animals for Domestic Wild Meat Consumption a Major Threat to Species Protected by the Convention on Migratory Species
Among its findings, the report found that wild meat is often a key use and a major driver for legal and illegal hunting, particularly of ungulates and primates, and especially during times of conflict or famine and in the course of land-use change. This has led to drastic declines and extinctions of several migratory terrestrial mammal populations.
- 70% of hunted CMS terrestrial mammal species are used for wild meat consumption.
- Taking for domestic use is a larger concern than international trade for most CMS terrestrial species
Overall, 34 of 99 species with an IUCN Red List Assessment were reported as used at the subsistence level (direct use), 27 were traded nationally, and 22 were traded internationally, when all types of use were considered. However, when only meat for consumption was considered, 27 species (out of 99) were reported as consumed for subsistence, 10 species for national wild meat trade and only two species for international wild meat trade.
- There is strong evidence that zoonotic disease outbreaks are linked to human activities. Wild meat taking and consumption has been identified as the direct and causative agent for the spill-over into humans for Monkeypox virus, SARS, Sudan Ebola virus and Zaire Ebola virus, with subsequent human-to-human transmission.
- In total, 60 zoonotic viral pathogens were reported as hosted by the 105 migratory species studied.
- Encroachment into remaining intact habitats through infrastructure and economic activities have made vast new areas accessible for wild meat taking, thus increasing the zoonotic risk by bringing humans in contact with hitherto undisturbed host and pathogen populations.
The study cited a number of factors for the unsustainable taking. First, national legislation and regulations may lack clarity or are outdated, not reflecting the actual requirements of environmental factors, population traits and dynamics of the species concerned. Second, poor enforcement is a key driver of unsustainable use in several regions. Third, civil conflict and land-use change can drive increased taking for wild meat. Fourth, migratory animals cross countries and regions with a wide variety of differing laws and enforcement approaches, increasing the risk of unsustainable take at different stages of their migration. Finally, growing urbanization and increased sale of wild meat as a luxury product is an additional pressure on protected animals.
The report also found that seasonal migration patterns mean migratory species are a particularly susceptible target for hunters, poachers and other consumers due to the well-known timing of the species’ arrival in a particular area.
It is important to note that wildlife contributes to the food security, health, income, jobs and cultural identity of many rural economies and for some of the world’s most vulnerable Indigenous Peoples and Local Communities (IPLCs). Any policy response needs to consider such uses, as well as the drivers of food insecurity.
Most Species in the Study Are Reported as being Threatened by Hunting.
Hunting (for all purposes) is reported as a key threat to the survival of many species. Excluding bats (Chiroptera), the study finds that 98% (41 out of 42) of the CMS species with an IUCN Red List Assessment are threatened by hunting. Hunting threatens 95% (21 out of 22) of those that are classified by IUCN as Endangered, Critically Endangered, or Extinct in the Wild.
The study documented linkages between hunting and the declining population trends of several species. 77% (40 out of 52) of the CMS species that were assessed by IUCN as having decreasing populations were recorded as threatened by hunting in this study. For instance, most migratory ungulates still extant in the wild have experienced significant population declines that can be attributed to hunting. All chimpanzee subspecies and three of the four gorilla subspecies reported as significantly threatened by hunting are also experiencing large population declines. Overall, the assessment of the report finds that taking has a direct impact on the populations of more than half (58 out of 105) of the studied species, with high impacts for at least 42% (40 out of 105) of them.
The study also found that there is insufficient data for a conclusive assessment on the taking of bats, which make up half of the CMS terrestrial mammal species studied. This could signal that they are either infrequently hunted, or that their hunting is being underreported.
Most Hunted Species Are Used for Wild Meat Consumption
Wild meat is often reported to be the key use of terrestrial migratory species and a significant motive behind both legal and illegal hunting. This is of particular relevance for migratory ungulates and primates that suffer most in the context of human-related disasters such as conflicts and famines, but also in the case of land use change. The report found that of all the CMS terrestrial mammal species that were recorded as hunted, 70% (47 out of 67) are used for wild meat consumption. Illegal hunting for meat is the primary threat to three Gorilla subspecies, Western Lowland Gorillas (Gorilla gorilla gorilla), Grauer’s Gorilla (Gorilla beringei graueri) and the Cross River Gorilla (Gorilla gorilla diehli).
Carnivore and elephant species are hunted for many different uses and disaggregating the impact of wild meat hunting from hunting for trophies or human-wildlife conflict is often not possible.
Demand for Wild Meat as a Luxury Item Expected to Increase with the Growth of Urbanization
While wild meat can be an important source of nutrition for rural communities, wild meat does not often play a significant role in food security for urban dwellers, for whom it is a luxury item. Yet as urban populations grow, so does the demand for wild meat. Even low per capita consumption rates can add up to large total quantities of wild meat consumed, and urban demand is fueling increasing unsustainable offtakes in surrounding areas, contributing to heavier pressure on wildlife and a larger threat to the food supply of wildlife-dependent rural communities.
Available data shows that, for instance, the straw-colored bat (Eidolon helvum) in west and central Africa, and the chimpanzee (Pan troglodytes) in Cameroon and Nigeria have been available in large numbers across urban markets. Better transportation, availability of firearms and high financial incentives are amongst the drivers of increased urban access to wild meat.
Protection of CMS Terrestrial Mammal Species is Inconsistent
Most CMS terrestrial mammal species are protected to varying degrees under current laws, with levels of protection fluctuating across species and countries. In many tropical countries, urgent reform of current hunting legislation is needed. This includes subsistence hunting practices that are often incompatible with hunting regulations.
From several case studies, two themes emerged: first, while CMS species may be protected under national and international laws, in many countries enforcement capacity and effort is low, and unregulated hunting, therefore, continues unabated. Secondly, species populations that experienced sharp declines due to over-hunting have recovered after legal protection and the enforcement of laws.
Recommendations and Implications for the Future:
- Greater attention to domestic use and trade of CMS species is needed to address threats to conservation;
- National hunting legislation and regulations should be reviewed and updated as needed;
- Capacity for monitoring and enforcement should be examined and strengthened;
- The drivers contributing to the illegal or unsustainable use of wildlife for domestic consumption should be further identified and addressed;
- Understanding more about the spillover risks associated with wild meat use and trade, and the factors that might increase or decrease these risks, must be an immediate priority for wild meat research;
- Comparable and collatable data on hunting offtakes and species abundance should be gathered on all the species studied to enable more complete assessments of impacts of hunting for wildlife consumption and trade; and
- Additional international cooperation will be needed to address wild meat taking of migratory species, whose ranges span multiple countries.
