Coronaviruses are a family of viruses that cause disease in animals. Covid-19 is one of several such viruses that have made the jump from animals to humans. So far, the evidence suggests that the virus was first transmitted to humans at a seafood market in Wuhan, China. The Wuhan seafood market also sold wildlife, but despite extensive experimental work, scientists are still not confident about the transmission chain from animal to human, with links drawn to snakes, bats and, more recently, pangolins. What is clear, however, is that there is now unprecedented global attention focused on wild meat trade and consumption globally.
The ongoing covid-19 crisis may be the first time many people have heard of wild meat, or “bushmeat” as it’s commonly known. Wild meat is meat from wildlife species that are hunted for human consumption. It constitutes a primary source of protein for many rural communities globally, particularly in tropical forests, where it contributes to the food security of millions of people globally. Across Central Africa, species hunted in rural areas are also sent to cities and large towns to satisfy the growing urban demand for wild meat. There, wild meat caters to both the growing number of upper-middle class customers who wish to consume high-value and sometimes rare species as a status symbol, as well as the urban poor who consume small species such as rodents which are often still less expensive than farmed animals. The drivers and impacts of hunting and consumption of wild meat are not homogenous, and should not be treated as such.
The impact of wild meat trade bans on people and conservation
In recognition of the importance of wild meat for food security and livelihoods, global conservation policy has focused on the need for sustainable use of species hunted for wild meat, and many experts agree that using wild species sustainably may still be the best way to save them. Yet, following the covid-19 outbreak, we are seeing a growing number of calls to ban the trade and consumption of wildlife globally.
The covid-19 outbreak has shown us that there is clearly a need to readdress our balance with nature. But, what lessons can we learn from past attempts at banning wild meat, and what are the possible realities for both conservation and for those who depend on wild meat for food and income?
- While some of the proposed bans recognize the important role that wild meat plays for the food security and nutrition of indigenous peoples and local communities globally, wild meat also constitutes an important financial backstop across Africa, in particular during low seasons or when agricultural commodity prices fluctuate. The Ebola crisis and subsequent ban on the trade of wild meat markets across West and Central Africa resulted in unemployment for thousands of women, the primary traders of wild meat. The potentially unequal effects such bans could have on the financial security of different groups of people must be properly considered. Livelihood alternatives must be co-designed and led by those who will be affected in order to mitigate such effects and ensure alternatives are locally relevant.
- If alternative sources of food and income are not provided for those who need it, bans on wild meat trade and consumption could result in malnutrition among the young and most vulnerable, or push the trade of wild meat underground and worsen contributing factors to the spread of disease. Following the 2013-2016 Ebola outbreak, a universal ban on wild meat markets was imposed across West Africa. Rather than being enforced, it pushed many wild meat markets underground, rendering regulation more complex and worsening food hygiene conditions, a key driver of disease spread. Further, past attempts to limit wild meat sales in Equatorial Guinea, were only transiently effective as the hunting ban was again not enforced and was quickly followed by a marked increase in wild meat hunting compared to hunting rates prior to the ban. Poorly considered bans resulted in the erosion of food security and health and unintended consequences for conservation, ending in calls for a more nuanced understanding of how future spillovers could be prevented.
- There is a common assumption that people in rural areas eat wild meat because they have no other alternatives. The Darwin Initiative project “Why Eat Wild Meat”, looks to understand individual level differences in wild meat preferences, hunting, and consumption and the reasons for doing so, in rural villages in southeastern Cameroon. The project is finding that yes, people eat wild meat because it is readily available to them, but also, and more importantly, because they like the taste. As such, it’s important that conservationists keen to devise protein alternative projects first understand why people eat and hunt wild meat. Alternatives are best when locally conceived, and when projects are co-designed, to ensure that subsequent alternatives meet local needs and have longevity.
- It is also often assumed that livestock or poultry present culturally viable alternatives to wild meat. However, the “Why Eat Wild Meat” study identified greater concerns by some local people in rural Cameroon over the health of domestic animals than they did over many species hunted for wild meat. This is due in part to several outbreaks of disease relating to domestic animals, including most recently avian influenza, and personal experiences of livestock or poultry falling ill. Additionally, animals such as chickens and goats are kept for sale or for large celebrations in these villages, and are not routinely consumed for subsistence purposes. As such, encouraging a shift away from hunting and towards a dependence on livestock and poultry would require a deep cultural shift for some rural communities.
- The impact of a shift to livestock or poultry raises concerns for many conservationists about deforestation; researchers estimate that if livestock such as cattle were to replace wild meat in the Congo Basin, 25 million hectares of forest would be converted to pastureland. Realistically, pigs or chickens would be seen as more viable replacements to wild meat, but again this would require an estimated additional 4.5 million tons of pigs or chickens, again unlikely to happen any time soon in the Congo Basin. We must consider the potential adverse impacts that calling for a shift to livestock could have, and whether such calls are realistic in the timeframe required.
We need local understanding
Much of the recent work on wild meat and disease has focussed on the international convention scale. If we are to change behaviours to protect against the emergence of further zoonotic diseases and encourage a shift away from any unsustainable or illegal behaviours, we must also have a local understanding of why people make the choices they do, as well as the pathways of trade and transmission, to help ensure that policy changes regarding wild meat are driven by evidence, and that subsequent actions are locally relevant and realistic. As the “Why Eat Wild Meat” project is discovering, the reasons behind wild meat hunting and consumption, the types of biodiversity involved in trade and the pathways for disease transition are complex and varied. So then, should be the proposed effective ways to tackle the spread of new diseases such as covid-19.
We must learn from previous crisis responses to climate shocks, disease outbreaks and humanitarian disasters, where hurried response interventions led maladaptation and further damages to lives, livelihoods, and the environment. We need greater efforts to understand these local contexts and drivers of wild meat hunting and consumption, if we are to change patterns of use.
