The Bushmeat Research Programme at the Institute of Zoology is involved in research to enhance our understanding of the bushmeat trade in West and Central Africa.
Bushmeat is the meat of wild animals hunted by local people for income or subsistence in West and Central Africa. The harvest of wild meat is a focus of global concern. Unsustainable levels of hunting are believed to threaten the survival of many target species around the world, particularly in the Tropics. These extinctions will not only threaten ecosystem services but are also likely to seriously impact upon the food security and livelihoods of those people who use this resource. There is therefore an urgent need to develop successful initiatives that will promote the long-term sustainability of the bushmeat harvest - both to protect threatened biodiversity and to secure the trade’s social and economic values.
The Bushmeat Research Programme at the Institute of Zoology is involved in research to enhance our understanding of the bushmeat trade in West and Central Africa. A better understanding of the trade will assist both policy makers and project managers to develop effective methods of regulation and management for sustainability. This work is interdisciplinary in its design: it tackles the biological, economic and social aspects of the trade, using a variety of approaches including field research and mathematical modelling.
There are a range of projects in the Programme, which are described here. This work encompasses several countries in the region (including Cameroon, Democratic Republic of Congo, Equatorial Guinea, Ghana, Nigeria, and Sierra Leone), and involves collaboration with a variety of institutions in both the host countries and in the UK. Our UK collaborators include colleagues at Cambridge University, Durrell Wildlife Conservation Trust (DWCT), Imperial College London, University College London (UCL), and the Wildlife Conservation Research Unit (Oxford University). This work has received funding from several sources including Conservation International, the Darwin Initiative, the Economic and Social Research Council (ESRC), and the Natural Environment Research Council (NERC).
The Bushmeat Research Programme is one component of ZSL’s overall bushmeat work. Through a combination of field projects, applied research, policy work, and education activities, this programme aims to protect habitats and wildlife through the management of the bushmeat trade to achieve long-term sustainability.
Bioeconomic modelling of bushmeat harvesting systems
This project aims to develop a general model of a bushmeat harvesting system that combines field data with a mathematical model to simulate bushmeat hunting patterns. The model is built on simple, proven principles that realistically describe the behaviour of hunters and the population dynamics of their prey in a multispecies community. Since the model predicts how different cost-benefit conditions for hunters can determine their hunting behaviour, and therefore the dynamics of prey populations, it can be used to explore the effects of future policy and management on long-term patterns of hunter profit, species offtake and sustainability.

Trade and sustainability along a bushmeat commodity chain (Ghana)
This project aims to describe the social and economic processes that drive the bushmeat commodity chain from harvesting to market sales. This work focuses primarily on market traders, but also encompasses detailed analyses on farmer hunters, commercial hunters, wholesalers and chop bars, and the different relationships between these actors. The commodity chain under study supplies the coastal city of Sekondi-Takoradi, Ghana’s third largest city.

Park protection, armed conflict and the bushmeat trade (Democratic Republic of Congo)
This study investigates patterns of prey availability, hunter offtake, household bushmeat consumption/sales and market dynamics, in and around Garamba National Park, Democratic Republic of Congo. It presents a detailed picture of the long-term dynamics of a bushmeat harvesting system around a protected area. In addition, this study also illustrates both the relative efficacy of protected area management and the potential impacts of military conflict on local bushmeat harvesting systems.

Incentives for the sustainable hunting of bushmeat (Equatorial Guinea)
Hunters are the crucial link between bushmeat supply and demand. This study follows an entire bushmeat supply chain in Equatorial Guinea, from forest to market, with a focus on hunter incentives. It considers the causes (consumer demand) and effects (changes in prey populations) of hunting, and how this affects hunter behaviour and decision-making, both in terms of livelihood options and prey choice. Fieldwork was undertaken in and around Monte Alén National Park, the village of Sendje, and the city of Bata.

Simple indices of hunter effort and sustainability (Equatorial Guinea)
This project looks at hunter decision making and the impacts of hunting on prey populations, in particular investigating the spatial dynamics of bushmeat hunting and the development of simple tools that might allow these impacts to be assessed indirectly without the need for difficult and expensive population monitoring.

Solutions to bushmeat exploitation in the Sanaga-Cross region (Cameroon-Nigeria)
This project adopts a spatially-explicit approach to study bushmeat supply and demand in the Sanaga-Cross region of Nigeria and Cameroon. By incorporating species biology and landscape ecology with household nutrition and market surveys, this work will develop a comprehensive understanding of the large-scale patterns and processes involved in the bushmeat trade.

Habitat quality and bushmeat surveys (Sierra Leone)
This research builds on detailed ecological studies in the Gola Forest Reserves, where the population densities of antelopes and primates were examined in unlogged and logged forests, cacao plantations and farmbush fallows, in which hunting pressure differed. A complementary set of data were gathered through hunter surveys on the edge of the forest reserve, and with market surveys in the nearest large town: Kenema. By combining these datasets, it has been possible to look at patterns of bushmeat trade and mammal depletion.

Bushmeat, poverty and rural livelihoods (Ghana)
This project aims to understand the role of bushmeat in the economy of rural Ghana, from an anthropological and development perspective, focussing on a cocoa-growing community in a forested part of the Western Region.

Fruit bats as bushmeat (Ghana)
Fruit bats are widely eaten, and yet surveys of mainstream bushmeat trade chains rarely feature these species. This set of projects aims to focus on the separate commodity chains by which bats are traded and consumed in key parts of West and Central Africa, currently beginning in Ghana and the Gulf of Guinea islands.

Monitoring international bushmeat trade – imports to Europe
While there is anecdotal evidence for substantial trade in bushmeat in Europe, we know very little about the scale and operation of this trade. This project aims to address this information gap through rigorous surveys of illegal imports at airports and surveys of traders in European cities. This study is ongoing.

Species vulnerability to bushmeat hunting
Susceptability to hunting pressure can vary dramatically between different species. This study explores these patterns of variation, and the mechanisms that might underpin such variation, in primates. It also investigates how the same taxa respond to other anthropogenic threats, namely selective logging and shifting cultivation.

Large-scale economic and environmental drivers of bushmeat trade (Ghana)
This study is analysing a 30 year dataset of bushmeat market flows in Kumasi in combination with data on climate and vegetation cover, and social research on household decision-making. The goal is to understand the large-scale forces driving unsustainable hunting in Ghana in order to guide policy response. This study is ongoing.
Roads and bushmeat trade in Gabon
Roads are a key factor in the bushmeat trade through their provision of access to markets. This study is examining in detail how this facilitation of trade operates in Gabon, focusing on how both the creation and deterioration of roads influence trade and livelihoods. This study is ongoing.
