Social Correlates of and Reasons for Primate Meat Consumption in Central Amazonia

Hunting practices in southwestern Amazonia: a comparative study of techniques, modalities, and baits among urban and rural hunters

BACKGROUND

Hunting is a vital means of obtaining animal in various human populations. Hunters rely on their knowledge of species ecology and behavior to develop and employ hunting techniques and increase their chances of success. The comparison of the hunting practices of different human societies can shed light on the sustainability of hunting and the impact it has on species' populations. In this study, we examine and compare the techniques, modalities, and baits used by urban and rural hunters in Rondônia, a state in southwestern Amazonia, Brazil. We expected that rural hunters would use these elements and have greater knowledge when compared to urban hunters. We also expect that the use of specific hunting techniques and modalities will have greater selectivity and specificity of capture for rural hunters and that this knowledge will differ between groups.

METHODS

We conducted 106 semi-structured interviews with rural and urban hunters from October 2018 to February 2020. We analyzed the data using PERMANOVA and Network analyses to compare and contrast the hunting practices of each group.

RESULTS

We recorded four main hunting techniques divided into ten modalities with three techniques and seven modalities being the preferred choices among hunters. Waiting for at a Fruit Tree was cited as the primary technique employed by hunters living in urban and rural areas indicated. While the techniques and modalities were similar among hunters, the composition of species targeted and baits used differed between groups. Our network approach showed that modularity in urban areas was numerically lower than in rural areas. All species had one to more techniques associated with their capture.

CONCLUSIONS

Hunters living in urban and rural environments showed high similarity in their practices, probably due to sharing similar environments to hunt containing similar species, as well as targeting preferably the same species.

Rural–urban mobility influences wildmeat access and consumption in the Brazilian Amazon

Research demonstrates substantial urban consumption of wildmeat and the existence of trade networks in the Brazilian Amazon. Yet rural–urban mobility persists in this urbanized region, with the circulation of people, goods and ideas, blurring boundaries between rural and urban lives. Here we examined the relationships between rural–urban mobility and wildmeat access in highly forested areas of central Brazilian Amazonia. We surveyed 798 urban households in four towns and 311 rural households in 63 riverine communities. Rural–urban mobility was common amongst urban households: 49.7% maintained rural livelihoods and 57.3% were headed by rural in-migrants. Although many urban consumers purchased wildmeat, gifting was equally important. Urban households with greater rural–urban mobility consumed more wildmeat and were less likely to purchase it. Buying wildmeat was rare in rural areas but emergent in larger rural communities. Rural consumption was greater in remote areas, non-floodplain communities and during the high-water season. Urban populations placed particular pressure on three preferred species: the lowland paca Cuniculus paca, tapir Tapirus terrestris and white-lipped peccary Tayassu pecari. Rural consumption was more diverse, and per-capita wildmeat consumption was four times greater in rural than urban households (21 vs 5 kg/person/year). Total estimated annual wildmeat consumption was 3,732 t across 43 riverine urban centres compared to 11,351 t in surrounding rural areas. Because of poverty in these towns and socially mediated wildmeat acquisition, it is debatable whether urban consumers should or could be denied access to wildmeat. Nonetheless, the probable future increase in urban demand and related risks to sustainable, equitable resource use necessitate the monitoring and management of rural–urban wildmeat flows.

Wild meat trade over the last 45 years in the Peruvian Amazon

The trade in wild meat is an important economic component of rural people's livelihoods, but it has been perceived to be among the main causes of the decline of wildlife species. Recently, the COVID-19 pandemic has brought to light an additional concern of wildlife markets as a major human-health challenge. We analyzed data from the largest longitudinal monitoring (1973-2018) of the most important urban wild-meat markets in Iquitos, Peru, to examine the trends in and impacts of these markets on people's livelihoods. Over the last 45 years, wild meat sales increased at a rate of 6.4 t/year (SD 2.17), paralleling urban population growth. Wild meat sales were highest in 2018 (442 t), contributing US$2.6 million (0.76%) to the regional gross domestic product. Five species of ungulates and rodents accounted for 88.5% of the amount of biomass traded. Vulnerable and Endangered species represented 7.0% and 0.4% of individuals sold, respectively. Despite growth in sales, the contribution of wild meat to overall urban diet was constant: 1-2%/year of total meat consumed. This result was due to greater availability and higher consumption of cheaper meats (e.g., in 2018, poultry was 45.8% cheaper and was the most consumed meat) coupled with the lack of economic incentives to harvest wild meat species in rural areas. Most wild meat was sold salted or smoked, reducing the likelihood of foodborne diseases. Community-based wildlife management plans and the continued trade bans on primates and threatened taxa may avoid biodiversity loss. Considering the recent COVID-19 pandemic, future management plans should include potential viral hosts and regulation and enforcement of hygiene practices in wild-meat markets.
