The hunting of wild animals for their meat has been a crucial activity in the evolution of humans. It continues to be an essential source of food and a generator of income for millions of Indigenous and rural communities worldwide. Conservationists rightly fear that excessive hunting of many animal species will cause their demise, as has already ha...
Article
Sustainability is widely used in science and politics and has myriad definitions. Some explanations emphasize the ecological, socio-political or economic aspects of sustainability. In this chapter we introduce the different approaches and metrics that have been used or proposed to assess wild meat sustainability. We first describe the concept of ma...
Article
