Do cultural taboos regulate hunting in transitioning Indigenous communities? The case of the Idu Mishmi of Northeast India

People and Nature, EarlyView.
Abstract There is rising recognition of resource‐use rights of Indigenous Peoples and Local Communities (IPLCs) within wildlife conservation. Historically, sociocultural institutions ensured wildlife sustainability in many IPLC areas. However, the future viability of such institutions is uncertain as IPLCs change in response to external pressures and ...
