The stakeholder engagement methodology of 3MK recognises that the breadth of potential local impacts of mining on environments and societies requires care and transparency in the stakeholder engagement process. It therefore highlights a commitment to co-construction of knowledge that includes involving experts from relevant industries and government agencies in the systematic literature mapping and engaging indigenous and local people as co-researchers in documenting local knowledge. Furthermore, we propose a combination of internal and external review of our efforts to synthesise insight across the different knowledge spheres that are mapped within the different project parts.
