The AR4 was the first IPCC report to explicitly discuss the value of IK and LK in adaptation and mitigation processes. AR5 recognised the importance of creating synergies across disciplines in the production of knowledge, acknowledging the importance of 'non-scientific' sources such as IK, which may not follow discipline conventions but nevertheless reflects the outcomes of learning across generations . This also explains the importance of including IK and LK and diverse stakeholder interests and values in local decision making processes . Such processes should be done in partnership with IK and LK knowledge holders and, when possible, be led by them . Recent IPCC reports have included distinct sections dedicated to IK and LK . The IPCC Special Report on Climate Change and Land  includes a section on 'Local and Indigenous knowledge for addressing land degradation'  and the IPCC Special Report on Ocean and Cryosphere  describes LK as 'what non- Indigenous communities, both rural and urban, use on a daily and lifelong basis,' a type of knowledge which is recognised as 'multi- generational, embedded in community practices and cultures, and adaptive to changing conditions' . The IPCC Special Report on Global Warming of 1.5℃ emphasised the high vulnerability of Indigenous Peoples to climate change. It stated that disadvantaged and vulnerable populations, including Indigenous Peoples and certain local communities, are at disproportionately higher risk of suffering adverse consequences with global warming of 1.5℃ and beyond . The report also assessed evidence in relation to the importance of including IK and LK in adaptation options, explaining their role in early warning systems and arguing that they are part of a range of approaches to catalyse wide-scale values and are consistent with adapting to and limiting global warming to 1.5℃ .
