Ancestral Domain and the Environment A very significant statistic that shows the critical role that the indigenous peoples play in the area of climate change and in the conservation of ecological integrity is the geographical distribution of Environmentally Critical Areas such as Key Biodiversity Areas (KBAs), Protected Areas and Important Bird Areas in the Philippines. Key Biodiversity Areas are defined by the International Union of Conservation Networks (IUCN) as areas that represent the most important sites for biodiversity conservation worldwide 100 (IUCN, 2011). Key biodiversity areas are places of international importance for the conservation of biodiversity through protected areas and other governance mechanisms (Ibid). Protected Areas (PAs), on the other hand, are areas of high environmental significance that have been reserved through executive edict or legislation, while Important Bird Areas (IBAs) are defined as areas recognized as being globally important  habitat  for the conservation of  bird populations. Currently there are about 10,000 IBAs worldwide and form part of a country’s existing protected area network, and are therefore protected under national legislation.  The ancestral domains of indigenous communities in the Philippines cover nearly 25% of the Asian NGO Coalition for Agrarian Reform and Rural Development (ANGOC)
