A systematic review on high conservation value assessment (HCVs): Challenges and framework for future research on conservation strategy.

Various scholars and research institutions have attempted to assess High Conservation Values (HCVs) using different methodologies and approaches. Various countries have developed toolkits to determine High Conservation Value Areas (HCVAs) according to their needs and conservation strategies but there is no global agreement on them. The present study attempts to review research papers and assessment reports from 1999 until 2018 on approaches and methodologies used for HCVs all over the world and provide a review into HCV research systematically, with due consideration to the linkages between Biodiversity, Ecosystem Services and Socio-Economic-Cultural values.
