Protected areas (PAs) are a large and growing asset class with unique legal and social characteristics. This report sets out a new asset framework for PAs, that involves new typologies for assets, investments, value creation, value capture, and risk management. This new framework could help PAs to generate more value, attract new investment, and better manage the risks that could strand PA assets. The new asset framework also represents a heuristic tool that can help underpin the case for new investment in PAs. In the report, we apply the framework to case studies in Brazil and Tanzania, conduct a systematic meta-analysis of the literature on PA value creation, undertake a preliminary assessment of the state of investments into PAs, and review current and emerging risks facing PAs.
