Abstract
AbstractLakes face threats from human activities like unsustainable development, population growth and industrial technologies. These challenges impact the ecosystem services of lakes. Research has assessed the monetary value of services from freshwater biomes annually. This article reviews these values, estimating lakes' global ecosystem services to be within the region of USD 1.3–5.1 trillion annually. Their natural asset value is estimated at USD 87–340 trillion, comparable to the monetary value of global real estate, assuming a relatively high social discount rate to account for future increased standards of living. Considering environmental degradation, future generations may experience a lower living standard. Using a 0.1% discount rate, recognizing potential harm and aligning with indigenous values raises the lakes' value to USD 1300–5100 trillion, which is at least equal to the global monetary value of wealth created. This valuation is shared by all as a collective asset, unlike the skewed distribution of created wealth.
