Abstract

fetched live from OpenAlex

Lakes 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 value of services from freshwater biomes annually. This article reviews these values, estimating lakes’ global ecosystem services to be within the region of USD 1.5 to 5.5 trillion annually. Their natural asset value is estimated at USD 100 - 337 trillion, comparable to value of global real estate, assuming a relatively high social discount rate to account for future increased standard of livings. 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 1,500 - 5,500 trillion which is at least equal to the global value of wealth created. This valuation is shared by all, unlike the skewed distribution of created wealth.

Fetched live from OpenAlex and de-inverted. Abstracts are not stored in this database: the inverted indexes are 8.6 GB of the frame’s 9.3 GB of text, and the host has 13 GB free.

Not calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels.

Machine scores (provisional)

The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.

Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
