The value of the world's ecosystem services and natural capital

TLDR
In this paper, the authors have estimated the current economic value of 17 ecosystem services for 16 biomes, based on published studies and a few original calculations, for the entire biosphere, the value (most of which is outside the market) is estimated to be in the range of US$16-54 trillion (10^(12)) per year, with an average of US $33 trillion per year.
Abstract
The services of ecological systems and the natural capital stocks that produce them are critical to the functioning of the Earth's life-support system. They contribute to human welfare, both directly and indirectly, and therefore represent part of the total economic value of the planet. We have estimated the current economic value of 17 ecosystem services for 16 biomes, based on published studies and a few original calculations. For the entire biosphere, the value (most of which is outside the market) is estimated to be in the range of US$16-54 trillion (10^(12)) per year, with an average of US$33 trillion per year. Because of the nature of the uncertainties, this must be considered a minimum estimate. Global gross national product total is around US$18 trillion per year.

Freshwater biodiversity: importance, threats, status and conservation challenges

TL;DR: This article explores the special features of freshwater habitats and the biodiversity they support that makes them especially vulnerable to human activities and advocates continuing attempts to check species loss but urges adoption of a compromise position of management for biodiversity conservation, ecosystem functioning and resilience, and human livelihoods.

A typology for the classification, description and valuation of ecosystem functions, goods and services

TL;DR: In this paper, a conceptual framework and typology for describing, classifying and valuing ecosystem functions, goods and services in a clear and consistent manner is presented. And a classification is given for the fullest possible range of 23 ecosystem functions.

Changes in the global value of ecosystem services

TL;DR: In this paper, the authors provided an updated estimate based on updated unit ecosystem service values and land use change estimates between 1997 and 2011, using the same methods as in the 1997 paper but with updated data, the estimate for the total global ecosystem services in 2011 is $125 trillion/yr (assuming updated unit values and changes to biome areas).

Economic growth and quality of life: a threshold hypothesis

TL;DR: The inverted U-shaped curves that presumably result from the observation that "as income goes up there is an increasing environmental degradation up to a point, after which environmental quality improves" seem to be merely anecdotes that don't make history.

Valuation and management of wetland ecosystems

TL;DR: In this article, a study of wetland values in coastal Louisiana was conducted, which employed both willingness-to-pay and energy analysis-based methodologies and were able to bracket a range of values within which they feel fairly confident the true value lies.
