How Much Are Nature's Services Worth?

TL;DR: In a recent review of studies quantifying the costs and benefits of bird and insect activity in agroecosystems, a key challenge is to understand how plant–animal and animal–animal interactions provide ecosystem services on farms, in terms of increases in yield quality or quantity, or other production benefits.

TL;DR: In this paper, a decision support based on spatial analysis for the evaluation of payments for forest ecosystem services (PES) is presented, where the maximum willingness to pay by real estate owners and the minimum willingness to accept by forest owners are computed.

TL;DR: The synergistic effects resulting from the coupling of energy-related and natural stresses is very poorly understood as discussed by the authors, and the degree of imbalance is unnecessary, and without far greater emphasis on effects and more emphasis on human consequences and true cost to society of our energy systems will continue to go unnoticed.

TL;DR: In this article, the authors analyzed the data analyzed in this study indicates that 1970 revenues for motels and motor hotels kept pace with 1969 and transient and resort hotels experienced only nominal declines.

TL;DR: Helliwell as discussed by the authors proposed a system for comparing one wildlife resource with another; the whole system being correlated to monetary values at a later stage. But this method is regarded as being too tedious and difficult a process to be widely and frequently used.

TL;DR: In this article, a study of soil slippage on the San Dimas Experimental Forest in southern California after several large storms in 1965 and 1966 was performed. But the results showed that most slips occurred on slopes with slopes greater than 80%.

TL;DR: In this paper, the relative numbers, age-composition, and spatial distribution of coniferous trees in the San Bernardino National Forest were determined, and questions of importance to forest management were identified.
