【Necessary Conditions and Situational Variables of Payments for Ecosystem Services】

Ecosystem services (ES) are the fund-service resources that human beings acquire from the ecosystem. Changes in ES have serious impacts on human well-being. Payment for ecosystem services (PES) is an institutional arrangement that provides ES suppliers with positive financial incentives. PES schemes are attracting more and more attention from scholars and conservationists. This article proposes an analytical framework for the emergence of PES and argues that the key to determining whether PES can occur and whether a selected PES program is appropriate is to evaluate the net gain. And the cost and income composition of different types of PES are analyzed, and an investment model is used to describe them.

长久不衰的ABBA《Happy New Year. 》

No more champagne
No más champagne

The flare went out
La bengala se apagó

Only you, only me
Solo tú, sola yo

The celebration is over
El festejo ya pasó

It's the end of the party
Es el fin de la fiesta

And there is a gray dawn
Y hay un gris amanecer

Where is that yesterday
Donde está ese ayer

What should we propose
Que debemos proponer
Happiness, happiness
Felicidad, felicidad

By toasting we wish you from now on
Al brindar les deseamos de ahora en más

Peace, love where friendship reigns
Paz, amor en donde reine la amistad

Happiness, happiness
