The concept of ecosystem services (ES) links ecosystem functioning and human welfare to achieve sustainable land use. However, the success of this concept will critically depend on sources to finance the provision of ES (possibly mobilized by means of markets for ES), on credibility of ES values and on willingness of ES providers to accept financial compensation. Our proposal addresses these aspects: The first part investigates how the land use in Ecuador would change if ES were actually acknowledged as economic values. We will use and develop a risk sensitive economic modeling approach to integrate the uncertainty of expected economic values for ES. The aim is to explore how the uncertainty of ES values would affect investments into specific ecosystem types and the connected conversion processes from tropical forest lands to other land use types and vice versa. The second proposal part investigates the willingness to accept financial compensation for providing ES. In this part we adapt a risk-sensitive bioeconomic farm model that combines various productive but sustainable land management options to real farm situations. The farm level modeling builds upon the effects of risk compensation from diversified land use by means of a land use portfolio approach. It will be used to derive acceptable individual and thus effective conservation payments.

生态系统服务的概念将生态系统功能和人类福祉联系起来，以实现可持续的土地利用。然而，这一概念的成功将主要取决于提供环境服务的资金来源（可能通过环境服务市场筹集）、环境服务价值的可信度以及环境服务提供者接受经济补偿的意愿。我们的建议解决这些方面：第一部分调查如何在厄瓜多尔的土地利用将改变，如果ES实际上被承认为经济价值。我们将使用和开发一个风险敏感的经济建模方法，以整合预期经济价值的不确定性ES。目的是探讨ES值的不确定性将如何影响对特定生态系统类型的投资，以及从热带林地到其他土地利用类型的相关转换过程，反之亦然。第二部分研究了提供环境服务的经济补偿的意愿。在这一部分中，我们采用了一种风险敏感的生物经济农场模式，该模式将各种生产力但可持续的土地管理方案与真实的农场情况相结合。农场一级的建模建立在风险补偿的影响，从多样化的土地利用的土地利用组合的方法。它将被用来获得可接受的个人，从而有效的保护付款。
