Selecting methods for ecosystem service assessment: A Decision Tree Approach
Ecosystem Services, 2017Co-Authors: Paula A. Harrison, David N. Barton, Kees Hendriks, Robert Dunford, Eszter Kelemen, Heli Saarikoski, Berta Martín-lópez, Lisa Norton, Mette Termansen, Erik Gómez-baggethunAbstract:A range of methods are available for assessing ecosystem services. Methods differ in their aims; from mapping and modelling the supply and demand of ecosystem services to appraising their economic and non-economic importance through valuation techniques. Comprehensive guidance for the selection of appropriate ecosystem service assessment methods that address the requirements of different Decision-making contexts is lacking. This paper tackles this gap using the experience from 27 case studies which applied different biophysical, socio-cultural and monetary valuation methods to operationalise the ecosystem service concept towards sustainable land, water and urban management. A survey of the reasons why the case study teams selected particular methods revealed that stakeholder-oriented reasons, such as stakeholder participation, inclusion of local knowledge and ease of communication, and Decision-oriented reasons, such as the purpose of the case study and the ecosystem services at stake, were key considerations in selecting a method. Pragmatic reasons such as available data, resources and expertise were also important factors. This information was used to develop a set of linked Decision Trees, which aim to provide guidance to researchers and practitioners in choosing ecosystem service assessment methods that are suitable for their context.

Ecosystem Services Assessment of Two Watersheds of Lancang River in Yunnan, China with a Decision Tree Approach
Ambio, 2009Co-Authors: Chongyun Wang, Peter Van Der Meer, Mingchun Peng, W. Douven, Rudi Hessel, Chenlin DangAbstract:In the Langcang (Upper-Mekong) watershed, degraded watershed ecosystems in upland areas threaten cultivation practices, water resources, and dam development downstream. Assessment of ecosystem services and the factors that threaten them is an important first step to support watershed management. This, however, requires detailed information that is often missing in mountainous regions. To overcome this, in this paper, we adopt a Decision Tree Approach to assess protection, biodiversity, and production services in two mountainous watersheds (Fengqing and Xiaojie) of the Lancang River Basin. Decision Tree rules were built on the basis of field surveys, available references, ecosystem maps derived from remote sensing, expert knowledge, basic topographic information, and community interviews. Decision Tree results showed that forest cover and agro-forestry practices contribute greatly to improved ecosystem functioning in the Fengqing Catchment compared to the Xiaojie Catchment. The results were consistent with field observations. The Decision Tree method proved to be a suitable and flexible tool for the rapid assessment of watershed ecosystem services, for highlighting those areas that need more in-depth research, and for guiding watershed and ecosystem management.

Decision Tree Approach to power systems security assessment
International Journal of Electrical Power & Energy Systems, 1993Co-Authors: Louis Wehenkel, Mania PavellaAbstract:Abstract An overview of the general Decision Tree Approach to power system security assessment is presented. The general Decision Tree methodology is outlined, modifications proposed in the context of transient stability assessment are embedded, and further refinements are considered. The Approach is then suitably tailored to handle other specifics of power systems security, relating to both preventive and emergency voltage control, in addition to transient stability. Trees are accordingly built in these various application domains, and their salient features are explored, assessed, compared. Among attractive aspects of the Trees, we mention their ability to uncover the intrinsic mechanism governing physical processes, and to provide a clear description in terms of tractable system parameters. Further, their dual, ‘attribute space’ representation is shown to have complementary possibilities for more refined analysis and, in addition, for sensitivity assessment and control. Overall, the Approach is characterized by its great flexibility with respect to Tree structure, types of physical parameters driving the phenomena, and classes of potential applications. To illustrate and support the developments, real-world examples are reported, relating to transient and voltage stability issues simulated on several power systems.
