Towards Participatory Integrated Valuation and Modelling of Ecosystem Services under Land-use Change

The lack of consideration for ecosystem services (ES) values in current decision making is recognised as one of the main reasons leading to an intense competition and arguably unsustainable use of well-located available land. In this article, we present a framework for the Valuation Of Terrestrial Ecosystem Services (VOTES), aiming at structuring a methodology that is applicable for valuing ES in a given area through a set of indicators that are both meaningful for local actors and scientifically constructed. Examples from a case study area in central Belgium are used to illustrate the methodology: a stepwise procedure starting with the valuation of ES at present. The valuation of the social, biophysical and economic dimensions of ES is based on current land-use patterns. Subsequently, scenarios of land-use change are used to explore potential losses (and/or gains) of ES in the future of the study area. With the VOTES framework, we aim at (1) incorporating stakeholders’ inputs to widen the valuation process and increase trust in policy-oriented approach; (2) integrating valuation of ES with a sustainable development stance accounting for land-use change and (3) developing suggestions to policy-makers for integrating ES monitoring in policy developments.

CICES going Local : Ecosystem Services Classification Adapted for a Highly Populated Country

Abstract Multiple classification systems for ecosystem services (ES) make comparison and integration between studies and assessments very difficult. With the fast-growing number of ecosystem services assessment and valuation studies, there is a need to identify generally agreed definitions and to design a common base that will enable comparisons between ecosystem services assessments at different places. The recently developed Common International Classification for Ecosystem Services (CICES) is aiming to fill this gap. One advantage of the CICES approach is that it allows adjustment to local conditions. Through an iterative consultation round with Belgian experts from administrations, policy support units, and research centers CICES has been adapted to the needs of a highly populated country, where multifunctional land use is very common. The goal of CICES-Be is to introduce a common reference base for ecosystem services in Belgium, which is locally adapted and compatible with an international standard.

The Tyndall coastal simulator and interface

Coastal zones attract settlements, are ideal for a range of economic activities and accommodate important natural habitats that provide ecosystem services. All these coastal activities are vulnerable to climate and other changes unless appropriate management policies are implemented. Sea-level rise and intensified storms could increase the incidence of flooding and erosion, as well as degrade coastal ecosystems. Importantly, the coast is a linked system, and management responses for one area or sector may influence the impacts for other areas or sectors. Understanding coastal processes and taking account of climate and socio-economic futures helps to illustrate/reveal impending choices,and in developing responsive informed long-term coastal management policies. This paper describes research being carried out by the Tyndall Centre for Climate Change Research on their Coastal Simulator. The research includes the linkage of a range of modelling procedures to represent coastal management and climate and coastal processes, as well as the design of a GIS-based interface to make the intergrated results accessible. The prototype simulator provides regional impact assessments of climate and socio-economic futures under various management options in the coastal zones of Norfolk, Fast Anglia and shows that erosion and flood risk are strongly linked.

Land Use Dynamics and Coastal Management

Changes in climate risk are driven by a range of socio-economic factors, as well as the climatic drivers considered in Chaps. 2 and 3. Exploring how the built environment might change over time is an essential element for assessing changing risks. This chapter presents and discusses two algorithm-based approaches used in the Tyndall Coastal Simulator to analyse local changes in residential and other urban land uses.
