Résumé
Ecosystems provide numerous benefits to people, such as food, fresh water, fertile soils and recreation opportunities. These benefits are called ecosystem services. Land conversion and land use intensification degrade ecosystems and deplete ecosystem services. Such changes in land management also alter the composition of ecosystem services and maximize one or a limited set of services. For example, intensive agriculture maximizes crop production at the cost of water regulation, wildlife habitat, recreation and other services. This leads to ecosystem services trade-offs.

In this PhD research I developed a methodology to quantify the effect of land management on the spatial distribution of ecosystem services in order to determine ecosystem service trade-offs caused by land management. I developed GIS-based mapping and modelling tools to integrate information about the dependencies between land management and ecosystem service provision. The mapping and modelling tools were applied in combination with spatial analysis and scenario analysis. A wide range of ecosystem services were studied in three case studies, ranging from landscape to global levels : a small-scale Dutch landscape (the Groene Woud), the Baviaanskloof Catchment in South Africa and worldwide natural rangelands. The development of mapping and modelling methods was a core part of the research, as well as the demonstration of how these methods can be used to assess and evaluate land management effects on ecosystem services.
