The general objective of WP4 is to explicitly link the effects of land use change on soil biodiversity and the corresponding ecosystem services.The general hypothesis is that in soils, the relationship between biodiversity and soil ecosystem services is primarily controlled by dynamics and interactions in the soil community food web and that land use change will fundamentally alter soil biodiversity and the functioning of soil ecosystems. The results of WP4 will determine whether threshold effects might occur in terms of loss of biodiversity and ecosystem services in such a way that in WP5 these alterations can be valued in terms of economic costs and benefits.
Task 4.1 Food web structure and functioning: the development of a theoretical framework to link soil biodiversity to soil ecosystem services
Task 4.2 Ecosystem stability: the development of a theoretical framework to evaluate the effects of land use change on soil biodiversity and concomitant ecosystem services
Task 4.3 Valuation of soil biodiversity: the development of a common ecological-economic framework to relate soil biodiversity, ecosystem services and economic costs and benefits in the context of land use change (see also Work package 5)
