Abstract
The concept of green infrastructure has been recently taken up by the
European Commission for ensuring the provision of ecosystem services
(ESS). It aims at the supply of multiple ESS in a given landscape,
however, the effects of a full suite of management options on multiple
ESS and landscape multifunctionality have rarely been assessed. In this
paper we use European floodplain landscapes as example to develop an
expert based qualitative conceptual model for the assessment of impacts
of landscape scale interventions on multifunctionality. European
floodplain landscapes are particularly useful for such approach as they
originally provided a high variety and quantity of ESS that has declined
due to the strong human impact these landscapes have experienced. We
provide an overview of the effects of floodplain management options on
landscape multifunctionality by assessing the effects of 38 floodplain
management interventions on 21 relevant ESS, as well as on overall ESS
supply. We found that restoration and rehabilitation consistently
increased the multifunctionality of the landscape by enhancing supply of
provisioning, regulation/maintenance, and cultural services. In
contrast, conventional technical regulation measures and interventions
related to extraction, infrastructure and intensive land use cause
decrease in multifunctionality and negative effects for the supply of
all three aspects of ESS. The overview of the effects of interventions
shall provide guidance for decision makers at multiple governance
levels. The presented conceptual model could be effectively applied for
other landscapes that have potential for a supply of a high diversity of
ESS.
