Key insights for the future of urban ecosystem services research

Understanding the dynamics of urban ecosystem services is a necessary requirement for adequate planning, management, and governance of urban green infrastructure. Through the three-year Urban Biodiversity and Ecosystem Services (URBES) research project, we conducted case study and comparative research on urban biodiversity and ecosystem services across seven cities in Europe and the United States. Reviewing > 50 peer-reviewed publications from the project, we present and discuss seven key insights that reflect cumulative findings from the project as well as the state-of-the-art knowledge in urban ecosystem services research. The insights from our review indicate that cross-sectoral, multiscale, interdisciplinary research is beginning to provide a solid scientific foundation for applying the ecosystem services framework in urban areas and land management. Our review offers a foundation for seeking novel, nature-based solutions to emerging urban challenges such as wicked environmental change issues.

Embedding CCS infrastructure into the European electricity system: A policy coordination problem

Carbon dioxide capture and storage (CCS) has recently been receiving increasing recognition in policy debates. Various aspects of possible regulatory frameworks for its implementation are beginning to be discussed in Europe. One of the issues associated with the wide use of CCS is that it requires the establishment of a carbon dioxide (CO2) transport network, which could result in the spatial restructuring of power generation and transmission systems. This poses a significant coordination problem necessitating public planning and regulation. This paper provides a survey over multiple research strands on CCS, particularly energy system modeling and spatial optimization, pertaining to the efficient installment of CCS-related infrastructure throughout Europe. It integrates existing findings and highlights the factors that determine policy coordination needs for a potential wide implementation of CCS in the next decades.

Der ökonomische Nutzen von Meeresschutzmaßnahmen – Erfassung und Bewertung im Rahmen der MSRL

Deutsche Entscheidungsträger sind bei der Umsetzung der EU Meeresstrategie-Rahmenrichtlinie (MSRL) mit ökonomischen Anforderungen konfrontiert. Vor dem Hintergrund des momentanen Wissensstandes ist deren Umsetzung in vollständig quantifizierter und monetarisierter Form nahezu unmöglich. Ein zumindest teilweise qualitativer Ansatz muss genutzt werden, für den eine entsprechende Handlungsanleitung vorgestellt wird. Der Forschungsund Handlungsbedarf wird beschrieben.

The Potential of Ocean Iron Fertilization as an Option for Mitigating Climate Change

Ocean iron fertilization is currently being discussed as one measure that could contribute to climate change mitigation by stimulating the growth of phytoplankton in certain parts of the ocean and enhancing oceanic CO2 uptake. Its implementation is greatly debated however and its mitigation potential has not yet been explored well. At present, it is still not possible to use carbon offsets generated through iron fertilization projects for complying with the Kyoto Protocol as trading these offsets is currently only possible on voluntary carbon markets. Company interests in such a commercial use of ocean iron fertilization do however already exist. Consequently, there is a need to explore the potential of ocean iron fertilization as a climate change mitigation option as well as regulatory issues connected with its implementation. This article combines these two aims by first examining the scientific background, quantitative potential, side effects and costs of ocean iron fertilization. In a second step, regulatory aspects such as its legal status and open access issues are reviewed. Moreover, the chapter analyses how the regulations for afforestation and reforestation activities within the framework of the Kyoto Clean Development Mechanism (CDM) could be applied to ocean iron fertilization. The main findings of this chapter are that the quantitative potential of ocean iron fertilization is limited, that potential adverse side effects are severe, and that its costs are higher than it was initially hoped. Moreover, the legal status of ocean iron fertilization is currently not well defined, open access might cause inefficiencies, and the CDM regulations could not be easily applied to ocean iron fertilization.
