Floodplain management in temperate regions : is multifunctionality enhancing biodiversity?

Background: Floodplains are among the most diverse, dynamic, productive and populated but also the most threatened ecosystems on Earth. Threats are mainly related to human activities that alter the landscape and disrupt fluvial processes to obtain benefits related to multiple ecosystem services (ESS). Floodplain management therefore requires close coordination among interest groups with competing claims and poses multi-dimensional challenges to policy-makers and project managers. The European Commission proposed in its recent Biodiversity Strategy to maintain and enhance European ecosystems and their services by establishing green infrastructure (GI). GI is assumed to provide multiple ecosystem functions and services including the conservation of biodiversity in the same spatial area. However, evidence for biodiversity benefits of multifunctional floodplain management is scattered and has not been synthesised. Methods/design: This protocol specifies the methods for conducting a systematic review to answer the following policy-relevant questions: a) what is the impact of floodplain management measures on biodiversity; b) how does the impact vary according to the level of multifunctionality of the measures; c) is there a difference in the biodiversity impact of floodplain management across taxa; d) what is the effect of the time since implementation on the impact of the most important measures; and e) are there any other factors that significantly modify the biodiversity impact of floodplain management measures? Within this systematic review we will assess multifunctionality in terms of ESS that are affected by an implemented intervention. Biodiversity indicators included in this systematic review will be related to the diversity, richness and abundance of species, other taxa or functional groups. We will consider if organisms are typical for and native to natural floodplain ecosystems. Specific inclusion criteria have been developed and the wide range of quality of primary literature will be evaluated with a tailor-made system for assessing susceptibility to bias and the reliability of the studies. The review is intended to bridge the science-policy interface and will provide a useful synthesis of knowledge for decision-makers at all governance levels

Judicial perspectives from the European Union for Public Participation in Environmental Matters in East Asia

This paper aims to provide judicial perspectives for Public Participation in Environmental Matters in East Asia based on the example of the European Union (EU). This is done both by means of an in-depth literature review which covers research papers, legislative documents and court decisions, and by means of a comparative analysis of court cases. The focus is on the implementation by the EU of the United Nations Economic Commission for Europe (UNECE) Aarhus Convention, which applies and details Principle 10 of the Rio Declaration. The assessment starts by providing an overview of several legislative documents issued by the EU for different policy sectors and briefly describes the contents regarding the implementation of the Aarhus Convention. Based thereon, the case law of the Court of Justice of the European Union is analysed. Seventeen judgements enforcing the Aarhus Convention for the EU level are described and their significance to a regional integration process is outlined. This provides valuable information to a region such as East Asia which plans to enter soon into a stronger regional integration process and which has the clear potential for improvement toward increased Public Participation in Environmental Matters based on the globally applicable Principle 10 of the Rio Declaration.SCOPUS: ar.jinfo:eu-repo/semantics/publishe

Sustainable development and invasive alien species : Implementation challenges of an EU regulation

Invasive alien species (IAS) constitute a trans- and intracontinental challenge. With this article, we exemplify obstacles met during the implementation of the Regulation (EU) No. 1143/2014 against IAS and comparatively assess them through two case studies from two Member States, Austria and Romania, via qualitative content analysis. Challenges are identified, analyzed, and discussed based on interviews with stakeholders from both countries in the view of the three main intervention types within this Regulation: prevention, early detection, and rapid eradication and management. The obstacles, which the two Member States met, are related to creating, updating, and maintaining the Union List and to the distribution of competences, which influence the national and subnational cooperation and coordination. Financial resources, custom controls, national legislation, and awareness influence the implementation of the IAS Regulation too. This research contributes to improving knowledge about numerous details of the implementation and enforcement of this IAS-Regulation to make them more feasible, not just for scientists, but also for decision- and policymakers, business owners, and other stakeholders.

From environmental soundness to sustainable development : Improving applicability of payment for ecosystem services scheme for diverting regional sustainability transition in developing countries

In developing and emerging countries, rapid urbanization at an unprecedented pace and degradation of ecosystem services at an alarming rate have caused many regions, especially those in environmentally sensitive areas (ESAs), to encounter the "regional development dilemma" (RDD), in which regions can hardly divert their current development pattern to achieve a transition to sustainability. The main research focus of this study is to introduce-by means of a case study-a payments for ecosystem service (PES) scheme as a policy instrument that incorporates an ecosystem services (ES)-based baseline for payments and a spatial-targeting-based allocation plan to address that dilemma and to bridge, as well as achieve, sustainable development goals simultaneously at a regional scale. The water source areas of the Middle Route Project in the South-to-North Water Diversion Project in China were used as the case study. Land Use/Land Cover Change (LUCC) of this area between 2002 and 2010 was detected by adopting remote sensing and spatial analysis technologies. The ecosystem services value (ESV) variation was then estimated and the eco-compensation plan was determined through comprehensively applying equivalent weighting factors of the ecosystem service of terrestrial ecosystems in China and the adjustment coefficient of the ecosystem service based on the notion of willingness to pay for ecosystem services. Results show that rapid urbanization has substantial impacts on the spatial dynamics and quality of ecosystems in the research area. From 2002 to 2010, the total ESV declined by CNY 6 billion. Therefore, the baseline eco-compensation from the benefit zone to the research area was CNY 1.1 billion under the assumption of commensurability. Responsibility ought to be shared by Henan and Hebei provinces, and Beijing and Tianjin, with payment of CNY 422.3, 388.5, 110.9, and 133 million, respectively. We drafted the allocation plan of eco-compensation based on the spatial pattern of ESV variation, and suggested policy tools tailored for subregions in the research area defined by LUCC change categories. Such an integrated study can lead to a more comprehensive understanding of regional PES schemes and provide a set of policy instruments with upgraded spatial-targeting and better cost-efficiency, particularly as blueprints for regional governments in developing and emerging countries that aim at leveraging regional sustainability through bridging and achieving SDGs

Multilevel coordination and cooperation during implementing supranational environmental legislation : A case study on invasive alien species

Coordination and cooperation are necessary topics to strengthen international environmental agreements that improve action against worldwide challenges towards sustainable development and environmental protection, such as invasive alien species (IAS). This study aims to assess to what extent national and transnational cooperation and coordination influences the implementation of a supranational regulation against IAS based on an example from the European Union (EU). Data is used from a broader study, including 47 responses to an online questionnaire and 22 interviews completed by experts from two countries (Austria and Romania), together with in depth literature. Additionally, the IAS-Regulation is analyzed from the perspective of cooperation and coordination. The terms "cooperation" and "coordination" were found within the text of the IAS-Regulation 11 and nine times respectively, whereas their context was transnational and national levels mainly, and transnational, respectively. It was further acknowledged from the majority of the answers from the survey respondents that the national coordination and cooperation is weaker than the transnational level due to the influence of the national competence distribution. Results from the interviews are separated into 'transnational' and 'national' cooperation and coordination. They show that the majority of the 47 responses indicate that the distribution of competence is one of the main influencing factors on the implementation. It is concluded that the current situation of cooperation and coordination in Austria and Romania renders it difficult for the European Commission to receive a realistic view about IAS and the implementation of the IAS Regulation in the two countries; hence, it is difficult to offer helpful support especially due to poor national cooperation. The current study can serve as a blueprint for further studies. Even in regional integration contexts beyond the EU, it can prove helpful to assess the impact of different kinds of competence distribution on the implementation of common norms. Thus, this research can path the way innovatively and serve as a comparative example for similar future studies
