Strengthening urban governance for inclusive and effective nature-based solutions McKenna Davis, Senior Fellow and Coordinator of Nature-based Solutions at the Ecologic Institute, discusses the importance of strengthening urban governance to enhance the uptake and inclusiveness of nature-based solutions. Urbanisation is dramatically reshaping global landscapes, impacting the climate, straining natural ecosystems, and driving biodiversity loss. Cities both contribute to habitat degradation and face increasing vulnerability to climate change, with disruptions to ecosystem services affecting human health, social cohesion, and urban resilience. At the same time, cities are uniquely positioned to implement transformative solutions.

The number of studies on submarine groundwater discharge (SGD) and the evidence of its significance in biogeochemical cycling and potential impacts on the chemical and ecological status of coastal waters is increasing globally. Here, we briefly present SGD studies from the Baltic Sea identified along the coastlines of Denmark, Finland, Germany, Poland, Sweden and Russia in the southwestern, southern and north–northeastern parts of the Baltic Sea. We introduce a digital SGD map viewer and information platform enabling easy overview and access to information on identified SGD sites in the coastal areas of the Baltic Sea. SGDs potentially transport critical pollutants from urban and agricultural areas on land to the marine environment. The pollutants include nutrients, dissolved organic and inorganic carbon, metals, pharmaceuticals, and other emerging contaminants, potentially harming marine ecosystems and biodiversity and possibly contributing to the poor chemical or ecological status of coastal waters, affecting human and environmental health. We focus on case studies from Finland, Germany, Poland and Denmark that include the results and interpretations from the applied geochemical, geophysical and geological methods, as well as bionic autonomous underwater vehicles (AUVs) for locating, investigating, modelling and visualizing SGD sites in 2D and 3D. The potential Pan-European or even global SGD information platform established within the European Geological Data Infrastructure (EGDI) enables the easy combination and comparison of map layers such as seabed sediment types and coastal habitats. The EGDI map viewer provides easy access to information from SGD studies and may serve as an entry point to relevant information on SGDs, including contents of pollutants, for the scientific community and policy-makers. The information potentially includes the results of model simulations, data from near real-time sensors at permanently installed monitoring stations and surveys in time and space conducted by AUVs. The presented digital SGD information platform is particularly pertinent to the UN Sustainable Development Goal (SDG) No. 14, which focuses on the conservation and sustainable use of oceans and marine resources.

This article presents a practical case of a co-creation process within the framework of the European project Digital Water City (DWC). DWC sought to address the context and challenges of water in Europe with a participatory approach of co-creation as an integral part of Communities of Practice. To situate the concepts within their theoretical framework, the different approximations of co-creation and Communities of Practice (CoPs) are examined. The article analyzes the ways in which they have been used and applied in DWC as well as the ways in which the project has managed to articulate them at different levels. It discusses what has been done so far, whether the objectives related to co-creation have been achieved, what its added value to the project was, and the possible obstacles and successes. In order to gather this information, five case studies are presented and illustrated with a questionnaire that was carried out with the cities, researchers and key innovators. Results show that DWC´s co-creation process succeeded in incorporating end-users’ needs into the development of the digital solutions created, giving them a constructive role in the value-creation process, and bringing together different stakeholders from public and private sectors as well as researchers. It was also highlighted that the process and its format need to be adapted to each specific context and a culture of co-creation needs first to be established. The co-creation process and the DWC CoPs also raise governance questions and create new partnerships.

Abstract The differentiation between developing and developed countries has been one of the central issues in the climate change legal regime from the beginning. Although there is a consensus among countries regarding the CBDR-RC as the basis for differentiation, the developing countries have always emphasized the first part of the principle, the responsibility of the developed countries based on equity, and in contrast, the developed countries have focused on the second part, the capability of countries to deal with climate change. Due to this contrast between approaches, the differentiation in the evolutionary process of the climate change regime has always been very volatile, from the UNFCCC to the Paris Agreement. The question arises as to what direction the differentiation has gone and what path it will take. This research shows that the movement toward specialization, pragmatism, and flexibility indicate differentiation is going towards strengthening, and the attempt to weaken or gradually eliminate it will most likely lead to the meaningless participation of developing countries and ultimately the ineffectiveness of the regime. To achieve equitable differentiation along with global participation in the future, two-stage differentiation can be applied. In the first step, the differentiation should be applied between developed and developing countries based on an equitable approach to changing responsibility, and in the second step, sub-differentiation should be applied between the developing countries themselves based on national economic-environmental circumstances such as capability and vulnerability. In this case, differentiation will be considered an opportunity and catalyst instead of a threat and an obstacle.

This introductory textbook with a global scope aims to train students of geography, sustainability, and urban and environmental studies to re-imagine and transform cities to meet climate, biodiversity, and sustainability challenges. A dedicated team of authors critically examine the relationships between nature and urban areas, sharing an inspiring account of how nature helps us re-think our cities and their futures. Prior to this textbook, literature for courses covering urban nature was written by and for practitioners, whereas this textbook is written by experienced course instructors specifically to be accessible to diverse students. The textbook is illustrated with numerous photos and figures which bring key topics, challenges, and opportunities to life. It contains focus boxes and case studies from every continent, offering students an international scope and multiple entry points into the field. Chapters conclude with thought-provoking follow-up questions and recommended reading. The authors provide an array of supplementary online resources.

In 2011, MoorFutures® were introduced as the first standard for generating credits from peatland rewetting. We developed methodologies to quantify ecosystem services before and after rewetting with a focus on greenhouse gas emissions, water quality, evaporative cooling and mire-typical biodiversity. Both standard and premium approaches to assess these services were developed, and tested in the rewetted polder Kieve (NE-Germany). The standard approaches are default tier 1 estimation procedures, which require little time and few, mainly vegetation data. Based on the Greenhouse gas Emission Site Type (GEST) approach, emissions decreased from 1,306 t CO2e in the baseline scenario to 532 t CO2e in the project scenario, whereas 5 years after rewetting they were assessed to be 543 t CO2e per year. Nitrate release assessed via Nitrogen Emission Site Types (NEST) was estimated to decrease from 1,088 kg N (baseline) to 359 kg N (project), and appeared to be 309 kg N per year 5 years after rewetting. The heat flux − determined with Evapotranspiration Energy Site Types (EEST) – decreased from 6,691 kW (baseline) to 1,926 kW (project), and was 2,250 kW per year 5 years after rewetting. Mire-specific biodiversity was estimated to increase from very low (baseline) to high (project), but was only low 5 years after rewetting. The premium approaches allow quantifying a particular ecosystem service with higher accuracy by measuring or modelling. The approaches presented here have been elaborated for North-Germany but can be adapted for other regions. We encourage scientists to use our research as a model for assessing peatland ecosystem services including biodiversity in other geographical regions. Using vegetation mapping and indicator values derived from meta-analyses is a cost-efficient and robust approach to inform payment for ecosystem services schemes and to support conservation planning at regional to global scales.

ABSTRACT This paper considers the role of public consultations in complex agri-environmental policy-making. Through a critical discourse analysis of submissions to the public consultation concerning the European Union’s Farm to Fork Strategy, we examine the role of public consultations as a democratic process and the extent to which their non-deliberative nature advances solutions to contentious and complex challenges. We explore different perspectives around the future of agricultural pesticide use and find evidence of polarised submissions. Those in favour of reducing pesticides tend to argue on the grounds of planetary and human health, emphasizing that alternatives already exist and resistance to change results from a lack of political will. Those arguing against setting further restrictions on pesticide use, focus on food security and the lack of viable alternatives. Taking inspiration from Arnstein’s (1969) [A ladder of citizen participation. Journal of the American Institute of Planners, 35(4), 216–224] ladder of participation and Fishkin’s (2011) [Making deliberative democracy practical. Chapter 4. In When the people speak: Deliberative democracy and public consultation (pp. 95–105] questions around what makes deliberative democracy practical, we argue that consultations are not merely ‘tokenistic’, but do appear to be inadequate where discourses are strongly polarised, as they are not sufficiently inclusive or thoughtful, using scientific findings only where these support pre-existing views. As such, we explore how other deliberative approaches may be more adequate for seeking legitimate solutions to complex challenges.
