This briefing note, published within the EU-funded Horizon 2020 project NATURVATION, takes a critical look at the value and limits of climate nature-based solutions to deliver on biodiversity goals. Building on research findings from NATURVATION, the brief discusses the question: How can we realise the added value of urban climate nature-based solutions for biodiversity?

There is a growing impetus among policy makers and practitioners to support and empower capacities of communities under changing climatic conditions. Despite this there is little systematic understanding of why approaches work at local levels or not and what makes some communities resilient and others less so. Authors addressing this shortcoming by providing illustrative case studies and assessment tools from Europe’s North, East and South helping to bridge the gap between climate change policies, decision-making and the cultural traits of communities in Europe.

Diffuse pollution is one of the key reasons European water bodies are failing to meet environmental objectives as specified in the EU Water Framework Directive (WFD). Outbreaks of toxic green algae affect rivers, lakes and coastal waters creating so-called "dead zones" where no aquatic life can thrive. Such outbreaks are by-products of dangerously increasing nutrient levels in water. Nutrient and soil losses have been recognised as challenges for decades across Europe and have been a key driver for freshwater biodiversity losses. With climate change, these challenges are likely to get worse: higher temperatures, lower river flows and more frequent and more violent flooding events. Other human-induced changes (such as dams and weirs) have modified the course of rivers and affected their natural flows.

Nature-based solutions (NBS) are emerging as a tool to integrate nature into territorial planning, with great opportunities to address these threats and benefit humans and ecosystems in parallel. The guide for integrating nature-based solutions in urban planning, a first approach for Colombia has been developed to facilitate the inclusion of nature in urban planning through a seven-step process. The guide was written by Carolina Figueroa during her time at Ecologic Institute as an Alexander von Humboldt International Climate Protection Fellow. The guide is available for download.

Nature-based solutions (NBS) are solutions that are inspired and supported by nature. They can be used in urban settings to complement or replace "traditional" or "grey" solutions to social and environmental challenges, such as air pollution, the heat island effect, water scarcity, flooding, loss of nature and lack of social cohesion. This guidance document highlights a range of policy and supporting instruments relevant for NBS design, implementation and maintenance.

This podcast explores different aspects of urban nature through stories of innovators from across Europe who use their passion and creativity to make cities green.

This study examines approaches of a set of European Union member states to pursue a coordinated approach to climate change adaptation (CCA) policy. It specifically addresses the co-ordination approaches that the selected countries use for the development and implementation of their national CCA policies in the immediate period following the publication of the EU's 2013 Adaptation Strategy.

Green roofs make buildings cool. Literally. As cities deal with the impacts of climate change, green roofs can offer solutions and help with rainwater management, insulation and cooling, amongst other benefits. No matter the weather, installing a green roof also benefits biodiversity and can transform inaccessible, unused areas into inspiring communal green spaces in the middle of densely built urban centres.

Local governments have little influence on short- and long-term climate policies taken at national and supranational levels. As the role of global cities is put to test by the Covid-19 pandemic, the need for an urgent and coherent management of the emergency in urban realities places further emphasis on the quest for sustainable urbanisation processes and strategies worldwide. Ewa Iwaszuk (Ecologic Institute) provides a commentary on the contribution of global cities to meeting the SDG13 within the ISPI Dossier "Global Cities in the Age of Covid-19: Agenda 2030 and Sustainable Development".

The multifunctional character of nature-based solutions enables them to provide responses to both social and environmental challenges. This policy brief provides gaps and opportunities to sustainable urban development through NBS at local and national as well as EU and international level. It also analyses local needs from the European and international levels.

This policy brief synthesises the latest results from the COACCH project on the economic costs of climate change in Europe and identifies areas of possible discussion to explore with stakeholders at the second COACCH workshop. The policy brief is available for download.

This report by Ecologic Institute explores the extent to which current policy frameworks support sustainable urban development and nature-based solutions (NBS). It reveals that a variety of different terms are used across countries in policies and discourses in support of sustainable urban development, with green (and blue) infrastructure being the most frequently used. However, while many policies were shown to have strong explicit support for sustainable urban development, these often lack mandatory policy instruments.

In this article, Dr. Grit Martinez ist concerned with the role of culture and history in relation to local knowledge and values, as these are displayed in the interpretations and actions of distinct groups regarding climate change. She argues that it makes sense to communicate the climate in a manner appropriate to the given cultural-historical context and imaginary and to the relevant semiotic and material views of the people in it.

The volume "Sites of Remembering: Landscapes, Lessons, Policies" of the Rachel Carson Centres' journal called "Perspectives" bridges the gap between humanities research and public policy. It uses a diverse selection of examples from worldwide memory studies to illuminate how society can employ lessons from the past in building resilience to ecological and humanitarian disasters. Dr. Grit Martinez of Ecologic Institute is a co-author. The volume is available for download.
