This article describes the project "Drought and Water Use Conflicts in Germany (WADKlim)" its approach and the context in Germany. The project provides a nationwide overview of current water availability and its future development under climate change conditions. It analyzes emerging conflicts of use and develops possible solution strategies. For example, a concept for regional water advisory councils to strengthen intersectoral coordination will be designed. In addition, the potential of water reuse for irrigation in urban areas will be investigated. The project is funded by the Federal Environment Agency (UBA).

According to a recent EEA report co-authored by Ecologic Institute, water stress has become a serious problem across Europe and climate change is likely to raise the challenge. The report "Water resources across Europe – confronting water stress: an updated assessment" calls for a shift from crisis management to risk management to prevent irreversible negative consequences for nature and society. The report emphasizes the need for greater water use efficiency and improved ecosystem resilience, as water resources become insufficient to meet the joint demand of humans and nature.

Forests and the ocean are vital for climate, biological diversity, and human communities, but they are degraded and their ecosystem services are seriously impaired, mainly because financial, economic and governance structures are misconfigured. The authors of this T20 policy brief propose that G20 help strengthen the REDD+ climate instrument for forests and extend it to Blue Carbon from coastal and marine ecosystems. Scaled up to cover the Earth's two largest, most diverse and most productive ecosystems, these two approaches can deliver significant economic and climate benefits. The T20 policy brief is available for download.

The devastating flash floods and forest fires in Europe in summer 2021 have highlighted the need for stronger linking disaster risk management with climate adaptation efforts. This report introduces the concept of Sustainable Adaptation Pathways that can act as guidance when planning and implementing integrated policies to foster adaptation measures in line with disaster risk reduction efforts and sustainable development.

A comparative study indicates that the collective memory of the 1872 storm is related to the background knowledge about floods, the damage extent, and the response to the storm. Flood marks and dikes help to remember the events. In general, coastal flood defence is to the largest degree implemented in the affected areas in Germany, followed by Denmark, and is almost absent in Sweden, corresponding to the extent of the collective memory of the 1872 storm. Within the affected countries, there is local variability of flood risk awareness associated with the collective memory of the storm.

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.

Recent and historic high-impact events have demonstrated significant flood risks to many coastal areas in Europe and across the globe. Understanding the behavior of humans in relation to risk management poses grand challenges for both natural and social sciences and humanities. The study analyzes the cultural aspects of coastal risk management and illustrates path-dependencies of concrete disaster risk reduction measures in relation to local contexts in European coastal regions in Northern and South Western Europe. Dr. Grit Martinez from Ecologic Institute co-authored the journal article.

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.
