NBS objectives are also incorporated in the documents on strategy and additional spatial planning (Development...More
Restoring river-floodplains to protect biodiversity: The Danube’s river biodiversity is threatened by changes to hydrology and geomorphology (so-called hydro-morphological alterations), such as disconnection of floodplains. Multiple human activities, including the construction of hydropower plants, expansion of agriculture, and large-scale river regulation measures to increase navigation and flood protection are resulting in an ongoing loss of habitat and biodiversity. Our aim: In this Case Study, we apply the AQUACROSS Assessment Framework to identify how management of...More
Persina Nature Park has high conservation value but is also of importance to local economies through its fish resources, climate regulation and biomass production. However, the societal, economic and environmental value of this wetland is not well recognized by local and national stakeholders and decision-makers. This exemplar aims to explore the link between Danube ecosystems and a range of environmental benefits for local and Danube-region communities, given the application of an appropriate set of instruments to safeguard or improve them.More
Szeged’s urban development concept and integrated urban development strategy aim to improve the quality of green areas and to restore natural habitats and ecological corridors for social and recreational purposes and to mitigate the impacts of climate change. Due to the required structure for integrated urban development strategies and related financing mechanisms, there are separate objectives and plans for most urban districts (Liget, Mórapark, Makkosháza, Odessza, Roosevelt square, Tápé, Tarján, Stefánia, Vértó). They are called action areas and are developed in relation to the general...More
Urban redevelopment was an opportunity to adopt solutions and achieve different targets through nature-based solutions. Carta of Milan, the city's strategic environmental plan, recognises ‘green infrastructure’ as the best way to achieve environmental targets, promote social development and improve social welfare.

NBS could help address climate change, environmental infrastructure, green infrastructure, open spaces and recreation, cultural heritage and sustainable communities and neighbourhoods (1). For example, sustainable urban...More
„The river is a citywide public space.“
„Riverfront throughout the city are a coherent space, and their development, even in sub-sections, must always be addressed in a citywide context.“
The river and its banks are an essential city-forming element, and this is how the city should approach them. Until now, Prague lacked a concept for developing the vast potential of the river and its environments. The Prague Riverfront Concept, approved in 2014, rectifies this situation. Many of the most attractive riverside localities have been neglected, poorly managed...More
The objective of the LIFE-EnviFriendly project was to demonstrate low cost, nature based solutions that if used by all farmers within a watershed it will improve the water quality of the waters significantly.

Despite legal protection, mangroves were being cleared for shrimp farming by non-local investors. In a multi-day workshop, the ideas was to learn from local community stakeholders and participating scientists about the problems surrounding the conversion of mangrove ecosystems to shrimp aquaculture.
The aim was to develop potential solutions to the problems and communicate results to the authorities to take action. The main questions to be answered were: How to compare the value attached to shrimp farming with the value of maintaining mangroves? How can the economic, social and...More
Freshwater ecosystems in the Swiss plateau are threatened by multiple stressors that deteriorate water quality and hydromorphology. This is the result of channelization, dams, wastewater, and agriculture, among other causes. To restore these ecosystems and stop the biodiversity decline, multiple management measures will be implemented over the next decades. We propose methods for prioritising the location and timing of restoration measures to maximise their effectiveness, considering many sectors and multiple societal objectives.More
