Novembers blog features the Urban GreenUP project, an EU Horizon 2020 with the objective of developing, trialing and replicating "Renaturing Urban Plans" in a number of European and non-European partner cities with the aim to mitigate the effects of climate change, improve air quality and water management, as well as to increase the sustainability of our cities through innovative nature-based solutions. This month, the project launched the results of their analysis on obstacles hampering the implementation of Nature-Based Solutions and possible related countermeasures:

Making our cities more sustainable and less harmful for the environment is one of humanity’s top priorities. Different approaches in this direction can be adopted. So far, renaturing urban plans by making use of Nature-Based solutions (NBS) are among the most effective ones. However, different kinds of barriers may stand in their way or slow them down. To top it all off, these hindrances are often times interlinked to one another which therefore makes it impossible for radical changes such as NBS to take place. To address this issue, the EU-funded URBAN GreenUP project has prepared a document identifying the main classes of barriers faced by its fellow cities. It also provides indicators on how to overcome such barriers, along with a collection of success and failure stories.

The document outlines different kinds of barriers. Some of these obstacles are purely technical and related to the NBS design and installation while others are of political, legislative, financial and social concerns, which may jeopardize altogether the implementation of these NBS.

In the realm of politics, one of the toughest barriers is the conflict and mismatch of priorities between local and the national governments. These include budget restrictions and cuts, as well as bureaucratic red tapes like land ownership.

Further complications arise by adding legislation into the picture. For one, legislative approval is required every time important changes such as NBS implementation is to take place in a city. This will become more troublesome if we also account for NBS’s unconventional designs that may violate the local legislative measures or protocols, and if these interventions should be implemented on private property.

Looking at it from a financial perspective, the biggest concern that the population may have is where the funding needed to implement NBS should come from. As a matter of fact, NBS most often fail to offer tangible cash return in the short term. This makes it less attractive for future investors.

Last but not the least, social barriers may arise as NBS impose a change of scenery and habits for the locals. For one, people have low public awareness as to how environmental protection can be beneficial to them. As a consequence, nature based interventions are considered among the citizens’ lowest priorities thus giving them a weak stance as to whether they should be supported.

The document is publicly available on the URBAN GreenUP website and is meant to provide guidelines and recommendations to cities and organisations implementing NBS.
