This call, launched under the UPSURGE project, aimed to raise awareness and promote nature-based solutions in urban environments. When we announced it, we weren’t sure what kind of response to expect. Unlike previous programs—where residents received physical items like rain barrels or compost bins—this initiative invited participants to allow City Maintainer teams into their private gardens to construct functional raingardens, often requiring the use of machinery. It was a completely new approach.

To build trust and spread the word, Budapest engaged directly with residents at community events such as City Days and the Bikers’ Breakfast, and they organized a dedicated workshop for personal consultation and Q&A. Slowly but steadily, applications started to come in. In the end, we only had to turn down a few, simply due to unsuitable garden conditions.

Meanwhile, 25 public raingardens were also established across the city to serve as visible examples. Fortunately, the mild winter did not delay construction, and the rainy spring provided ideal growing conditions for the newly planted vegetation.

As the seasons progressed, we asked raingarden owners to share photos—and they’ve been doing so with pride. Many of the gardens planted in late autumn or early spring are now bursting with life. Initially dormant perennials, delayed by cool temperatures and night frosts, have since bloomed beautifully. The transformation has been striking, and the images speak for themselves.

In addition to the residential gardens, similar installations have also been created at district institutions, which can be visited during opening hours (in line with each institution’s visitor rules).

In fact, public raingardens are available for adoption—a great way for residents to contribute to the upkeep of these valuable green spaces.

A heartfelt thank you to everyone who participated and helped bring more greenery and climate resilience to Budapest’s neighborhoods. Let’s keep growing—together!

Held at the Friends of Field community garden, the workshop gave students the chance to connect with nature through fun and educational activities.

Students took part in a Bioblitz treasure hunt, where they explored the garden’s rich habitats, discovered insects, plants, and pollinators, and learned how even small green spaces can support urban wildlife. This hands-on activity helped spark curiosity about the natural world and highlighted the ongoing habitat enhancement efforts being carried out on-site through the UPSURGE project.

Students also got their hands dirty with seedball and seedstrip activities – learning how to grow their own wildflowers and vegetables and support pollinators right in their own communities.

One of the most hands-on and creative parts of the day was the planter-making session. With guidance from the amazing team at Belfast Tool Library, pupils rolled up their sleeves and built their very own wooden planters from recycled materials

Then came a burst of colour and creativity with a natural indigo dyeing workshop, led by Sue Bamford from Tools for Solidarity. Students watched as plain linen transformed into beautiful shades of blue using plant-based dye – a magical process that blended science, art, and heritage

The event was all about promoting sustainability, wellbeing, and hands-on learning, and we’re so grateful to everyone who made it possible.

Special thanks to the Green Fund from Sustainability at Queen’s University and the Belfast City Council Climate Team for their support.

On May 22, 2025 during the International Day of Biodiversity, Instytut Ekologii Terenów Uprzemysłowionych organised a meeting with the amazing students from Nasza Dobra Szkoła as part of the Katowice PlaceLab activities under UPSURGE project.

Special thanks to Prof. Edyta Sierka from the University of Silesia – expert of Katowice Competency Group, who gave an inspiring presentation on nature-based solutions (NBS) – with a special focus on green roofs, which are transforming urban landscapes worldwide.

The students dove deep into:

• The types, construction, and functions of green roofs
• Global examples of green infrastructure
• Hands-on activities including:
  • Building a model green roof in the schoolyard
  • Experiments on water retention
  • Analyzing soil mixtures
  • Exploring the importance of urban biodiversity

The enthusiasm, curiosity, and teamwork were truly inspiring. It’s clear that young minds are ready to build a greener future — one rooftop at a time!

A huge THANK YOU to the students, teachers, and parents for your incredible energy and support!

With the excessive use of Earth’s resources and rising pollution levels, human activity has begun to disrupt the natural balance to such an extent that nature can no longer regenerate itself in real time. This anthropogenic degradation of the environment must therefore be addressed through equally anthropogenic regenerative actions.

Inspired by the work of the Footprint Data Foundation (FoDaFo)¹, which maintains a system for calculating national ecological footprints and bio-capacity, the idea of developing a Regenerative Index was conceived. This Index encompasses seven indicative domains and is designed to reflect the degree to which an area supports environmental regeneration.

The Regenerative Index refers specifically to an anthropogenic regenerative index, representing a framework created by humans to assist nature in restoring balance in areas that have been heavily degraded. The Index rates an area’s regenerative status on a scale from 1 to 10. For example, a score of 3,4 indicates that the area is at 34% of the way toward achieving natural environmental balance.

The Regenerative Index assesses performance across the following seven interconnected domains (factors):

1. Air quality and corresponding pollutants
2. Spatial structure of the urban setting
3. Land properties and land designation
4. Regenerative governance approaches
5. Ecosystem services and biodiversity status
6. Participatory development and social impact
7. Gender sensitivity consideration

Each domain is evaluated independently, and a weighted average is used to determine the final Regenerative Index score. The Index is designed to reflect conditions over a full calendar year, ensuring seasonal factors are accounted for.

Figures 2–4 display the initial Regenerative Index scores for participating UPSURGE cities².

The UPSURGE cities’ Regenerative Index calculations form the basis for the development of Urban Insetting Protocols, which provide a framework for how cities can restore and balance their relationships with the ecosystems they depend upon.

The vision of Urban Insetting Protocols is to achieve the natural balance of the environment through regenerative urban (re)development in thematic areas aligned with the Regenerative Index’s seven assessment domains. Table 1 outlines the strategic and operational goals linked to each domain.

Table 1. Urban Insetting Protocols goals by thematic areas

The analysis of each city’s overall Regenerative Index score, along with the performance of each individual domain and their interrelations, informs the prioritisation of actions within the Urban Insetting Protocols. Based on the diagnostic outcomes, cities are encouraged to revise or develop strategic plans and implement targeted measures.

In the case of BP18, for example, recommended measures include the expansion of green areas (thus improving the Regenerative Index factor measuring spatial structure of the urban setting) and in particular long-term planting of shrubs and trees, critical for sequestering locally generated CO₂ (thus improving the Regenerative Index factor measuring regenerative governance approaches).

To monitor progress, annual Regenerative Index calculations are recommended. This helps assess the effectiveness of Urban Insetting Protocols and supports the ongoing refinement of actions based on achieved results.

Ultimately, the Regenerative Index serves both as a diagnostic and motivational tool, empowering cities to make evidence-based decisions and drive continuous improvement. Using the Regenerative Index as a monitoring tool can help bridge the gap between urban realities and strategic guidance, enabling cities to align their planning instruments with regenerative development principles. By measuring the territorial consequences of planning policies, the Index can be integrated into spatial planning practice as a central monitoring tool that strengthens the strategic capacity of spatial planning and supports its contribution to regenerative urban transformation. To increase its impact, the Regenerative Index should be actively promoted among and further developed with urban planners and policymakers to ensure its relevance and effectiveness.

Additionally, BP18’s calculations for the Factor of Participatory Development and Social Impact, as well as the Factor of Gender Sensitivity Consideration, need to be corrected. ︎

On April 8–9, 2025, all the Partners participated in the #UPSURGE Project Group Meeting in Budapest, Hungary, which was a good time to verify the achievements of all work packages and reflect on the expected project’s results. During the two-day meeting, all tasks and deliverables were discussed, showcasing what has already been achieved, while also identifying challenges and clarifying uncertainties. Partners actively engaged in discussions and took part in a workshop focused on the exchange of experiences from the Place Labs in five demonstration cities.

On the first day, all pillars of the European Regenerative Urban Lighthouse and the activities of the Urban Living Labs were thoroughly discussed. The current status of the implementation of nature-based solutions (NBS) in Belfast, Breda, Budapest, Katowice, and Maribor was also presented. Later, all participants took part in a site visit to observe the implementation of public and private rain gardens in Budapest’s 18th district.

The second day began with a discussion on project management and the status of tasks related to communication and dissemination of the project’s achievements and results. Other work packages were also analysed, including the use of measurement sensors, digitalization within the project, mobile applications, as well as various tools developed under the project that are intended to support the regenerative transformation of cities.

Several fruitful discussions and highly productive workshops moved the project activities and expectations forward. We are now more than sure how much more work is ahead of us, so full of energy we will face the final stage of our project. We would like to thank our Budapest Partners BURST and BP18 for your excellent organisation and extraordinary hospitality. It was a great pleasure for all of us to see by ourselves the effect of rain gardens’ implementation in a beautiful city space of Budapest.

Watch a short recap of the meeting on our YouTube channel:

Initial analysis of the greater survey conducted across six European cities gave interesting insight into different preferences across the continent. This study delves into deeper analysis of the survey responses from Greece. The survey methodology applied by BOKU – one of our UPSURGE partners – used a choice experiment to investigate what trade-offs residents are willing to make in order to have greener neighborhoods and reap the benefits of NbS. A latent class analysis among Greek residents illustrated how urban segregation causes unequal distribution of green areas and consequently also the exposure to climate change effects. Addressing aspects of environmental justice, participation and power this paper discusses different abilities and willingness to support NBS and recommends how green infrastructure and NbS can be implemented in order to grow environmental justice in our cities and provide access to NbS benefits to those who need it most.

The results of this study are important for planners and city administration as we consider not only the environmental benefits but also the social aspects NBS and greening our urban environments carries with it. The full publication is available open access and we invite you to take a look. We hope the results are food for thought and will spark conversations about the multiple benefits NBS bring to our cities and communities.
