Manifesto of the Nature-based Solutions Italy Hub (NbS Italy Hub)

We, supporters of Nature-based Solutions (NbS) and a new vision of urban and territorial development, wholeheartedly participate in the establishment of the Nature-based Solutions Italy Hub (NbS Italy Hub). Our mission is to promote the conservation of natural areas and the restoration of degraded ecosystems through NbS capable of transforming Italian cities into urban environments integrated with nature and biodiversity, with the aim of promoting the well-being of humanity and the planet.

Definition of Nature-Based Solutions

The definition of NbS to which we refer is the one coined during the Fifth Session of the United Nations Environmental Assembly (UNEA-5.2) in March 2022 and is in line with that adopted by the European Commission. This definition, agreed upon at the multilateral level, recognizes the fundamental role of NbS in the global response to climate change and its social, economic, and environmental impacts. According to the resolution, NbS is described as: “actions aimed at protecting, conserving, restoring, sustainably using, and managing natural or modified terrestrial, freshwater, coastal, and marine ecosystems that effectively and adaptively address social, economic, and environmental challenges while simultaneously ensuring human well-being, ecosystem services, resilience, and biodiversity benefits.”

Objectives and Vision

The main objective is to implement Nature-based Solutions (NbS) in civil and administrative practices, permeating local and national legislation and identifying them as necessary to achieve a just and sustainable transformation of society, no longer delayable in the current climate scenarios. This need has also been emphasized in the Kunming-Montreal Agreement for Biodiversity Conservation (Kunming-Montreal GBC, 2022). The Hub will support the standardization process required to achieve this goal. The vision of the NbS Italy Hub is that this is achieved through cooperation between the research community, the private sector, local administrations, and the population, in a process of integration with a fourfold helix approach, with full participation of all components of society.

Founding Principles

Valuing the ecosystem services of NbS in human-altered terrestrial and marine areas: In our vision of the future, NbS become effective tools for achieving the Sustainable Development Goals (SDGs) at the local, national, and global levels. We promote the multiple benefits they offer, from improving environmental quality to increasing food security, ensuring an abundant supply of high-quality water, and conserving biodiversity, all the way to mitigating climate change and reducing air pollution. These benefits must be estimated using validated scientific methodologies so that the value of NbS is recognized at the socio-political and economic levels, nationally and internationally, and serves as a prerequisite for defining replicable models and effective management strategies.

The Power of Green Spaces

Integrated planning, design, management, and use of green spaces: We support a targeted and multidisciplinary approach to the planning, design, creation, management, maintenance, monitoring, and use of green spaces. As with major urban infrastructure, we believe that green spaces should be considered and managed systematically. The integration of urban and peri-urban forests, parks, tree-lined streets, private gardens, and public spaces, as well as water bodies, will create an urban ecosystem capable of promoting functional, resilient, and continually evolving biodiversity in a more sustainable and harmonious manner.

Fostering Urban Wellbeing and Harmony

Green spaces as strategic landscape components: We consider green spaces as strategic components of the urban landscape, fostering harmonious relationships between cities and interconnected peri-urban and rural areas. Recognizing their ability to act as effective living systems that enhance human health and well-being and provide contexts for promoting new ecosystem dynamics, generating ecological niches, and promoting the regeneration of natural and cultural resources. We also believe that green areas are contexts for community cohesion and strategic areas where environmental justice and the preservation of natural and cultural heritage are fundamental pillars of urban sustainability.

The European context and the Restoration Law

We strongly support the recently approved -July 2023- “Nature Restoration Law,” which aims to restore 20% of degraded ecosystems by 2030, recognizing their central role in promoting cities and human-altered environments with greater biodiversity through nature- based solutions. The Environmental Restoration Law is fully aligned with our mission, as it focuses on the recovery of all ecosystems, including urban ones, integrating nature as essential infrastructure in both urban and peri-urban and rural areas. We offer our full support for the emphasis placed by the Restoration Law on community engagement, environmental education, and the promotion of shared responsibility for the sustainable management of regenerated green spaces.

Preservation of the complexity and integrity of ecosystems

We place great importance on the careful management of green spaces to preserve the highest levels of complexity and integrity of ecosystems, along with their associated environmental resources that characterize cities and human-altered environments. We support the protection and restoration of urban forests and ecosystems, the enhancement of connections between rural, peri-urban, and urban areas through environmental, urban, and landscape planning and design, the creation of functional ecological connections, corridor areas, and biodiversity conservation and protection contexts. These actions are essential to ensure water resources, soil and air quality, and to limit urbanization and habitat alteration, which are major causes of species extinction.

Development of NbS Italy Hub

Through the establishment of NbS Italy Hub, we are firmly committed to conserving and restoring biodiversity and environmental resources according to European strategies, promoting urban regeneration and sustainable development, with a strong focus on the well-being of humanity and the environment. The actions mentioned aim at a future where human-inhabited spaces thrive in harmony with nature, emerging as examples of resilience, biodiversity, and community well-being. Through our collective efforts, we aim to lead the ecological transition of Italian cities into sustainable places, permeated by an increasing presence of the natural element, and to inspire an innovative concept of urban planning and sustainable development on an international level.
