Urban Forest Boundaries

Within, between and beyond the city


The European Forum on Urban Forestry (EFUF) celebrates its 20th anniversary in the metropolis of Barcelona. The congress is open to international researchers and professionals who are interested in reflecting on the urban forest fringe areas as spaces of opportunities that can be connected with and contribute to the territory.

Twenty-first century cities have transformed their way of thinking: they have abandoned the idea of a central city with peripheral areas to now view the metropolis as a territorial mosaic of spaces, corridors and flows; a biophysical matrix where green infrastructure structures the territory to the detriment of the role of large transport infrastructure, and where spaces at the edge, on the limit, stop being administrative lines and begin to be seen as strategic spaces for ecology, leisure and production.

Under the title: "Urban Forest Boundaries. Within, between and beyond the city” we raise the importance of urban and peri-urban forests in building a sustainable and healthy landscape. We address issues such as ecological connectivity, compatibility of ecosystem services, biodiversity and disturbances, and the social aspects of forest management and planning those fringe areas in collaboration with the new culture of leisure. For all the above, we invite you to participate in our Congress, so that together we can address the latent problems in the contact and interaction between two realities destined to coexist: the city and open spaces.

    Connectivity and ecological value

    The urban forest, especially the boundaries, can play a fundamental role in improving environmental conditions and in preserving biodiversity (regulation of erosion and hydrology, ecological connectivity, neo-ecosystems, etc.)

    Keywords: connectivity, biodiversity, new ecosystems, canopy, climate change, resilience.

    Social and economic values

    Urban forest has many different social and economic functions, ranging from the provision of population with opportunities for leisure, health and welfare, to the contribution to energy savings in heating and cooling. Due to its nearness to urban zones, forest boundaries are also strategic metropolitan spaces.

    Keywords: health, leisure, social inclusion, equity, circular economy, local economy, economic valuation of ecosystemic services, cultural landscape.

    Towards a comprehensive approach

    A global comprehension of the benefits and multiple uses of the urban forest is required. Urban planning, design and public management of the forest boundaries must integrate ecological and socio-economical perspective on its approaches.

    Keywords: nature based solutions, adaptive management, citizen participation.

    Communication challenges

    Communication plays a key role in decision making. Regarding urban forests, we should face the triple challenge of a highly changing ecological environment, a particular social perception of the agroforestry areas and a lack of technical references for the evaluation of environmental disturbances due to its proximity to urban spaces.

    Keywords: decision-making, communication strategies, governance, participatory practices, resilience.

Logistical Key Notes

Metròpolis Barcelona

Barcelona Metropolis is characterized by being a compact and polycentric territory, which we call "metròpolis of cities" . It is composed of a mosaic of urban and environmental spaces that co-evolve and interact with each other. The territorial extension is over 636km2 and the population higher than 3.2 million citizens and 52% of the land is mainly occupied by green infrastructure.

This green infrastructure has a great ennviromental and social wealth value, and it is made up of more than 60 different habitats where more than 5,300 species live, divided into different types of areas: rivers (Llobregat and Besós), natural Parks system (Collserola, Garraf and Serra de Marina), 32 km of metropolitan beaches, metropolitan Parks network, urban parks and other green spaces integrated in the city such as streets, squares, balconies or green roofstops.

A landscape formed by the coexistence of different ecosystems (environmental and urban) that create in their boundaries or edges, fringes, limits and spaces of transition with different characteristics that establish diferent relations between these two realities, the urban and the environmental one, so necessarily linked.
