Sustainable Urbanisation in cities


This domain will initiate and sustain dialogue among the various stakeholders (private and public sector, architects, practitioners, policy maker), on nature-based solutions in the context of sustainable urbanization in cities and human well-being. The dialogue will address the available opportunities for existing and new NBS associated with materials, buildings and infrastructure in cities. The incorporation of NBS in building and at district level will also be explored. The generation of co-benefits through greening cities in relation with climate change adaptation and mitigation will be examined as well as the role of cultural heritage in renaturing cities and how to incorporate existing knowledge from historic buildings and districts in restoration with nature. The role and effectiveness of NBS in advancing sustainable and resilient infrastructure development and upgrade will be explored together with replication strategies for renovating cities with nature. Methods for robust monitoring of the performance and assessment of the impact of deployed NBS will be examined.

Stewardship of urban ecosystem services: understanding the value(s) of urban gardens in Barcelona

Submitted by Stavros Stagakis on June 20, 2018 - 11:04am
The notion and assessment of ecosystem services (ES) values is becoming an established part of the discourse regarding urban green space performance. Yet, underlying factors enabling ES values are still poorly understood. We assume the production of ES value crucial for environmental stewardship in cities, and aimed in this study to uncover their key enabling factors.

Air contaminants and litter fall decomposition in urban forest areas: The case of S�o Paulo - SP, Brazil

Submitted by Stavros Stagakis on June 20, 2018 - 11:03am
Background Urban forests are usually affected by several types of atmospheric contaminants and by abnormal variations in weather conditions, thus facilitating the biotic homogenization and modification of ecosystem processes, such as nutrient cycling. Peri-urban forests and even natural forests that surround metropolitan areas are also subject to anthropogenic effects generated by cities, which may compromise the dynamics of these ecosystems.

Key insights for the future of urban ecosystem services research

Submitted by Stavros Stagakis on June 20, 2018 - 11:01am
Understanding the dynamics of urban ecosystem services is a necessary requirement for adequate planning, management, and governance of urban green infrastructure. Through the three-year Urban Biodiversity and Ecosystem Services (URBES) research project, we conducted case study and comparative research on urban biodiversity and ecosystem services across seven cities in Europe and the United States.

Subjective perception of noise exposure in relation to urban green space availability

Submitted by Stavros Stagakis on June 20, 2018 - 11:00am
Noise pollution has been recognized as one of major threats to the health of urban residents. Increasing green space availability can create a natural buffer to the adverse effects of living in an urban environment. These positive effects of urban green space can be directly related to an objective reduction of noise levels and – indirectly – to the subjective perception of noise exposure.

The health benefits of nature-based solutions to urbanization challenges for children and the elderly – A systematic review

Submitted by Stavros Stagakis on June 20, 2018 - 10:59am
Urban green and blue spaces promote health by offering areas for physical activity, stress relief, and social interaction, which may be considered as cultural ecosystem services. They also provide a number of regulating ecosystem services that can be regarded as nature-based solutions to mitigate impacts from urbanization-induced challenges. Urban trees and other vegetation provide cooling through shade and evapotranspiration, which reduce the impact of the urban heat island on hot summer days. Urban vegetation may improve air quality by removing air pollutants.

Nature-based solutions to climate change mitigation and adaptation in urban areas: Perspectives on indicators, knowledge gaps, barriers, and opportunities for action

Submitted by Stavros Stagakis on June 20, 2018 - 10:58am
Nature-based solutions promoting green and blue urban areas have significant potential to decrease the vulnerability and enhance the resilience of cities in light of climatic change. They can thereby help to mitigate climate change-induced impacts and serve as proactive adaptation options for municipalities. We explore the various contexts in which nature-based solutions are relevant for climate mitigation and adaptation in urban areas, identify indicators for assessing the effectiveness of nature-based solutions and related knowledge gaps.

Hybrid system for the purification of street stormwater runoff supplying urban recreation reservoirs

Submitted by Stavros Stagakis on June 20, 2018 - 10:57am
A high percentage of urban areas are covered by impermeable surfaces which reduce infiltration and landscape retention of stormwater. Moreover, the pollution flushed from these areas, particularly after intensive rainfall, is often drained directly to rivers and reservoirs which, in many cases, also serve a recreational function in cities. Stormwater runoff contributes to degradation of aquatic ecosystems and their intensified eutrophication which, in growing seasons, results in toxic cyanobacterial blooms.

“Not in their front yard” The opportunities and challenges of introducing perennial urban meadows: A local authority stakeholder perspective

Submitted by Stavros Stagakis on June 20, 2018 - 10:56am
The growing evidence base for the benefits for people and wildlife of nature-based solutions to managing urban green infrastructure lacks research investigating land manager perspectives on their implementation. To address this gap, we explored UK local authority manager perceptions of the challenges and opportunities of introducing perennial urban meadows to prioritise biodiversity and aesthetics. This was co-produced as an experiment in urban greenspaces with Luton Parks Service and Bedford Borough Council 2013–15.

Identifying Five Different Perspectives on the Ecosystem Services Concept Using Q Methodology

Submitted by Stavros Stagakis on June 20, 2018 - 10:54am
The objective of this paper is to recognize and categorize the various ways that ecosystem services researchers perceive the concept and purpose of ecosystem services (ES). To do so, we employed the discourse analysis approach of Q methodology, where 33 researchers ranked 39 statements on ES derived from the literature.

Greening cities – To be socially inclusive? About the alleged paradox of society and ecology in cities

Submitted by Stavros Stagakis on June 20, 2018 - 10:53am
Greening cities, namely installing new parks, rooftop gardens or planting trees along the streets, undoubtedly contributes to an increase in wellbeing and enhances the attractiveness of open spaces in cities. At the same time, we observe an increasing use of greening strategies as ingredients of urban renewal, upgrading and urban revitalization as primarily market-driven endeavours targeting middle class and higher income groups sometimes at the expense of less privileged residents. This paper reflects on the current debate of the social effects of greening using selected examples.
