Does "greening" of neotropical cities considerably mitigate carbon dioxide emissions? The case of Medellin, Colombia

Submitted by Stavros Stagakis on June 20, 2018 - 11:24am

Cities throughout the world are advocating highly promoted tree plantings as a climate change mitigation measure. Assessing the carbon offsets associated with urban trees relative to other climate change policies is vital for sustainable development, planning, and solving environmental and socio-economic problems, but is difficult in developing countries. We estimated and assessed carbon dioxide (CO2) storage, sequestration, and emission offsets by public trees in the Medellin Metropolitan Area, Colombia, as a viable Nature-Based Solution for the Neotropics.

Nature-based solutions to promote human resilience and wellbeing in cities during increasingly hot summers

Submitted by Stavros Stagakis on June 20, 2018 - 11:20am

Air temperatures are increasing because of global climate change. A warming phenomenon strongly related to global climate change is the urban heat island. It has been shown that the hotter temperatures occurring in cities during the summer negatively affect human wellbeing, but little is known about the potential mechanisms underlying the relationships between hotter temperatures, cognitive psychological resources and wellbeing.

Using local knowledge and sustainable transport to promote a greener city: The case of Bucharest, Romania

Submitted by Stavros Stagakis on June 20, 2018 - 11:17am

Cities undergoing climate change and rapid urbanization are faced with significant transformational processes that affect the environment and society, challenging them to become more sustainable and resilient. The promotion of nature-based solutions represents an efficient approach to meet sustainability targets in cities and improve the quality of life of citizens.

Ecosystem services: Urban parks under a magnifying glass

Submitted by Stavros Stagakis on June 20, 2018 - 11:14am

Urban areas’ population has grown during the last century and it is expected that over 60% of the world population will live in cities by 2050. Urban parks provide several ecosystem services that are valuable to the well-being of city-dwellers and they are also considered a nature-based solution to tackle multiple environmental problems in cities. However, the type and amount of ecosystem services provided will vary with each park vegetation type, even within same the park.

Removal of PM10 by forests as a nature-based solution for air quality improvement in the Metropolitan city of rome

Submitted by Stavros Stagakis on June 20, 2018 - 11:12am

Nature-based solutions have been identified by the European Union as being critical for the enhancement of environmental qualities in cities, where urban and peri-urban forests play a key role in air quality amelioration through pollutant removal. A remote sensing and geographic information system (GIS) approach was applied to the Metropolitan City (MC) of Rome to assess the seasonal particulate matter (PM10) removal capacity of evergreen (broadleaves and conifers) and deciduous species.

Nature-Based Solutions for Europe's Sustainable Development

Submitted by Stavros Stagakis on June 20, 2018 - 11:10am

Pursuing economic targets of job creation, growth, and innovation while tackling global environmental challenges, has long been seen as impossible. However, any long-term economic competitiveness and security depends on the extent to which natural resources are used sustainably. Therefore, the European Union is investing in nature-based solutions to achieve this double goal. The difference between the prevailing economic model and a sustainable resource use has long seemed insurmountable.

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.

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.

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.
