Green infrastructure for urban climate adaptation: How do residents’ views on climate impacts and green infrastructure shape adaptation preferences?

Submitted by Stavros Stagakis on June 20, 2018 - 10:42am

Cities are particularly prone to the effects of climate change. One way for cities to adapt is by enhancing their green infrastructure (GI) to mitigate the impacts of heat waves and flooding. While alternative GI design options exist, there are many unknowns regarding public support for the various options.

Natural Assurance Scheme: A level playing field framework for Green-Grey infrastructure development

Submitted by Stavros Stagakis on June 20, 2018 - 10:41am

This paper proposes a conceptual framework to systematize the use of Nature-based solutions (NBS) by integrating their resilience potential into Natural Assurance Scheme (NAS), focusing on insurance value as corner stone for both awareness-raising and valuation. As such one of its core goal is to align research and pilot projects with infrastructure development constraints and priorities. Under NAS, the integrated contribution of natural infrastructure to Disaster Risk Reduction is valued in the context of an identified growing need for climate robust infrastructure.

Challenges for tree officers to enhance the provision of regulating ecosystem services from urban forests

Submitted by Stavros Stagakis on June 20, 2018 - 10:40am

Urbanisation and a changing climate are leading to more frequent and severe flood, heat and air pollution episodes in Britain's cities. Interest in nature-based solutions to these urban problems is growing, with urban forests potentially able to provide a range of regulating ecosystem services such as stormwater attenuation, heat amelioration and air purification.

Green, circular, bio economy: A comparative analysis of sustainability avenues

Submitted by Stavros Stagakis on June 20, 2018 - 10:39am

Despite their evidently different assumptions and operationalization strategies, the concepts of Circular Economy, Green Economy and Bioeconomy are joined by the common ideal to reconcile economic, environmental and social goals. The three concepts are currently mainstreamed in academia and policy making as key sustainability avenues, but a comparative analysis of such concepts is missing. The aim of this article is thus to comprehensively analyse the diversity within and between such concepts.

Production of moss-dominated biocrusts to enhance the stability and function of the margins of artificial water bodies

Submitted by Stavros Stagakis on June 20, 2018 - 10:37am

Margins of water reservoirs associated with dams can have high-frequency tides, promoting soil erosion and nutrient leaching. We propose the use of biocrusts for restoration and ecological engineering purposes, due to their poikilohydric character, to stabilize reservoir margins. We promoted biocrust growth under controlled conditions, testing two types of substrate: native sand and organic substrate. After 2 months, biocrusts grew on organic substrate covering almost all the area, but not on native sand.

Renaturing cities using a regionally-focused biodiversity-led multifunctional benefits approach to urban green infrastructure

Submitted by Stavros Stagakis on June 20, 2018 - 10:36am

If a ‘Renaturing of Cities’ strategy is to maximise the ecosystem service provision of urban green infrastructure (UGI), then detailed consideration of a habitat services, biodiversity-led approach and multifunctionality are necessary rather than relying on the assumed benefits of UGI per se. The paper presents preliminary data from three case studies, two in England and one in Germany, that explore how multifunctionality can be achieved, the stakeholders required, the usefulness of an experimental approach for demonstrating transformation, and how this can be fed back into policy.

Do green spaces affect the spatiotemporal changes of PM2.5 in Nanjing?

Submitted by Stavros Stagakis on June 20, 2018 - 9:52am

Introduction: Among the most dangerous pollutants is PM2.5, which can directly pass through human lungs and move into the blood system. The use of nature-based solutions, such as increased vegetation cover in an urban landscape, is one of the possible solutions for reducing PM2.5 concentration. Our study objective was to understand the importance of green spaces in pollution reduction.

A two-step strategy for developing cultivated pastures in China that offer the advantages of ecosystem services

Submitted by Stavros Stagakis on June 20, 2018 - 9:50am

Based on a site experiment on a typical steppe of Inner Mongolia, the short term effects on aboveground biomass, soil water content, soil organic carbon, and soil total nitrogen of four cultivated pastures (CPs) with different compositions of herbaceous species were examined and compared to those of adjacent, natural grassland (NG) enclosed simultaneously. All CPs produced significantly higher aboveground biomass than did the NG after two years of establishment, and the mixed culture of Agropyron cristatum (A. cristatum) and Medicago sativa (M.

The reduction of Chlorella vulgaris concentrations through UV-C radiation treatments: A nature-based solution (NBS)

Submitted by Stavros Stagakis on June 20, 2018 - 9:48am

Algal blooms have become a pressing issue in inland freshwater systems on local and global scales. A plausible approach to reducing algae without the use of chemical/biological agents is through the use of UV-C radiation from lamps potentially powered by in situ solar panels to eliminate algae. Yet, the quantitative scientific base has not been established. Our objective is to conduct a controlled experiment to quantify the effectiveness of UV-C radiation on the reduction of Chlorella vulgaris, a common algal species in the Great Lakes region.

“Sponge City” in China—A breakthrough of planning and flood risk management in the urban context

Submitted by Stavros Stagakis on June 20, 2018 - 9:46am

Surface water flooding is currently viewed as the most serious water-related issue in many of the China's large cities due to rapid urbanization, land-use change and the process of rapid socio-economic development. In 2014, the People's Republic of China established the concept of the ‘Sponge City’ which will be used to tackle urban surface-water flooding and related urban water management issues, such as purification of urban runoff, attenuation of peak run-off and water conservation.
