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.

Reflections about blue ecosystem services in cities

Submitted by Stavros Stagakis on June 20, 2018 - 10:52am
Water is of particular importance for cities. Many fast growing megacities are facing serious water-related problems including pollution, eutrophication, missing wastewater treatment and, perhaps most importantly, a severe scarcity of clean water. In the entire urban world, water resources are used in an inefficient way. But there is great potential: this opinion paper discusses ecosystem services provided by waters-hereafter referred to as blue urban ecosystem services-and respective links to green infrastructure and the services they provide for human wellbeing.

Enhancing the Role of Geoconservation in Protected Area Management and Nature Conservation

Submitted by Stavros Stagakis on June 20, 2018 - 10:50am
Acknowledgement by the International Union for the Conservation of Nature (IUCN) that geodiversity is part of natural diversity and geoheritage is part of natural heritage should help to strengthen the position and delivery of geoconservation through engagement with the wider nature conservation agenda.

Linear parks along urban rivers: Perceptions of thermal comfort and climate change adaptation in Cyprus

Submitted by Stavros Stagakis on June 20, 2018 - 10:49am
The development of green space along urban rivers could mitigate urban heat island effects, enhance the physical and mental well-being of city dwellers, and improve flood resilience. A linear park has been recently created along the ephemeral Pedieos River in the urban area of Nicosia, Cyprus. Questionnaire surveys and micrometeorological measurements were conducted to explore people's perceptions and satisfaction regarding the services of the urban park. People's main reasons to visit the park were physical activity and exercise (67%), nature (13%), and cooling (4%).

Life Cycle Assessment of wastewater treatment systems for small communities: Activated sludge, constructed wetlands and high rate algal ponds

Submitted by Stavros Stagakis on June 20, 2018 - 10:48am
The aim of this study was to assess the environmental impact of three alternatives for wastewater treatment in small communities. To this end, a Life Cycle Assessment (LCA) was carried out comparing a conventional wastewater treatment plant (i.e. activated sludge system) with two nature-based technologies (i.e. hybrid constructed wetland and high rate algal pond systems). Moreover, an economic evaluation was also addressed. All systems served a population equivalent of 1500 p.e. The functional unit was 1 m3 of water.

Nature-Based Solutions in the EU: Innovating with nature to address social, economic and environmental challenges

Submitted by Stavros Stagakis on June 20, 2018 - 10:44am
Contemporary societies are facing a broad range of challenges, from pressures on human health and well-being to natural capital depletion, and the security of food, water and energy. These challenges are deeply intertwined with global processes, such as climate change and with local events such as natural disasters. The EU's research & innovation (R&I) policy is now seeking to address these challenges from a new perspective, with Nature-Based Solutions, and turn them into innovation opportunities that optimise the synergies between nature, society and the economy.

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.

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.

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.

Marine reserves can mitigate and promote adaptation to climate change

Submitted by Stavros Stagakis on June 19, 2018 - 6:43pm
Strong decreases in greenhouse gas emissions are required to meet the reduction trajectory resolved within the 2015 Paris Agreement. However, even these decreases will not avert serious stress and damage to life on Earth, and additional steps are needed to boost the resilience of ecosystems, safeguard their wildlife, and protect their capacity to supply vital goods and services.
