Restoring Degraded Ecosystems Using NbS

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 degraded ecosystems restoration. The dialogue will address the expanding resource needs for land within Europe and how to prioritize agriculture, forestry, energy, transport and industry. The role of combined efforts in this field as well as innovative techniques for restoring and reclaiming land, such as soil fertility restoration techniques. The benefits of restoring ecosystems using green infrastructure and the role of restoration in increasing resilience and adapting to climate change as well as contributing to human wellbeing. Methods for robust monitoring of the performance and assessment of the impact of deployed NBS will be examined.

The provision of ecosystem services in response to global change: Evidences and applications

Submitted by Stavros Stagakis on June 20, 2018 - 11:02am
As a consequence of the global increase in economic and societal prosperity, ecosystems and natural resources have been substantially exploited, degraded, or even destroyed in the last century. To prevent further deprivation of the quality of ecosystems, the ecosystem services concept has become a central issue in environmental studies. A growing number of environmental agencies and organizations worldwide are now embracing integrated approaches to plan and manage ecosystems, sharing a goal to maintain the long-term provision of ecosystem services for sustainability.

Assessment of the spatiotemporal effects of land use changes on runoff and nitrate loads in the Talar River

Submitted by Stavros Stagakis on June 20, 2018 - 11:00am
This research surveyed the effects of land use changes on flow nitrate pollution in the Talar River (northern Iran), using Landsat images of 1991 and 2013 and the Soil and Water Assessment Tool (SWAT). The results indicated that forest areas decreased by 14.9% and irrigated crops, dry land farming areas, range lands and residential areas increased by 46.8%, 31.1%, 4.7% and 17.5%, respectively.

Bioturbation effects on bioaccumulation of cadmium in the wetland plant Typha latifolia: A nature-based experiment

Submitted by Stavros Stagakis on June 20, 2018 - 10:55am
The development of efficient bioremediation techniques to reduce aquatic pollutant load in natural sediment is one of the current challenges in ecological engineering. A nature-based solution for metal bioremediation is proposed through a combination of bioturbation and phytoremediation processes in experimental indoor microcosms. The invertebrates Tubifex tubifex (Oligochaeta Tubificidae) was used as an active ecological engineer for bioturbation enhancement. The riparian plant species Typha latifolia was selected for its efficiency in phyto-accumulating pollutants from sediment.

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.

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.
