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.

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.

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.

Five decades of soil erosion research in “terroir”. The State-of-the-Art

Submitted by Stavros Stagakis on June 19, 2018 - 6:46pm
Although soil erosion in vineyards is key to understanding the sustainability of agricultural management, there is not a worldwide definitive state-of-the-art review. It is accepted that soil erosion in vineyards has been more a scientific issue than an agronomic and environmental concern, and this review will point out key issues that will allow the designing of new and advanced research projects.

Overcoming water challenges through nature-based solutions

Submitted by Stavros Stagakis on June 19, 2018 - 6:39pm
Freshwater is a key resource and medium for various economic sectors and domestic purposes but its use is often at the expense of natural ecosystems. Water management must change to deal with urgent issues and protect aquatic ecosystems and their services, while addressing the demand for water from the competing claims for cities, agriculture, industry, energy and transport. In this paper key water challenges (shortage, pollution, aquatic ecosystems threatened) have been identified via global modelling.

How could companies engage in sustainable landscape management? An exploratory perspective

Submitted by Stavros Stagakis on June 19, 2018 - 6:39pm
Current concepts that aim to align economic development with sustainability, such as the circular and green economy, often consider natural systems as externalities. We extend the green economy concept by including the landscape as the provider of social, economic and environmental values. Our aim is to explore how companies could engage in creating landscape-inclusive solutions for sustainable landscapes. We propose a conceptual model of the relationship between companies and landscape services based on a demand for landscape benefits by companies, implications for wider society.

The Soil Value Exchange: Unlocking nature’s value via the market

Submitted by Stavros Stagakis on June 19, 2018 - 6:37pm
As the reality of a carbon-neutral market and future takes form, all available resources will need to be focused upon removing carbon dioxide from the atmosphere. In this regard, no alternative is more promising today than nature-based solutions. Restoration of native ecosystems and the use of management concepts such as adaptive multi-paddock (AMP) grazing for ranchland have the potential to reliably store vast amounts of carbon in near-surface soil at very low cost.

Drivers and trajectories of land cover change in East Africa: Human and environmental interactions from 6000 years ago to present

Submitted by Stavros Stagakis on June 19, 2018 - 6:36pm
East African landscapes today are the result of the cumulative effects of climate and land-use change over millennial timescales. In this review, we compile archaeological and palaeoenvironmental data from East Africa to document land-cover change, and environmental, subsistence and land-use transitions, over the past 6000 years. Throughout East Africa there have been a series of relatively rapid and high-magnitude environmental shifts characterised by changing hydrological budgets during the mid- to late Holocene.
