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.

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.

Betting against Human Ingenuity: The Perils of the Economic Valuation of Nature's Services

Submitted by Stavros Stagakis on June 19, 2018 - 6:33pm
At the turn of the twentieth century, economic ornithologists focused on the monetary value of services provided by birds in order to fit nature conservation into the dominant economic paradigm. Pest control was of key interest because of its political importance and because it was relatively easy to quantify and monetize. However, this particular service became obsolete when a human-made solution was introduced that performed the same service - seemingly more cost effectively and reliably - undermining the political standing of economic ornithology.

The superior effect of nature based solutions in land management for enhancing ecosystem services

Submitted by Stavros Stagakis on June 19, 2018 - 6:25pm
The rehabilitation and restoration of land is a key strategy to recover services -goods and resources- ecosystems offer to the humankind. This paper reviews key examples to understand the superior effect of nature based solutions to enhance the sustainability of catchment systems by promoting desirable soil and landscape functions. The use of concepts such as connectivity and the theory of system thinking framework allowed to review coastal and river management as a guide to evaluate other strategies to achieve sustainability. In land management NBSs are not mainstream management.

Scanning agroforestry-based solutions for climate change mitigation and adaptation in Europe

Submitted by Stavros Stagakis on June 19, 2018 - 6:21pm
Agroforestry, the integration of trees and shrubs with livestock and/or crops, can make a substantial contribution to mitigating and enabling adaptation to climate change. However, its full potential will only be achieved if the challenges to agroforestry implementation are identified and the most efficient and sustainable solutions are made widely known. Therefore, the aim of this paper is to explore these challenges and to determine the most suitable set of solutions for each challenge that combines local effectiveness with European scale relevance.

Nature-based solutions: New influence for environmental management and research in Europe

Submitted by Stavros Stagakis on June 19, 2018 - 6:19pm
Greening roofs or walls to cool down city areas during summer, to capture storm water, to abate pollution, and to increase human well-being while enhancing biodiversity: nature-based solutions (NBS) refer to the sustainable management and use of nature for tackling societal challenges. Building on and complementing traditional biodiversity conservation and management strategies, NBS integrate science, policy, and practice and create biodiversity benefits in terms of diverse, well-managed ecosystems.
