Nature-based solutions: Lessons from around the world

Submitted by Stavros Stagakis on June 20, 2018 - 11:21am

This paper considers an emerging group of coastal management approaches that offer the potential to reduce coastal flood and erosion risks while also providing nature conservation, aesthetic and amenity benefits. These solutions mimic the characteristics of natural features, but are enhanced or created by man to provide specific services such as wave energy dissipation and erosion reduction. Such approaches can include beaches, dunes, saltmarshes, mangroves, sea grasses, coral and oyster reefs.

Nature-based agricultural solutions: Scaling perennial grains across Africa

Submitted by Stavros Stagakis on June 20, 2018 - 11:20am

Modern plant breeding tends to focus on maximizing yield, with one of the most ubiquitous implementations being shorter-duration crop varieties. It is indisputable that these breeding efforts have resulted in greater yields in ideal circumstances; however, many farmed locations across Africa suffer from one or more conditions that limit the efficacy of modern short-duration hybrids.

Nature-based solutions to promote human resilience and wellbeing in cities during increasingly hot summers

Submitted by Stavros Stagakis on June 20, 2018 - 11:20am

Air temperatures are increasing because of global climate change. A warming phenomenon strongly related to global climate change is the urban heat island. It has been shown that the hotter temperatures occurring in cities during the summer negatively affect human wellbeing, but little is known about the potential mechanisms underlying the relationships between hotter temperatures, cognitive psychological resources and wellbeing.

Integration of the ecosystem services concept in planning documents from six municipalities in southwestern Sweden

Submitted by Stavros Stagakis on June 20, 2018 - 11:17am

The ecosystem services (ES) concept refers to benefits that humanity receives from nature. Investigating how this concept has been embraced within urban planning is important when assessing the awareness of human dependence on natural functions and the potential for the ES concept to increase this awareness. We analyzed planning documents from three small and three large municipalities in southern Sweden to see how explicitly the ES concept was addressed and which individual services were mentioned.

Using local knowledge and sustainable transport to promote a greener city: The case of Bucharest, Romania

Submitted by Stavros Stagakis on June 20, 2018 - 11:17am

Cities undergoing climate change and rapid urbanization are faced with significant transformational processes that affect the environment and society, challenging them to become more sustainable and resilient. The promotion of nature-based solutions represents an efficient approach to meet sustainability targets in cities and improve the quality of life of citizens.

Melaleuca entrapping microsites as a nature based solution to coastal erosion: A pilot study in Kien Giang, Vietnam

Submitted by Stavros Stagakis on June 20, 2018 - 11:16am

Accumulation of fine grained sediment and natural regeneration of mangrove species are normally prioritized to control erosion on mangrove dominated muddy coasts. Current solutions to manage eroded mangrove dominated muddy coasts have been not as cost-effective as expected. Entrapping microsites, although mainly used for restoring eroded terrestrial resources, were first tested for restoring an eroded mangrove dominated muddy coast of Vam Ray, Hon Dat, Kien Giang, Vietnam.

The Value of Coastal Wetlands for Flood Damage Reduction in the Northeastern USA

Submitted by Stavros Stagakis on June 20, 2018 - 11:15am

As exposure to coastal hazards increases there is growing interest in nature-based solutions for risk reduction. This study uses high-resolution flood and loss models to quantify the impacts of coastal wetlands in the northeastern USA on (i) regional flood damages by Hurricane Sandy and (ii) local annual flood losses in Barnegat Bay in Ocean County, New Jersey. Using an extensive database of property exposure, the regional study shows that wetlands avoided $625 Million in direct flood damages during Hurricane Sandy.

Ecosystem services: Urban parks under a magnifying glass

Submitted by Stavros Stagakis on June 20, 2018 - 11:14am

Urban areas’ population has grown during the last century and it is expected that over 60% of the world population will live in cities by 2050. Urban parks provide several ecosystem services that are valuable to the well-being of city-dwellers and they are also considered a nature-based solution to tackle multiple environmental problems in cities. However, the type and amount of ecosystem services provided will vary with each park vegetation type, even within same the park.

A modelling framework for evaluation of the hydrological impacts of nature-based approaches to flood risk management, with application to in-channel interventions across a 29-km2 scale catchment in the United Kingdom

Submitted by Stavros Stagakis on June 20, 2018 - 11:14am

Nature-based approaches to flood risk management are increasing in popularity. Evidence for the effectiveness at the catchment scale of such spatially distributed upstream measures is inconclusive. However, it also remains an open question whether, under certain conditions, the individual impacts of a collection of flood mitigation interventions could combine to produce a detrimental effect on runoff response. A modelling framework is presented for evaluation of the impacts of hillslope and in-channel natural flood management interventions.

Prospects for improving gravity-fed surface irrigation systems in mediterranean european contexts

Submitted by Stavros Stagakis on June 20, 2018 - 11:13am

Traditionally, most irrigation practices in Southern Europe have been based on gravity-fed surface irrigation systems. Currently, these systems remain a relevant typology in the European Union (EU) member states of the Mediterranean areas, where it is often the only sustainable method for farmers due to the small size of agricultural holdings, their reduced capacity and readiness to invest and the low ratio between yield profits and irrigation costs.
