Urban natural environments as nature-based solutions for improved public health – A systematic review of reviews

Submitted by Stavros Stagakis on June 20, 2018 - 12:15pm

Increasing urbanisation, changing disease scenarios, and current predictions of climate change impacts require innovative strategies for providing healthy and sustainable cities, now and in the future. The recently coined concept, Nature-based solutions (NBS), is one such strategy referring to actions that are inspired by, supported by, or copied from nature, designed to address a range of environmental challenges.

When we cannot have it all: Ecosystem services trade-offs in the context of spatial planning

Submitted by Stavros Stagakis on June 20, 2018 - 12:14pm

Spatial planning has to deal with trade-offs between various stakeholders’ wishes and needs as part of planning and management of landscapes, natural resources and/or biodiversity. To make ecosystem services (ES) trade-off research more relevant for spatial planning, we propose an analytical framework, which puts stakeholders, their land-use/management choices, their impact on ES and responses at the centre. Based on 24 cases from around the world, we used this framing to analyse the appearance and diversity of real-world ES trade-offs.

Biomanipulation as a nature-based solution to reduce cyanobacterial blooms

Submitted by Stavros Stagakis on June 20, 2018 - 12:14pm

We considered the limnological literature for an overview of biomanipulation methods that were implemented to avoid or reduce cyanobacterial bloom development in ponds and lakes. For this purpose, we reviewed 48 publications representing 34 whole-lake and large-scale case studies of different biomanipulation approaches clearly mentioning the extent of a cyanobacteria bloom problem and the cyanobacteria taxa involved.

Resilient landscapes in Mediterranean urban areas: Understanding factors influencing forest trends

Submitted by Stavros Stagakis on June 20, 2018 - 12:13pm

Urban and peri-urban forests are recognized as basic elements for Nature-Based Solutions (NBS), as they preserve and may increase environmental quality in urbanized contexts. For this reason, the amount of forest land per inhabitant is a pivotal efficiency indicator to be considered in the sustainable governance, land management, planning and design of metropolitan areas. The present study illustrates a multivariate analysis of per-capita forest area (PFA) in mainland Attica, the urban region surrounding Athens, Greece.

Wetlands as large-scale nature-based solutions: Status and challenges for research, engineering and management

Submitted by Stavros Stagakis on June 20, 2018 - 12:12pm

Wetlands are often considered as nature-based solutions that can provide a multitude of services of great social, economic and environmental value to humankind. Changes in land-use, water-use and climate can all impact wetland functions and services. These changes occur at scales extending well beyond the local scale of an individual wetland. However, in practical applications, engineering and management decisions usually focus on individual wetland projects and local site conditions.

Spatio-temporal dynamics of regulating ecosystem services in Europe- The role of past and future land use change

Submitted by Stavros Stagakis on June 20, 2018 - 12:11pm

Land use is a main driver for changes in supply and demand of regulating ecosystem services (ES). Most current ES inventories are static and do not address dynamics of ES supply resulting from historic and future land use change. This paper analyzes the role of land use change for the supply of two regulating services, flood regulation and climate regulation, in the European Union (EU) for the period between 1900 and 2000 as well as for four plausible scenarios of future land use change up to 2040.

A new marine measure enhancing Zostera marina seed germination and seedling survival

Submitted by Stavros Stagakis on June 20, 2018 - 12:10pm

Seagrass global distribution has declined in the last decades due to many causes, and the implementation of recovery programmes as well as the development of new restoration techniques are needed. This work describes the development of an innovative restoration measure to enhance Zostera marina (eelgrass) seed germination and seedling survival in sediments inhabited by lugworms (Arenicola marina) and its validation in mesocosm experiments.

Living shorelines enhanced the resilience of saltmarshes to Hurricane Matthew (2016)

Submitted by Stavros Stagakis on June 20, 2018 - 12:10pm

Nature-based solutions, such as living shorelines, have the potential to restore critical ecosystems, enhance coastal sustainability, and increase resilience to natural disasters; however, their efficacy during storm events compared to traditional hardened shorelines is largely untested. This is a major impediment to their implementation and promotion to policy-makers and homeowners.

Dynamic root floating technique: An option to reduce electric power consumption in aquaponic systems

Submitted by Stavros Stagakis on June 20, 2018 - 11:30am

Aquaponics is an integrated system in which the water containing fish waste is used as a nutrient source for plant production in a closed recirculation system. In this study, tilapia (Oreochromis niloticus) and pak choi (Brassica chinensis) culture was tested using two techniques: 1) Root floating (RAFT), and 2) Dynamic root floating (DRFT). Water quality parameters, total ammonia nitrogen, nitrate nitrogen, nitrite nitrogen and phosphate were measured. At the end of the experiment, fish and plants were weighed and the required electric power consumption was calculated.

Grassland productivity and carbon sequestration in Mongolian grasslands: The underlying mechanisms and nomadic implications

Submitted by Stavros Stagakis on June 20, 2018 - 11:29am

Background Quantifying carbon (C) dioxide exchanges between ecosystems and the atmosphere and the underlying mechanism of biophysical regulations under similar environmental conditions is critical for an accurate understanding of C budgets and ecosystem functions. Methods For the first time, a cluster of four eddy covariance towers were set up to answer how C fluxes shift among four dominant ecosystems in Mongolia – meadow steppe (MDW), typical steppe (TPL), dry typical steppe (DRT) and shrubland (SHB) during two growing seasons (2014 and 2015).
