Green Health in Scotland

This months blog comes from Dr Rebecca Wade. Senior Lecturer in Environmental Science at Abertay University. Rebecca talks about a new initiative around a Natural Health Service in Scotland:

The environment we live and work in has a fundamental impact on our health and wellbeing.  Natural environments within our landscapes, including those that are managed, farmed and urban are important components of ‘healthy places’ with a role in promoting, maintaining and restoring good health, and preventing poor health.

In Scotland we recognise that the natural environment and associated green infrastructure is an important and undervalued asset for improving societal wellbeing and public health. Improvements in public health can be gained by increasing physical activity through green exercise - outdoor recreation, volunteering, play and learning, gardening and active travel.  Wellbeing benefits can be gained through enhanced contact with good quality natural and green/blue spaces even without physical activity.

Our Natural Health Service (ONHS) action programme is a national initiative led by Scottish Natural Heritage (SNH), in partnership with a range of organisations from health, sport, transport, education and environment sectors. This programme is investigating how greater use of the outdoors can contribute to improving public health and tackling health inequalities. The project concept has been brewing for a while, it dates back to 2007 when SNH, Forestry Commission Scotland and NHS Health Scotland formed a Green Exercise Partnership to promote better health and quality of life for Scotland’s people by encouraging more physical activity outdoors and more contact with nature.

In 2018, four Local Green Health Partnerships were established in Dundee, Lanarkshire, North Ayrshire and Highland. These are the centre piece of the ONHS Action Programme. Each Partnership is co-ordinating cross-sectoral local action to promote nature as a resource for health and wellbeing. They are developing green health services which support people to engage with the natural environment and be more active more often outdoors in their communities. In Dundee the partnership is working with NHS Tayside to pilot ‘green prescriptions’. These are now offered by three GP surgeries in Dundee. This trial, launched in 2019, has been achieved by working across sectors, disciplines, and organisations. This ‘joined-up’ approach is essential if we want to gain multiple benefits for people and nature. By working together we can achieve benefits in relation to water management, biodiversity, pollution control, health, well-being, education and much more.

Energy conservation benefits of green roofs

May's blog come from Marili Sotiriou, a Masters student at the University of Edinburgh, who recently began a 4-month research project on the energy conservation benefits of green roofs:

As part of my MSc dissertation and with the help of my supervisors, Dr Jennifer Carfrae (SRUC) and Dr Lynette Robertson (MEARU, Glasgow School of Art; Nature Harmonics Research and Consultancy), I recently began a 4-month research project on the energy conservation benefits of green roofs, focusing on one of Edinburgh’s most prominent extensive green roofs at the Scottish Parliament. The overall objective is an assessment of the impact of the existing green roof on energy balance and building energy efficiency , and to assess potential gains of integrating solar panels.

Green roofs can provide us with many advantages over conventional ‘non-living’ roofs, including storm water retention, wildlife habitat, and energy conservation, however research in the Scottish context, which can be used to inform decision making and design, is sorely lacking. Further, an benefit which has only developed more recently is energy production through incorporating solar panels in combined ‘biosolar’ green roof systems. As photovoltaic (PV) panels shut down when temperatures get too high, the lower temperatures of green roofs compared to conventional roofs offer a preferable environment for solar energy production.  In addition, PV panels create microclimate conditions on the green roof (e.g. shade) which that can enhance biodiversity.

Aims and Objectives

Energy performance of the green roof will be determined from: (i) primary data collection (temperature and moisture content, insulation properties of the roof) using thermal camera, thermocouples, portable weather station, and (ii) secondary energy data provided by the Scottish Parliament (reducing the data to that particular part of the building that is under study).

A statistical analysis (multivariate) will be undertaken prior to determining the energy performance of the green roof, and finally, a simulation model will be set up, using EnergyPlus, a building energy simulation software that can calculate the energy consumption of a building (Hui and Chan, 2011).  A comparison of the energy performance of four different roof types can be established. The types of roofs under study using this model will be:

1)    Bare Roof

2)    Green Roof

3)    Roof with PV

4)    Integrated system

New water management for the Republic of Korea

The first blog of 2019 comes from SGIF member, and previous Chair, Dr Brian D'Arcy. Brian focuses on his recent trips to South Korea and the inspirational water management projects being undertaken there.

 

South Korea is justly world renowned as a ‘can-do country’ – or ‘can do and does’!  The Cheongecheon Stream restoration project deserves praise for turning around an impoverished district of Seoul, and creating a thriving district where waterside strolls are a feature of everyday lunch breaks, cool evenings, and early morning too.  As a social improvement it has been an undoubted success. One of the most amazing aspects of the Korean achievement is that the project featured in the election campaign for the new Mayor of Seoul; pledging to spend millions of dollars on an environmental improvement proved to be a vote winner and he won.

As an example of real, ecological, river restoration, it is somewhat flawed however.   Although the old stream culvert was replaced with an open channel, there was no attempt to drain its catchment to the watercourse.  Awareness of diffuse pollution risks for the small stream (the consulting engineer involved was subsequently a chair of the IWA Diffuse Pollution Specialist Group) was the reason why surface runoff from the surrounding area was drained into new twin surface water sewers, one either side of the stream channel.   Prof Sung-Ryung Ha explained to me back in 2009 that they had no space for surface water treatment facilities such as raingardens, so rather than risk creating an open channel stream polluted with oily runoff and sediment, perhaps sewage wrong connections too, the engineers decided to supply clean water by pumping from the Han River, to guarantee their expensive new amenity feature in the heart of the city centre would look attractive at all times.  [Something very similar was done at the Edinburgh Business park, but that also involved putting a hitherto open stream into a new culvert…]. More than a dozen fish species have nonetheless colonised the Cheogecheon and a more relaxed approach to colonisation by aquatic and waterside plants is enhancing wildlife interest there.

The Mayor subsequently became head of the South Korean Government and embarked on a far more ambitious project:  the Four Rivers Restoration Project.  That was even more narrowly engineering-focused and drew a lot of criticism.  The growing ecological movement in South Korea supported others in advocating a more joined up approach to managing the water environment in South Korea.

The Korean Government held a series of consultation meetings and workshops in response to that and other pressures, and I was happy to be invited to participate in their 6th and final one in September 2017, when they sought international perspectives.   At the time, responsibility for water management was divided between two ministries: water quality management by the Ministry of Environment, and water quantity management by the Ministry of Land, Infrastructure and Transport. 

The outcome has been to make 3 key changes to the environmental legislation in South Korea[1]:

  1. The Government Organisation Act

This Act was revised and enacted on June 8th 2018, transferring Ministerial affairs on managing water quantity from the Ministry of Land, Infrastructure and transport (MOLIT) to the Ministry of Environment (MOE).

  1. The Framework Act on Water Management

This new framework Act establishes a master plan for national water management and for South Korea’s four major river basins, based on the concept of integrated water management.  It will be enacted in June 2019, establishing the national water management committee and basin committees, to promote sustainable and integrated water management.  The basin committees will provide a forum for concerns and dialogue.

  1. The Water Management Technology and Industry Act

Also a new Act, this legislation will be enacted in December 2018; it contributes to enhancing quality of life through the development of water management technology and promoting the water industry.

In the years since Cheongecheon, there has been additional encouragement of informal recreation in South Korea.  Other small tributaries are now also seen as attractive assets for informal recreation with streamside walkways, stepping stone crossings as well as footbridges, and seats and viewpoints.

These green corridors are now valued parts of the much-valued green infrastructure of the city, which includes stands of native pines and other trees, green walls and an impressive indoor green wall at the city hall.  Seoul also has a national park at the boundary of the city:  Bukhansan National Park, the most visited of the national parks in Korea.

Note

[Lest anyone in Scotland should be shaking their heads at the Cheongecheon development, it’s worth noting that the Edinburgh Business Park created a shorter but basically similar amenity feature, building a nice open watercourse with footpaths and seats, attractive waterside planting– but the city and developers put the local stream which was there prior to the development plans, into a new culvert!  The new Edinburgh ‘watercourse’ is fed by drinking water, with stormwater drained to the culverted burn… shocking but true].

SUDSnet 2018

In this blog Vladimir Krivtsov from the University of Nottingham shares his very positive impressions of the 2018 SUDSnet conference, which he had the pleasure to attend at the end of August 2018. It took place at Coventry University, and was dedicated to the celebration of 15 years of SUDSnet’s existence.

SUDSnet is a UK-wide network for researchers, practitioners, agencies, developers and all those who are interested in Sustainable Drainage Systems (SuDS)

Both days of the conference started with very interesting key note talks, and there was plenty of time for networking over the refreshment breaks, as well as during the conference dinner.

There were talks and posters covering a range of topics, including; logistics of operating SuDS infrastructure in challenging environments; water quality and pollution control; multiple benefits of SuDS in relation to biodiversity and wildlife habitats; the choice of plants and planters for source control assets; hydrological monitoring of SuDS performance; permeable filters and filter media; Natural Flood Management and Rural SuDS; education and raising awareness of SuDS, and; stakeholder engagement (see the conference programme for further details). The geographical coverage was impressively widespread (e.g. Iraq, South Africa, EU), and there was even a special session devoted to the international case studies.

Retrofit SuDS

A number of presentations discussed issues related to SuDS retrofits. For example, the logistics of retrofitting SuDS were discussed in the talks related to international case studies, including the challenging conditions of refugee camps. At a more local level there were presentations dealing with installations of SuDS on Scottish farms and industrial estates. According to the current legislation, all new developments in Scotland must have SuDS. The developers appear to be aware of that, but often go for installation of a limited number of features (e.g. permeable pavements in industrial estates; permeable pavements and/or swales and basins in housing estates) largely ignoring other possibilities.

It was reported that the majority of industry representatives have difficulties with terminology. Furthermore, about 75% of companies do not know about the General Binding Rules regulating pollution prevention and SuDS installation. There is a lot of confusion with understanding SuDS purpose, benefits and technology. There are also issues with maintenance, hence considerable scope for improvement! Figures 1 and 2 suggest some examples of specific SuDS features suitable for retrofitting into public roads and industrial premises respectively. These examples are from a study conducted by the Heriot-Watt team at Houston Industrial Estate (West Lothian, Scotland), but the results are expected to be applicable elsewhere in Britain and further afield.

Summary

All in all, the conference turned out to be very relevant to the Urban Flood Resilence project. I think that SUDSnet appears to be a very vibrant and worthwhile network. Their conferences take place every 3 years, and I will certainly be trying my best to attend the next one (alas subject to funding). The presentations from the recent one are due to appear online (keep checking SUDSnet 2018 presentations) – all great stuff, cannot recommend it more. I hope you will enjoy them as much as I did!

Scotland’s first raingarden officer appointed!

Scotland now has its first raingarden officer thanks to an innovative project from Central Scotland Green Network Trust and the Scottish Green Infrastructure Forum.

Europe’s largest greenspace initiative is hoping to follow successful projects in Melbourne, Philadelphia and Portland where raingardens have played an important role in dealing with surface water management, flood alleviation and greenspace creation. Funding has been secured from the Green Infrastructure Community Engagement Fund from SNH, the Peoples Postcode Lottery, Glasgow City Council and CSGNT.

Landscape architect, Rachel Howlett has taken up the new position and will be focusing on creating 10,000 raingardens for Scotland as part of the organisation’s focus on creating an environment that will support Central Scotland to thrive in a changing climate.

Rachel explained: “Scotland is known as a ‘wet country’ and raingardens can play an important role by using, storing or temporarily holding  rain water. This presents a fantastic opportunity to help reduce the impact of flooding whilst also contributing to improved biodiversity, pollution control and better greenspaces, and we have set the goal of creating 10,000 raingardens across l Scotland. ”

A Glasgow pilot project is now in place as the first phase of the national campaign to raise awareness and will focus on community and public engagement, developing raingarden plans and designs, and disseminating and promoting guidance on creating small scale raingardens.

The initiative will work with the Southside Housing Association and the community in Queensland Court and Gardens in North Cardonald, to produce bespoke, costed, raingarden designs. Queensland Gardens are two tower blocks owned by Southside Housing Association which are surrounded by short, regularly mown grassland, however there is currently no nature-based surface water management taking place.

Rachel, explained the plans for the area; commenting, she said: “Queensland Gardens presents an ideal opportunity to be innovative by creating multifunctional quality greenspaces which deal with pollution, water and biodiversity deficits. It is also important to use this initiative to provide play and education opportunities which can also contribute to a sense of mental wellbeing, pride and community empowerment.”

The 10,000 raingardens initiative is also focusing on raising awareness of the benefits of raingardens to encourage individuals, businesses and communities to create the systems in their gardens, community spaces and buildings.

As Europe’s largest greenspace initiative, CSGN is working to transform the central belt into a place where the environment adds value to the economy and where people’s lives are enriched by its quality.  Stretching from Ayrshire, Inverclyde and Dunbartonshire in the west, to Fife and Lothians in the east, it encompasses 19 local authorities across 10,000 sq km and has the potential to benefit 3.5 million people, equating to 70 per cent of Scotland’s population.
