Blue/Green Infrastructure
The SRI's research focuses on the conservation of nature-based systems and increasing understanding of the ecosystem values they can provide to our communities.
Key areas of focus
- Urban Blue/Green Infrastructure
- Peatland conservation and wise use
- Wetland agriculture
- Invertebrate conservation
Blue/Green Infrastructure
Human impact on natural systems is at an all-time high causing global declines in biodiversity and ecosystem health. With predicted increases in populations and urbanisation, this pressure will intensify. An increasingly urbanised world, combined with intensive agriculture, forestry and exploitation of rural landscapes, freshwater and coastal marine ecosystems, has led to numerous environmental impacts associated with the loss of biodiversity.
In order to reverse these trends, it is necessary to understand how these systems function, interdependencies between them, and develop conservation and management strategies in order to build resilience and ensure sustainability.
The recognition of the natural environment as green infrastructure able to support the biodiversity necessary to provide a range of ecosystem services is a key step within this process in terms of understanding and communicating this value.
The SRI carries out research under a range of themes associated with green infrastructure with the aim of supporting this process.
Areas of activity
Urban Blue/Green Infrastructure
We live in an increasingly urbanised world where more than half the population already live in urban areas. Built upon old models of high-density living and economic development, towns and cities suffer the loss of biodiversity and numerous environmental impacts including:
- Urban heat island effect - leading to problems with air quality, energy use and ambient temperatures
- Sustainable Urban Drainage Systems (SuDS) - large expanses of impervious surfaces - resulting in rapid rainwater run‐off and overloading of storm drains causing localised flooding
- Reduction in water quality and the quantity of water held in the soil
- Reduction in surface seepage to re‐charge groundwater aquifers
- Urban biodiversity in Development and Policy - tackling reduced possibilities for contact with nature that are resulting in a reduction in the health and well‐being of urban communities
The incorporation of green infrastructure into cities can help alleviate these problems and contribute to the provision of ecosystem services. UGI is a critical field of study for the future of healthy and resilient cities. SRI leads international research on the design, planning and monitoring of UGI and has been instigating a range of cutting edge initiatives to demonstrate the multifunctional benefits of nature-based solutions in challenging urban environments

Peatland Conservation
Peatland activities in the SRI range from cutting-edge research through to the provision of scientific support and guidance on peatland issues to NGOs, government agencies and inter-governmental bodies. The SRI has an unparalleled track record in these areas and has helped bring a once-neglected area of research firmly onto the agenda of governments and public agencies at national and international level. The Peatland Team has a close working relationship with the IUCN UK Peatland Programme, providing a range of scientific support materials for the programme as well as devising new approaches to peatland evaluation, recovery, monitoring and outreach. As such, the team regularly produces syntheses of current peatland research in the form of briefing notes as well as creating a set of 3D animations to explain key issues.
The Peatland Team devised the IUCN UK Peatland Programme’s ‘Eyes on the Bog’ citizen science programme, and also designed, constructed and helped to run the Peatland Pavilion at COP26 in partnership with the United Nations Global Peatlands Initiative, the first such pavilion at any inter-governmental treaty conference of parties. The team was also represented on the Defra-led Lowland Agricultural Peat Task Force, providing recommendations to Government about the future management of lowland peat soils – recommendations which the Secretary of State accepted in total.
The team is also a major partner in the Greenhouse Gas Reduction-Peat Project being run by the UK Centre for Ecology and Hydrology, looking at ways of optimising peatlands for carbon capture.

Wetland Agriculture
Wetland Agriculture is an emerging research area in the UK, focussing on the sustainable use of wet peatland soils for agricultural purposes. Potential crops may be used for growing media, medicine, biomass, building material textiles and even food. This is an important research theme as it encourages the restoration and wise use of our wetland habitats.

Invertebrate Conservation
Invertebrates really are the little things that run the world. Their conservation is vital for global sustainability and resilience to secure a future for ecosystem services such as pollination, waste recycling, freshwater cleaning, soil creation and enrichment, food provision and pest control. Indeed, it is no underestimation to state that if the invertebrates disappear, the world's ecosystems would collapse.
Often overlooked in planning and legislation, maligned in the media and misunderstood by the public, it is vital that invertebrates are protected and conserved through appropriate habitat management. SRI leads international research on the ecology of invertebrates and the habitat design and management requirements for their conservation.
