Maximising Natural Capital Benefits for Brownfield and Sustainable Development

This webinar took place on 20 June 2024 11.00am

Duration: 2hr

We’re pleased to announce that the Maximising Natural Capital Benefits for Brownfield and Sustainable Development webinar has been rescheduled to take place on Thursday 20th June 2024 (11-1pm) at a cost of £30 inc VAT.  

Can development only be a threat to soil quality and natural habitats? How do we reconcile the competing needs of nature versus man? Too long we have underestimated the value and importance that the natural environment contributes to our well-being.

By taking a ‘natural capital’ approach to decision making, development can maximise eco goods and services whereby we can get more from our land. From the simple concept of delivering the ‘right land use in the right place’ to the more complex considerations of achieving and maintaining biodiversity or environmental net gain post-development.

This CPD webinar will explore how government seeks to support the reframing of nature in terms of the value to people and the economy to create sustainable development. Attendees will hear, through case study examples, about how organisations are already implementing this approach and the resulting benefits achieved.


BNG and ENG for Brownfield Sites

Tim Graham, Director at RSK Wilding and Nature Positive

Brownfield sites present a unique set of challenges and opportunities for BNG. In this talk Tim will discuss the inherent value of brownfield habitats for invertebrates and other biodiversity. The implications of contaminated land and its remediation, and the opportunities for BNG and other natural capital benefits (and income) from land often just seen as a long-term liability.

Vacant and Derelict Land (VDL) Re-use and Natural Capital

David Stewart, Policy and Practice Lead at Scottish Land Commission

David will be presenting on the work of the Scottish Land Commission on land use in general and re-use of VDL in particular. Looking at  previous work on VDL Re-use ,  forthcoming research, policy environment in Scotland, progress with land re-use since 2020 and highlights from Case Studies. This presentation will summarise and explore opportunities for VDL Re-use as greenspace/natural capital.

Remediation and Sustainable Growth Tool – Development of Natural Capital Metrics for Land Remediation

Yolande Macklin, Senior Associate Director, Land Quality, Jacobs and Dr Darren Beriro Principal Geoscientist, British Geological Survey

Yolande Macklin and Dr Darren Beriro will present on work undertaken for the Environment Agency on the development of a novel natural capital approach to evaluate the sustainability benefits from remediating and redeveloping contaminated brownfield sites. This proof-of- concept co-designed research is helping the Agency develop new methods to measure and communicate the social, economic and environmental value of  remediating contaminated sites, to optimise the planning, funding and delivery of its land contamination functions.

Maximising the Value of Brownfield Sites

Martina Girvan, Senior Technical Director at Arcadis

Martina will present case studies around maximising the natural capital value of brownfield land. In this interesting presentation she will discuss the BNG challenges and some of the solutions as well as innovative solutions to maximising natural capital benefits.
