The institute used the huge Ecobuild conference in London to collar the Department for Communities & Local Government minister on issues around landscape and sustainability and to launch a document saying green-space investment has never been more necessary.
"Despite a groundswell of interest in recent years, this needs to be matched with funding and a new approach to the landscape that enables green infrastructure to flourish," said Illman.
Six recommendations in the position statement include the need for local authorities to make green infrastructure a core requirement in policy documents.
It wants landowners to think more creatively on generating capital and revenue to ensure green space is well managed and maintained. Illman said the green infrastructure approach to land use is often more cost-effective, resilient and capable of meeting social, environment and economic demands.
"It is no longer acceptable to approach these challenges in an isolated way. We need all those responsible for the planning, development and management of our land to accept that a more dynamic and integrated approach is crucial." For details, see www.landscapeinstitute.org/gi.
