Using investment in GI to reduce the risk of damage to investment and the economy
Image, productivity, learning, low risk generally
Next logical step – how much are functions worth? How important are they?Globally, we’re still a long way from perfecting valuation techniquesBut it’s better to use what we have, if it’s sufficiently robust, than wait for perfectionToolkit brings together exactly that, and seems to give believable answersMapping is needed to provide inputs

Pinch Points• A Pinch Point is a location where due to one or more issues (the pinches) opportunities for investment and sustainable development are reduced. The result is that either investment does not take place or that any investment made underperforms.• By 2030, there is the potential for some 250,000 new jobs to be created in the Atlantic Gateway area and around 140,000 of these jobs will be associated with Atlantic Gateway priority projects, involving £14 billion of new investment.

Finally!• Can we afford not to make better use of GI?• Grey/Green Infrastructure.• We have many of the tools needed to identify where and how GI can support the economy and increase resilience.• Good examples emerging of use of GI by developers.• What does a GI engineer do? – Is that a step too far?
