If GI is the answer, what is the question?
?
“It’s not about the money, money: money!!”
“Its the economy stupid...”
But which bit of the economy? Are we credible?
• Growth• Unemployment• Inflation• Balance of payments
• Equal• Green “sustainable”

• Direct• Indirect• Reduce cost• Reduce risk
Do we have enough GI?
More GI than we think?
Liverpool • 64% GI
Liverpool City Region• 80% GI
“Britain's mental picture of its landscape is far removed from the reality”
“2.27% of England is built on.”

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.
Function Pinch Location of pinch points
accessible water storage
Risk of flooding Parts of areas of search with little accessible water storage upstream and a tendency to flood
aesthetic Risk of poor aesthetic
Parts of areas of search with little aesthetic (all will have strong need)
flow reduction through surface roughness
Risk of flooding Parts of areas of search with little flow reduction through surface roughness upstream and a tendency to flood
Darker areas indicate areas of greatest need for GI to address health issues
Dots indicate new projects funded by £300k from health sector

• Physical environments which promote good health may be important in the fight to reduce socio-economic health inequalities.”

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?
