Position Statement
• LI Policy Committee recommended
  topics
• GI seen very much as the province
  of the landscape profession
• Small working group
• Call for case studies and comments
  on text from all LI members
• Sub-group met to decide on case
  studies
• Edits to text
• Reviewed by Executive Committee
  and “critical friends”
• Launched (May 2009)
• Use (lobbying, consultation
  responses etc)
“Can I congratulate the Landscape Institute
on the position statement for Green
Infrastructure. With so many
simplifications and misunderstandings as
to what GI really offers, this statement is
clear, lacking waffle and usable.”


“My planning colleagues who are currently
preparing the Council’s GI SPD as part of
the Core Strategy think it looks excellent
and would like to use it as part of the
launch and publicity of the Borough's GI
policy”

Origin of the term GI
Ed McMahon
  “Green space is not an
  amenity, it’s a necessity.”
  This is the phrase that
  underpins his concept of green
  infrastructure.
  “We coined the term to
  reposition the idea for the
  public,” explaining that the
  idea itself is not a new one.
Definitions (1)
• Explosion of interest doesn’t
  equate to increased understanding
• GI is term that can mean different
  things to different people
• A number of definitions available
• Significant common ground within
  the available definitions:
   – GI involves natural and managed
     green areas in both urban and rural
     settings
   – GI is about the strategic connection of
     open green areas and
   – GI should provide multiple benefits for
     people (public benefit).

Definitions (2):
Milton Keynes
 “A planned network of multifunctional
 green-spaces and interconnecting
 links, which is designed, developed
 and managed to meet the
 environmental, social and economic
 needs of communities across the
 sub-region. It is set within, and
 contributes to a high quality natural
 and built environment and is required
 to enhance the quality of life for the
 present and future residents and
 visitors and to deliver liveability for
 sustainable communities.”*
 * Planning Sustainable Communities: A green infrastructure
 guide for Milton Keynes and the South Midlands
Definitions (3):
Natural England
  “Green Infrastructure (GI) is a
  strategically planned and delivered
  network of high quality green
  spaces and other environmental
  features. It should be designed and
  managed as a multifunctional
  resource capable of delivering a
  wide range of environmental and
  quality of life benefits for local
  communities. Green Infrastructure
  includes parks, open spaces,
  playing fields, woodlands,
  allotments and private gardens.”
  www.naturalengland.org.uk
Definitions (4):
Northwest Region
  “Green Infrastructure is the
  Region’s life support system
  – the network of natural
  environmental components
  and green and blue spaces
  that lies within and between
  the Northwest’s cities, towns
  and villages and which
  provides multiple social,
  economic and environmental
  benefits”
www.greeninfrastructurenw.co.uk
Definitions (5)
  “Green infrastructure is the
  physical environment within and
  between our cities, towns and
  villages. It is a network of multi-
  functional open spaces, including
  formal parks, gardens,
  woodlands, green corridors,
  waterways, street trees and open
  countryside. It comprises all
  environmental resources, and
  thus a green infrastructure
  approach also contributes towards
  sustainable resource
  management.”
www.greeninfrastucture.eu
European Landscape
Convention (ELC)
Article 1 of the ELC states:
   “ “Landscape” means an area, as
   perceived by people, whose character is
   the result of the action and interaction of
   natural and/or human factors. The term
   “landscape” is thus defined as a zone or
   area as perceived by local people or
   visitors, whose visual features and
   character are the result of the action of
   natural and/or cultural (that is, human)
   factors. This definition reflects the idea
   that landscapes evolve through time, as
   a result of being acted upon by natural
   forces and human beings. It also
   underlines that a landscape forms a
   whole, whose natural and cultural
   components are taken together, not
   separately.”

GI funding
CABE & Natural England:
• call on local and central government
  to set new priorities for funding high-
  quality GI, highlighting the imbalance
  between investment in green & grey
  infrastructures.
• say towns and cities could be
  transformed if GI receives a fraction
  of the public investment made in
  other areas.
• suggest the government’s green
  stimulus package for low carbon
  housing be extended to incorporate
  GI; as part of a wider move to target
  public expenditure on greening cities.
  GI funding (2)
  “A switch of public spending from
  grey to green infrastructure would
  trigger an environmental revolution.
  At a time when investment in grey
  infrastructure, such as the new road
  building and road improvement
  programmes, runs into billions,
  investment in green infrastructure
  remains tiny. We have to redesign
  our cities in response to the
  imperative of climate change, and
  this means investment in hundreds of
  thousands of green roofs, millions
  more street trees, more parks, and
  new urban greenways.”
Richard Simmons, CABE’s chief executive

 Strategic Scale
GI Strategies
      • Need to operate at
      the relevant scale / level
      • Sub-regional and
      regional
      • Embed across a
      range of policies /
      strategies
      • Robust and flexible
      enough to react to
      political change - Tories
      committed to remove
      the English RDAs and
      wider “bonfire of the
      quangos”
Thames Gateway
South Essex Grid
Thurrock’s Green Grid Strategy
• TGGS developed in the context of the wider South
  Essex Green Grid (SEGG)
• Used its own technical research (biodiversity, green
  infrastructure, landscape and urban capacity, flood risk,
  green belt review and open space) to tackle overarching
  themes and principles laid out in SEGG and other
  strategic plans (the Greening the Gateway plan, Thames
  Gateway interim plan and Essex county plans).
• TGGS provides a finer grain framework than SEGG and
  gives expression to the aspirations of a wide range of
  partners and Thurrock’s own communities via its
  community strategy.
• It will be developed into SPD.

 GI Strategy for Urban
 South Hampshire
• PUSH – Partnership for Urban South
  Hampshire identified GI as critical to support
  sub-region’s development
• Polycentric urban region – Portsmouth,
  Southampton, Fareham, Gosport, Eastleigh
  & other settlements
• 1 million existing population - new growth
  point – brownfield, urban infill & greenfield
  needed to deliver 80,000 new homes
• Undertook:
    –   an appreciation of the drivers for change
    – environmental quality and condition assessment
      (including landscape character)
    – Analysis of community attributes
    – Gap analysis of GI strategy with other initiatives
    – Vision and values with stakeholders
    – Threats and opportunities
Public Benefit
• Central to the research was the
  area’s social, environmental and
  economic characteristics
• Potential for GI to address the
  deficits and deliver benefits in
  relation to:
   – Enjoying and protecting the special
     qualities of the environment
   – Restoring/enhancing environments
     degraded, in decline or at risk
   – Community needs and aspirations
   – Economic prosperity
• Used GIS to bring together
  datasets and represent spatially
  the areas in need and the multiple
  benefits
PUSH: Public Benefit




   High numbers of old, young &
   unhealthy

   Moderate numbers of old, young &
   unhealthy
Community needs
• Needs are greatest near the
urban areas based on
deprivation, age, risk of adverse
environmental quality etc




• Potential for delivering
community needs is a more
diffuse picture – widespread
opportunity for GI to deliver
functions
PUSH: Functional Strategies
• Stakeholders identified “themes”
  reflecting priorities
• Key quality of life issues for the
  area led to 8 headline themes
• Each comprised a range of GI
  functions
• Led to development of functional
  strategies:
   –   Biodiversity;
   –   Coast and Water;
   –   Green Access and Movement;
   –   Parks for the Future;
   –   Working Landscapes;
   –   Landscape Culture and Heritage.

The Mersey Forest
• The North West GI Guide sets out
  a 5-stage process for green
  infrastructure planning:

   1. Partnership and priorities
   2. Data audit and green infrastructure
      resource mapping
   3. Functional assessment
   4. Needs assessment
   5. Intervention plan.
1. Partnership & priorities

   – Local Authority strategies (health,
     education, open space, regeneration..)
   – Regional Forestry Framework
   – Regional Spatial Strategy
   – Regional Climate Change Action Plan
   – Regional Economic Strategy.
• Gross Value Added (GVA)
   – Developing ways to assess Mersey
     Forest achievements against partners
     monitoring targets of outcomes and
     outputs.
2. Resource mapping: Types
 •   general amenity space
 •   outdoor sports facilities
 •   woodland
 •   water courses

3.& 4. GI Functions:
definition & need
•recreation – public
   –DEFINITION: area anyone can use
   without having to pay or get keys
   – GREATEST NEED: high population
   density (present & future), low population
   mobility, poor health, much leisure time
•water storage
   –DEFINITION: Stores flood waters.
   –GREATEST NEED: upstream of urban
   areas intersecting flood plains
•shading from sun
   –DEFINITION: Shading of people,
   buildings, and surfaces from solar radiation.
   –GREATEST NEED: high population
