Title: Strategic Environmental Assessment


1
Strategic Environmental Assessment
  • Back to the Future
  • By Dr Anne F Kerr
  • 18 June 2005

2
Contents of Talk
  • SEA concept
  • Ingredients
  • Purpose
  • Communication of the findings and assessments
  • Case studies

3
Strategic Environmental Assessments
  • Suitable for Every Application ?

4
Essential Ingredients
  • Definition of robust baseline conditions
  • Identification of applicable assessment tools
  • Application of relevant key performance indicators

5
Purpose of an SEA
  • Essentially to identify impacts at a macro level
  • To allow rationale decisions to be made whether
    to take a project or development forward or not
  • To provide a powerful tool to communicate the
    implications of a development project or strategy
    in terms of the community at large and specific
    groups of sensitive receptors.

6
Example 1 SEA for the Relocation of the Airport
from Kai Tak
Chek Lap Kok Airport
Kai Tak Airport
  • Taking a step back into the future how was the
    site at Chek Lap Kok selected?

7
SEA for PADS - The Process
Coarse Screening
Fine Screening
Strategy Evaluation
100s of options and components
6 Options Environmental Modelling
including Air, Water Quality, Noise, Ecological
Assessment
3 Strategies Detailed Air Quality and Water
Quality Modelling
Environmental (and other) Assessment using
performance indicators
Environmental Assessment and testing against
performance indicators
Preferred Option
8
Processes Involved
  • Integration of the environmental planning aspects
    into the overall planning, land use, transport
    and engineering studies.
  • SEA was an integral component in the decision
    making process.
  • The option ultimately selected was optimal from
    an environmental perspective, which could be
    demonstrated through the findings and
    interpretation of the SEA.

9
Solution to All Problems?
  • Location at Chek Lap Kok increased journey time
    for many to and from the airport
  • Changed the location of the emissions from one
    airshed to another
  • Required major infrastructure to be constructed,
    New Towns, Highways, Lantau Link etc.

10
Environmental Components incorporated into the
Overall Development Plan
  • Natural coastline of Lantau retained by inclusion
    of Sea Channel in overall plan
  • Sea Channel also crucial to preservation of
    water quality in East Tung Chung Bay
  • Mangrove stands and ecological resources flourish
    in Pak Mong Lake through inclusion of Sea
    Bridges into the NLH design

11
Does the SEA model as applied to the Airport
apply to other cases?
12
HK2030
  • Ongoing study
  • 4 phased approach
  • Link to the website http//www.info.gov.hk/hk2030/
    hk2030content/home_eng/2030_e.htm

13
What are the desired outcomes for HK2030?
  • A development plan?
  • A list of proposed infrastructure requirements?
  • Is the outcome fixed or flexible?

14
HK2030 Scenarios
  • Must be flexible
  • Able to respond to change
  • Assist in the wider planning context taking
    account of the influences of the PRD

15
  • Need to provide a robust assessment of the
    implications in terms of air quality etc.
  • Not just comparison of results of modelling with
    the criteria
  • A real in-depth understanding of the implications
    of changes to assumptions upon which the
    scenarios are based

16
Back to the Future
  • Need to have robust modelling tools
  • Need also to interpret the data
  • Need to understand the implications of actions
    development, assumptions etc.
  • Need to be able to update the assessments given
    new developments, technology, targets for
    sustainability etc.

17
Back to the Future
  • Dont forget basic principles of interpreting
    data
  • Dont forget to play with the data and results to
    fully understand the implications not just
    pretty illustrations
  • Presentation is essential BUT needs to be totally
    supported by understanding.
