Strategic EIA Flashcards
Strategic EIA (SEA)
formalised, systematise and comprehensive process of evaluating the envt impacts of POLICY PLAN OR PROGRAMME including the preparation of a written report of the findings of that evaluation and using the findings in publicity accountable decision making
Policies
governments objectives and preferred means of achieving them
Plan and programmes
set of related actives and expenditures which give effect to policies
moving towards SEA
nertherlands set yo statutory SEA system in 1987
New zealand authorities have required SEA since 1991
Uk via changed in policy also SEAs of the MoD strategic defence review and the DTIs proposals for future oil and gas production
European Union directive in 2001: implementation 21st July 2004
project EIA reacts
it cannon direct applications to appropriate locations or away from sensitive areas it merely aids the process of acceptance or rejection
project EIA fails to adress cumulative impacts of several
additive effects of several small projects (A+A+A=3A)
interactive (A+B=C) or synergistic effects of several projects (A+A>2A)
(sunlight +NOx+ hdrocradbons—> Smog_
thresholds - i.e. level of pollution a water course can tolerate
induced impacts- secondary infrastructure around airports to motorways
alternatives only receive limited attention at project tlevel
often considered as an add on (similar problems with mitigation measures)
timescales
project EIA is financially and temporally contrasted: advanced planning should be less so
public consultation
limited by time and money in project EIA more immediately accountable if carried out by government
project EIA vs Strategic EA
Project EIA largely reactive and constrained
strategic EA (SEA) is proactive and should be less constrained
Objectives of SEA
consider alternatives fully- early
consistency across policy sectors
cumulative secondary impacts
anticipate adverse impacts and prevent them
save time and money at project level- dealing in advance
intergrate principals such as sustainability into policies
Difficulties
decision making at PPP level is often made incrementally
compexitity:
- high level decisions lead to potentially huge numbers of lower tier decisions
- system boundaries: not always clear
lack of information about bother proposal and future envt conditions therefore hard to quantify impacts
political considerations
Temporal and spatial scales
is 10 year impact significant in a 100 year plan?
1000 acres impact significant in a 200000 acre projecT?
lack of established criteria for significance
data used often speculative: lack of information can lead to incorrect assumptions
Scale
temporal
- generational- decades?
- decisionsal- weeks, months, years
(both at mercy of data getting out of date, policy changed, resources or finance running out)
How big an area? Local authority County Region Country catchment/ sediment cell. landscape unit
UK experience
1980s policy reviews - ad hoc reviews of operational efficiency with a primary focus on costs
Policy appraisal and environment (1991)
aimed at central government
set out podecdues and techniques
heacy emphasis on coast/benefit approach
little requirement for public involvement
sectoral approach leads to lack of intergration
Planning policy guindace Note (1992)
linked local council development plans with the objective of SD
required local authorities to have regard for envy considerations
by 1996 180 appraisals of development plans had been carries out but quality of the appraisal was variable
