Critique of the DPSIR framework

Alice Newton

IMAR- University of Algarve

dpsir vocabulary
DPSIR “vocabulary”

Advantage:

ordinary words

not jargon

Disadvantage:

frequently misused or

substituted

  • Drivers
  • Pressures
  • State
  • Impacts
  • Responses

OECD (1993).

OECD core set of indicators for environmental performance reviews. OECD Environment Monographs No. 83. OECD. Paris.

DPSIR + eutrophication

Drivers: need to update, maybe price of oil will be a major driver with increased biofuels

Pressures: need to consider “difficult” aspects such as loss of denitrifying wetlands, atmospheric deposition

examples of new drivers
Examples of “New” drivers
  • Tourism: car, plane, golf, demographics of coast
  • Lifestyles: joining EU!, changing economies central to market, changing diets, more meat
  • Agriculture (actually biomass production): biofuels, aquaculture
impacts need to break these down and check on all to see if there is are impacts that are

ImpactsNeed to break these down and check on all to see if there is are impacts that are:

impacts
Impacts
  • environmental e.g. increase turbidity,
  • ecological, e.g. loss of biodiversity,
  • economic e.g. lower fish catches,
  • social e.g. loss of fishing jobs
  • health e.g. contaminated shellfish

Poor water quality

Loss of seagrass, ecosystem service nursery function

Loss of fishing catch and revenues

Loss of fishing jobs

Contaminated shellfish

ecological economic impact impact
Phytoplankton

Increase HABs, NABs

Other plants

Loss of seagrass

Increase opportunistic algae

Benthos

Loss of sensitive taxa,

Increase tolerant taxa

Fish

Loss of nurseries for juveniles

Loss of sensitive taxa

ECOLOGICAL ECONOMICIMPACT IMPACT

Loss of aquaculture revenue

Loss of tourism revenue

Public health concerns ASP, DSP, NSP

Cost of removing algae

Mass mortalities

Loss of shellfisheries revenue

Fish kills

Loss of fisheries revenue

of society,

e.g. new management criteria, new infrastructure,

new policy

slide15
Drivers: need to update, maybe price of oil will be a major driver with increased biofuels

Pressures: need to consider “difficult” aspects such as loss of denitrifying wetlands, atmospheric deposition

State: need to test the metrics for the physico-chemical supporting quality elements and the Biological Quality Elements and move towards INTEGRATIVE ASSESSMENT

Impact: must link economic impact to ecological impacts, NOT consider them separately. Clearly shows the value of ecosystem services

Response: Should address the drivers! Is building UWWT plants the only answer? What about CAP and farming practices?
