1 Critique of the DPSIR framework Alice Newton IMAR- University of Algarve

2 DPSIR vocabulary ~Drivers ~Pressures ~State ~Impacts ~Responses OECD (1993). OECD core set of indicators for environmental performance reviews. OECD Environment Monographs No. 83. OECD. Paris. Advantage: ordinary words not jargon Disadvantage: frequently misused or substituted

3 DPSIR + eutrophication BOD DO Nutrients O.E.C.D. 1993, 2004 Pressures State variables Responses

4 DPSIR + eutrophication

5 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

6 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

7 Impacts Need to break these down and check on all to see if there is are impacts that are: Environmental Ecological Economic Social Health

8 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

9 Impacts ~Environmental ~Ecological ~Economic ~Social ~Health ~Poor water quality ~Loss of seagrass, ecosystem service nursery function ~Loss of fishing catch and revenues ~Loss of fishing jobs ~Contaminated shellfish

10 ECOLOGICAL IMPACT Biological Quality Elements ~Phytoplankton ~Other plants ~Benthos ~Fish Annex V of WFD and Intercalibration

11 STATE IMPACT (ECOLOGICAL) Supporting elements: Nutrient concentrations Si:N N:P Transparency Bottom water Oxygen BQE metrics Chlorophyll a Cell counts HAB Opportunist algae biomass Biodiversity of benthos AMBI Biological Quality Elements Phytoplankton Other plants Benthos Fish Annex V of WFD and Intercalibration

12 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 Annex V of WFD and Intercalibration 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

13 Responses of society, e.g. new management criteria, new infrastructure, new policy

14 Conclusions

15 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?
