DPSIR framework for eco-governance of transitional watersDefinitions and development of the DPSIR frameworkAlice Newton

~Definition of DPSIR~The development of the DPSIR

framework and its application to transitional and coastal waters, especially with respect to eutrophication

~Drivers and pressures associated with biomass production and extraction

What is DPSIR?~Drivers~Pressures~State~Impacts ~Responses

OECD (1993). OECD core set of indicators for environmental

performance reviews. OECD Environment Monographs No. 83. OECD. Paris.

The DPSIR framework links economics, social sciences and natural sciences

6

~Drivers: socio-economic activities, e.g. tourist development

~Pressures: that affect the environment and the ecosystem e.g. increase nutrient runoff

~State: quantifiable metrics, indicators of environmental and ecological quality e.g. Dissolved Oxygen, chlorophyll a concentration

~ 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

~Responses: of society to manage or abate the problem, e.g. new management criteria, new infrastructure, new policy

Transitional waters and lagoons play a key role in the Earth System functioning. They provide a significant contribution to the life support systems of most societies. Goods and services derived from coastal systems depend strongly on multiple trans-boundary interactions with the land, atmosphere, open ocean and sea bottom.Socio-economic drivers such as urbanization, food production, tourism and transportation accelerate the pressures on the coastal zone and resources.

Agricultural Drivers

Fertilizer use http://www.efma.org

~Industrial N- fixation and synthetic fertilizer process invented during WW1

~Not widely used ‘til 1950’s~Steady increase ‘til late 1980s~Slight decline to 1994

(collapse of Soviet collective farms)~Rapid increase since 1995

(China & India)

1996: annual fertilizer use ~83 Tg

26

Agricultural DriversMonoculture of

Legumes~Leguminous plants harbor symbiotic

micro-organisms in their root nodules~The micro-organisms can fix N2 and so

these plants can grow in N-poor soil~Beans, peas etc, protein rich crops ~Grown for human (soybean, peanut) and

animal consumption (clover, lucerne, alfalfa) as well as for biofuels (soybean, peanut)

Drivers: Biomass production

Animal Rearing~Netherlands: (2000)

~Human pop.= 15 700 000~Cattle = 4 200 000 4:1 ~Pigs = 14 000 000 1:0.9~Chickens 108 000 000 1:7

~Denmark (2004)~Human pop. 5 300 000 1:5~Pigs 25 000 000

…..5 times more pigs than humans…..15 times more pig manure than human sewage

Animal rearing

~Farm inputs (feeds,etc)~Output (meat & dairy)~Manure and what happens to it

Intensive pig farming

Waste production

1 pig=3 humans

36

37

The EU-12 pig farming is a growing sector that is shifting towards fewer holdings with larger numbers of animals. Evidence is also beginning to emerge of major investments in animal production units in Eastern Europe. Pig production units often import fodder from outside the EU, thus decoupling protein production from European farming.

Fisheries and Aquaculture

42

AquacultureDue to the increase of sea-food demand and the

decrease of natural marine stocks, coastal lagoons are increasingly exploited for aquaculture.

  Thau lagoon (France):• >10% French oyster production (~13000 tons) •Direct employment 2220• ~ 40 M€
