8 SER still needed : SER established Our Mission: To promote ecological restoration as a means of sustaining the diversity of life on Earth and re-establishing an ecologically healthy relationship between nature and culture CBD 2010: spp/year (1/11 min)* Land conversion (population growth) * Up from in 2002 Bad economics: growth without limits -> destruction pays

9 natural hazards? Floods Storm damage Landslides > 1 trillion US$/year (NOAA, 2012)

10 Damage costs of natural disasters <- 1 trillion US$/y GDP 2012: 72 trillion US$ [INCLUDING the 1 trillion...]

11 Cost of ecosystem loss Water pollution cost Flooding cost 7.3 Trillion * US$/y. (2012) Lively- Hood loss Cost of ecosystem loss 2-5% of GDP per year (Science, 2002) (2-3 trillion $/y damage-costs, replacement & restoration costs, etc ) Air pollution cost * 13% of global GDP Crop loss (TEEB for Business Report, May 2013) 9 Oct 2010 Erosion cost

12 Cost of / INVESTMENT in Restoration? Needed: 100 billion $/year (Lester Brown, 2007) [less than 10% of the direct damage cost]

15 How to measure value (importance) Ecological value /importance (role in ecosystem) Intrinsic /existence value Cultural value (tradit. whaling, inspiration etc.)? Economic value Effect on welfare and the economy usually/conveniently expressed in monetary units. Whale: meat, tourism (DUV), biol. control (IUV), donations (NUV) Additional value (information) in decision making process [but very important/trade-offs]

16 How measure economic (monetary) value? 1. Market Price 2. Shadow Price (eco)tourism Coastal Protection Food 3. Questionnaire based Spiritual value /habitat service WTP for protecting Humpback Whales: 57 $/pp/year (1993) Replacement cost 10 million $/km Avoided damage Cost: 36 million $ (Maledives-2004). Other: Mitigation Cost, Travel cost, Hedonic pricing, Coastal Protection 4. Benefit (Value) Transfer

22 NATURA 2000 COST estimates Building on the results of the Member States questionnaire, the annual costs of implementing the Natura 2000 network were estimated as 5.8 billion per year for the EU-27. (Gantioler, 2010) Average: 63/ha/y (range: /ha/y) incl. acquisition & infrastructure dev. (30%) + management Marine sites: < 3 /ha/y.

23 Natura 2000 BENEFITS A number of examples have demonstrated that the benefits can be 3 7 times larger than the costs According to a study in Ireland, the aggregate benefits provided by the Burren park s limestone pavements and the orchid rich grasslands were estimated to amount to 4,420 / ha / year. The total benefit from the Park is estimated to be 65 million per year or about 3 times as much as the cost of Government support (Gantioler, 2010) The protection of all 300 Natura 2000 sites throughout Scotland was estimated to have an overall benefit cost ratio of around 7 over a 25-year period (Jacobs, 2004). Total benefits were estimated at 210 million per year, however, 99% is non-use value (Gantioler, 2010) In 2008 a study was carried out in France to determine costs and benefits of the Natura 2000 site Plaine de la Crau. The calculated overall net benefits amounted to 142ha/year, which was around seven times higher than the costs associated with the site. (Hernandez & Sainteny, 2008).

34 Why continues?

35 Conventional (outdated) economics Society must urgently replace its defective economic compass (Pavan Sukhdev, TEEB study leader, CBD COP9) some problems: - Free services (75%) [pollination] - Neglect of externalities [pollution] - Perverse subsidies [fishery, forestry] - Wrong assumptions (paradigms) about people & markets

36 EU Biodiversity Strategy 2020 (May 2011)* Subtitle: our life insurance, our natural capital Action 5: Improve knowledge of ecosystems and their services in the EU Target 2: by 2020, ecosystems and their services are maintained and enhanced by establishing green infrastructure and restoring at least 15% of degraded ecosystems All member states... will: (1) map and assess the state of ecosystems and their services in their national territory by 2014 (2) Assess the economic value of such services by 2020, and (3) promote the integration of these values into accounting and reporting Systems at EU and national level Ecosystem Services Partnership ESP *) CBD COP-10 Nagoya,

37 How turn value into real money? - Reward/Pay providers of free services - Punish environmental damage (liability) 1. Government run finance mechan. (public incentives: subsidies/taxes) - Agri-environmental schemes [ farming for nature ] - Conservation payments (e.g. watershed-prot. [NYC] / REDD+ (forest) - Other (eg. tax-incentives for green investments) 2. Government supported market creation - Offsets, eg Carbon credits [145 billion$ 2009/800 US$/ha/y Ecosystem Market Pla - Other eco-assets (eg. salinity credits, wetland banking, high-rise buildings(!)) 3. Private market arrangements [PES payment for use of ES] - User fees (eg. resources (water), eco-tourism, bioprospecting) - Biorights (compensate local people for not damaging ES, i.e cons.easem/perrier) -Ecolabelling: Cert.Agr.Products (40 billion $ 2008/2,5% of total market) FSC: 5 billion, Fair Trade, etc)
