Why is valuation of ecosystem services important ?
Forest Trends, 2010

Uses of Ecosystem Valuation / Economic Analysis
Raise awareness Improve decision making (policies,
planning, projects) Requires understanding, measuring and
quantifying the trade-offs Facilitate effective management
including sustainable financing options Valuation underpins the design of eco-
compensation mechanisms such as PES
Ecosystems, PAs & ecosystem services5
Protected Areas are the cornerstone of conservation policy and provide multiple benefits’ (TEEB for Policy Makers)
PAs provide the best continuous natural habitats for ecosystems to be able to function and continue to deliver these services

Mainstreaming ecosystem services
Understanding the provision of ecosystem services (Quantification)
Understanding the benefits to human well-being from ecosystem services (Valuation)
Creating incentives for sustainable provision of ecosystem services (Policy/Governance)
Typology of Potential Ecosystem Services
ES Type Service Benefit / outcome
Provisioning Servic

Educational Education
Recreation and ecotourism Recreational fishing and hunting, birdwatching, paragliding, hiking, diving, sailing, canoeing, holiday destination (aesthetic views), archeological ruins (recreational value)

Integrating Economic Valuation into Wetland Decision Making (Bann et al, 2010)
Step 1: Define issue and context
Step 2: Define the scope of the economic assessment
Step 3: Undertake valuation of ecosystem services
Step 4: Analysis of findings
Step 5: Report and dissemination
Six Steps for including ecosystem services in local/regional policy (TEEB, 2010)
1. Specify & agree the policy issue with stakeholders
2. Identify which services are most relevant
3.Define information needs and select appropriate methods
4. Have ecosystem services assessed5. Identify and appraise policy options6. Assess distributional impacts
What is the decision making context ?
Decision context Possible decision-making questions for wetlands resource management
Policy and project analysis (setting priorities; appraisal of investment projects, policies, regulations and standards)
What is the best wetland project, policy, management option? What are the costs of unsustainable use? Is there a case for conservation actions?What sectors are most dependent on wetlands?How much does the wetland contribute to the economy?How much should be spent on management?
Pricing and allocation What is the appropriate level of a user tariff / PES? What uses should water abstracted from wetlands be allocated to?
Legal damage assessment
What is the value of environmental damages? What scale of compensation for damage is justified?

Overview of valuation methods Valuation method Ecosystem service valuedMarket prices Marketed products – timber, fishCost based approaches
Depends on existence of relevant market for the ecosystem service in question. E.g. expenditure on water filtration as proxy for value of water pollution damages
Production function approaches
Environmental services that serve as input to market products e.g. soil fertility contributions to agricultural productivity
Hedonic pricing Attributes that can be appreciated by potential buyers, e.g. PAs contribute to air quality, visual amenity, landscape
Travel cost All ecosystem services that contribute to recreational experience
Stated Preferences approaches
All
Value transfer All

Value
Valuation of Ecosystem Services, Phewa Lake Nepal
Total Gross Annual value is US$ 45.41 million (US$ 104, 392/ha of the lake) 87.8% is from Tourism and Recreation 3.2% from Provisioning services (food, irrigation and
hydro)
Management of the lake is key to the Tourism Sector. About 40% international tourists or 200,000 tourists visit
Pokhara in a year Similar number of Nepali tourists also visit Foreign Exchange earning from International Tourism is
Nrs 29 billion in 2009 or 3% of GDP
Demonstrating value for money (1)In New York, Catskills (Perrot-Maitre and
Davis 2001). Payments to maintain water purification
services in the Catskills watershed (US$ 1-1.5 billion)
This is significantly less than the estimated cost of a filtration plant (US$ 6-8 billion plus US$ 300-500 million/year operating costs).
Taxpayers’ water bills went up by 9% instead of doubling
Demonstrating value for money (2) Venezuela - the national protected area
system prevents sedimentation that if left unattended could reduce farm earnings by around US$ 3.5 million/year (Pabon-Zamora et al. 2008)
Mangroves in Vietnam. Restoring & protecting nearly 12,000 hectares of mangroves cost US$ 1.1 million but saved annual expenditures on dyke maintenance of US$ 7.3 million. (Tallis et al. 2008)
Assessing the benefits of not converting a floodplain in Delhi
Around 3,250 ha of floodplain between the Yamuna River and the landmass in Delhi offer benefits such as provision of water, fodder, fisheries, and recreation.
Pressures to convert the floodplain for housing & industry,
A range of ecosystem services estimated at US$ 843/ha/year (2007 prices) (Kumar 2001),
Higher than the opportunity costs of conservation, justifying the maintenance of the floodplain.
The Delhi Government halted the embankment plan of Yamuna
The Wetlands Reserve Program, USA A voluntary program offering landowners an opportunity
to establish long-term conservation and wildlife protection in exchange for retiring eligible land from cultivation.
The USDA Natural Resources Conservation Service (NRCS) goal is to achieve the greatest wetland functions and values, along with optimum wildlife habitat, on every acre enrolled in the program.
There were 229 contracts in 1992 and 485 contracts in 2008.
Funding for the WRP program was fairly steady between 2002 and 2008, averaging roughly US$246 million per year.

Key messages ! Wetland Protected Areas represent
natural capital If they are properly managed they provide
a flow of vital services – water, flood control and recreation
If they are badly managed these benefits are reduced or lost at an economic cost to society
Sustainable management requires the integration of ecosystem services into planning to ensure trade-offs are properly evaluated
Ecosystem services valuation underpins the design of eco-compensation mechanisms
