1. Markets for Ecosystem Services (ES) David Zilberman University of California Berkeley

2. What do we speak about? Alternative ways of selling ES  Formal Markets (Carbon)  Direct deals between two parties  auctions  Subsidies & government payment

3. Categories of Environmental Services (ES)  Conservation&Preservation  Storage and stabilization ( e.g water,carbon )  Risk reduction ( flood control, protection form fire)  Natural resources quality enhancement ( soil,water)  Amenity creation-  restoration  Enhancement

4. Environmental Services & Land Use  Working land programs-promoting green practices  Conversion of lands to “greener” use  From farming to forest  Prevention of land use conversions  Controlling development

5. The Multidimensionality of ES  The same land may provide a multitude of ES  Some ES are provided simultaneously others are not  Growing Wetland conflicts with native plants  Soil erosion and wind erosion are complementary  ES may provide regional, national & global benefits  Benefits of ES vary across individuals &groups  Bird watchers & hunters benefit from better bird habitat  All gain from flood control- gains vary by location

7. Implication of “Beneficiary pay”  Government pays for public good aspects -  utilized by many  No exclusion - e.g Existence value  Private agencies should pay for private benefits. BUT  Private willingness to pay for ES is understated because it emits public goods  There is a role for public-private cooperation  Matching fund  Tax credit

8. Selling ES in markets vs. special trades Market Low transaction cost Standard product Large number of buyers Minimal contact of buyer and seller Special deal Tailor product to buyers’ needs Local small number of potential partner Needs a way to link buyer to seller green E-bay

9. Elements of implementation  Measurement  ES output meeting well defined standards  Monitoring and enforcement  Unbundling  Heterogeneity  Correlation  Targeting  Role of government  Third party

10. Measurement  Buyers and sellers need to know  What is delivered - when - for what price  Deliverables can be outcomes or actions  Must be easily measurable  Simplicity and common sense are essential  ES is controlled by the worker in the field  Not the scientist is the lab. Clever use of new IT can improve measurement accounting and monitoring

11. The reasons for ES product standards ( Being commodities not unique products)  Buyers want  to know what they buy  To sell it when they want ( liquidity)  Certification by trusted agency All associated with having ES meeting standards. Also  Low transaction cost  High volume of trading

12. Monitoring and Enforcement  ES are frequently generated on large parcels of land over long period of time  Farmers can easily cut corners  Inspection backed by action will lead to improved ES quality  justify higher prices  Can be part of certification program  Monitoring allows establishing buyers insurance plans ( Guaranteeing delivery and compensation)

13. ES markets allow selling bundles of ES  A field may generate various types of ES  Potential buyer may be interested in only part of the package  The Land owner’s gain will increase If they can sell different types of ES to to different buyers  A well functioning ES market results in a pricing of individual ES that will increase the flexibility of the buyers and sellers

14. Heterogeneity  Lands vary in their productivity and ES generation  Sometimes 90% of certain ES is provided by 10% land  Both buyers and sellers benefit when buyer who appreciate certain ES are able to get them-part of efficient buying and selling strategies  Buying the lands with the best ES is not always the best strategy- best to buy ES who provide highest value Per dollar

15. Targeting strategies A buyer with given budget may choose  Acreage maximization given the budget This strategy is preferred by sellers It is optimal only when cheapest lands provide most ES.  Benefits targeting Purchase the highest quality lands within budget -best for buyers if there is lower variability of productivity than ES among lands  Benefit /cost Targeting Purchase lands with the highest highest per dollars given the budget-always works for buyers

16. Third parties Designers of ES programs need to be aware that  taking lands out of production may result in increase ag prices  May backfire leading to farming of previously idle lands- thus may need to pay for prevention  Reduced farm activities may reduce tax base  Landowners may gain but operators and other lose
