Payment for Ecosystem Services (PES) as a means of sharing environmental benefits: How numbers provide the
basis for dialogue in water-based payment schemes in the Andes
Andy Jarvis, Marcela Quintero, Nathalia Uribe, Ruben-Dario Estrada
Contents
• The importance of numbers• Our principles• Three examples of science-
based establishment of water-based PES in the Andes– Chingaza– Moyobamba– Fuquene
• Outlook
CIAT’s work on Ecosystem services
• Very focussed on externalities• ES that have a national, regional or international
market– Aboveground carbon– Water
• Putting the numbers on ES flows in an integrated manner
• Learning from broad range of cases• Enabling the poor to engage and benefit from
emerging ES market opportunities
Reasons for Failures in PES
• High failure rate of PES, though Latin America has been a test-bed
• Unreal expectations for PES• Lack of equity in benefit sharing• Poor or inappropriate governance
structures• Low perceived impact in terms of ES
benefits• High potential to create conflict,
rather than resolve itNumbers as a basis for dialogue
Externalities• An externality is the beneficial
or damaging effect caused on a third party by the decision of other(s)
• Those who cause the effect do not receive any compensation for the generated benefit, or do not assume the cost of the damaging effect
• Environmental externality is determined by the environmental effects of a human activity
• When the effect is positive the externality is considered as an environmental service
Example: Watershed services: regulation of streamflows and retention of sediments achieved by land uses and management

Trade off Analysis
Evaluation of land use alternatives for providing environmental services
Examples of land use evaluation
• Conservation agriculture (Colombia)– Increases net
incomes, potato production, social benefits, sediment retention and employment; and reduce production costs.
– However the initial investment can not be afforded with current small farmers cash flows

Tradeoffs: Maximum environmental benefit at cost of rural smallholder poor?
CONCLUSIONS
• PES provide a new paradigm for natural resource management….
• …but also a new paradigm for addressing concerns of rural poverty
• Establishment of schemes must be based on sound, integrative analysis of natural, social and economic benefits
• In CIAT we’re very interested in matching with partners to generate rural livelihoods through PES. We can provide natural, economic and social analysese, and you…..
