What are the services produced by watersheds?
• Water flow regulation
• Water quality control, chemical, biological and solids
• Maintenance of aquatic habitats
• Beware the forest – water myths
Who are the stakeholders?
• Anybody and everybody who is involved with land use and water issues
- Government; P&L, potential buyers- Land managers; large, small, private, communal,
protected- Private sector; buyers of services- Public; water users
What kind of payments have been used?
• Direct negotiations between buyers and sellers• Intermediary facilitated transactions between
buyers and sellers• Pooled transactions that spread the risk among
buyer• Auctions that engender a level of competition• Retail based incentives
Public vs Private Payments
• Public payments:
- use money from the tax payer (no new money)
- politically susceptible
- lower efficacy
- example: China, sloping lands conversion programme
• Private payments
- cost effective solution to core problem
- new source of money for resource management
- potentially more sustainable
- example: HEP companies in Costa Rica
Spatial considerations
• Watershed services are spatially restricted- are bilateral, mutually-negotiated agreements
between ecosystem service users and providers (Wunder and Vargas).
- Water is often highly politicised, terminology becomes important
- Markets, payments, rewards, compensation
What are the key challenges?
• Hydrological basis of PWS
- is there a service?
• Economic basis of PWS
- Is there a deal?
• Policy and legal basis of PWS
- is there a policy and legal framework?
The hydrological basis for PWS
• Highly complex landuse – water relationships
• Need to consider ground water and surface water
• Scale is an important consideration –what can be measured and by whom?
The economic basis for PWS
• Assumes a gradient of wealth – poor landusers live upstream, wealthy downstream
• In many watersheds there will be no buyers of the service
• Landscapes are typically highly complex, multiple landuses and landusers
• Multiple and conflicting objectives
The social basis for PWS
• Organisations: complex organisations with multiple and competing claims over land and water (eg Africa political vs traditional)
• Institutions or rules: typically sectoral based legislation (land, water, wildlife, forestry) that are not integrated and are primarily control based.
• Legislation that stimulates (eg New York)• Legislation that leads (Costa Rica)
Can PWS address poverty?
• Nature of poverty: structural, governance, other• Landless: typically very poor and landless – aim
for a neutral impact.• Complex landscapes are resilient, changes must
not destroy the resilience.• Positive examples - mostly from Costa Rica where
there are very high payments.• Negative examples – China and the impact of
grain to green.
