Poole Harbour

Poole Harbour PES scheme• Local authorities object to paying farmers for reductions in agricultural

nitrogen pollution.

• Use of development funds to address agricultural pollution is unfair and politically unacceptable given that agriculture contributes 85% of total nitrogen load

• Farmers and landowners are unwilling to accept long-term contracts for nutrient reduction measures.

• Collective action is a significant challenge, particularly when … spatial scales are large (e.g., water quality and flood risk services)… there are many affected actors

Improving water quality by nutrient offsetting

Oil Palm in Cameroon

Constraints to productivity and profitability

• Unreliable water supply• Expensive agricultural inputs• Ageing plantations• Lack of good quality seedlings• Low milling efficiency• Theft of fruit• Lack of skilled and local labour• Conflicts over tenure• Government policies• Declining prices

Opportunities of high prices

Company – smallholder interactions

Opportunities provided by:

Improved millingSubsidized fertilizersAccess to high quality seedlings

Opportunities limited by:

Inefficient millingExpensive fertilizersPoor quality seedlings

Implications of low prices

Investing in large concessions is less attractive

Power over ecosystem services is not

distributed equally

Endogenous and exogenous pressures shape land use change, and affect the relative merits

of ecosystem service strategies

There are winners and losers, always

Benefits of ecosystem services are not

distributed equally

Contexts are complex … and changeable

and integrate our thinking across a complex world of social and political inequalities and trade-offs

We need to look well beyond our disciplinary interests …

Good luck!
