Are we oversimplifying societal complexities?

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

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!
