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 Photos by Patrice Levang

Declining palm oil price Palm oil monthly price: US$ per metric tonne 20102011201320122014 $1240 $900 $860 $700 $1160 $634

Opportunities of high prices Company – smallholder interactions Opportunities provided by: Improved milling Subsidized fertilizers Access to high quality seedlings Opportunities limited by: Inefficient millingExpensive fertilizers Poor quality seedlings Implications of low prices Investing in large concessions is less attractive

The Complexities of Decision-Making Land-use decisions Market opportunities Access to market Prices and demand Processing opportunities Incentives Government subsidy schemes Access to credit and materials Payment for ES schemes Formal institutions Legal arrangements governing access to land and resources Property rights to land and resources Informal Institutions Customary rules, norms, beliefs governing access to land and resources Ecological factors Productivity, soil, water, biodiversity, risk reduction Household factors Age, gender, size, labour, income … ExogenousEndogenous

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!
