2Ecological Goods Services are
- defined as components or services provided by
the natural environment that benefit people, e.g.
clean water, clean air, biodiversity, quality
landscapes. - associated with particular benefits that human
populations derive, directly or indirectly, e.g.
aesthetics, recreation, health, damage avoidance. - Healthy agro-ecosystems can provide numerous EGS
that produce these benefits.
3Public Policy Issues
- Reasons to consider EGS policy
- Accounting for EGS is important to public policy
because they contribute significantly to human
welfare and are not captured in existing welfare
accounts - Producers are paid for market goods, but rarely
for public goods - May overuse resources and under-supply ecological
services - Reasons to be careful
- Other sectors liable for damage caused receive no
particular EGS support - Scientific and economic information is often
lacking.

P from these
5when spread over this
6affect some point of impact?
- If society values environmental services
(positive externalities/risk mitigation) from
agriculture, - How extensive are these benefits? (scale)
- How expensive are these benefits? (cost)
- How valuable are these benefits? (social value)
- How can farmers be encouraged to produce more of
these benefits? (policy incentives) - We have generally adopted a watershed focus
7Spatial scales of metrics that relate to
ecosystem services from agriculture.

10The Eight EGS Pilots
- Evaluation of EGS (costs/benefits)
- Testing acreage payments
- EFP Enhancement and Group Planning
- Ducks Unlimited Canada Manitoba
- Identification and valuation of EGS provided by
wetlands in South Tobacco Creek - Keystone Agricultural Producers - Manitoba
- Alternate Land Use Services (ALUS)
- Coopérative de Solidarité, Riviére-Aux Brochets -
Quebec - Farmers Contribution to the Production of EGS
in the Sub-Basins of Missisquoi Bay
11Pilot projects will help answer the tough
questions
- How to measure and place value on public demand
for EGS? - How to ensure results are accountable to the
market place (private buyer) and/or public? - Determine most efficient and effective policy
tools?
12but big challenges remain
- Linking physical changes in complex natural
systems to changes in services valued by people. - Data limitations require innovative techniques to
assess the spatial distribution of benefits. - Adequate approximations are needed for scaling
up.

15Next Steps
- Complete research for the development of EGS
policy framework by - Monitoring the development of pilot projects and
other research within AAFC (WEBs, NAESI) - Integrate economic research with landscape based
research activities - Develop research for EGS policy options to test
effectiveness of particular approaches - Engage other federal departments who are now
becoming interested in EGS policy development
