1Genuine Progress Index for Atlantic CanadaTHE
GPI FOREST ACCOUNTS FOR NOVA SCOTIAHalifax,
December 7, 2001
2What kind of world are we leaving to our children?
- Less fish in the oceans
- Fewer old forests
- Depleted soils
- Fewer species of animals and plants
- A dangerously warming world
- Is this progress?
3Are we sending the wrong message?
- Crime, pollution, sickness, greenhouse gases can
make economy grow. - Longer work hours and stress make it grow
- Distribution of income ignored
4GDP and Natural Capital
- GDP counts resource depletion as economic gain
the more trees we cut, the more fish we sell, the
faster we deplete our natural wealth the more
the economy will grow, and the better off we
are assumed to be. - Like factory owner selling machinery
5In the Genuine Progress Index
- Crime, pollution, sickness, greenhouse gas
emissions, counted as costs not gain - Unpaid work, equity, free time valued
- Natural resources are seen as capital assets
subject to depreciation and requiring
re-investment.
6GPI Natural Resource Accounts Valuing Natural
Capital
- For example, forest functions / values include
- Preventing soil erosion and nutrient leaching
- Protecting water quality and flows
- Climate regulation/carbon sequestration
- Providing habitat for the full array of native
biodiversity - Recreation, tourism, aesthetic quality
- Providing timber
- Healthy Forest

14Old Forests Store More Carbon A new study
published in Science, reported that ...
replacing old-growth forest by young stands ...
will lead to massive carbon losses to the
atmosphere mainly by replacing a large pool with
a minute pool of regrowth and by reducing the
flux into a permanent pool of soil organic
matter. (Schulze et. al. 2000)

27Machinery Costs for Large-Scale Harvesting

29Clearcut harvesting and loss of natural age and
species diversity have resulted in loss of
- valuable tree species
- wide diameter and clear lumber that fetch premium
market prices - resilience and resistance to insect infestation
- wildlife sensitive to forest fragmentation and
forest conversion - forest recreation and tourism opportunities
30This represents a substantial depreciation of a
valuable natural capital asset.
- degraded water quality and created unstable
hydrological regimes - soil degradation and the leaching of nutrients
that can affect future timber productivity - a substantial decline in carbon storage capacity
a decline in other essential forest ecosystem
services.
31The Good News Volume 2 Best Forestry Practices
in N. S.
- Selection harvesting increases forest value and
provides more jobs - Shift to value-added creates more jobs
- Restoration forestry is a good investment
- What incentives can encourage restoration
32Costs of Restoration
- Pictou Landing 110/ha/yr
- Frith 35/ha/yr
- Dreschers estimates 80-150/ha/yr
- Menominee Forest Enterprises 750-1,500/ha/yr
- Algonquin Park 0.00
