Achieving a goal of sustainable forestry will probably take time as people
agree on what sustainability means at the global, subcontinental, national,
and regional scales. Comparing seven criteria of sustainable forestry with
information at different scales suggests that the world could practice sus
tainable forestry, but there are currently imbalances in economic developme
nt, forest area change, harvesting and wood-use rates and purposes, and oth
er factors that are impeding it. Different countries could adopt different
policies and practices to help correct these imbalances. Until a globally a
greed-upon set of policies and practices is established, each country will
probably define its best efforts toward sustaining its "fair share" of the
criteria. Managing large areas of forests for many values with some areas r
eserved in each forest type will probably be more ecologically, socially, a
nd financially effective than having small areas of plantations supply the
world's wood - and the rest of the world's forests set aside as reserves. D
isseminating accurate information, addressing sustainability at different s
cales, addressing rural/urban lifestyles, increasing uses for the very abun
dant, environmentally sound wood, incorporating the other values into the e
conomic system, and avoiding central planning are primary issues and challe
nges to sustainability. Technology, policies, and various organizations can
be marshalled, and each organization can play a constructive, rewarding ro
le.
