Beyond Deforestation: Restoring Forests and
Ecosystem Services on Degraded Lands
Robin L. Chazdon

Abstract of article :
Despite continued forest conversion and degradation, forest cover is
increasing in countries across the globe. New forests are
regenerating on former agricultural land, and forest plantations are
being established for commercial and restoration purposes.
Plantations and restored forests can improve ecosystem services and
enhance biodiversity conservation, but will not match the composition
and structure of the original forest cover. Approaches to restoring
forest ecosystems depend strongly on levels of forest and soil
degradation, residual vegetation, and desired restoration outcomes.
Opportunities abound to combine ambitious forest restoration and
regeneration goals with sustainable rural livelihoods and community
participation. New forests will require adaptive management as
dynamic, resilient systems that can withstand stresses of climate
change, habitat fragmentation, and other anthropogenic effects.

The Future of Forests

This week’s issue of Science is a special issue on forests.
Here’s an overview of the many articles  in it.

Introduction to special issue
The Future of Forests
Andrew Sugden, Jesse Smith, Elizabeth Pennisi

Forests have had a pervasive influence on the evolution of
terrestrial life and continue to provide important feedbacks to the
physical environment, notably climate. Today, studies of the world’s
forests are taking place against a backdrop of unprecedented change,
largely resulting either directly or indirectly from human activity.
In this special issue, we focus particularly on the future of forests
in light of these changes.

Climate Policy: Too Little, Too Late?

A reviewer at Real Climate (briefly) pooh-poohed
Six Degrees, the recent book by Mark Lynas,
author of the op-ed  below.  Lynas  emailed the
reviewer with questions.  The reviewer then read
(or re-read?)  Lynas’ book, and retracted the
dismissal in a subsequent Real Climate posting,
saying that Lynas’ Six Degrees is actually very
well-based on the available science.

Unfortunately, most climate policy under current
consideration still isn’t. Below, Lynas looks at
the still-popular Kyoto-based model as one of 3
policy options that merit examination, and
question.

” … conventional wisdom from governments and
environmental groups alike insists that ‘Kyoto is
the only game in town’, and that proposing any
alternative is dangerous heresy.”

“If current policy continues to fail – along the
lines of the “agree and ignore” scenario – then
50% to 80% of all species on earth could be
driven to extinction by the magnitude and
rapidity of warming, and much of the planet’s
surface leftuninhabitable to humans. Billions,
not millions, of people would be displaced.”
