IUFRO Congress Spotlight #67 - Tapping the potential of restoring
disturbed tropical forests
*IUFRO Spotlight issues up to September 2019 will primarily focus on the
XXV IUFRO World Congress that will take place on 29 September-5 October
2019 in Curitiba, Brazil.*
*Individual Congress sessions will be highlighted in order to draw
attention to the broader Congress themes, the wide variety of topics that
will be addressed at the Congress and their importance on a regional and
global scale.*

Since the 1980s most deforestation globally has occurred in tropical
countries – Africa, South America and Asia. The high rate of deforestation
and degradation contributes to the disappearance of 13 million hectares of
tropical forests each year.
The effects of deforestation have, over time, led to immense areas of
secondary and degraded forests.
This fall, at the 2019 IUFRO World Congress in Curitiba, Brazil a session
entitled: Will active restoration of Secondary and Degraded Forests (SDFs)
help to address sustainably the gap between wood demand and supply? will
examine ways to address the challenge of restoration in secondary and
degraded tropical forests.
The session, organized by Dr. Marie Ange Ngo Bieng and Dr. Plinio Sist, of
CIRAD (Dr. Sist is also Coordinator of IUFRO's Research Group Tropical and
Subtropical Silviculture) and Dr. Bryan Finegan of CATIE, (and Deputy
Coordinator of IUFRO's Forest Biodiversity Research Group) will focus on
restoring SDFs as a way to protect the remaining natural tropical forests
and also as a way to address the growing gap between wood demand and supply
in a sustainable fashion.
There are several partly overlapping definitions of secondary and degraded
forests. Secondary forests are forests regenerating largely through natural
processes after significant human and-or natural disturbance resulting in
major differences in forest structure and-or species composition with
respect to nearby primary forests on similar sites. More generally, a
degraded forest delivers a reduced supply of goods and services from a
given site and maintains only limited biological diversity.
The reasons for concentrating on tropical forest restoration are simple,
Dr. Ngo Bieng said. Tropical forests are both crucial and endangered. They
account for nearly half of the world's forest ecosystems – 1,770 million
hectares. They draw in carbon dioxide and emit oxygen and have, for good
reason, been called the "lungs of the planet".
Some 50-70% of species living in terrestrial environments are housed in
those forests, which play a crucial role in providing, among other things,
vital ecosystem services, drinking water, and woody and non-timber forest
products.
And about 2/3 of that forest area is considered SDF, so restoring and
utilizing SDFs in sustainable, productive ways makes a lot of sense.
"SDFs supply firewood and non-wood forest products but have rarely been
considered for their potential for timber production," Dr. Ngo Bieng said.
"Although they have been heavily exploited in the past and currently are
very poor in terms of commercial timber stocks, growing commercial timber
trees in SDFs is possible, though variable, depending on local conditions.
"But," she went on, "these tropical SDFs could contribute more to timber
supply and forest environmental services. We propose concepts for
sustainable timber production in SDFs in the tropics. It adds value to
these types of often-neglected forests."
Dr. Ngo Bieng said their session will look at three main things:
- the increase in future wood demand worldwide and the related urgent
need to find alternative sustainable wood sources;
- the potential of SDFs in that context and the current challenges
related to wood production in tropical SDFs in different countries; and
- case studies of active restoration associated with successful wood
production and commercialization of timber in SDFs for higher value end
products.
The session organizers recognize that there are significant challenges
between them and a successful restoration initiative. Among them:
re-establishing productive forest systems where there are serious
biophysical limitations; initiating relevant silvicultural practices for
effective restoration; weak institutional frameworks and-or a lack of
sectoral policies; and competing visions of how the landscape should be
used.
Dr. Ngo Bieng is hopeful that the "international context" which has
underlined an increasing demand for wood products can provide opportunities
to move forward. The increase in demand for wood calls for sustainable
alternative wood production.
"The remaining logged and production forests will not, by themselves, be
able to fulfill the increased demand for tropical wood products while also
playing a major role in providing environmental services," she said.
"We urgently need alternative sustainable wood sources."
She noted that her colleague, Dr. Sist, is involved in the Tropical managed
Forests Observatory (TmFO) initiative. "It's a pan-tropical network
examining the long-term effects of logging on tropical forest ecosystems.
"Their findings will provide policy-makers and foresters guidance in
sustainable forest management and conservation of tropical forests. That
knowledge will certainly be useful for the future management of productive
SDFs," she said.

*IUFRO Spotlight* is an initiative of the International Union of Forest
Research Organizations. Its aim is to introduce, in a timely fashion,
significant findings in forest research from IUFRO member organizations
and/or involving IUFRO officeholders to a worldwide network of decision
makers, policy makers and researchers.
*The findings reported here are submitted by IUFRO Member Organizations.
IUFRO is pleased to highlight and circulate these findings to a broad
audience but, in doing so, acts only as a conduit. The quality and accuracy
of the reports are the responsibility of the member organization and the
authors.*
Suggestions for reports and findings that could be promoted through *IUFRO
Spotlight* are encouraged. To be considered, reports should be fresh, have
policy implications and be applicable to more than one country. If you
would like to have a publication highlighted by *Spotlight*, *contact:
Gerda Wolfrum, wolfrum(at)iufro.org <wolfrum(a)iufro.org>*g>*.
The International Union of Forest Research Organizations (IUFRO) is the
only worldwide organization devoted to forest research and related
sciences. Its members are research institutions, universities, and
individual scientists as well as decision-making authorities and other
stakeholders with a focus on forests and trees. Visit:
