Forests are a key component of sustainable development
Sustainable forest management (SFM)
has become the pillar of forest policy at national,
regional or global scale
but SFM is a complex issue and
implementation requires improved
knowledge within a multidisciplinary
framework
Research
can contribute to a large extent in providing the rationale and
the background for such an integrated management of forests
Scientific challenges
-functional understanding by generalisation
and integration of approaches
-multidisciplinary teams
-multiscale approaches
SFM relies on
- multifunctionality
- dialogue
- follow up
Shifting emphasis on the role and management of forests
Over past centuries, forests produced goods and
management was about growth and yield.
Over the past decades, other forest functions became
important and the sustainability concepts in forestry
expanded from sustained yield towards management for
sustainable multifunctional use.
sustained yield (wood) >>> sustainable natural resource management
or ecosystem management
- overexploitation, degeneration, disappearence of forest
- importance of goods and services other then timber
- awareness that forests play key-role at local, regional and
global scale in regulating water, nutrient and carbon flows;
forests affect atmospheric composition, water resources,
biodiversity, global climate, gene flows, etc
Forest management deals with systems developing over large
temporal and spatial scales

Sustainable development: progress that meets the needs of the present
without compromising the ability of future generations to meet their own
needs.
Three dimensions in sustainable development
- ecological sustainability
- economic feasibility
- socio-political acceptability
The objective is to maximise these goals across the biological, economic
and social systems.
Indicators are necessary to put into effect the concept of sustainability
and to introduce it to policy making and monitoring processes
One approach is to develop pressure-state-response indicators and this is
being applied to different sectors: agricultural, forest, industrial, energy
The Forest Principles set out in UNCED triggered international
activities towards clarifying the term “sustainable forest management”,
namely in terms of operational definition.
Operationalisation is still underway and the main outcomes are sets of
criteria and indicators (C&I) to determine the general objectives or
values that must be maintained in SFM as well as methods of
implementing SFM.
The global focus of SFM is on the definition of C&I for the goals of
SFM and what management processes are necessary
Criteria : categories of conditions or processes by which SFM
may be assessed; clearly specified elements that define the
scope and key outputs of SFM; they reflect a series of broadly
held values related to the environmental, economic and social
functions of the forets; they have a set of related indicators
that are monitored periodically to assess change.
Indicator : a quantitative or qualitative measure of an aspect of
the criterion to show current performance and trends in
performance; they are chosen to provide measurable features of
the criteria.
Criteria for sustainable forest
management
Development of the first criteria and indicators for SFM began in
the late 1980’ by ITTO (International Timber Trade Organization)
Three programmes have been developed through international
cooperative processes to define sets of C&I for SFM
- Montreal Process criteria and indicators (MP C&I)
- European criteria and indicators (pan-European C&I)
- The ITTO Manual on criteria and indicators (ITTO C&I)

Implementing sustainable forest management
is problematical and difficult
Balancing ecological and socio-economic benefits
SFM is a balance
or trade off of
ecological values
against social and
economic values
Social, economic and
cultural benefits
Ecological values
Optimising socio-economic benefits within

Sustainable forest management
The C&I approach to SFM is internationally accepted at
national level by the different stakeholders (i.e. research,
policy makers, government bodies, economic partners) and
work is actively underway towards system harmonisation,
implementation, data gathering, monitoring and assessment
procedures.
But very little was developed at the level of:
- Forest Management Unit
- Small scale community forest systems
and locally relevant criteria and applicable indicators will
have to be designed (i.e. including autochthonous
indicators).
Also indicators have not been designed for certification of
SFM.
The C&I constitute a monitoring and measurement
framework and do not have any accompanying standards.
These will have to be the object of public forest policy and
regulation.
