Support to National Forest Assessments
Why is it needed? (cont)
• To support policy and decision making processes
• To support sustainable development programmes
• To improve the productive, protective, environmental and
social functions of forests and trees outside forests.
• To protect forests from degradation and deforestation.
• To integrate forest resources in land use planning and
management.

How is it done?
Objectives
 Capacity building: Develop/strengthen national capacity in
assessment of forest and TOF resources, information management
and long term monitoring
 Assessment:
Assess forest and TOF resources for NATIONAL level decision making:




State of resources (areas distribution, volume, biomass, biodiversity, etc);
Non wood forest products and services;
Management, use and users of resources;
Role of forests and trees in food security
 Monitoring: Set up a long term monitoring system of resources .
 Experience sharing: With FAO coordination/leadership countries
benefit from each other experiences.

Method
 Low intensity field sampling (100 - 1000 sample sites/country)
 Permanent plots for long term monitoring
 Data collection through field measurements and interviews
 Variables covering large range of forest and TOF characteristics
(volume, management, benefits...)
 NFA approach adjusted to national context through participatory
process.
 Classification system defined according to each country’s specific
needs and harmonized with international reporting systems
 Possible integration of other land use resources
(agriculture, livestock, mining, fishery...) .

Knowledge reference for NFAs
• FAO-IUFRO initiative: implemented
University of Agricultural Sciences;
in collaboration with the Swedish
• Objective: improve access, world-wide and in several languages, to stateof-the-art knowledge on a wide range of subjects relevant to national forest
assessments;
• To be developed by:
 Lead authors from the IUFRO network. Each chapter will have one lead
author and co-authors.
 Representatives from countries for case studies; and
 Institutions such FAO, IUFRO and the Department of Forest Resource
Management and Geomatics of the Swedish University of Agricultural
Sciences.
