Support to National Forest Assessments
National Forest Assessment:
A national process to collect, manage, analyse and make available information on forest resources, their management and use covering the entire country, including also analysis, evaluations and scenario development for use e.g. in policy processes
National Forest Inventory:
The principal activity to collect data within a National Forest Assessment. A NFI is, often, based on systematic field sampling and can be complemented by remote sensing components.
Kotka IV, 2002
1. What is national forest assessment?
Support to National Forest Assessments
• Demand for forest information is continually increasing and is
becoming complex;
• Today, national policies are developed to address the multiple
functions of forests and trees;
• International processes are requesting countries to report regularly on
a variety of forest related issues.
• Civil society is increasingly concerned and wants to be informed.
2. Why is it needed?
In many countries,
• The information is frequently outdated, partial or subjective;
• The precision and accuracy of the national data is unknown in
most cases;
• Consequently scenario development and planning may be
inaccurate.
2. Why is it needed? (Cont.)

2. Why is it needed? (Cont.)
Develop/strengthen national capacity in assessment of forest and TOF resources.
Assess forest and TOF resources for NNATIONALAL 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
Establish long term monitoring system of resources.
Promote sharing of experience between countries.
Improve awareness of and knowledge about the multiple functions of forests and trees
3. How is it done?3.1 Objectives
Support to National Forest Assessments
3.1 Objectives (cont)
Harmonize land use classification systems & forest related definitions with international reporting requirements.
Encourage partnerships between national institutions and with international agencies.
Provide guidance to future actions: e.g. policy development, detailed inventories, etc.
Support national programmes of poverty alleviation and gender equity.
Establish stability over time of methods and results.
Country commitment required for sustainability of monitoring programme.
Support to National Forest Assessments
Design Criteria
Information needs
Cost effectiveness
Rapidity of data collection/update procedures
Accuracy and consistency of output data (in space and in time)
Flexibility for adaptations to various national requirements
Compatibility of output with existing national information systems
Harmonization to international standards
3.2 Concept
Support to National Forest Assessments
3.3 Methods
Low intensity field sampling (100 - 1000 sample sites/country)
Permanent plots for long term monitoring
Data collection through field measurements and interviews
Wide range of variables of forest and TOF characteristics
Information needs defined through participatory process (stakeholders and users).
Classification system defined on countries’ specific needs and harmonized with international reporting requirements
Possible integration of other land use resources (agriculture, livestock, mining, fishery...) .

3.3 Methods (Cont)
Linkage to:
National forest programmes;
global themes (extent of forests and OWL, contribution to global carbon cycle, forest ecosystem health and vitality, biological diversity, productive functions, protective functions, social functions, economic functions) .
Millennium Development Goals, especially Goal 1 and Goal 7,Target 9.

A key factor for policy development and monitoring is access to reliable, relevant and cost-effective land use information.
Forests and trees are integral components of land management systems. They influence, and are influenced by, other land uses
It is therefore logical, from a national policy perspective, to approach sustainable land management as a multiple-goal planning problem, where a large number of objectives are to be addressed together.
The integrated land use assessment of Zambia includes variables on forests and trees, agriculture, livestock.

4. Knowledge reference for NFAs
• FAO-IUFRO initiative: implemented in collaboration with the Swedish University of Agricultural Sciences;
• Objective: improve access, world-wide and in several languages, to state-of-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.
