8 I. Introduction International Background As UNCED introduced the concept of Environmentally Sound and Sustainable Development (ESSD) in 1992 (Rio of Brazil) and Forest Principle, one realized the necessity of evaluation of Temperate and Boreal Forest Sustainability. International society try to develop a tool to monitor, assess and report forest trends at national & global level In 1995, Montreal Process endorsed 7 criteria and 67indicator for Sustainable Forest Management (SFM), now end up with 7 criteria & 54 indicators for implementation of SFM by member countries

9 Domestic Background Framework Act on Forest(2001) Lay down a foundation for Sustainable Forest Management Act on Promotion & Mgt. of Forest Resources Require central government to develop and announce FSI National Forest Plan The Fourth (1998~2007) and the Fifth National Forest Plan( 08~ 17) aimed at Promoting SFM

10 II. Concept & Objective of FSI Development 1. Concept A quantitative score to indicate overall quality & conditions of forest sustainability, taking into account economic, social and environmental conditions at local & national level 2. Objective FSI can assist the nation & local government in making datadriven planning, better policy, program decisions for sustainable forest management through progress evaluation of F. M. To use index as a statistical report ; to formulate forest associated policies, to evaluate the progress of sustainable forest management, to make an estimate and allocate budget, to set up forest management plan and to promote public awareness on forest sustainability

11 III. Process of FSI Development 1. Methodology for Forest Sustainable Index Statistical Formula - Component FSI : I where j ~ X W j j i m j 1 W j ~ X j = number of indicators (m=19) = ratio of indicator value to that of the base year = weight of indicators - Integrated FSI : I n i 1 W i I i where i Wi = number of components (n=3) = weight of components The value of each indicator of the basis year is set at 100, Basis year is 2000 Each indicator is estimated, compared to that of the basis year. Component FSI is the sum of (xj X Wj) FSI (the total index) is the sum of each component FSI X each component weight

12 2. Selection of Criteria and Indicators Forest sustainability is categorized three parts : Forest health, Forest economic viability, & public benefit (social and environmental) Nineteen indicators of three categories were chosen information availability and time variant, policy relevance, representativeness, sensibility and redundancy Forest Health and Vitality(6) % change of forest area to total area % change of mature forest area to total area % change of arboretums area to total forest area % change of forest tending area to forest area % change of undisturbed area to total forest area Forest Economic Viability(7) % of forest area available for timber production Growing stock in forest area available for timber production % of forest area established forest management plan % of net growth to removal amount of products to forest area % of expenditures associated wiith forestry to total budget Social and Environmental Benefits(6) % of protected forest area to forest area Carbon stock of forest biomass to forest area Carbon balance of forest biomass Area of recreation forest /1000 Area of urban forest /1000 % of employment in forest sector to economically active population

13 3. Process of Developing FSI (1) Questionnaire Survey Three hundred seventy seven forestry experts on the area of education, research and administration were surveyed to examine priority among categories and among indicators under categories Item Total Administration Research Academia Sample Return Response rate 45% 41% 83% 17% Weight by Pairwise Comparison Based on the result of survey, weight assignment was done through pairwise comparison against each indicator

14 (2) Result of Analysis Weight by Component Forest Health and vitality Forest Economis Viability Social and Environmental Benfits

15 Weight of Indicators - Forest Health and vitality Indicator Weight Percentage of forest area to total area Percentage of mature forest area to forest area Percentage of arboretums area to forest area Percentage of forest area protected for genetic conservation Percentage of forest tending area to forest area Percentage of forest disturbed area Total 1.000

16 - Forest Economic Vitality Indicator Weight Percentage of forest area available for timber production Growing stock in forest area available for timber production Percentage of forest area established forest management plan Amount of forest products to forest area Percentage of net growth to removal Percentage of expenditures associated with forestry to total budget Percentage of forest contribution to GDP Total 1.000

17 - Social & Environmental Benefits of Forest Indicator Weight Percentage of protected forest area to forest area Carbon stock of forest biomass Carbon balance of forest biomass Recreation forest area to population Urban forest area to population Percentage of employment in the forest sector to economically active population Total 1.000

18 IV. Evaluation of Forest Sustainability using FSI 1. Trend of FSI at National Level Increase to139.1 in 2007 from 100in 2000 : Average Increase 4.82% Increase trend except in 2001 due to Forest health and economic index Forest Health vitality Year Year Economic Viability Of Forest Social & Environmental Benefits of Forest

19 2. Trend by three Components Average Increase rate : Health 8.1%, Economics 1.4%, Social & Env. 3.8% Fores t Health and vitality Fores t Economis Viability Social and Environmental Benfits

20 3. Local Government Level : Efforts Evaluation To induce local governments to make more efforts in implementing SFM, and efforts evaluation was conducted. Applied moving average method to efforts evaluation for the recent three years, and weight s are differently applied so that the recent increase or decrease can be considered more important

21 V. Usage of FSI and Recommendaion Forest Sustainability Index can assist the nation and local government in making data-driven planning, better program, and program decisions for SFM Forest SFI Sustainability Index Formulating forest Policy Evaluation the process of SFM Allocating budget Promoting Public Awareness

22 Assist the nation and local governance in making data-driven planning & better policy and program decisions for sustainable forest management C &I of the FSI is required to correspond with those of the Montreal Process, where member countries provide national reports for sustainable forest management every five years Conditions & trends of forest be more objectively evaluated through improved understanding of social, economic & environmental conditions of forest, & development of specific goals for each indicator Forest Sustainability Index needs to be refined to represent site-level conditions, and to provide a local level framework for developing policies and plans
