4. Transforming data into information
Modeling land-use change includes the following processes: Demography; Technology; Economy; Political and social institutions; Culturally determined attitudes, beliefs, and behavior; Information and its flow. �Furthermore, missing connections might arise if potentially effective institutions exist at the appropriate scales but decisionmaking linkages between scales are ineffective. Decisions also might be based on information aggregated at an inappropriate scale, even though it may exist at the appropriate scale (Cleveland et al. 1996). An example of the latter is the biennial national forest cover analysis prepared by the Forest Survey of India. While forest cover is assessed at the level of small local units, it is aggregated and reported at the district level, which is a larger administrative unit, rather than at the watershed based forest division level, at which forests are managed.� Open source systems are discussed.
FORIS includes both existing source information and derived information. All distributed information should be verified, meaning that all data items should have a source reference, and the data processing should be transparent. The countries validate and approve information concerning their country before publication. Data ownership is distributed among users. Security should be tight. Integration with other system development efforts is essential. The administration of geographic units is a known obstacle when producing FAO reports. Countries change name, split, merge or simply should not be shown. Furthermore, they can be grouped in different ways depending on the purpose of the report. Finally, countries are subdivided into administrative units, or into other arbitrary units based on e.g. climatic conditions.
The 1990 FRA used a set of models to predict forest change as a function of population, based on the assumption that �the growth of human population, independently in the absence of economic development, and jointly with poorly planned and uncontrolled economic development, are the driving forces behind human activities that initiate deforestation�. FAO makes and keeps current a metadatabase describing what data exist throughout the tropical world, as well as archiving the actual data in the FORIS database. Models to derive forest change as a function of other attributes, providing a platform for generating estimates for all countries regardless of availability of country level data. Synthesis based on partial data plus expert opinion is used to arrive at answers. The Delphi Technique and Convergence of Evidence method are both used. A small group of experts can weigh the different available data sources for each country and attempt to arrive at final estimates. Explanation of the decision process and documentation of the weights assigned is essential. This is followed by critiquing by other experts and attempting to seek some consensus on final estimates.
Discusses the FAO Forest Resource Assessment �documentation room�
The information related aspects of Agenda 21.
Harmonization is the process of making reports to different instruments comparable, for example through the use of common or comparable terms and definitions, standardized units for data and common reference years. Streamlining refers to the reduction of the number of reports or the amount of information required in individual reports; this is made possible by harmonizing information among reports or reducing duplication in the reporting requests. Ten international instruments that are in force are particularly relevant to forests are discussed. Analysis shows that the information requested by most of the instruments relates to action taken to implement commitments under the instrument, is descriptive in nature, and is focused on measures taken in policy, legislation, capacity building, financing or other means of implementation. Only a few instruments require parties to provide quantitative information related to forests or forest resources. The burden on countries to fulfill international reporting requirements has been noted throughout the UN system.
Global forest assessments provide information on development, changes or progress in forests and forestry required for decision-making by international fora and by countries. For this purpose it is not enough to quantify forest resources; assessments increasingly aim to address all benefits from forests - i.e. the use of the resources. Global forest assessments are largely made by aggregating and standardizing national information. This approach is necessary because practically all forest information is compiled at the national level through country-led initiatives. Forest information provided by countries needs to be scrutinized carefully by a neutral organization, because it is often political. Much interest has recently been attached to changes in forest area. The reported forest condition depends highly on the national policy context. In the absence of neutral and systematic facts, forest information has become politicized. At present forest information is requested by many international organizations and instruments in an uncoordinated way. There is a need to ensure that the information requested at the international level can realistically be supplied by countries. In this context also it is necessary to strengthen capacity at the national level.
The demand for forest information has changed dramatically over the past eight years since forest policy underwent a shift in perspective from timber production to social, economic and environmental issues. While the past forest policies focused only on annual roundwood statistics to promote sustainable commercial forestry development, the current forest policy endeavours to promote sustainable forest management for all forest types. This change in policy perspective has necessitated the need to integrate policy development and implementation with the information gathering process. A collaborative network supported by incentives to providers of information is required for the successful implementation of this process. Users of information often fail to take into consideration the constraints faced by institutions that provide information. To ensure a systematic flow of information from the local to the international level, data categories need to be communicated to relevant spheres of government prior to the reporting period. Finally, a system that has the capacity to draw and coordinate the relevant information from different sources is required.
The success of a European Forest Information System will depend on the degree to which the information needs of potential users will be satisfied. Thus the demand as well as the supply side of information have to be taken into account in the scope of this study. Information to be provided by a forest information system varies according to the purpose and the scale for which it is used. Information needs which are task specific require a set of attributes with large thematic and spatial degree of detail. Information used for example for forest management purposes requires data on the compartment and sub-compartment level (e.g. standing timber volume by species and assortment classes for each stand). Information needed on the strategic and integrative level has to be aggregated in both thematic and spatial terms. For each attribute the information needs had to be assessed within the three information groups �production�, �environmental aspects� and �land use�.
