Sustainable management of natural forests has been a worldwide issue after the United Nation’s Convention on Environment and Development held in June 1992. Forest certification is a process to determine whether a forest is sustainably managed or not. For this purpose, certain principles, criteria and indicators are used. Many organizations are involved in development of such principle, criteria and indicators at national and international level. In this context, Indonesia has developed its own principle, criteria, indicators, verifiers and verification methods. Indonesian Ecolabelling Institute (LEI) is responsible for that work using CIFOR system as a base. The criteria and indicators used in this research are from the system developed by LEI. Sustainable forest management is “the process of managing forest to achieve one or more clearly specified objectives with regard to the provision of a continuous flow of desired forest products and services, without undue reduction of its inherent values and future productivity and without undue undesirable effects on the physical and social environment. This means that, to make a forest management system sustainable it should be economically viable, environmentally sound and socially acceptable. This paper focused on some selected criteria, indicators and verifiers of production function of the tropical forest.
The objective of this study was to assess the land cover change in tropical rain forest using Landsat TM images within a specific period of time and categorize the change on the intensity scale of indicators for SNPFM. Those chosen indicators were assessed in Labanan forest management unit. Landsat TM images of 1996 and 2000 were used to assess the extent of change in forest cover. Data were analyzed to categorize the status of the assessed indicators on intensity scale for sustainable natural production forest management (SNPFM).
The study concluded that 1425 ha of forest cover, which is 1.71% of total Forest Management Unit (FMU) area, have been changed to other land cover types within the period 1996-2000 in the study area. But this change has not compelled the FMU to change its planned objectives. Thus, the indicator related to the forest cover change is categorized as “Fair” on the intensity scale of indicators for SNPFM
