    The results from the FRA 2000 Remote Sensing Survey cover most of pan-tropical forests under a wide range of ecological conditions, from tropical rainforests to dry forests. Estimates were calculated at different levels: at sampling unit, stratum, sub-regional, regional, pan-tropical levels and at ecological zones level. The reliability of the estimates differs according to the study level. The survey was mainly designed for generating information with an acceptable statistical precision at the regional and pan-tropical levels. Estimates at the subregional level have a relatively low precision but give valuable indications on forest changes processes.

    The FRA 2000 estimates of forest area and change are largely based on national statistics and inventory reports, which contain detailed information on the forests of individual countries. However, differences among data sets from the various countries can be great owing to the methods applied, the terms and definitions employed and the currency of the information in the individual inventories. Despite adjustments made to accommodate these differences, uncertainties can still arise when statistic s from different countries are compared, especially those relating to forest change.

    Forest Resource Assessment 2000 (FRA 2000), a priority program within the FAO Forestry Department, is executed at the request of all FAO member countries. FRA 2000 is based on country-level information from national inventories, research projects, national consultations and various studies that provide information on forest cover, volume and change over time. FRA 2000 conducted two pilot studies on forest cover change (positive and negative) in Nepal and Guatemala. Country selection was based on the importance of the forestry sector in the development process of each country. The Guatemala case study was developed in co-operation with national and international institutions that provided the best available information regarding the major factors, situations and processes that have an impact on forest and land cover change (deforestation, reforestation, afforestation, degradation).
