It is hoped that this approach will lead for further capacity building in countries (FRA 2000 –main report). While countries firmly support this approach, it has sometimes been criticised on the basis that country information may be inaccurate, incomplete, out-of-date, or internationally inconsistent (Stokstad, 2001; Czaplewski, 2002). According to the FRA 20 00 main report, many countries still lack reliable primary information at the national level. Some examples of country level changes in FRA 1990 and FRA 2000, as well as reliability assessment of TBFRA 2000, support this concern. One goal of the future assessments will be to further strengthen country capabilities and participation. In this way, FAO intends to improve the information quality as well as to assist developing countries in their inventories. FAO should also work towards reducing the interval between successive assessments, or towards the establishment of continuous regional assessments. FAO conducted a remote sensing study of tropical forests in FRA 2000 for assessing the area changes between 1980-1990 and 1990-2000. Stratified sampling with a sampling ratio of 10 % was applied. The purpose was to independently evaluate the data quality of country information and to improve FAO’s understanding of land-cover change processes in the tropics, especially deforestation, degrada tion, fragmentation and shifting cultivation, among others. FAO also plans to continue to use country information and independent remote sensing surveys in future assessments, but also to emphasise field observations as a means of gathering broad and representative information.
