Abstract

A land cover change from forest to non-forest is called deforestation. Deforestation that occurs is different in each region. The deforestation profile provides better information on deforestation that happened because it displays three aspects of the assessment, those are the Proportion of Forest Area to the Area (PLH) in each regency, the proportion of deforestation events (PKD) and the rate of deforestation (LD). This study aims to determine the profile of deforestation that occurred in West Nusa Tenggara and East Nusa Tenggara Provinces from 1990 to 2019. This study uses overlapping land cover and administrative data for forest-non-forest analysis. In addition, this study also uses forest area data which is then used to analyze deforestation that occurs inside and outside forest areas. The deforestation profile analysis produced 15 forms of deforestation profiles. The largest profile in West Nusa Tenggara Province is the 3-1-1 profile (large proportion of early events-low rate) which is the category of not vulnerable. The highest profile in the province of East Nusa Tenggara is 1-3-1 (small proportion-late-rate events) and is a very vulnerable category. Deforestation is dominant outside forest areas. The largest percentage of deforestation in forest areas in West Nusa Tenggara Province occurred in production forests amounting to 14.77% in the 2000-2010 period. Deforestation of East Nusa Tenggara in forest areas occurred in protected forests amounting to 13.65% in the 2010-2020 period.
