Abstract:
Deforestation is a global issue that attracts international community attention. This paper describes the behavior of deforestation of lowland tropical rain forests within the period of 2009-2015. The main objective of this research is to develop a typology of deforestation rates and identify trends in deforestation according to land conversion groups. To develop a behavioral typology of the deforestation rates, this study investigates whether the unit analysis of the sub-districts can be classified or grouped into some typology classes. From the analysis by considering the sub-district level as the smallest unit analysis, the study found that the rate of deforestation of lowland tropical rain forests in West Kalimantan Province is similar over the province, where the sub-districts could not be grouped according to the biophysical and socio-economic aspects. This research also finds that the trend of deforestation in the lowland tropical rain forests of West Kalimantan by land conversion group is: (1) unauthorized land conversion of 1,256,862.80 ha (65.28%); (2) semi-authorized land conversion of 308,247.14 ha (16.01%); and (3) authorized land conversion of 360,231.36 ha (18.71%). Unauthorized deforestation reached 65.28%. Therefore, it is necessary to increase the capacity of the community towards the authorized use of forests and increase supervision from the government.
