“…Pemahaman mengenai deforestasi dan faktor-faktor penyebabnya dapat membantu dalam perencanaan bentuk pengelolaan hutan untuk mewujudkan pengelolaan hutan yang lestari (Panta et al, 2008). Salah satu kajian deforetasi adalah pemodelan spasial, yaitu pembangunan sebuah model deforestasi dengan peubah-peubah yang berkaitan dengan faktor-faktor penyebab terjadinya deforestasi.…”

ABSTRAKHutan merupakan bagian dari ekosistem yang menyediakan jasa lingkungan bagi satu kesatuan ekosistem. Penurunan fungsi hutan dalam suatu ekosistem terjadi salah satunya karena deforestasi. Penelitian ini bertujuan membangun model spasial deforetasi di KPHP Poigar. Metode analisis deforestasi yaitu dengan analisis perubahan tutupan hutan menjadi tutupan bukan hutan dengan teknik post classification comparison. Analisis faktor penyebab deforestasi dilakukan dengan pembangunan model spasial deforestasi menggunakan model regresi logistik biner. Hasil penelitian menunjukkan bahwa luas penurunan tutupan hutan akibat deforestasi pada periode 2000 sampai 2013 yakni 12.668,2 hektare. Penyebab deforestasi di KPHP Poigar dipengaruhi oleh enam faktor yaitu jarak dari jalan, jarak dari pemukiman, jarak dari sungai, kepadatan penduduk, ketinggian tempat dan kemiringan lereng. Model regresi logistik dibangun menggunakan lima peubah penjelas yaitu jarak dari jalan, jarak dari sungai, kepadatan penduduk, ketinggian tempat dan kemiringan lereng. Kemampuan model dalam memprediksi deforestasi sebesar 58 % dari kejadian deforestasi aktual, sehingga model spasial deforestasi dapat menjadi salah satu sumber informasi untuk penyusunan arah pengelolaan KPHP Poigar kedepan.Kata kunci: Deforestasi, model regresi logistik, pemodelan spasial, KPHP Poigar ABSTRACT Forest is a part of the ecosystem that provides environmental services. Deforestation may decrease forest function in an ecosystem. This study aims to build a spatial model of deforestation in a forest management unit (FMU) of Poigar. Deforestation analysis carried out by analyze the change of forest cover into non-forest cover with post classification comparison technique. Driving forces of deforestation carried out by spatial modeling using binary logistic regression models (LRM). Result of logistic regression model was used to predict the deforestation in 2013 and

“…In the Himalayas, the application of remote sensing was introduced in the mid-1980s [24] to identify and analyze the Land Use Land Cover (LULC) pattern [25][26][27]. Through the analysis of the spatial and temporal patterns of deforestation and the identification of key variables related to deforestation, efforts are being made to identify the driving forces behind changes to forest cover [28][29][30][31][32].…”

Mapping Deforestation and Forest Degradation Patterns in Western Himalaya, Pakistan

et al. 2016

Abstract:The Himalayan mountain forest ecosystem has been degrading since the British ruled the area in the 1850s. Local understanding of the patterns and processes of degradation is desperately required to devise management strategies to halt this degradation and provide long-term sustainability. This work comprises a satellite image based study in combination with national expert validation to generate sub-district level statistics for forest cover over the Western Himalaya, Pakistan, which accounts for approximately 67% of the total forest cover of the country. The time series of forest cover maps (1990, 2000, 2010) reveal extensive deforestation in the area. Indeed, approximately 170,684 ha of forest has been lost, which amounts to 0.38% per year clear cut or severely degraded during the last 20 years. A significant increase in the rate of deforestation is observed in the second half of the study period, where much of the loss occurs at the western borders along with Afghanistan. The current study is the first systematic and comprehensive effort to map changes to forest cover in Northern Pakistan. Deforestation hotspots identified at the sub-district level provide important insight into deforestation patterns, which may facilitate the development of appropriate forest conservation and management strategies in the country.

Panta et al (2008) explained that the deforestation defi ned as a changing of forest cover to another land covers, meanwhile the degradation process needs a long process to become deforestation. According to Gilliba et al (2011), socio economic factors infl uencing deforestation in the Bereku Forest Reserve were livelihood activities, period of residence and distance to the forest.…”
