Profile, Level of Vulnerability and Spatial Pattern of Deforestation in Sulawesi Period of 1990 to 2018

Abstract

Deforestation is an event of loss of forest cover to another cover. Sulawesi forests have the potential to be deforested as with Sumatra and Kalimantan. This study aims to provide information on deforestation events in Sulawesi from 1990 to 2018. The data used in this study are (1) land cover in 1990, 2000, 2010; (2) Landsat 8 imagery in 2018; (3) administrative map of BIG in 2018. The methods used are (1) image classification with on-screen digitation techniques following the PPIK land cover classification guidelines, Forestry Planning Agency (2008) using ArcGIS Desktop 10.6 from ESRI; (2) overlapping maps; (3) analysis of deforestation; (4) analysis of deforestation profiles, (5) vulnerability analysis; and (6) analysis of distribution patterns of deforestation. The results showed that the profile of deforestation occurring on Sulawesi Island in the 1990–2018 observation period was dominated by profile 3-1-1 (the proportion of large forest area, the highest incidence of deforestation early stage at the beginning, at a low rate) in 13 districts. The level of vulnerability to deforestation is a non-vulnerable category (37 districts) which is directed to become a priority in handling deforestation in Sulawesi. Spatial patterns of the deforestation that occurred randomly and were scattered are dominated by shrubs, dryland agricultural activities, and small-scale plantations.

Habitat preferences of wild orchids in Bantimurung Bulusaraung National Park to model their suitable habitat in South Sulawesi, Indonesia

“…Deforestation is the most prevalent threat for orchids (Jalal 2019;Li et al 2018), moreover in Indonesia (Budiharta et al 2011). Generally, Sulawesi experiences an early stage of large-scale deforestation (Rijal et al 2019a). From 2001-2020, South Sulawesi alone lost 318 Kha of tree cover, emitting 196Mt of CO2 with Luwu Timur District having the most tree cover loss at 92.4 Kha compared to a provincial average of 13.2 Kha (Global Forest Watch 2021b).…”

“…Indonesia, for example, has lost 27.7 Mha of tree cover from 2001 to 2020 and released 19.0Gt of CO2 emissions, with the top contributors being Riau, West Kalimantan, Central Kalimantan, East Kalimantan, and South Sumatera provinces (Hansen et al 2013;Global Forest Watch 2021a). In Sulawesi, forest cover declined in the period of 1990-2018 with the largest forest cover loss was in North Sulawesi (23.29%) and the smallest occurred in South Sulawesi (13.57%) (Rijal et al 2019a). Forest degradation makes orchids vulnerable to habitat fragmentation and modification (Jalal and Singh 201;Reina-Rodriguez et al 2017).…”

Pengembangan Agroforestry Kopi dalam Mendukung Peran Hutan di Kawasan Highland Kabupaten Jeneponto

“…Salah satu penggunaan lahan yang dapat dikonversi adalah hutan, sehingga akan berdampak juga kepada aspek ekologis (Samsuri et al, 2014). Laju deforestasi di Pulau Sulawesi dibawah 2 persen pada kurun waktu 1990 sampai 2018 (Rijal et al, 2019).Hal tersebut lebih lebih tinggi dibanding dengan rata-rata deforestasi negara-negara Asia Tenggara yang berada pada angka 1 % periode 1990-2000 dan 0.4% dalam kurun waktu 2000-2010 (Sulistiyono et al, 2015).…”

Study on Spatiotemporal Characteristic and Mechanism of Forest Loss in Urban Agglomeration in the Middle Reaches of the Yangtze River

“…Unplanned logging, deforestation, and reclamation are particularly problematic, causing permanent forest loss with significant persistence and spatial randomness [13][14][15][16]. Additionally, while planned logging (e.g., transforming natural forests into oil palm forests or timber forests) may stop significant net forest loss, it diminishes the forest's ecological value and degrades many of its ecosystem services [17][18][19][20]. Among regions with extensive and highly developed heavy industries and mining activities, environmental pollution (e.g., soil and water pollution) can lead to significant permanent forest loss [21,22].…”
