Jember is surrounded and limited by highlands such as Mount Argopura, Mount Ijen, Mount Argopura, and the southern karst mountains. In 2015-2022, the Jember area flooded during the rainy season and dried during the dry season. Changes in land cover that do not follow the science of soil preservation will cause disasters, including landslides and erosion. The purpose of this study is to assess the risk of landslides on the slopes of Mount Argopura through the Geographic Information System. The study used a field survey method that was divided into several stages, including making a working map, conducting a field survey, and analyzing the data in the laboratory. The sensitivity analysis of the landslide level used as the basis for the assessment used the relationship between the parameters of soil erodibility, soil erosion, slope and soil conservation, and slope length. The sensitivity of the level of landslide risk on Mount Argopura is divided into five classes, from very light to very heavy. The very light category covers 4.92% of the total area with erosion of 0.47 t/ha/year. The very heavy class covers 39.70% of the total area, with 1,360.79 t/ha/year erosion.

“…As per Prasannakumar et al (2011), the average erosion rate for the Siruvani river watershed in Attapady valley, Kerala, India, is 14.917 t.ha -1 .yr -1 , with 5.76% (1,184 hectares) of the land lying under the severe soil erosion zone and 11.50% being under the high-erosion zone. A study by Tufekcioglu et al (2018) in the Coruh River Basin of Turkey found that the Velikoy sub-watershed had an average surface soil loss rate of 3.9 t ha-1 yr-1, with 8.2% of the area at high or very high risk for potential erosion. Another study by Sheikh et al (2011) observed that mean soil erosion rate of 12.2 t.ha -1 .yr -1 at the Upper South Koel Basin, Jharkhand, India.…”

Among many environmental problems, soil erosion poses a serious threat to the region known as Chittagong Hill Tracts (CHTs) in Bangladesh, comprising three districts, namely Bandarban, Rangamati, and Khagrachari. The annual soil erosion rate for this hilly terrain was calculated using the Revised Universal Soil Loss Equation (RUSLE) model integrated with Remote Sensing and Geographic Information System (GIS). The ranges of the estimated erosivity of rainfall, erodibility of the soil, slope length and slope steepness, crop management factor and conservation practices are 806.2 to 1513.2 MJ.mm.ha-1.h-1.yr-1 (or an average of 1121.5 MJ.mm.ha-1.h-1.yr-1), 0 to 0.02 t.h.MJ-1 mm-1, 0 to 78.8 (or average 0.41), 0 to 0.63 (or average 0.57) and 0.55 to 1 (or average 0.73), respectively. As per the findings, the study area is expected to lose 182621.5 tons of soil annually, with the estimated annual soil erosion rate of 15.18 t.ha-1.yr-1 also predicted. The weighted overlay index approach was used to produce the probability zone map, which shows that the majority of the research region falls within the slight probability zone and that only a small percentage falls inside the high and very high probability zones. This study proves RS-GIS is useful for predicting erosion and can be used in soil conservation programs.

Toprak erozyonu doğal kaynakların sürdürebilirliğini, sosyal ve ekonomik gelişmeyi, karasal ve sucul ekosistemi tehdit eden dünya çapında çevresel bir sorundur. Ülkemizde insanların doğal kaynaklar üzerine baskısının artmasıyla erozyon miktarı artmış ve yaşamsal ekosistem üzerinde olumsuz etkilere neden olmuştur. Meydana gelen bu etkiyi azaltmaya yönelik önlemler alınabilmesi için bir havzada toprak kaybı miktarının belirlenmesi gerekmektedir. Çalışma alanı, Türkiye’nin Doğu Karadeniz Bölgesinde Trabzon ili sınırları içerisinde yer alan Değirmendere Çatak alt havzası seçilmiştir. Çalışmada toprak erozyonu miktarının hesaplanmasında Evrensel Toprak Kaybı Denklemi (RUSLE) ve Coğrafi Bilgi Sistemleri (CBS) kullanılmıştır. Çalışma sonucunda, ortalama R, K, LS ve C değişken değerleri sırasıyla 324.65 MJ ha-1 mm saat-1 yıl-1, 0.029 t ha saat ha-1 MJ-1 mm-1, 11.23 ve 0.038 olarak belirlenmiştir. Bu verilere göre, Çatak alt havzasında yıllık ortalama toprak kaybı 3,28 ton/ha/yıl, sediment iletim oranı (SİO) 0.44 ve sediment verimi 1.46 ton/ha/yıl olarak bulunmuştur. Çalışma sonucunda elde edilen veriler erozyon kontrol çalışmalarında toprak ve su koruma planlamaları için altlık teşkil edecek ve uygulayıcılara yol gösterici niteliktedir.
