Landslides are a widespread natural hazard that threatens the built and natural environment and increases the areas of deforestation. Landslides have an impact on human life, the impact can be reduced by reducing the risk of landslides, reducing the risk of landslides aims to reduce the number of people affected, deaths and economic losses. Forests and vegetation can provide a protective function against landslides consisting of hydrological and soil conditions, such as soil moisture, water infiltration, and others. This ability of vegetation is called nature based solutions. The 46 studies selected for this landslide nature-based solution were analyzed with a focus on an in-depth literature review. The articles were analyzed with three focus reviews, namely: 1) types of landslides, 2) solutions regarding landslide mitigation, and 3) landslide risks. The types of landslides discussed in this article are 73% shallow landslide types, 22% landslide types rotation and 5% flow landslide type. The risk in this article regarding hazards/threats is discussed at 57%, exposure around 21% and vulnerability around 22%. Landslide risk reduction solutions in the articles reviewed, as many as 44% discussed nature-based solutions, 30% about other solutions, and 30% there were no solutions in reducing landslide risk. In the publication of 46 articles, nature-based solution approaches that are widely mentioned are environmental engineering, soil bioengineering and protected forests. The nature-based solution in this research shows that vegetation is the main solution in disaster mitigation measures.

“…Plot 11, which is located in a protected area, was also prone to landslide since there was land clearing for agriculture and is supported by soil and rock types. Steep (35º-45º) to very steep (45º-65º) slopes have a susceptibility to landslides (Amukti et al 2017). Loess plateau landslides occur mainly on sunken slopes that have an inclination angle of 20º-35º (Zhuang et al 2017).…”

Abstract. Nuryanti DM, Liana, Witno, Soma AS, Asrianny, Ayu SM, Awalia IM. 2023. Composition, diversity and association of pioneer plants on post-landslide areas in Palopo, South Sulawesi, Indonesia. Biodiversitas 24: 1862-1870. The existence of pioneer plants is very important because of their role in initiating vegetation succession as well as regulators of the physical properties of a disturbed environment. Landslide is one type of environmental disturbance that causes vegetation loss, either partially or entirely. In many cases, several pioneer plants start to appear following a landslide. This study aims to assess the vegetation composition, diversity and interspecific association of plant species in post-landslide areas in Palopo City, South Sulawesi, Indonesia. We employed sampling plot methods with a size of 5 x 5 m2 in 12 landslide sites with varying landslide characteristics during the period of 2021 to 2022. Vegetation composition was analyzed using Important Value Index and an interspecies association was analyzed using Chi-square analysis. The results of the study found that the pioneer plants on post-landslides consisted of a total of 112 species which can be classified into eight habitus, namely bamboo, herbaceous, vines, ferns, palms, shrubs, trees and bushes. Herbaceous plants had the largest number of species, with 53 species. Species with the highest IVI for tree was Trema orientalis (L.) Blume (79.86%), shrub was Homalanthus populifolius Graham (61.49%), bush was unidentified species (53.41%), fern was Nephrolepis cordifolia (L.) C.Presl (6.99%), vines was Merremia peltata (L.) Merr. (57.92%), herbaceous was Miconia papillosa (Desr.) Naudin (22.65%), while palm was Pandanus tectorius Parkinson ex Du Roi and bamboo was Bambusa balcoa Roxb. each had IVI of 200% because only one species was found. The results of the diversity analysis showed that trees, shrubs, bushes, ferns, vines and herbs had a moderate level of species diversity, while palm and bamboo had a low diversity level. Similarly, trees, shrubs, bushes, ferns, and vines had high evenness levels, while bamboo and palm had low evenness index. There were three associations between dominant plants, namely B. balcoa with T. orientalis, B. balcoa with H. populifolius, and B. balcoa with Macroptilium atropurpureum (DC.) Urb. The findings of this study suggest that in just one year, pioneer plants rapidly colonized post-landslide areas which provided vegetation cover for the open landscape.

Tanah longsor adalah bencana alam yang sering terjadi di Indonesia. Banyak faktor yang menyebab tanah longsor terjadi antara lain curah hujan yang tinggi, topografi yang curam, lapisan sedimen yang tebal dan pergerakan tanah. Salah satu daerah yang sering mengalami tanah longsor adalah Kecamatan Samigaluh. Oleh karena itu, pengambilan data mikrotremor dilakukan di Dusun Tegalsaari Desa Ngargosari Kecamatan Samigaluh Kabupaten Kulon Progo Daerah Istimewa Yogyakarta untuk mengetahui nilai frekuensi dominan dan amplifikasi di daerah tersebut yang diperoleh dari metode Horizontal to Vertical Spectral Ratio (HVSR). Selanjutnya, nilai frekuensi dominan dan amplifikasi diolah untuk mengetahui indeks kerentanan seismik, ketebalan lapisan sedimen, peak ground acceleration dan ground shear strain yang digunakan untuk mengetahui daerah yang berpotensi mengalami tanah longsor. Berdasarkan hasil analisis data mikrotremor diperoleh nilai frekuensi dominan antara 2,1 Hz – 18,7 Hz, nilai amplifikasi berkisar antara 1,4 sampai 8,1, indeks kerentanan seismik antara 0,27 – 26,04 s2/cm, nilai PGA berkisar antara 81,36 – 245,42 gal, ground shear strain antara 2,39 x 10-5 – 2,30 x 10-3 dan ketebalan sedimen berkisar antara 9,06 – 89, 55 meter. Daerah dengan potensi tanah longsor yang tinggi ditentukan dengan menganalisis persebaran nilai amplifikasi, indeks kerentanan seismik, ketebalan lapisan sedimen, peak ground acceleration, dan ground shear strain sehingga diperoleh daerah yang memiliki potensi tanah longsor tinggi berada di area 16, 46, 92, 100, 101, 103, 104, 105, 113, dan 114.
