“…Hence, the imageries were processed with Envi 4.5 to create a multispectral and supervised classification for land coverage. Supervised image classification was performed by using the Maximum likelihood algorithm as one of the popular techniques of this process (Osunmadewa et al 2018;Kumar et al 2021). The accuracy test applied through the Kappa coefficient was conducted using a confusion or error matrix to compare the relationship between known field data and the classification results.…”

Abstract. Dimara PA, Purwanto RH, Sunarta S, Wardhana W. 2021. The spatial distribution of sago palm landscape Sentani watershed in Jayapura District, Papua Province, Indonesia. Biodiversitas 22: 3811-3820. Sago palm is one of the starch sources used as local food in Papua, therefore this research aims to identify the supporting environment for the plant to grow by utilizing spatial data. The methods used were Spatial Analysis and Field Survey, where the first employed satellite imagery of Quickbird in 2012 and Landsat 8 in 2020 to distinguish between sago and non-sago palm landscape. In the process, five parameters were used, consisting of covering land elevation, slope gradient, soil type, rainfall as well as the optimal distance from the river and lake. The result showed the sago palm landscape in Sentani Watershed lies in the elevation of 0-450 m asl, while its largest habitat which lies between 0-100 m asl covering an area of 4,385.63 is found in a flat slope covering an area of 2,941.99 ha and in a very steep slope that spreads out over 41.92 ha. Generally, in Sentani Watershed, the plant grows in Mediterranean soil possessing thick solum with pH 5.0-7.0 and medium to great soil erodibility. Moreover, the largest habitat experiences a precipitation rate of 1,750 mm yr-1 covering a total of 6,846.24 ha, while the Doyo River has the largest sago palm landscape compared to other rivers.

“…Ketika merencanakan pengembangan pertanian berbasis lahan, perhatian harus diberikan pada keadaan sumber daya lahan dan kemampuannya untuk mencapai keberlanjutan (Setyanto, 2014;Pratama et al, 2016;Kumar et al, 2021). Tata guna lahan yang mengabaikan kelas kesesuaian lahan dan lingkungan menyebabkan kerusakan lingkungan yang serius dan tidak berkelanjutan (Zhu et al, 2022).…”

Pertambahan penduduk sejatinya harus juga dibarengi dengan pertambahan jumlah produksi untuk menjaga agar kebutuhan pangan masyarakat tetap terjaga. Penelitian ini dilaksanakan dengan maksud untuk mengevaluasi kesesuaian lahan serta menentukan alternatif perencanaan penggunaan lahan untuk pengembangan tanaman jagung, ubi kayu dan kacang tanah di Kecamatan Poleang Timur. Penelitian ini menggunakan metode survei bebas didasarkan pada unit lahan. Prosedur pelaksanaan survei tanah dilaksanakan dalam beberapa tahap meliputi tahap persiapan, tahap operasi lapangan dan tahap analisis sampel di laboratorium. Perencanaan penggunaan lahan dilakukan berdasarkan evaluasi kemampuan lahan dan besarnya bahaya erosi. Hasil penelitian menunjukkan bahwa pengembangan tanaman pangan di Kecamatan Poleang Timur Kabupaten Bombana sesuai untuk dikembangkan khususnya jagung seluas 5271,29 ha (78,04%), ubi kayu seluas 4872,34 ha (72,14%) dan kacang tanah seluas 5020,77 ha (74,33%). Alternatif arahan pengelolaan lahan untuk pengembangan tanaman pangan khususnya jagung, ubi kayu dan kacang tanah di Kecamatan Poleang Timur Kabupaten Bombana dilakukan pada tingkat sedang berupa pemupukan untuk faktor penghambat ketersediaan hara, penambahan bahan organik dan pengapuran untuk perbaikan faktor penghambat retensi hara, bahaya erosi diatasi dengan usaha konservasi tanah seperti penanaman sesuai kontur, pembuatan teras dan penanaman tanaman penutup tanah, pembuatan saluran irigasi/pengairan untuk penghambat ketersediaan air. Diharapkan dengan adanya penelitian ini mampu memberikan sumbangsih pemikiran dan sebagai bahan pertimbangan untuk pemerintah daerah setempat dalam hal penyusunan kebijakan serta untuk masyarakat dalam usaha pengembangan tanaman pangan.

“…Studies on LUCC evolution mechanisms largely include long-term historical evolution characteristic analysis [14,15] and future evolution simulation [16][17][18]. Based on quantitative analysis of land-use change rate, dynamic degree, and other indicators [19,20], the focus has been on remote sensing image interpretation and GIS spatial analysis. Obtaining the dynamic evolution and spatial difference of spatial patterns [21,22] and using FRAGSTATS software to calculate the landscape pattern index to describe landscape evolution is also an important part [22][23][24].…”

The Belt and Road Initiative (BRI) has revealed that it is necessary to strengthen research on land use and land cover change (LUCC) and ecological risk in key regions of countries around the world. In this study, the spatiotemporal characteristics of LUCC in the five capitals of Central Asian countries within the BRI were analyzed. Based on the grid scale, a landscape pattern index was introduced to quantitatively evaluate the landscape ecological risk levels of the five capitals. The results showed the following: first, the components of land use types in the five capitals have different structural characteristics, which are mainly grassland, unused land, and cultivated land. The landscape types that changed significantly were water and unused land, while the construction land area showed a trend of continuous increase. Second, different capitals have different land-use transfer patterns. Akmola State is mainly converted from cultivated land to grassland; Chuy State is mainly converted from forest land to grassland; Dushanbe and Tashkent City are mainly converted from grassland to forestland; and Ahal State is mainly converted from grassland to unused land. Third, the overall landscape ecological risks of the five capitals were low. Akmola State had the largest proportion of lowest ecological risk areas, whereas Chuy State and Dushanbe City had an increasing trend of highest ecological risk areas. The level of ecological risk in Tashkent remained stable during the study period, and the highest ecological risk areas in Ahal State decreased to 49,227.86 km2. This study has enriched the research results of land use change and landscape ecological risk assessment of countries within the BRI and can provide a research reference for these countries and regions to achieve ecological sustainable development and strengthen ecosystem management.
