Perubahan iklim dapat meningkatkan peluang kejadian cuaca/iklim ekstrem. Salah satu dampak cuaca/iklim ekstrem adalah bencana hidrometeorologi, termasuk banjir. Banjir merupakan bencana paling banyak terjadi di Kalimantan Barat periode tahun 1998-2019. Salah satu faktor pemicu terjadinya banjir ialah hujan ekstrem. Durasi, intensitas, maupun frekuensi hujan ekstrem dapat diidentifikasi menggunakan Indeks Iklim Ekstrem (IIE) parameter hujan. Informasi terkait kecenderungan hujan ekstrem diperlukan untuk mendukung pembangunan berbagai sektor, terutama mitigasi bencana hidrometeorologi. Oleh sebab itu tujuan penelitian ini menganalisis kecenderungan hujan ekstrem berdasarkan delapan jenis nilai IIE di Kalimantan Barat. Data yang digunakan adalah data curah hujan harian periode tahun 1990-2019 pada 14 lokasi di Kalimantan Barat. Data curah hujan harian digunakan untuk menghitung nilai IIE menggunakan perangkat lunak RClimDex. Analisis kecenderungan menggunakan metode Uji Mann-Kendall, dengan tingkat kepercayaan ditentukan sebesar 95%. Hasil menunjukkan telah terjadi kecenderungan nilai IIE secara signifikan pada empat lokasi penelitian. Nilai Consecutive Dry Day (CDD) mengalami kecenderungan menurun di Bengkayang mengindikasikan hari kering cenderung terakumulasi pada suatu waktu yang relatif lebih singkat. Kemudian di Sekayam, Kabupaten Sanggau nilai CDD meningkat, namun Consecutive Wet Day menurun mengindikasikan periode jeda hujan semakin meningkat, namun hujan menjadi lebih lebat. Nilai Max 5-day precipitation amount meningkat di Sungai Raya, Kabupaten Kubu Raya terkait dengan perubahan tutupan lahan yang terjadi secara drastis. Nilai Annual total wet days precipitation dan Number of days above 50 mm di Karangan, Kabupaten Landak meningkat bersesuaian dengan kejadian banjir yang juga meningkat.

Critical land is a land whose soil condition has experienced or is in the process of physical, chemical, or biological damage which ultimately endangers hydrological, orological functions, and agricultural production. This research purposes were to determine the level of criticality of mangrove ecosystems, as the basis for sustainable management. Determination and delineation of the location were carried out photogrammetrically using Landsat 7 ETM + Band 542 imagery and maps, as well as terrestrial by direct measurement in the field. The species inventory and identification, tree/pole potency, saplings and seedlings used the line plot sampling and spot check methods. The results showed that the mangrove ecosystem area was of 577.07 ha, condition of dense (uncritical) vegetation reached an area of 138.16 ha (23.94%), followed by a rare (critical) condition of 286.63 ha (49.67%), while a damaged condition (very critical) 152.28 ha (26.39%). The dominant mangrove species were Sonneratia alba, Rhizophora apiculata, Avicenia marina, and Rhizophora mucronata. The main determinant of the mangrove ecosystems criticality was the mangrove cover area reduction as the non-mangrove land (ponds) impacts. To improve the quality of mangrove forest ecosystems, sustainable conservation is needed, one of which is the preparation of basic mangrove critical data and community empowerment. They are needed to restore, maintain and improve the function of forests and mangrove forest lands in order to increase their carrying capacity, productivity and their role in maintaining life support systems through rehabilitation programs.

Mapping forest fires became one of the efforts to reduce the fire vulnerability. Spatial model development for fire vulnerability could employ a GIS-based information value model (IVM) that excels in predicting vulnerability by leveraging hotspot inventory data. However, this model remained relatively unexplored. This research aimed to develop a fire vulnerability model of peatland-dominated areas in West Kalimantan Province and identify biogeophysical factors that significantly influence fire vulnerability in the research area. The IVM employed hotspots, accessibility, land cover, distance to settlements, distance to rivers, soil types, peat types, and Normalized Difference Vegetation Index (NDVI) parameters. The results revealed that the medium hazard class dominated forest and land fire vulnerability in West Kalimantan Province (272,663 ha). In addition, the average annual hotspot intensity from 2012 to 2022 negatively correlated with annual rainfall. Factors such as the brackish water topogen peat type, podzolic-cambisol soil type, accessibility, shrub land cover, and NDVI collectively contributed to the high level of vulnerability.
