Description |
This study aimed to assess the level of vulnerability of water resources on the climate variability of Aesesa Watershed, NTT Province. Vulnerability assessments using IPCC concept, where the vulnerability as a function of exposure, sensitivity and adaptive capacity. Criteria and indicators of those function were obtained from previous studies, then given a score and weighting in accordance with the degree of importance, spatially display and overlay, to produce vulnerability map. The results showed that the trend of annual temperature in the upper watershed in recent years is decreased, while in the middle and lower areas are increased. The annual precipitation showed an trend in the , while in the middle and showed a declining trend. increasing upper area lower areas Related to water resources, the river's stream flows are relatively stable in the last five years. Water quality assessment in the river is categorized as lightly polluted in the upstream and moderately polluted in the downstream. Based on vulnerability map, the watershed is classified into highly vulnerable (54%), moderately vulnerable (13%) and lowly vulnerable (33%). Such results could be useful for the Watershed Authority and other stakeholders to establish strategies, plans and actions for addressing problems on vulnerability of water resource.
Kajian ini bertujuan untuk mengetahui tingkat kerentanan sumber daya air terhadap variabilitas iklim di DAS Aesesa Provinsi NTT. Penaksiran kerentanan menggunakan konsep IPCC, dimana kerentanan merupakan fungsi dari keterpaparan, sensitivitas dan kapasitas adaptif. Kriteria dan indikator keterpaparan, sensitivitasdan kapasitas adaptif didapatkan dari kajian terdahulu. Kriteria dan indikator kemudian diberikan skor dan bobot sesuai derajat kepentingannya dan disajikan secara spasial serta dilakukan overlay untuk mendapatkan peta kerentanan. Hasil menunjukkan bahwa tren suhu tahunan di hulu DAS dalam beberapa tahun terakhir mengalami penurunan, sedangkan di bagian hilir mengalami kenaikan. Sementara indikator curah hujan tahunan, di daerah hulu DAS menunjukkan tren kenaikan, sedangkan di daerah tengah dan hilir tren menurun.Terkait dengan kuantitas air, Sungai Aesesa, sungai utama di DAS Aesesa mempunyai debit yang relatif sama selama lima tahun terakhir. Kualitas air di Sungai Aesesa dikategorikan cemar ringan di hulu dan cemar sedang di hilir dalam beberapa tahun terakhir . Peta kerentanan menunjukkan bahwa sekitar 54% wilayah DAS memiliki tingkat kerentanan tinggi, 13% diklasifikasikan ke tingkat kerentanan sedang dan 33% dikategorikan ke tingkat kerentanan rendah. Hasil kajian ini bisa bermanfaat bagi pengelola DAS, atau pemangku kepentingan lainnya untuk menyusun strategi, rencana dan aksi dalam menanggulangi masalah kerentanan sumber daya air. |
