“…Marine and coastal fishing constitutes one of the major livelihood activities, according to the significant increase in dependency on mangroves (22%) and coastal areas (18%) for livelihood (Table S2). All these changes together resulted in forest degradation, soil erosion, and sedimentation of streams and low‐lying areas, which further aggravated drainage congestion in coastal areas in addition to elevating levels of pesticide residues in soils (Abera et al, 2020; Murugan, Swarnam, & Gnanasambandan, 2013). Similar changes in socioeconomic activities were also reported from Thailand (Willroth, Massmann, Wehrhahn, & Diez, 2012), Sri Lanka (Jayasekara et al, 2018), Indonesia (Susanti et al, 2019), and Malaysia (Khosrokhani & Pradhan, 2014).…”

Post‐tsunami land degradation on a South Asian island: Implications for conservation priorities

In recent decades, land degradation has accelerated due to an increase in unsustainable human activities. In a case‐study of the Andaman Islands, located in the South Asian region, changes in land degradation types, soil erosion, and the effect of conservation measures for pre‐ (2000) and post‐2004 tsunami periods (2006, 2019) were recorded using temporal remote sensing data (LANDSAT, RESOURCESAT, CARTOSAT), field observations and a GIS‐based revised universal soil loss equation (RUSLE). The results showed that erosion, leaching, acidification, salinization, and drainage congestion were the major land degradation processes that could be traced to post‐tsunami human activities (R2 = 0.634). The study revealed significant forest cover loss during 2006–2019 (3.76%) compared to 2000–2006 (0.61%), while it revealed increased areas under settlement (14 km2) and mining (22 km2). The annual crop area exhibited a 0.42% loss, whereas the plantation crop area increased by 0.46%, indicating the abandonment of annual crops that resulted in an increased fallow area (21 km2) during the post‐tsunami period. As a consequence, degraded land increased by 2.5% of the total geographical area which was affaected by water erosion (2.3%) and chemical degradation (0.25%). The average erosion rate varied from 0.7 to 108 t ha−1yr−1 in 2000 but increased by 47% during the post‐tsunami period due to mining, settlement, and vegetable cultivation on slopes, as indicated by high cover management, support practice, and slope length factors. Practicing suitable conservation measures can provide a conservation benefit of 105,560 t yr−1 and a reduction in other forms of degradation without compromising the food production area.

“…Yulipriyanto (2010) mengatakan penggunaan pestisida yang berlebihan secara nyata berpengaruh pada organisme non target (bukan sasaran) cenderung mereduksi kompleksitas biologi tanah. Hasil penelitian Murugan et al (2013) menunjukkan bahwa total residu pestisida di tanah bervariasi dari 181.2 sampai 350.6 ppm telah mempengaruhi populasi Actinomycetes 32% bila dibandingkan dengan tanah tanpa residu. Selanjutnya hasil penelitian Supreeth et al (2016) menunjukkan bahwa pestisida Clorpirifos yang diberikan pada tanah subur yang tidak memiliki riwayat penerapan pestisida dengan 100 dan 200 μg g -1 diinkubasi selama 1, 7, dan 14 hari menunjukkan penurunan jumlah unit pembentuk spora jamur.…”

Dampak Residu Pestisida Terhadap Keanekaragaman Jamur Tanah Pada Lahan Sayuran

2020

Pestisida memiliki efek negatif pada organisme tanah sebab mengandung senyawa beracun yang berbahaya. Penggunaan pestida oleh petani desa Noelbaki dalam budidaya sayuran cukup intensif dengan frekuensi penyemprotan 2-3 kali perminggu dengan masa tanam yang berlangsung terus-menerus sehingga memberikan dampak negatif terhadap lingkungan tanah. Tujuan penelitian ini adalah untuk mengetahui kandungan residu pestisida dan keanekaragaman komunitas biota tanah pada lahan sayuran yang diaplikasi pestisida dan tanpa pestisida. Metode penelitian yang digunakan adalah metode survey. Pengambilan sampel tanah dilakukan secara diagonal. Pengambilan sampel tanah bukan komposit dilakukan untuk pengamatan mikroba tanah, sedangkan komposit untuk analisis sifat fisika kimia tanah. Variabel yang diamati adalah kandungan residu pestisida, kepadatan populasi, keanekaragaman dan frekuensi kehadiran, jamur tanah serta sifat fisika kimia tanah pada lahan sayuran Vertisol dan Inceptisol yang diaplikasi pestisida dan tanpa pestisida. Analisis residu pestisida dilakukan dengan metode GC/MS, dan perhitungan jumlah mikroba dilakukan dengan metode Plate Counting Agar (PCA), sedangkan identifikasi mikroba dilakukan dengan pengamatan secara mikroskopis dan makroskopis. Residu pestisida berbahan aktif Lamda-cihalotrin pada contoh tanah jenis Vertisol yang diberi pestisida sebesar 0,060 ppm, dan pada contoh tanah Inceptisol dengan berbahan aktif Dimetoat sebanyak 0,042 ppm. Kepadatan populasi jamur tanah lebih tinggi pada lahan sayuran tanpa aplikasi pestisida sebanyak 71,6 cfu g-1, nilai indeks keanekaragaman jamur tanah lebih tinggi pada lahan sayuran aplikasi pestisida 1,609, frekuensi kehadiran spesies jamur Penicillium konstansi 100 % dan Mucor 90 %.

Application of Chlorpyrifos on agricultural fields to protect crops against pests results in accumulation of it in soil and other environmental samples. The insecticide transform into 3,5,6-Trichloro-2-Pyridinol (TCP) through hydrolysis in soil, which has got antimicrobial property and hence resists its degradation in natural condition. In the current findings, a bacterial isolate capable of mineralizing Chlorpyrifos without accumulation of TCP was isolated from agricultural soil by enrichment method. Based on Morphological, Biochemical Characterization and with Bergey’s Manual comparision, the isolate was identified as Staphylococcus sp. The isolate was found to metabolize chlorpyrifos completely in Mineral salt medium with chlorpyrifos as the sole carbon source. No metabolites of chlorpyrifos were detected in Liquid Chromatography-Mass Spectroscopy (LC-MS) analysis after 7 days of incubation. The novelty of the outcome of the experiment relies on Staphylococcus sp.ES-2 in complete mineralization of chlorpyrifos which can be used as a potential bioaugmenting agent in the chlorpyrifos contaminated sites.
