“…Kebutuhan terhadap air yang semakin meningkat seiring dengan pertumbuhan jumlah penduduk tidak diimbangi dengan pemerataan akses air. Tekanan terhadap keterbatasan sumber daya air ini juga ditekan dari pengembangan sosial ekonomi, perubahan iklim, dan kemajuan infrastruktur [5] [6]. Penelitian ini memfokuskan pada kondisi kekeringan, dimana secara klimatologis merupakan kondisi tanpa air hujan yang cukup, dan secara hidrologi/pertanian/sosial-ekonomi merupakan masa kelangkaan air [7].…”

Peningkatan kebutuhan air dapat memicu permasalahan karena jumlahnya terbatas. Meningkatnya jumlah lahan terbangun untuk memenuhi kebutuhan manusia juga tidak membantu dalam menampung air. Akibatnya selain kurangnya akses air minum maupun air bersih, pada tingkat yang lebih parah dapat berupa kekeringan.Kekeringan adalah masa tanpa air hujan yang cukup atau masa kelangkaan air (Grigg, 1996 dalam Kodoatie & Sjarief, 2008). Daya dukung air menjadi penting karena merupakan kemampuan wilayah dalam mendukung kebutuhan air berdasarkan potensi ketersediaannya. Namun demikian, apakah hal ini relevan dengan kekeringan yang merupakan kondisi ketiadaan air? Penelitian ini mencoba mengetahui keterkaitan antara daya dukung air terhadap kekeringan. Metode yang digunakan adalah metode korelasi serta diagram kartesius. Hasil penelitian diketahui bahwa terdapat wilayah yang memiliki daya dukung air tinggi namun tingkat risiko kekeringan tinggi, maupun daya dukung air rendah namun risiko kekeringan rendah. Hal ini tidak relevan karena seharusnya apabila daya dukung air tinggi maka tingkat risiko rendah, ataupun sebaliknya. Dengan demikian dapat disimpulkan bahwa, daya dukung air tidak serta merta menjadi faktor determinan pada kekeringan, dan mungkin ada faktor lain yang lebih berpengaruh.

“…The use of biological indicators in river management presents several advantages, including low economic cost, rapid result generation and the capacity to offer a discrimi-nating response due to their ability to show changes under environmental disturbances. The utilization of techniques involving live organisms, particularly macroinvertebrates, stands as the most comprehensive and practical approach available today for such purposes, constituting a fundamental tool in applied biomonitoring efforts for assessing water quality [2,[10][11][12][13][14].…”

The macroinvertebrate community, physical–chemical water variables and hydromorphological indices were studied in the Turón River (Málaga, Southern Spain). Our study aims to improve the knowledge of the most influential environmental factors at different spatial and temporal scales in Mediterranean rivers, in order to establish better management of Mediterranean river ecosystems. To this end, in this work, seasonal sampling was carried out for one year to evaluate the effect of the characteristics of the drainage basin (i.e., geology, topography, land use) on the macroinvertebrate community. To this end, the environmental variables of the catchment basins were evaluated at three different scales: (i) watershed level, (ii) valley segment level and (iii) local level. The results showed that 13 environmental variables, 3 at the watershed scale, 5 at the valley segment scale and 5 at the local scale, influenced the macroinvertebrate community. Land use is the main explanatory variable at the watershed scale, while stream channel curvature is the most common variable at the valley segment scale, and the habitat assessment index is the variable with the strongest influence at the local scale. The influence of different spatial scales presented a seasonal variation. During spring, autumn and winter, the watershed scale exhibited the highest resolution (adjusted R2 = 0.20–0.29), while in summer, the local scale became the most significant in explaining the presence of macroinvertebrate taxa (adjusted R2 = 0.17). The obtained results emphasize the significance of temporal and spatial scales in Mediterranean rivers for adequate river ecosystem management.

“…They are currently considered major disciplines with considerable scientific, economic, and commercial impact. In addition to their application in detecting terrain and natural resources, these disciplines have other key social and environmental uses, such as climate change, environmental, agricultural, and food security monitoring and natural disaster management [ 1 , 2 ]. The commercialization of satellite Earth observations has seen significant growth and has traditionally served security, defense, infrastructure monitoring, agricultural, energy, and mining sectors.…”
