Intense soil erosion in the northern part of Gerecse Hills, Hungary, is causing significant damage to vineyards area. Three Neszmély Wine Region were investigated quantify amount eroded soils. The method was based on monitoring for one-year between July 2019 and June 2020. Every season, a set photographs taken from an unmanned aerial vehicle. images processed photogrammetric workflow produce hi...

The aim of this study was to propose a methodological approach determine the best land use based on USLE model parameters, using watershed as planning unit. parameters were spatialized software ArcGis 10.5, for case Cachoeira Cinco Veados watershed, RS-Brazil, and erosive values categorized according methodology Ribeiro (2006). We reclassified areas in “suitable” “not suitable” tested use, two ...

فرسایش خاک یکی از مهم­ترین مسائل محیطی در دنیا بوده که عامل مهم بروز خسارات بزرگ اقتصادی و تهدید جدی برای توسعه پایدار محسوب می­شود. در مقیاس حوضه­ای، عوامل متعددی در زمینه­سازی و تشدید فرسایش دخیل هستند. در فرسایش خاک توسط رواناب­ها عوامل داخل حوضه­ای مانند خاک، توپوگرافی، تراکم زهکشی والگوی کاربری نقش مهمی ایفا می­کنند. در مناطق نیمه­خشک وضعیت فرسایش خاک در محیط­های کوهستانی و در سطح زمین­های...

Soil erosion is a serious worldwide environmental problem that stems from a combination of several factors such as agricultural intensification, deforestation, increasing population, and rainstorms. This phenomenon produces a soil fertility decline, removes soil rich in nutrients and increases natural level of sedimentation in the rivers and reservoirs reducing their storage capacity as well as...

As one of the key tools for regulating human-ecosystem relations, environmental conservation policies can promote ecological rehabilitation across a variety of spatiotemporal scales. However, quantifying the ecological effects of such policies at the regional level is difficult. A case study was conducted at the regional level in the ecologically vulnerable region of the Loess Plateau, China, t...
