Wildfires have become one of the biggest natural hazards for environments worldwide. The effects wildfires are heterogeneous, meaning that magnitude their depends on many factors such as geographical region, climate and land cover/vegetation type. Yet, which areas more affected by these events remains unclear. Here we present a novel application Generalized Synthetic Control (GSC) method enable...
سابقه و هدف: رطوبت خاک یکی از متغیرهایی است که با کنترل فرایند تبخیر و تعرق بر چرخهی تبادل آب و حرارت بین زمین و اتمسفر تأثیر میگذارد. مقدار این رطوبت برای چرخههای هیدرولوژیکی، بیولوژیکی و بیوشیمیایی نیز حائز اهمیت میباشد. به کمک اطلاعات رطوبت خاک در بازههای زمانی منظم میتوان درجهی پیشرفت خشکسالی را در مناطق با آّب و هوای خشک تعیین کرد. همچنین پایش مستمر رطوبت خاک مناطق کشاورزی، به برنامه...
Degraded peatland is caused by forest clearing and the construction of artificial water networks. When management not implemented across land uses in entire landscape, then it will be a big issue that causes deficit leads to increasing droughts fires. Effective restoration must first identify part Peatland Hydrological system Units (PHUs) with insufficient storage resources. This study used int...
Marshlands in arid and semi-arid areas are considered constantly changing environments due to unsecured water supplies as a result of high evapotranspiration limited highly variable rainfall. Classification marshlands these regions mapping their land cover is not an easy task maps need be upgraded frequently. Satellites provide enormous amounts information data for the continuous monitoring cha...
Abstract Land fires lead to a deterioration of environmental quality and have perilous social economic aspects. One method for mitigating this hazard is determine the range fire risk areas. Thus, study aimed analyze current potential future in Ogan Komering Ilir, southern Sumatra region Indonesia, using CMIP6 data geospatial technology. In order areas, Landsat 8 satellite image from 2021 (as ba...
Mangroves, which are vulnerable to natural threats and human activities on small islands in the tropics, play an essential role as carbon sinks, helping mitigate climate change. In this study, we discussed effect of factors mangrove sustainability by analyzing impact rainfall, land surface temperature (LST), tidal inundation greenness mangroves Karimunjawa National Park (KNP), Indonesia. We use...
This paper reports a semi-automated workflow for detection and quantification of forest damage from windthrow in an Alpine region, particular the Vaia storm October 2018. A web-GIS platform allows to select damaged area by drawing polygons; several vegetation indices (VIs) are automatically calculated using remote sensing data (Sentinel-2A) tested identify more suitable ones quantifying cross-v...
Abstract Rice is the primary source of nutrition food more than half world’s population, and it hugely important in global economic growth, security, water use, climate change. The need for satellite systems to monitor rice crops assist crop management gaining popularity. European Space Agency’s (ESA) launched Sentinel-2 A + B twin platform’s which enhanced temporal, spatial, spectral resolutio...
Abstract Forest fires destroy these areas and have devastating harmful socio-economic environmental effects. One of the methods preventing managing hazards created in field forest is to determine range fire risk. The purpose this study high-risk forests Golestan province using remote sensing data information. For purpose, MODIS satellite during years 2005 2020 for middle November mid-February, ...
