The aim of this study is to analyze the performance Drought Severity Index (DSI) in Romania and its validation based on other data sources (meteorological data, soil moisture content (SMC), agricultural production). Also, it assess drought a multi-temporal analysis trends DSI obtained from Terra MODIS satellite images. standardized product evapotranspiration (ET) Normalized Difference Vegetation (NDVI), highlighting differences over certain period time compared average. areas are located...
Land degradation (LD) and desertification (DS) are a sensitive global issue including southern south-eastern Europe, which is severely affected by climate change. In this study, state-of-the-art approach for assessing the intensity of LD DS processes using remote-sensing-derived indicators within GIS environment was proposed. The analysis carried out Principal Component Analysis based on integrating significant trends relevant biophysical parameters in Romania. methodology tested validated...
This paper will assess the sensitivity of soil moisture anomaly (SMA) obtained from Soil water index (SWI) product Metop ASCAT, to identify drought in Romania. The SWI data were converted relative values (%) absolute (m3 m-3) using porosity method. conversion results (SM) validated situ measurements ISMN at 5 cm depths (2015-2020). SMA was computed based on a 10 day product, between 2007 and 2020. analysis performed for (near surface), 40 (sub 100 (root zone). standardized precipitation...

Abstract Drought is one of the most significant extreme event facing world, affecting society and environment. Located in SE Romania, Dobrogea Region characterized by a temperate climate with strong continental influences, being affected drought episodes which cause damages economic costs over extensive agricultural areas. Risk reduction, continuous vegetation monitoring, management implementation are facilitated complementary use indices biophysical parameters derived from satellite...
Irrigated agriculture will be impacted by climate change as average temperatures and rainfall variability increase. This trend continue in the future, according to numerical experiments with models, but how it develops strongly influenced anthropogenic emission levels of greenhouse gases. However, effects have not been, be, uniform across regions or over time because human-induced warming is superimposed on natural (IPCC, 2021). Recent studies (Caian et al., 2023) focused projected changes...
Evapotranspiration is an essential element in the water cycle, being estimated through various methods such as Penman-Monteith equation, Priestley-Taylor FAO-56 Surface Energy Balance Algorithm etc. With advent of satellite imagery, constant efforts have been made to improve spatial resolution ET estimates integration high-resolution remote sensing data. based on MODIS data utilizes resulting a product at 500 meters over period 20 years (2001-2023). Recently, new estimation tools for...
In Romania, excessive fragmentation of croplands remains persistent in areas significant agricultural potential as a consequence combined factors involving both land governance and farms’ characteristics. This paper examines the use Romanian Plain, focusing on impact policies implemented Romania during past three decades. The analysis relies survey local that helps to distinguish phases marked evolution 1990–2020. Additionally, metrics derived from remote sensing time series further assist...
Abstract Hail is one of the dangerous meteorological phenomena facing society. The present study aims to analyze hail event from 20 July 2020, which affected villages Urleasca, Traian, Silistraru and Căldăruşa Traian commune, Baragan Plain. analysis was performed on agricultural lands, using satellite images in optical domain: Sentinel-2A, Landsat-8, Terra MODIS, as well product radar Soil Water Index (SWI), weather data. Based Sentinel-2A images, a threshold 0.05 Normalized Difference...
