“…The NDVI has been categorized into eight classes including urban and built-up lands, savannas, open shrublands, non-vegetated lands, grasslands, croplands, water bodies, and closed shrublands. Several studies have used NDVI to detect, assess, and monitor drought (Nanzad et al, 2019) and land degradation (Higginbottom and Symeonakis, 2014;Kumar et al, 2022). This index also estimates agricultural production (Roznik et al, 2022) and map fire risk (Michael et al, 2021).…”

The study investigates the land use and land cover (LULC) in Errachidia province (Pre-Saharan of Morocco) in the period 2005–2020. To this end, remote sensing (RS) tools such as LULC, the normalized difference vegetation index (NDVI), the normalized difference water index (NDWI), the Enhanced Vegetation Index (EVI), Gravity Recovery and Climate Experiment (GRACE) satellite data, and precipitations were processed and combined. The monitoring of LULC over this period reveals different changes in this area. Generally, for water bodies, two trends can be observed, an increasing trend since 2006 and a decreasing trend from 2011 to the present. However, an increasing trend was recorded for the urban-and-built-up-lands and the grasslands categories. NDVI, NDWI, and EVI showed three major peaks recorded in the same periods (in 2007, 2009, and 2015). In terms of water storage, three phases were found. The first depicted the lowest groundwater quantities with a decreasing trend, which corresponds to a period of drought and/or human pressure. The second phase, the most important that recorded the greatest storage of water while the third phase corresponds to low storage with a decreasing trend. LULC of croplands reveals a slightly increasing trend from 2012 to 2020, which shows an orientation to an extension of crops mainly of date palm encouraged by government programs. A strong correlation between the seasonal NDVI and water storage using GRACE-Data for the period was found. In the end, recommendations on the adaptation to CC were proposed. The findings demonstrate that RS techniques are useful tools to detect hydrological droughts, observe, and conserve land resources. In arid areas such as Errachidia, the solution lies in rationalizing the use of water resources protecting them from uncontrolled anthropogenic events, which may alleviate the pressure. To support local sustainable development, environmental scientists and decision-makers may use the outputs of this study.

“…To ensure accurate land cover analysis reflecting habitat quality, the land cover data were derived from Landsat 8 image bands (Gemeda et al, 2023;Yu et al, 2015). Prior to the classification of Landsat images, preprocessing steps were employed to enhance the quality of the imagery (Kumar et al, 2022). The radiometric corrections were applied to calibrate the data, remove atmospheric effects and normalise the influence of light factors using QGIS 3.28.2.…”

Habitat heterogeneity plays a vital ecological role in influencing community ecology dynamics. We evaluated the relationship between habitat heterogeneity and land‐use cover with avian community structure in the human‐dominated landscape of the Katavi‐Rukwa ecosystem in Tanzania. We used the fixed‐radius point count method to record birds in different habitats. We calculated the relative abundances and the Shannon‐Wiener diversity index of bird guilds across habitats as well as the Normalised Difference Vegetation Index (NDVI) and estimated land‐use cover of the study area from Landsat 8 images. We grouped birds into five major guilds: Insectivore, Granivore, Omnivore, Carnivore and Nectarivore. Among the guilds, Insectivores, Omnivores, Nectarivores and Carnivores were positively correlated with an increase in NDVI, while Granivores were negatively correlated with an increase in NDVI. Among the habitats, woodland had high species diversity whereas riverine had low species diversity. Our findings highlight the importance of habitat heterogeneity in biodiversity conservation in human‐dominated landscapes, and we suggest implementing conservation in these landscapes.

“…Remote sensing uses electromagnetic radiation sensors to record images of the earth's Environment that can be interpreted to produce helpful information (Read & Torrado, 2009). Utilization of image results captured by satellites with different sensors (such as TM, OLI, TIRS) has an excellent ability to determine surface characteristics by using re ected waves at speci c wavelengths (Kumar et al, 2022;Acharki, 2022;Thenkabail et al, 2005).…”

“…These changes can affect the region's temperature and cause local warming (Wong & Yu, 2005; Srivanit & Hokao, 2013; Wibowo & Salleh, 2018). This warming on a local scale can be detected using satellite sensors which are often used to see patterns of Land Surface Temperature (LST) or surface temperature (Kumar et al, 2022;Sahani, 2021;Cilek & Cilek, 2021). Variation of surface temperature in various urban landscapes is strongly in uenced by the dominant land cover and land use in the region (Njoku & Tenenbaum, 2022).…”

Sumedang Regency has experienced considerable development in recent times. They started by expanding residential areas and toll roads to construct the Jatigede Dam. Changes in land cover may influence the temperature above and around it. This study aims to analyze the spatial pattern of surface temperature in Sumedang Regency between 2007-2022 based on land cover changes regarding the Local Climate Zone and heat hazard threat. The data used are Landsat TM, Landsat OLI/TIRS, and Landsat OLI-2/TIRS-2 images. The data is taken and processed using Google Earth Engine. The results found an increase in LST from 2007 until 2022, with the most significant increase occurring in 2022. This increase is accompanied by changes in land cover in Sumedang Regency. This increase is accompanied by changes in land cover in Sumedang Regency. Land surface temperatures in Sumedang Regency have continued to increase from 2007 until 2022, and based on the observed urban heat signature, the most significant increase in average temperature occurred from 2007 to 2022 (4.68℃). The strong heat stress category can cause dynamic thermal sensation (DTS), a core-to-skin, and an increase in rectal temperature. Extreme heat stress can cause an increase in rectal temperature time gradient, a steep decrease in total net heat loss, and a steep increase in average sweat rate.
