摘要：

Drought impacts economy, ecology, society, and agriculture. Depending on investigating the normalised difference vegetation index (NDVI), the vegetation condition index (VCI) is used to monitor drought due to its dependability and efficiency in studying climatic and environmental events. Dryness in Barry, Wales, UK and its impacts on vegetation are monitored using remote sensing and geographic information systems. Aerial time series data of Landsat images for 1974, 1984, 1994, 2004, 2014, and 2023 from the multispectral scanner (MSS), thematic mapper (TM), enhanced thematic mapper plus (ETM+), and operational land imager (OLI) are inspected. VCI-based drought was greatest in 1994, weaker in 1974, and expected in 2023. According to VCI, average precipitation lowered drought intensity in 1984, 2004, and 2014. 1994 lost the most vegetation comparing to 1974, 1984, 2004, 2014, and 2023. These results show how the VCI helps identify drought patterns and how ecological variables interact with drought. Copyright © 2024 Inderscience Enterprises Ltd.
