The Vegetation Index is a numerical value that indicates the health and density of vegetation in a specific area. It is commonly derived from satellite imagery and helps scientists monitor plant growth, agricultural productivity, and environmental changes. The most widely used index is the Normalized Difference Vegetation Index (NDVI), which compares the difference between near-infrared and visible light reflected by plants. By analyzing the Vegetation Index, researchers can assess the impact of climate change, land use, and natural disasters on ecosystems. This information is crucial for effective land management, conservation efforts, and agricultural planning, ensuring sustainable practices for future generations.
