NDVI-based crop stress analysis for Nakuru Region, Kenya
Nakuru Region Crop Stress Analysis Using NDVI
Project Overview
This repository contains a comprehensive analysis of crop health and stress in the Nakuru region of Kenya using Normalized Difference Vegetation Index (NDVI). The analysis utilizes Sentinel-2 satellite imagery processed through Google Earth Engine (GEE) and QGIS to identify areas of crop stress and healthy vegetation.
Key Findings
45% of croplands show signs of severe stress (red zones)
40% of agricultural areas exhibit moderate stress conditions (yellow zones)
Only 15% of croplands display optimal plant health (green zones)
Western sectors show the highest concentration of severely stressed vegetation
Eastern zones demonstrate better overall plant health with patches of healthy vegetation
Technologies Used
Google Earth Engine (GEE): Cloud-based platform for satellite image processing and NDVI calculation
QGIS: Geospatial analysis and map production
Sentinel-2 Satellite Data: 10m resolution multispectral imagery (Feb-Apr 2024)
