This study was done to assess the vegetation trend of agricultural hub of Nepal as well as the vegetation-rich area, the Terai belt of Nepal, Province 2. A satellite based data obtained from Moderate Resolutions Imaging Spectroradiometer (MODIS) were analyzed for this study.
Major Findings
- With Cubic Spline function, the seasonal patterns were obtained, and use of the linear regression model helped in obtaining the NDVI trend.
- The seasonal pattern of the NDVI showed the peak increase of the NDVI values on the rainy season i.e. during the August-October time, and the gradual decreasing pattern was obtained.
- Nevertheless, huge declining was seen during the March-June time. Viewing from the perspective of the NDVI trends, the trend is non-linear and changes slightly per year.
