The remote sensing technique has been used for diverse applications in agriculture. An array of continuous narrow wavebands in the hyperspectral remote sensing provide an understanding of the subtle changes in biochemical and biophysical attributes of crops and their different physiological processes. Hyperspectral remote sensing has also been used in discrimination of crops and their cultivars, assessing abiotic and biotic stresses, quantitative estimation of crop nutrient status and soil health. Knowledge of biotic and abiotic conditions over large areas bears the potential to reduce agricultural losses in terms of productivity. Therefore, this article aims to present an overview of the quantification of different biotic and abiotic stress by remote sensing techniques and focuses on future directions for researchers.
