Monitoring agricultural crop conditions and early assessment of production greatly benefits strategic planning for developed and developing countries. Accurate and timely assessment of decreased production caused by a natural disaster, such as drought or pest infestation, plant disease, can be critical for countries where the economy is dependent on crop production. Early assessment of yield reductions could avert a disastrous situation and help in strategic planning to meet the demands. Remote sensing technology applications for monitoring crop condition have been studied extensively during the past several decades, providing timely assessment of changes in growth and development of agricultural crops. The challenge exists in using parameters derived from remotely sensed data to quantify the changes in crop production, Limited water resources and scarcity of water is the main challenge for agricultural horizontal expanding policies and strategies., Remote sensing has plays an important role in crop identification especially in cases where the crop under observation is mysterious or shows some mysterious characteristics. The data from the crop is collected and taken to the labs where various aspects of the crop including the crop culture are studied. The specific requirement of climate and soil conditions coupled with the specialized management practices make the distribution of plantation crops rather more localized in comparison to other agricultural crops. The identification, estimation of growing stock, analysis of distribution and monitoring at regular intervals are major aspects in plantation crops., Remote sensing plays a very important role in the estimation of the farmland on which a crop has been planted. This is usually a cumbersome procedure if it is carried out manually because of the vast sizes of the lands being estimated. Remote sensing is used to forecast the expected crop production and yield over a given area and determine how much of the crop will be harvested under specific conditions. Researchers can be able to predict the quantity of crop that will be produced in a given farmland over a given period of time. In the event of crop damage or crop progress, remote sensing technology can be used to penetrate the farmland and determine exactly how much of a given crop has been damaged and the progress of the remaining crop in the farm. Remote sensing technology has also been instrumental in the analysis of various crop planting systems., Remote sensing technology plays an important role in the assessment of the health condition of each crop and the extent to which the crop has withstood stress. This data is then used to determine the quality of the crop. The physiological changes that occur in a plant due to stress may change the spectral reflectance/ emittance characteristics resulting in the detection of stress amenable to remote sensing techniques
