Role of Remote Sensing and GIS Strategies to Increase Crop Yield

Food is the most important and basic requirement for the life of human beings on the planet earth. The quality and the quantity of food from agricultural land is one of the significant parts of our socio-economy venture. It also shares the major part of GDP for a developing country. As the humankind population is increasing, the requirement of more crop yield is also rising. To increases productivity, it is required to use our agricultural lands more efficiently. This can be done by utilizing the natural resources that are soil and water efficiently. Remote sensing and Geographical information system (GIS) are the techniques that can be used for this purpose. These technologies can provide the database for making the crucial decision for the beneficiary of the agricultural sector. These data provide the decision-making capabilities for agricultural and soil management and can be embedded with GIS to maximize its reach at the sector's grassroots. This paper discusses all the major potential applications for agricultural and soil management using remote sensing and GIS. Techniques based on remote sensing that can be utilized for the application that can maximize the net yield production of the crop are discussed in detail.
