The necessity of the cutting edge technology such as Remote Sensing is mounting worldwide day by day, for its unique ability to measure or collect information of an object or phenomenon, by a recording device that is not in physical or intimate contact with the object. In practice, remote sensing is the utilization at a distance (as from aircraft, spacecraft, satellite, or ship) of any device for gathering information about the environment and/or areas in a fast and cost-efficient manner.
Remote sensing provides important coverage, mapping and classification of land cover features, such as vegetation, soil, water and forests, Urban Planing. Respondents emphasized that remote sensing could therefore be effectively used to generate significant agricultural statistics for forecasting irrigation timings, harvest timings, price fluctuations, food availability and input requirements.

Further, members suggested generating information on marketing, food processing, cottage industries, infrastructure, forestry, fisheries, health, education, road, transport and any other basic information that would support agriculture and allied activities.
The Monitoring and assessment on natural disaster in agriculture contains monitoring on soil moisture content and dry and flooding disasters. The monitoring on soil moisture content and dry disaster is used with thermal inertia and vegetation water supply, combined with date of ground actual survey of soil moisture, to establish monitoring model of soil moisture and assess dry situation on the basis of type of crops and periods of growing and development. The monitoring on flooding disaster is applied with climatic sat ellite image to obtain information on scale of flood and logging and time etc, and disaster statistics and loss assessment are conducted by integration with GPS and monitoring on crop growth.

Global crop forecasting;
Remote Sensing in agriculture and natural resource management is an important promising tool in agricultural information and management system. Comprehensive, reliable and timely information on agricultural resources are very much necessary for a country like India whose mainstay of the economy is agriculture. In fact, agricultural survey is a backbone of planning and allocation of the limited resources to different sectors of the economy.
The country needs to use this technology more and more to address various agricultural / environmental problems like water management system, in the estimation of soil nutrient profile, water profiling, biotic and abiotic plant stress, crop coverage, pest conditions and surveillance, deforestation, biodiversity assessment, marine biology, and so on. Potential of remote sensing technology could be immense – especially in conjunction with the rapidly developing information and communication technology for the benefit of the farming communities.
