Land, water, soil and natural environment have been impacted while maintaining crop production. Decision making in agriculture is based on indiscrete, static, and sporadic information. The geographically integrated information is not effectively used. Climate change could alter the land-water-agriculture practices on a large scale. It is imperative to use the geographically referenced present and historical (space and time) information for decision making process in agriculture. This course offers an overview of GIS and agriculture applications. You can also understand geospatial information made available by many agencies and individuals, and can start knowledge based smart agriculture practices.
