This transformation could not arrive in a better time. The world population is expected to grow from 6.8 billion today to 9.1 billion by 2050 requiring significant growth in food production, says UN report. In addition to the increasing food demand, shrinkage of arable lands and increase in drought are also alarming problems caused by climate change. Needless to mention, with the rapid population growth, sustainable farming is more important than ever before. Considering these aspects, it might not seem to be an exaggeration that precision farming and smart agriculture are the key for survival.
