With the world's population expected to hit 9.6 billion people by 2050, the world is going to need to increase its food supply by 70 percent. But the shrinking availability of arable land and fresh water isn't going to make that any easier. Climate change is bound to create problems as well.

So, you guessed it agriculture is going to have to get "smart," just like every other industry.

Integrating technology with farming can mean a lot of things but primarily it will mean using Big Data to monitor crucial factors in the process of cultivating crops and livestock.

Saverio Romeo, a leading researcher in the smart agricultural field, gives Forbes an example: “Sensors are installed in various location in the fields in order to have data about the soil and the plants and then this data is used to prevent diseases such as the peronospera... I would like to highlight the fact that the aim should not be ‘industrializing’ agriculture, but make agriculture more efficient, sustainable and of high quality. We should not look for revolutions. We should look for re-interpretation of the farming practices through use of data-centric technologies. And this re-interpretation should be placed also within a new vision of rural areas.”
