Smart Agriculture Revolution: Part 2 - Smart…The Agricultural Revolution is Digital
Agriculture faces unprecedented challenges in the 21st century. With the global population expected to reach nearly 10 billion by 2050, agricultural processes involving food production will have to increase their output by 70 percent by 2050. Climate change, resource scarcity and the need for sustainable practices are pushing farmers toward "precision agriculture" or "smart farming" solutions。
