The world, with an increasingwith a population, currently has limited resources for food production, namely water; which is increasing getting scare, and poorly cultivated lands and agricultural potential for self-sufficiency.
The main problem is not only the infertile soil, improper farming methods and climate change.
But that the world must produce more food in the next four years more than all farmers in history have harvested over the past 8,000 years. That’s because by 2050, the earth will be home to as many as 10 million people, up from the current 7.5billion. If massive increases in agricultural yields are not achieved, matched by massive decreases in the use of water and fossil fuels, a billion or more people may face starvation.
Although, our soil-less agricultural technology and substrate is not the panacea for completely feeding the world in this regard, a broad and long-term use, continues research and development of environmentally product will be a long-term approach to provide Ghana(world as a whole) some cushion.
