One way to solve food shortages is to enhance green technologies, according to Live Science. Science can also merge with technology by using optical sensors to scan crops and adjust fertilizer levels to the needs of different plants.
Live Science notes a form of technology called multi-crop machines, allowing farmers to plant a variety of crops in various conditions. This allows farmers to grow diverse foods, instead of relying on a staple crop. Reducing plowing is another method that can yield more crops. Plowing involves preventing the spread of weeds, but it also breaks down the integrity of the soil. Reduction in plowing preserves the soil and leaves straw residue across fields, producing rich and successful crops.
Live Science also mentions researchers from the Netherlands working on animal-free meat products. This involves growing synthetic meat with the help of stem cells. The nonprofit group New Harvest believes a single cell can sustain the world's meat supply annually.
Providing massive irrigation systems is also another way of solving food shortages, according to the Adventist Development and Relief Agency. Better irrigation methods allows farms in places like Africa to grow plentiful crops and provide water for livestock.
According to the Borgen Project, the world can also donate $30 billion a year to eradicate world hunger.
