Will we be able to feed future populations?
Artificial selection
Artificial selection to produce varieties of plants that are suited to particular climates and soil types, and breeds of animal for a specific purpose such as optimum meat, milk, and wool production.
Adoption of modern technology and methodology
Robots
By using machines, it drives down the costs of keeping the food fresh and increases productivity. The number of robots in the European food industry is well over 30,000, while the number of robots per 10,000 employees rose from 62 in 2013 to 84 in 2017.
Growing plants in labs as it is cheaper and faster to grow food. Grains are easier to grow this way.
Reducing food waste
Reducing food waste by 25% can close the food gap by 12%. Some steps to ensure that food does not get wasted would be improving food storage in developing countries and streamlining best before dates.
Stopping Expansion
Growing two plants at the same time using the same cropland can decrease the expansion
Adapting to climate change
Start to grow crops that will grow better in the weather that they are facing meaning that they get food even if there isn’t much rain. Another way would be to form water conservations systems. Places like Africa are mostly affected by climate change and growing crops there is vital so this method is important for them.
Boosting pasture and livestock productivity
As meat’s demand will increase by 70% by 2050 so trying to make use of the land that is already being used will make sure we get more output from the farms. Ways to do this would be improving feed and fertilizers of pasture and veterinary care.
Soil Management
Ways to improve this would be planting more trees. Zambia has started doing this and has seen an increase in maize yield of 88-190% compared to places that don’t have trees.
Shifting diets
only 55 percent of the world’s crop calories feed people directly
For every 100 calories of grain we feed animals, we get only about 40 new calories of milk, 22 calories of eggs, 12 of chicken, 10 of pork, or 3 of beef.
The estimate for future populations are
8.6 billion in 2030
9.8 billion in 2050
11.2 billion in 2100
