Question

Climate change and an increasing population present an unprecedented challenge for food security in the coming decades. Propose and justify one or more ways in which we could increase or safeguard food production.

Answer 1

The largest threat to the ecology and biodiversity of the planet in the decades to come will be global climate disruption due to the build-up of human generated greenhouse gases in the atmosphere. Global warming could lead to an increase in pest insect population, harming yeilds to staple crops like wheat, soybeans, and corn. Another problem for affecting food production is human population. Food production depends on croplands and water supply, which are under strain as human populations increase. Still we can ensure food security by developing a set of ways to improve global food security

• Raise low water productivity

Water is a major issue for food production. Improving irrigation systems and planting crops that use less water would be an effective way to tackle this. For example, rice and sugarcane are among the crops that need more water But by providing better irrigation facilities for conserving water could control the usage of water.

• Increasing variables using genetics in crops

Increasing the use of genetically modified plants could increase food production at a higher level by having high resistance to pests, increased nutritional yield and so on.
