What is the greatest threat to agricultural sustainability?

Climate change is a global problem that has increased the need for fresh water in farming and regular consumption. At the same time, although the demand has increased, the supply has steadily shrunk. Overall, the biggest threat to agricultural sustainability is climate change.

How global warming affects crops?

Climate change may actually benefit some plants by lengthening growing seasons and increasing carbon dioxide. Yet other effects of a warmer world, such as more pests, droughts, and flooding, will be less benign. Under the HadGEM2 model, corn farmers will see crops decline by nearly 16 percent. …
