Feeding the world has become harder and harder as the human population balloons. One of the ways that this problem is being tackled is through the use of technology to grow crops where they previously would not have been able to live. Drought resistant crops that can thrive where water is limited increase the ability of farmers to feed the world.
Drought-Associated Crop Issues
Water is not an unlimited resource, and it tends to be fairly unpredictable. All freshwater originally fell as rain, and tends to turn over fairly quickly. This means that if a given region has a dry winter, there’s less water in all of the rivers that drain from that region, potentially affected huge swaths area. Drought resistant crops are very helpful in these situations.
Farmers already plant crops that they think will grow well on their land whenever possible. However, sometimes the crop that sells the best is the one that is least likely to grow in a particular region. In these cases, people often have to make do with meager yields or switch to a less popular, less profitable crop. When the crop serves as a major food source, the situation is even more dire than loss of income.
The Development of Drought Resistant Crops
Drought resistant plants can either be artificially selected for or genetically engineered. (Read More....)
