Using Irrigation to Mitigate the Effects of Climate Change

Thanks to climate change, rainfall patterns have become erratic. So you find that in the regions of the world that are greatly affected by climate change, rainfall has become unpredictable. Such places go for long spells of time without rainfall. And then when it does rain, the rainfall tends to be excessive, leading to floods. The whole thing can (on a light note) be likened to the Walmartone schedule, which is accessible to Walmart Associates through the Walmart1 login page: where, sometimes, you have long spells of free time, followed by long periods where you are expected to be on duty.  The rainfall patterns in this age of climate change are like that: you go for long durations of time without rain, and then when it does rain, the rainfall turns out to be excessive and destructive.

Against that background, one of the ways in which we can mitigate the effects of climate change is through the use of irrigation.

Irrigation would make it possible for the people who are affected by climate change to have food, even during the long dry spells. We have just noted that thanks to climate change, people are having to go for long durations of time without rainfall. This often leads to famines: as crops dry up, and livestock ends up being left without pasture or water. So this is the gap that would be filled by the irrigation — ensuring that there is water to grow crops (and maintain livestock) throughout.

For irrigation to be viable, the rain water has to be preserved. This entails building dams. And this is yet another way in which the effects of climate change can be mitigated. For as we have just noted, another effect of climate change is where the erratic rainfall tends to be excessive (when it does rain). But if the water is carefully collected through well designed drainage systems, and directed into dams, it wouldn’t cause much damage. Thus, the harmful effects associated with floods would also have been mitigated.
