Drought: How Does GIS Help with Drought Prediction and Management?

Abhijeet Modi/ October 26, 2021/ Blog

Considering the increasing water demand and the sudden and unpredictable fluctuations in the weather, the focus of the researchers and farmers is on drought management these past few years.  There are several hydrological and climate-related conditions that play a significant role in determining the condition of your land and how prone it is to natural disasters, such as floods and drought.

While there is no tool that can help you collect 100% accurate data for the agricultural fields, it is believed that certain technologies like the GIS (geographic information system) play a pivotal role in the management of natural disasters. Researchers need to study and evaluate the climate conditions and the hydrological factors to understand the risks of drought in the particular environment.

Low humidity levels, high winds, and extreme fluctuations in the temperatures are a few common causes of drought. The unpredictable rain or excessive rain in the winters or other off-seasons can also increase the risk of natural disasters. Lack of adequate rainfall is the primary cause of drought, but as mentioned earlier, it is usually caused by a combination of a few environmental and hydrological factors.

This is why early detection is important for prevention. Now, the data required for the estimation of drought and risk calculation of the drought and other natural disasters in your area is collected through GIS.

The Importance of Early Prediction

This data is often associated with a spatial component, which keeps changing from time to time. Thus, it requires regular measurement and monitoring. By keeping an eye on the humidity levels, rainfall, and changes in the weather, it gets easier for the farmer to determine the chances of drought in the field.

They can take preventive measures to control the drought risks and make their land more effective.  There is no doubt that GIS has become an important element of drought assessment since the technology is widely used for the monitoring of the climate levels, humidity, rainfall, and other crucial components that make an area drought prone.

Now, the question is can this technology prevent drought. No technology can control natural disasters or predict drought accurately, although these modern tools have proven quite effective in predicting natural disasters ahead of time.

The Role of GIS in Predicting and Controlling Drought

GIS involves the remote sensors installed on the farming equipment, satellites, and agricultural land, giving you accurate insights into your agricultural field and which factors are affecting crop productivity.

Drought can destroy your farmland and the crop, which is why early prediction and the steps for preparing your land for such conditions in advance is important if you want to maintain the crop quality and productivity levels. Proper assessment of the drought risk can help improve your crop productivity and give you adequate time to prepare your land for the risks of drought effectively. This is how GIS can help you predict and control the risks associated with drought in advance so you can ensure better and higher productivity.
