What is a concern associated with using groundwater for irrigation during droughts?

Using groundwater for irrigation during droughts presents a significant concern due to the potential depletion of groundwater supplies. Groundwater serves as a critical resource for agricultural practices, especially when surface water is scarce due to dry conditions. Relying heavily on groundwater during these times can lead to the over-extraction of aquifers, which are underground layers that store water. This over-extraction can result in diminished water levels in the aquifers, impacting long-term sustainability and potentially leading to problems such as land subsidence, reduced water quality, and the degradation of aquatic ecosystems.

The depletion of groundwater supplies poses a risk not only to current agricultural practices but also jeopardizes future water availability for communities and natural habitats that rely on these water sources. Therefore, understanding this concern is crucial for effective water management and ensuring that both immediate agricultural needs and long-term water sustainability are addressed.
