The correct answer is D) All of the above.
Pollution, depletion of groundwater, and inter-state water disputes are all major challenges in managing Karnataka’s water resources.
Pollution of water resources can occur from a variety of sources, including industrial waste, sewage, and agricultural runoff. This pollution can make water unsafe for drinking, bathing, and irrigation. It can also harm aquatic life and ecosystems.
Depletion of groundwater is a major problem in many parts of Karnataka. Groundwater is used for drinking, irrigation, and industrial purposes. However, groundwater is being extracted at an unsustainable rate, which is leading to a decline in the water table. This decline can have a number of negative impacts, including water shortages, land subsidence, and saltwater intrusion.
Inter-state water disputes are another major challenge in managing Karnataka’s water resources. Karnataka shares its water resources with several other states, including Andhra Pradesh, Telangana, and Tamil Nadu. These states often have competing demands for water, which can lead to disputes over how water should be allocated. These disputes can be complex and difficult to resolve, and they can have a significant impact on the water resources of all the states involved.
These are just some of the major challenges in managing Karnataka’s water resources. These challenges are complex and interrelated, and they require careful planning and management in order to be addressed effectively.
