Despite the challenges, rainfed agriculture is an important part of the economy of Karnataka. It provides employment for millions of people and produces a variety of crops, including rice, wheat, millet, and pulses.

Intensive irrigated agriculture is often used to grow high-value crops such as fruits and vegetables. It can be a very efficient way to produce food, but it can also have a negative impact on the environment, as it can lead to water shortages and water pollution.
