The correct answer is D) All of the above.
Climate change is a major threat to horticulture in Karnataka. The state is already experiencing the effects of climate change, such as unpredictable rainfall patterns, heat stress, and emerging pests and diseases. These factors are making it difficult for farmers to grow crops and are threatening the livelihoods of millions of people.
Unpredictable rainfall patterns are making it difficult for farmers to plan their crops. In the past, farmers could rely on a certain amount of rainfall each year. However, climate change is making rainfall patterns more erratic. This means that farmers may not get enough rain to water their crops, or they may get too much rain, which can damage crops.
Heat stress is also a major problem for farmers in Karnataka. The state is already one of the hottest in India, and climate change is making temperatures even higher. This is making it difficult for crops to grow, and it is also stressing livestock.
Emerging pests and diseases are another threat to horticulture in Karnataka. Climate change is creating new conditions that are ideal for the spread of pests and diseases. This is leading to outbreaks of pests and diseases that have not been seen before in the state.
These factors are all combining to make it difficult for farmers to grow crops in Karnataka. Climate change is a major threat to horticulture in the state, and it is important to take action to address this issue.
