Good morning, class. Today we'll discuss the impact of climate change on agriculture. One key point is that rising temperatures can reduce crop yields, especially for wheat and corn. However, some regions in northern Europe might actually benefit, as longer growing seasons allow for new crops like sunflowers. But in tropical areas, increased rainfall variability poses a serious risk. Farmers there often lack access to irrigation systems, making them more vulnerable. To adapt, researchers suggest developing drought-resistant seeds and improving water storage techniques. For example, in Kenya, small-scale farmers have adopted rainwater harvesting, which has increased their productivity by 20% despite unpredictable weather.
