In today's lecture, we'll discuss the impact of climate change on agriculture. One key point is that rising temperatures can actually benefit some crops in cooler regions, extending their growing seasons. However, in tropical areas, higher heat often reduces yields. For instance, a study in Kenya showed that maize production could drop by 20% by 2050 if no adaptation measures are taken. Additionally, changes in rainfall patterns, not just temperature, are critical. Farmers may need to switch to drought-resistant varieties or adjust planting schedules. But the most urgent challenge, according to the researcher, is water management, because irrigation systems are often outdated and inefficient.
