This study examines the impact of climate change on agricultural productivity in a developing country. Using a panel data approach, we find that temperature increases lead to significant decreases in crop yields, particularly in maize, wheat, and rice. Our results also suggest that population growth exacerbates the negative effects of climate change on agricultural productivity. Policy interventions that focus on reducing greenhouse gas emissions and improving agricultural technology are needed to mitigate these impacts.
