What the main cause of 14 century famines?

The main cause of the 14th-century famines was a combination of climate change, specifically the Little Ice Age, which led to colder temperatures and erratic weather patterns that negatively affected agricultural production. Additionally, overpopulation in some areas put pressure on food supplies, while social and economic factors, including wars and the Black Death, further disrupted food distribution and access. These factors collectively resulted in widespread food shortages and subsequent famines during that period.
