During the Little Ice Age, northern and central Europe experienced frequent crop failures primarily due to the region's shift toward a climate characterized by cold winters and cool, wet summers.12

These adverse weather conditions significantly disrupted agricultural productivity:

Climatic Stress: The persistent cold and excessive moisture hindered the successful growth and maturation of essential crops.12
Harvest Ruin: The combination of cold winters and cool, wet summers specifically ruined wine harvests and prevented other crops from reaching maturity, leading to widespread famines.12
Environmental Impact: In some areas, such as the Netherlands, flooding associated with these climatic shifts destroyed reclaimed agricultural land.3

These environmental challenges were compounded by other 14th-century disasters, including the Black Death and various military conflicts, which collectively led to an agricultural recession, the abandonment of settlements, and the loss of arable land due to a lack of laborers.3
