Seasonal fluctuations in food production
- Short duration of growing season
- Seasonal variability in food supplies
- Weather-induced fluctuations in agriculture
- Seasonally determined diets
- Fluctuation in availability of food
Nature
Typically from around June to October, this period is also commonly referred to as the 'hunger season' or the 'lean season'. The availability of food varies from season to season and may be severely affected by the weather, especially when this gives rise to floods, heat waves (droughts), and cold spells. Environmental degradation can increase vulnerability to these effects. The growing dependence on a limited number of crop varieties over large areas may amplify the effects of weather and pest damage. Climate change increases the risk whilst raising the challenge of accurate forecasting.
Fluctuations in food production can cause transitory hunger at local levels and impact the global food markets.
Incidence
In 2021, India faced severe seasonal fluctuations in food production due to unseasonal rains during the harvest period, particularly affecting wheat and mustard crops in Punjab and Haryana. The unexpected weather patterns resulted in a reported loss of around 10-15% of the expected yield, impacting farmers' incomes and food availability in local markets. This incident highlighted the vulnerability of agricultural systems to climate variability and the urgent need for adaptive strategies to mitigate such seasonal impacts.
