The impacts of climate change on food provisioning have cascading effects on key elements of food security, such as food prices, household income, food safety and nutrition of vulnerable groups . Climate extreme events are frequently causing acute food insecurity . There is growing evidence that human-induced climate warming has amplified climate extreme events , but detection and attribution of food insecurity to anthropogenic climate change is still limited by a lack of long-term data and complexity of food systems . A recent event attribution study by Funk  demonstrated that anthropogenic enhancement of the 2015/2016 El Niño increased drought-induced crop production losses in Southern Africa. Human-induced warming also exacerbated the 2007 drought in southern Africa, causing food shortages, price spikes and acute food insecurity in Lesotho .
