Climate Change and Food Security
Home​​
Global warming induced heat waves, drought, and flooding constitute a global food security emergency ​for us all today, ​to protect our near and long term future food security​- the world's top food producing regions of the temperate Northern hemisphere ​are now global warming & climate change vulnerable


19 Dec 2014 Climate change cut to world food output 18% by 2050 ​​
Changes in climate are already affecting the sustainability of agricultural systems and disrupting production
​Unless the emissions of GHGs are curbed .. changes in temperature, precipitation, and other climate variables will undoubtedly affect agriculture around the world

Climate change: how a warming world is a threat to our food supplies
Global warming is exacerbating political instability as tensions brought on by food insecurity rise. With research suggesting the issue can only get worse we examine the risks around the world. The Observer 13 April 2013

"In addition to conflict and violence in many parts of the world, the gains made in ending hunger and malnutrition are being eroded by climate variability and exposure to more complex, frequent and intense climate extremes: FAO Nov 2018 State of World Food Security
9. "Agriculture Rising temperatures, extreme heat, drought, wildfire on rangelands, and heavy downpours are expected to increasingly disrupt agricultural productivity in the United States. Expected increases in challenges to livestock health, declines in crop yields and quality, and changes in extreme events in the United States and abroad threaten rural livelihoods, sustainable food security, and price stability."

"Food Security Observed climate change is already affecting food security through increasing temperatures, changing precipitation patterns, and greater frequency of some extreme events (high confidence)."
"Food security will be increasingly affected by projected future climate change (high confidence)."

September 2019 Global Commission on Adaptation Global demand for food will increase by 50 percent and yields may decline by up to 30 percent by 2050 in the absence of ambitious climate action.

8 Oct 2019, FAO " Agriculture is a weather-dependent sector, and the impacts of climate change may cause more frequent and intense droughts and floods, the spread of pests and diseases, and the degradation of ecosystems. At the same time, agriculture is also faced with the responsibility and pressure to reduce emissions,"
