GLOBAL - Here are ten facts about how a change climate affects our ability to grow food and feed ourselves.
1. 75% of the world's poor & food insecure people rely on agriculture & natural resources for their livelihoods
2. FAO estimates that world food production must rise 60% to keep pace with demographic change. #ClimateChange puts this at risk.
3. According to @IPPC, crop yield declines of 10-25% may be widespread by 2050 due to #ClimateChange
4. Rising temperatures are predicted to reduce catches of the world's main fish species by 40%.
5. Although global emissions from deforestation have dropped, deforestation & forest degradation account for 10-11% of global greenhouse gas emissions. Emissions from forest degradation (logging & fires ) increased from 0.4 to 1.0 gt cO2 per year between 1990 & 2015.
6. Livestock contributes nearly 2/3 of agriculture's greenhouse & 78% of its methane emissions.
7. #ClimateChange can transfer risks of food-borne diseases from 1 region to another, threatening public health in new ways.
8. FAO estimates that the potential to reduce emissions from livestock production (methane esp.) is about 30% of baseline emissions.
9. Currently, 1/3 of the food we produce is either lost or wasted. The global costs of food wastage ≈$2.6 trillion/yr, including $700 billion of environmental costs & $900 billion of social costs.
10. Global food loss & waste generate about 8% of humankind's annual greenhouse gas emissions.
