IPCC Report
Topic: Environment
Context: Climate change induced droughts have been a major driver of food insecurity says IPCC Report.
Concept:
- During 1983-2009, over 454 Mn ha of croplande., 3/4th of the global harvested area (34% global calorie production) was devoured by Droughts and the production losses amounted to $166bn.
- Similarly, extreme weather led to cereal production loss of 9-10%.
- In this scenario, if Global warming over pre-industrial levels rises to 40C from 10C, rice production may decrease 30% (instead of 10%) and maize production to 70% (instead of 25%).
- Further, Yield losses were about 25% and the losses in high-income countries (8-11%) were higher than in low-income countries.
- The report says, from 2006-2016, droughts contributed to food insecurity and malnutrition in northern, eastern and southern Africa, Asia and the Pacific.
- It also cautioned that overall irrigation water demand would increase by 2080.
- Both food and the water sectors would be negatively impacted by global warming with higher risks at 2 °C than at 1.5°C.
- Evidence of floods on food production was limited, as per the report.
- While overall agricultural productivity has increased, climate change has slowed this growth over the past 50 years globally.
- The impact on food availability and nutritional quality will increase the number of people at risk of hunger, malnutrition and diet-related mortality. This will particularly impact indigenous peoples, small-scale food producers and low-income households as well as children, elderly people and pregnant women.
