rice in northern Italy, olive oil In Spain and barley in the UK they have seen a significant yield reduction due to environmental conditions.
With global warming increasing the potential for extreme weather, many foods around the planet are set to become even more scarce.
This means that many of the staple foods that people consume on a daily basis will become more expensive.
How does climate change affect food production?
Recent research shows that climate change is now a serious threat to global food security.
a Report released in May by the International Panel of Experts on Sustainable Food Systems (IPES) that described climate change as an “endemic and widespread” threat to the food supply. This is also exacerbated by the high cost of living and conflict in Ukraine.
DroughtAnd the heat wavesAnd the Flood New pests prevent producers from obtaining a reliable crop in many regions of the world.
Since pre-industrial levels, global temperatures have risen by 1.1°C. The Intergovernmental Panel on Climate Change (IPCC) has warned That if that reaches 1.5°C, about 8 percent of the world’s agricultural land will be unsuitable for agriculture.
Crop productivity decreases at high temperatures due to dryingshrink in vaccination and slower photosynthesis. When exposed to high temperatures and droughts, plant defenses fail and crops become vulnerable to pest and disease-causing attacks Pathogens.
Extreme weather also causes difficulties for livestock and fisheries. The problems are set to worsen if efforts are not made to tackle carbon emissions.
The Intergovernmental Panel on Climate Change (IPCC) recently released a report that confirmed that human-induced climate change is causing droughts and floods, Forest firesheat waves more severe and more frequent.
According to the United Nations, the combined effects of climate change, conflict Poverty may lead to an additional increase in food prices 8.5 percent by 2027. The report warns that millions of people already face severe food insecurity.
Rising cost of staple grain crops due to climate change
This summer alone, heat waves withered farmland IndiaFires in Tunisia destroyed grain fields, and floods in them China He destroyed nearly 100,000 hectares of crops.
Basic foods such as wheat, rice, corn and soybeans were destroyed all over the world causing prices to rise.
The rising costs of these major crops have plunged populations in Africa, Asia and South America into severe food poverty. in SomaliaFor example, the price of a 400-gram packet of wheat has doubled since February. In India, wheat flour exports have been restricted to ease high domestic prices.
Within Europe, drought in the north ItaliaThe agricultural heartland of Egypt has seen production of crops such as rice and corn cut off. The extreme temperatures and lack of precipitation also affected Tomatoesgrapes and olive.
An IPES report in May found that wheat prices reached a 14-year peak in March and corn prices reached an all-time high.
Basic foods are also affected by new pests and pathogens. In the United States this year, bird flu has caused prices to increase by nearly 300 percent egg.
Seafood is getting scarcer as sea temperatures rise
The seas of Europe also suffer from the heat. Iceland’s waters lose mainly fish to the local diet as capelin and cod swim north to find cooler temperatures.
But shellfish such as clams, clams, and mussels cannot escape warm waters. In northern Italy, crustaceans die in the Adriatic.
In the Po Delta, where the vast Bo . River Flowing into the sea, clams and mussels are especially valuable because of the unique aquatic conditions where freshwater and saltwater mix.
Now, fishermen say the oysters are suffering because the river’s historically low water levels mean so little fresh water flows into the delta, making it highly saline.
Global warming is driving up prices for chocolate, coffee and wine
Luxurious foods like coffeeChocolate and wine are also at risk. Increasing temperatures in the coffee growing regions of Central and South America, Indonesia and Vietnam will make production more difficult.
Between 2020 and 2021, extreme temperatures in Brazil raised the price of coffee by 70 percent, according to the International Monetary Fund.
As for the chocolateMost cocoa grows in Ivory Coast and Ghana where drought may soon make the area unsuitable for growing the crop.
Vineyards in California and Europe experience extreme weather, from non-seasonal frosts to droughts and wildfires. With low fruit yields, the prices of wine production will be higher.
In France, the production of mustard seeds was damaged by drought which caused a shortage of spices.
Meat consumption may soon come with a tax
Meat may start to cost more due to its impact on climate change. Livestock contribute to global warming emissions and destroy forests and wildlife to make way for land to grow animal feed.
This has led to some governments proposing a tax on beefPork and chicken. Before the war in Ukraine, the agricultural ministers of Germany and the Netherlands were considering a tax on meat.
Search The publication in the Journal of Environmental Economics and Policies predicted a potential price increase of 35 percent to 56 percent for beef, 25 percent for poultry, and 19 percent for lamb and pork in high-income countries.
Can heat-resistant plants be developed to withstand climate change?
Scientists at US and Chinese universities are exploring ways to protect crops in an increasingly warming world. They are studying how to help plants survive intense heat Hoping to protect the global food supply.
But IPES researchers also warn that immediate action is needed to reduce emissions to avoid higher food prices in the near future.
If this is neglected, experts said, the world will find itself “falling asleep in the catastrophic and systemic food crisis of the future”.
