World olive oil manufacturing, in hundreds of thousands of tonnes, from 2000-24. Credit score: Carbon Transient, based mostly on figures from the Worldwide Olive Council.
Because the above chart exhibits, international olive manufacturing has dropped considerably since 2021. Manufacturing dropped by roughly one-third between 2021 and 2024.
In consequence, the value of olive oil has soared in several elements of the world. In January 2024, the fee had risen by virtually 70 per cent in Portugal in comparison with January 2023, in response to Eurostat. Costs had been up by 50 per cent within the EU, on common, throughout this time interval.
Olive oil is now the “most stolen product in supermarkets throughout Spain” because of the price ticket, the Guardian reported in March.
Gross sales “plunged” in elements of the Mediterranean attributable to “steep value rises”, the Monetary Instances wrote earlier this 12 months. The outlet famous:
“Droughts and heatwaves, exacerbated by local weather change, have knocked olive oil output in Spain, the world’s largest producer, in addition to different main producing nations comparable to Italy and Greece, creating a worldwide shortfall.”
Olive bushes in Mediterranean nations develop a big portion of the world’s olive oil, with Spain alone producing greater than 40 per cent.
Satellite tv for pc photographs from NASA’s Earth Observatory, point out that Spain was “browned by drought” between the Mays of 2022 and 23. This drought “dried up reservoirs, parched olive groves and led to water restrictions throughout the nation”, NASA stated.
Spain noticed record-breaking temperatures throughout virtually half of the nation in 2022, in response to a 2023 research. The researchers famous that “regardless of regular rainfall circumstances, the extraordinarily excessive temperatures led to intense drought circumstances in most areas”.
The olive crop in Spain has proven indicators of enchancment since 2022.
Officers stated manufacturing reached greater than 850,000 tonnes in 2023-24. That is nonetheless “considerably under the five-year common”, however 28 per cent increased than the “traditionally poor harvest” of 2022-23, the Olive Oil Instances reported.
China
Climate extremes decrease rice yield

China is a serious producer of cereals – rising extra rice and wheat than another nation on this planet.
The chart above, based mostly on the findings of a 2023 research, exhibits that excessive rainfall lower rice yields in China by round 8 per cent from 1999-2012.
The researchers analysed long-term nationwide observations and mannequin simulations, each displaying comparable outcomes on the influence of maximum rainfall on rice yields.
Warmth, drought, chilly and different types of excessive climate additionally negatively impacted rice yields throughout this time, the chart exhibits.
Separate authorities knowledge exhibits that rice manufacturing fell by 3 per cent between 2018 and 2023. Wheat rose by virtually 4 per cent and corn by virtually 12 per cent throughout this time.
A 2018 report from China’s Ministry of Ecology and Setting outlined that local weather change has “considerably impacted cropping methods”. Local weather change will carry much less dependable rains, improve the unfold of harmful pests and lead to shorter rising seasons for a lot of crops in China, the report added.
China has been hit by a deluge of excessive temperatures, floods, drought and different types of excessive climate over the previous few years.
July 2024 was China’s hottest month since complete data started in 1961, in response to Reuters. The nation has additionally confronted 25 large-scale floods thus far this 12 months, the state-supporting World Instances stated, which is the very best since data started in 1998.
This 12 months, farmers in Henan province – China’s jap “agricultural heartland” – have been coping with “parched crops” adopted by excessive rainfall only one month later, CNN reported. The outlet stated:
“Elements of Henan’s hardest-hit Nanyang metropolis noticed greater than 600 millimetres (about 24 inches) of rain in 24 hours – three-quarters of what they’d usually count on in an entire 12 months.”
Drier soils will not be capable of soak up water as shortly as moist ones, so intense rainfall after a interval of drought can result in water working off the floor of the soil and inflicting floods.
The price of some vegetables and fruit, comparable to cabbage, spinach and pears, has “risen sharply” in China since June, Reuters lately reported, after floods and warmth that “devastated hundreds of thousands of acres of farmland and is now hitting customers of their pockets”.
Final 12 months, Carbon Transient reported on the influence local weather change is having on China’s cropland. Extreme drought adopted by heavy rains and floods final summer time destroyed corn, rice and wheat crops across the nation.
