>Disease and climate issues have also affected most of the world's top citrus-producing countries

What evidence is there for this? The author goes on to not cite anything from the US and actually gives an example from Brazil that uses faulty logic, making the common mistake of confusing whether with climate.

I live in Asia and have seen first hand how production in China has gone up over the years, not down. This can also be proven in numbers.¹ ² China happens to be the world's top producing country btw. So what does Freida Frisaro know that the USDA Foreign Agricultural Service, private analysts and traders, as well as people living in China don't know? Does "climate change" only happen in Western countries?

Quote:

> "After several years of consistent growth[!], China’s citrus production in MY 2023/24 is expected to continue to climb and will remain the largest fruit category, outperforming other fruits (i.e., apples). With favorable weather and the recovering acreage from earlier greening disease, all citrus crops – oranges, tangerines, mandarins, grapefruits, pomelos – are expected to have strong yields. Although consumers are increasingly price conscious, demand is expected to remain strong. Incremental changes in trade flows are anticipated, as China continues to promote regional trade."²

According to this article from 2020 https://m.thepaper.cn/newsDetail_forward_10041777 citrus greening caused direct economic damage upwards of 10 billion RMB per year (more than US$ 1 billion).

Professor He Yujian, profiled in the article, recently published about his approach to combating the disease https://link.springer.com/article/10.1007/s10658-024-02835-y which seems to be producing good results.


I don't understand your line of reasoning here.

"Asia is growing more citrus, so if a state in the US is growing less citrus, a global phenomenon can't be a contributor"?

Did I get that right?


The decrease in production in Florida could be due to climate change. It could also not be. I'm pointing out that the article provides no proof and am asking what evidence there is.

Using the same logic the author used and applying it to the USDA report, do you then believe climate change has lead to an increase in production in China? Would you welcome articles praising climate change for giving us more Chinese citrus?


> Using the same logic the author used and applying it to the USDA report, do you then believe climate change has lead to an increase in production in China

That may or may not be the case. Climate change is not homogeneous, and affects different regions differently. Even if it were homogeneous, there are plenty of places on earth that would benefit, agriculturally, from a warmer climate. I dont know whether or not portions of China fall in that category.

That being said, I think the longer summers are exacerbating the problem with the disease that is the core driver of collapse of citrus in Florida, but climate change itself is probably not a direct contributor.


Citrus fruit are native to Southern China, it's fair to assume they are adopted to the climate here. "Summers" are almost the entire year with the exception of maybe three months when it gets cooler. It's subtropical climate. I have not been to Florida but Wikipedia describes it as "humid subtropical", which would be exactly identical to places like Guangdong.

>Climate change is not homogeneous, and affects different regions differently.

That's true. So has it gotten cooler or hotter in Southern China over recent decades? We should look at that: Temperatures have increased here also. So what leads to an increase in production in one place leads to a collapse in the other? All I'm asking is have you considered the possibility that it may not be related to climate at all, not even indirectly? Because disease can be caused by other factors, if that's the actual culprit. Another user has suggested simple economics, which is more often the real cause for abandoned farms.


> So what leads to an increase in production in one place leads to a collapse in the other?

As noted, the disease benefits from warmer weather. Plants probably do as well, but that's moot when a disease is killing them.
