That doesn't seem to be much of a thing these days. If you look at Russia/Ukraine or China/Taiwan there's not much scarcity. It's more bullying dictator wants to control the neighbours issues.

There's a terrifying amount of food insecurity and poverty in Russia - https://www.globalhungerindex.org/russia.html - https://databankfiles.worldbank.org/public/ddpext_download/p...
At any given time approximately 1 in 10 humans are facing starvation or severe food insecurity.
"Global warming may not have caused the Arab Spring, but it may have made it come earlier... In 2010, droughts in Russia, Ukraine, China and Argentina and torrential storms in Canada, Australia and Brazil considerably diminished global crops, driving commodity prices up. The region was already dealing with internal sociopolitical, economic and climatic tensions, and the 2010 global food crisis helped drive it over the edge."

If you ignore Gaza and whole of Africa, maybe.
It will be, or, it's slowly happening already. Climate change is triggering water and food shortages, both abroad and on your doorstep (California wildfires), which in turn trigger mass migrations. If a richer and/or more militarily equipped country decides they want another country's resources to survive, we'll see wars erupt everywhere.
Then again, it's more of a logistics challenge, and if e.g. California were to invade Canada for its water supply, how are they going to get it all the way down there?
I can see it happening in Africa though, a long string of countries rely on the Nile, but large hydropower dams built in Sudan and Ethiopia are reducing the water flow, which Egypt is really not happy about as it's costing them water supply and irrigated land. I wouldn't be surprised if Egypt and its allies declares war on those countries and aims to have the dams broken. Then again, that's been going on for some years now and nothing has happened yet as far as I'm aware.
