I'm assuming you need to find a way to make up for that. Something that's hard to do if you think about how grain is planted. Can't really drive over it with a tractor once it has a certain height. Even if you take off only the parts you need and leave the rest in place.
From a single planting, irrigated perennial rice produced grain for eight consecutive harvests over four years, averaging 6.8 Mg ha−1 harvest−1 versus the 6.7 Mg of replanted annual rice, which required additional labour and seed. Four years of cropping with perennial rice resulted in soils accumulating 0.95 Mg ha–1 yr–1 organic carbon and 0.11 Mg ha−1 yr−1 nitrogen, along with increases in soil pH (0.3–0.4) and plant-available water capacity (7.2 mm). Perennial cultivars are strongly preferred by farmers; growing them saves 58.1% of labour and 49.2% of input costs in each regrowth cycle. In 2021, perennial rice was grown on 15,333 ha by 44,752 smallholder farmers in southern China. Suited to a broad range of frost-free environments between 40° N and 40° S, perennial rice is a step change with potential to improve livelihoods, enhance soil quality and inspire research on other perennial grains.
(disclaimer that I manage a climate group, but not a rice expert) They touch on, but don't get into the details on one of the more interesting aspects of perennial rice. Rice fields are actually a huge emitter of methane. Depending on the accounting, they contribute as much to global warming as the aviation sector. The fields emit methane when flooded, the stagnant water gets oxygen depleted, and the biomass in the s…
Sounds like another premature optimization problem, as applied to climate change.

Won't yields go down eventually as the soil becomes more and more degraded as the same nutrients are extracted? I'm assuming you need to find a way to make up for that.

What about coal? You tell me, what part of fixing rice production interferes with shutting down coal mining? Because as far as anyone can tell, the answer is not a single part.

Abstract from the Nature Sustainability paper: From a single planting, irrigated perennial rice produced grain for eight consecutive harvests over four years, averaging 6.8 Mg ha−1 harvest−1 versus the 6.7 Mg of replanted annual rice, which required additional labour and seed. Four years of cropping with perennial rice resulted in soils accumulating 0.95 Mg ha–1 yr–1 organic carbon and 0.11 Mg ha−1 yr−1 nitrogen, alo…
importantly, this should reduce the need for fertilizer to replenish soil nitrogen

Germany emits 2% of all CO2, not worth us doing anything then?
Earlier quoted context omitted.

The need to eliminate coal emissions does not preclude the need to eliminate emissions from other sources.
A 100 years of coal emissions is 1000 years of rice.
