I think highly of growing food vegetables in such way, using any of the land available for it, and for subsistence it can be very much more sustainable.

1. We are not going to be able to grow enough food; and the food we are going to be able to grow is going to be increasingly less nutritious as we deplete our top soil.
2. This will not solve other problems of overpopulation, such as the water shortage, which is far more immanent.
Is this to suggest that we can't possibly do enough to solve things, so we shouldn't bother doing anything which we can do for betterment? That is not good to think. Every individual's full efforts to contribution to betterment will matter, that shouldn't be dismissed, anymore than an individual's vote, which would matter less than that.
"We are not going to be able to grow enough food."
If that is so, it is most certain with us depending on animal agriculture, which takes most of the land, water, and resources, instead of using it all for simply growing what we can have for food and materials directly which would be more immediately available and be much more efficient in providing those, not to mention would contribute to what would be a much more healthy way that people can eat.
"food we are going to be able to grow is going to be increasingly less nutritious as we deplete our top soil."
Issues with growing crops can be dealt with in a number of ways, including strategies that vary from monocultures. Animal agriculture on the other hand is increasingly producing what is unhealthier for us, and it does not eliminate such problems.
"This will not solve other problems of overpopulation, such as the water shortage, which is far more immanent."
Simply growing what we can have for food and materials instead of depending on animal agriculture would contribute less to problems of overpopulation, and about water available for use, far far more water is used to keep animal agriculture going than would be used otherwise, that is the significant reality.

God provides. ... faith to do His Way, and let Him work out the details is better than any climate change plan for the CO2 exhalers.
As is noted, there are conditions, and rather than depending on Yahweh providing, no matter what we do, it is called for us to live in much more responsible ways, with godliness after repentance to our wrong ways, with obedience in what Yahweh calls for us to do.
