It still sounds like transparent governance of community-funded farms would enable you to address the biodiversity of your region. Having an efficient farm doesn't mean you have to crank the efficiency dial to the maximum. But inefficiencies are paid with the fact that fewer people can access the ecological lifestyle we're talking about, whereas a community farm will allow someone who doesn't have a garden to pursue an ecological lifestyle.
Furthermore, a community governing a farm can centrally plan out for ecological concerns, and they can actually measure and study their progress. A decentralised community is hoping the winds of fortune will coordinate them. A lot of this comes down to whether you trust the ability of a community to maintain control.
Also I know people who have a well-sized garden meant to actually make produce, but nobody would say it could remotely alleviate their food or lifestyle burdens. The time-sink is huge; they do it for the gratification of home gardening, not as a mitigation of food burden.
