That's not how the State of Texas looks at it. For arable, timber and livestock land, they (and the counties) make a clear distinction between 'production' and 'consumption'. (The other category is 'investment' land)
Any land used for your own ag use is consumption. Doesn't matter if you are 100% food self sustaining (you grow ALL your own food) it's still not 'production'.
I wish our county would follow those rules closer. Dang near anyone that lives in the county and has more than an acre gets an ag exemption. I think this is the reason the county is broke. Also people looking to move see the low tax rate and think it's a bargain. The state actually came down on the county a few years back and raised the taxes some but I doubt they have the man power to ever go through everything and get it right.
Last several times I've been to Texas I was shocked by how much "development" had blown up out in the countryside. I saw this trend developing already when I first visited about 40 years ago, but it's been stepped up dramatically in the last 15, from what I can tell. Seems like there's almost no "countryside" actually left in NE TX... used to be mostly beef, dairy and hay operations, now mostly "ranchettes" and housing developments around every corner.
Is that what you there all WANT, or is it just being forced onto you, with little you can do about it? I mean, I can see that if you have some land out in the country and it's not "making it" financially with farming, then you have to turn to the next option, which might just be selling it for development if that's how it's going around you anyway... and then I can see how you wouldn't want the laws changes so that you CAN'T do that... I mean, that might be your only means to come out ahead in the end.
But you know what that means then too... all they have to do is create that situation (where you can't make ag land pay with ag operations), and even the ranchers/farmers that have land will vehemently oppose any regulatory (laws/ordinances/zoning) attempt to prevent encroachment into ag property by the developments.... because it erodes away their "property value".
I kind of had already given up on most of the stuff east of the Mississippi years ago, because of how "overpopulated" the rural areas were quickly becoming. I just don't care to cross that river anymore at all unless I have to. Too much traffic, too much development, not "rural agricultural enough" anymore for me to enjoy it. I keep saying that I like Wyoming/Montana... but the west coast money is discovering them too now. Much as I hate the idea of more regulation, I'm beginning to become convinced that it's the only way that we'll be able to preserve ag land into the future from "development potential".
Scary thought to consider that our food supply might not be able to be "self-sustaining"... NOT because we don't know how to grow food..., but because we won't be ALLOWED to grow food, because everybody instead wants to put houses and strip malls on all the ag land. There won't be enough "ag protected land" left, at the rate we're gobbling it up willy nilly.
And what does it mean to be "ag protected"? To me, that means that we are going to protect this "ag land" from every OTHER kind of potential use... FOR AND IN FAVOR OF AG. So then how is it that you can't put a "hog setup" or "feedlot" on ag protected land in an ag protection district, simply because there's a house within a half mile? Doesn't make any sense to me. Don't get me wrong... I get that nobody wants to live right next to a feedlot, for example... and if you built your house out there, and then a feedlot is proposed next door, I get that wouldn't sit too well with that homeowner... even if that homeowner was me. But THAT IS what is done in ag areas, like it or not. And you should realize that THAT is the kind of thing that can and will happen in that area... It WON'T happen in an area zoned "residential". If you want your home protected from ag impacts, then DON'T build your home, and don't BUY a home, in an ag disctict, PERIOD.
I'm tired of arguments and ordinances that are intended/designed to try to protect RESIDENCES from perceived negative agricultural impacts in an ag protection district.
