Forty percent of the farmland in Treasure Valley has been lost to development over the last 40 years.

And a new study by Boise State University shows that 110,000 to 240,000 more acres in the valley will be lost to development in the coming decades.

Now a recent poll for Idaho Politics Weekly finds that three-fourths of all Idahoans are concerned about so much farmland coming out of production and being turned into subdivisions and commercial space.

Pollster Dan Jones & Associates finds:

-- 75 percent of Idahoans are “very” or “somewhat” concerned about the loss of farmland and the accompanying urban sprawl.

-- 23 percent are not worried about it.

-- And 2 percent don’t know.

Politically speaking, there is not much difference in the opinions of Republicans, Democrats and independents on this subject:

-- Republicans are concerned about the loss of farmland, 72-26 percent.

-- Democrats, 76-23 percent.

-- And political independents, 79-21 percent.

But there is a difference in one area – education.

Jones finds that those with only a high school education are concerned about farmland loss, 77-20 percent.

While those with a graduate degree from a university or college – like a Masters, PhD, or law degree – are less concerned about farmland loss, 63-37 percent.

Jones polled 619 adults from November 8-15. The survey has a margin of error of plus or minus 3.94 percent.
