Urban expansion, at least in the few areas where Iowa cities are growing, is eating up some of the state’s best farmland. The urban growth is part of a national trend in which good farmland is lost to new residential neighborhoods.
America has lost millions of acres of farmland over the nearly three decades to urban and rural development. Despite conservation efforts by state and local governments and increased financial incentives for farmers, urban development and the expansion of rural residential real estate over the last 25 years has eliminated farmland across the country at levels not seen since the early 1970s.
