A new study suggests Oregon's land use planning program has largely protected farm and forest operations while promoting scenic views, water quality, and environmental amenities. However, it has also enabled the growth of 'hobby farms' that may not prioritize agricultural production, but still contribute to rural beauty and job creation.
Researchers used computational modeling to simulate different land use practices in ancient societies, finding that a combination of shifting cultivation and grazing leads to more erosion runoff but also fertile farmland around tiny hamlets. The study sheds light on the importance of threshold effects when people alter landscapes for a...
