“I got kind of sick of working on environmental problems, and I wanted to work on environmental solutions. From that standpoint, agriculture — it’s like the world is your oyster. There’s so much that could be done.”
Lisa Schulte Moore, an professor of natural resource ecology and management at Iowa State University, seems to have the energy of three people. She has a hand in agricultural landscape management, bioenergy development, oak restoration, and hemlock and pine forest management, among other projects, and still makes time to drive all over Iowa, talking to farmers. In this episode of Field Talk, she explains how integrating STRIPs of prairie into conventional row crops improves water quality — and helps farms, waterways, and wildlife.
This is the first in a series of conversations springing from ideas and arguments about “land-sparing” and “land-sharing” strategies to conserve a rich tapestry of species in our human dominated world. Should we intensively farm some lands in order to preserve wildness in reserves? Accept a more flexible, less “pure,” idea of wildness, embracing conservation easements threaded into more diversified agricultural landscapes? Is this dichotomy a useful concept at all?
