High-tech tools help us better understand natural and human-managed ecosystems. —Troy Magney

When I began working with REACCH last year, it was interesting that no matter where I went or who I spoke to, the topic of precision agriculture came up. Not only were researchers studying it but farmers were using it, professors were teaching it, regional businesses were selling software and equipment, and conservation organizations were promoting and funding it. So exactly what is precision agriculture and why is everyone so interested?

REACCH scientist John Abatzoglou explains why July and August were so hot.

Aside from a few locations in mid-latitudes, July and August are the warmest months of the year. However, the northwestern US experienced extraordinary warmth over the past 6-8 weeks with most locations 2-3 degrees C (3-5 F) above normal adding to the crescendo of the hottest time of the year.

If we go back in time twelve thousand years from the present, to a period marking the formation of the Puget Sound within the Pacific Northwest (PNW) region of North America, we see geo-climatic conditions drastically different from those predominating on Earth today. With one half of Earth's surface covered in ice, extensive glaciation  drove massive landscape alteration and mass extinction of biota. This glaciation progressed via a feedback loop of changing abiotic forces,including drastic reductions of mean global temperature.

Agriculture has been relied upon as a food source for humans for thousands of years. For much of that time, wheat has been one of the most important crops that people have grown. Wheat, like most crops, is reliant upon certain quantities of water to grow properly.
