Palmer Drought Severity Index
CDC releases drought indices computed by county and month
The Centers for Disease Control has released ready-to-use drought datasets: The Palmer Drought Severity Index, the Standard Precipitation Index, and the Standard Precipitation and Evaportranspiration Index, computed for each county in the country by month, from 2000 to present. The U.S. Drought Monitor is available for each county at weekly intervals. Aggregating data from many different observation stations to county level is a considerable undertaking, and having this data readily available makes drought-related analyses much easier to perform. Access it here.

Nature Conservancy touts precision agriculture

David Cleary, with The Nature Conservancy, calls precision agriculture the game-changer for conservation efforts tied to ag. Smart technology has enabled farmers to maximize their crop yields while simultaneously reducing their water and fertilizer use. "Conservation benefits come as a collateral benefit," he writes, "but one which we should take note of." Read more here.
