Thwarting the spread of deadly bacteria- To stop the spread of hard-to-treat infections, hospitals are sending weekly emails to hospital leaders that include an update on the number of cases and a ranking of unit performance as well as an action plan.
Water resource protection using buffers, setbacks and swales to reduce or prevent the transport of sediments and nutrients from production areas to water bodies.
Irrigation management to address the method and scheduling of irrigation to reduce water and nutrient losses to the environment.
