Increasingly, water managers are turning to satellites like Landsat to monitor inland waters.
High levels of residential abandonment and unchecked vegetation growth in low-income neighborhoods are strong indicators of mosquito prevalence. Higher income neighborhoods are also susceptible to mosquito-borne disease due to the presence of irrigated vegetation, which creates mosquito-friendly habitat.
With the growing frequency and magnitude of toxic freshwater algal blooms becoming an increasingly worrisome public health concern, Carnegie scientists Jeff Ho and Anna Michalak, along with colleagues, have made new advances in understanding the drivers behind Lake Erie blooms and their implications for lake restoration.

We recently spoke with veterinary epidemiologist Todd Kelman from the University of Davis, California about his avian flu research. Todd has incorporated Landsat data into his research and we wanted to know more.
When a Los Angeles water treatment plant had to discharge treated water closer to shore than usual in the fall of 2015 due to repair work, NASA satellite observations helped scientists from the City of Los Angeles and local research institutions monitor the Santa Monica Bay for any impacts. For the city, it was an opportunity to assess the use of satellites in guiding a substantial monitoring effort. For NASA, it was an opportunity to refine the use of satellite assets to study a coastal environment.
When global food prices spiked dramatically in late 2007 and into 2008, the costs of many basic dietary staples doubled or even tripled around the world, sparking protests and riots. Panicked governments stopped exporting food, aggravating the crisis.
Naga Manohar Velpuri, works with the USGS Famine Early Warning Systems Network (FEWS NET). The project has recently initiated a large-scale project to monitor surface water bodies in the pastoral regions of Africa using multi-source satellite data and hydrologic modeling techniques. Currently, a total of 293 water points are being monitored in 10 countries. Velpuri shared some of the projects findings he presented at #AGU15.
