Sep 7, 2017Finding Baltimore’s Mosquito Hotspots with Help from Landsat

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.

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.

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.

For those who live along its shores, Lake Tanganyika in east Africa is the backbone of local transportation and serves as an essential source of household water and protein. Every night, fishers lure nocturnal, sardine-like fish called dagaa with compression lamps that are strung between their boats. From the shore, the lake sparkles with the lights of miniature moons as people gather the treasured catch.

Jan 26, 2015Water Mapping Technology Rebuilds Lives in Arid Regions

Turkana County in northwest Kenya has been reeling from several years of crippling drought. As a consequence, the nomadic peoples in the region have suffered. Livestock such as goats and cattle, the sole source of income for these pastoralists, have perished by the droves from starvation, and the resulting economic hardship has left many children malnourished. Many have also died from violent clashes over increasingly scarce resources.

Earlier this year, I attended a workshop in Arusha, Tanzania to train research scientists from South Africa, Ivory Coast, Mauritania, Botswana, Kenya and Tanzania on how to use products derived from NASA satellites to monitor climate and environmental factors that influence the transmission of vector-borne diseases such as malaria, leishmaniasis, trypanosomiasis, schistosomiasis and Rift Valley Fever. Together, these diseases represent a scourge to both humans and animals in the region, affecting millions in East Africa alone.

Oct 30, 2013Using Landsat to Detect Human Rights Violations

Over 2500 villages were destroyed during six years of conflict in Darfur between 2002 and 2008. Dr. Andrew Marx, a 2013 fellow at the Center for the Prevention of Genocide at the U.S. Holocaust Memorial Museum, has found that this type of destruction—associated with human rights violations—can be detected using freely available Landsat data.
