Landsat Images Advance Watershed Restoration in Western Tanzania

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.

Water 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.

Field Notes: Climate, Health and the Maasai

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.

Using 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.

Vast Water Reserves Found in Drought-Prone Northern Kenya

Large underground water reserves have been found in Turkana, one of Kenya’s driest and poorest regions. The discoveries were made by the natural resources exploration firm, Radar Technologies International, during the course of a survey of groundwater conducted for the Kenyan Government on behalf of the UN. The aquifers were detected with the WATEX System, RTI’s state-of-the-art, space-based exploration technology.

Environmental Monitoring with Public Domain Satellites

WNYC’s Leonard Lopate talks with SkyTruth president, John Amos, about using public domain satellite imagery, such as Landsat, to monitor the environment. SkyTruth uses all types of satellite imagery to monitor environmental changes and disasters; Landsat is prominently mentioned among them.

Using Landsat 8 to Locate Fires in Indonesia

In June, air pollution over Singapore and Malaysia spiked as forests in neighboring Sumatra (Indonesia) burned. Using NASA’s daily fire alerts and official national maps, the fires were located in the vicinity of oil palm and acacia tree plantations. However, the coarse resolution of the fire alerts coupled with outdated national maps, made it hard to establish culpability.

What is the Economic Value of Satellite Imagery?

Does remote-sensing information, such as that from Landsat and similar Earth-observing satellites, provide economic benefits to society, and can this value be estimated? Using satellite data for northeastern Iowa, U.S. Geological Survey scientists modeled the relations among land uses, agricultural production, and dynamic nitrate (NO3) contamination of aquifers.
