In Haiti, Exploring What Drives People to Alter the Landscape

Study of the Pedernales Watershed, located along Haiti’s southern national boundary with the Dominican Republic, may provide insights into the stark contrast in land cover patterns between the two countries.

Sea Change

Gliders and buoys and robots — oh my!
Over and through the ocean they fly.
Oodles of data from sensors galore,
Studied by many, far from the sea’s roar.

Postdoc Crosses Disciplines to Put Theory to Practice

The Earth Institute postdoc has provided me with a strong foundation to continue to initiate and develop these sorts of collaborations, has helped me learn how my own research can benefit from being challenged by and contextualized in another field, and has taught me how much fun it can be to share the same sort of challenge and insight.

Bottom Up or Top Down? Another Way to Look at an Air Quality Problem

While not all countries have the financial wherewithal and capacity to deploy ground-based instruments for air-quality monitoring, and for some countries monitoring information is not available to the public, for example, through health advisories, another way exists to assess air pollution levels: through satellites.

Hybrid Climate Data for East Africa

In our latest video interview, climate scientist Tufa Dinku talks about his work on combining weather station data with satellite information to generate high-resolution data sets. These data could be used for making more accurate forecasts and can feed into other climate risk management activities, such as early-warning systems. With funding from Google.org, Dinku and… read more
