At the Brown Environmental Leadership Lab, high school students learn the skills they need to create change on environmental issues facing their local communities and the planet as a whole.

If the world turns to intensive farming in the tropics to meet food demand, it will require vast amounts of phosphorus fertilizer produced from Earth’s finite, irreplaceable phosphate rock deposits, a new analysis shows.

Two environmental science concentrators in the Institute at Brown for Environment and Society have won an international prize for their idea to make Kenyan fish farming more sustainable.

Cropland recycles less water into the atmosphere than native vegetation in Brazil’s wooded savannas, which could lead to less rain in the region as agriculture expands.

Studies of how climate change might affect agriculture generally look only at crop yields. But climate change may also influence how much land people choose to farm and the number of crops they plant each growing season. A new study takes all of these variables into account, and suggests researchers may be underestimating the total effect of climate change on the world’s food supply.
