As the world population continues to grow, global demand for food could increase dramatically by 2050. Yet the impacts of climate change threaten to decrease the quantity and quality of our food supplies.
Many countries are making progress on improving water sanitation and protecting marine ecosystems. But air pollution continues as a leading health problem in many nations, and fisheries are deteriorating almost everywhere.
Human-influenced climate warming has already reduced rainfall and increased evaporation in the Mideast, worsening water shortages. Up to now, climate scientists had projected that rainfall could decline another 20 percent by 2100. But the Dead Sea cores suggest that things could become much worse, much faster.
For Mexico City’s biggest businesses and its poorest neighborhoods, rainwater harvesting could help address an enormous water crisis plaguing the city, a recent Columbia Water Center study found.
On every continent and ocean, Earth Institute field researchers are studying the dynamics of climate, geology, natural hazards, ecology and other subjects with direct applications to the challenges facing humanity.

After helping Chris an Dan with soil salinity and reflectance measurement, Humayun, Liz and I moved onto the smaller M.B. Mewl to sail through the Sundarban Mangrove Forest to service our GPS station at Hiron Point.
Despite the miserable weather and ongoing rain, we constructed a wooden structure to hold the GPS receivers, solar panels and other electronic equipment between the three wells. We worked out how and where to mount the antennas and had parts made to accomplish it. Although I had to leave before it was completed, the team persevered through the storm and now we will be monitoring ground subsidence and sediment compaction in the Mississippi Delta.

Now a new report from the group Human Rights Watch charges that the Bangladesh government “is failing to adequately respond” to the issue, and that political favoritism and neglect have corrupted the government’s efforts.
