Of particular concern is the inability to predict how rainfall across the globe may change in intensity, frequency and seasonality.

Water is necessary in the production of virtually all types of…

Water – a Human Right?
In the world, over one billion people live without access to clean water resources. These people have extremely large death rates to completely preventable, waterborne illnesses. It is estimated that over two million people die every year from preventable waterborne diseases, and a large percentage of those people are children under the age of five.…

Gridlock in Everglades Land Deal
For many who have been following the saga of the Everglades of South Florida, it seemed that restoration and conservation plans formed during the last decade were only getting more complicated and mired in bureaucracy.
