The main theme of ESES 2012 will be "Socio-economic indicators of climate change, Impacts of climate change on natural resources (flora and fauna) and Water quality issues and sustainability of water reuse". Papers on all aspects of environmental sciences will be welcome as well. This conference will offer outstanding international speakers. There will be time for abstracts, posters, and many informal discussions that have helped make past meetings successful. We are confident that every participant's intellectual pursuits will be fully satisfied with the scientific program, field excursions and social events that we are planning.
