Water quality and the biogeochemical engine

This course is an introduction to environmental sciences. Using only basic knowledge from inorganic chemistry and biology, the course will lead you to an exploration of every day issues around the world. We will tackle some basic questions: Why did the “dust bowl” or the Assouan River dam have so profound an impact on soil fertility? How do we explain the mass poisoning affecting tens of millions of people in SE Asian deltas? Why is nitrate, but not potassium, a pollutant linked to agriculture even through NPK fertilizers are used? Besides plants, are there other photosynthetic organisms? Can we reconstruct water quality from centuries ago although no water samples remain? Are biofuel or coal gasification plants viable energy solutions? Why does deforestation result in loss of fertility in the Amazon basin but not in temperate Europe? What critical water issues will be raised by megacities, which will soon represent 2/3 of the world’s population? How has the relationship between humans and water changed over the centuries?
