Environmental statistics is in a take-off stage both for reasons of societal challenge and statistical opportunity. Environmental statistics is increasingly demanding non-traditional and innovative statistical approaches. This is partly because, unlike in many hard sciences, environmental studies involve space, time, and locally ingenious environmental sampling and monitoring. Also, environmental statistics must satisfy environmental policy research in addition to disciplinary and interdisciplinary environmental research. The chapters written by several outstanding professionals involved in statistics and the environment discuss the current state of the art in different areas of environmental statistics and provide new perspectives and problems for future research, training, policy, and regulation involving statistics and the environment.
