Abstract
The impact of human activities on natural systems has grown to the point that we need to engage consciously in earth systems engineering and management. I address why this is the case, and what I mean by such a provocative term. In addition, I explore what we can learn from relevant experience, and how this daunting task should be approached. Earth systems engineering and management (ESEM) may be defined as the capability to rationally engineer and manage human technology systems and related elements of natural systems in such a way as to provide the requisite functionality while facilitating the active management of strongly coupled natural systems. The need for ESEM arises because, as a result of the industrial revolution and concomitant changes in agriculture, population levels, culture, and human systems, the world has become a human artifact. Partially because this process has occurred over time frames that are longer than individual time horizons, and has involved institutions and technology systems rather than conscious individual decisions, recognition of this phenomenon, and appropriate responses, have yet to occur. It is apparent that the science and technology, institutional, and ethical infrastructures necessary to support such a response have not yet been developed. The issue is not whether the earth will be engineered by the human species, it is whether humans will do so rationally, intelligently, and ethically.
