Introduction
Throughout much of history, a critical driving force behind global economic development has been the response of society to the scarcity of key natural resources, such as land, forests, fish, fossil fuels and minerals. Increasing scarcity raises the cost of exploiting existing natural resources and creates incentives in all economies to innovate and conserve. However, economies have also responded to increasing scarcity by obtaining and developing more abundant sources of natural resources. Since the agricultural transition over 12,000 years ago, this exploitation of new “frontiers” has often proved to be a pivotal human response to natural resource scarcity.
For example, before the Industrial Revolution (ca. 1775), finding and exploiting new frontiers of land and natural resources were fundamental to successful economic development and seen as an important objective of conquering and occupying new lands, monopolizing trade links, and colonizing and populating other regions of the world. However, since the Industrial Revolution and certainly over the last century, supplies of strategic raw material, mineral and energy commodities have become so cheaply available through global trade that natural resource scarcity is no longer viewed as an economic constraint. Technological applications to land, fisheries, forests and other natural resource endowments have become sufficiently productive and routine that we believe that human ingenuity and innovations can overcome any resource scarcity problem.
“If humankind is to succeed in overcoming these global problems, we need to find the next “new frontiers” of natural resources and adapt economic development accordingly.”
Today, we are on the verge of a new era, the “Age of Ecological Scarcity”. For the first time in history, fossil fuel energy and raw material use, environmental degradation and pollution may be
