Sustainability and prosperity in the age of ecological scarcity

Contributor(s): Professor Edward B Barbier | Drawing on his book, Scarcity and Frontiers, Edward Barbier argues that how economies choose to exploit natural resources is critical to both their sustainability and prosperity. In past eras, a critical driving force behind global economic development has been the response of society to the scarcity of key natural resources. By raising the cost of exploitation and use, scarcity creates incentives to innovate and substitute. However, economies also avoid scarcity by obtaining and developing new "frontiers" of vital resources. How these two responses play out often determines which economies emerge as leaders. In the present era, rising ecological scarcity and global environmental risks are a defining turning point for all economies, but especially those that are vying to win the “green competitive race” for leading global sectors and markets. The outcome of this race will define how innovation and productivity unfolds over the coming decades as well as whether economies will become more environmentally sustainable.
