| Abstract | Minerals found in coastal sand dunes, beaches, near shore, and throughout a nation’s exclusive economic zone are important assets that contribute to national blue economies. Extracting minerals in a manner that adheres to blue economy principles can be challenging because of the difficulties in mining minerals in environmentally and socially sustainable ways. The positive effects of extraction need to be finely balanced with negative effects on other blue economy resources, such as fisheries and tourism. Yet, we cannot ignore mineral extraction in a book on blue economy because several countries include minerals in their blue economy plans. Scientific knowledge and modern technology that are necessary as foundations to achieve sustainable extraction may be lacking in the mineral resource development plans of many nations. This chapter discusses two primary types of mineral extraction: (1) heavy minerals and diamonds that are carried by fluvial means into coastal areas where they form deposits by natural physical processes and (2) phosphate minerals that are formed in place through natural chemical processes in some coastal areas of the world. The chapter will describe environmental and social implications of mineral recovery, including ways by which these resources can play an important role in blue economies. |
