          By its nature, mining drastically
        
        
          disturbs the land. While progressive
        
        
          reclamation is common at almost all
        
        
          mines, the environmental legacy of
        
        
          natural resource extraction continues
        
        
          to pose political, social, and legal
        
        
          challenges, and the current state of
        
        
          practice seldom results in full reclama-
        
        
          tion after closure. In recent decades,
        
        
          the need for mine owners and society
        
        
          to improve how they work together
        
        
          to ensure mine lands are made safe
        
        
          and useful has become increasingly
        
        
          apparent.
        
        
          Helping practitioners build sustainable
        
        
          mining landscapes is the objective of
        
        
          the new non-profit Landform Design
        
        
          Institute, which was introduced in
        
        
          September to a receptive audience
        
        
          of reclamation specialists at the 42

            What is landform design?
          
        
        
          Landform design is an emerging
        
        
          process used to successfully recon-
        
        
          struct mine land. It allows industry,
        
        
          regulators, and communities to work
        
        
          together to manage costs and risks,
        
        
          minimize liability, and produce
        
        
          progressively reclaimed landscapes
        
        
          with confidence and pride. Land-
        
        
          form design embraces conventional
        
        
          reclamation but is broadly focused. It
        
        
          starts before mining begins in order to
        
        
          provide design, construction support,
        
        
          and stewardship throughout the life of
        
        
          the mine and beyond.
        
        
          Landform design operates at the
        
        
          element, landform, landscape (mine
        
        
          site), and regional scales. Typical
        
        
          mining landforms include waste-rock
        
        
          dumps, mined-out pits, tailings stor-
        
        
          age facilities, and the surface-water
        
        
          drainage system. Design teams include
        
        
          planners, engineers, geologists,
        
        
          hydrologists, geochemists, keepers of
        
        
          traditional knowledge, ecologists, and
        
        
          operations and reclamation specialists.
        
        
          They start with a design-basis memo-
        
        
          randum that sets out agreed upon
        
        
          goals, objectives, and design criteria
        
        
          for each landform and landscape.
        
        
          This living contract evolves over the
        
        
          decades between the initial vision and
        
        
          final signoff.
        
        
          
            Why an Institute?
          
        
        
          The Institute’s goal is to make land-
        
        
          form design common in the mining
        
        
          industry by 2030. It’s dedicated to
        
        
          creating and supporting a community
        
        
          of landform design practitioners. It
        
        
          will help teams design and build truly
        
        
          sustainable reclaimed lands by provid-
        
        
          ing the practical “how to” of landform
        
        
          
            Landform design operates at the element, landform, landscape (mine site) and regional scales.
