bio eco engineering

  1. 1. Bio-eco Engineering Biological Ecological Engineering
  2. 2. Bio-eco Engineering • is the use of engineering solutions, which improves traditional structures using natural resources to increase the structure functionality, or the use of natural materials (flora and fauna) to create structures.
  3. 3. Overview • it emerged as a new idea in early 1960s, but its definition has taken several decades to refine, its implementation is still undergoing adjustment, and its broader recognition as a paradigm is relevantly recent.
  4. 4. • Ecological engineering was introduced by Howard Odum and others as utilizing natural energy sources as the predominant input to manipulate and control environmental systems.
  5. 5. • Mitsch and Jorgensen wrote that ecological engineering is designing societal services such that they benefit society and nature, and later noted the design should be systems based, sustainable, and integrate society with its natural environment.
  6. 6. • Mitsch and Jørgensen were the first to define ecological engineering and provide ecological engineering principles. Later they refined the definition and increased the number of principles. They defined and characterized ecological engineering in a 1989 book and clarified it further in their 2004 book.
  7. 7. • They suggest the goal of bio-eco engineering is: the restoration of ecosystems that have been substantially disturbed by human activities such as environmental pollution or land disturbance, and
  8. 8. the development of new sustainable ecosystems that have both human and ecological values. • They summarized the five concepts key to ecological engineering as: it is based on the self-designing capacity of ecosystems,
  9. 9. it can be a field test of ecological theory, it relies on integrated system approaches, it conserves non-renewable energy, and it supports biological conservation. • Bergen et al. defined ecological engineering as: utilizing ecological science and theory,
  10. 10. applying to all types of ecosystems, adapting engineering design methods, and acknowledging a guiding value system. • Barrett (1999) offers a more literal definition of the term: "the design, construction, operation and management (that is, engineering)
  11. 11. of landscape/aquatic structures and associated plant and animal communities (that is, ecosystems) to benefit humanity and, often, nature." • Barrett continues: "other terms with equivalent or similar meanings include ecotechnology and two terms most often
  12. 12. used in the erosion control field: soil bioengineering and biotechnical engineering. • However, Eco engineering should not be confused with 'biotechnology' when describing genetic engineering at the cellular level, or 'bioengineering' meaning construction of artificial body parts.
  13. 13. • “This engineering discipline combines basic and applied science from engineering, ecology, economics, and natural sciences for the restoration and construction of aquatic and terrestrial ecosystems.
  14. 14. • The field of ecological engineering is increasing in breadth and depth as more opportunities to design and use ecosystems as interfaces between technology and environment are explored.
  15. 15. Design Guidelines • Ecological engineering design will follow a cycle similar to engineering design problem formulation (goal), problem analysis (constraints), alternative solutions search, decision among alternatives, and specification of a complete solution.
  16. 16. • Elements that distinguish ecological engineering design are elaborated by many authors, however a singular approach is still absent. • Typically, the design goal involves protecting an at-risk ecosystem, restoring a degraded ecosystem,
  17. 17. or creating a new sustainable ecosystem to satisfy needs of nature and society. • A temporal framework is provided by Matlock et al., stating the design solutions are considered in ecological time. In selecting between alternatives,
  18. 18. the design should incorporate ecological economics in design evaluation, the design should incorporate ecological economics in design evaluation and acknowledge a guiding value system which promotes biological conservation. applying to all types of ecosystems,
  19. 19. adapting engineering design methods, and Design steps should be based on utilizing ecological science and theory, the self-designing capacity of ecosystems; accept the adaptive management theory of learning from mistakes as the design will field test ecological theory;
  20. 20. utilize integrated system approaches; and conserve non-renewable energy.
