Ecological Services (PES) and

incorporation of ecological

accounting in the budget

- Commitment of city managers for

Urban Systems with Ecological

Security (USES)

- Effective interlinked policy

framework for national, regional

and local environment quality

- Committed trained man-power

for monitoring and controlling

environmental aberrations of

developmental projects

Technological Nuances

Best Available Technology (BAT)

- approachable technology effective in preventing or minimizing pollution emissions

Best Available Technology Not Entailing Excessive Costs (BATNEEC) - focus explicitly on cost – benefit analysis i. e. financial costs should not be

excessive as compared to the financial capacity of the stakeholder

Best Environmental Practices (BEP)

- curtail the transferring of pollution from one phase to another

Best Practical Environmental Option (BPEO)

- identification the least environmentally damaging method for the discharge of

pollutants

Suitably Applicable and Affordable Technology (SAAT)

- consideration of local site specific conditions, skill levels of personnel, availability

of materials, equipment, energy and extent of pollution

“Ecotechnology is an applied science that seeks to fulfill human needs

while causing minimal ecological disruption, by harnessing and subtly

manipulating natural forces to leverage their beneficial effects. “

- Wikipedia

What is Ecotechnology?

Ecotechnology for pollution treatment is an application of ecological

processes for the resources and waste management using combinations

of aquatic or terrestrial plants, microbes, invertebrates, vertebrates and

subtly manipulating natural forces to leverage their beneficial effects

through maneuvering cycling of matter and energy . “

Epilogue

Conventional wisdom has traditionally regarded the modern city

as the product of cheap energy, economic forces, high

technology and a view of nature that is under control. The

underlying disciplines that have shaped the city have little to dowith the natural sciences or ecological values.

- “Cities & Natural Process” by Michael Hough
