What is needed?- Evaluation of Payment of
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
- Citizens Action for Sanitation and
Health (CASH)

Biodiversity Birds increased by 8 times, dragonflies 10 times, butterflies 8
times, fish population 3 times, crabs, water monitor lizard,
snakes etc.
Green cover In water and shoreline of about 4000 sq. m
Purification of lake

Reduction in gastric diseases among the villagers who drink
the water from tube well in the lake
Awareness of
Masses
Small eatery owners started keeping waste bins; now the
wastes are not directly thrown in the lake.

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 . “

One organism’s waste is
other’s food
Secondly, the green plants
absorb carbon dioxide from
the atmosphere
Pollutants transferred to
natural cycles i. e.
biogeochemical cycles
Carbon gets stored in
vegetation and subsequently
in the soil.

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.
