Negative Feedbacks

2Technology a Two-Edged Sword
- Technology deals with the societys knowledge of
and relationship with its tools and crafts - Human progress through ages driven by technology
- Technology used to control and manipulate the
environment - Harmful by-products leading to pollution and
degradation of environment
3Level of technology adds a very critical
dimension to man-nature relationships Diverse
interpretations of technology by technologists,
technocrats and technophiles, philosophers,
environmental scientists, economists, deep
ecologists and others Martin Heidegger
technology as revealing that brings forth
what is yet unrevealed Appropriate Technology
of ecologists e.g., solar energy In contrast,
modern technology an agent of Enframing Challe
nges Nature as a Standing Reserve, excluding
all other possibilities that Nature may have
4- Heideggers interpretation of a dam on River
Rhine loss of autonomy and enframing - Schumacher emphasis on small-scale technology
more revealing than challenging, e.g., micro
hydel technology - A solar panel or wind-energy generators as
opposed to thermal or nuclear power plants - Nature losing its autonomy when treated as a
standing reserve - And an essential fallout is pollution
- Thus nature is enframed and even enslaved
- Made to perform at the will of man
5Nature is transformed into an object that is
meant to be processed through technology Nature
to be conquered not understood and for
harvesting and not sustaining life Not
engaged in a dialogue Nature having extrinsic
or instrumental value Bubers I-It relationship
with Nature Nature as a Resource in the words
of many ecologists Wim Zweers humans as
Despots or Enlightened Rulers or compromising
(and condescending too) Stewards
6- Why technology is mostly at cross-purposes with
nature? - Technological thinking guided only by positive
feedbacks - A system guided only by positive feedbacks cannot
function as a self-regulated cybernetic system - The system needs to be equipped with negative
feedbacks - Negative feedbacks can achieve control (often
referred to as balance of nature)
7Examples of Negative Feedbacks in nature
- Predator-prey interactions each keeping the
other in a sustainable state - A small hymenopteran parasite can keep the number
of grasshoppers in check, thereby maintaining the
grass populations in a grassland ecosystem - The regulator has a minute proportion of the
total biomass and represents lt 1 of the energy
flow through the system

9Human systems have been overemphasizing positive
feedback and increased production
- Frontier Attitude
- Following r strategy instead of k strategy
- Emphasis on unrestricted growth
- Refusal to accept boundary conditions
- Characteristic of young, unstable systems
10Our dissatisfaction with/the failure of a given
technology gives rise to a new technology to
achieve unbridled growth
11Sustainable Development Calls for New Strategy
and Ethics of Technology and Development
12Ethics and Strategy need to be integrated into
each other
- When our strategies and policies are intertwined
with ethics, only then shall we have respect for
negative feedbacks - Learning to accept to operate within boundary
conditions with prudence - A paradigm-shift of technology from linear to
closed-loop systems - Industrial Ecosystems
- A balance of positive and negative feedbacks
13- Biotechnology and Nanotechnology has the
capability to alter the structural and functional
basis of both living and non-living materials - calls for a more stringent application of the
precautionary principle - Principles of Ecosystem Cybernetics with its
concepts of Positive-Negative Feedback
interactions and balance, principles of
redundancy and of keystone regulation could be of
great help in directing the future course of
technology along a safer route
