[DCHAS-L] sustainability definition
"meeting the needs of the 
present without compromising the ability of future generations to meet 
their own needs." 
Its a well accepted and also a well critiqued 
definition for sustainable development. 
The 
definition, quoted by the Thacher government, takes a 'vague approach' 
by including  
inestimable  
words like 'needs' or 'future'. However the ambiguity is 
intentional to leave room for flexibility and scope for custom-made 
context responsive solutions.  
The concept of sustainability is a proponent of  versatility aimed at 
longevity of a process or a product. Nevertheless, at all times it 
speaks of a holistic approach considering the three spheres of ecology, 
society and economics.
Again, 
the definition is useful to initiate thought and accumulate quantity of 
believers, however is fatal to the concept of sustainability once it 
comes to the practical application. Due to the intended ambiguity, the 
concept can be interpreted in in numerous ways, some of which may be 
actually counter-productive.
Few 
principles, as quoted by Kyoto protocol, are of use 
here:
Precautionary Principle, 
that is, do not practice something which is known to be counter 
productive towards the goal of sustainability
Equity, that is across generations, and across 
nations.
Sustainability may have been in practice since many 
decades at different levels and with varying degrees of vigor. 
Currently, due to the urgency of climate change, the one crucial aim of 
practicing sustainability is to reduce carbon footprint of any act, 
process or product. As critical the aim is, sustainable development is a 
much wider and idealistic concept which may seem to be failing under the 
financial, fuel and food crisis of the contemporary world. The theory is 
not only about a technological fix, say photovoltaic cells, or of a 
social improvement, say grass root level approach, or of conserving 
biodiversity. The theory of sustainable development encompasses all. To 
practice the right approach at the right place, in the right time; while 
being aware of the larger level issues and intentionally responding to 
the context is a step towards sustainable development.
