"SUSTAINABLE " APPROACH IN PLANNING.

Well " SUSTAINABLE"- WORD IS NEWLY ADDED WORD IN THE DICTIONARY OF DEVELOPERS RECENTLY. I must introduce the meaning of word sustainable means " able to be maintained at a certain rate or level."  

Nowadays, fascinating buildings ,beautiful structures are winning the peoples heart; but the real approaches of the factors beside it are missing. awareness among people is actually missing ; using of resources till the usage of value added product whole chain is flowing immensely without any thought process. 

IN ALL THE SECTORS, THE LEVEL OF POLLUTION IS INCREASING" degradation of land, water and other natural features is happening. ways of doing sustainable development are adopting now a days by the cities ,because we reach the level of extinct and awareness is needed for the future generation .As Prime Minister Narendra Modi has stated, “These goals reflect our evolving understanding of the social, economic and environmental linkages that define our lives.” India’s development mantra “Sabka Saath Sabka Vikas” (Collective Effort, Inclusive Development) and the associated national programs closely track the SDGs.

ECOLOGICAL SUSTAINBILITY :

Sustainability” is normally considered to have three dimensions: economic, social and ecological. Without neglecting the other aspects of sustainability, this report will concentrate on the ecological dimension of sustainability for the following reasons: 

First, the relationship between ecological sustainability and development is crucial. Most people in the countries of the South live on the land and are therefore directly dependent on nature for their livelihood. Consequently, ecological problems in these countries rapidly become questions of survival. Second, environmental problems have assumed proportions that increasingly threaten the very survival of humankind. Among the examples that come to mind are the greenhouse effect, depletion of the ozone layer, deforestation in both tropical and temperate zones, and loss of species. Moreover, the (financial) resources available to deal with global environmental problems such as rising sea levels are limited. Although the dimensions and the urgency of these environmental hazards are widely recognized, no sufficiently effective measures are being taken to combat them.

 Third, there is a risk that the ecological dimension of sustainability will be ignored within the broader context of sustainable development, even though “sustainable development” per se was originally rooted in concern for the environment. This risk arises because economic and social changes are easier to recognize and deal with than ecological change. Furthermore, ecological issues are not given priority in times of economic difficulty. When different interests are forced to compete for scarce resources, economic and social concerns take precedence over ecological concerns. 

The distinction between renewable and non-renewable resources is an unclear one. Oil, for example, is classified as a non-renewable resource, although it is actually renewable. But the rate at which oil regenerates is so slow that it is irrelevant as human beings measure time. On the other hand, even though water is usually considered a renewable resource, some aquifers are recharged only after hundreds or thousands of years. Consequently, we can meaningfully classify a resource as renewable only if it can be expected to regenerate within a human lifetime. The difference between renewable and non-renewable resources can also be described in another way. Renewable resources, and the ways in which they are used, are inseparably linked to ecological processes. They are therefore in a state of dynamic equilibrium between renewal and utilization. If this equilibrium is destroyed, degradation occurs, and new and different ecosystems come into existence. Nonrenewable resources, on the other hand, are not an integral part of such ecological processes. They might be thought of as constituting resource pools (mineral deposits, etc.). These pools can be tapped by human beings, but they cannot be replenished. Hence non-renewable resources can actually be depleted to the point of exhaustion. Considering the distinctions between renewable and non-renewable resources raises a question about the reversibility of processes of degradation. In the case of non-renewable resources, reversibility is clearly not a factor: once oil is burned, it cannot be recreated from the combustion residue. But when renewable resources are affected by degradation, there is a chance that the process can be reversed. For example, conservation measures might be implemented to halt soil erosion. Yet once a certain threshold has been exceeded, even degradation of renewable resources can no longer be reversed.

PROMOTING PUBLIC PARTICIPATION:  

Supporting public discourse is the key element in strategies concerned with sustainable use of natural resources. Processes of public discourse should focus in particular on examining both the different functions of natural resources (productive, sociocultural and physical functions) and their various potential uses. The specific tasks of development organizations will vary according to country or region, depending on ecological and political circumstances. In principle, it should be assumed that development organizations play a supportive role designed to stimulate and further processes of open discussion. They should be prepared to mediate among different groups in an appropriate manner and then withdraw as soon as possible.
