Human settlements were built then. Human settlements are built now. But what has changed immensely is the nature of intervention - they were very very local then and they are seemingly becoming more and more dependent on external produce now. They were planned by realised beings then and they are now being planned by beings with no or very less realisation of the functioning of a human society within the natural realm whose primary focus should be an individual personal development as per his/her distinct capabilities. The number of relationships were less then and it can be said that it was a bit easier then to plan efficiently but the planners of the society should undergo at least that much of pain to understand the inter-dependent nature of a human urban ecosystem if they really are concerned about efficient and productive human urban development.
The isolated nature of the various kinds of specialisation being taught to the budding planners leaves a very small ray of hope behind for real efficient human development - its the wholistic vision and implementation which is upmost needed in present times when there arises a new set of urban issue every now and then and we seemingly have forgotten that very old wise proverb - ‘precaution is better than cure’ and have been falling on the lines of ‘let the issue arise, we will sort it out then’. The latter has proved catastrophic across the Globe in various human urban settlements and we should be sincerely serious about planning the lives of human beings and the future of our planet simultaneously.
We should stop hiding our spineless plans under some fancy words. As time progresses level of human advancements changes but that doesn’t changes the essence and purpose of being a human being for whom cities are planned and developed. The basic concepts are needed to be put straight back into their deserving places. To understand something as profound as human development only basics can serve as the foundation from where everything else arises. The perspective with which it is currently being taught at various universities and institutions is too limited to produce quality planners and planning isn't at all that one thing which the community can/shall compromise with - from the nature of planning exercise arises everything else - the nature and character of a human urban settlement and those of its citizens.
The nature with which cities are being planned especially in the technologically developing nations in general is very disappointing which often superficially discusses big words like 'sustainable development' or 'safe cities' or even 'smart cities' without even understanding a real bit of what these words literally stands for. The fraternity related with urban human development shall understand the holy nature of the profession they are attached with as not only the lives of human beings are at stake but the entire natural system is also one of those influential things which would be heavily influenced by the ever-increasing perspective less human interventions in a phase when our race - the race of human beings is experiencing the most widespread urban revolution of all times of our collective existential history.
