While the Himalayas are almost uninhabited the plains in the valley of northern India are one of the most densely populated places on earth. The Himalayas can be seen as the cathment area (or rainwater harvesting system) for the plains of Northern India. They  'irigate the plains through their rivers and provide an almost continuous resource of meltwater with their glaciers.
These plains are the basis of the agrarian society that until now lives for a large percentage in villages. The villages are in general rather small and dot the entire valley at distances of only a few kilometres, in between we find the agriculture land that produces a big percentage of the food of India.

With rapid development in India society is changing and development is happening basically in the cities. The cities absorb more and more villages that surround them.
And if you look at many cities now you may come to the conclusion that they exist of many villages that grew closer to each other. Delhi for example consists of 250 or more enclaves that mostly were villages and have become closed communities. In between the communities of Delhi lies a no mans land: a forest area, slum zone or waste land, large scale infrastructure and polluted small and larger rivers.
The cities of Northern India are with the fast development of India now growing at a higher speed and incorporate more and more rural area. But we don't want the Delhi scenario to happen to be the future development as it makes the city and the rural area into unlivable environments.
In Punjab alone about 200km² is turned from agriculture land to urban land for urban development. This land should be developed in a sustainable way: integrating rural and urban as
