Nice post Hallen.

India's water problems you would think be solved by the Monsoons!
Isn't that a lot of Rain??


What is your prognosis?

[Zythryn]

My (poor) understanding is that the monsoons dump tons of water, of which most runs off. What is needed is longer/more periods of more gentle rain that can soak into the ground.
Doesn't India also get much of its water from annual glacial melting?

Not all! No one can harvest all the rain water (there are problems associated with storage). But still if most multistory housing blocks have provision for rain water harvesting, it may mitigate the travails of many city dwellers.

That's indeed true! but with the burgeoning population and rapid industrialization, pollution can not be avoided as many industries that consume much water never care to treat the affluents.

Thanks hallenrm
Unfortunately with my 44Kbs 3rd world system it took an age to download and then Easter hit. I will have a good read of it later in the week.

This was on ABC Landline today, I missed the show (Easter %^$) but here is the transcript.
The World Today - Growers hail new turf that can be watered with seawater
For those who really want a lawn in a dry climate this seems too good to be true
Grass that can be watered with:-

GREG MILLER: It can be water with saltwater, it can be water with freshwater, potable water, it can be water with dirty water, like your sewer water, it can be water with your dishwashing up water, it can be water � anything you can throw at it, it'll grow in.

TANYA NOLAN: Sea Isle Turf was developed in the United States almost 20 years ago, by a scientist at the University of Georgia.

Here's a nice link on what one Aussie is doing to turn that salt land into fertile growth.

Fantastic link thanks
Nature is so resilient.
I have posted it on the Permaculture Forums

Deserts too have their ecology that needs preservation especially in untouched areas of Australia.

The Middle East has been so denuded by man anything is an improvement

How come "it"s and "in"s are red in this thread?

This is a innovative way of storing masses of rainwater when building a new basketball court, sports field, container terminal, parking lot, building, foundation, or maybe even a shopping center

The storage of rainwater in the Netherlands is 'hot'. Buffers can prevent flooding and intelligent usage of rainwater can save money. Several Dutch companies have realised that there is money to be made in the development of storage systems. One innovative example is the 'Watershell', an invention by a family business in the southern village of Zundert.

Professor Discovers Better Way To Desalinate Water

Science Daily — Chemical engineer Kamalesh Sirkar, PhD, a distinguished professor at New Jersey Institute of Technology (NJIT) and an expert in membrane separation technology, is leading a team of researchers to develop a breakthrough method to desalinate water. Sirkar, who holds more than 20 patents in the field of membrane separation, said that using his technology, engineers will be able to recover water from brines with the highest salt concentrations. The Bureau of Reclamation in the Department of Interior is funding the project.

Kamalesh K. Sirkar, PhD, is a distinguished professor of chemical engineering and the sponsored chair for membrane separations and the director for the Center for Membrane Technologies at New Jersey Institute of Technology.

"Our process will work especially well with brines holding salt concentrations above 5.5 percent," Sirkar said. Currently, 5.5 percent is the highest percentage of salt in brine that can be treated using reverse osmosis.

"We especially like our new process because we can fuel it with low grade, inexpensive waste heat," Sirkar said. "Cheap heat costs less, but can heat brine efficiently."

All solutions are short term unless there is a radical change in population. There is more capacity on the earth than we realize, but we cannot have people living where supplies are not available. Distribution, not supply is the biggest issue.

You are so right. In primitive times the people would pack up and move to find food, to hunt. Take American Indians or the Eastern Woodland Indians who would go out, hunt and set up temporary tepee homes. Some other groups moved in their entirety because they had the desire and motivation to survive.
The funny thing is it seems most Alien movies have Aliens coming to Earth in search of new resources because they depleted their own. Well, What do you think we are doing? Depleting our own resources and searching outside of Earth for new. So, why do people of any country insist on living in an uninhabitable or resource depleated environment. If you say Money, well Indians and Nomads didn't have money. Do or Die, Non?
