Can Less Water Meet Growing Needs?

Posted April 08, 2016 12:00 AM by Engineering360 eNewsletter

For the agricultural industry, the challenge isn't just feeding a global population that's expected to grow to almost 10 billion by 2050. It's producing the necessary crops using less of key resources such as water, fertilizer, and arable land. Thus the emergence of a field called precision agriculture, which seeks to employ technology to help farmers grow food more efficiently. Engineering360 examines a few technologies aimed at boosting farming efficiency, including low-cost sensors for individual seeds that could someday reduce the amount of water needed to irrigate crops.

There are limits to growth. It is unlikely that the human population will reach that figure, as some natural catastrophe/hunger/thirst will be a limiting factor. The amount of freshwater per head of population is declining rapidly. At some point, supply will fall below demand and impose that limit.

Don't be crazy sir. Of course the population will reach that value, it has to, here is no choice in the matter. Think about it. Marketing and sales folks and underwriters have already calculated the new business profits and industry growth.

The utilities have calculated for more poles and wires and power stations, solar farms, wind farms, gas lines, land appropriations etc., to supply the increased population and their electric cars and their recycled carbon friendly homes containing 1.956 children, one robotic dog, a cell phone transplanted into their head, and a red jelly bean.

Governments have planned newer taxes to obtain from the growing populations, taxes that can be hidden in new off shore bank accounts, or used to build luxury homes, and you want to ruin all their plans of richness with an undisclosed 'limiting factor'. What the hell are you think??????

Yap, when resources are stressed, there is a limiting factor. Lack of food will result to massive die out of consumers from lower tropic level to high. Kill the grasses and the trees, you will end up killing millions above.

Energy level is a reverse social pyramid. You eliminate the below, the upper level will suffer. However the social pyramid is, kill the below - oh, it doesn't matter up, to some extent its much better to the elite.

We don't have a water shortage, we have a water dislocation problem....

Take a look at Nestle Water to see how big business is sucking free water out of the ground by the millions of gallons for almost NOTHING and selling it for millions of dollars pure profit.

We need politicians who are not owned by lobbyists and big business.

99% of bottled water is a rip-off anyway. If politicians could be kept honest, our tap water would be perfectly healthy.

Fracking wouldn't be causing earthquakes and Keystone pipelines and gas flaring would be controlled, or not allowed at all.

Whilst in BC, Coke Cola Co helped themselves to water from a spring for many years and paid nothing for the water, taking away a resource from the community who paid for water. Coke had wonderful profits at the expense of the community.

So the smart thing to do, stopped buying the big brands products, there would be a water saving, less plastic bottles and tin cans polluting the world.

It is not just lobbyists and MP's, it is the Jo Public who assist the big companies by stupidly buying the products.

If water stands for one day it is deemed stagnant, so why do people buy stagnant water? (Of course, the time limit on standing water to become stagnant is a debatable subject. UK deems approx 5hrs and also the container type is hotly debated.)

So reality is, screw the farmers so that big business can monopolise a God given right to water. Looks pretty normal from where I see it.

I think this topic has gotten under my nugget this day. I recall years ago when living in S Africa, during a really long drought that drained water levels to extremes. The Vaal dam, 320sq km of water, with 800km of shore line and is the catchment area for most water supplied in S Africa. I actually walked across the dam and many boats that had sunk were found in the dry dam bed.

It was found that during the drought, the govt had been selling water to France to Perrier for bottled water to sell back in the drought stricken country. It was such a hardship that people went daily to church to pray for rain while the big companies profited from lack of water for the people. Hippos were found in Johannesburg, that had wandered from the Kruger game park, looking for water and ended up in peoples swimming pools, in suburban areas, baboons arrived in the city for food and water.

I also recall the authorities world wide declaring water will be the biggest money spinner in a few years. They were quite right as I believe it was manipulated to be so by companies and the gullible public bought into it. I have seen the ravages of drought in Ethiopia and the in house fighting in damming up the Nile for hydro power with Ethiopia, S Sudan, Uganda. Egypt, and the drained dams that should be shared by all. And the laugh of it all is that bottled water, (ambo), sells and the big guys profit all the time. In Ziway, there is a dam and the town depends on this water to the point they grow roses and other plants for export to Europe. The grower employs over 18000 people in the green houses. The winery, (French investment privately, owned) employs 10000 people on the estate so this body of water is vital to the people there for income, so why on earth are the Europeans allowing big concerns to usurp a vital commodity for all. It is free from above, it is free to store and simply too many people, animals depend on water, so why do we take this crap from business. Have we all become spineless and brain dead to sort out business or are we just too damned lazy to stick together and ignore the BS business pushes on us.

Rather put the money for bottled water into building better dams and storage bunds rather than plastic bottles. (By the way if you work out the costs of the water versus the plastic bottle, the bottle and cap are the bigger expense of the contents. Now that in my eye is stupidity).

Sad days when business controls the masses in the name of profits. And steals a world wide common resource. Now they want to regulate farmers who produce our life blood with another hair brained scheme and the pubic should buy into this?

(Rant over and thank God I don't drink water or buy bottled water unless it tastes and looks like beer, coffee, tea).

Nothing is free, that's the way the economy works, you sell everything to everybody, this develops a large pool of wealth that circulates throughout the population ever increasing ever expanding raising even the most humble out of poverty to the point they can afford to buy high quality goods and services that provide some comfort in life....Giving things away for free in a developing subsistence level economy does nothing but sustain the present circumstances of dependency...

That's a rather callous, but not unique view. You should be a politician capitalist mercenary Republican lawyer.

You'd sing a different song if I had a plastic bag over your head and your hands were tied behind you.

The point here is that the "value added" to water, and even air, is a total fraud.

How much of that "genuine" sand have you sold?

And that "large pool of wealth that circulates throughout the population" doesn't. It always ends up in the off-shore bank account of the richest 1% of our population.

You remind me of the guy who goes to his lawyer. Guy, "I know it'll cost me but, can I ask you two questions"

Lawyer, "Sure, what's the second one"?

"The point here is that the "value added" to water, and even air, is a total fraud."

Not true at all, what has been added is liability...If the water makes you sick you can sue and get rich....

"Total currency in circulation[edit]

In 1990, total currency in circulation in the world passed 1 trillion USD. After 12 years, in 2002 this figure was 2 trillion USD, and in 2008 it had increased to 4 trillion USD, broken down by country as follows:[1]

  • Eurozone - 1035.2 billion USD, 24.30% of world total
  • USA - 850.7 billion USD, 19.97%
  • Japan - 762.4 billion USD, 17.90%
  • China - 492.3 billion USD, 11.56%
  • India - 140.3 billion USD, 3.29%
  • Russia - 110.8 billion USD, 2.60%
  • UK - 87.5 billion USD, 2.05%
  • Canada - 43.8 billion USD, 1.03%
  • Switzerland - 40.3 billion USD, 0.95%
  • Poland - 37.7 billion USD, 0.89%
  • Brazil - 37.3 billion USD, 0.88%
  • Mexico - 34.3 billion USD, 0.81%
  • Australia - 32.4 billion USD, 0.76%
  • Other countries - 554.9 billion USD, 13.03%

What a crock! Can you say Flint Mi?

Who will you sue if you get COPD because you live in China?

Weak, weak, weak is your currency argument! Need currency? Print it!

Like software advances in computers, inflation eats up all that "extra" currency just like software gets eaten up by more games and complexity in computers.

Does the sand look pink through your rose colored glasses?

Ah but that's the point, the water in Flint and most cities is not filtered, just chemically treated, and not sold by a private company in bottles, but a government entity through a pipeline....just the thought makes me gag....

Creating currency, or quantitative easing as it's called, is created by the central bank purchasing government securities or other securities from the market, in other words retiring some of it's own debt...so the money exists already, just not in cash....a very small amount, percentage wise, of the wealth in the world, is in cash....Inflation is rather subdued lately....averaging 3% inflation for the last 100 years or so....So yes holding cash is not a good way to go ...

"The Rule of 72 & the Impact of Inflation on the Value of a Dollar

The rule of 72 says that if inflation is N%/year, prices will double in approximately 72/N years. For example, at 3% inflation, prices will double in (72/3=) 24 years; at 12% inflation, prices will double in (72/12=) 6 years. This means that at 3% inflation, the purchasing power of a dollar will be cut in half every 24 years; since what you could buy for $100 will cost $200 24 years later, the value of the original $100 has effectively been reduced by 50% -- to $50."

Sorry we're sold out of 'Genuine Beach Sand' at the moment, but you can pre-order as much as you want...

A good comparative analogy is, what would be the effect if you are only given enough water to flush a poop or to wash your clothes or to wash the dishes. Damn, are you gonna be accommodating on a hotel with that theme of concept?

Might as well in food and water intake.
