41% of continent surfaces are deserts and it will be worse in the futur; what do you do for it?

Question

I do something to irrigate the deserts , but nobody care about my work, why?
see my job:

the video show a video of an experimental canal . In real ,it can be longer.
The water is not lost all along the canal , it infiltrate in deep underground instead to go back to the sea.
Use your head to think , not to tell stupidities

Thank you for your answers, i appreciate its . Here in France when i ask the sames questions the moderators delete it or only stupids guys answer jokes.

Answer 1

KEEP UP THE GOOD WORK.

Answer 2

I think basically the problem is, that the deserts are very vast and huge. You can't irrigate a whole lot of the desert itself. Take for example Dubai and Bahrain for example, they are truly terraforming the desert, bringing in the sea water to create lagoons, and irrigating the desert from desalinated seawater which is basically an undepletable source of water. Or look at Egypt and the Nile river, just a small part of Egypt is lush and green. The Nile delta and the banks of the Nile. So you need water right next to the desert that needs to be irrigated to create a lush environment. You probably can't take water and irrigate the inner part of Australia for example. But the shores of Australia is lush and green, because of the water.
Deserts are a part of the earth's climate zones, they are just a few degrees off the equator to the north and south. The expansion of these deserts are sped up by humanity's strong pollution that make global warming a serious problem. But the desertation is a part of the climate cycles which come and go in a few thousand year periods, but this is coming faster now, that our population is using uncountable masses of energy for a bit more than 100 years now. Take the mid 1800's and the coal plants for example as the start.
So my conclusion is that, yes you can irrigate smaller parts of the desert for some time. But, no you cannot change the desertation process of the earth, we cannot change the climate cycles unless someone creates a rain cloud creating machine. (joke).

Answer 3

Deserts are actually shrinking. Satellite imaging has shown the Sahara has been receding since the late eighties.

Here: http://news.bbc.co.uk/1/hi/sci/tech/2267652.stm

Global Warming and the melting of the ice caps will release much more stored water into the hydrological cycle, so this trend is likely to continue. During the last ice age, for example, parts of what is now the Brazilian rainforest were desert, due to the amount of water being stored in ice and unavailable to the global hydrological cycle.

I would be interested to see the sources for the percentages you quote, and your classification of 'desert'.

Answer 4

Do nothing - thousands of years ago the sahara desert was a thriving fertile bushland with temperate climate. Also the Antartic continent was not covered in ice and was also a sub tropical jungle. There are vast oil reserves under the ice pack of Antartica. It follows that the planet is self regulating and will from time to time reflect different habitats as this is nature at work.

The sub-saharan region has the highest concentration of mineral phosphates on the planet ( fertiliser ) - i suggest you use this to make the desert bloom with roses and tomatoes as they have done in Morocco by pumping water from the Atlas mountains.

good luck on your project.

Answer 5

Dude, I watched your video. You are not irrigating the desert, you are moving water through a trench about 200 meters, losing about half of it because it is not in a pipe.
Stop it. Seriously.

Answer 6

It is better to reduce the world's population.
Tie all foreign aid to rigorous policies of birth control.
Only pay welfare to single mothers on production of a certificate of sterilisation.
This should eliminate many of the parasites from our society and reduce the strain on the world's resources.

Answer 7

well i say good for you!!! not many people care because they think it is all too late. Keep it up though and prove that we can still slow down and hopefully stop the effects of global warming and stuff

Answer 8

Buy property on the NW or NE US coast. It will become prime restate worth lots of $$.

Answer 9

cause 70% of the world is under water

Answer 10

you care, plants and trees care, they are also living beings,
enjoy them, that is the best reward
