Sustainable food production is possible, but not with 'business as usual' : Comments

By Shenggen Fan and Klaus Töpfer, published 21/11/2011

Water is the biggest constraint on agricultural production, but generally countries only look domestic and industrial use.

nocsg, you have this hate for .CSG.

Where is you evidence that CSG destroys aquifers?

Also, this industry does not use much water, apart from dust suppression and compaction.

What they actually do is desalinate the water, then release it through natural channels.

Best you get your facts from experts, rather than from those on the news trying to distort the truth.

CSG means jobs, jobs and more jobs, and they are a highly monitored industry.

Hasbeen relies on very obvious and long discredited lies which misrepresent scientific findings and distort empirical fact. Why? Clearly an effort to mislead. For example, Hasbeen tells us that:

sea level is now dropping,
[There has been] No heating in the last 12 years & now none for 3 decades,
how is it going to be up 2 degrees by 2040, less than 3 decades away?

Sea level is continuing to rise at a rate of 3.2mm/year according to satellite and instrument measurements. It does not rise continuously or at the same rate every year so it is easy to cherry-pick data and point to short periods when sea level did not rise. But measuring sea level rise over a 30 year period shows clearly that it is rising and has been doing so for over a century. See graph here.

No heating in the last 12 years? That is over the period 1999 – 2011? Indeed there has been. What Hasbeen meant to claim was … No heating over last 13 years – that is over the period 1998 – 2011 but Hasbeen can not even cherry-pick the period properly. It is important to include 1998, the hottest year in the 20th century, though not the hottest on record. Doing so tries to distort the truth of the matter which is that mean global temperature has been rising and doing so at an accelerating rate over the last 50 years.

Hasbeen assures us that over the last 30 years, that is since 1980, there has been no global warming, but the fact is that during this period, global temperatures have not only risen but done so at an accelerating rate as shown by the graph here: http://www.ncdc.noaa.gov/bams-state-of-the-climate/2009-time-series/land This plots temperature increases compiled by 4 different reputable agencies.

Mean global temperature has already risen at about 0.034C/annum and unless it slows down, it will have risen by 2C above pre-industrial temperature by 2040. There is no indication that temperature rise is flowing or falling. Indeed the rate of temperature rise since 1980 should be ringing alarm bells – and it is for everyone who is concerned for our future and informed.

It is all very well to assert that sea level rise and global warming have stopped it is wrong to expect anyone to take such claims seriously when (a) they are contradicted by empirical measurements and (b) no supporting evidence is provided.

Agony I told you that the leaked IPCC report predicts no warming for 30 years, not none for the last 30. Do try to read through the red mist that descends when you see facts.

No rehctub I don't hate CSG. But prove to me that it can be done with out impacting upon the aquifers in the driest continent on earth. My evidence comes from the National Water Commission, various Environmental Impact Statements from Queensland and written by the industry itself, contless other places. I am not an extremist but this industry has been developing without any independent scientific analysis. And it is not regulated - does not even have its own act! One look at a gas field in Queensland or America shows quite clearly that agriculture and CSG cannot and never will be able to co-exist with agriculture. And there is nothing in NSW legislation to protect the farmers. So while this industry is under so much suspicion - leave the gas in the ground.

Further more there is plenty of evidence that it damages and destroys aquifers - Ross Dunn of APPEA even admitted to it. As for water, it extracts huge amounts of artesian water which results in a drawdown on potable aquifers. It also requires large amounts of potable water for drilling as well as fraccing. Sadly I think that your information is coming from the gas companies. It is a highly water intensive industry. Water once extracted from the coal seam aquifer has to be treated extensively - it contains large amounts of sodium bicarbonate and heavy metals. And still no solution for the disposal of the leftover salty residue which is considerable. Millions of tons of salt to be disposed of. Read up on the latest Senate Inquiry.
