No i am not suprised. I didnt say i agree with wiki anywhere.
Nit picking at numbers is not the issue here for me, food quality and security is...but anyway....your source states 33 1/3 percent, is this derived
from the 2001 census? ...In my Willa Wonka story i mention 40 %, other sources i have read have mentioned almost 50%...it is somewhere in this
ballpark of 40% and these are the numbers being mentioned.
I know there was a National Ag Census in 2006 or thereabouts but i havent looked into the figures on that one...there werent many restrictions before
2006 for irrigators on the major food producing sections of the Murray and some of its tributaries... infact NONE as far as i recall, in ALL of South
Australia, the Victorian Lower Murray and Victorian Goulbourne Murray water authorities...which had full allocation along the Murray in 2005.
And some irrigators had become even more efficient (therefore productive) than ever in recent times (before water restrictions) thanks to advances in
(and lower costs of) technology such as irrigation monitoring software, pump controllers/telemetry, fertigation and better harvesters.
And i havent mentioned the massive plantings by M.I.S. schemes, which were juvenile (non productive) or non existant in 2001...since then the likes of
Timbercorp, in partnership with Select Harvest and Boundary Bend have converted ex dry cropping farmland into large scale irrigated tree crops...16
000 acres or 2.5 million olives and approx 40 000 acres and even more millions of Almonds to name but a couple off the top of my head, and thats not
including the citrus, stonefruit and vines that Timbercorp has planted sine 2001.
One has to travel between Mildura and Swan Hill to see for themselves the magnitude of these plantations which have only recently matured into
production.
Remember these tree crops make 8 to 10 times more money per litre of water used than a cow.
So the real figures in recent times are debatable, because the M.I.S. plantations were maturing and becoming extremely productive and efficient in
2004-5-6
Even 33% is still high, and consider other factors whch have affected food production in recent times throughout the country...
1. Cyclones in Northern Qld, crops damaged.
2. Recent floods in the top end... 150, 000 cattle dead, and some crops ruined.
4. Fires in Yarra Valley near Melbourne wiped out numerous vineyards and tree crop orchards.
5. Northern Adelaide plains, (the glasshouse capital of Australia where there is 30 000 Megalitres of water allocated to vegetable production)
producers there are also leaving in herds due to unrealistic prices from Major supermarket buyers, and encroachment/shifting of urban boundary into
Penfield and Virginia irrigation districts, as well as a 500 million dollar Northern Expressway freeway cutting a swathe straight through this area,
therfore the compulory acquisition by the State Givernmen of many acres of land that were previously producing vegetables under irrigation.
6. Extreme lack of rainfall in most of South Australia, North and West victoria and SW NSW has greatly reduced grain harvests, with many growers in
debt and considering getting out.
So no matter what the exact numbers are, the fact is that our food prduction capacity in this country has been seriously dented in recent times, and
this should be of concern to all who do not wish to indulge in imported GM modified or poisoned food...
our growers simply cannot get away with the pesticide residue levels that is found in some imported foods...and the authorities here are virtually
powerless in a legal sense(or dont want to) punish for example Chinese foods when found to contain excessive additives, pesticides or toxins...
