yes, but I admit it

Wow.

.. and the UK is rapidly becoming a water-deficient country too..

not for agriculture. May have to ration domestic use in the SE

Crops aren't being irrigated there yet?

some vegetables and potatoes

not such things as grazing land

I remember the summer of '95 in Essex. Grass all burned up.

yes, and did you see any irrigation of grassland because I travelled pretty
well right round the country that year and never

No.

Any idea why England is experiencing this extended drought?

what extended drought, there is some shortage in some regions but talk about
extended drought in the west and you'd be laughed at

'This is what has happened in south-east England. Two dry years
have reduced the amount of water available to both people and the
environment. You can see from the diagrams on the right that since
October 2004, south-east England has only had a few months of
average or above average.

Why is winter rainfall important?

Winter rainfall is vital for water resources because it fills reservoirs
and groundwater and increases river flows. As temperatures rise
in the spring and plants and trees start to grow, less rain reaches
rivers and groundwater.

The past two winters have been dry in most of England and Wales
which is unusual. South-east England relies on groundwater for
most of its water supply, so two dry winters meant groundwater
levels had not recovered at the end of the 2005-06 winter and this
led to the current water restrictions.

A wet May and August plus reduced demand helped the situation.
However, another dry winter could cause problems next summer
for those in the region.

'Outlook

A wet autumn and a wet start to the winter have meant most
reservoirs have recovered and groundwater levels are improving.
In south-east England we are in a better position than this time
last year and the signs are encouraging, but the drought is not
over. If the weather changes and the rest of the winter is dry,
there could be further water resources problems next spring and
summer.

The question is, is it part of a trend like, conversely, flooding.

"Our study carried somewhat surprising results, showing that
although the major impact of deforestation on precipitation is
found in and near the deforested regions, it also has a strong
influence on rainfall in the mid and even high latitudes," said
Roni Avissar, lead author of the study, published in the April
2005 issue of the Journal of Hydrometeorology.

Stick with UK seasonal vegetables

I'd like to see evidence of vegetables causing water depletion.

Simple.
What is the water content of most vegetables?

If it's that simple you should be able to provide evidence
that vegetable production is causing water shortages.

you just did, vegetables and potatoes are the only crops in the UK
needing
irrigation

Those crops have always been grown there, so they're not to blame.

duh, they need irrigation because more of them are being grown in larger
areas, therefore they are part of the problem

False. The problem has been a lack of rain. A drought, in other words.

And for imported crops it is simple, work out the water content of
vegetables, multiply it by tons exported, that is the amount of water
that
country exports.
If that country is already water deficient, you are merely making things
worse by exporting vegetables

Why are water shortages occuring? Address and eliminate the cause.

'Livestock now use 30 percent of the earth's entire land surface,
mostly permanent pasture

yep, and large areas in the UK, because that is where we produce our
livestock here, is permanent pasture because it is unsuitable for arable
cultivation

Arable land is, but a significant percentage is being used for feedcrops.

And what's wrong with the UK soil, that it's 'unsuitable' as you claim?
Remember that Britain used to be almost entirely woodland. Will you
also say that "permanent pasture" is unable to support fruit orchards?

how can I know where you food comes from,

I don't know, but your statement above indicated that you do.

You lied, again.

How can I know where your food comes from

You should have thought of that before you blurted out "most of
your
food ingredients are actually imported from water deficient
countries
...".

good, so where do your food ingredients come from then?

For argument's sake, and because it involves everyone, let's
say that my "food ingredients" come from all over the world.
Now tell us what should be avoided (support with evidence).

simple
Don't eat imported food.

That rules out livestock products then, as you use imported feed.

yes, but I admit it

Wow.

Simple.
What is the water content of most vegetables?

If it's that simple you should be able to provide evidence
that vegetable production is causing water shortages. In
fact it is the extensive deforestation to create pasture and
feedcrops that has caused aridization; now compounded
by the need to irrigate to keep up your omnivorous habit.

'(i) Micro-climate: Deforestation of TRF leads to drastic
changes in microclimate (Lal and Cummings, 1979), as
outlined in Fig. 6. In general, deforestation eliminates the
buffering effect of vegetation cover and accentuates the
extremes. Fluctuations in micro-climatic parameters are
greatly enhanced (e.g., relative humidity, maximum and
minimum temperatures for soil and air). Deforestation
decreases rainfall effectiveness and increases aridization
of the climate. Forest removal increases the magnitude
and intensity of net radiation reaching the soil surface.
Ghuman and Lal (1987) observed that in south central
Nigeria, on average, 10.5 and ll.5 MJ/m2/day of insolation
were received on a cleared site compared to 0.4 and 0.3
MJ/m2/day in the forest during the dry seasons of 1984
and 1985, respectively. There was no appreciable
difference in solar radiation received under forest during
the rainy (May) and dry (December) seasons (Table 8).
Vegetation removal also increases wind velocity (Table 8).

Deforestation decreases the maximum relative humidity,
especially during mid-day. There is also a corresponding
increase in air temperature and evaporation rate. Perhaps
the most drastic effect of deforestation is on soil
temperature. The maximum soil temperature at I to 5 cm
depth can be 5° to 20°C higher on cleared land on a sunny
day compared with land under TRF cover. Because of
high soil evaporation, the soil moisture content of the
surface layer is also lower in cleared than in forested soil
(Fig. 7).

After all you are a vegetarian

So what. We all eat (-need- to eat, for survival and good health)
vegetables, fruits, nuts, legumes and so on. Try living without.

then why do you buy imported vegetables?

People buy imported vegetables because a wide variety
of fresh produce is important to maintain good health.

Why won't you comment on the inefficient overuse of water
for the livestock industry, jim? You are too embarassed to?

no, we use all that water that falls on grass or would otherwise go to
waste

You're forgetting about all that imported feed.

don't need to, you rant on about it all the time

You do need to, as you are trying to shift the blame onto others.

but it has taken over a week to admit that you are every bit as guilty

I have not. There's no way I could be. It is inefficient
unsustainable
consumption for and by the livestock industry that is causing global
water shortages, - requiring 15 to 22 times the water for the same
amount, and at about 40 percent of global agricultural output, that's
nearly twice as much as would be used for plant foods alone - and
~you~ try to blame foods being produced for human beings directly.

Shame on you, webster. Maybe one day you'll find a backbone.

I'm not the one who took over a week to admit what she eats

Stop lying already, webster. I told you way back what I eat.

and still cannot
conceed that by importing vegetables she is importing water

You still can't provide evidence of vegetables causing drought.

Also if water is such a big deal, I'd point out that the amount used in
agriculture in the UK is less than is used by the domestic population

What percentage? A link with that would be helpful.

How many liters of water do bovines consume per day?





Why don't you just FOAD

Why don't you stop behaving like a prat, and stop all this crossposting to
