They will have to use more water from the development of agricu]ture, divert th
e water there. So, for example, in Japan we can see that the rate of irrigation
systems building is dccreasing, that means that more irrigation systems have t
o be out of use, because the,y are replaced by urbanization and so on. Of cours
e, in other cities In Asla this phenome-non will take place. Because that water
, we have only one jar, And if we more for some-thlng else, then we have to div
ert from this thlng to go there. So we have to balance on this. But because we
have to see to It that our food production is not jeopardized, so we have first
to correct the use of water, to improve the management of the water uscd. I th
lnk that is a number one step. We cannot stop the urbanization, we cannot stop
indus-triallzatlon. So what we can do Is to ask farmers to use water, instead o
f using It very lav-ishly, now they have to use it more sparingly. And there ar
e different ways, there are four ways that our legislatlon can prescribe.
Now for the question from the distinguished delegate from New Zealand, the educ
ation on water use. Yes, now several groups, NGOs, are trying to advocate the e
ducatlon of the childrcn, of the women, and of the men, especially those in the
rural areas, on the water resource. And I know of, Iike In the U.S., this move
ment of water education is very strong. And it is moving to several areas in As
ia also now also, and we try to make our citlzens be aware of this limited reso
urce.
There was the question from the distlnguished delegate from the Philippines, da
ms or no dams. Your question is very good. Actually, Iike I present there, each
water work has their pro and cons. For example in Laos now, Laos is golng ahea
d to bulld the Nam Ngum Dam, for example. And the International River Network a
nd other NGO groups are trying to stop this finance of this dam, saying that It
will destroy the environment and have lots of very adverse impact. But the Lao
s government said, Iook, we arc a land-locked country, we are very poor, we nee
d some dollars and the need to sell the electricity is our main source of Incom
e, so let's go ahead and build the dam. So this is why they build the dam. They
can generate electricity to sell to Thailand and so on. But the envi-ronmcntal
impact, they think not in their land. But actually it is, there will be a lot
of ar-eas will be flooded, Inundated because of the dam. Now for each of each o
f these dam projects. I think that there some will be very beneflcial if it is
not affecting a large popula-tion on thc upstream or the reservoir areas, and i
f It is not affecting the downstream, does not invite salinization or acidifica
tion of the soil downstream.
The question from my chairman regards the balance of nutrition in the soil. Dol
omite is a sort of magneslum. Actually in some kind of soil it is quite acidic,
then the ratio between calcium and magnesium is out of balance also. So they c
an lime It, put more lime for cal-cium, to make it less acidic. But because of
the magnesium status in the soil is too low, then no matter how much nitrogen,
phosphorus, potassium and lime we put in, then the crop will not increase unles
s they balance it with the magnesium. Dolomite is one source of magnesium in m
any acidic soils. Thank you.
