The Top Ten Solutions for Salinity
As anyone who has dealt with the problem of salinity is well
aware the issue of salinity is one that has no simple quick
fix solution. Indeed most solutions really involve a complex
series of actions that put together result in a solution. The
problem is that we do not know enough about the problem we are
trying to alleviate or even fix in some instances and to most
peoples minds we do not have enough solutions in our toolbox
at the present time to be able to offer help to those affected.
Incidentally I have constructed this from an economic perspective.
I am passionate about the environment however any person who
has any connection to the land knows that a farmer going broke
seldom does much in the way of conservation and economically
sustainable environmentalism has a far more realistic ring to
my ears. (There is nothing worse that a vermin and weed infested
National Park that is that way because theres not enough funding
to maintain it properly)
Here goes in any case
Number 1 - Increase Government Spending
I dont think I would get any agruement for anyone working
in the field of salinity with this one. The arguments come on
how!!! I am of the belief that we need to tackle 50:50 the research
of understanding the problem and solving it. The problem is too
far advanced to just concentrate on understanding it we need
solutions but that said there have been some misplaced efforts
in the past so lets increase our knowledge on what is going on.
Number 2 - Education
Understanding the problem helps us to solve it. Education
would mean that peoples remediation efforts would be well targetted
and would deliver results.
Number 3 - Drainage
Where this works (highly dependant on soil type) it is a ripper
just ask the farmers in the Upper SE of SA. Its not for everywhere
but is a commercial option (which is important) that offers real
solutions to some people affected by salinty.
Number 4 - Pyramid Salt
Not sure how economic this would be if every one copied these
guys but hell its a great story. Pumping the scourge of the earth
from the ground making a product from it and growing horticultural
crops in the reclaimed area. I love it!!
Number 5 - Tree Plantations
Not in the problem areas but up the catchment stopping the
recharge. Hopefully the prospectuses live up to expectation and
the tree growers are around for some time to come.
Number 6 - Grazing Plants
Puccinellia, Nypa Forage, Saltbushes, Paspalum they have their
advocates and their critics what is the important thing is that
useless land is returned to production.
Number 7 - Fish Farming
I dont think this is economic yet but should have a future
with declining wild fish stocks what better way to use salt water
than grow yourself a nice feed of snapper!
Number 8 - Desalinisation
Expensive technology at present but one way of dealing with
the menace. Keeps us in our comfort zone of fresh water. It also
cannot cope with the volumes of water in question.
Number 9 - Evaporation ponds
Not a favourite of mine as I dont feel that most of these
schemes give much thought to the disposal of the resultant salt.
Number 10
You tell me!!! What Have I left off the list let me know and
I'll add it!!!
