I know that
Stuart always likes a good debate (see comments on my previous posting) but to suggest that farmers should relocate to areas where there is plenty of water is no solution at all. The whole situation is far too complex to deal with in a blog, and I certainly don't have the answers, but a few points worth considering are:
1. The areas most affected by this drought - large areas of South Australia, New South Wales, Victoria, Tasmania and Queensland - 'normally' have sufficient rain for most of the agriculture undertaken in these area, ie. crops, beef, dairy, wool, etc.
2. The majority of this land is highly productive land - it is definitely NOT the Sahara.
3. Areas where there is ample water at present are mainly in tropical regions, unsuitable for the staple agricultural crops grown in the south.
4. Farming is not 'just a job' where you can move from place to place with little disruption. Farming is a 'way of life' which incorporates the entire family, and in many cases, has done for several generations.
5. A country like Australia needs its Primary Industry - we cannot compete with many other countries in the fields of manufacturing and technology, and service industries are not income generators in themselves.
Having said that, I personally feel that many farming methods over the past 200 years have unwittingly created many of today's problems, such as:
1. Wholesale clearing of timber for farming has resulted in salinity, erosion of topsoil from wind and water, and created larger, drier areas with decreased rainfall.
2. European methods of farming are in many cases unsuitable for the drier, hotter climate of Australia. Multiple cultivation of the soil exacerbates these problems.
3. Some of our crop choices are dubious, eg. rice and cotton. Although I have read that more water is required to produce a kilo of beef than a kilo of rice (usually quoted by non-meat eaters). Perhaps that is true.
4. We used to be able to produce most of our Primary Industries without relying so heavily upon irrigation. What's changed?
These are just a few of my random thoughts on the subject. No doubt I'll go away and think "I should or shouldn't have said that, etc." But I would be interested to read what others think on the subject, even though I know that I won't always agree with what I read.
