Wheat Rust Genes Understood After 30 Years

The genetic makeup of wheat rust has been a mystery for over 30 years. Puzzle of wheat rust genetics solved after 30 years by scientists. Researchers from CSIRO, the University of Sydney, Limagrain UK, the United Kingdom's John Innes Centre and the National Institute of Agricultural Botany (NIAB) have identified the first three resistance genes against stripe rust disease which devastates world wheat crops. UK and Australian scientists solve 30-year wheat rust genetics conundrum.

Climate Change is Inevitable

Australia is one the world's major producers of wheat. If climate change reduces national output there will be widespread consequences. The economy will suffer with the need to import wheat. Internationally, a wheat shortage will put prices up and many poor people will have to go without.

On the positive side some regions of Australia will get more rain. People will still be able to "fatten up" on sugar and rice, despite research showing that sugar contains no nourishment whatsoever for the human body. Two centuries ago a group of British sailors was shipwrecked on the west coast of Africa. The ship was beached. Even though the ship had a full load of West Indian sugar they all died of malnutrition.

Getting back to the main point. There will be competition for arable land pushing land prices up. There is also a link between the land and sea. Climate change will reduce the fish catch. Living in the bush will become impossible with farming failing to prop up local economies.

Potential for farmers to move up into higher areas is limited because Australia is a flat continent. Of course, we could all choose to move south. This would create the need for massive new investment in infrastructure.

These problems will affect the generation of children living today. By 2050, the food bowls in South Australia for sheep and beef will be no more. Man had little impact on the environment in the past, so we do not have the "genes" to change our ways. Pollution will inevitably continue until all the damaging changes above come to fruition. People working today will for the most part be dead. "It isn't our worry is it mate?"
