Weeds evolving faster than herbicides.

On Bush Telegraph on Radio National this morning, an interview with Weed March, a Western Australian group formed when they realised weeds were now evolving beyond the chemicals they use. Chemical companies along with farmers and others are talking about what they can come up with. Wide range of approaches were the best thing I heard, but with the emphasis on more chemicals. For a start my thinking went to what do you expect when mono culture in agriculture dominates. With the push to GM and round-up ready crops, surely its common sense that nature will evolve. In my organic garden and after this present deluge of water, I expect to see a number of new plants germinate. I use all these plants as mulch and if I keep them from seeding next year will be different again. That is the reality of nature. With GM seed, its round-up resistance will decline as so-called weeds will adapt for their survival. In my garden 10 different mis-placed plants, amongst the vegetables ,will germinate. I remove them and leave some as ground cover to dig in before flowering. The non-organic farmers will be sold another chemical. Emphasis in my view should be on focusing on what and where we grow food and we do it as close to mimicking nature as we can. Climate variability has to be about adaptation and nature will lead the way. Our rain here these last 3 months could be about lack of rain next year. What I plant next year will be determined by the reality of the season.

Further to Councillor Dey’s support for coastal retreat and his mention of Venice, the Italian government is prepared to spend $5 billion for ocean gates that shut out high tides to preserve Venice for the short term. The gates are an example of human ability with amazing technologies, and… a great foolishness. In the long term with global warming, Venice is lost.

With a prefrontal cortex three times larger than any other animal, humans are able to perceive that there is a future; that there is a long term. However, if the long term is only noticed to create technologies and not to notice that there is a prima facie case that all technologies create greater long term degradation than there are short term benefits, then there is partial regression to the prehuman.

Five billion dollars could have put a lot of compost heaps on the Earth’s surface or supplied many biochar stoves. Compost heaps and biochar are not just bulwarks against the causes of climate change in that they soil sequester carbon, they are foundations of a sustainable, gardening agriculture, and, because nutrients are in a greater bound form, they are less leachable to watercourses. In short, they aid in repair of air, water and soil, the three bases of life.

The short term shoring up against ocean rise can be seen as a waste of money that would be better spent provisioning the long term and future generations with bulwarks against the causes of climate change rather than a too late attempt to fix effects. Not too long ago, humans automatically knew it was important to provision future generations, but that understanding is rapidly being forgotten. Is it any wonder that Byron is sometimes trashed by youth
