Quietly does it...

Just quietly slipping into your feed again after a short break. No fanfare. No big announcements. No grand plans. Just this, after an extended hiatus, followed by a planned "grand" return that fizzled out before beginning.  It's just like another corporation quietly dropping their net zero ambitions, expecting nobody to notice.  Why now? If you haven't been living under a rock the last few months (and I'd be slightly envious if you have) you will be well aware of the climate related news.  We have seen tumbling temperature records already this summer. Highest May and June temperatures in the UK, record temperatures across much of Europe and parts of North America.  Events for the US semiquincentennial celebrations were cancelled in DC due to extreme heat and New York City had established cooling centres for vulnerable people. The UK has had three heatwaves already by mid-July. Wildfires are widespread with multiple fatalities in Spain and hundreds of thousands eva...

Aphid Resistant GM Wheat

The Rothamsted Institute has frequently been in the news in recent weeks over their trials of a new genetically modified strain of wheat. This particular genetic modification splices genes from other plants, such as mint, hops or apples, which naturally produce an odour which simulates that released by aphids when distressed or under attack. This phenomenon has evolved in some plants as a natural defence as aphids that would otherwise attack the plant detect the odour and avoid the host plants.

Can Organic Agriculture Feed the World?

I'd like to think that it can, but I have often wondered wether organic agriculture could feed everyone or whether we need more intensive agriculture. There are many environmental benefits to organic methods including reduced use of herbicides and pesticides such as neonicotinoids which are implicated in the decline of bee numbers. Another benefit is the greater diversity of vegetable varieties also associated with organic farming. This is for two reasons: to use varieties with greater natural resistance to pests and to use more flavoursome varieties to differentiate from non-organic produce.  A recent study of studies of yield from organic methods compared with so-called conventional methods has recently been published in Nature and reported here by the BBC. From the BBC report: The headline conclusion is pretty unequivocal; across the board, organic farming produces lower yields than conventional methods, by about 25%. For fruit, the difference is marginal, just a few percen...
