Peat – sink or source
It was reported in the news today that the UK’s carbon emissions rose by 1.25% over the last year, while overall greenhouse gas emissions stayed on Kyoto targets. Many people won’t be too concerned by this rise, seeing that we are still well below the 1995 CO2 emissions and have reduced other greenhouse gases. I…
MUM’s not going to poison you
When I buy mineral water, though I don’t usually read the label, I generally expect it to contain the usual sodium, magnesium, calcium salts. Commercial bottled waters in most countries I have travelled to supply this information as a result of a legal requirement. What did come as a surprise was the approximate mineral composition…
Cataloguing Life
Today sees the launch of the Catalogue of Life, a taxonomic checklist of 1 million of the world’s organisms. The catalogue contains contributions from 47 databases constructed by more than 3000 taxonomists and species specialists from around the world.

Cow + Grass = House
Cows plus grass equals dung; 7-9 million tonnes of it each year in the USA alone! What if cows plus grass made flooring?, or shelving? or a table? Michigan State University researchers, working with the US Department of Agriculture, reckon that the "digester solids" leftovers from anaerobic digestion of cattle manure can be processed into…
Fancy a bottle of Swedish white?
At the moment, the idea of wines from Scandinavia, or other northern climes, may seem fanciful. But by the end of this century, climatologists suggest that Sweden could be producing Riesling or Chianti, Germany will be better known for luscious red wines than the current whites, and California’s famous Napa Valley could be as hot…

Drink coffee, feed the world?
As I sat bleary-eyed in the staff restaurant at CABI drinking a morning cup of coffee today, was I simply having a shot of caffeine to keep me going after an early start. Or, as it was Fairtrade coffee I was drinking, was I making a real contribution to improved livelihoods of small farmers in…
Conservation agriculture: the zero way
Brazilian farmers are at the forefront in the application of Zero Tillage, a cropping method that is greener, boosts productivity, and helps the climate. “Called direct drilling, no-tillage or zero tillage (ZT), the technique is in part praised for fixing carbon in the soil, thereby reducing the amount of carbon dioxide — a greenhouse gas…
Water or biofuels? You choose.
A recent editorial written by Fred Pearce in Sugaronline.com points out the alarming possible repercussions of growing biofuels for the world’s water supply. As the policy makers seriously consider this option as an apparently climate change-friendly method of fueling the world, we have to consider what affect this might have on other, already stretched, natural…
Tortilla crisis: how green fuel may be harming Mexico’s poor
In the face of global warming which is now acknowledged by almost all to be at least partly man-made, and of high oil prices and worries about dependence on imports from politically unstable regions, the idea of renewable energy from plants seems a very attractive one. Biofuels aren’t at risk from political upheaval or terrorism,…
