Bordeaux vineyards to dry up by 2050: study

A new report published this week spells bad news for lovers of French wine. The study predicts global warming will nearly wipe out production in the traditional regions of Bordeaux and the Rhône Valley by the year 2050.

The rise of the oceans, and  the destruction of traditional crops can sometimes seem like a distant prospect, but a report by US based researchers released on Monday makes frightening reading for  French wine-enthusiasts and more so for the vineyard owners in the famous wine regions in southern France.

As much as 86 per cent of all production in the regions of Bordeaux and the Rhône Valley, is set to be wiped out within less than four decades, according to a study published in the American ‘Proceedings of the National Academy of Sciences’.

According to the report, which tested four climate change models, the changes predicted by 2050 will offset the delicate balance required to cultivate wine grapes, and could render almost all vineyards worthless in the ‘Bordelais’ and ‘Vallée du Rhône’ areas.

It’s a shocking finding, and one which appears to have surprised even the study’s main author, Lee Hannah.

“When we started out, we thought this was science fiction and now we are pretty sure it is science fact,” Hannah was quoted as saying by French financial daily Les Echos.

However, while the demise of France’s trademark Bordeaux and Côtes du Rhône brands is a sad prospect, wine-lovers could well get to sample the birth and growth of entirely new regional labels, as production moves north.

As the average temperature increases by between 2.5 and 4.7° C, “southern France will see a lot of declining suitability,” Hannah told AFP.

One wine expert is taking a positive view of the predicted changes to the wine-making map.

"Some people are alarmists, I prefer to be an optimist. I have no doubt that we will still have vineyards in traditional regions, but we have to think of new strategies. And we will also have new zones for vineyards. That's for sure," Fernando Zamora, a specialist wine researcher, told AFP.

Massive hornet-trapping campaign begins in south west France

Across south west France trapping campaigns have begun in an attempt to control the numbers of dangerous Asian hornets.

Massive hornet-trapping campaign begins in south west France

Trapping campaigns are organised annually at this time of year, as the weather begins to get warmer and queens begin to emerge from hibernation.

And the Charente-Maritime town of Royan Atlantique, on France’s west coast, is leading the way, as the below video shows.

Experts say that now is the time to begin using the traps, as catching queen hornets in the process of building their nests will lead to far fewer insects later in the year. 

Some 2,000 traps are installed in and around Royan this year, including 300 that were distributed to householders in the week of Valentine’s Day. 

Once installed, the traps can capture several dozen insects at a time.

In order to capture a maximum of hornet queens, traps should be installed between mid-February and mid-May. Especially since during this period, these predators end up coming out of their hibernation.

It is believed Asian hornets arrived in France around 2004. They have now spread nationwide.

Although their venom is not more powerful than that of normal bees or wasps, they are known to be more aggressive towards humans, and their stings can cause anaphylactic shock in allergic people.

The hornets also damage beehives and kill bees, damaging honey stocks and destroying the native ecosystem.
