Global Wheat Crop Threatened by Rust Fungus - African Seeds May Offer Hope

You may not have heard of Ug99 yet, but, if its rapid spread continues unchecked, chances are you will not only be hearing about it, but you’ll be paying for it too. That’s because this fast-spreading strain of the fungus that causes stem rust–a seemingly unstoppable plant disease–and is now spreading around the globe and threatening to devastate the world’s wheat harvest.

One hopeful remedy may in fact lay in certain native, durum wheat species (”landraces”) found only in certain African nations–in particular, Ethiopia–which are believed to possess “slow rusting” genes. These native durum wheats are stronger (durum is Latin for “hard”) than7 other strains and originally evolved under much different environmental conditions than European and Western Hemisphere varieties. These durum landraces have most likely evolved slight gene variations as a result. These variations in gene sequences (and/or their expression in the wild), it is believed, can confer survival advantages to the plants when transplanted in a different locale.

Why Africa Needs to Wake Up to Climate Change

Recent pronouncements by the South African President that Africa needs to wake up to the threat of climate change come as a relief in a continent that is likely to suffer the worst effects. Indeed, climate change is compounding Africa’s existing risks and vulnerabilities. In light of this stark reality Africa needs to get up and act.

Exxon Oil and Gas Project to Face Russian Legal Challenge Over Endangered Whales

Russian environmental groups have today launched a legal challenge against a consortium led by U.S. oil and gas giant Exxon, for threatening critically endangered whales in the far east of the country.

Last year, Russian authorities gave Exxon the green light to build a pipeline across a lagoon on Sakhalin Island that is a crucial feeding ground for the world’s last surviving colony of Western Gray Whales.
