Gene Banks to Preserve World’s Crops from Climate Change

In 1992, the Global Biodiversity Convention (GBC) was adopted in Rio de Janeiro, and which placed the biodiversity issue center stage–calling for the world-wide preservation of biodiversity and its equitable and sustainable use. The convention was established in response to both the increasing rate of plant extinction (through habitat loss), fears by poorer nations of “biopiracy”, and the increasing agricultural use of land for high-value crops, to the exclusion of lesser-value ones–a practice that diminishes crop biodiversity. These lesser-value crops are typically grown by independent and small farms in less economically advanced countries. Many of these so-called “orphan crops” risk becoming extinct. Further, many species of plant or tree that fall outside the conventional definition of agriculture–such as the sea-water tolerant mangrove tree–are being ignored, to the possible peril of future agriculture.

Recent warming trends pose the greatest threat to preserving global “agrobiodiversity” due to its predicted alterations in temperature, precipitation, and sea level (thus the intrusion of saline water into fresh water ecosystems). Also, computer models show that global warming will increase the frequency and duration of flood and drought cycles. To protect civilization’s long-term food supply (and to protect against the social chaos of food shortages from consequent crop failures) from these potentially calamitous effects, scientists and agricultural policy experts, in cooperation with various governments, have begun establishing cryogenic gene banks to preserve the seeds of various, valuable crops for future agricultural use. The most notable example of this is the International Rice Research institute (IRRI) in the Philippines which stores over 100,000 strains of rice.

UK Crops To Suffer: Farming Practices to Alter

I’m quite the dreadful snob when it comes to the consumption of alcohol. Whereas the less intellectual types may sit on verandas, sipping red wine, discussing Voltaire, I’m indoors, crate of cheap lager at my side, football on the telly.

Whereas they may swill the grape juice, inhale the aroma and swoon over the subtleties cascading o’er the taste buds, I’m already on my third can and the match yet to start.

But my, how I jolted when I came across a story suggesting that English vineyards may, in decades to come, suffer because our summers are set to become too hot.

Beer Shortages May Be Coming Due to Climate Change

Among the many other ill effects it is causing, global climate change may also be contributing to failures of hops and barley crops. Without these two essential ingredients, the supply of beer will be reduced, and prices for what remains will rise dramatically.

According to Jim Salinger, a climate scientist at New Zealand’s National Institute of Water and Atmospheric Research, the warming globe will likely cause a decline in the production of malting barley, which, when combined with the scarcity of hops right now, stands to have a profound and negative impact on the world’s beer supply starting now, and for decades to come.
