"In October 2013, Drs. Tim Perkins and Abby van Den Berg of the University of Vermont’s Proctor Maple Research Center
, revealed the findings of a study at a maple syrup conference in New Brunswick, Canada that sent waves through the industry. In 2010, they were studying vacuum systems in sap collection operations. Based on the observation that one of the mature trees in the study that was missing most of its top was still yielding high volumes of sap, they hypothesized that the maples were possibly drawing moisture from the soil and not the crown. Previously, they had presumed that the sap dripping from tap holes was coming from the upper portion of the tree. But, if the tree was missing most of its crown then, they surmised, it must be drawing moisture from the roots. ... They realized that their discovery meant sugarmakers could use saplings, densely planted in open fields, to harvest sap. In other words, it is possible that maple syrup could now be produced as a row crop like every other commercial crop in North America.

Yale's 2010 Environmental Performance Index (EPI)
ranks 163 countries on 25 performance indicators tracked across ten policy categories covering both environmental public health and ecosystem vitality. These indicators provide a gauge at a national government scale of how close countries are to established environmental policy goals.

Pollan for Agriculture Secretary?
It has been suggested (and previously
) that Michael Pollan, author of Second Nature
, The Omnivore's Dilemma
, might make a good Secretary of Agriculture. This would be a dramatic departure for an office that has a decades-long history of steering US agriculture policy to the advantage of the largest agribusiness corporations.
Especially given Obama's potential connections
to Big Corn
, how silly would we be to anticipate real change in US ag policy, relevant as it may be to the economic, energy, climate, and national security issues he campaigned on?

As the global climate changes, agriculture is sure to be affected. The Stern Review
explains that "developing countries - in particular the poorest - are heavily dependent on agriculture, the most climate-sensitive of all economic sectors." Working Group II
of the IPCC
says that: "Smallholder and subsistence farmers, pastoralists and artisanal fisherfolk will suffer complex, localised impacts of climate change (high confidence)." Meanwhile, some important staple crops are especially threatened
by rising temperatures (though genetic engineering may help
). You can experience a taste of it yourself
, with a climate change awareness fast, taking place on Tuesday, September 4th.
