G-FEED: Introducing SCYM

http://www.g-feed.com/2015/05/introducing-scym.html

Global Food, Environment and Economic Dynamics. Monday, May 11, 2015. In the hopes of figuring out how to raise crop yields or farmer incomes around the world, it would be really nice if we had a quick and accurate way of actually measuring yields for individual fields. That has motivated a lot of work over the years on using satellite data, and we have a paper out this week. Describing another step in that direction. Provides more detail, which I won’t bore readers with here. But to give a sen...The fig...

G-FEED: Are yields becoming less or more sensitive to temperature?

http://www.g-feed.com/2013/04/are-yields-becoming-less-or-more.html

Global Food, Environment and Economic Dynamics. Thursday, April 4, 2013. Are yields becoming less or more sensitive to temperature? Third, this is potentially a VERY scale dependent question. Yield at a national scale, for example, can change for a lot of reasons apart from a change in yield variability for individual fields. For example, work by PeterHazell 30 years ago. Finally, there is increased atmospheric CO. Which one would expect to lower impacts of droughts by improving water use efficiency.

G-FEED: Massetti et al. - Part 1 of 3: Convergence in the Effect of Warming on US Agriuclture

http://www.g-feed.com/2013/12/massetti-et-al-part-1-of-3-convergence.html

Global Food, Environment and Economic Dynamics. Tuesday, December 31, 2013. Massetti et al. - Part 1 of 3: Convergence in the Effect of Warming on US Agriuclture. Has posted a new paper. Joined with Robert Mendelsohn. That takes another look at the best climate predictor of farmland prices in the United States. He'll present it at the ASSA meetings in Philadelphia - I have seen him present the paper at the 2013 NBER spring EEE meeting and at the 2013 AERE conference. Massetti et al. argue that averag...

G-FEED: For your weekend viewing pleasure

http://www.g-feed.com/2015/02/for-your-weekend-viewing-pleasure.html

Global Food, Environment and Economic Dynamics. Friday, February 20, 2015. For your weekend viewing pleasure. In case you somehow happened to miss yesterday's "Hadoop World Conference" in San Jose, we bring you the following video of GFEED's own Sol Hsiang - who despite looking very sharp in his suit earpiece/headset thingy, conspicuously fails to use the word "hadoop", and conspicuously fails to get introduced by Obama, as the speaker before him. What does hadoop mean. Subscribe to: Post Comments (Atom).

G-FEED: Siestas and climate change

http://www.g-feed.com/2015/02/siestas-and-climate-change.html

Global Food, Environment and Economic Dynamics. Monday, February 16, 2015. Siestas and climate change. By Vincent Vadez and colleagues discusses some of the ways crop scientists are selecting for this trait. As I’ve mentioned in past posts, it’s a strategy we are trying to evaluate as a possible adaptation to climate change. It probably helps a little, but it’s not clear how much. Overall, maybe the lesson here is the corollary of what Marshall blogged about a few months ago. Greed, Green and Grains.

G-FEED: Crop Insurance and the Disincentive to Adapt to Extreme Heat

http://www.g-feed.com/2015/02/crop-insurance-and-disincentive-to.html

Global Food, Environment and Economic Dynamics. Tuesday, February 10, 2015. Crop Insurance and the Disincentive to Adapt to Extreme Heat. The fraction of total crop insurance premiums that is subsidized by the government greatly increased between 1981-2013, especially following the 1994 Crop Insurance Reform Act as shown in the following graph. Subsidy ratios increased from 20% in the early 1980s to 60% in recent years for both corn and soybeans. Finally, we interact the weather measures with the fractio...

G-FEED: Measuring yields from space

http://www.g-feed.com/2015/02/measuring-yields-from-space.html

Global Food, Environment and Economic Dynamics. Wednesday, February 11, 2015. Measuring yields from space. This post is co-written with Florence Kondylis at the World Bank, and a similar version was also posted over at the World Bank's Development Impact blog. One morning last August a number of economists, engineers, Silicon Valley players, donors, and policymakers met on the UC-Berkeley campus to discuss frontier topics in measuring development outcomes. The idea behind the event. 8211; could hold part...

G-FEED: A flood of crop data, and a study on drought

http://www.g-feed.com/2014/05/a-flood-of-crop-data-and-study-on.html

Global Food, Environment and Economic Dynamics. Thursday, May 1, 2014. A flood of crop data, and a study on drought. As the growing season gets under way in the Midwest, we have a paper out today in Science on yield trends in the region, and the role of drought. The paper is here. And a summary story here. I'll also post a link asap to a pdf for those without access to Science here. There's also a very nice companion piece by Don Ort and Steve Long here. The paper relates to this post a while back.

G-FEED: Discounting Climate Change Under Secular Stagnation

http://www.g-feed.com/2015/04/discounting-climate-change-under.html

Global Food, Environment and Economic Dynamics. Wednesday, April 1, 2015. Discounting Climate Change Under Secular Stagnation. Ben Bernanke, recent former Chair of the Federal Reserve, has a new blog. And he's writing about low interest rates and so-called secular stagnation, a pre-WWII phrase recently resurrected by Larry Summers. The topic is dismal- hey, they're economists! I generally agree with the. Recent critique of secular stagnation by Jim Hamilton, Ethan Harris, Jan Hatzius, and Kenneth West.
