Abstract:
Systems and methods for generating a crop yield estimate for an area as small as an individual field from images captured by a satellite are disclosed. The system generates simulations of crop yields in a region that includes the area by applying combinations of different parameters to a crop yield models. Observable quantities for simulated yields are determined from the simulations. The simulations and the observable properties are used to train a statistic model for the region that has two or more variables. Images captured by a satellite that include at least a portion of the area are obtained. Crop information is then determined from the images and weather information associated with the dates that the images where captured is obtained. The statistical model is then applied to the crop information and the weather information to determine a crop yield estimate.

all changes in temperature mean big changes in sweat. To get a sense of how important temperature is, if you go from 25 to 35 Celsius, you more than double the amount of water needed to maintain a given level of growth, says David Lobell, an agricultural ecologist at Stanford University. Because o

Climate change to double costs of making beer, scientists say
Scientists have long known that barley "is one of the most heat-sensitive crops globally," but this study connects that to something that people care about the price of beer so it's valuable, said David Lobell, a Stanford University agriculture ecologist.

USDA Calls Scientist Gag Order a "Misunderstanding"
Im not aware of any such policy in the past, agrees David Lobell, a Stanford University agricultural scientist who examines the impact of rising temperatures on crop yields. Our society deeply depends on good science, and good science depends on open communication. If I were one of [these federa

Stanford scientists combine satellite data and machine learning to map poverty
Co-authors of the study, titled "Combining satellite imagery and machine learning to predict poverty", include Michael Xie from Stanford's Department of Computer Science and David Lobell and W. Matthew Davis from Stanford's School of Earth, Energy and Environmental Sciences and the Cente
According to co-author David Lobell from Stanford University, "The truth is that over a 10- or 20-year period, it depends largely on how fast the Earth warms, and we cannot predict the pace of warming very precisely. So the best we can do is try to determine the odds".
Thanks to the "green revolution" of improved agricultural techniques, crop production is growing about 10 percent per decade and climate change is likely to reduce yields by 1 percent a decade, so crop production will still go up, but not as fast, said David Lobell of Stanford University, one of th
One surprising finding is that overall crop production in the United States has not been affected due to the lack of significant climate trends. "Pretty much the rest of the world in terms of major agriculture producers have seen remarkable warming," David Lobell, of Stanford University's Dept. of E
