So even taken at face value, the oft - cited
yield gap between conventional and organic farming is smaller than the amount of food we routinely throw away.
Overall, closing
yield gaps by 50 % for crops and 25 % for livestock would lead to a 12 % savings in greenhouse gas emission per calorie produced.
This means that the so -
called yield gap between the potential and actual yield is growing.
Yield gap closure alone still showed a greenhouse gas increase of just over 40 % by 2050.
Due to higher knowledge requirements,
observed yield gaps might further increase if a larger number of farmers would switch to organic practices.
Crop science researchers at the University of Illinois interested in determining and reducing
corn yield gaps are addressing this important issue by taking a systematic approach to the problem.
Closing
rice yield gaps in Asia with reduced environmental footprints (CORIGAP) is a project implemented under the Irrigated Rice Research Consortium (IRRC).
The IRRC continues as a partnership mechanism in GRiSP and serves as a platform for several projects, including the Closing Rice
Yield Gaps in Asia with Reduced Environmental Footprint (CORIGAP).
Related I also recently found a useful resource for anyone looking to focus research on places in the world where the gap between current crop yields and potential yields is greatest: The
Global Yield Gap Atlas.
A $ 2 million project called the Global
Yield Gap Atlas, described in a session here today at the annual meeting of AAAS (which publishes ScienceNOW), is attempting to figure out exactly how much food could be grown on the planet.
Based on our estimates, if all US wheat production were grown organically, an additional 12.4 million hectares (30.6 million acres) would be needed to match 2014 production levels in the U.S., unless the
organic yield gap can be narrowed.
A
shrinking yield gap between U.S. and Canadian two - year notes will also help fuel the loonie's advance, according to Mazen Issa, a senior foreign - exchange strategist at TD in New York.
The analysis used to calibrate next year's index view involves nine different methods, including a normalized
earnings yield gap approach, the P / E Bulls - Eye, currency measures, and consumer confidence, which supports a 1,900 year - end result for the S&P 500 - 4 % above the previously released June 2014 expectation of 1,825.
The varying rates of cooking caused by fewer and weaker breakpoints in the oven leads to
higher yield gaps: where some product on your rack is over cooked and other product is cooked just right.
A recent study from the Illinois Crop Physiology Laboratory, led by Fred Below, a U of I crop physiologist, provides the first estimate of the corn
yield gap for the U.S. Corn Belt.
Given the
glaring yield gaps between rich and poor places, particularly, can campaigners and citizens passionate about environmental conservation (and «green» eating) learn to embrace the need, in many crops and situations, for intensification as a path to a greener, thriving world?
Prior research from England suggests there are complex drivers and impacts of spatial clustering of organic farms that may or may not relate to organic
crop yield gaps [39, 40].
This result is related to a
declining yield gap between irrigated and rain - fed agriculture caused by yield reductions of irrigated crops due to higher temperatures, or yield increases of rain - fed crops due to more precipitation.
«Greater - than - additive management effects key in reducing
corn yield gaps.»
Closing
rice yield gaps in Asia with reduced environmental footprint CORIGAP is a project under the Irrigated Rice Research Consortium (IRRC).
The Closing Rice
Yield Gaps in Asia With Reduced Environmental Footprint (CORIGAP) Project is funded by the Swiss Agency for Development and Cooperation.
The opposite trend was observed for barley (Hordeum vulgare), wheat (Triticum aestevum), and hay crops, however, suggesting the geographical yield potential has an inconsistent effect on the
organic yield gap.
Closing yield gaps and halving food waste still showed a small increase of 2 % in greenhouse gas emissions.
However, there does not appear to be much evidence that the demand for these investments is sufficient to create
a yield gap between green and non-green bonds; tellingly, the province has not attempted to provide any information showing that a yield gap exists.
The yield gap between U.S. 5 - year notes and 30 - year bonds narrowed to 27.20 basis points, the tightest spread in more than six years.
The yield gap was replaced by a funding gap.
As a result,
the yield gap between German government bonds and their U.S. peers widened to multidecade records.
The stock is certainly not risk - free, but such
a yield gap strikes us as more than adequate given the powerful advantages that Google enjoys.
The yield gap between U.S. 5 - year notes and 30 - year bonds narrowed to 27.20 basis points US5US30 = TWEB, the tightest spread in more than six years.
Manufacturers and other stakeholders must find ways to help close
the yield gap that many farmers experience when they transition from conventional to organic, or else risk domestic production of organic crops — and the lower prices they often offer...
Since 2008, IRRI through the HRDC has been promoting hybrid rice research and providing access to new germplasm with the goal of filling in
yield gaps that have been compounded by climate change, and have made rice - consuming populations increasingly vulnerable.
Since 2008, IRRI through its Hybrid Rice Development Consortium (HRDC) has been promoting hybrid rice research and providing access to new germplasm with the goal of filling in
yield gaps that have been compounded by climate change, and have made rice - consuming populations increasingly vulnerable.
The Closing Rice
Yield Gaps in Asia With Reduced Environmental Footprint (CORIGAP) aims to improve food security and gender equity, and alleviate poverty through optimizing productivity and sustainability of irrigated rice production systems.
Proponents have countered that increasing research could reduce
the yield gap, and organic agriculture generates environmental, health and socioeconomic benefits that can't be found with conventional farming.
Another way that industry stakeholders can help close
the yield gap and increase domestic production of organic crops is to actively lobby political representatives to include more funding for organic research in the next Farm Bill, added Melody Meyer, vice president of policy and industry relations at UNFI.
At Clif Bar, the company is tackling
the yield gap by investing in plant breeding, contributing to an agriculture fund that helps provide technical assistance to educate growers and investing in infrastructure that will help reduce the distance that organic producers must transport their crops from the farm gate to the aggregator or processor, which is a significantly longer distance than for most conventional producers, Dillion said.
These techniques shrank
the yield gap to below 10 percent.
In order to quantify the corn
yield gap, which they define as the difference between a farmer's actual yield and the potential yield for that field, researchers studied combinations of five different management factors in corn - following - soybean trials to determine their effect on yield, both individually and cumulatively.
All factors, except for plant population, were necessary for maximizing yield and reducing
the yield gap.
This yield gap has excited much interest from people studying the future of the world's food supply at a time when the explosive growth of the human population needs more, more and even more.
«Closing
the yield gaps is a key part of the solution, particularly in areas with there's a poverty
This isn't the first attempt to model the shortcomings of current agricultural production, called «
yield gaps.»
One scenario investigated by the team is on the supply side: the closing of «
yield gaps».
But even with
the yield gaps closed, projected food demand will still require additional land — so the impact on GHG emissions and biodiversity remains.
Since 2008, IRRI through the HRDC has been promoting hybrid rice research and providing access to new germplasm with the goal of filling in
yield gaps that have been compounded by climate change, and have made rice - consuming populations increasingly vulnerable.
