For these commodities, the Domestic and Full changes from reference are therefore most similar. Indeed for Corn in particular, the inclusion of even spatially heterogenous, direction varying impacts across the entire world versus only in the U.S. makes very little difference in the physical output variables of GCAM considered: area, production, and endogenous yield. It is primarily …

Pena shows that border enforcement is negatively associated with agricultural worker migration specifically
These efforts to manage groundwater supply and groundwater quality make the agricultural community subject to an evolving set of new requirements for documentation of key farm activities, training, practice improvement, monitoring and reporting. This will be a significant and in some cases expensive shift in farming practices. It is without parallel in California’s agricultural history. …
Switch grass also had poor stand establishment when compared to other grasses
Countries may provide more subsidies if the political accommodations that they buy are especially valuable. Indeed, Table 1 suggests that subsidies are more likely to occur in countries with a major reserve or in authoritarian countries, such as Iran or Venezuela.This research aims to explain the impact of the introduction of bio-fuels on fuel markets …

The challenges facing the Air Resources Board are not completely uncharted
Livestock production is the agricultural sub-sector with the highest emissions and in turn with the highest potential for mitigation finding. It uses approximately 37% of the state’s agricultural land finding, and it generated 61% of California’s agricultural greenhouse gas emissions in 2009. The remaining 63% of agricultural land is used for field, fruit and nut …

Previous meta-analyses have also examined various aspects of N2O emissions from conservation tillage
The large N2O emissions from agricultural lands are of particular concern given both its high global warming potential relative to CH4 and CO2 and its contribution to stratospheric ozone depletion.Conservation tillage, including no-tillage and reduced tillage management, is increasingly being adopted on agricultural lands worldwide.About 10% of global arable lands, i.e.∼125 million hectares, are currently managed using conservation …
How might private and state-owned enterprises differentially affect other markets?
The authors report that the US government had no intentions for the firms other than as investors, and intended from the beginning to sell off the firms.Because subsidies and other soft budget constraints were not applied to these firms, and firm ownership was perceived to be transferrable, efficiency differences between ownership types were likely diminished relative to …
One such simplification will be to focus on a single crop for any given region
The relationships between crop yields, weather and climate have been the focus of a great deal of attention in the Earth system science literature.This is due to concerns about securing food supplies for our growing populations and the potential challenges that climate change poses.Most studies have been concerned with establishing the current relationships between climate …

Gillin provides interesting insight into the importance of water for the people of Moche
In Gillin’s ethnographic account of the town of Moche, he observed that many dishes were cooked or boiled over an open flame, either in ceramic or metal containers placed on an adobe brick stove or on rock supports placed on the ground. Gillin lists a variety of one pot meals, including soups, stews, or gruels, which often …
It is likely that some of these rodents survive baiting by consuming a sub-lethal dose
The higher incidence in the western states may suggest that workers in this region are at higher risk of drift exposure; however, it may also have resulted from better case identification in California and Washington states through their higher staffed surveillance programs, extensive use of workers’ compensation reports in these states, and use of active surveillance …
Individuals working on a resources or database should be named on the website
Distributed and independent genome projects produce assemblies and annotations that can be beneficial to research on related species, if researchers can discover them. However, even a multi-species database that manages gene families may not contain all gene data of interest to the communities it serves. Services that assign new data, supplied by researchers or by …
