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 …

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 …
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 …
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 …

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 …
The Great Recession reduced weekly hours by 1.3 hours in the hotel sector but not in the other sectors. Thus, for most employed workers in these three sectors, weekly hours remained constant during recessions. This result contrasts with that in the agricultural sector where weekly hours rose substantially during recessions.China’s economic liberalization and structural change …

Based on a field study, Kumar et al.reported that the presence or absence of over-canopy had little effect on the rhizome yield of galangal , a medicinal plant, implying its shade tolerance.Being a shade-tolerant crop, galangal yield remained steady across a wide range of light availability conditions, from full light to a photosynthetic photon flux density as low …
Agricultural farms are extremely pressed to get a rewarding return on their investments which leads to, at times of the year with high workload, farmers not getting much sleep at all.This is confirmed by a farmer who says that since he works so much, some hours are nearly unpaid.Implementing AI in agriculture could potentially mitigate …
Answering these types of questions will help us clarify the root causes of sustainability problems in agriculture.The general vision of scientists and activists for sustainable agriculture is one which reduces environmental degradation, preserves or restores the family farm, and removes contaminants from human consumption. For example, the goals of the California- based Committee for Sustainable …

The results from our IV estimations indicate that both shock types significantly and positively impact pesticide use.Notably, farmers who experience shocks are more likely to use up to 30% more pesticides than non-shock households.Furthermore, pests and diseases also have a significant and positive impact on fertilizer use with the same magnitude.In other words, these types of …
