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 …

From the point of view of our exercise, this greater variance produces a ‘bias’ in the resulting estimates of the connection between agricultural income and welfare, since we are interested not in the short-run effect of things like weather shocks on expenditures but on the longer-run effects of things like improvements in agricultural productivity. We are …
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 …

From this perspective, economists often propose that farmers should pay for the real value of the water they use for irrigation. Because of the presence of subsidies, the real value of water in agriculture is different from the price paid by farmers.It is also different from the cost of delivery, which does not account for …
If households are homogeneous in the sense that they engage in a similar income generation and face a similar economic problem, the estimated production function provides quantitative insights on the effects of the mortality on income generation and the decomposition of the effects into productivity and each productive asset. Since productivity includes all heterogeneities among households except those …

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 …

Managing water quality in river and ground water ecosystems is another shared challenge for sustainable agriculture in both the U.S.and South Korea.Water quality is intrinsically tied to water storage levels, stream flow and climate change.When estimating future life-cycle eutrophication, Lee et al.found that eutrophication in the Midwest U.S.stays relatively steady when using the Representative Concentration Pathways …
