Water prices for these types of users are much higher than in agriculture
They report their operating acreage , the average water use, and the estimated saving rate by using CIMIS. We have 28 respondents in golf courses with 6,750 acres in total, and 137 respondents in landscape management with 179,000 acres. The total sum is about 21 times the acreage of the equivalent category in the 1996…

Drip irrigation systems are installed and plants are irrigated as necessary
We also became interested in focusing on the vegetated borders between the pocket marshes and the cropland as a potential means to reduce the soil-water nutrient content before it entered the marshes. Therefore, in year two, the lysimeters were moved to the uplands/wetlands interface, at the border of the cropped area. Stations consisting of four…

These approaches are referred to as dynamic characterization in this paper
Reisinger et al. , for example, estimated that the 100-year Absolute Global Warming Potential of CO2 from 2000 to 2100 could decrease by 2 to 36 % under various GHG concentration scenarios. Second, a series of articles have attempted to synchronize the temporal system boundary under which life cycle emissions are taken into account and the…

Diet and regional pesticide use are possible exposure sources
Few studies report levels of pesticide metabolites in children 6- to 24-months old. Median total DAP metabolite levels in the CHAMACOS children at 6, 12, and 24 months of age were lower than levels in 10 crawling infants and 10 toddlers sampled in the Salinas Valley in 2002. These twenty children were from farm worker homes and…

Beliefs on product quality play an important role in shaping consumer demand
Including limitations in growth of harvested area and the impacts of increased growing season temperatures and potential evapotranspiration would inflate all these aid projections. Two hundred million sub-Saharan Africans were undernourished in 2002, and if the observed 1982–2002 trend continues this total may increase to almost 600 million people by 2030.The ‘business as usual’ projected…

Reasons as to why this pattern may exist will be explored in the discussion section
Two-thirds or more of the pistachio and almond fields showed water vapor trends that were in agreement with the wind direction while less than a third of walnut and grape fields did. These differences may be attributable to differences in the crops themselves such as rate of ET or health of the plants, or these…

One challenge of mapping crops is the portability of a methodology across time
The importance of the shorter wavelength blue bands, bordering on the ultraviolet region, suggests that the UV may contain a wealth of crop information concerning characteristics such as wax deposition and metabolites such as flavonoids and phenolics that could be utilized for discrimination ifatmospheric scattering did not inhibit its use. Outside of the visible range, the liquid…

All of the specifications include the soil variables and state by year fixed effects
When these separate effects are added up and the total summed over the 2,860 US counties in our sample, the net effect of the 5 degree increase in temperature and 8% increase in precipitation is to decrease agricultural profits by $1.9 billion, which is 5.3% of the $36.0 billion in annual profits. The predicted change…

Case reports of silicate pneumoconiosis have been reported in farm workers from the central valley of California
There also may be some degree of misclassification of smoker status, as the diagnosis of recent exposure to cigarette smoke was based on the presence of clusters of characteristic smoker’s macrophages in the alveoli adjacent to the respiratory bronchioles. Although not well documented for humans, it is likely that high and prolonged exposure to diesel…

Harvesting fresh asparagus is laborintensive because each spear is hand cut individually
Individual commodities, however, have fared very differently. Between 1990–92 and 2008–10, average U.S. fresh-market asparagus production declined 50%, while fresh-market strawberry production increased 137%. The U.S. produce industry competes with producers in many other countries with lower farm wages, and imports are increasing as a share of U.S. consumption—up 152% for fresh fruit and 109%…
