Livestock are an important source of both CH4 and N2O emissions in Yolo County

A defined urban boundary that reduces the area of interaction between urban and agricultural landscapes, however, could reduce any potential heat island and runoff effects on agriculture. By leaving larger tracts of agricultural landscapes intact, the interface problems are, to a degree, mitigated.Population expansion in Yolo County, the Sacramento Region, and northern California in general …

For all crops other than rice the fraction of area burned each year was held constant over the study period

Fuel use for irrigation pumping was calculated as the product of the number of diesel‐ powered irrigation pumps in the county, the estimated annual activity of each pump , the average brake horsepower of pump engines in the Yolo/Solano Air Quality Management District, and the brake specific fuel consumption per hour . As of 2003, …

The alluvial plains support a diverse set of irrigated perennial and row crops

The lower metal-humus complexes of Andisols in the present study as compared to Andisols from Réunion Island could be associated with the higher annual rainfall and temperature under tropical conditions that accelerated organic matter decomposition. In our study the negative correlation between soil pH and Fep and Alp was observed indicating favorable conditions for organo-metal complex …

ADDs have the great number of ties coming to and leaving the organization

Participants mentioned that specific technologies or technical messages were often provided to farmers through interaction with the SANE representatives tackle agricultural and climate adaptation challenges with a focus on nutrition-sensitive agriculture. SANE representatives are also members of the NACDC. CGIARs and NACDC have in-degree scores of 4 and 3, respectively. Several participants noted that CGIARs …

New policies should avoid this trap and achieve their objectives without expanding supply

There has been an overall agreement that past policies have been inefficient and that income-support policies “overshot” in assuring and providing food supply and have become too costly and barely affordable. This suggests the need for “decoupling”-setting entitlements criteria that do not affect production while attaining other objectives. Government policies have resulted in substantial excesses …

It is postulated that three major factors have contributed to the observed changes in agricultural employment

Micrographs and panoramic images were taken with an FEI transmission electron microscope at an acceleration voltage of 80 kV with a TVIPS TemCamF416 digital camera using the software EM-MENU . Panoramic images were aligned with the software IMOD.Sharp drops in employment have characterized the economic transition occurring in Central and Eastern Europe. Their persistence has been a surprise to …

The final models were identical using either manual forward selection or backward elimination

Since Mn dust loading is likely to be on the casual pathway for some of our predictors of exposure, such as farm worker shoes in the home and proximity to agricultural use of Mn fungicides, we used a structural equation model to evaluate casual pathways of exposure in the model that included participants with Mn dust …

All remaining voids from the sampling period were pooled prior to analysis

Research staff reviewed the 24-hr sampling record with the parents to ensure accuracy and completeness. Urine samples were stored in the sample refrigerator until daily collection by research staff. Trained, bilingual study staff administered daily questionnaires that assessed the child’s exposure to pesticides, including questions regarding dietary intake of fruits, vegetables, and juices; time spent …

Aggregate measures of production can mask trends in individual crops or crop groups

This is truer than ever now, with pressing fiscal issues preventing the expansion of most federal programs. How, then, can we influence the dietary quality of food stamp recipients, especially given the fact that increased benefits are unlikely to cause recipients to purchase healthier foods? I argue that the answer lies in creating marketplace incentives targeted …

Augmentation of the nutritional quality of crops is also critical for global food security

Specifically, the effect of flood water application frequency on mineralization of organic N to inorganic forms should be investigated to assess the full N loading amount to groundwater under AgMAR. Although our study was exclusively focused on the impact of AgMAR on groundwater nitrate quality, we believe these findings to be applicable to other similar settings, …
