Drought is a common occurrence in Nebraska and agriculture is the primary economic sector affected. Because of repeated and widespread severe drought impacts, more emphasis on drought risk management is warranted. This study develops an agricultural drought risk assessment model using multivariate techniques. The model is specific to corn and soybeans and is able to assess realtime agricultural...

This paper discusses the diverse climate forcings that impact agricultural systems, and contrasts the current paradigm of using global models downscaled to agricultural areas (a top-down approach) with a new paradigm that first assesses the vulnerability of agricultural activities to the spectrum of environmental risk including climate (a bottom-up approach). To illustrate the wide spectrum of ...

Aflatoxins (AFs) are cancerous secondary metabolites produced primarily by Aspergillus flavus and Aspergillus parasiticus in agricultural foodstuff such as peanuts, maize grains, cereals, and animal feeds. Food and Agricultural organization (FAO) estimated that as much as 25% of the world’s agricultural commodities are contaminated with mycotoxins, leading to significant economic losses. Moreov...

Currently Chinese agriculture is facing a serious challenge of the natural risk, market risk and information risk, etc. At the same time, agricultural risk management is under the constraints of concept, capital investment, information sharing, and legal conditions. From the perspective of the information integrated services, this paper made efforts to provide some information and strategy supp...

In agriculture, record profits usually are fleeting; farm booms historically are followed by farm busts. The recent rebound in agriculture’s profitability combined with projections of burgeoning global demand for food, fiber, and fuel suggest the industry has entered a new “golden era.” Still, the glint of banner profits in agriculture could turn out to be fool’s gold. While many in agriculture...

The etiology of non-Hodgkin's lymphoma (NHL) is not well understood. To develop hypotheses on causes of this tumor, data from a population-based case-control interview study of 1,867 white men (622 cases and 1,245 controls) in Iowa and Minnesota conducted during 1980-1983 were examined. Subjects, or their next of kin, were interviewed to obtain information on agricultural exposures, work histor...

The presence of microplastics and nanoplastics (MNPs) in soils is becoming pervasive most agroecosystems. recent estimates suggest that the soil burden MNPs agroecosystems more than 0.5 megatons (Mt) annually. In all agroecosystems, transformation, migration, transferring MNPs, along with other contaminants, trophic transfer can threaten food web. MPs exhibit negative positive effects, or none,...
