Cropland diversity has diminished with the advent of mechanized agriculture. In some cases, a single crop is grown year after year in the same field. The lack of diversity in crops rotated in a field has allowed pests to build up, reduced yields, and in some cases increased soil erosion and reduced soil quality. Recognizing these problems, efforts are underway in many farming regions to add mor...

Recently, genetically modified (GM) technology has been successfully used to reduce the cost and to enhance the profit in agriculture. Although GM technology brings many benefits for non-food crops, people still misgive the effects of GM products for the health and the environment. Furthermore, GM crops might affect food (non-GM) crops in the open environment. Hence, how to find strategies for ...

Mycotoxins are secondary fungal metabolites that can be produced in crops and other food commodities both pre- and post-harvest. When ingested, mycotoxins may cause a mycotoxicosis which can result in an acute or chronic disease episode. Chronic conditions have a much greater impact, numerically, on human health globally. Reduced growth and development, immunosuppression and cancer are chronic ...

Public forests in central Leyte, Philippines provide an important source of annual food crops, perennial cash crops, and rattan and timber to lowland farmers. Household economic dependence upon and uses made of forest resources are associated with relative access to lowland-based activities, especially production of irrigated rice. Households unable to procure sufficient food staples through on...

Political responses to novel foods and crops can be specific to the new traits of those crops (agronomic versus enhanced nutrients), to the intended uses of those crops (food for people versus feed for animals), and also to the methods used to introduced those traits (conventional breeding versus genetic engineering). This article describes variations in observed political responses to three di...

Intercropping of agricultural crops with woody species is an age-old practice in traditional farming systems in the tropics. Food production is the major aim of subsistence farmers with most of their farmland being allocated to food crops rather than to trees and shrubs. Due to increasing population and scarcity of productive lands that cannot sustain intensive exploitation, one method that has...
