Recent predictions of growth in human populations and food supply suggest that there will be a need to substantially increase food production in the near future. One possible approach to meeting this demand, at least in part, is the control of pests and diseases, which currently cause a 30-40% loss in available crop production. In recent years, strategies for controlling pests and diseases have...

recently organic agriculture as a most popular alternative production system has increasingly been considered by scientists, people and policymakers and governments in the world, and many research programs are directed to this sustainable production system. in organic agriculture it is hardly recommended to integrate plant with animal husbandry in agroecosystem. various animal products such as ...

Tissue nutrient supply may be synchronized with endogenous physiological rhythms to optimize animal and human health. Glucose tolerance and insulin sensitivity have endogenous rhythms that are not essentially dependent on food type and eating. Human glucose tolerance declines as day comes into night. Based on such evolutionary findings, large evening meals must be avoided to reduce risks of vis...

The purpose of this review is not to explain autophagy (as clearly there is a plethora of reviews and research papers on the topic) but to provide the autophagy-savvy reader with an overview of the impact of autophagy research on a number of current topics in food biotechnology. To understand this connection, we need to remember that autophagy is, at the end of the day, a type of stress respons...

This paper investigates the direct and indirect impacts of ethanol production on land use, deforestation and food production. A partial equilibrium model of a national economy with two sectors and two regions, one of which includes a residual forest, is developed. It analyses how an exogenous increase in the ethanol price a ects input allocation (land and labor) between sectors (energy crop and...
