Many developing countries implement programs and policies to increase or maintain soil fertility, with the objectives of increased crop yields and decreased poverty. However, few countries give emphasis to the biological management of soil fertility (BMSF) compared to more traditional approaches. Ethiopia emphasizes the use synthetic fertilizers to increase food security and reduce poverty, wit...

The sensation of hunger after a period of fasting and of satiety after eating is crucial to behavioral regulation of food intake, but the biological mechanisms regulating these sensations are incompletely understood. We studied the behavioral and physiological adaptations to fasting in the vinegar fly (Drosophila melanogaster). Here we show that both male and female flies increased their rate o...

Of about 10 billion bushels of corn that are grown each year in the United States, less than 2% is processed directly into food products, and about 18% is processed into intermediates such as high-fructose corn syrup, ethanol, and cornstarch. The vast majority of the annual crop is used domestically for animal feed (60%), and about 16% is exported. Thus, any program for controlling residues of ...

in present world, inequality and uncertainty is high in section of agriculture production and food security of a great amount of people in developing countries is not supplied. based on studies of international organizations, about a third of produced food for human consumption in worldwide is lost or wasted. while in developing countries, there is price enhancement, decrease in access to healt...

West et al.’s recent paper (1) compared tradeoffs of carbon and crop production in temperate and tropical zones. We welcome the empirical evidence in support of agricultural intensification rather than extensification. We strongly caution against the implicit conclusion that food production might need to be concentrated in the temperate zone, however. First, this has implications for food secur...
