Micronutrient deficiencies are a significant cause of malnutrition worldwide, particularly in developing countries, affecting nearly 1.8 billion people worldwide. Agriculture is the primary source nutrients for humans, but increasing population and reducing arable lands areas putting agricultural sector under pressure, less developed calls intensive farming to increase crop yield overcome food ...

Subsistence systems in insular Southeast Asia and the western Pacific are geographically patterned: from west to east, grain crops disappear while root and tree crops become more important, and south of the Torres Strait no crops are grown. Previous explanations for these patterns have assumed either a historical cause (the expansion of root and tree crops before grain crops) or some form of en...

biotechnology is providing us with a wide range of options for how we can use agricultural and commercial forestry lands. the cultivation of genetically modified (gm) crops on millions of hectares of lands and their injection into our food chain is a huge global genetic experiment involving all living beings. considering the fast pace of new advances in production of genetically modified crops,...

Genetic engineering provides a means to introduce genes into plants via mechanisms that are different in some respects from classical breeding. A number of commercialized, genetically engineered (GE) varieties, most notably canola, cotton, maize and soybean, were created using this technology, and at present the traits introduced are herbicide and/or pest tolerance. In 2007 these GE crops were ...
