Although genetically engineered (GE) products are used around the world, the issue becomes contentious when they are present in our food.

This paper (IP 53) addresses the commonly heard argument that livestock compete with humans for food resources, thus providing support for the continued existence of livestock production.

This paper looks at the history and purpose of the precautionary principle (PP) and examines problems of ambiguity, arbitrary application, and bias against new technologies. Because the publication (IP 52) is especially focused on the need to feed a growing population, the case studies center on agricultural issues such as pesticide use, genetically modified foods, and food irradiation.

Herbicides were developed during the twentieth century to be used with conventional tillage for weed control. Conservation (or minimum) tillage subsequently evolved, which enabled less soil damage when used with herbicides.

Future food, fiber, and fuel demands will not be met by expanding cropland area; continued advances in nutrient use efficiency will moderate increased nutrient demand. With a growing population, dwindling arable land, and an increased demand for biofuels, the world cannot count on an expansion of harvested area to fill the demands of the world’s growing population.

Los herbicidas se desarrollaron durante el siglo XX para su uso con la labranza convencional con el fin de controlar malezas. Posteriormente, evolucionó la labranza de conservación (mínima), que permitió menor daño al suelo cuando se utilizaba con herbicidas.

This paper (IP 50) addresses specific water and land concerns related to animal agriculture. The authors consider issues of water use and water quality associated with the livestock sector and the related environmental and economic impacts.

Energy Issues Affecting Corn/Soybean Systems: Challenges for Sustainable Production (IP 48) speaks to energy issues […]

The purpose of this CAST Issue Paper (IP 47) is to go beyond the generalizations and accusations often associated with the air quality topic. Experts from six universities examine a large amount of data and focus their information and conclusions around the key livestock areas: swine, poultry, dairy, and beef. Their critical analyses look at a wide scope of issues, from greenhouse gas emissions to the logistics of manure storage facilities.

Part 9, “ANIMAL AGRICULTURE’S FUTURE THROUGH BIOTECHNOLOGY.” Animal biotechnology, which includes both genetic engineering and mammalian cloning, has expanded rapidly in recent decades. These technologies already have been applied in biomedical research and now are nearing application within the food system.
