9228179492SubsidyGovernment payment to encourage or protect a certain economic activity0
9228182030Domestic Subsidya payment or tax break made by a government to firms in a particular industry based on production1
9228183825Export Subsidya payment or tax break from a government to firms as a reward for exporting products2
9228185765NutrientsMolecules in food that your body needs to grow, to repair itself, and to supply you with energy (general categories: water, carbohydrates/sugars, proteins/amino acids, lipids/fats, vitamins, and minerals)3
9228185766calorieAmount of energy needed to raise the temperature of 1 gram of water by 1 degree C4
9228188573Food Caloriea unit equal to 1000 calories used to measure the energy in foods; 1 kcal5
9228192404Marasmustotal malnutrition and emaciation (especially in children) due to insufficient caloric & nutrient intake6
9228193992Kwashiorkorprotein deficiency characterized by edema, growth failure, and muscle wasting; a form of malnourishment7
9228244960Bt corna strain of corn that has been genetically engineered to produce a toxin* that kills the corn borer work and insects which attack it *[Advanced detail- optional]: a toxic protein coded for by a gene naturally found in the bacterium bacillus thuringiensis, hence the abbreviation "Bt"8
9228244961Roundup Ready CropsPlants grown from genetically modified seeds that have a genetic resistance glyphosate (an herbicide*) *[Advanced detail]: The multi-national corporation Monsanto is the producer of the Roundup herbicide as well as the Roundup Ready seeds9
9228276561GlyphosateA broad-spectrum organophosphate herbicide that blocks protein synthesis* in plants; it is the active ingredient in Roundup *[Advanced details- optional]; Glyphosate inhibits the production of a specific enzyme called EPSP synthase. Without this enzyme, plants are unable to synthesize amino acids needed to produce other proteins essential to photosynthesis, therefore the plants cannot grow.10
9228369396OrganophosphatesThe phosphorous-containing synthetic chemical basis of many insecticides, herbicides, and nerve agents initially used in chemical warfare*; it's acutely toxic but degrades readily. *[Advanced details- optional]: blocks acetylcholine esterase, thereby increasing both the level and duration of action of the neurotransmitter acetylcholine (resulting in disruption of the parasympathetic nervous system- salivation, crying, vomiting- and muscle spasms); high exposure can lead to paralysis11
9229550247Chlorinated hydrocarbonsThe highly persistent chlorine-containing synthetic chemical basis of many insecticides including DDT (illegal in US for crop use), chlordane and lindane12
9229596267Fair tradeAn international method of trade which aims to ensure that producers receive a fair price for their output, especially in less developed countries (LDCs)13
9229606046Monoculturefarming strategy in which large fields are planted with a single crop, year after year14
9229607402PolycultureAn agricultural method in which several types of crops are planted together in the same field15
9229607403Integrated Pest ManagementAn agricultural practice that uses a variety of techniques designed to minimize pesticide inputs such as polyculture, natural predators, traps, among other to eliminate pests16
9229627279Subsistence agricultureLevel of farming in which a person raises only enough food to feed his or her family17
9229628672Sustainable agricultureFarming methods that preserve long term productivity of land and minimize pollution18
9229630631Industrialized agricultureform of agriculture that uses large-scale mechanization and fossil fuels to boost yields19
