Agricultural Production Systems & Agribusiness
Agricultural development includes technological and institutional change as factors endogenous to the economic system. Modern agronomy, plant breeding, agrochemicals such as pesticides and fertilizers, and technological developments have in many cases sharply increased yields from cultivation, but at the same time have caused widespread ecological damage and negative human health effects. Selective breeding and modern practices in animal husbandry have similarly increased the output of meat, but have raised concerns about animal welfare and the health effects of the antibiotics, growth hormones, and other chemicals commonly used in industrial meat production. Genetically modified organisms are an increasing component of agriculture, although they are banned in several countries. The UN's Food and Agriculture Organization (FAO) operates a section devoted to agribusiness development which seeks to promote food industry growth in developing nations. Examples of agribusinesses include seed and agrichemical producers like Dow Agro Sciences, DuPont, Monsanto, and Syngenta; AB Agri (part of Associated British Foods) animal feeds, biofuels, and micro-ingredients, ADM, grain transport and processing; John Deere, farm machinery producer; Ocean Spray, farmer's cooperative; and Purina Farms, agritourism farm.
