Agricultural Intensification
type: Distribution

media type: text/html
description: (1) Agricultural intensification can be technically defined as an increase in agricultural production per unit of inputs (which may be labour, land, time, fertilizer, seed, feed or cash). For practical purposes, intensification occurs when there is an increase in the total volume of agricultural production that results from a higher productivity of inputs, or agricultural production is maintained while certain inputs are decreased (such as by more effective delivery of smaller amounts of fertilizer, better targeting of plant or animal protection, and mixed or relay cropping on smaller fields). Intensification that takes the form of increased production is most critical when there is a need to expand the food supply, for example during periods of rapid population growth. Intensification that makes more efficient use of inputs may be more critical when environmental problems or social issues are involved. In either case, changes caused by intensification are to be understood conceptually in contrast to extensive adjustments, which involve increases or decreases in the amount of inputs used. Historically, the most common and effective extensive adjustment in agricultural production has been to increase or decrease the area of land planted. (2) An increase in agricultural production per unit of inputs (e.g. labour, land, time, fertilizer, seed, feed, cash). This intensification has been a prerequisite to human civilization. Increased production is critical for expanding food supply; intensification that makes efficient use of inputs is critical for maintaining the health of agricultural environments.

Anthrax
type: Distribution

media type: text/html
description: An ancient zoonotic disease that continues to cause serious illness in livestock, where it is a particular threat to cattle and small ruminants like sheep and goats. It can affect all warm-blooded animals, including humans. Treatment is possible with early diagnosis but often there are no symptoms and infected animals die swiftly. Humans generally acquire the disease directly or indirectly from infected animals or occupational exposure to infected or contaminated animal products. Although many countries have confirmed cases, this is not, in the main, a disease of wealthy countries. Incidences of both animal and human anthrax are frequently associated with conflict.
