Ryan (1990). Agricultural revolution, gradual transformation of the traditional agricultural system that began in Britain in the 18th century. An agricultural system is an assemblage of components which are united by some form of interaction and interdependence and which operate within a prescribed boundary to achieve a specified agricultural objective on behalf of the beneficiaries of the system. Some of this ancient lore had been preserved in religious commandments, but the traditional sciences rarely dealt with a subject seemingly considered so commonplace. These attributes are sufficient to make it also a complex system. Dillon, J.L. Agricultural systems are thus inherently stochastic: being dependent on the passage of time, ex ante, their outcomes are uncertain. System structural coefficients: These coefficients identify and quantify linkage relationships (a) among the various parts or elements within each subsystem and (b) between subsystems. A ‘value chain’ in agriculture describes the range of activities and set of actors that bring agricultural product from production in the field to final consumption, wherein at each stage value is added to the product. People use a vast array of agricultural products every day—these range from the clothes we wear to the paper we write on. Communication is another component to agricultural practices. The latter chapter also considers uncertainty as it occurs in farm planning and decision making. Farming Systems of the World, Chatto and Windus, London. Returning to the paddy flow column of Figure 1.3, the system will also generate a second type of output apart from the material one of grain, namely non-material output. Secondly, increase in agricultural incomes would lead to the demand for industrial products and stimulate industrial investment. and J.E. This is because in order for a farmers to know the type of crop they must yield to generate a profit, they need to know the market prices for the types of crops they are growing. They are discussed in Chapter 5. Know more about IITA .

Strictly speaking, time is not a system component; rather it is a dimension in which the system operates. 'Science in the Systems Age: Beyond IE, OR, and MS', Operations Research 21(3): 661-671. Areas of FOCUS. Before examining the elements of a farm-household system in more detail in later chapters it is useful to consider where they lie in relation to each other in the structure of a small mixed farm as exemplified in Figure 1.3.
