What is diffusion in agriculture

image

Everett M. Rogers is widely known as the inventor of the “Diffusion of Innovation” theory from his research on how farmers adopt agricultural innovations. Diffusion is defined as the communication process by which a new idea or new product is accepted by the market, while the rate of diffusion is defined as the speed that new idea spreads from one consumer to the next. Adoption, similar to diffusion, also deals with the psychological decision making processes of the individual, rather than those of an aggregate market (Rogers, 2003).

What is diffusion in agriculture?

New technologies are introduced gradually; diffusion is the process through which technologies spread throughout the farm sector over time. While adoption is the decision by an individual producer to use a new technology at a given moment, diffusion is the aggregate measure of adoption decisions. Early studies of diffusion were conducted by sociologists. Rogers (1962) measured technology usage as a fraction of farmers that had adopted a certain technology at a given point in time. Other studies measured diffusion by the fraction of land employed with the new technology. Rogers noticed that diffusion rates of hybrid corn in the United States fit very well as an S-shaped function of time:


What is the difference between adoption and diffusion?

While adoption is the decision by an individual producer to use a new technology at a given moment, diffusion is the aggregate measure of adoption decisions. Early studies of diffusion were conducted by sociologists.


Cultural Influences on Agriculture

Paul Bosland, director of the Chile Pepper Institute at New Mexico State University, talked about how cultural preferences impact what agriculture products are grown in different regions.

What is diffusion of innovations?

The Diffusion of Innovations theory was the leading theory in agricultural extension post World War II until the 1970s. It is still used today in agricultural extension, particularly when extension is concerned with an adoption of a particular technology (i.e. technology transfer approach to extension).


What is the focus of adoption and diffusion?

There are few systematic evaluations of the adoption and diffusion model, research on model does not tend to focus on systemic change (changes to the social system), rather the focus is on discrete technical changes, changes by individuals and groups rather than institutions and societies as a political project.


Who is the founder of diffusion of innovation?

Everett M. Rogers is considered a founder of the Diffusion of Innovations theory. Rogers undertook a PhD (doctoral dissertation) in 1957 analysing the diffusion of several agricultural innovations in a rural community in Iowa. Rogers was convinced that the adoption of innovations follows a universal process of social change.


What is diffusion in biology?

1. What is diffusion? Diffusion is the movement of molecules from a region of higher concentration to a region of lower concentration down the concentration gradient. 2. List the types of diffusion. Diffusion can be divided into two main types, namely, simple diffusion and facilitated diffusion.


What is diffusion in science?

Causes of Diffusion. Diffusion is a natural and physical process, which happens on its own, without stirring or shaking the solutions. Liquid and gases undergo diffusion as the molecules are able to move randomly. The molecules collide with each other and change the direction.


What is the passive movement of molecules across the cell membrane from a region of higher concentration to a region of lower

Facilitated diffusion can be defined as the passive movement of molecules across the cell membrane from a region of higher concentration to a region of lower concentration by means of a carrier molecule.


What is facilitated diffusion?

Facilitated diffusion is a passive movement of molecules across the cell membrane from the region of higher concentration to the region of lower concentration by means of a carrier molecule.


What is the process of movement of molecules under a concentration gradient?

Diffusion is the process of movement of molecules under a concentration gradient. It is an important process occurring in all living beings. Diffusion helps in the movement of substances in and out of the cells. The molecules move from a region of higher concentration to a region of lower concentration until the concentration becomes equal …


How do molecules move from a region of higher concentration to a region of lower concentration?

The molecules move from a region of higher concentration to a region of lower concentration until the concentration becomes equal throughout. Liquid and gases undergo diffusion as the molecules are able to move randomly. Example:


What is the process of moving a substance through a semipermeable membrane?

A process in which the substance moves through a semipermeable membrane or in a solution without any help from transport proteins. For example, bacteria deliver small nutrients, water and oxygen into the cytoplasm through simple diffusion.
