DefinitionThe pluralistic extension system is the provision of extension services to a community that is provided by more than one source of extension services (Okorley, Gray, and Reed, 2010). According to Rivera and Alex (2004), a pluralistic extension system can bring together complex providers such as non-governmental organizations, private companies, farmer organizations, individuals, associations of extension specialists and public extension services. extension at the municipal, state and national levels. The non-pluralistic extension system, by definition, is a single provider of extension services managed only by public extension agents. It is clear that the pluralistic extension system does not eliminate public extension agents from the system, but the system adds other potential extension agencies in addition to the existing public extension agency. Why is it necessary? There are several reasons why a pluralistic extension system is necessary. One reason is that the previous single provider extension system, mainly training and visiting (T&V system), was criticized for its limited benefits. As is the case in India, the T&V system has been accused of only boosting commodities and supply, but not generating revenue. This has also been criticized as the cause of falling commodity prices, disintegration of sub-sectors and lack of attention given to the development of farmers' organizations (Singh & Swanson, n.d.). The old extension system was sometimes considered ineffective, having unclear and incompatible state intervention objectives, and vague implementation rules; it also provides limited incentives for extension agents and a lack of financial transparency (Rivera and Alex, 2004). Additionally, the pluralistic extension system is expected to reduce the financial burden on the national government due to the large institutional structures and perceived inefficiency of the old extension system (Swanson & Rajalahti, 2010). The previous extension system has also been criticized for not paying much attention to involving farmers in defining and solving their own problems, while having poor linkage between the extension system, research and farmers (Davis, 2008). Support for farmer groups as a power holder as an extension provider comes from Davis's research in Kenya (n.d.), in which she found that farmer groups were seen by local farmers as a credible source of agricultural information provider (Davis, nd). what are the main dimensions? Rivera and Alex (2004) argue that "extension is not necessarily a government program, but rather a complex set of institutions through which rural people acquire new knowledge and information" (p. 339-340) and enables the possibility of system for extending the differences between different countries. This proposition led to the implication that the extension system dimension (pluralist) could cover a variety of issues such as policy implementation (for change or rural mobilization), information gathering, particularly salient issues (such as health problems: HIV/AIDS, etc...
