Agricultural extension

Agricultural extension connects research and practical knowledge with farmers and rural communities through education, advice, and other forms of support. Its approaches aim to improve agricultural production and livelihoods.

Farmer field school: A group-based learning approach in which farmers study crops and farming practices through field observation and experimentation. It puts extension learning in farmers’ fields, where participants test ideas together.
Seaman A. Knapp: An American agricultural educator known for developing demonstration-based methods to promote improved farming practices. His demonstration work helped shape early organized extension in the United States.
K. N. Singh: An Indian agricultural extension scholar associated with research and education in the discipline. His scholarship represents the development of extension education outside its early U.S. institutional setting.
Top-down approach: A decision-making approach in which authority and direction flow from higher levels to lower ones. It contrasts with extension models that let farmers set priorities and shape advice.
Agricultural productivity: The amount of agricultural output produced relative to the land, labor, capital, or other resources used. Improved practices promoted through extension can change output per unit of resources.
Participatory rural appraisal: A set of methods for communities to analyze local conditions and identify priorities using their own knowledge. Extension workers use it to build programs around community-defined needs.
Smith-Lever Act: A 1914 United States law that established cooperative agricultural extension through land-grant universities and the federal government. It created a durable public framework for research-linked extension in the United States.
Everett Rogers: An American communication scholar whose work analyzed how innovations spread through social systems. His framework influenced how extension practitioners think about adoption and communication.
Participatory development: An approach to development that involves affected communities in defining problems, making decisions, and taking action. It offers a broader framework for farmer-led extension than one-way technology transfer.
Food security: A condition in which people have reliable physical and economic access to sufficient, safe, and nutritious food. Extension can support food security by strengthening production and farm livelihoods.
