Agritourism

Have you considered sponsoring a child
Agritourism is a style of vacation in which hospitality is offered on farms. This may include the opportunity to assist with farming tasks during the visit. Agritourism is often practiced in wine growing regions.

Dude ranches offer tourists the chance to work on cattle ranches and sometimes include cattle drives.

Agritourism has often been proposed as a means to prop up a local agricultural economy when local producers are no longer economically competitive otherwise.
