Discussions with four focus groups and interviews with 25 landowners and tenants confirmed the prevailing belief that land rental in Iowa adds a major obstacle to the adoption of sustainable practices. Because of the extremely competitive market for rented land, tenants said they are reluctant even to suggest alternative practices. Other factors included lack of information on profitability of sustainable agriculture, uncertainty due to one-year leasing arrangements, and lack of sufficient technical support for sustainable agriculture from Extension. Following the research stage the project developed two publications to help address these obstacles.
In 2002, 51 percent of farmland in Iowa was rented, while nationally that figure was approximately 38 percent (USDA, 2002). Given the prominence of rented and leased land in Iowa and the Midwest, it is important to understand the effect the rental relationship may have on the adoption of sustainable practices.
There is widespread anecdotal evidence that rented land poses special challenges for the adoption of sustainable agriculture in Iowa (and elsewhere in the Midwest). Sustainable techniques of production, including conservation practices and organic methods, require long-term investments in management and sometimes equipment (Gliessman, 1998). The instability of tenure inherent in rental arrangements, communication issues, and conflicting goals for the land, may lead to difficulties in adoption even when one or both parties in the landlord-farmer relationship wishes to implement sustainable techniques (Netting, 1993). However, little research had directly addressed the question of how land rental might affect the adoption of sustainable farming practices. For a more comprehensive review of the existing literature see Carolan et. al., 2004.
This research project examined the social dynamics between landlords, tenants, and agricultural agency professionals in order to better understand how those dynamics affect the adoption of sustainable agricultural methods on rented land. The project then worked with farmers and Extension staff to develop some tools to help landowners and tenants negotiate rental agreements that accommodate sustainable agriculture.
