Assessing the economic contributions and benefits of consumer horticulture

Abstract

Consumer horticulture (CH) programming can result in outcomes and impacts at the individual level, such as money saved by reducing inputs, greater return on the landscape investment, healthier plants, and improved quality of life. It may also lead to community-level impacts that provide public value, such as water quality protection, water conservation, and protection of biodiversity. In addition to documenting such outcomes and impacts, it is important to quantify their economic value, connect the value to actions taken by extension audiences, and demonstrate to extension’s stakeholders a return on investment. However, it is difficult to document the economic contributions of consumer horticulture and even more difficult to document the economic impact of consumer horticulture extension programs. CH reaches individuals and communities directly and indirectly through personal gardens and landscapes, indoor flowers and plants, school and community gardens, and horticulture therapy. The economic contributions and benefits of consumer horticulture are challenging to quantify, but can be evaluated using several different strategies, including measuring the consumer dollars spent and the economy driven by consumers’ purchase of gardening supplies and landscape services. A second strategy is to examine the value of consumers’ gardening actions on environmental ecosystem services that support soils and plants, provide food and raw materials, and regulate functions, such as pollination, storm water catchment, water quality preservation, green waste reduction, and wildlife habitat and diversity. A third strategy is to focus on cultural, social, and health system services, such as education, recreation, and therapy, that result in exercise, nutrition, health, and happiness. Using a combination of these strategies, workgroups of Tennessee extension professionals are balancing the feasibility of data collection with the usefulness of the data gathered by developing realistic and robust outcome indicators that will form the basis for local and statewide reporting.
