Agroforestry offers financial opportunities associated with enhancing the profitability of traditional farming systems (Alavalapati & Mercer, 2004; Campbell et al., 1991; Nair, 1993; Van Vooren et al., 2016). One option is to reduce production costs by decreasing the need for external chemical, water, energy, and/or labor inputs. Another is that agroforestry might increase the net value of production from the nation’s farmlands through optimizing mixtures of primary (e.g., corn, sawlogs, nuts, cattle, etc.) and secondary crops (e.g., mushrooms, Christmas trees, silvopasture‐raised chickens, etc.) as well as ecological services (e.g., carbon sequestration and water quality credits) for which specialty markets have been or are being developed (Van Vooren et al., 2016; de Jalon et al., 2018). Total production might also be enhanced by increasing production from highly erodible or frequently flooded fragile lands without causing severe environmental degradation, for example through the use of tree crops as suggested by Smith (1950).
