“…These payments are financed through fees on development, such as roadway expansion, that have unavoidable negative water quality impacts. Likewise, if carbon storage on farmland becomes monetized, agroforestry will be well positioned to generate income through those markets or subsidies as well [10,55,56]. Investment funds seeking positive social and environmental impact are already active in forestry, and the case of Iroquois Valley's investment in Main Street Project here provides an example of how private capital could support MA [57].…”

Agroforestry represents a solution to land degradation by agriculture, but social barriers to wider application of agroforestry persist. More than half of all cropland in the USA is leased rather than owner-operated, and the short terms of most leases preclude agroforestry. Given insufficient research on tenure models appropriate for agroforestry in the USA, the primary objective of this study was to identify examples of farmers practicing agroforestry on land they do not own. We conducted interviews with these farmers, and, in several cases, with landowners, in order to document their tenure arrangements. In some cases, additional parties also played a role, such as farmland investors, a farmer operating an integrated enterprise, and non-profit organizations or public agencies. Our findings include eleven case studies involving diverse entities and forms of cooperation in multi-party agroforestry (MA). MA generally emerged from shared objectives and intensive planning. MA appears to be adaptable to private, investor, institutional, and public landowners, as well as beginning farmers and others seeking land access without ownership. We identify limitations and strategies for further research and development of MA.

“…A wide range of drivers can motivate land owners to establish agroforestry practices on marginal lands, with soil health often a top factor (Mattia, Lovell, & Davis, ). Valuation of C sequestration benefits in AC shows particular promise as an economic driver of adoption in the temperate zone (Winans, Whalen, Rivest, Cogliastro, & Bradley, ). Niu and Duiker () demonstrated that afforestation of marginal lands of the Midwest United States could sequester more than 1,000 Tg C over 50 years.…”

Annual row crops dominate agriculture around the world and have considerable negative environmental impacts, including significant greenhouse gas emissions. Transformative land-use solutions are necessary to mitigate climate change and restore critical ecosystem services. Alley cropping (AC)-the integration of trees with crops-is an agroforestry practice that has been studied as a transformative, multifunctional land-use solution. In the temperate zone, AC has strong potential for climate change mitigation through direct emissions reductions and increases in land-use efficiency via overyielding compared to trees and crops grown separately. In addition, AC provides climate change adaptation potential and ecological benefits by buffering alley crops to weather extremes, diversifying income to hedge financial risk, increasing biodiversity, reducing soil erosion, and improving nutrient- and water-use efficiency. The scope of temperate AC research and application has been largely limited to simple systems that combine one timber tree species with an annual grain. We propose two frontiers in temperate AC that expand this scope and could transform its climate-related benefits: (i) diversification via woody polyculture and (ii) expanded use of tree crops for food and fodder. While AC is ready now for implementation on marginal lands, we discuss key considerations that could enhance the scalability of the two proposed frontiers and catalyze widespread adoption.

“…These measurements were used to calculate tree biomass for this study from the allometric equations of Lambert et al (2005) for hybrid poplars and hardwoods growing in natural forest stands in Canada. Tree biomass was also estimated at both sites in 2014 by Winans et al (2016). At St. Paulin, crop yields were measured at 1.5, 3.5, and 6 m from the tree rows in 2012 (Winans et al 2014) and at 1 and 6 m in 2013.…”

Tree-based intercropping (TBI) may increase carbon (C) sequestration in agroecosystems, but may reduce crop yields. In this study of TBI, we used ecosys, a comprehensive mathematical model of terrestrial ecosystems, which represents interspecific competition for light, nutrients, and water, to evaluate the concurrent effects of TBI on C sequestration and crop yields in TBI experiments conducted at St. Paulin and St. Edouard in southern Quebec. Total gains in C sequestration vs. total losses in crop yields over 11 yr relative to monocropping were 682 vs. 396 g C m −2 at St. Paulin and 841 vs. 168 g C m −2 at St. Edouard. These gains and losses were generally consistent with the measurements at the two TBI sites and with those at TBI experiments under similar environmental conditions elsewhere. Gains and losses depended on competition for light by trees and crops, and so were affected by different fractions of tree foliage removal used to manage this competition in the model. The modelling protocol developed for this study provides a robust, process-based methodology to evaluate economic and environmental benefits of TBI under diverse climates, soils, and tree and crop management practices. Some of the key assumptions used to model TBI are also discussed.
