“…Overyielding in agroforestry systems relative to tree and crop monocultures is central to their interest and potential benefits [6,8,16,44]. Potential mechanisms of overyielding include niche complementarity (i.e., interspecific differences in resource utilization), facilitative interactions among species (e.g., species utilize nitrogen fixed by legumes), and reductions in negative plant-soil feedbacks [71][72][73].…”

“…These interactions can lead to both positive and negative effects when mixing trees and crops in agroforestry. In many environments, interaction between trees and crops can result in overyielding in agroforestry compared to tree and crop monocultures [6][7][8]. Agroforestry system design can exploit these benefits to create economic advantages [9][10][11], but requires specific knowledge on the complex tree-crop interactions.…”

Hi-sAFe: A 3D Agroforestry Model for Integrating Dynamic Tree–Crop Interactions

Agroforestry, the intentional integration of trees with crops and/or livestock, can lead to multiple economic and ecological benefits compared to trees and crops/livestock grown separately. Field experimentation has been the primary approach to understanding the tree–crop interactions inherent in agroforestry. However, the number of field experiments has been limited by slow tree maturation and difficulty in obtaining consistent funding. Models have the potential to overcome these hurdles and rapidly advance understanding of agroforestry systems. Hi-sAFe is a mechanistic, biophysical model designed to explore the interactions within agroforestry systems that mix trees with crops. The model couples the pre-existing STICS crop model to a new tree model that includes several plasticity mechanisms responsive to tree–tree and tree–crop competition for light, water, and nitrogen. Monoculture crop and tree systems can also be simulated, enabling calculation of the land equivalent ratio. The model’s 3D and spatially explicit form is key for accurately representing many competition and facilitation processes. Hi-sAFe is a novel tool for exploring agroforestry designs (e.g., tree spacing, crop type, tree row orientation), management strategies (e.g., thinning, branch pruning, root pruning, fertilization, irrigation), and responses to environmental variation (e.g., latitude, climate change, soil depth, soil structure and fertility, fluctuating water table). By improving our understanding of the complex interactions within agroforestry systems, Hi-sAFe can ultimately facilitate adoption of agroforestry as a sustainable land-use practice.

High input costs, environmental degradation and climate change have generated new challenges in the agriculture, horticulture and forestry sector. The objective of this paper is to identify the main horticultural agroforestry systems useful for climate change adaptation and mitigation. Agri-horticulture, Horti-olericulture, Silvi-olericulture, Horti-pasture, Horti/Silvo-medicinal, Horti/Silvo-ornamental, Horti-silviculture, Horti-entomoforestry and Horti-Pisciculture are horticultural agroforestry systems recommended. Agroforestry systems in comparison with monoculture systems, have better use of water, soil and light, can help reduce the application of herbicides, fungicides, pesticides, fertilizers, increasing food security, biodiversity protection and climatic change adaptation. We recommended national politics, subsidies, technical support and credits for global farmers.

“…), facilitative interactions among species (e.g., legumes fix nitrogen that is used by other species), and reductions in negative plant-soil feedbacks (van der Putten et al, 2013;Tilman, 2001;Vandermeer, 1989). Even the simple two-species systems typical of temperate AC can increase land-use efficiency via overyielding by 40% (Graves et al, 2007) to 200% (Dubey, Sharma, Sharma, Sharma, & Kishore, 2016), compared to trees and crops grown separately. When leveraging tree crops rather than timber trees in AC, it is critical to examine overyielding in terms of reproductive yield (i.e., fruits and nuts) rather than woody biomass, as the response of biomass and fruit yields can be very different when mixing tree crops (Rivera, Quigley, & Scheerens, 2004).…”

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.
