“…We relied upon a recently published evidence and gap map (Miller et al., 2020), which systematically assessed the available literature on impacts of agroforestry on agricultural productivity, ecosystem services, and human well‐being. We used their data extraction record (sup‐0001) and filtered the results for the practice type “Trees integrated with plantation crops” AND “Tropical” OR "Multiple" ecoregions to match the scope of our paper.…”

Agroforestry is widely promoted as a potential solution to address multiple UN Sustainable Development Goals, including Zero Hunger, Responsible Consumption and Production, Climate Action, and Life on Land. Nonetheless, agroforests in the tropics often result from direct forest conversions, displacing rapidly vanishing and highly biodiverse forests with large carbon stocks, causing undesirable trade-offs. Scientists thus debate whether the promotion of agroforestry in tropical landscapes is a sensible policy. So far, this debate typically fails to consider land-use history, that is, whether an agroforest is derived from forest or from open land. Indeed, 57% of papers which we systematically reviewed did not describe the land-use history of focal agroforestry systems. We further find that forest-derived agroforestry supports higher biodiversity than open-land-derived agroforestry but essentially represents a degradation of forest, whereas openland-derived agroforestry rehabilitates formerly forested open land. Based on a conceptual framework, we recommend to (a) promote agroforestry on suitable open land, (b) maintain tree cover in existing forest-derived agroforests, and (c) conserve remaining forests. Land-use history should be incorporated into landuse policy to avoid incentivizing forest degradation and to harness the potential of agroforestry for ecosystem services and biodiversity.

“…We expect to perform several analyses based on the data collected and to summarize results visually and in various written forms to effectively communicate with intended audiences. A final report will present the map as a detailed data set with figures of descriptive statistics derived from the data set, as in [64]. We intend to publish our systematic map in Environmental Evidence and upload the dataset online as an open-access, interactive site, as in [41].…”

Background: Agroforestry bridges the gap that often separates agriculture and forestry by building integrated systems that address both environmental and socioeconomic objectives. Agroforestry can improve the resiliency of agricultural systems and mitigate the impacts of climate change. Existing research suggests that integrating trees on farms can prevent environmental degradation, improve agricultural productivity, increase carbon sequestration, generate cleaner water, and support healthy soil and healthy ecosystems while providing stable incomes and other benefits to human welfare. Although these claims are becoming more widely accepted as the body of agroforestry research increases, systematic understanding of the evidence supporting them remains lacking for high-income countries. This systematic map will address this research need by providing a tool for identifying and visualizing the existing evidence demonstrating the impacts of agroforestry practices and interventions on agricultural productivity, ecosystem services, and human well-being. The results will be useful for informing policy decisions and future research by making the evidence easily accessible and highlighting the gaps in knowledge as well as areas with enough evidence to conduct systematic reviews. Methods: This systematic map will identify, collect, display, and describe available evidence on the impacts of agroforestry on agricultural productivity, ecosystem services, and human well-being in high-income countries. The search strategy will cover 5 primary databases and 24 organizational websites using a pre-defined search string designed to capture studies relating agroforestry practices and interventions to outcomes in high-income countries. The searches will all be conducted in English. We will screen the identified studies for inclusion or exclusion in stages, first on title and abstract and then on full-text. We will collect data from studies included at the full-text stage to form the map and associated database. For inclusion, the study in question must assess the impacts of the deliberate promotion and/or actual integration of woody perennials (trees, shrubs, palms, bamboos, etc.) on the same land management unit as agricultural crops and/or animals.

“…Recently, agroforestry and its suite of associated practices has increased in policy prominence (see, for example, Buttoud et al 2013), and its promotion is one of the central pillars of Land Degradation Neutrality (LDN) investments globally, targeted to reach US$ 14.7 billion by 2021 (Maillard & Cheung, 2016). Despite this substantial interest and investment, little work has been undertaken to rigorously assess the longer-term impacts of agroforestry extension programs and integrated agroforestry systems (Miller et al 2018).…”
