    The study assessed the economic performance of marketable ecosystem services (ES) (biomass production) and non-marketable ecosystem services and dis-services (groundwater, nutrient loss, soil loss, carbon sequestration, pollination deficit) in 11 contrasting European landscapes dominated by agroforestry land use compared to business as usual agricultural practice. The productivity and profitability of the farming activities and the associated ES were quantified using environmental modelling and economic valuation. After accounting for labour and machinery costs the financial value of the outputs of Mediterranean agroforestry systems tended to be greater than the corresponding agricultural system; but in Atlantic and Continental regions the agricultural system tended to be more profitable. However, when economic values for the associated ES were included, the relative profitability of agroforestry increased. Agroforestry landscapes: (i) were associated to reduced externalities of pollution from nutrient and soil losses, and (ii) generated additional benefits from carbon capture and storage and thus generated an overall higher economic gain. Our findings underline how a market system that includes the values of broader ES would result in land use change favouring multifunctional agroforestry. Imposing penalties for dis-services or payments for services would reflect their real world prices and would make agroforestry a more financially profitable system.

    Cross-site analysis of perceived ecosystem service benefits in multifunctional landscapes
    (Elsevier, 2019-05-06) Fagerholm, Nora; Torralba, Mario; Moreno, Gerardo; Girardello, Marco; Herzog, Felix; Aviron, Stephanie; Burgess, Paul; Crous-Duran, Josep; Ferreiro-Domínguez, Nuria; Graves, Anil; Hartel, Tibor; Măcicăsan, Vlad; Kay, Sonja; Pantera, Anastasia; Varga, Anna; Plieninger, Tobias
    Rural development policies in many Organization for Economic Co-operation and Development (OECD) member countries promote sustainable landscape management with the intention of providing multiple ecosystem services (ES). Yet, it remains unclear which ES benefits are perceived in different landscapes and by different people. We present an assessment of ES benefits perceived and mapped by residents (n = 2,301) across 13 multifunctional (deep rural to peri-urban) landscapes in Europe. We identify the most intensively perceived ES benefits, their spatial patterns, and the respondent and landscape characteristics that determine ES benefit perception. We find outdoor recreation, aesthetic values and social interactions are the key ES benefits at local scales. Settlement areas are ES benefit hotspots but many benefits are also related to forests, waters and mosaic landscapes. We find some ES benefits (e.g. culture and heritage values) are spatially clustered, while many others (e.g. aesthetic values) are dispersed. ES benefit perception is linked to people’s relationship with and accessibility to a landscape. Our study discusses how a local perspective can contribute to the development of contextualized and socially acceptable policies for sustainable ES management. We also address conceptual confusion in ES framework and present argumentation regarding the links from services to benefits, and from benefits to different types of values.

    Do European agroforestry systems enhance biodiversity and ecosystem services? A meta-analysis
    (Elsevier, 2016-08-16) Torralba, Mario; Fagerholm, Nora; Burgess, Paul J.; Moreno, G.; Plieninger, Tobias
    Agroforestry has been proposed as a sustainable agricultural system over conventional agriculture and forestry, conserving biodiversity and enhancing ecosystem service provision while not compromising productivity. However, the available evidence for the societal benefits of agroforestry is fragmented and does often not integrate diverse ecosystem services into the assessment. To upscale existing case-study insights to the European level, we conducted a meta-analysis on the effects of agroforestry on ecosystem service provision and on biodiversity levels. From 53 publications we extracted a total of 365 comparisons that were selected for the meta-analysis. Results revealed an overall positive effect of agroforestry (effect size = 0.454, p < 0.01) over conventional agriculture and forestry. However, results were heterogeneous, with differences among the types of agroforestry practices and ecosystem services assessed. Erosion control, biodiversity, and soil fertility are enhanced by agroforestry while there is no clear effect on provisioning services. The effect of agroforestry on biomass production is negative. Comparisons between agroforestry types and reference land-uses showed that both silvopastoral and silvoarable systems increase ecosystem service provision and biodiversity, especially when compared with forestry land. Mediterranean tree plantation systems should be especially targeted as soil erosion could be highly reduced while soil fertility increased. We conclude that agroforestry can enhance biodiversity and ecosystem service provision relative to conventional agriculture and forestry in Europe and could be a strategically beneficial land use in rural planning if its inherent complexity is considered in policy measures.

    Mixtures of forest and agroforestry alleviate trade-offs between ecosystem services in European rural landscapes
    (Elsevier, 2021-06-17) Rolo, Victor; Roces-Díaz, José V.; Torralba, Mario; Kay, Sonja; Fagerholm, Nora; Aviron, Stephanie; Burgess, Paul; Crous-Duran, Josep; Ferreiro-Domínguez, Nuria; Graves, Anil; Hartel, Tibor; Mantzanas, Konstantinos; Mosquera-Losada, María Rosa; Palma, João H.

    Rural Europe encompasses a variety of landscapes with differing levels of forest, agriculture, and agroforestry that can deliver multiple ecosystem services (ES). Whilst provisioning and regulating ES associated with individual land covers are comparatively well studied, less is known about the associated cultural ES. Only seldom are provisioning, regulating, and cultural ES investigated together to evaluate how they contribute to multifunctionality. In this study we combined biophysical and sociocultural approaches to assess how different landscapes (dominated by forest, agriculture or agroforestry) and landscape characteristics (i.e. remoteness and landscape diversity) drive spatial associations of ES (i.e. synergies, trade-offs and bundles). We analysed data of: i) seven provisioning and regulating ES (spatially modelled), and; ii) six cultural ES (derived from participatory mapping data) in 12 study sites across four different biogeographical regions of Europe. Our results showed highly differentiated ES profiles for landscapes associated to a specific land cover, with agroforestry generally providing higher cultural ES than forest and agriculture. We found a positive relationship between the proportion of forest in a landscape and provisioning and regulating ES, whilst agriculture showed negative relationships. We found four distinct bundles of ES. Three of them were directly related to a dominant land cover and the fourth to a mixture of forest and agroforestry that was associated with high social value. The latter bundle was related to zones close to urban areas and roads and medium to high landscape diversity. These findings suggest that agroforestry should be prioritised over other land covers in such areas as it delivers a suite of multiple ES, provided it is close to urban areas or roads. Our results also illustrate the importance and application of including people’s perception in the assessment of ES associations and highlight the relevance of developing integrated analyses of ES to inform landscape management decisions.
