“…Modeling of agroforestry systems in Europe using the Yield-SAFE (YIeld Estimator for Long-term Design of Silvoarable AgroForestry in Europe) model predicted LER values between 1-1.4 for scenarios in Spain, France, and the Netherlands, indicating higher productivity when integrating trees and crops than when grown separately [100]. In another study in Switzerland, agroforestry models focusing on walnut (Juglans hybrid) and wild cherry (Prunus avium) showed that in 12 out of 14 scenarios, mixing crops led to LER measurements higher than one.…”

Agroforestry—The Next Step in Sustainable and Resilient Agriculture

Agriculture faces the unprecedented task of feeding a world population of 9 billion people by 2050 while simultaneously avoiding harmful environmental and social effects. One effort to meet this challenge has been organic farming, with outcomes that are generally positive. However, a number of challenges remain. Organic yields lag behind those in conventional agriculture, and greenhouse gas emissions and nutrient leaching remain somewhat problematic. In this paper, we examine current organic and conventional agriculture systems and suggest that agroforestry, which is the intentional combination of trees and shrubs with crops or livestock, could be the next step in sustainable agriculture. By implementing systems that mimic nature's functions, agroforestry has the potential to remain productive while supporting a range of ecosystem services. In this paper, we outline the common practices and products of agroforestry as well as beneficial environmental and social effects. We address barriers to agroforestry and explore potential options to alter policies and increase adoption by farmers. We conclude that agroforestry is one of the best land use strategies to contribute to food security while simultaneously limiting environmental degradation.

Abstract. Winarni B, Lahjie AM, Simarangkir B.D.A.S, Yusuf S, Ruslim Y.2017. Tengkawang cultivation model in community forest using agroforestry systems in West Kalimantan,. Tengkawang is the flora mascot of West Kalimantan and has long been supporting the life of people around the forest. Its fruit can be processed into fat which traded as 'green butter', 'borneo tallow', or 'tengkawang oil', which used as cocoa butter substitutes and the material for manufacturing lipstick, candle and drugs. Its wood was used as raw material for sawmill and plywood industries. Today, tengkawang tree existence is endangered and has been replaced with rubber plantations. The purposes of this research were to: (i) analyze the maximum growth increment of tengkawang; (ii) analyze the maximum production of tengkawang fruits and latex; (iii) analyze the financial feasibility of tengkawang cultivation and tengkawang combined with rubber; and (iv)formulate tengkawang cultivation model. The research used a descriptive method in survey form and interview technique by using questionnaire. The research result showed that the maximum growth increment of tengkawang which cultivated in monoculture (model 1) and tengkawang combined with rubber (model 2) were achieved at the age of 40 years. The maximum production of tengkawang fruit in model 1 and model 2 were achieved at the age of 64 years, while the maximum production of latex (model 2) was achieved at the age of 17 years. The cultivation of tengkawang by model 1 produced IRR of 12.3% and model 2 produced IRR of 12.9%. Financially, both cultivation models of tengkawang were feasible to be cultivated. Financially, tengkawang cultivation by using rubber in an agroforestry system was more profitable than tengkawang cultivation in monoculture.

“…L' ensemble de la parcelle profite alors des bénéfices agroenvironnementaux liés aux arbres. Les systèmes de culture intercalaire peuvent de plus générer des revenus diversifiés liés à la production de bois (bois d' oeuvre et biomasse) (Graves et al 2007) tout en rédui-sant certaines charges (économies en intrants) (Thevathasan et Gordon 2004, Malézieux et al 2009). Ils permettent ainsi une production intégrée et économiquement rentable.…”

RésuméLa présente analyse établit un parallèle entre l'agroforesterie française et québécoise en fonction de cinq enjeux fondamentaux : reconnaissance, interdisciplinarité et approche collective ; acquisition et transfert de connaissances ; statut, régle-mentations et financement ; sensibilisation et mobilisation ; support technique et mise en oeuvre sur le terrain. L'information de base provient notamment d'un forum sur l'agroforesterie réalisé par le Centre de référence en agriculture et agroalimentaire du Québec en mars 2010. Principalement pour des raisons environnementales, les haies et les bandes riveraines arborées tendent à se généraliser ; pour leur part, les systèmes agrosylvicoles demeurent moins répandus. Alors qu' en France, la reconnaissance politique est acquise et que de nombreux freins réglementaires ont été levés, au Québec, le statut de l'arbre hors forêt est encore flou, la réglementation restrictive et les programmes non adaptés. Les systèmes agroforestiers fournissent de multiples services écosystémiques, mais un travail reste à accomplir pour les quantifier et pour établir leur potentiel de production agricole et ligneuse.Mots clés : agroforesterie, bande riveraine arborée, haie brise-vent, agrosylviculture, culture intercalaire, stratégie de déve-loppement, France, Québec AbstRActThis analysis draws a parallel between France and Quebec agroforestry in terms of five fundamental issues: recognition, interdisciplinarity and collective approach; knowledge acquisition and transfer; status, regulations and funding; awareness and engagement; and technical support and field implementation. For Quebec, the basic information is taken from an agroforestry forum held by the Centre de référence en agriculture et agroalimentaire du Québec in March 2010. Windbreaks and tree riparian buffers are becoming increasingly common, mainly for environmental reasons, while silvoarable systems remain less common. In France political recognition has been achieved and a number of regulatory restrictions have been lifted; however, in Quebec the status of trees outside forests remains unclear, regulations are restrictive and programs are ill suited. Agroforestry systems perform many ecosystem services, but work remains to be done to quantify them and determine their potential in terms of agricultural and timber production.
