Abstract

Until recently, the massive development of industrial and smallholder oil palm (Elaeis guineensis Jacq.) plantations has generally been conducted according to the monocrop model. However, alternative cropping systems have emerged, based on more diversified systems that combine various crops within the oil palm plots. By giving this plant a status equivalent to that of a tree, these practices correspond to agroforestry systems. In the present study, 39 agroforestry systems were identified worldwide through a preliminary literature review, a review of NGO websites and expert surveys. Our results reveal five different types of oil palm agroforestry systems: (i) associations with livestock during the production phase of the oil palm; (ii) traditional African palm and food crop systems sustained over time; (iii) associations with food crops during the juvenile phase of the oil palm; (iv) systems developed by family farms that permanently associate other plants; and (v) prototype designs developed by research institutions, often at the request of local agricultural enterprises. The spatiotemporal description of these systems enabled us to identify associated ecosystem services. Building on various proposals of biodiversity insertion in a monoculture to convert it into an agroforestry system, the present study offers new perspectives for the sustainable development of palm oil production.

Abstract

Le développement massif des palmeraies industrielles et villageoises s’est réalisé en suivant un dispositif de plantation en culture pure du palmier à huile (Elaeis guineensis Jacq.). Cependant, divers systèmes de culture alternatifs ont émergé, dans lesquels sont associés des cultures et des animaux à diverses phases du cycle de culture du palmier. En attribuant à cette plante un statut équivalent à celui d’un arbre, ces systèmes correspondent à des systèmes agroforestiers. Dans cette étude, trente-neuf systèmes agroforestiers à base de palmier à huile ont été identifiés dans le monde à partir de la littérature, de la consultation de sites internet et d’enquêtes. Cinq types de systèmes agroforestiers ont émergé : i) l’agropastoralisme, correspondant à l’introduction d’élevage pendant la phase productive du cycle de culture du palmier ; ii) l’agroforesterie traditionnelle africaine à base de palmiers et de cultures vivrières ; iii) l’agroforesterie temporaire avec des cultures vivrières en palmeraie juvénile ; iv) l’agroforesterie permanente avec des cultures pérennes ; et enfin v) des prototypes de systèmes agroforestiers à base de palmiers sélectionnés, conçus par des institutions de recherche et développement, souvent à la demande d’entreprises agricoles ou d’agro-industries. La description spatio-temporelle de ces systèmes a permis de mettre en évidence les services écosystémiques rendus par les espèces associées. Diverses perspectives de développement de l’agroforesterie sont discutées en tant qu’alternative aux palmeraies monospécifiques, pour introduire de la biodiversité dans des territoires historiquement spécialisés en élaeiculture, pour initier du développement élaeicole en zones suboptimales, ou encore pour s’adapter au changement climatique.
