“…In South-East Asia, oil palm expansion has increasingly occurred on peat soils due to land pressure (Afriyanti et al, 2016;Page et al, 2011). Tropical peatland is one of the largest global long-term repositories of terrestrial organic carbon, with the greatest extent (about 247,778 km 2 ) and amount of carbon stored (about 68.5 Gt) in South-East Asia (specifically Indonesia and Malaysia) (Page et al, 2011).…”

-Palm oil is nowadays the first vegetable oil consumed worldwide. Given the world population growth and the increasing demand in fat for food and fuel, the increase in oil palm production is expected to continue. It is thus important to find ways of reducing the ecological impact of oil palm plantations at both the agroecosystem and the mill supply area levels, by improving agricultural practices and land uses. This is where agroecology can play a very critical role. The present article gathers short stories on agroecological practices currently taking place in oil palm plantations in South-East Asia. Such stories notably highlight the importance of the various palm co-products and how appropriate recycling strategies can allow for reducing external inputs to both the field and the mill. Besides limiting environmental impacts thanks to such savings, several coproducts used as organic amendments can even help to maintain or enhance soil quality. Other stories explored agroecological practices developed for biological controls. Although integrated pest management has been applied in palm plantations for a long time, the underlying mechanisms are still not fully deciphered and practices still need to be improved. More knowledge is needed in order to better account for the holistic role of biodiversity and arbitrate trade-offs between practices and ecosystem services, at both plantation and landscape levels.Keywords: palm oil / agroecology / biological control / recycling / composting / soil quality Résumé -Pratiques agroécologiques en plantations de palmier à huile : exemples de terrain. L'huile de palme est aujourd'hui la première huile végétale consommée au monde. Étant donné la croissance démographique mondiale et la demande accrue en corps gras pour l'alimentation et les biocarburants, l'augmentation de la production d'huile de palme devrait perdurer. Il est ainsi primordial de trouver des moyens de production permettant de réduire l'impact écologique des plantations de palmier à huile, à la fois à l'échelle de l'agroécosystème et celle du bassin d'approvisionnement de l'huilerie, en améliorant les pratiques et la gestion des usages des sols. Les principes de l'agroécologie peuvent aider à développer des solutions à ces diverses échelles. Cet article rassemble diverses histoires courtes illustrant des pratiques agroécologiques mises en place dans des plantations de palmier à huile en Asie du Sud-Est. Ces illustrations mettent en évidence l'importance des nombreux co-produits issus du palmier et leur rôle clé dans les stratégies de recyclage pour réduire le recours aux intrants externes pour la plantation comme pour l'huilerie. Au-delà de la réduction des impacts environnementaux du fait de ces économies d'intrants, certains co-produits restitués en plantation peuvent également permettre de maintenir, voire d'améliorer, la qualité des sols. D'autres histoires courtes parcourent quelques autres pratiques agroécologiques dans le domaine de la lutte intégrée. Bien que de nombreuses pratiques de contrôle bi...

“…Some authors have already assessed the potential area for oil palm expansion without deforestation and peat conversion (e.g. Afriyanti et al, 2016). Definitely, the key issue is deforestation, and appropriate strategic land use planning at macro level is mostly needed.…”

“…In Indonesia, which is currently the largest palm oil producer worldwide, the oil palm plantation area increased from 7000 km 2 in 1990 to 110 000 km 2 in 2015 (Ditjenbun, 2015;Tarigan et al, 2016b), and a further 170 000-200 000 km 2 is projected for future oil palm development (Colchester et al, 2006;Wicke et al, 2011;Afriyanti et al, 2016). This rapid expansion of oil palm plantations has been partly triggered by an increased demand for biofuel production (Mukherjee and Sovacoo, 2014).…”

Abstract. In many tropical regions, the rapid expansion of monoculture plantations has led to a sharp decline in forest cover, potentially degrading the ability of watersheds to regulate water flow. Therefore, regional planners need to determine the minimum proportion of forest cover that is required to support adequate ecosystem services in these watersheds. However, to date, there has been little research on this issue, particularly in tropical areas where monoculture plantations are expanding at an alarming rate. Therefore, in this study, we investigated the influence of forest cover and oil palm (Elaeis guineensis) and rubber (Hevea brasiliensis) plantations on the partitioning of rainfall into direct runoff and subsurface flow in a humid, tropical watershed in Jambi Province, Indonesia. To do this, we simulated streamflow with a calibrated Soil and Water Assessment Tool (SWAT) model and observed several watersheds to derive the direct runoff coefficient (C) and baseflow index (BFI). The model had a strong performance, with Nash-Sutcliffe efficiency values of 0.80-0.88 (calibration) and 0.80-0.85 (validation) and percent bias values of −2.9-1.2 (calibration) and 7.0-11.9 (validation). We found that the percentage of forest cover in a watershed was significantly negatively correlated with C and significantly positively correlated with BFI, whereas the rubber and oil palm plantation cover showed the opposite pattern. Our findings also suggested that at least 30 % of the forest cover was required in the study area for sustainable ecosystem services. This study provides new adjusted crop parameter values for monoculture plantations, particularly those that control surface runoff and baseflow processes, and it also describes the quantitative association between forest cover and flow indicators in a watershed, which will help regional planners in determining the minimum proportion of forest and the maximum proportion of plantation to ensure that a watershed can provide adequate ecosystem services.

“…Oil palm expansion in Indonesia and Malaysia has been associated with tropical deforestation (Abood et al, 2015;Gaveau et al, 2016), and expansion of plantations into peat forests has caused large emissions of CO2 (Murdiyarso et al, 2010). If oil palm is to continue its role as the main global source of vegetable oil, then rapid and uncontrolled expansion need to be replaced with intensification and controlled expansion into degraded areas (Corley, 2009a;Smit et al, 2013;Afriyanti et al, 2016).…”
