Article
Nitrogen (N) losses in agroecosystems are a major environmental and economic issue. This issue is particularly pronounced in oil palm cultivation because oil palm production area is expected to increase to 12 Mha by 2050. N fertilization in oil palm plantations is mainly provided by mineral fertilizers, palm oil mill by-products, and biological fix...
Article
Oil palm cultivation has environmental impacts, including those associated with nitrogen (N) losses. Improving management practices to optimise yield and N losses is critical. In order to identify the key management and site parameters driving yield and N losses, over a 25-year cycle, we undertook a Morris’s sensitivity analysis of the Agricultural...
Article
The agriculture, forestry and other land use sector are responsible for 24% (10–12 Pg CO2e per year) of anthropogenic greenhouse gas (GHG) emissions worldwide, with concomitant opportunities for mitigation. A scientific panel used deliberative methods to identify ten technical measures comprising 26 sub-measures to reduce GHG emissions from agricul...
Article
Oil palm, Elaeis guineensis Jacq., is currently cultivated on 19 M ha and palm oil represents more than one‐third of the global vegetable oil market. Addition of nitrogen via legume cover crop and fertilizers is a common practice in industrial oil palm plantations. Part of this added nitrogen is prone to loss from the field, contributing significan...
Article
Although omnipresent in Russian, then Soviet, and finally post-Soviet agrarian history, the village plot has often been described as a residue of the past, destined for impending disappearance. However, it is still alive, especially in the Ukrainian countryside where it sustains five million rural households while ensuring a significant share of na...
Article
Cowpea is an important grain legume crop in Africa. Cowpea flowers are capable of self‐fertilization, which might be the most frequent type of reproduction. Nevertheless, the rate of cross‐pollination could vary between 1% and 10%, depending on the populations of bumblebees or domestic bees that are present, the climate and the cultivar. The aim of...
Technical Report
Full-text available
In this technical report, we describe thoroughly the structure and functioning of the agri-environmental indicator IN-Palm, to assess potential N losses in oil palm plantations (Pardon et al. 2019). It includes the user instructions, an explanation of the use of fuzzy decision trees in IN-Palm, the structure and calculation of the 17 modules of t...
Article
Full-text available
Predicting the fertilizer requirements of an oil palm plantation has long been a difficult task. Two main methods have emerged. Leaf analyses (LA) were used for fertilization management as early as the 1950s. Leaf contents are compared to optimum references, making it possible to adjust the fertilizer rates applied in each block. Another approach,...

Identifying optimal fertilizer management to ensure high nutrient use efficiency is important to reduce negative environmental impacts in oil palm (Elaeis guineensis) cultivation. A 4-year fertilizer trial was established in an oil palm plantation, located at a sandy area with occasional monthly water deficit in Central Kalimantan. We examined the...

We developed IN-Palm, a model to help managers and scientists to estimate N losses to the environment and identify best management practices.
Thesis
Improving palm oil production sustainability is crucial for both reducing negative environmental impacts and ensuring food security. The application of nitrogen fertilisers is a major source of environmental impacts associated with oil palm cultivation. Environmental assessments of palm oil production tend to be uncertain as there is no model speci...

Article
Quantifying the environmental impact of production systems has become a milestone for agricultural commodity chains. Life Cycle Assessment (LCA) is a unique ISO standardized methodology for estimating the environmental impact of human activities along a commodity chain. In the last decade, LCA has become the worldwide standard for environmental pro...

Oil palm is the most rapidly expanding tropical perennial crop. Its cultivation raises environmental concerns, notably related to the use of nitrogen (N) fertilisers and the associated pollution and greenhouse gas emissions. While numerous and diverse models exist to estimate N losses from agriculture, very few are currently available for tropical...

Oil palm cultivation area is expected to increase until at least 2050. This expansion raises environmental concerns, not only regarding land-use change and its consequences, but also concerning potential impacts of losses of nitrogen such as ammonia volatilisation, nitrous oxide emission and nitrate leaching and runoff. The prerequisite to any work...

N2O emissions from agriculture greatly contribute to climate change. In palm plantations on mineral soils, these emissions are mostly due to fertiliser inputs. This raises environmental concerns as oil palm is the most rapidly expanding tropical perennial crop. There is hence a critical need to quantify and model N2O emissions in order to explore s...

Palm oil represents 38% of the world plant oil production. Nitrogen losses are the main cause of pollution during the cultivation period of oil palm. We need to better estimate losses to reduce them. The main challenges that we identified for modelling are: to adapt emission factors to tropical context, to take into account important internal fluxe...

In Europe, agriculture is responsible for 10.2% of greenhouse gas (GHG) emissions. The objective of this study was to assess technical measures to reduce GHG emissions at the farm level without reducing production outputs. France was chosen as a case study with a typical intensive and diversified agriculture. Ten measures, split into 26 sub-measure...
Article
Improving the net GHG budget of ruminant livestock systems without a reduction in productivity and economic sustainability, requires effective mitigation options in terms of abatement potential and costs. Grasslands and grassland management have a large potential to mitigate livestock GHG emissions at a low (or even negative) cost. A synthesis of e...

En France, l’agriculture représente environ 20 % du total des émissions de gaz à effet de serre. Cet ouvrage propose dix actions ou pratiques agricoles permettant de les diminuer sans modification lourde des systèmes de production, ni réduction importante de la production. Pour chacune d’entre elles, le potentiel d’atténuation ainsi que les coûts o...

About 20% of French emissions of greenhouse gases (GHG) originate from the agricultural sector. Ten technical measures, split into 26 sub-measures, were proposed to reduce GHG emissions from French agriculture over the period 2010-2030. Their abatement potential and cost for the farmer werecompared. The proposed measures were linked to nitrogen man...

As the principal cause of climate change, reducing net greenhouse gas (GHG) emissions has become a major objective. The agricultural sector will be required to contribute to this objective, along with other economic sectors. But the specific characteristics of agricultural greenhouse gases make them difficult to quantify and control. ADEME (the Fre...

L’agriculture ukrainienne est caractérisée par une très grande hétérogénéité des structures de production et un caractère dual prononcé : d’un côté, les très vastes exploitations de plusieurs milliers d’hectares en grandes cultures qui prennent en location un grand nombre de parcelles (de petite dimension mais réunies en blocs de grande taille) aup...

To develop an agri-environmental indicator for nitrogen losses in oil palm plantations. One of the objectives is to help identifying efficient combinations of management practices to reduce nitrogen losses. One of the challenges is to develop the indicator in a context of lack of available published knowledge.
