Résumé
Increased demand for biofuels is expected to produce changes in the present land-use configuration. Furthermore there is a growing concern about the effect of land-use change on biodiversity, food supply, soil and water quality. Biofuels production on current land and use of biomass in a given region can induce displacement of activities and land-use changes elsewhere. This effect is known as indirect land-use change (ILUC). Due to changes in the carbon stock of the soil and the biomass, indirect land-use change has consequences in the GHG balance of a biofuel.

Indirect land use change impacts of biofuels
The indirect land use change impacts of biofuels, also known as ILUC or iLUC (pronounced as i-luck), relates to the unintended consequence of releasing more carbon emissions due to land-use changes around the world induced by the expansion of croplands for ethanol or biodiesel production in response to the increased global demand for biofuels. As farmers worldwide respond to higher crop prices in order to maintain the global food supply-and-demand balance, pristine lands are cleared to replace the food crops that were diverted elsewhere to biofuels' production.
Biocarburant
Un biocarburant est un carburant (combustible liquide ou gazeux) produit à partir de matériaux organiques non fossiles, provenant de la biomasse (c'est le sens du préfixe « bio » dans biocarburant) et qui vient en complément ou en substitution du combustible fossile. Ceux qui sont produits par la filière agricole sont désignés sous le vocable d'agrocarburant.
Sustainable biofuel
Sustainable biofuel is biofuel produced in a sustainable manner. It is not based on petroleum or other fossil fuels. It includes not using plants that are used for food stuff to produce the fuel thus disrupting the world's food supply. Low-carbon fuel standard In 2008, the Roundtable for Sustainable Biofuels released its proposed standards for sustainable biofuels. This includes 12 principles: "Biofuel production shall follow international treaties and national laws regarding such things as air quality, water resources, agricultural practices, labor conditions, and more.

How to avoid the danger of pollutants in Swiss biochar production and use?
The study of pollutants found in biochar and its effects on agricultural soil was conducted in this paper. The aim of the research was to analyse organic and inorganic pollutants found in biochar which either originate from the biomass itself or are formed ...

Devis Tuia, Julia Schmale, Nora Bergner, Ianina Altshuler, Gaston Jean Lenczner, Grace Emma Marsh
Warming in the Arctic is occurring at an accelerated rate compared to the rest of the world which is partially driven by ecological and climatic feedback loops. Accelerated glacial and ice sheet retreat in Greenland drives increased development of glacial ...
2023Climate-Neutral Aviation: how will it affect communities, companies, citizens?
Science tells us that a climate-responsible aviation is much smaller, given the urgency and limited contribution of future efficiency gains and biofuels. If flying becomes more exceptional and expensive, how can we collectively prepare, and what will this ...
