Light earth is a natural insulating material composed of earth and vegetal fibres. It can be used to insulate existing and new buildings to reduce energy and resources consumption, and excavated earth generation by the construction sector. A pedological database is crossed with suitability thresholds in order to evaluate spatially the availability ...
Les “métaux lourds” dans les sols : comprendre leur distribution naturelle (matériau parental, pédogenèse) pour évaluer correctement les contaminations d'origine humaine.
Diverses méthodes de réhabilitation de sites pollués. Ne rien faire, recouvrir, décaper, immobiliser la pollution, voire l'extraire par des méthodes de phytoremédiation. Un exemple d'action mêlant immobilisation in situ et phytostabilisation.

The OCBIL theory comprises a set of hypotheses to comprehend the biota of old, climatically buffered, infertile landscapes (OCBILs). Here, we review evidence from the literature to evaluate the extent to which this theory could apply to the biodiversity hotspot of New Caledonia. We present geological, pedological and climatic evidence suggesting ho...
Past builders have developed very low-embodied energy construction techniques optimizing the use of local building materials. These techniques are a source of inspiration for modern sustainable building. Unfortunately, this know-how was orally transmitted andwas lost as earth construction fell into disuse during the 20th century in European countri...

Soil is a major carbon pool ruling the global C cycle and in climate change because soil carbon is a source and a sink of atmospheric CO2. Soil organic carbon also controls many beneficial properties such as fertility, aggregate stability and degradation of groundwater pollutants. Therefore mapping soil carbon at landscape scale is needed to define...
