Use of Vegetation as Biomaterial for Controlling Measures of Human Impact on the Environment
2019
In a context of a climate change, bioengineering techniques and biomaterials are needed to reduce the human impact on the environment. Thus, in recent years, living materials have been used in environmental engineering applications. In the present paper, attention is restricted to the vegetation, and a brief review on its use as biomaterial in engineering control techniques is presented. The core of this review is a comprehensive overview of two important techniques using vegetation as living material for measures limiting the human impact both in extra-urban and in urban sites. In particular, the use of vegetation both as living material for soil erosion protection and river’s bank stabili…
Detecting human impacts: non-pollen palynomorphs as proxies for human impact on the environment
2021
International audience; Abstract Non-pollen palynomorphs (NPPs) are widely used to detect human activities, in addition to the anthropogenic indicators used in palynology. This paper first tries to determine the best way to approach most probable number (MPN) counting for young scientists. It then looks at the anthropogenic indicators and the different types of human activity that can reveal the studied taxa. Among the different fungal spores, coprophilous fungi are very useful to evidence pastoral activities and grazing pressure. Numerous taxa related to dung are also indicators of decaying organic matter and deserve our attention. Erosion processes due to human activities increase the rep…
