The degradation of the Andean cloud forest raises strong biological conservation issues and threatens the sustainability of a crucial water resource. The idea that nurse-based restoration can accelerate the recovery of these forests is underexplored, despite its promise as a restoration technique. Recent conceptual models predict that facilitation ...
While there is a large consensus that plant–plant interactions are a crucial component of the response of plant communities to the effects of climate change, available data remain scarce, particularly in alpine systems. This represents an important obstacle to making consistent predictions about the future of plant communities. Here, we review curr...
This paper investigates the robustness of rainfall-runoff models when their parameters are transferred in time. More specifically, we propose an approach to diagnose their ability to simulate water balance on periods with different hydroclimatic characteristics. The testing procedure consists in a series of parameter calibrations over 10 yr periods...
Cet article explore le lien entre paysage et développement durable et ses enjeux théoriques et méthodologiques, en comparant une série de situations régionales représentatives de la diversité de ces montagnes. L'articulation entre la matérialité du paysage et les pratiques des acteurs locaux est abordée en privilégiant successivement deux "entrées"...
Dans la montagne marocaine, les relations entre forestiers et paysans sont principalement analysées en termes d’opposition : entre une approche réglementaire et administrative d’une part, des stratégies paysannes et communautaires de résistance, d’autre part. Cette lecture bipolaire s’avère insuffisante pour appréhender la question forestière dans ...
Silvopastoral systems of the Swiss Jura Mountains serve as a traditional source of forage and timber in the subalpine vegetation belt, but their vulnerability to land-use and climate change puts their future sustainability at stake. In this paper we couple experimental and modelling approaches to assess the impacts of climate change on the pasture-...
Woody plant encroachment in grasslands is a worldwide phenomenon. Despite many studies, the consequences of woody plant encroachment on sub-canopy vegetation and soil properties are still unclear. To better understand the impacts of trees on grassland properties we examined the following questions using a mountainous sub-tropical grassland of South...
