Dans un contexte de réchauffement climatique, appréhender l'évolution de la hausse du niveau des mers est un enjeu majeur. Pour cela un des éléments clefs est de comprendre l'évolution du cycle hydrologique atmosphérique dans les régions polaires qui influence directement le bilan de masse de surface des calottes Arctique et Antarctique (les deux p...
This paper investigates the perceptions of a diversity of stakeholders supporting smallholders in the eastern Brazilian Amazon about ecosystem services and agricultural practices. Our results come from 30 semi-structured interviews with key stakeholders in two contrasting municipalities in this region (Paragominas and Irituia). We identified 17 dif...
Surface water storage in floodplains and wetlands is poorly known from regional to global scales, in spite of its importance in the hydrological and the carbon balances, as the wet areas are an important water compartment which delays water transfer, modifies the sediment transport through sedimentation and erosion processes, and are a source for g...
Selective logging, fragmentation, and understory fires directly degrade forest structure and composition. However, studies addressing the effects of forest degradation on carbon, water, and energy cycles are scarce. Here, we integrate field observations and high‐resolution remote sensing from airborne lidar to provide realistic initial conditions t...
The anticipation and adaptation of our societies to the upheavals resulting from climate change are today major issues guiding human activities and public action. Nevertheless, the forecast remains a key challenge because of the strong uncertainties that exist and it is essential to continue to progress in understanding the mechanisms behind these ...
Several Andean countries have planned to restore forest cover in degraded land to enhance the provision of multiple ecosystem services in response to international commitments such as the Bonn Challenge. Hydrological services, e.g. water supply, hydrological regulation and erosion mitigation, are particularly important to sustain the life of more t...
Global climatic changes may deeply affect the functioning of Eucalyptus plantations. It is therefore crucial to gain knowledge on the drivers of Eucalyptus productivity, carbon (C) allocation and resource-use efficiency in order to ensure a sustained productivity. These data are key to improve the productivity of Eucalyptus plantations and reduce t...
Water saving techniques, such as alternate wetting and drying (AWD), are becoming a necessity in modern rice farming because of climate change mitigation and growing water use scarcity. Reducing water can vastly reduce methane (CH4) emissions; however, this net climate benefit may be offset by enhanced carbon dioxide (CO2) emissions from soil. The ...
Competition for light in mixed-species plantations is a main limiting factor for tree growth. Understanding the light absorption and light use efficiency for each species at different planting densities and spatial arrangement of trees is essential for improving these plantations management. The study was conducted in Itatinga-SP, Brazil. A complet...
