1. The hidden half of the meadow : Interactions between drought, soil carbon, roots and soil microbial communities
Abstract : Soil is a hidden ecosystem which harbours plant roots and countless microorganisms, vital for sustaining life aboveground. These belowground communities provide essential ecosystem services like soil stabilisation and organic matter decomposition. READ MORE

2. Novel approaches in modeling of soil carbon : Upscaling theories and energetics
Abstract : Soils contain more carbon (C) than terrestrial (above ground) and atmospheric carbon combined. Mismanagement of soil C could lead to increased greenhouse gas emissions, whereas practices leading to increased C storage would help mitigate climate change while improving soil fertility and ecological functions.

3. Quantity and quality of soil organic matter in permafrost terrain
Abstract : High latitude terrestrial ecosystems are considered key components in the global carbon (C) cycle and hold large reservoirs of soil organic carbon (SOC). Much of this is stored as soil organic matter (SOM) in permafrost soils and peat deposits and is vulnerable to remobilization under future global warming. READ MORE

4. Sustainable agriculture : From global challenges to local land management
Abstract : Despite the success of agriculture management practices in increasing the availability of food needed to meet the requirements of the expanding global population, there are increasing demands placed on the resources on which the sector depends. Opportunities for the development of agricultural systems are constrained by increasing competition, from other sectors, for shared resources. READ MORE

5. High-resolution mapping and spatial variability of soil organic carbon storage in permafrost environments
Abstract : Large amounts of carbon are stored in soils of the northern circumpolar permafrost region. High-resolution mapping of this soil organic carbon (SOC) is important to better understand and predict local to global scale carbon dynamics. READ MORE
