Накратко на български
Емисиите на въглероден диоксид и метан от китайските влажни зони се анализират чрез местни наблюдения и сателитни данни. Това помага за по-доброто разбиране на връзката между тези газове, водния цикъл и промените в климата.

Wetland Emissions of Carbon (CO2 and CH4) in China under Climate Change: Analysis, Development and Implementation
A major research goal is to estimate the atmospheric sources and sinks of carbon dioxide and methane molecules, how these will vary with climate and land use change and investigate their feedbacks on climate. In particular, wetlands have the potential to act as either a source or a sink of carbon. However, climate feedbacks from changes in wetland carbon dioxide fluxes and methane emissions are very uncertain, due to a paucity of observational datasets; a lack of knowledge of the biogeochemical and physical processes linking these molecules and the water cycle in wetlands; uncertain estimations of inundation extent and water table dynamics for regional and global studies and the lack of explicit description of different wetland types in models. The overall objective of the WETCARB project, within the LSCE-PKU consortium, was to improve our understanding of current and future projections of carbon dioxide and methane fluxes of Chinese wetlands, by combining local observations and mechanisms and regional remotely-sensed data into a process based wetland ecosystem model. China was chosen as a study regional because the region has experienced important changes in air temperature and precipitation. Furthermore, wetland extent in China has also been declining at the national scale. From a methodological perspective, although preliminary estimations of carbon budget estimations do exist, regional and national scale estimations of methane and carbon dioxide fluxes from wetlands in China using process-based models are also lacking.

Цел на проекта
Wetlands, fragile ecosystems that play an important role in the global water and carbon cycles, cover a non-negligible part of the terrestrial surface and render numerous services to humankind. Their role as carbon sinks or CO2 and CH4 sources depends on the prevailing hydrological conditions and is sensitive to rising atmospheric CO2 concentrations, regional climate change, as well as to water management and land use. Modifications of carbon and water dynamics within wetlands are already detectible and can be expected to amplify during the coming decades. Yet, numerous gaps of knowledge exist concerning their CO2 and CH4 flux quantifications and future dynamics, partly due to scarce global databases, and modelling of these dynamics are still highly uncertain. Focusing on China, where extensive wetlands exist and are projected to undergo vast changes, this project aims to analyse the response of wetland carbon emissions to changing hydrological conditions and atmospheric CO2 concentrations, taking into account contrasted regional land use and water management scenarios. An integrated approach combining measurements of CO2 and CH4 fluxes in numerous wetland types of China with new parameterizations of a dynamic vegetation model coupled with a hydrological model is proposed. The project covers changes occurring through the 20th and 21st centuries. It will be undertaken by the Researcher with two world leading teams in Earth System sciences, bringing in both expertise in modelling the terrestrial carbon cycle, datasets and knowledge of ecological processes. The research will deepen and broaden the Researcher’s competences, build long-term skills and collaborations, promote transfer of knowledge to China and contribute to European excellence and competitiveness. Special attention will be given to disseminating results to both the general public and the non-academic sector through a secondment.
