Atmospheric concentrations of greenhouse gases CO2, CH4 and N2O have increased since the Industrial Revolution. During the past 260 years, the rise in atmospheric CO2 concentration is mainly due to fossil fuel combustion, but CO2 emissions from artificial deforestation and other land use change is estimated to be half of fossil fuel emissions. On the other hand, soils could be sinks or sources of atmospheric CO2 depending on the land use and management changes (LUMC) in various plant-soil ecosystems. Soil N and its dynamics not only affect plants growth and crops production, but also limit future C sequestration.
Therefore, C and N dynamics affected by LUMC in terrestrial ecosystems contribute not only to the global and local environmental problems, such as global warming, destruction of the ozone layer, acid rain, and eutrophication, but also to the changes in soil fertility and plant productions related to the human sustainable development. As 60% of the population is in Asia, the studies on C and N dynamics by LUMC in East and Southeast Asian countries are important to resolve both environmental problems and human sustainable development.
This special collection aims to introduce recent research on soil C and N dynamics by LUMC in East and Southeast Asian countries to share knowledge on effective measures and executable strategies for efficient LUMC in East and Southeast Asian countries.
