Short summary
Greenhouse gas from major agricultural systems from the Indo Gangetic Plane has been estimated and compared with the measured data which will help develop regional GHG inventories and the global GHG budget. These data will reduce the uncertainty in global GHG budget which had a large uncertainty due to lack of regional data.

Short summary
Lowland karst aquifers provide important wetland habitat resulting from seasonal flooding on the land surface. This flooding is controlled by surcharging of the karst system, which is very sensitive to changes in rainfall. This study investigates the predicted impacts of climate change on a lowland karst catchment in Ireland and highlights the relative vulnerability to future changing climate conditions of karst systems and any associated wetland habitats.

Short summary
Legacy effects of increased temperature on both nitrogen (N) transformation rates and nitrous oxide (N2O) emissions from permanent temperate grassland soil were evaluated. A new source-partitioning model showed the importance of oxidation of organic N as a source of N2O. Gross organic (and not inorganic) N transformation rates decreased in response to the prior soil warming treatment. This was also reflected in reduced N2O emissions associated with organic N oxidation and denitrification.

Short summary
In this study, the influence of surface water–groundwater interaction on the nutrient flux in a lowland karst catchment in western Ireland was investigated with the aid of alkalinity sampling and a hydrological model. Results indicated that denitrification within a number of ephemeral lakes is the main process reducing nitrogen concentrations within the turloughs, whereas phosphorus loss is thought to occur mostly via sedimentation and subsequent soil deposition.

Short summary
In this study, the nutrient flux occurring within the surface and groundwaters of a lowland karst catchment in western Ireland was investigated with the aid of alkalinity sampling and a hydrological model. Results indicated that while the system is primarily river fed (allogenic), karst derived recharge (autogenic) adds approximately 85% to the total N-load. Results also suggested that nutrient loss processes were occurring within the system during flooded/wet periods.

Short summary
Pesticides are a major pollutant of surface waters. In this study, we assessed how so-called hydraulic shortcuts (e.g. inlet and maintenance shafts of road or field storm drainage systems) influence surface runoff and pesticide transport to Swiss surface waters. The study suggests that transport via hydraulic shortcuts is an important pesticide transport pathway and that current regulations may fall short in addressing this pathway.

Short summary
Lateral carbon fluxes from terrestrial to aquatic systems remain central uncertainties in determining ecosystem carbon balance. This work explores how temperature and hydrology control production and export of dissolved organic carbon (DOC) at the catchment scale. Results illustrate the asynchrony of DOC production, controlled by temperature, and export, governed by flow paths; concentration–discharge relationships are determined by the relative contribution of shallow versus groundwater flow.

Short summary
The purpose of this research was to detect the effect of plastic film mulching (PFM), a widely applied cultivation method, on soil respiration. We found that soil respiration was not only affected by PFM, but it was also affected by irrigation and precipitation, and whether the PFM increases soil respiration compared to a non-mulched field largely depends on precipitation in the field. The result has an important meaning for agricultural carbon sequestration in the context of global warming.

Our current understanding of wildfires on Earth is filled with knowledge gaps. One reason for this is our poor record of fire in natural archives. We open the possibility for speleothems to be "a missing piece to the fire-puzzle". We find by effecting surface evaporation and transpiration rates, wildfires can have a multi-year impact on speleothem, forming dripwater hydrology and chemistry. We open a new avenue for speleothems as potential palaeo-fire archives.

Short summary
Solute concentrations in headwater streams vary with discharge due to changing flow paths through the catchment during precipitation events. A comparison of stream chemistry across three headwater catchments reveals that solute heterogeneity across each landscape controls how different solutes respond to increasing discharge. Solute heterogeneity is at least partially controlled by landscape distributions of vegetation and soil organic matter.

Short summary
Exfiltration of anoxic groundwater containing Fe(II) to surface water is an important mechanism controlling P speciation in the lowland catchments. Due to changes in pH and temperature, the Fe(II) oxidation rates were much lower in winter than in summer. This study also shows a fast transformation of dissolved P to structural P during the initial stage of the Fe oxidation process resulting in low dissolved P concentrations in the surface water throughout the year.

Short summary
Removal efficiency of carbon and nitrogen in constructed wetlands is inconsistent and does not reveal whether the removal processes are from physical attenuation or transformation to other reactive forms. Previous research did not consider "pollution swapping" driven by transformational processes. Herein the biogeochemical dynamics and fate of carbon and nitrogen and their potential impact on the environment, as well as novel ways in which these knowledge gaps may be eliminated, are explored.
