“…A detailed study along two streams in France revealed increasing SOC stocks towards the stream and at wet conditions (Eglin et al 2008) and a study from Canada found thicker organic layers and more SOC in the RF compared to the upland (Hazlett et al 2005). The main reason for increased SOC under wet conditions is that decomposition of organic matter is limited by lack of oxygen, thus soil respiration (CO 2 efflux) decreases when the ground water table is close to the surface (Laine et al 1996;Jungkunst et al 2008).…”

“…The N 2 O emissions peak at intermediate soil moisture and increase at acidic conditions, whereas the CH 4 emissions largely occur at water saturated conditions (Maljanen et al 2003(Maljanen et al , 2009Jungkunst et al 2008;Christiansen, in review). Although wet soil conditions may only prevail in a minor part of a catchment such as the RF area, the emissions are high enough to be important at the catchment or landscape level.…”

“…The increased CH 4 and N 2 O emissions in the RF may be fully compensated by the reduced CO 2 efflux in the RF; however, this observation is based on only a few studies (Laine et al 1996;Jungkunst et al 2008;Jungkunst and Fiedler 2007). Saari et al (2009) recently showed that sedimentation ponds in peatland forest buffers with high N loads can be potential hot spots for N 2 O emissions.…”

Riparian forests (RF) growing along streams, rivers and lakes comprise more than 2% of the forest area in the Nordic countries (considering a 10 m wide zone from the water body). They have special ecological functions in the landscape. They receive water and nutrients from the upslope areas, are important habitats for biodiversity, have large soil carbon stores, but may emit more greenhouse gases (GHG) than the uplands. In this article, we present a review of the environmental services related to water protection, terrestrial biodiversity, carbon storage and greenhouse gas dynamics provided by RF in the Nordic countries. We discuss the benefits and trade-offs when leaving the RF as a buffer against the impacts from upland forest management, in particular the impacts of clear cutting. Forest buffers are effective in protecting water quality and aquatic life, and have positive effects on terrestrial biodiversity, particularly when broader than 40 m, whereas the effect on the greenhouse gas exchange is unclear.

“…In addition, soil moisture also an important factor that strongly influences the turnover, transference and emission of N 2 O (Mummey et al, 1994;Jacinthe et al, 2000;Pihlatie et al, 2004;Jungkunst et al, 2008). Thirteen climate models from the Program for Climate Model Diagnosis and Inter comparison in the IPCC Fourth Assessment Report predicted that the rainfall in China will increase (IPCC, 2007), and the precipitation in North China will increase by 12-18% under the SRES A2 scenario (Jiang et al, 2008).…”

A B S T R A C TThe Chinese steppe is undergoing a drastic increase in nitrogen (N) deposition, and the precipitation in this region is predicted to increase. However, the response of soil N 2 O emissions to the coupling changes of precipitation and N deposition in grassland ecosystem has been seldom discussed. A manipulative field experiment was conducted to investigate the individual and interactive effects of precipitation increase and N deposition on soil

“…Spatial variations in SWC also influence atmospheric processes, such as the cumulus convective rainfall (Pielke 2001). Jungkunst et al (2008) noted that some soil types, such as hydromorphic soils (i.e., soils which formed under prolonged periods of water saturation with seasonal aeration), will likely exhibit a higher climate-change feedback potential than other, wellaerated soils because soil organic matter losses in hydromorphic soils are predicted to be much greater than those from well-aerated soils.…”

Integrated Groundwater Management

Projected global change includes groundwater systems, which are linked with changes in climate over space and time. Consequently, global change affects key aspects of subsurface hydrology (including soil water, deeper vadose zone water, and unconfined and confined aquifer waters), surface-groundwater interactions, and water quality. Research and publications addressing projected climate effects on subsurface water are catching up with surface water studies. Even so, technological advances, new insights and understanding are needed regarding terrestrial-subsurface systems, biophysical process interactions, and feedbacks to atmospheric processes. Importantly, groundwater resources need to be assessed in the context of atmospheric CO 2 enrichment, warming trends and associated changes in intensities and frequencies of wet and dry periods, even though projections in space and time are uncertain. Potential feedbacks of groundwater on the global climate system are largely unknown, but may be stronger than previously assumed. Groundwater has been depleted in many regions, but management of subsurface storage remains an important option to meet the combined demands of agriculture, industry (particularly the energy sector), municipal and domestic water supply, and ecosystems. In many regions, groundwater is central to the water-food-energy-climate nexus. Strategic adaptation to global change must include flexible, integrated groundwater management over many decades. Adaptation itself must be adaptive over time. Further research is needed to improve our understanding of climate and groundwater interactions and to guide integrated groundwater management.
