The environmental acceptability of landfill as a waste disposal option depends on the prevention of uncontrolled emission of gas and leachate. With increasingly strict legislation governing the operation and monitoring of landfills and with progressively more emphasis on the controlled biodegradation of waste, a robust understanding of the physical and bio-chemical processes taking place within landfills is essential. Geophysical techniques are already playing an important part in achieving this understanding, both with the installation of below liner leak detection systems, and as a tool for tracking changes in water content in landfills (e.g. Guerin et al 2004; Rosqvist et al 2005).
This paper investigates the efficacy of time-lapse electrical imaging using surface electrodes to monitor the movement of leachate within waste material. The study offered a rare opportunity to monitor a leachate drainage programme over an 18 month period, and was coupled with an extensive hydrogeological monitoring regime, which provided essential comparative results. The time-lapse imaging results and the results from the monitoring wells support a conceptual model whereby the pore pressure in the waste material has reduced, but little or no desaturation has occurred. . Further investigation into the resolution of the electrical imaging method in this setting provides a more robust interpretation of the results.

Die innerstaatliche Umsetzung des Pariser Klimaschutzübereinkommens

Like all public international law treaties, the Paris Climate Accords rely on national law for their implementation. The success of the agreement therefore depends, to a large extent, on the stepstaken or not taken by national governments and legislators as well as on the instruments and mechanisms chosen for this task. Against this background, the present article compares different approaches to the implementation of the Paris Agreement, using court decisions as a means to assess their (legal) effectiveness.
