Scientific Publishing: the Dilemma of Research Funding Organisations
Present changes in scientific publishing, especially those summarised by the term ‘Open Access' (OA), may ultimately lead to the complete replacement of a reader-paid to an author, or funding-paid, publication system. This transformation would shift the financial burden for scientific publishing from the Research Performing Organisations (RPOs), particularly from scientific libraries, universities, etc, to the Research Funding Organisations (RFOs). The transition phase is difficult; it leads to double funding of OA publications (by subscriptions and author-sponsored OA) and may thus increase the overall costs of scientific publishing. This may explain why - with a few exceptions - RFOs have not been at the forefront of the OA paradigm in the past. In 2008, the General Assembly of EUROHORCs, the European organisation of the heads of research councils, agreed to recommend to its member organisations at least a minimal standard of Open Access based on the Berlin Declaration of 2003 (green way of OA). In the long run, the publishing system needs some fundamental changes to reduce the present costs and to keep up its potential. In order to design a new system, all players have to cooperate and be ready to throw overboard some old traditions, lovable as they may b
Exploring the link between climate change and migration
Previous research has postulated that climate change will lead to mass migration. However, the linkages postulated between the two have not been explicitly demonstrated but have rather been derived from ‘common sense'. In this paper, the connection between climate change and migration via two mechanisms, sea level rise and floods, is investigated and depicted in conceptual models. In both cases, a connection can be traced and the linkages are made explicit. However, the study also clearly shows that the connection is by no means deterministic but depends on numerous factors relating to the vulnerability of the people and the region in questio
Tracers as Essential Tools for the Investigation of Physical and Chemical Processes in Groundwater Systems
In complex environmental systems, tracers are indispensable tools for the investigation of various physical, chemical, and biological processes. From the large variety of tracers employed by EAWAG in the aquatic environment, we present some examples relevant to groundwater research. Some tracers (e.g., 222Rn, 3H/3He, chlorofluorocarbons) allow the time since groundwater infiltration to be determined; this information can be used to quantify process rates such as flow velocities, recharge and reaction rates. Other tracers (e.g., conductivity, isotopes of oxygen or boron) can be used to quantify mixing ratios between waters of different origin, for instance, to study the admixture of leachate from a landfill to an aquifer. In contrast to these inert tracers, chemically reactive tracers (e.g., nitroaromatic compounds) can be used to study subsurface biogeochemical transformation processes, e.g. the reduction of contaminants under anaerobic conditions. The successful use of tracers in the study of environmental systems requires highly developed analytical facilities for a broad palette of tracer measurements and a careful choice of appropriate tracers for each specific problem

Energy forecasting and atmospheric CO2 perspectives: two worlds ignore each other
Macroeconomic models predict that the global primary energy demand will increase by a factor of 2–4 by the year 2050. In contrast, climate analyses made by the IPCC claim that CO2 emissions in 2050 should not exceed the values of 1990 or even be 20% lower. By 2100 emissions should be reduced to one third of the present value. The common wisdom to deal with these opposing trends is the concept of de-carbonization, i.e., the continuous decrease of the carbon emission per unit energy utilization. De-carbonization rates needed to compensate for the growing demand while keeping the CO2-emissions constant should at least be 2% per year compared to actual values of 0.3%. The potential of different de-carbonization rate measures is analyzed. It is argued that the goal can only be met if per capita energy utilization in the industrialized countries is significantly reduced from their typical level of 5000–10 000 W. As a realistic target we suggest 2000 Watt per capita, the present global average. This would leave expansion capacity for the developing countries which presently have per capita demand between 300 and 1000 W. Based on the example of Switzerland it is shown that the two key issues to attain this goal are the quality of buildings and the demand for mobility. It is concluded that the conversion of the present energy system into a 2000 W system is neither limited by technology nor by finances but by the acceptance of a new life style in which energy is used more efficiently and more intelligently than today
