Equitable mitigation to achieve the Paris Agreement goals

Abstract: Five equitable approaches to mitigation are investigated: the authors find that most developing countries are more ambitious than the average, whilst if developed nations and China adopted the average of the approaches the gap between INDCs and a 2 °C pathway would narrow.

Europe's population at a turning point

Abstract: Low birthrates in Europe have begun to generate negative population momentum, a new force for population shrinkage over the coming decades. Birthrates are low partly because of the current trend in Europe toward bearing children at later and later ages. A continuation of this trend could substantially exacerbate future aging of the population and contribute to a future decline in population size. Social policies and labor laws aimed at halting further increases in the mean age of childbearing are proposed in this Policy Forum.

The missing link between flood risk awareness and preparedness: findings from case studies in an Alpine Region

Abstract: The low risk awareness of the residents living in flood-prone areas is usually considered among the main causes of their low preparedness, which in turns generates inadequate response to natural disasters. In this paper, we challenge this assumption by reporting on the results of a sociological research in four communities exposed to flood risk in the Eastern Italian Alps. The research design included semi-structured interviews and focus groups with key local stakeholders and a standardized questionnaire submitted to 400 residents. Results revealed that residents felt both slightly worried about flood risk and slightly prepared to face an event. Considerable differences were found between the evaluations of individual subjects as opposed to overall communities. There was also a clear discrepancy between the actual adoption of household preparatory measures and the willingness to take self-protection actions. Overall, the risk awareness was significantly higher among those residents who had been personally affected by a flood in the past, were living in isolated (vs. urban) communities, in the most risky areas or had a lower level of trust in local authorities. The improvement of residents’ knowledge about their environment and the residual risk seemed to be crucial to increase risk awareness, and the same was true for the strengthening of local support networks to foster preparedness. The link between risk awareness and preparedness was not at all straightforward. Results revealed instead the complexity of residents’ perspectives, attitudes, behaviours and decisions about risk-related issues.

Tools and methods in participatory modeling: Selecting the right tool for the job

Abstract: Various tools and methods are used in participatory modelling, at different stages of the process and for different purposes. The diversity of tools and methods can create challenges for stakeholders and modelers when selecting the ones most appropriate for their projects. We offer a systematic overview, assessment, and categorization of methods to assist modelers and stakeholders with their choices and decisions. Most available literature provides little justification or information on the reasons for the use of particular methods or tools in a given study. In most of the cases, it seems that the prior experience and skills of the modelers had a dominant effect on the selection of the methods used. While we have not found any real evidence of this approach being wrong, we do think that putting more thought into the method selection process and choosing the most appropriate method for the project can produce better results. Based on expert opinion and a survey of modelers engaged in participatory processes, we offer practical guidelines to improve decisions about method selection at different stages of the participatory modeling process.

The Limits of Consensus

Abstract: The establishment of consensus by the IPCC is no longer as critical to governments as a full exploration of uncertainty.
