The interplay between climate change and disaster risk reduction policy: evidence from Mexico

Mexico gained worldwide reputation for its efforts to develop both climate change (CC) and disaster risk reduction (DRR) policies at the national and international levels. However, the integration of agreements such as the Kyoto Protocol and the Hyogo and Sendai Frameworks into the national institutional setting has been challenging in terms of creating a coherent national risk reduction policy. The purpose of this paper is to analyse the interplay between DRR and CC domains; it provides evidence for the situation in Mexico by comparing the institutions and main actors in both fields as well as the financial and operational instruments currently in force. The comparison is based on institutions’ jurisdictions, priorities and lines of action. This paper synthesises the most important policy instruments, their meeting points and their contradictions and discusses the implications of such policy setting for the implementation of effective CC risk policies. The study depicts a fragmented policy interface with serious shortcomings in terms of the institutional design necessary to coordinate actions. The article concludes that, despite the multiple conceptual and political intersections between both policy fields, the implementation of specific, shared actions would hardly overcome the difficulties imposed by the current, fragmented normative frameworks and jurisdictions.     

Infiltrating citizen-driven initiatives for sustainability

To examine how citizen-driven initiatives for sustainability strive to bring about change and spread their practices, efforts to link social movement, grassroots innovation and green-consumption movements theory are built upon. Göteborg’s citizen-driven waste-prevention initiatives, such as food waste recovery, creating common reuse spaces in housing blocks, exchanging used toys and repairing abandoned bicycles, are considered with data from observations, workshops, documents, social media communications and in-depth interviews. Citizen-driven initiatives succeeded in mobilizing material resources, displaying and reframing various rationales, and creating collaborative local networks to develop their waste-prevention practices. These practices infiltrated the municipal administration, matching incipient institutional mandates to minimize waste. By so doing, they bring within mainstream institutions radical rationales that can become activated in the future, contributing to diachronic change.     

A policymaking perspective on disaster risk reduction in Mozambique

Academics and practitioners alike emphasise that public policy plays a key role to support efforts to reduce disaster risks and to buffer the impacts of natural hazards when they occur. This involves developing public policies to promote disaster risk reduction (DRR). However, the public policy dimension has only recently begun to receive attention in empirical research on DRR. Processes of policy change are discussed, yet less often studied, and more empirical research is needed to advance the understanding of the conditions for DRR policy change. Combining insights from adaptation research and public policy theory, this study investigates the long-term development of DRR policy in Mozambique as perceived by multiple stakeholders. The study identifies barriers and enabling factors influencing the DRR policy process over time. Using data from 37 semi-structured interviews, the study finds six main enabling factors supporting DRR policy change. Among the most important enabling factors are past disasters and broad stakeholder involvement. The study also unveils several barriers to DRR policy change, including resource insufficiency and lack of coordination among stakeholders. The study concludes with suggestions for integrating DRR and policy process research and lessons for policymaking in support of DRR over time.     

The social consequences of a natural/technological disaster: evidence from Louisiana and Mississippi

Disaster scholarship shows that people’s relationships stay the same or improve after natural disasters and become worse after technological, or human-induced, events. Using the case of Katrina, this research explores what happens to people’s relationships after a disaster that began with a catastrophic natural event and was followed by numerous failures in the way human institutions responded to the event. Through an analysis of survey data collected in devastated areas of Louisiana and Mississippi in 2008, this study tests how consequences of both natural (damage to the home and having to leave the home) and technological events (distrust in government, stress, concern about toxic exposure, and pursuing litigation) affect people’s relationships with family members and community groups. Damage to the home, distrust in government, and the pursuit of litigation lead to declines in people’s relationships. These experiences are more likely to change intimate relationships (with family) than relationships in the broader community. The relevance that these findings have for creating better social justice outcomes after future disasters is discussed.
