Framework Convention on Climate Change

Cet article analyse les relations conceptuelles (imprecises) de la vulnerabilite, de la resilience et de la capacite d’adaptation aux changements climatiques selon le systeme socio-ecologique (socio-ecologigal systems – SES) afin de comprendre et anticiper le comportement des composantes sociales et ecologiques du systeme. Une serie de questions est proposee par l’auteur sur la specification de ces termes afin de developper une structure conceptuelle qui inclut les dimensions naturelles et so...

Linkages between vulnerability, resilience, and adaptive capacity

There is growing awareness that ‘nature-based solutions' (NbS) can help to protect us from climate change impacts while slowing further warming, supporting biodiversity and securing ecosystem servi...

Understanding the value and limits of nature-based solutions to climate change and other global challenges

The global response to warming of 1.5oC comprises transitions in land and ecosystem, energy, urban and infrastructure, and industrial systems. The feasibility of mitigation and adaptation options, and the enabling conditions for strengthening and implementing the systemic changes, are assessed in this chapter.

Dredging versus hedging: Comparing hard infrastructure to ecosystem-based adaptation to flooding

Policy-makers view community resilience as fundamental to mitigating loss and damage from climate-related disasters. Although energy has been devoted to defining resilience, less effort has been devoted to analysing the effects of resilience on loss and damage, which is critical in places with limited capacity for adaptation. We use survey data to develop a composite index of community resilience in Fiji and then evaluate the extent to which community resilience mitigates loss and damage. We find that community resilience is negatively correlated with damages over which human intervention may be effective, but not with damages over which intervention is less effective, suggesting that community resilience may limit impacts. We further find that this result holds for a cyclone (about which communities had substantial advance warning) but not for river flooding (for which communities had little advanced warning), suggesting that early warning is necessary for community resilience to become responsive.

Does community resilience mitigate loss and damage from climaterelated disasters? Evidence based on survey data

This paper quantifies the economic impacts of flooding in the Ba River and Penang River catchments in Viti Levu, Fiji. We conducted a detailed assessment of flood damage stemming from two major flooding events in 2012 that severely affected the two important catchments, primarily by using evidence from a novel survey administered in early 2013. We combine these empirical measures of damage with GIS data to estimate total damages from flooding and find that the January 2012 flood caused FJ$36.4 and FJ$12.2 in damages for the Ba River and Penang River catchments, respectively, while the March 2012 flood caused FJ$24.1 and FJ$8.4 in damages for the Ba River and Penang River catchments, respectively. We then estimate the cost of future flooding under moderate and severe climate change projections. Flooding is projected to become more frequent and more severe under both scenarios, with annual losses increasing by 100% with moderate climate change and by 300% with severe climate change. For perspective, damages...

Climate change and the economic impacts of flooding on Fiji

Land policies around the world tend to focus on support for agricultural output. We argue that this leads to ineffective public expenditure, environmental harm and missed opportunities for the use of rural resources. Applying thinking centred on ecosystems services to the governance of rural land would secure greater social value.

Focus rural land policies on ecosystem services, not agriculture.

Climate change costs more than we think because people adapt less than we assume
