Sea-level rise increasingly affects low-lying and exposed coastal communities due to climate change. These communities rely upon the delivery of stormwater and wastewater services which are often co-located underground in coastal areas. Due to sea-level rise and associated compounding climate-related hazards, managing these networks will progressively challenge local governments as climate change advances. Thus, responsible agencies must reconcile maintaining Levels of Service as the impacts of climate change worsen over the coming decades and beyond. A critical question is whether such networks can continue to be adapted/protected over time to retain Levels of Service, or whether eventual retreat may be the only viable adaptation option? If so, at what performance threshold? In this paper, we explore these questions for stormwater and wastewater, using a dynamic adaptive pathway planning (DAPP) approach designed to address thresholds and increasing risk over time. Involving key local stakeholders, we here use DAPP to identify thresholds for stormwater and wastewater services and retreat options, and for developing a comprehensive and area-specific retreat strategy comprising pathway portfolios, retreat phases, potential land use changes, and for exploring pathway conflicts and synergies. The result is a prototype for an area near Wellington, New Zealand, where a managed retreat of water infrastructure is being considered at some future juncture. Dynamic adaptive strategies for managed retreats can help to reduce future disruption from coastal flooding, signal land use changes early, inform maintenance, and allow for gradual budget adjustments by the agencies that can manage expenditure over time. We present this stepwise process in a pathway form that can be communicated spatially and visually, thereby making a retreat a more manageable, sequenced, adaptation option for water agencies, and the communities they serve.

<p>Climate change impacts are beginning to be felt across the world. Therefore, the development and understanding of adaptation options is becoming more important. Sea-level rise and its associated impacts are predicted to continue and accelerate well into the next century. As such, it is important that adaptation options which reduce risks associated with sea-level rise are developed and are well understood. Managed retreat is one such option. While research on managed retreat is increasing, there is a lack of literature that identifies what managed retreat comprises, how to plan and stage the option over time, and how to cost it as an adaptation option.  This thesis aims to address this gap in the literature by answering the following three questions: (1) what are the issues related to implementing managed retreat as an adaptation strategy in coastal areas, now, and moving into the future?; (2) what are the components of managed retreat?; and (3) what framework could be developed for costing managed retreat?  A qualitative ‘desk-top’ approach was taken to deconstruct the components of managed retreat across space and time and to develop a framework for costing the components as part of an adaptation strategy. An in-depth analysis of literature, enabled an understanding of managed retreat implementation, and also informed the development of a component typology and costing framework for the adaptation option. The typology and framework were then tested for relevance and utility for decision making through a series of semi-structured discussions with key informants working in climate change adaptation.  Using the component typology and costing framework, a new approach is presented for staging and costing managed retreat, over time and in different contexts. The typology and framework contribute knowledge and guidance for local governments and infrastructure agencies when discussing managed retreat with their communities, for identifying and staging managed retreat, and for the costing of components. It does this by presenting components in stages as overlapping and parallel pathways, providing groupings of components according to types of costs, and identifying appropriate costing methodologies that enable the implementation of managed retreat. To conclude, the thesis suggests areas for future research on managed retreat.</p>

The Cost

Adaptation gaps arise when observed adaptation to climate change is slower than perceived adaptation potential. Two common explanations for adaptation gaps are (1) private parties failing to recognize that the climate is changing and (2) the cost of adaptation is higher than commonly believed. This paper shows how these two explanations are linked and that the likelihood and duration of adaptation gaps depend on whether climate change is characterized by stationary or non-stationary dynamics. Using an investment in water-saving irrigation in California’s Central Valley as an illustrative example, we find little evidence that failing to account for climate change would explain adaptation gaps. A more likely explanation for adaptation gaps is a failure to account for the adaptation option value that arises due to the possibility of maladaptation.

AbstractThe global climate change has become one of the imperative issue for the smallholder dominated agriculture and tourism sectors in Sri Lanka. This study investigated the perception of farmers on climate change and the potential of agritourism as a sustainable adaptation option to mitigate the negative impacts of climate change in both tourism and agricultural sectors. The study was carried out in the low country dry zone (LCDZ) and the upcountry wet zone (UPWZ) of Sri Lanka. A survey strategy followed by structured and unstructured interviews were undertaken to collect the data. The sample was composed of 100 farmers each from the UPWZ and LCDZ respectively. The study revealed that there had been climate extremes in both climatic zones in terms of high rainfall and longer dry spells. Thus, it was important for the farmers to have necessary knowledge and skills on different diversification techniques related to crop-production, integrated farming systems and climate resilient production which are economical and mitigate the adverse climatic effects. However, the results revealed that the farmers have altered the cropping patterns and crop management practices rather than adopting entrepreneurial activities like agritourism. Lack of awareness of agritourism within the farming community is the main reason for farmers not contemplating this important diversification option. The results indicate that a significant number of farmers showed interest in considering agritourism as an option to mitigate climate change. It is important to educate farmers on diversification options.
