Manual de Restauración de Dunas costeras

Las dunas costeras son ecosistemas terrestres únicos situados en la transición entre ambientes continentales y marinos. Como el resto de hábitats costeros, los sistemas dunares son extremadamente frágiles, ajustados en su formación, desarrollo y evolución a procesos naturales, y fácilmente vulnerables frente a la acción humana. Se distribuyen a nivel mundial en todo tipo de climas y en España presentan una amplia distribución tanto en la península como en las islas.

El objetivo de este Manual es dotar de la información que permita proponer las medidas técnicas necesarias para conseguir una restauración ecológica de las dunas costeras, mediante un proceso que facilite la recuperación del ecosistema degradado, dañado o destruido, cuya meta sea recuperar sus valores intrínsecos, elementos bióticos, abióticos y su funcionamiento y dinámica, en su contexto histórico y regional, y que permita la realización de prácticas culturales sostenibles (SER 2002). El Manual va dirigido, por tanto, a los técnicos y gestores que dedican su actividad a la gestión y restauración de los sistemas dunares.

Coastal California Adaptation Policy Briefs

The Stanford Center for Ocean Solutions collaborated with the Natural Capital Project and Stanford Law School to foster a transition from adaptation planning to implementation. Our team engaged planners, managers and others at the city, county and state levels to identify policy and decision-making gaps in the coastal adaptation context. We specifically targeted local communities currently updating their planning documents, such as Local Coastal Programs. This evolved into an investigation of a wide range of legal, nancial and engineered strategies, including legal considerations, potential tradeoffs, and key examples of these strategies when possible.

This compilation of coastal adaptation policy briefs on topics we co-identified with local communities throughout California reflects our research on these topics. Our work aims to provide clarity and information regarding the implementation of particularly salient adaptation strategies and topics. While these compiled resources were developed with a particular focus on local decisionmaking in California, the information can inform similar adaptation work elsewhere.

 

California’s Fourth Climate Change Assessment

California’s Fourth Climate Change Assessment (Fourth Assessment) advances actionable science that serves the growing needs of state and local-level decision-makers from a variety of sectors. This cutting-edge research initiative is comprised of a wide-ranging body of technical reports, including rigorous, comprehensive climate change scenarios at a scale suitable for illuminating regional vulnerabilities and localized adaptation strategies in California; datasets and tools that improve integration of observed and projected knowledge about climate change into decisionmaking; and recommendations and information to directly inform vulnerability assessments and adaptation strategies for California’s energy sector, water resources and management, oceans and coasts, forests, wildfires, agriculture, biodiversity and habitat, and public health. In addition, these technical reports have been distilled into summary reports and a brochure, allowing the public and decision-makers to easily access relevant findings from the Fourth Assessment.

Underwater: Rising Seas, Chronic Floods, and the Implications for US Coastal Real Estate

Along nearly 13,000 miles of coastline of the contiguous United States, hundreds of thousands of buildings lie in the path of rising seas: schools, hospitals, churches, factories, homes, and businesses. As sea levels rise, persistent high-tide flooding of homes, yards, roads, and business districts will begin to render properties effectively unlivable, and neighborhoods—even whole communities— nancially unattractive and potentially unviable.

Yet property values in most coastal real estate markets do not currently reflect this risk. And most homeowners, communities, and investors are not aware of the nancial losses they may soon face.

This analysis estimates the number of homes and commercial properties throughout the coastal United States that will be put at risk from chronic, disruptive flooding—defined as flooding that occurs 26 times per year or more (Dahl et al. 2017; Spanger-Siegfried et al. 2017)—in the coming decades.

 

Webinar: Rapid Vulnerability Assessment Tool for MPA Managers

This webinar originally aired May 8, 2018.

This North American Rapid Vulnerability Assessment Tool helps marine protected area managers evaluate the implications of climate change for the habitats of their sites. The tool was created as part of a project on climate assessment and adaptation by the Commission for Environmental Cooperation.  It is available in English and Spanish and has three parts (a user guide, a set of blank worksheets, and a booklet containing sample completed worksheets), which used together allow marine protected area managers to conduct a rapid vulnerability assessment and adaptation strategy development process. This webinar will cover: 1) why the tool was created, 2) an overview of the tool (how it works, what it looks like, where to find it), 3) the experience of using the tool, and 4) additional application of the tool. Learn more about the tool here.

Presented by Sara Hutto of Greater Farallones Association and Lara Hansen of EcoAdapt.

Webinar co-sponsored by the NOAA National MPA Center, MPA News, and the EBM Tools Network (co-coordinated by OCTO and NatureServe).

Climate Change Adaptation Governance in British Columbia: Workshop Proceedings

On March 6th, 2018, ACT, SFU and Western University co-hosted a workshop in Vancouver on the topic of climate change adaptation and governance in Canada, with a specific focus on issues relating to the British Columbia (BC) context. Attendees included participants from government, academia, private sector, and non-governmental organizations. Particular attention was given to province-wide strategies for adaptation, risk reduction, and the intersection between them. This workshop was part of a series of events being carried out in tandem with research at Western University.1 This report summarizes the discussion with participants on adaptation framed as a set of actions and governance strategies. 

Climate change adaptation is the process of preparing for actual or projected changes in climate averages and extremes. It relies on interpretations and values pertaining to key questions regarding ways hazards and vulnerability are determined; the nature of acceptable interventions; and the determinants of success. As a result, adaptation is both complex and political in nature. The process of identifying the most effective roles for various actors and the best policy instruments to use to reach certain goals is not only value-laden, but complex and uncertain.

In an attempt to untangle this many-faceted issue within the provincial context, participants were asked to consider the following questions:

  1. Based on your experience and professional insight, what are the necessary components for effective climate change adaptation governance in Canada?

  2. Based on existing successes, what roles and mechanisms are required for effective and collaborative adaptation?

  3. What are the barriers to effective adaptation governance, and what are some potential strategies for overcoming them? 

 

Future Sea Level Rise and the New Jersey Coast: Assessing Potential Impacts and Opportunities

Increasing rates of sea level rise caused by global warming are expected to lead to permanent inundation, episodic flooding, beach erosion and saline intrusion in low-lying coastal areas. Sea level rise is a significant and growing threat to the coastal region of New Jersey, USA and this study presents a comprehensive assessment of the expected impacts. We project future sea level rise based on historical measurements and global scenarios, and apply them to digital elevation models to illustrate the extent to which the New Jersey coast is vulnerable. We estimate that 1 to 3 % of New Jersey’s land area will be affected by inundation and 6.5 to over 9 % by episodic coastal flooding over the next century. We also characterize potential impacts on the socioeconomic and natural systems of the New Jersey coast focusing on Cape May Point for illustrative purposes. We then suggest a range of potential adaptation and mitigation opportunities for managing coastal areas in response to sea level rise. Our findings suggest that where possible a gradual withdrawal of development from some areas of the New Jersey coast may be the optimum management strategy for protecting natural ecosystems.

Monitoring Climate Effects in Temperate Marine Ecosystems

This report has been prepared by EcoAdapt for the MPA Monitoring Enterprise. The MPA Monitoring Enterprise, a program of the California Ocean Science Trust, is tasked with developing and implementing monitoring of California’s emerging statewide MPA network. While climate change is not explicitly incorporated into the goals and objectives of California’s MPAs, future evaluations of MPA performance will occur in the context of a changing climate and associated changing oceanographic environment. Moreover, MPA monitoring in California provides a framework that can be applied to inform the climate change management dialogue. A statewide network of MPAs, in which other anthropogenic stressors are reduced, provides a large-scale, natural laboratory to understand how climate changes manifest in ocean ecosystems. Thus, this presents a timely opportunity to develop and recommend an approach to most efficiently and effectively augment MPA monitoring to provide additional information. This information should aid in the interpretation of MPA monitoring results but also can be designed to inform the management dialogue around potential climate change effects on marine ecosystems and adaptation or mitigation measures.

The Monitoring Enterprise engaged EcoAdapt to develop and recommend an approach to supplement MPA monitoring with climate change monitoring that can track climate change effects 

 

Coastal Land Loss and the Mitigation-Adaptation Dilemma: Between Scylla and Charybdis

Coastal land loss is an inevitable consequence of the confluence of three primary factors: population growth, vanishing wetlands, and rising sea levels. Society may either mitigate coastal land loss by engaging in human engineering projects that create technological solutions or restore natural processes that protect the coastal zone, or it may choose to adapt to coastal land loss by shifting development and other human and economic resources out of areas especially at risk for coastal land loss. This Article first details the primary threats to coastal lands. Next, the Article discusses two primary means of addressing coastal land loss— mitigation and adaptation—applying those terms slightly differently than they are used in the broader climate change context in order to focus more precisely on the coastal land loss phenomena and its solutions. Finally, the Article makes three normative claims for why policy-makers should approach coastal land loss mitigation in particular with caution: (1) uncertainty of mitigation’s effectiveness scientifically and institutionally; (2) the political expediency of choosing mitigation over adaptation; and (3) the fact that failure to adapt past land-use activities in the coastal zone has contributed to the need to adapt or mitigate today.
