Hawaiian Islands Climate Vulnerability and Adaptation Synthesis

The goal of the Hawaiian Islands Climate Synthesis Project was to develop comprehensive, science-based syntheses of current and projected future climate change impacts on, and adaptation options for, terrestrial and freshwater resources within the main Hawaiian Islands. The Hawaiian Islands Climate Vulnerability and Adaptation Synthesis presents the results of the major project components - climate impacts assessment, vulnerability assessment, and adaptation planning - and provides an inter-island analysis of the findings. More detailed information is available in the individual vulnerability assessment syntheses and adaptation summaries, and should be referred to for decision support, which can be found at http://bit.ly/HawaiiClimate.

A Three-Step Decision Support Framework for Climate Adaptation: Selecting Climate-Informed Conservation Goals and Strategies for Native Salmonids in the Northern U.S. Rockies

The impact of climate change on cold-water ecosystems—and the cold-adapted native salmonids present in these systems—is the subject of a substantial body of research.. Recently, scientists have developed a number of datasets and analyses that provide insight into projections of climate change e ects on native salmonid populations in the northern U.S. Rockies region. Alongside this research, a number of management options for helping native salmonids respond to the e ects of climate change—also known as ‘climate adaptation’ strategies and actions—have been identi ed by scientists and managers in the region. These analyses and climate adaptation options o er valuable information to managers charged with making di cult decisions about where and how to best conserve and restore the region’s native salmonids given the challenges posed by shifting climatic conditions. Yet managers in the region continue to identify challenges in applying available information on climate change impacts, particularly in determining forward-looking conservation goals and selecting appropriate actions from the long menu of available climate adaptation options.

 

To augment this research and compilation of climate-informed management options, we have developed a decision support framework aimed at helping managers think critically about how to apply climate information to their management decisions. Speci cally, our framework is meant to help managers:

1) articulate an appropriate conservation goal for cold-adapted native salmonid populations taking into account the impacts of climate change on habitat suitability, threats from non-native sh, and connectivity;

2) consider the climate adaptation strategies that might best support that goal; and

3) identify actions that are available to implement the chosen strategies.

Given the complexity and uncertainty of conserving cold-adapted species in an era of rapid climate change and the limited resources available for conservation, choices about where to invest conservation dollars require defensible and transparent decision making. The three-step decision framework we provide here is meant to be a starting point to help managers document how they have incorporated information on climate change into their management decisions and prioritization of limited resources. The process used to develop the framework for native salmonids can be used to tailor decision support for additional conservation targets of interest. Ultimately, managers can integrate this climate change thinking into existing conservation strategies and management plans, alongside the myriad other regulatory, social, economic and locally-driven factors and mandates that in uence management decisions.

Guidelines for incorporating fish distribution shifts into a fisheries management context

The impacts of climate change have been demonstrated to influence fisheries resources. One way climate has affected fish stocks is via persistent shifts in spatio-temporal distribution. Although examples of climate-forced distribution shifts abound, it is unclear how these shifts are practically accounted for in the management of fish stocks. In particular, how can we take into account shifting stock distribution in the context of stock assessments and their management outputs? Here, we discuss examples of the types of fish stock distribution shifts that can occur. We then propose a decision tree framework of how shifting stock distributions can be addressed. Generally, the approaches for addressing such shifts fall into one of three main alternatives: re-evaluate stock identification, re-evaluate a stock unit area, or implement spatially explicit modelling. We conclude by asserting that the approach recommended here is feasible with existing information and as such fisheries managers should be able to begin addressing the role of changes in stock distribution in these fish stocks. The implications of not doing so could be notably undesirable.

The Salt Marsh Advancement Zone Assessment for Connecticut report is the culmination of a statewide study of each of the 24 coastal municipalities in Connecticut. At the municipal scale, these 24 individual reports inform communities about future marsh advancement locations, current land use of those affected properties, and which parcels are critical to the persistence of the community’s salt marshes.

Climate Change Adaptation Manual - Evidence to Support Nature Conservation in a Changing Climate

The need for climate change adaptation has become increasingly widely recognised in the last 20 years. Nature conservation was one of the first sectors to identify the need and to start developing approaches. To date, much of the focus has been on identifying general principles. This was an essential first step, but adaptation needs to be embedded into decision-making in specific places and circumstances. There can be a big gap between general principles and specific applications. Effective adaptation requires local knowledge and experience, combined with relevant scientific information and an understanding of practical options. It will be assisted by sharing good practice and evidence of what techniques have worked in particular places and situations.

This Adaptation Manual is a resource to support practical and pragmatic decision-making, by bringing together recent science, experience and case studies, and is intended to be an accessible entry point to a range of available resources and tools. It is not intended to be read from cover to cover. Different elements stand alone and can be read individually. We anticipate that the information contained here will be useful to a variety of people, including managers of nature reserves and other protected sites, conservation and land management advisors, and environmental consultants. The intended audience is those who are involved in the management of land for conservation and amenity, and includes staff of local and national government, statutory agencies and NGOs.

Much of the work to date on adaptation in the natural environment has been centred on biodiversity, which is the focus for this first edition of the manual, particularly habitat management. However, this is a fast moving field and we anticipate the manual will be a resource that develops and grows over time. Subsequent revisions are intended to deal more thoroughly with species, and how managing the natural environment can help society to adapt to climate change. Other future topics include landscape character, geodiversity, and recreation. We encourage feedback and comment. The manual is designed to support practical adaptation, and the lessons learnt and experience gained will ideally be fed back as case studies to assist others.

Climate-Smart Conservation: Putting Adaptation Principles into Practice

Climate change already is having significant impacts on the nation’s species and ecosystems, and these effects are projected to increase considerably over time. As a result, climate change is now a primary lens through which conservation and natural resource management must be viewed. How should we prepare for and respond to the impacts of climate change on wildlife and their habitats? What should we be doing differently in light of these climatic shifts, and what actions continue to make sense? Climate-Smart Conservation: Putting Adaptation Principles into Practice offers guidance for designing and carrying out conservation in the face of a rapidly changing climate.

Reducing Climate Risks with Natural Infrastructure

As California considers how to adapt to a changing climate, planners often focus on defensive infrastructure with a negative habitat impact: bigger levees, rock walls to protect coastlines or even giant sea gates.

But California can follow a different path. With natural or “green” infrastructure that leverages natural processes to reduce risk to human lives, property and businesses, the state can build resilience to the coming changes while restoring natural habitats instead of degrading them.

“Green” or “natural” infrastructure can include a range of strategies. Some projects focus on preserving existing natural systems, while others are highly engineered, combining green techniques with more traditional “gray” approaches.

This report evaluates nine green infrastructure case studies in California. Each improves flood or coastal protection, provides habitat and preserves or restores the natural dynamics between water and land. We review the available data on the costs and benefits of each case and, where possible, compare this information with the costs and benefits of a gray alternative at the same site.

Climate Change Impacts in the United States: The Third National Climate Assessment

The National Climate Assessment assesses the science of climate change and its impacts across the United States, now and throughout this century. It documents climate change related impacts and responses for various sectors and regions, with the goal of better informing public and private decision-making at all levels.

A team of more than 300 experts, guided by a 60-member National Climate Assessment and Development Advisory Committee produced the full report – the largest and most diverse team to produce a U.S. climate assessment. Stakeholders involved in the development of the assessment included decision-makers from the public and private sectors, resource and environmental managers, researchers, representatives from businesses and non-governmental organizations, and the general public. More than 70 workshops and listening sessions were held, and thousands of public and expert comments on the draft report provided additional input to the process.

The assessment draws from a large body of scientific peer-reviewed research, technical input reports, and other publicly available sources; all sources meet the standards of the Information Quality Act. The report was extensively reviewed by the public and experts, including a panel of the National Academy of Sciences, the 13 Federal agencies of the U.S. Global Change Research Program, and the Federal Committee on Environment, Natural Resources, and Sustainability.

Ecosystem Adaptation to Climate Change in California: Nine Guiding Principles

The goal of this project is to develop a set of scientifically sound, pragmatic, and broadly supported Guiding Principles to help ensure that conservation investments and management choices yield durable benefits in the face of climate change.

The Guiding Principles presented here were developed through a process that combined working with an Expert Panel of leading scientists; consulting with leaders and experts in state government, conservation organizations, and the scientific community; and iterative review of draft documents by technical experts and potential users of the principles.

The focus of this effort is on land-based, freshwater, and tidal systems. Although some principles may be relevant, the panel did not consider marine systems in developing the Guiding Principles.
