With the demise of the North Atlantic groundfish stocks, the lobster industry has become the most important fishery in New England with Maine’s lobster fishery one of the most successful in the United States. Since 1985, income from lobsters in Maine has steadily increased by nearly 400%. While many view this as a success, this lucrative monoculture puts pressure on the industry with many unknowns in the future ecologically and socially.
Ecosystem-based approaches for climate change adaptation are promoted at international, national, and local levels by both scholars and practitioners. However, local planning practices that support these approaches are scattered, and measures are neither systematically implemented nor comprehensively reviewed. Against this background, this paper advances the operationalization of ecosystem-based adaptation by improving our knowledge of how ecosystem-based approaches can be considered in local planning (operational governance level).
Learn about climate adaptation activities in the Southeast United States, focusing on water resources in 11 states in the Southeast including- Alabama, Louisiana, Georgia, Mississippi, Tennessee, Kentucky, South Carolina, North Carolina, Virginia, Arkansas, and Florida - as well as Puerto Rico and the U.S. Virgin Islands.
Climate change is already changing ecosystems and affecting people in the southwestern United States. Rising temperatures have contributed to large-scale ecological impacts, affecting plants, animals, as well as ecosystem services, e.g., water supply. The climate of the Gunnison Basin, Colorado, is projected to get warmer over the next few decades as part of a larger pattern of warming in the western United States.
A recent NOAA study found that by 2040, Alaskan shellfish hatcheries may no longer be sustainable because of ocean acidification, unless serious mitigation efforts are put in place. We recently reported on a hatchery in Oregon that’s become a model for adapting to these different conditions. But the long term solution may actually lie in shellfish genes. Evolution and resiliency are the buzzwords for a sustainable mariculture industry in Alaska, a state that is particularly vulnerable.
Around the world, the human-induced collapses of populations and species have triggered a sixth mass extinction crisis, with rare species often being the first to disappear. Although the role of species diversity in the maintenance of ecosystem processes has been widely investigated, the role of rare species remains controversial. A critical issue is whether common species insure against the loss of functions supported by rare species.
In California much work is being done at the local and state levels to mitigate the effects of climate change, and develop adaptation strategies. In particular, California recently released for public comment “Safeguarding California: Reducing Climate Risk” – an update to the 2009 California Climate Adaptation Assessment. In it, decision makers specifically highlight the need to improve understanding of climate risks to biodiversity and habitat, among other recommendations.
Climate change can impact the pattern of marine biodiversity through changes in species’ distributions. However, global studies on climate change impacts on ocean biodiversity have not been performed so far. Our paper aims to investigate the global patterns of such impacts by projecting the distributional ranges of a sample of 1066 exploited marine fish and invertebrates for 2050 using a newly developed dynamic bioclimate envelope model. Our projections show that climate change may lead to numerous local extinction in the sub-polar regions, the tropics and semi-enclosed seas.
With rising temperatures and seas, massive droughts, and changing landscapes, successfully adapting to climate change is increasingly important. For humans, this can mean using technology to find solutions. But for some plants and animals, adapting to these changes involves the most ancient solution of all: evolution. Erin Eastwood explains how animals are adapting to climate change.
Climate change adaptation is a rapidly evolving field in conservation biology and includes a range of strategies from resisting to actively directing change on the landscape. The term ‘climate change resilience,’ frequently used to characterize adaptation strategies, deserves closer scrutiny because it is ambiguous, often misunderstood, and difficult to apply consistently across disciplines and spatial and temporal scales to support conservation efforts.
