A metric‐based framework for climate‐smart conservation planning

Ecological Applications, Год журнала: 2023, Номер 33(4)

Опубликована: Март 22, 2023

Abstract Climate change is already having profound effects on biodiversity, but climate adaptation has yet to be fully incorporated into area‐based management tools used conserve such as protected areas. One main obstacle the lack of consensus regarding how impacts can included in spatial conservation plans. We propose a climate‐smart framework that prioritizes protection refugia—areas low exposure and high biodiversity retention—using metrics. explore four aspects planning: (1) model ensembles; (2) multiple emission scenarios; (3) metrics; (4) approaches identifying refugia. illustrate this Western Pacific Ocean, it equally applicable terrestrial systems. found all planning considered affected configuration The choice metrics refugia have large resulting plans, whereas models scenarios smaller effects. As plans depended used, plan based single measure (e.g., warming) will not necessarily robust against other measures ocean acidification). therefore recommend using most relevant for region or drivers. To include uncertainty associated with different futures, we (i.e., an ensemble) scenarios. Finally, show identify feature trade‐offs between: degree which they are climate‐smart, their efficiency meeting targets. Hence, approach depend relative value stakeholders place adaptation. By framework, areas designed improved longevity thus safeguard current future change. hope proposed helps transition toward approaches.

Abstract Few coastal ecosystems remain untouched by direct human activities, and none are unimpacted anthropogenic climate change. These drivers interact with exacerbate each other in complex ways, yielding a mosaic of ecological consequences that range from adaptive responses, such as geographic shifts changes phenology, to severe impacts, mass mortalities, regime loss biodiversity. Identifying the role change these phenomena requires corroborating evidence multiple lines evidence, including laboratory experiments, field observations, numerical models palaeorecords. Yet few studies can confidently quantify magnitude effect attributable solely change, because seldom acts alone ecosystems. Projections future risk further complicated scenario uncertainty – is, our lack knowledge about degree which humanity will mitigate greenhouse-gas emissions, or make ways we impact Irrespective, ocean warming would be impossible reverse before end century, sea levels likely continue rise for centuries elevated millennia. Therefore, risks projected mirror impacts already observed, severity escalating cumulative emissions. Promising avenues progress beyond qualitative assessments include collaborative modelling initiatives, model intercomparison projects, use broader systems. But reduce rapidly reducing emissions greenhouse gases, restoring damaged habitats, regulating non-climate stressors using climate-smart conservation actions, implementing inclusive coastal-zone management approaches, especially those involving nature-based solutions.

3D ocean assessments reveal that fisheries reach deep but marine protection remains shallow

Nature Communications, Год журнала: 2024, Номер 15(1)

Опубликована: Май 21, 2024

The wave of new global conservation targets, the conclusion High Seas Treaty negotiations, and expansion extractive use into deep sea call for a paradigm shift in ocean conservation. current reductionist 2D representation to set targets measure impacts will fail at achieving effective biodiversity Here, we develop framework that overlays depth realms onto marine ecoregions conduct first three-dimensional spatial analysis achievements fisheries footprint. Our novel approach reveals gaps mesophotic, rariphotic, abyssal depths an underrepresentation high protection levels across all depths. In contrast, 3D footprint covers depths, with benthic fishing occurring down lower bathyal mesopelagic peaking areas overlying Additionally, efforts are biased towards where lowest pressures occur, compromising effectiveness network. These mismatches emphasize need thinking achieve sustainability.

Climate velocity drives unexpected southward patterns of species shifts in the Western Mediterranean Sea

Ecological Indicators, Год журнала: 2024, Номер 160, С. 111741 - 111741

Опубликована: Март 1, 2024

The Mediterranean Sea is one of the most vulnerable ecosystems in world due to variety and severity cumulative impacts faced, including high climate risk. Species distributions are expected track niches response warming, with meridionalization (i.e. northern spread native warm-water species) as a common documented response. However, environment also highly heterogeneous structured at regional scales, constraining generalized species responses. Based on long-term monitoring data demersal communities Western (1994–2019), we calculated seven indicators characterizing space–time patterns multiple their temporal rates change. Simultaneously, computed velocity based variation sea surface temperature. Subsequently, modeled velocity, taking into account species' temperature depth preferences. Contrary northward expectation consequence communities' meridionalization, large number have shifted toward south southwest higher medium r values averaged warmer conditions. In general, cold-water an affinity for low moderate mean wide narrow ranges were better tracking velocity. Furthermore, distributed over continental shelf towards shallower inshore waters opposed further away contrary priori expectations shifts deeper waters, following bathymetric gradient. dispersion spatial heterogeneity these expanded, although not explicitly suggesting additional synergistic drivers. Our results confirm importance useful metric predicting responses sub-regional levels provide information scales required embracing local management measures.

Abstract Rapid anthropogenic climate change is driving threatened biodiversity one step closer to extinction. Effects on native are determined by an interplay between species' exposure and their specific ecological life‐history characteristics that render them even more susceptible. Impacts have already been reported, however, a systematic risk evaluation of marine populations lacking. Here, we employ trait‐based approach assess the 90 Mediterranean species change, combining increased sea temperature intrinsic vulnerability. One‐quarter Sea predicted be under elevated levels risk, with various traits identified as key vulnerability traits. High‐risk taxa including turtles, mammals, Anthozoa Chondrichthyes highlighted. Climate hotspots distributed along Western Mediterranean, Alboran, Aegean, Adriatic Seas. At each ecoregion, 21%–31% high risk. All protected areas host 90% having minimum 4 up 19 making objective climate‐smart conservation strategy crucial task for immediate planning action. Our findings aspire offer new insights systematic, spatially strategic prioritization vulnerable life in face accelerating change.

A sustainable blue economy may not be possible in Tanzania without cutting emissions

The Science of The Total Environment, Год журнала: 2024, Номер 947, С. 174623 - 174623

Опубликована: Июль 10, 2024

Balancing blue growth with the conservation of wild species and habitats is a key challenge for global ocean management. This exacerbated in Global South nations, such as Tanzania, where climate-driven change requires delicate marine spatial planning (MSP) trade-offs to ensure climate resilience resources relied upon by coastal communities. Here, we identified challenges opportunities that presents near-term management Tanzania's artisanal fishing sector, protected areas seaweed farming. Specifically, meta-analysis modelling region was carried out estimate natural distribution support these socially important sectors. We estimated changes within next 20 40 years, using projections forced under emissions trajectories, well wealth GIS habitat suitability data derived from globally distributed programmes. Multi-decadal analyses indicated long-term trends extreme weather present activity sectors, locally regionally. Only few instances did identify exhibiting sectoral expansion. Including refugia bright spots effective strategies may serve nature-based solutions: promoting adaptive capacity some most vulnerable economic sectors; creating wage-gaining promote gender parity; delivering benefits thriving possible. Without curbs emissions, however, bleak future emerge valuable biodiversity hosted its communities, despite expansion or other pressures. Growing sustainable economy this part remains substantial without decarbonization.
