To help stakeholders such as planners, resource managers, policymakers, and decision makers address environmental challenges in the Anthropocene, scientists are increasingly creating actionable science—science that is useful, usable, and used. Critical physical geography encourages the engagement of stakeholders in the creation of scientific knowledge to conduct actionable science and produce outputs that are directly relevant to stakeholder plans, decisions, or actions. Many scientists, however, lack formal training in how to partner with stakeholders using effective and ethical practices. In this article, we use the core principles for ethical research of respect for persons, beneficence, and justice from the Belmont Report (1979) as a suggested framework to examine the perspectives of stakeholders engaged in climate adaptation science projects. We argue that this framework aligns with the principles of critical physical geography and provides guidance for scientists to make their research more actionable while placing necessary emphasis on ethical considerations. We also challenge scientists to consider the broader ethical implications of engaging with these partners. [ABSTRACT FROM AUTHOR]

Scientists, resource managers, and decision makers increasingly use knowledge coproduction to guide the stewardship of future landscapes under climate change. This process was applied in the California Central Valley (USA) to solve complex conservation problems, where managed wetlands and croplands are flooded between fall and spring to support some of the largest concentrations of shorebirds and waterfowl in the world. We coproduced scenario narratives, spatially explicit flooded waterbird habitat models, data products, and new knowledge about climate adaptation potential. We documented our coproduction process, and using the coproduced models, we determined when and where management actions make a difference and when climate overrides these actions. The outcomes of this process provide lessons learned on how to cocreate usable information and how to increase climate adaptive capacity in a highly managed landscape. Actions to restore wetlands and prioritize their water supply created habitat outcomes resilient to climate change impacts particularly in March, when habitat was most limited; land protection combined with management can increase the ecosystem's resilience to climate change; and uptake and use of this information was influenced by the roles of different stakeholders, rapidly changing water policies, discrepancies in decision‐making time frames, and immediate crises of extreme drought. Although a broad stakeholder group contributed knowledge to scenario narratives and model development, to coproduce usable information, data products were tailored to a small set of decision contexts, leading to fewer stakeholder participants over time. A boundary organization convened stakeholders across a large landscape, and early adopters helped build legitimacy. Yet, broadscale use of climate adaptation knowledge depends on state and local policies, engagement with decision makers that have legislative and budgetary authority, and the capacity to fit data products to specific decision needs.

Although management, and financial resources allocated to management, may facilitate species distribution shifts by reducing anthropogenic pressures, species-specific management may also increase species persistence by maintaining preexisting habitat conditions despite climate warming or by mitigating the negative impacts of the temperature changes (Greenwood et al., 2016). Waterbird communities adjust to climate warming according to conservation policy and species protection status. [Extracted from the article]

FISHERIES , *WILDLIFE conservation , *CLIMATE change , *RAINBOW trout , *HABITAT conservation , *LAKE trout - Abstract
A central tenet of landscape ecology is that mobile species depend on complementary habitats, which are insufficient in isolation, but combine to support animals through the full annual cycle. However, incorporating the dynamic needs of mobile species into conservation strategies remains a challenge, particularly in the context of climate adaptation planning. For cold‐water fishes, it is widely assumed that maximum temperatures are limiting and that summer data alone can predict refugia and population persistence. We tested these assumptions in populations of redband rainbow trout (Oncorhynchus mykiss newberrii) in an arid basin, where the dominance of hot, hyperproductive water in summer emulates threats of climate change predicted for cold‐water fish in other basins. We used telemetry to reveal seasonal patterns of movement and habitat use. Then, we compared contributions of hot and cool water to growth with empirical indicators of diet and condition (gut contents, weight–length ratios, electric phase angle, and stable isotope signatures) and a bioenergetics model. During summer, trout occurred only in cool tributaries or springs (<20 °C) and avoided Upper Klamath Lake (>25 °C). During spring and fall, ≥65% of trout migrated to the lake (5–50 km) to forage. Spring and fall growth (mean [SD] 0.58% per day [0.80%] and 0.34 per day [0.55%], respectively) compensated for a net loss of energy in cool summer refuges (–0.56% per day [0.55%]). In winter, ≥90% of trout returned to tributaries (25–150 km) to spawn. Thus, although perennially cool tributaries supported thermal refuge and spawning, foraging opportunities in the seasonally hot lake ultimately fueled these behaviors. Current approaches to climate adaptation would prioritize the tributaries for conservation but would devalue critical foraging habitat because the lake is unsuitable and unoccupied during summer. Our results empirically demonstrate that warm water can fuel cold‐water fisheries and challenge the common practice of identifying refugia based only on summer conditions. Article impact statement: Warm downstream habitats may be critical for cold‐water fisheries but are overlooked by climate adaptation planning. [ABSTRACT FROM AUTHOR]

CLIMATE change , *EMIGRATION & immigration , *COCOA , *HAZARDS - Abstract
Displacement due to environmental hazards such as sea-level rise and extreme weather has long been a prominent theme of climate adaptation and migration research. Although the relationship between climate adaptation and displacement is typically associated with the involuntary relocation of human bodies and livelihoods, in this article I offer an alternative perspective. Through an examination of recent trends in the Indonesian cocoa sector, I argue that fixing labor and capital in place—often in the form of smallholder producers—has emerged as a core strategy for corporate entities to manage the threat of their own economic displacement. Although this strategy enables corporate entities to maintain cocoa production in the face of economic and environmental disruption, the associated loss of smallholder mobility, constrained livelihood options, and new forms of financial dependency increase smallholder vulnerability to economic and environmental impacts associated with climate change. This work highlights emerging tensions between climate adaptation, displacement, and agrarian change while raising new questions concerning who and what is displaced and how in the context of climate adaptation in the Global South.

ADAPTIVE natural resource management , *CLIMATE change , *ENDANGERED species , *BIOLOGICAL extinction - Abstract
Adaptive capacity (AC)—the ability of a species to cope with or accommodate climate change—is a critical determinant of species vulnerability. Using information on species' AC in conservation planning is key to ensuring successful outcomes. We identified connections between a list of species' attributes (e.g., traits, population metrics, and behaviors) that were recently proposed for assessing species' AC and management actions that may enhance AC for species at risk of extinction. Management actions were identified based on evidence from the literature, a review of actions used in other climate adaptation guidance, and our collective experience in diverse fields of global‐change ecology and climate adaptation. Selected management actions support the general AC pathways of persist in place or shift in space, in response to contemporary climate change. Some actions, such as genetic manipulations, can be used to directly alter the ability of species to cope with climate change, whereas other actions can indirectly enhance AC by addressing ecological or anthropogenic constraints on the expression of a species' innate abilities to adapt. Ours is the first synthesis of potential management actions directly linked to AC. Focusing on AC attributes helps improve understanding of how and why aspects of climate are affecting organisms, as well as the mechanisms by which management interventions affect a species' AC and climate change vulnerability. Adaptive‐capacity‐informed climate adaptation is needed to build connections among the causes of vulnerability, AC, and proposed management actions that can facilitate AC and reduce vulnerability in support of evolving conservation paradigms. Article impact statement: Conservation‐management actions are linked to the realized adaptive capacity of species amidst climate variability and change. [ABSTRACT FROM AUTHOR]

How do polycentric governance systems respond to the emergence of new collective‐action problems? We study this question in the context of the evolution of polycentric systems of sea‐level rise adaptation in the San Francisco Bay Area. We focus on how the structure of polycentric systems changes over time to support cooperation and learning and whether those changes represent a process of centralization or decentralization. The ecology of games framework provides the theoretical background for developing hypotheses about the structure of the system over time. We test the hypotheses by analyzing the polycentric system as a two‐mode network where actors are linked to policy, divided into five time periods from 1991 to 2016. The results suggest that the polycentric system for sea‐level rise adaptation started with a centralized set of actors, which evolved over time to a more decentralized structure. The research has general implications with respect to how polycentric systems manage the trade‐off between maintaining local autonomy and coordinating decisions at the regional level across fragmented policy communities.

DATA management , *ANTHROPOCENE Epoch , *ENVIRONMENTAL databases , *ENVIRONMENTAL monitoring , *APPLIED ecology - Abstract
The Anthropocene affects how we manage the environment in many ways, perhaps most importantly by undermining how past conditions act as baselines for future expectations. In a period when historical analogues become less meaningful, we need to forge new practices and methods of environmental monitoring and management, including how to categorize, manage, and analyze the deluge of environmental data. In particular, we need practices to detect emerging hazards, changing baselines, and amplified risk. Some current data practices, however, especially the designation and dismissal of outliers, might mislead efforts to better adapt to new environmental conditions. In this article we ask these questions: What are the politics of determining what counts as "abnormal" and is worthy of exclusion in an era of the ever-changing "normal"? What do data exclusions, often in the form of outliers, do to our ability to understand and regulate in the Anthropocene? We identify a recursive process of distortion at play where constructing categories of abnormal–normal allows for the exclusion of "outliers" from data sets, which ultimately produces a false rarity and hides environmental changes. To illustrate this, we draw on a handful of examples in regulatory science and management, including the Exceptional Event Rule of the Clean Air Act, beach erosion models for nourishment projects, and the undetected ozone hole. We conclude with a call for attention to the construction of "normal" and "abnormal" events, systems, data, and natures in the Anthropocene. [ABSTRACT FROM AUTHOR]

CLIMATE change , *CLIMATE change mitigation , *BIODIVERSITY conservation , *GOAL (Psychology) , *BIOLOGICAL extinction - Abstract
Expansion of the global protected‐area network has been proposed as a strategy to address threats from accelerating climate change and species extinction. A key step in increasing the effectiveness of such expansion is understanding how novel threats to biodiversity from climate change alter concepts such as rewilding, which have underpinned many proposals for large interconnected reserves. We reviewed potential challenges that climate change poses to rewilding and found that the conservation value of large protected areas persists under climate change. Nevertheless, more attention should be given to protection of microrefugia, macrorefugia, complete environmental gradients, and areas that connect current and future suitable climates and to maintaining ecosystem processes and stabilizing feedbacks via conservation strategies that are resilient to uncertainty regarding climate trends. Because a major element of the threat from climate change stems from its novel geographic patterns, we examined, as an example, the implications for climate‐adaptation planning of latitudinal, longitudinal (continental to maritime), and elevational gradients in climate‐change exposure across the Yellowstone‐to‐Yukon region, the locus of an iconic conservation proposal initially designed to conserve wide‐ranging carnivore species. In addition to a continued emphasis on conserving intact landscapes, restoration of degraded low‐elevation areas within the region is needed to capture sites important for landscape‐level climate resilience. Extreme climate exposure projected for boreal North America suggests the need for ambitious goals for expansion of the protected‐area network there to include refugia created by topography and ecological features, such as peatlands, whose conservation can also reduce emissions from carbon stored in soil. Qualitative understanding of underlying reserve design rules and the geography of climate‐change exposure can strengthen the outcomes of inclusive regional planning processes that identify specific sites for protection. Article Impact Statement: Rewilding concepts updated to consider climate change increase mitigation and biodiversity conservation gain from protected area expansion. [ABSTRACT FROM AUTHOR]

This article brings reflections on the concept of healthy cities in view of the repertoire found in the urban environment of northeastern Brazil. In order to assess the conformity of spaces with what is expected from a healthy city, according to guidelines of the World Health Organization (WHO), a photographic survey was conducted in the municipalities of Petrolina (PE), Arapiraca (AL) and Maceió (AL). With the help of literature, a comparative analysis of the photographs generated was performed. It was observed that the current development model of the cities studied is composed of coherent practices and also practices that are different from what was expected for the construction of a healthy city. Thus, it was noted that the mismatch that exists between healthy and hostile spaces generates discontinuity and stratification in the urban space and in the society that inhabits it. It was also possible to perceive the tendency of the urban buildings to move away from urban healthy practices, a reality that highlights the importance of social paradigms and urban planning aimed at environmental awareness. El presente artículo reflexiona sobre el concepto de ciudades saludables frente al repertorio encontrado en el ambiente urbano del Noreste Brasileño. Con el fin de evaluar la conformidad del espacio urbano construido y lo esperado de una ciudad saludable, según lo postulado por la Organización Mundial de la Salud (OMS), se realizó un levantamiento fotográfico en los municipios de Petrolina (PE), Arapiraca (AL) y Maceió (AL), y, con apoyo en la literatura se realizó un análisis comparativo de las fotografías generadas. Se observó que el modelo de desarrollo actual de las ciudades estudiadas está compuesto por prácticas coherentes y otras disonantes a lo esperado para una ciudad saludable. Asimismo, fue posible notar que la discontinuidad que genera el encuentro entre los espacios saludables y los espacios hostiles origina estratificación en el espacio urbano y en la sociedad que los habita. Finalmente se percibió la tendencia, principalmente en edificaciones recientes a mostrar indiferencia hacia prácticas urbanamente saludables. Esta realidad evidencia la importancia de agilizar el enfoque en los paradigmas sociales y la planificación urbana sobre la consciencia ambiental.

Protected area networks facilitate community changes in responses to climate warming. However, the contribution of the site environmental and conservation-oriented characteristics to these responses to climate warming are not well understood. Here, we investigate how composition of non-breeding waterbird communities within the European Union Natura 2000 (N2K) network changes in response to increases in temperature. We measured the community reshuffling of 97 waterbird species in 3,018 N2K sites over 25 years in 26 European countries. We find that N2K sites explicitly designated for protection of waterbirds and with a management plan had faster climate-driven community changes. In contrast, the designation period of the N2K sites was not associated with community adjustment, and sites funded under EU-LIFE had lower climate-driven community changes. Our findings imply that efficient conservation policy that may help waterbird community responses to climate warming is to manage sites that are specifically designated for waterbirds. Climate warming is driving changes in species distributions and community composition. Many species have a so-called climatic debt, that is, shifts in range lag behind shifts in temperature isoclines. Inside protected areas (PAs), community changes in response to climate warming can be facilitated by greater colonization rates by warm-dwelling species, but also mitigated by lowering extirpation rates of cold-dwelling species. An evaluation of the relative importance of colonization-extirpation processes is important to inform conservation strategies that aim for both climate debt reduction and species conservation. We assessed the colonization-extirpation dynamics involved in community changes in response to climate inside and outside PAs. To do so, we used 25 years of occurrence data of nonbreeding waterbirds in the western Palearctic (97 species, 7071 sites, 39 countries, 1993–2017). We used a community temperature index (CTI) framework based on species thermal affinities to investigate species turnover induced by temperature increase. We determined whether thermal community adjustment was associated with colonization by warm-dwelling species or extirpation of cold-dwelling species by modeling change in standard deviation of the CTI (CTISD). Using linear mixed-effects models, we investigated whether communities in PAs had lower climatic debt and different patterns of community change than communities outside PAs. For CTI and CTISD combined, communities inside PAs had more species, higher colonization, lower extirpation, and lower climatic debt (16%) than communities outside PAs. Thus, our results suggest that PAs facilitate 2 independent processes that shape community dynamics and maintain biodiversity. The community adjustment was, however, not sufficiently fast to keep pace with the large temperature increases in the central and northeastern western Palearctic. Our results underline the potential of combining CTI and CTISD metrics to improve understanding of the colonization-extirpation patterns driven by climate warming.

The growing demand for organic products and the need to plant onions (Allium cepa L.) in the town of Pinhais, Brazil at different times of the year generated this study in the Organic Horticulture Experimental Station of Canguiri-Federal University of Parana, Pinhais, Brazil. The objective was to evaluate the agronomic performance of seven cultivars of open-pollinated onion in an organic system in two planting seasons (January and September) different than traditional times (April and June). The experimental design was completely randomized in a 7x2 factorial scheme with three replicates: Franciscana IPA-10, Vale Ouro IPA-11, Brisa IPA-12, Alfa São Francisco (Cycle VIII), Alfa São Francisco -RT (Thrips tabaci-resistant genotype assessment - Embrapa Semiarid) and BR-29. The results were evaluated for homogeneity by Bartlett’s test and treatment means were compared by Tukey’s test at a significance level of 5%. The variables assessed at the start of bulb formation and harvest were stem height, fresh and dry leaf weight, leaf number and scape diameter. At harvest we measured dry and fresh mass of the bulb, bulb type according to the diameter and productivity. The cultivars Alfa São Francisco and Alfa São Francisco-RT produced higher values of dry mass and productivity in January. La necesidad de abastecer la creciente demanda de productos orgánicos y permitir la plantación de cebolla (Allium cepa L.) en el municipio de Pinhais, Brasil en épocas diferentes a las tradicionales, llevó a realizar un estudio en el Área Experimental de Horticultura Orgánica de la Estación del Canguiri-Universidad Federal de Paraná, municipio de Pinhais, Brasil. El objetivo fue evaluar el desempeño agronómico de siete cultivares de cebolla de polinización abierta, en un sistema orgánico, en dos épocas de siembra (enero y septiembre) diferentes a las épocas tradicionales (abril y junio). El diseño experimental fue completamente al azar, en un esquema factorial 7x2, con tres repeticiones: Franciscana IPA-10 (roja), Vale Ouro IPA-11 y Brisa IPA-12 de la Empresa Pernambucana de Investigación Agropecuaria-IPA, Alfa Tropical de Embrapa Hortalizas, Alfa San Francisco (ciclo VIII), Alfa San Francisco-RT (resistente al Thrips tabaci -genotipo en evaluación- Embrapa Semiárido) y BR-29 de Topseed-Agristar. Los resultados fueron evaluados en cuanto a homogeneidad por el Test de Bartlett y las medias de los tratamientos fueron comparadas por el Test de Tukey al nivel de significancia del 5% de probabilidad.
