<p>The forefront of science now is in bridging fields and making connections across different disciplines, challenging our current understanding of the Earth's changes and overall state. Some of the most challenging science questions now have to do with warnings for significant geohazards and Earth-Space systems' response to climate variability affecting adaptation processes, such as geosphere changes due to climate change and resultant strategies. In recent years, the study of pre-earthquake processes has led for example to developing the lithosphere-atmosphere-ionosphere-coupling concept. This in turn provides new information about the Earth's energy balance (Pulinets and Ouzounov, 2011). From space-born NASA and NOAA Earth observation of atmospheric conditions, we have shown the consistent occurrence of radiative emission anomalies in the atmosphere near or over regions of earthquakes, volcanoes, and geothermal fluxes. Our assessment shows that the latent heat released before major earthquakes is larger than the seismic energy released during the quake (Ouzounov et al., 2018). We find that the associated pre-earthquake phenomena for large events may create an additional thermodynamic contribution in the atmosphere and impact on climate, caused by sources of Earth de-gassing in the lithosphere and followed by ionization processes. Because of these findings, we start exploring major global geodynamics activities and their impact on atmospheric processes and climate through the geosphere coupling channels as a potential forward process of interaction between geohazards and climate adaptation. The reverse mechanism of climate adaptation's impact on geohazards is based on the initial idea that climate adaptation could force additional geohazards activities (McGuire, 2010). The removal of ice sheets may somehow or likely have permitted the release of stresses that had accumulated on previously confined faults, triggering earthquakes in the US, Canada, and Europe. How realistically is it to expect a change in the existing earthquake patterns in Europe, the USA, and Canada during climate change processes? It is plausible, but we do not yet know the answer. Our goal is to explore the coupling between geohazards processes and climate change processes through the lithosphere-atmosphere framework, focusing on dynamic environments, exhibiting a change in physical and thermodynamics processes over relatively small-time scales.</p>

AbstractAs climate change accelerates the frequency and intensity of natural disasters, damage to public and private property is also increasing, putting exorbitant strain on governments and communities. Societies across the world are working to adapt to climate change, but climate adaptation is currently inadequate to meet the needs of the people left increasingly vulnerable and the places that risk being irreversibly changed or destroyed. One tactic of climate adaptation is strategic retreat, sometimes referred to as managed retreat. Strategic retreat is the process by which the government or another entity purchases (buys out) developed properties that are at risk of destruction or have been destroyed by natural disasters. The structure is most often demolished, and the land is placed under a permanent easement to prevent future development. What happens next is dependent on the entities involved in the buyouts, and can range from derelict, vacant lots to full restoration of ecosystems and their abilities to mitigate flood damage. Sometimes recreational amenities, such as trails or park infrastructure, are prioritized and funded as well. Conservation organizations can leverage their expertise in conservation planning, land acquisition and restoration, policy advocacy, and partnership development to improve the implementation of strategic retreat so that nature and people can thrive in the long term. In this policy paper, we review ways that conservation organizations have and can continue to engage in buyout processes to ensure positive outcomes for communities and nature. Conservation organizations must also evolve their approaches to climate adaptation to integrate equity and redress historical injustices in land use, and contribute towards improving strategic retreat for a more just and resilient future across disaster-prone communities. This work focuses on the context of disasters and climate adaptation in the USA, though many of the principles presented are applicable around the world.

AbstractResilience thinking – an approach for understanding and managing change – is increasingly central to climate change adaptation law and policy. Yet the influence of adaptation law and policy on the distribution of climate impacts is often overlooked in studies of socio-ecological resilience to climate change. This article demonstrates how environmental justice scholarship helps to address this gap in the literature relating to adaptation law and resilience. Drawing on existing literature, the article identifies four principles to promote resilience and justice through climate adaptation laws. Climate adaptation laws must (i) prepare for, and respond to, change; (ii) address the distributive effects of climate change and adaptation; (iii) promote participation in adaptation processes; and (iv) cross sectors and scales. Each criterion can be implemented in part through existing legal processes, but might also be further supported by incremental law reform. Developing both resilience and justice dimensions will enhance the effectiveness of adaptation laws in addressing climate impacts.

Current research on climate change adaptation in cities highlights the role of local governments in facilitating adaptation actions, but rarely assesses whether (and if so, how) local communities organise around emerging climate priorities to affect political change. This paper explores changing state–society relationships through the reconstitution of community collectives and advocacy organisations for advancing climate change adaptation in the Indian city of Indore. The paper shows that communities are indeed recognising the need for adaptation but are, at the same time, integrating adaptation actions with existing strategies for advocating development rights. Communities are also rebuilding alliances between municipal and local institutions for public service and infrastructure provision, which point to the centrality of community politics in urban climate adaptation processes. However, such mobilisations are often dependent on existing political networks and a legacy of advocacy around poverty alleviation needs, which sideline more transformative agendas around inclusiveness, equity, and resilient urban futures.

AbstractCities around the world are confronted with the need to put in place climate adaptation policies to protect citizens and properties from climate change impacts. This article applies components of the framework developed by Moser and Ekström (2010) onto empirical qualitative data to diagnose institutional barriers to climate change adaptation in the Municipality of Beirut, Lebanon. Our approach reveals the presence of two vicious cycles influencing each other. In the first cycle, the root cause barrier is major political interference generating competing priorities and poor individual interest in climate change. A second vicious cycle is derived from feedbacks caused by the first and leading to the absence of a dedicated department where sector specific climate risk information is gathered and shared with other departments, limited knowledge and scientific understanding, as well as a distorted framing or vision, where climate change is considered unrelated to other issues and is to be dealt with at higher levels of government. The article also highlights the need to analyze interlinkages between barriers in order to suggest how to overcome them. The most common way to overcome barriers according to interviewees is through national and international support followed by the creation of a data bank. These opportunities could be explored by national and international policy-makers to break the deadlock in Beirut.

Reducing vulnerability to climate change and enhancing the long-term coping capacities of rural or urban settlements to negative climate change impacts have become urgent issues in developing countries. Developing countries do not have the means to cope with climate hazards and their economies are highly dependent on climate-sensitive sectors such as agriculture, water, and coastal zones. Like most countries in Southern Africa, Zimbabwe suffers from climate-induced disasters. Therefore, this study maps critical aspects required for setting up a strong financial foundation for sustainable climate adaptation in Zimbabwe. It discusses the frameworks required for sustainable climate adaptation finance and suggests the direction for success in leveraging global climate financing towards building a low-carbon and climate-resilient Zimbabwe. The study involved a document review and analysis and stakeholder consultation methodological approach. The findings revealed that Zimbabwe has been significantly dependent on global finance mechanisms to mitigate the effects of climate change as its domestic finance mechanisms have not been fully explored. Results revealed the importance of partnership models between the state, individuals, civil society organisations, and agencies. Local financing institutions such as the Infrastructure Development Bank of Zimbabwe (IDBZ) have been set up. This operates a Climate Finance Facility (GFF), providing a domestic financial resource base. A climate change bill is also under formulation through government efforts. However, numerous barriers limit the adoption of adaptation practices, services, and technologies at the scale required. The absence of finance increases the vulnerability of local settlements (rural or urban) to extreme weather events leading to loss of life and property and compromised adaptive capacity. Therefore, the study recommends an adaptation financing framework aligned to different sectoral policies that can leverage diverse opportunities such as blended climate financing. The framework must foster synergies for improved impact and implementation of climate change adaptation initiatives for the country.

AbstractAs the climate evolves over the next century, the interaction of accelerating sea level rise (SLR) and storms, combined with confining development and infrastructure, will place greater stresses on physical, ecological, and human systems along the ocean-land margin. Many of these valued coastal systems could reach “tipping points,” at which hazard exposure substantially increases and threatens the present-day form, function, and viability of communities, infrastructure, and ecosystems. Determining the timing and nature of these tipping points is essential for effective climate adaptation planning. Here we present a multidisciplinary case study from Santa Barbara, California (USA), to identify potential climate change-related tipping points for various coastal systems. This study integrates numerical and statistical models of the climate, ocean water levels, beach and cliff evolution, and two soft sediment ecosystems, sandy beaches and tidal wetlands. We find that tipping points for beaches and wetlands could be reached with just 0.25 m or less of SLR (~ 2050), with > 50% subsequent habitat loss that would degrade overall biodiversity and ecosystem function. In contrast, the largest projected changes in socioeconomic exposure to flooding for five communities in this region are not anticipated until SLR exceeds 0.75 m for daily flooding and 1.5 m for storm-driven flooding (~ 2100 or later). These changes are less acute relative to community totals and do not qualify as tipping points given the adaptive capacity of communities. Nonetheless, the natural and human built systems are interconnected such that the loss of natural system function could negatively impact the quality of life of residents and disrupt the local economy, resulting in indirect socioeconomic impacts long before built infrastructure is directly impacted by flooding.

Although Indigenous peoples’ perspectives and concerns have not always been accommodated in climate change adaptation research and practice, a burgeoning literature is helping to reframe and decolonise climate adaptation in line with Indigenous peoples’ lived experiences. In this review, we bring together climate adaptation, decolonising and intersectional scholarship to chart the progress that has been made in better analysing and responding to climate change in Indigenous contexts. We identify a wealth of literature helping to decolonise climate adaptation scholarship and praxis by attending to colonial and neo-colonial injustices implicated in Indigenous peoples’ climate vulnerability, taking seriously Indigenous peoples’ relational ontologies, and promoting adaptation that draws on Indigenous capacities and aspirations for self-determination and cultural continuity. Despite calls to interrogate heterogenous experiences of climate change within Indigenous communities, the decolonising climate and adaptation scholarship has made limited advances in this area. We examine the small body of research that takes an intersectional approach to climate adaptation and explores how the multiple subjectivities and identities that Indigenous peoples occupy produce unique vulnerabilities, capacities and encounters with adaptation policy. We suggest the field might be expanded by drawing on related studies from Indigenous development, natural resource management, conservation, feminism, health and food sovereignty. Greater engagement with intersectionality works to drive innovation in decolonising climate adaptation scholarship and practice. It can mitigate the risk of maladaptation, avoid entrenchment of inequitable power dynamics, and ensures that even the most marginal groups within Indigenous communities benefit from adaptation policies and programmes.
