Climate Resilience and Sustainability最新文献

This paper reviewed a body of literature on climate adaptation options in sub-Saharan Africa's (SSA) smallholding agriculture and complemented it with a case study involving experts interviews, focus group discussions, large-scale household surveys, and farmer practices observation while drawing insight from the concept of “everyday adaptation and interrupted agency” and agency theory to assess farmer perceived limitations with climate-smart agriculture (CSA) and climate-wise food systems (CWFS) practices for climate adaptation in the SSA. The study noted that the narrow focus on CSA and/or CWFS as a silver bullet for climate change adaptation suitable for smallholding agriculture ignores food producers’ agency to undermine sustainable and inclusive adaptation solutions. Moreover, smallholder farmers’ everyday climate adaptation practices could be grouped into three categories; on-farm adaptation, off-farm adaptation, and Indigenous agroecological adaptation options. The on-farm adaptation options are usually agriculture intensification and extensification. The off-farm adaptation options include livelihood diversification activities, petty trading, seasonal labor jobs, and migration. The Indigenous agroecological adaptation strategy uses observing nature and weather elements to predict the onset of the rainy season. The study noted that smallholders’ adaptation options, which is an expression of their agency, are motivated by smallholders’ desire to be resilient to changing climate, increase productivity and income, and social network influence but not necessarily because the strategy is being promoted by the government or Non-Governmental Organizations (NGOs). Therefore, we propose a sustainable food agency (SFA)—a multifaceted blended constellation of climate adaptation and mitigation strategies, as the best approach to addressing the climate crises in the SSA. The SFA allows individuals or groups to decide what climate change adaptation options best work for them to adapt to changing climate and produce and distribute their food without undermining the economic, social, and environmental bases that generate food security and nutrition for present and future generations.

Climate vulnerability could be influenced by transforming demographic, technological, cultural, political and economic factors, which cuts across global, regional, national and local scales. Such social transformations result in positive and negative outcomes, with implications for the adaptive capacities of resource-poor households, especially those headed by women. However, these transformations are usually not integrated in climate vulnerability assessments. Based on insights from a stakeholders’ brainstorming workshop and the synthesis of information from traditional literature review, this paper contributes to better understanding of the intersections of social transformation with climate vulnerabilities in the Upper West Region of Ghana. The review indicates that the region is experiencing social transformation triggered by technological, demographic and cultural factors, with implications for climate resilience building. For example, compared to the last decade, there is now an increased use of mobile phones, resulting in improved access to e-extension and climate-smart agriculture services. At the same time, an emerging trend of land commodification is driving poor households to sell or lease farming lands. Within the context of these transformations, climate vulnerability is still assessed through approaches that mainly focus on a ‘static’ view of the extent of exposure to climate hazards and their impacts on rural livelihoods. A social transformation analysis that promotes a systematic investigation of the transforming factors is proposed as an effective approach for vulnerability assessment in climate adaptation planning. This approach provides critical reflections on, and sustainable resilience interventions for addressing both changing biophysical and social vulnerabilities of rural communities.

Current discourse relating to climate change, conflict, migration (CCM), and the causal links thereof, is polarized. It is widely acknowledged that climate change will have a detrimental effect on quality of life, and that this impact will not be homogeneous across the globe. However, proposed causal links among CCM remain contentious. This paper argues that to better grasp the implications of climate change on global society and security, it is vital to develop a more systemic understanding of the interplay among CCM. Although this nexus is already recognized, studies to date have tended to be qualitative and statistical evidence of multivariate causality has been lacking, where quantitative analysis is present, it has typically been limited to two components at a time; few studies have addressed the nexus holistically, making research conclusions sometimes difficult to reconcile. Hence, by reviewing literature from a broad range of sources, this paper suggests a suite of systemic and quantitative approaches with which to address the CCM nexus. This review critically assesses the existing research approaches employed across a range of examples and suggests how leveraging the power of ‘big data’ and modelling the nexus as a complex system encapsulating both human and environmental drivers could offer new insights, especially for those looking to explore the increasing number of ‘what if’ scenarios relating to climate and human dynamics.

Greenhouse gas (GHG) emissions have increased globally 10% in the last decade, but there is a large variation in emissions trajectories by country. Understanding the main drivers of recent changes in GHG emissions is important to guide effective climate action. Using a narrative scoping review of academic literature, we access 648 abstracts and review 30 studies to identify statistically significant independent variables that were associated with GHG emissions nationally and multinationally (i.e., in country groupings) during or overlapping the period 2010–2019. We describe the findings in terms of potential reasons for the positive or negative associations, outline the strength of associations relative to other variables within the same study, and compare the associations to findings in other studies. We find that population, energy consumption, and gross domestic product (GDP) per capita are the most common independent variables associated with increases in GHG emissions, whereas the square of GDP per capita and renewable energy production are associated with GHG reductions. We assign GHG drivers to seven categories: economic, energy, demographic, technology innovation, transportation, policy, and others. We conclude by discussing implications for future research and climate policy.

Climate change is causing serious challenges for smallholder farm households, especially in sub-Saharan Africa. The overarching objectives of this study are as follows: (i) to estimate household resilience and vulnerability indices, (ii) identify factors that explain these indices and (iii) to examine the impact of climate-smart agriculture (CSA) on households’ resilience and vulnerability, and (iv) to identify which CSA package performs better in enhancing resilience and reducing vulnerability. For this study, 278 farm households from 4 districts and 8 kebeles from the Central Rift Valley (CRV) of Ethiopia were randomly selected using a three-stage proportional to size sampling procedure. Cross-sectional data applying a structured and pretested survey questionnaire was collected for 2020/21 production season. Household resilience and vulnerability indices were estimated using resilience index and measurement analysis and indicators approaches, respectively. Multinomial endogenous switching regression was used to estimate the average treatment effects (ATEs) of the adoption of CSA practices on households’ resilience and vulnerability. The results show that livestock holding, land size, level of education, and state of food consumption are major explaining factors of resilience, whereas educational level of households, livestock holding, and access to credit are found to be major factors explaining vulnerability. The estimated ATEs indicate that households which adopted more diversified combinations of CSA packages were more resilient and less vulnerable than non-adopter households. The impacts of soil fertility management and conservation agriculture practices have better performance in improving resilience, whereas conservation agriculture and small-scale irrigation performed better in reducing the vulnerability of rural households in CRV. Boosting resilience and reducing vulnerability, hence, requires scaling up CSA among smallholder farmers by diversifying and raising farm households’ income, educational status, and livestock holding.

In this paper, I discuss rhetorical studies’ contribution to the study of environmental communication. With the concept of rhetorical environmental citizenship, I emphasize rhetorical scholarship's concern with citizens’ participation in democracy – both as recipients of and actors in environmental debates. Specifically, this approach invites analyses and evaluations of the public rhetoric of elite actors, considering how it facilitates critical engagement and reflection in matters affecting the environment. Additionally, it encourages examinations of citizens’ democratic participation, attending to how citizens perform, challenge and negotiate their membership in the community also through non-deliberative rhetorical practices.

Increasing climate change risks in Africa, emerging from global warming and their interaction with non-climate risks such as market, have increased the need for comprehensive Climate Risk Management (CRM) that considers both climatic and non-climatic risks and enables actions that address the underlying drivers of vulnerability to these risks. However, comprehensive CRM requires holistic Climate Information Services (CIS), that is, CIS that balances between components focused on provision of short- and long-term climate information for both local and non-local decision makers. In this article, we ask: to what extent is CIS in Africa holistic? We review recent and ongoing CIS interventions in Africa to determine whether a balance of components between short- and long-term CIS for local and non-local decision makers is achieved for holistic CIS. We find a focus on provision of short-term, that is, Sub-Seasonal-to-Seasonal (S2S) CIS for local and non-local decision makers, with limited focus on medium- to long-term (MLT) CIS, particularly MLT CIS for local decision makers which represents the biggest gap to achieving holistic CIS in Africa. We present a supported case that ensuring holistic CIS in Africa will require a portfolio-based approach to CIS development, particularly focusing on MLT CIS for local decision makers. We further highlight the need for integration of this MLT CIS for local decision makers into existing CIS. Achieving this will require: (a) experimentation and innovation with different CIS formats, products and timeframes to enable learning and flexibility to achieve desired goals; (b) capacity development of producers and consumers of climate information to ensure that they have the skills and expertise to understand and generate, and articulate needs and consume MLT CIS respectively; and (c) coordinated allocation of financial resources to ensure that all components of the holistic CIS are advanced.

This article synthesizes critiques of ‘carbon-fix’ strategies in the forestry sector to clarify key concerns about reductionist treatments of forests and carbon and to facilitate further debate. It begins by asserting that since climate change mitigation has been placed at the centre of forest governance, forests have been deemed to serve as ‘carbon-fixing’ devices in ways that can be discerned across three distinct but inter-related categories: (i) carbon storage devices, (ii) carbon removal devices and (iii) net-zero bioenergy devices. A transdisciplinary literature review is used to shed light on key concerns relating to the instrumentalisation of forests within each of these categories. By doing so, this article contributes to a deeper understanding of why relegating forests to a ‘carbon-fix’ function is insufficient to tackle climate change and, rather, poses threats to forest ecosystems and forest-dependent communities. This review ultimately calls into question the use of forests to delay crucial systemic changes, without diminishing the importance of forest conservation, restoration, governance, as well as technological innovation, in mitigating the ongoing harmful effects of climate change.

In agriculture, the possibility of climatic hazards negatively impacting small farmers’ livelihood is high. Thus, there are reasons to contend that climate vulnerabilities could determine economic behaviour. This paper investigates whether discounting behaviour varies with exposure to natural hazards. We analyse data from a survey involving an experiment in which farmers made choices between a smaller immediate payment compared with larger future amounts. The results show that 58% heavily discounted the future in favour of the immediate payment. Among the climatic shocks examined, flood, drought and salinity were the main hazards farmers faced on their plots. However, these natural hazards varied across locations. Our examination of the effect of the experience of natural hazards and the severity of climate vulnerability on farmers’ discounting behaviour suggests that experience and vulnerability had different impacts on discounting behaviour. Recent exposure to drought and flood reduces patience. However, the opposite is the case for a recent experience of salinity. This paper shows that under circumstances of climate vulnerabilities, farmers may be willing to make decisions that result in immediate albeit lower rewards in place of potential higher rewards in the future. The implication is that experience and vulnerability to natural hazards might affect farmers’ decision-making to the extent that it prevents them from a speedy economic recovery post-disaster.

Cultural heritage shapes our identity, delivers capacities, and exposes vulnerabilities, yet cultural heritage value and vulnerability are largely missing from conventional risk assessments. Risk assessments are a fundamental first step in identifying effective mechanisms for Climate Change Adaptation (CCA) and disaster management. However, by ignoring the influence of heritage, decision makers are limiting their understanding of risk and therefore opportunities vital for building and maintaining local resilience. We present findings from a synthesis of peer-reviewed literature from the last 15 years on cultural heritage risk assessment for primarily CCA but with wider implications for disaster management. We identify a significant lack of research examining intangible aspects of heritage and their influence on risk and resilience. Across the literature, risk assessments focus largely on exposure in isolation from vulnerability or adaptive capacity and where vulnerability is included there is no consistent definition or criterion. We highlight that the most frequently used methods have minimal engagement with local community values, experience, and knowledge relating to heritage practice and customs. Community engagement is most often associated with ‘professional experts’ rather than members of a local community. Furthermore, the Global South is severely under-represented with a research bias towards Europe and North America. We recommend an agile approach to future assessments with the adjustment of risk tool research and development to include participatory approaches. Future climate risk frameworks must incorporate community-scale values to understand the role of cultural heritage in relation to adaptive capacity, vulnerability, and resilience.
