Purpose This paper aims to increase the resilience of building systems, especially roofs, in relation to climate changes. The focus is on Mediterranean cities, where, often, there is no regulation about these issues. Therefore, it is necessary to define resilience indicators through comparative studies of adaptive roof solutions to mitigate overheating in summer. Design/methodology/approach Through software simulations and data comparison, a specific methodological approach is used to analyze the resilience levels of different roof solutions (phase change materials, aerogel, green and cool roof), starting from energy efficiency as a prerequisite of resilience. Moreover, a case study of a historic existing building in a southern Italian town is examined. Findings The findings show the best strategies for building systems, especially for roofs, to decrease urban heat island effects according to the defined resilience indicators against overheating mitigation. Research limitations/implications Other building systems, such as facades, also have to be investigated in relation to climate change mitigation. Practical implications The implementation of resilient solutions that can also affect neighborhood for urban heat island mitigation. Social implications Because of resilience indicators definition, it is easier to introduce economic incentives according to reference thresholds and to increase community involvement. Originality/value The paper provides a new approach for the evaluation of technological solutions for a building from a resilience point of view, which has energy efficiency as pre-condition.

Purpose – In order to achieve reductions in greenhouse gas (GHG) emissions, it is essential that all industry sectors have the appropriate knowledge and tools to contribute. This includes agriculture, which is considered to contribute about a third of emissions globally. This paper reports on one such tool: IMPACCT: Integrated Management oPtions for Agricultural Climate Change miTigation. The paper aims to discuss these issues. Design/methodology/approach – IMPACCT focuses on GHGs, carbon sequestration and associated mitigation options. However, it also attempts to include information on economic and other environmental impacts in order to provide a more holistic perspective. The model identifies mitigation options, likely economic impacts and any synergies and trade-offs with other environmental objectives. The model has been applied on 22 case study farms in seven Member States. Findings – The tool presents some useful concepts for developing carbon calculators in the future. It has highlighted that calculators need to evolve from simply calculating emissions to identifying cost-effective and integrated emissions reduction options. Practical implications – IMPACCT has potential to become an effective means of provided targeted guidance, as part of a broader knowledge transfer programme based on an integrated suite of guidance, tools and advice delivered via different media. Originality/value – IMPACCT is a new model that demonstrates how to take a more integrated approach to mitigating GHGs on farms across Europe. It is a holistic carbon calculator that presents mitigation options in the context other environmental and economic objectives in the search for more sustainable methods of food production.

The City

In the Middle East and North Africa (MENA) region, studies focused on the relationship between urban planning practice and climatology are still lacking, despite the fact that the latter has nearly three decades of literature in the region and the former has much more. However, such an unfounded relationship that would consider urban sustainability measures is a serious challenge, especially considering the effects of climate change. The Greater Cairo Region (GCR) has recently witnessed numerous serious urban vehicular network re-development, leaving the city less green and in need of strategically re-thinking the plan regarding, and the role of, green infrastructure. Therefore, this study focuses on approaches to the optimization of the urban green infrastructure, in order to reduce solar irradiance in the city and, thus, its effects on the urban climatology. This is carried out by studying one of the East Cairo neighborhoods, named El-Nozha district, as a representative case of the most impacted neighborhoods. In an attempt to quantify these effects, using parametric simulation, the Air Temperature (Ta), Mean Radiant Temperature (Tmrt), Relative Humidity (RH), and Physiological Equivalent Temperature (PET) parameters were calculated before and after introducing urban trees, acting as green infrastructure types that mitigate climate change and the Urban Heat Island (UHI) effect. Our results indicate that an optimized percentage, spacing, location, and arrangement of urban tree canopies can reduce the irradiance flux at the ground surface, having positive implications in terms of mitigating the urban heat island effect.

Demoralizing: integrating J.D. Peters’ communication “chasm” with Niklas Luhmann’s (1989) ecological communication to analyze climate change mitigation inaction

Purpose The purpose of this paper is to explain the US society’s insignificant mitigation of climate change using Niklas Luhmann’s (1989) autopoietic social systems theory in ecological communication. Specifically, the author’s analysis falls within the context of Luhmann re-moralized while focusing on particular function systems’ binary codes and their repellence of substantive US climate change mitigation policy across systems. Design/methodology/approach The author achieves this purpose by resituating Luhmann’s conception of evolution to forgo systems teleology and better contextualize the spatial-temporal scale of climate change; reinforcing complexity reduction and differentiation by integrating communication and media scholar John D. Peters’s (1999) “communication chasm” concept as one mechanism through which codes sustain over time; and applying these integrated concepts to prominent the US climate change mitigation attempts. Findings The author concludes that climate change mitigation efforts are the amalgamation of the systems’ moral communications. Mitigation efforts have relegated themselves to subsystems of the ten major systems given the polarizing nature of their predominant care/harm moral binary. Communication chasms persist because these moral communications cannot both adhere to the systems’ binary codes and communicate the climate crisis’s urgency. The more time that passes, the more codes force mitigation organizations, activist efforts and their moral communications to adapt and sacrifice their actions to align with the encircling systems’ code. Social implications In addition to the conceptual contribution, the social implication is that by identifying how and why climate change mitigation efforts are subsumed by the larger systems and their codes, climate change activists and practitioners can better tool their tactics to change the codes at the heart of the systems if serious and substantive climate change mitigation is to prevail. Originality/value To the author’s knowledge, there has not been an integration of a historical communication concept into, and sociological application of, ecological communication in the context of climate change mitigation.

The Relationship

Global large-scale urbanization has a deep impact on climate change and has brought great challenges to sustainable development, especially in urban agglomerations. At present, there is still a lack of research on the quantitative assessment of the relationship between urban scale and urban expansion and the degree of the urban heat island (UHI) effect, as well as a discussion on mitigation and adaptation of the UHI effect from the perspective of planning. This paper analyzes the regional urbanization process, average surface temperature variation characteristics, surface urban heat island (SUHI), which reflects the intensity of UHI, and the relationship between urban expansion, urban scale, and the UHI in the Beijing–Tianjin–Hebei (BTH) urban agglomeration using multi-source analysis of data from 2000, 2005, 2010, and 2015. The results show that the UHI effect in the study area was significant. The average surface temperature of central areas was the highest, and decreased from central areas to suburbs in the order of central areas > expanding areas > rural residential areas. From the perspective of spatial distribution, in Beijing, the southern part of the study area, the junction of Tianjin, Langfang, and Cangzhou are areas with intense SUHI. The scale and pace of expansion of urban land in Beijing were more than in other cities, the influencing range of SUHI in Beijing increased obviously, and the SUHI of central areas was most intense. The results indicate that due to the larger urban scale of the BTH urban agglomeration, it will face a greater UHI effect. The UHI effect was also more significant in areas of dense distribution in cities within the urban agglomeration. Based on results and existing research, planning suggestions are proposed for central areas with regard to expanding urban areas and suburbs to alleviate the urban heat island effect and improve the resilience of cities to climate change.
