The Impact

The social housing sector is playing an important role in Brazil, due to the necessity of its expansion. Currently, many residential projects perform poorly in terms of energy efficiency and thermal comfort. In addition, the impact of climate change on energy consumption may aggravate the energy scenario, increasing the dependence on the heating, ventilation and air conditioning system. In parallel to this, there is a growing adoption of the Structural Concrete Insulated Panels (SCIP) and insulated concrete form (ICF) in the Brazilian construction industry, due to their advantages in reducing construction time, and cost. Therefore, this study provides a discussion on thermal-energy performance focusing on parametric analysis of the SCIP and ICF wall systems adoption for social housing in Brazil. Due to the fact that building performance is heavily affected by weather conditions, this study evaluated the computer simulation of the thermal-energy performance of SCIP and ICF wall systems for hot climates while addressing the impacts of climate change. The city of Rio de Janeiro, characterized by the tropical climate was selected, and the Climate Change World Weather File Generator (CCWorldWeatherGen) tool was used to produce weather data for future climate scenarios, such as 2020, 2050 and 2080.

<div> <p>The impact of climate change on water resources through increased evaporation combined with regional changes in precipitation characteristics has the potential to affect mean runoff, frequency and intensity of floods and droughts, soil moisture and water supply for irrigation and hydroelectric power generation. The Ganga-Brahmaputra-Meghna (GBM) system is the largest in India with a catchment area of about 110Mha, which is more than 43% of the cumulative catchment area of all the major rivers in the country. The river Damodar is an important sub catchment of GBM basin and its three tributaries- the Bokaro, the Konar and the Barakar form one important tributary of the Bhagirathi-Hughli (a tributary of Ganga) in its lower reaches. The present study is an attempt to assess the impacts of climate change on water resources of the four important Eastern River Basins namely Damodar, Subarnarekha, Mahanadi and Ajoy, which have immense importance in industrial and agricultural scenarios in eastern India. A distributed hydrological model (HEC-HMS) has been used on the four river basins using HadRM2 daily weather data for the period from 2041 to 2060 to predict the impact of climate change on water resources of these river systems.&nbsp;</p> </div> <p>&nbsp;</p>

The Impact

Urbanization trends have changed the morphology of cities in the past decades. Complex urban areas with wide variations in built density, layout typology, and architectural form have resulted in more complicated microclimate conditions. Microclimate conditions affect the energy performance of buildings and bioclimatic design strategies as well as a high number of engineering applications. However, commercial energy simulation engines that utilize widely-available mesoscale weather data tend to underestimate these impacts. These weather files, which represent typical weather conditions at a location, are mostly based on long-term metrological observations and fail to consider extreme conditions in their calculation. This paper aims to evaluate the impacts of hourly microclimate data in typical and extreme climate conditions on the energy performance of an office building in two different urban areas. Results showed that the urban morphology can reduce the wind speed by 27% and amplify air temperature by more than 14%. Using microclimate data, the calculated outside surface temperature, operating temperature and total energy demand of buildings were notably different to those obtained using typical regional climate model (RCM)–climate data or available weather files (Typical Meteorological Year or TMY), i.e., by 61%, 7%, and 21%, respectively. The difference in the hourly peak demand during extreme weather conditions was around 13%. The impact of urban density and the final height of buildings on the results are discussed at the end of the paper.

Purpose The purpose of this paper is to study the relationship between tourism and climate change and, hence, to understand the impact of climate change on tourist destinations. Design/methodology/approach A conceptual analysis of secondary data was extracted and analyzed. The framework and policy implications for the study were obtained from online secondary data and by interaction with representatives of a state authority. Findings The findings from the study show that the impact of climate change on tourism is likely to manifest itself in a number of different ways according to local conditions. Climate and weather are connected with tourism and recreational activities. The paper shows the importance of climate for tourism because climate itself is an attraction. Climate and weather are among the most important attributes to influence tourist decision-making. Changing the climate and weather conditions of any destination may affect the tourists’ comfort and travel decisions, and due to the changing demand pattern and tourist flows, tourism businesses and host communities suffer. Cancellation of any trip due to bad weather causes dissatisfaction and those affected may avoid visiting the destination again. Temperature is also one of the most important climate variables in the analysis of tourism demands as it affects comfort. Originality/value This original piece of work suggests that climatic conditions control destination choice and this influences the tourism demands for a given destination.

The Impact

Climate change is reflected in changes in average weather conditions and the more frequent occurrence of extreme conditions. It also affects the field of road transport and shows impacts both on traffic and road users as well as on the road infrastructure itself. The main objective of this work is therefore to evaluate the impact of climate change on the performance of road infrastructure (pavements) and to educe recommendations through proposals for adaptation measures. The impacts of climate change on road infrastructure result in changes in some road design parameters (average temperatures, radiation index, etc.). The different cases of cracking (fatigue or other) are assessed separately using degradation indices for each layer composing a pavement (surface layer, base layer, stabilized layer, etc.)

The Impact

Climate change is attracting increasing attention from the international community. To assess the impact of climate change on China’s rice production, this paper re-organizes the main rice-producing areas by adding up the annual production of the provincial level regions between 1979 and 2011, utilizes Cobb–Douglas function using daily weather data over the whole growing season. Our analysis of the panel data shows that minimum temperatures (Tmin), maximum temperatures (Tmax), temperature difference (TD) and precipitation (RP) are the four key climate determinants of rice production in China. Among these, temperature difference is surprisingly significant and all except maximum temperatures have positive effects. However, because the actual minimum temperatures and precipitation in China’s main rice-producing areas declined while the maximum temperatures and the temperature difference increased during our sample period, climate change has actually provided a negative contribution to the increase in China’s rice production.
