Please also select the top 3 assets or services that are affected by the climate hazard, and provide a description of the impact.10Impact description4Although there are other factors associated with global change that directly impact on fire risk, the increase in temperatures and decrease in precipitation caused by the effects of climate change, which will lead to plants suffering increased hydric stress, increasing their flammability, will favour an increase in the risk of forest fire. The future danger of fire shows us a situation similar to current danger, but with a slight overall increase in danger. The change in danger with the addition of climate change means an overall worsening across the territory, but with no specific area standing out particularly in terms of increased risk of more fires.

Please also select the top 3 assets or services that are affected by the climate hazard, and provide a description of the impact.10Impact description5The projections show that the effects of climate change could lead to an increase in the annual concentration of the three pollutants analysed. The increase would be greatest in PM10 particles, average in NO2 and minimal in O3. All in all, under the hypothesis that emissions would be maintained, since it has not been possible to quantify its evolution over time. There has, however, been a downward trend in recent years, a foreseeable technological improvement, and changes in patterns of consumption and energy model are anticipated, which may have a significant impact on emissions levels in the future.

Please also select the top 3 assets or services that are affected by the climate hazard, and provide a description of the impact.10Impact description6With regard to hot days (temperatures above 30ºC), Barcelona currently has an average of 22 days a year. Current models suggest an increase to 50 days a year by the end of the century for thecommitted scenario and 80 days a year for the passive scenario. In both scenarios, the areas most affected by high temperatures are those furthest from the sea, as its thermoregulatory effect does not reach them. For the extreme case of torrid days (temperatures above 35ºC), the current average is nearly 1 day every 2 years. Under the committed scenario, simulations indicate that these phenomena will increase by approximately 2 days a year, while under the passive scenario the predicted increase will be 8 days.

Please also select the top 3 assets or services that are affected by the climate hazard, and provide a description of the impact.10Impact description7Most projections indicate that there may be an increase in rainfall intensity and a greater concentration of extreme episodes. Increased rainfall intensity may cause certain areas of the city to flood, as it will increase the flow of circulating water and test the city's drainage system to its limits.

Please also select the top 3 assets or services that are affected by the climate hazard, and provide a description of the impact.10Impact description8The general trends observed indicate that, among other things, there are two impacts associated with climate change that may affect flood risk: changes in rainfall patterns and rising sea levels.Regarding the former, most projections indicate that there may be an increase in rainfall intensity and a greater concentration of extreme episodes. Increased rainfall intensity may cause certain areas of the city to flood, as it will increase the flow of circulating water and test the city's drainage system to its limits.The second aspect is higher sea levels, which may condition the functioning of the drainage system in extreme situations. Under extreme conditions, an increase in sea level would mean that the overflow channels would not work properly, causing higher water levels in the network that could cause overflow at the surface, and therefore flooding in the street.
856Cities 20181499Ajuntament de BarcelonaSpainEuropeClimate Hazards2.2aPlease list the most significant climate hazards faced by your city and indicate the probability and consequence of these hazards, as well as the expected future change in frequency and intensity. Please also select the top 3 assets or services that are affected by the climate hazard, and provide a description of the impact.10Impact description9The sanitation network would be one of the infrastructures most affected as a result of climate change in the most extreme scenario. These impacts would mainly lead to an increase risk of flooding from rivers, in urban areas or due to rising sea level. Overflows may be affected, but data on these overflows is not available to determine the specific extent to which they would be affected. It would also aggravate the impact on the drinking water network and, to a lesser extent, on the phreatic network. It could also lead to the entry of sea water, rendering the aquifer unusable (saline intrusion).Road and railway networks are particularly exposed to floods and fires. These infrastructures are very affected by almost all risks, but particularly fires and river and urban flooding. In the first two cases structural and strategic city access infrastructure could be affected. Currently fire risk affects 1,000 km of the road network, with the risk considered high and 39% of the railway network is also affected by high risk to fires (both roads and railway lines).Forest fires pose the greatest risk to energy infrastructureThis risk already exists today, although it is expected that the impact of climate change will slightly worsen the trend compared to the current situation. This impact is mainly felt on electricity lines located in Collserola Park, but the greatest risk is to infrastructure in the metropolitan area, with a lower incidence in Barcelona. Fire risk affects 96% of overhead electricity lines and 44 substations, all considered high risk. Barcelona's wholesale market could find itself at high risk from river flooding. Barcelona's wholesale market would find 41% of its surface area at high risk, according to passive scenario projections, by the end of the century. River flooding would also have a fair amount of impact on basic services such as energy and water, mainly due to dragging materials that could affect infrastructure, including underground, but in this case to a lesser extent. It is hoped that in the climate change scenario considered, the risk variation is slight or moderate in the sense of aggravating risk.

The effect of temperature or the loss of seasonality as a result of climate change have a multiplying effect on some pest species. Populations of mosquitoes, cockroaches, monk parakeets and rodents (mice and rats) are on the increase and, as a result, the risk of transmission of the diseases they carry increases, which could lead to public health issues.In order to combat these pests and infestations research into techniques for fighting them, whilst also reducing the use of pesticides, will need to be intensified.Temperature increases can also cause an increase in the multiplication rate of mosquitoes carrying diseases such as Dengue fever, Zika, chikungunya and West Nile virus.

Please also select the top 3 assets or services that are affected by the climate hazard, and provide a description of the impact.10Impact description14In order to study flooding caused by the sea, the height of flooding is calculated. This is determined by three factors: the rise in sea level that causes a permanent flood; the tide and pressure and wind changes that generate a potential flood; and finally the effect of waves, which cause extreme flooding. Waves are currently responsible for causing major problems along the Barcelona coastline during extreme storm conditions.Climate projections show that there will be a general rise in sea level as a result of melting polar ice caps and heat expansions, and this increase will bring changes depending on the region. In addition, extreme events are predicted to be more frequent, although their magnitude will not change much. In the case of Barcelona, which previously was associated with return periods of 50 years, periods of 35 years are forecast by 2050.Regarding the Barcelona coastline, although there are still not many studies that analyse the specific effect of climate change on the coastal dynamics of the area, approximations have been carried out that show that there is likely to be a triple impact on the coast as a result of climate change: an increase in flooding, morphological changes to the beaches and greater exposure of port infrastructures.
