“…Flood risk was one of the main priorities in the Plan, identifying and delimiting eight hotspots according to the road network of the city (Ayuntamiento de Santander, ), which were prioritised based on the vulnerable elements and consequences associated with them. In line with previous studies involving areas of influence to model urban phenomena (Jato‐Espino, Castillo‐Lopez, Rodriguez‐Hernandez, & Ballester‐Muñoz, ; van Hove et al, ), buffer areas of 250 m were delimited around the roads indicated in the Plan to represent these hotspots. Figure shows the position of these buffer areas throughout the city, including the streets, avenues, plazas, roundabouts, and tunnels contained in them.…”

Floods are one of the most common and harmful natural disasters worldwide, especially in cities, due to the high concentration of people and goods in these areas.This research aims to provide an accessible and accurate means to model risks associated with floods in urban spaces using open data about a series of susceptibility and impact contributing factors. Hence, a methodology combining geoprocessing tools, additive weighting, dependence measures, and optimisation was designed to generate spatial information, aggregating the factors according to their weights and optimising the modelling of their relationships to flood risk, respectively. The application of the proposed approach to the city of Santander (Spain) yielded a flood risk map providing an accurate assessment of the ranking of flood zones reported by its City Council. The results suggested that flood mitigation might focus on the implementation of permeable pavements, due to their ease of integration in urban environments.

“…A partir de la ecuación [1] se especifica un modelo econométrico general para estimar las cinco regresiones que componen el análisis: lnCC t =α 0 + α 1 ln Msost t + α2 ln PV CFOSt-1 + α 3 lnTemp t + DumA 1-3 + e t [2] La única variable rezagada en el tiempo es la proxy del parque vehicular, el consumo de gasolina y diésel de los vehículos es lento y tiene un efecto en el tiempo. Los datos de contaminación del aire están referidos en términos de emisiones en partículas y gases (ppm y mg/m3) en lugar de utilizar un índice de calidad de aire como hacen otros estudios (Jato- Espino et al, 2018;Xiao et al, 2020). Para el caso mexicano el uso de este índice subestima el efecto de la contaminación.…”

The objective of this paper is to evaluate whether the low-carbon transport strategy (subway, rapid transit bus system -Macrobús-, trolleybus, and shared bicycles) implemented in the Guadalajara Metropolitan Area (AMG) from 2000 to 2019 improves air quality. Sustainable urban mobility is the movement of people in cities in a way that generates the least impact on the environment. We analyze three actions of government intervention in the same sense. This is the first study for Guadalajara, the third-largest city in Mexico. We use robust Newey-West estimators and endogenously model pollution disruptions using the Bai Perron approach. Our results suggest that this type of public transport reduces SO2, NO2, O3, and CO, though we find an increase in PM10. We also identified that when the service of the first line of the Bus Rapid Transit was consolidated CO, O3 and PM10 decreased. In addition, the improvement in the connectivity of the bus network with the subway means that only NO2 diminished. Finally, the entry into operation of the shared bicycle program reduced PM10, while increasing O3 and in SO2. In short, sustainable urban mobility is an alternative to making the transit of people efficient, while mitigating air pollution in the AMG.

“…The forecasting of air quality became popular, many methods have been purposed for forecasting air quality such as hidden Markov model [15], first-order and one-variable grey model [16], developed support vector machine [17], fuzzy time series model [18][19] [25], Solar Radiation [26], and Fuzzy-AHP [27].…”

In Indonesia, carbon monoxide is one of which type of gas used as a parameter in the air pollution. Unfortunately, reporting and monitoring air pollution in Indonesia is regulated in government rules and reported once a day. The value of carbon monoxide concentration always change but the published information is out of date. Without real-time information, people cannot avoid the danger of monoxide pollution toxicity effect. This paper purpose the solution by publishes the real-time information from the carbon monoxide sensor data acquisition. This Research uses the rule-based method to calculate carbon monoxide pollution from data acquisition. Results of experiments show that information generated by the system in accordance with the manual calculation results of carbon monoxide pollution. This research contributed to providing information on real-time carbon monoxide measurement to the public, so the danger of carbon monoxide poisoning can be avoided.
