Computer modelling can predict air pollution levels and provide insights into environmental factors

Computer modelling plays a crucial role in predicting air pollution levels and understanding the associated environmental factors. By leveraging advanced technologies such as machine learning, artificial intelligence, and high-performance computing, scientists and researchers can now make accurate predictions about air pollution and gain valuable insights.

One of the key advantages of computer modelling is its ability to process vast amounts of data from various sources, including meteorological parameters, emission rates, stack height, and traffic data. This comprehensive data gathering enables the creation of intricate models that simulate the complex physical and chemical processes through which air pollutants disperse and react in the atmosphere. These models are essential for air quality management and help authorities make informed decisions to maintain healthy air quality levels.

For instance, dispersion modelling is used to estimate the concentration of pollutants at ground level near emission sources. Photochemical modelling simulates the impacts of all sources by assessing the deposition and concentrations of chemically reactive and inert pollutants over large areas. Receptor modelling, on the other hand, employs observational techniques to identify and quantify the contributions of different sources to the overall air quality.

Computer modelling has been applied in various locations to predict pollutant concentrations. For example, a study in Stuttgart used machine learning methods to simulate the concentrations of PM2.5, PM10, and NO2. The results indicated that pollutant information from nearby monitoring stations significantly influenced the prediction accuracy. Similarly, machine learning techniques have been utilized in London to predict fine particulate matter (PM2.5) levels, demonstrating the adaptability of these models to different geographical contexts.

Furthermore, computer modelling can provide insights into the environmental factors influencing air pollution. For example, scientists use drones and high-performance computing to collect and analyze forest biomass data, helping them understand the factors affecting forest health and the resilience of different tree varieties to climate fluctuations. This knowledge is crucial for forest preservation and combating the effects of climate change, such as increased temperatures, droughts, and rising global temperatures.

Computational approaches help to create wildlife corridors, protecting biodiversity and reducing urbanisation impacts

Urbanization has resulted in the loss of wildlife from cities, which has a disproportionately negative impact on low-income communities and communities of color. This loss of biodiversity has important implications for the sustainable development of cities. As such, it is crucial to develop successful strategies for urban wildlife conservation that strengthen the virtuous cycle between biodiversity conservation and the people inhabiting cities, for the sake of both wildlife and humans.

Computational approaches have been instrumental in creating wildlife corridors, which are essential tools in conservation that connect wildlife populations that have become isolated due to human-mediated habitat fragmentation. By compiling vast amounts of data, scientists can create models of the areas inhabited by wildlife and predict where these corridors can be placed. This data is also used to determine how to design the corridors, ensuring the protection of wildlife connectivity in cities.

For instance, in a case study of urban wildlife corridor conservation along the eastern edge of the Rim of the Valley Corridor in the Metropolitan Los Angeles Area, a priority area was defined to create a database for researching and monitoring wildlife connectivity. Remote-triggered camera traps and community science observations of all terrestrial mammal species were used to track wildlife presence within the priority area. This data was then used to make evidence-based decisions for land acquisitions, with vacant privately owned land prioritized for conservation needs.

Additionally, computational approaches can be used to establish strict ecological protection red lines to ensure the preservation and restoration of critical habitats during urban development. This can be complemented by promoting nature-based solutions, such as constructing urban wetlands, green corridors, and ecological parks to enhance ecological connectivity.

Overall, by applying computational approaches to create wildlife corridors, we can protect biodiversity, reduce the impacts of urbanization, and foster harmony between humans and the natural world.
