In this project, we will use a newly developed system to tackle the air pollution hazard in Nicaragua. Air pollution is the largest environmental root of ill-health and premature loss of life. Each year it causes over 4 million deaths, with 90% of these in developing countries. Air pollution stems both from anthropogenic activities as well as a variety of natural sources. In the developing countries air pollution is generally poorly understood due to lack of scientific research and routine monitoring. Furthermore, while public air quality (AQ) alerts and advisories are legally mandated in the UK and other high-income countries, they are almost non-existent in the poorest parts of the world. The World Health Organisation therefore recommends that monitoring of air pollution is improved in the developing countries to better understand the impact it has on health, and to assist local authorities in establishing plans for improving AQ. In a previous research project, our team looked at a poorly understood source of air pollution from persistently active volcanoes, using Masaya volcano in Nicaragua as a case study. Volcanic air pollution (VAP) is a chronic natural hazard potentially present in over 30 countries on the Official Development Assistance list but absent from their mitigation strategies. Almost nothing is known about the interaction of VAP with anthropogenic air pollution and the resulting impacts on health and the environment. Our previous project developed and trialled a system for monitoring VAP and assessed ways of making the system suitable for operational use. This new system can be used for monitoring AQ both from volcanoes and other sources, including anthropogenic activities such as traffic.We will install a network of permanent AQ stations that will stream data in real-time to the Nicaraguan natural hazards observatory. We will also introduce techniques and tools for visualising and interpret the data. Nicaragua already has a well-developed system for monitoring and mitigating a number of other natural hazards, such as earthquakes, hurricanes and tsunami. The AQ network will be integrated with the pre-existing system and used alongside monitoring of other hazards. We will be collaborating with the Nicaraguan natural hazards observatory, the civil protection, and multiple other local and international end-users.The AQ data will be used to make forecasts and issue public advisories for unhealthy air pollution levels. Public advisories allow the decision makers and the public to take measures to protect the most vulnerable persons, such as people with respiratory and heart conditions, children and the elderly. AQ monitoring also increases the awareness of decision makers and the public on air pollution issues, and is therefore an important initial step towards improving AQ in the country. We will be working closely with the local communities to ensure that the public advisories are applicable, easily understandable, and useful for their lifestyle. At the end of the project, the local end-users, such as the natural hazards observatory, will have the necessary capability and knowledge to run the AQ network and expand it as needed.
