Volcanoes are one of the most unpredictable and impressive natural phenomenons. Worldwide researchers and scientists have always been trying to discover what happen inside volcanoes to predict future eruptions that will save lives. Their activity has provoked along years great disasters destroying entire settlements with lava flows and also endangering the environment or human health due to gas emanations or ash falls. Some vulcanologists are currently focused on working with the latest technology to monitor in real-time everything that happens inside and outside the crater to predict eruptions. Qwake, a global brand that merges ground-breaking scientific expeditions with cutting edge technology to drive positive change, has trusted in Libelium technology to develop a wireless sensor network in the Mouth of Hell, Masaya volcano in Nicaragua.

Countries throughout the world have a need, and in many cases a legal obligation, to ensure air quality is meeting specific standards. Policies aim to reduce exposure to air pollution, by reducing emissions and setting limits and targets for AQI. Public authorities in cities have deployed static stations to monitor air quality data for a set of pollutant with specific, and high cost, sensing technologies. These stations provide highly accurate data but their cost limits the quantity of deployments, leaving large gaps in coverage.

Water and electrical supply are two of the main concerns for public authorities. The demand of these resources grow as fast as the population in urban areas so they would become scarcer with the pass of the years. A Technavio report states that the use of smart water management technologies such as Big Data, sensoring and monitoring in real-time can help save more than USD 12 billion revenues for utilities annually.

Municipalities and public institutions are concerned about air, water, noise or lighting pollution in cities. In the last years, it has become mandatory through several international regulations to reduce emissions that could impact in the environment and also inhabitants lives.Being a Smart City is more than just a trend, is a commitment with society and stakeholders.Carbon Track and Trace Project (CTT) aim is reducing CO2 emissions, combating climate change in cities and also developing a decision support system for cities greenhouse gas (GHG) emissions monitoring. It was funded by the Low Carbon City Lab flagship of the EU Climate KIC programme.
