Wildfires have always been a part of human history, but there has been a significant increase in their severity and frequency over the past few decades.

That is a lot of extra mouths to feed when there are already 690 million people going hungry, according to the Food and Agriculture Organization of the United Nations (FAO).
Cambridge engineers have used drones, handheld particle sensors and a new modelling framework to measure, map and characterise harmful shipping emission particles at both land and sea. It is the first time that multi-characteristic particle measurements – including lung deposited surface area (LDSA), black carbon, and particle number – have been performed in this way, and it is hoped that this research will inform environmental initiatives and support efforts to clean up the maritime sector.
