Responding swiftly to wildfires is crucial, and the German-based company's Silvanet Wildfire Sensor aims to address this by providing timely alerts to mitigate potential damages. Citing data from the World Health Organization (WHO), which states that "wildfires and volcanic activities" impacted 6.2 million people from 1998 to 2017, resulting in 2,400 deaths worldwide due to suffocation, injuries, and burns. A recent study conducted by University College London highlighted the staggering economic impact of California's 2018 wildfires, estimating a cost of $148.5 billion to the US economy. This included direct losses and health costs in California totaling $59.9 billion, along with indirect losses of $42.7 billion due to disruptions in 80 industry sectors within the state, affecting power transmission, road and rail freight transport, pipelines, and other infrastructure-dependent sectors. Carsten Brinkschulte, the CEO of Dryad Networks, emphasized the significance of wildfires, attributing up to 20% of global CO2 emissions to them. He warned that without adequate attention and investment to address these increasingly severe wildfires, global temperatures could rise by more than 1.5°C. The Silvanet Wildfire Sensor, a compact, off-grid plastic device equipped with a solar cell, measures temperature, humidity, and air pressure. Additionally, it features a low-power air quality sensor with a gas sensing mode capable of detecting hydrogen, carbon monoxide, and other gases during the early stages of pyrolysis at the ppm level. Typically mounted on trees at a height of 3 meters, each device measures 19 cm by 8.2 cm, with a 6 cm by 6 cm solar panel on the surface, enclosed in an IP 67-rated weather and UV-proof casing. The device is pre-loaded with artificial intelligence for accurate wildfire detection, minimizing false positive alerts. These sensors connect to gateways, with each gateway accommodating approximately 100 sensors based on the topography. LoRaWan wireless data transmission facilitates communication between the devices and first responders. Dryad Networks has stated that the device can operate maintenance-free for up to 15 years, eschewing the need for batteries and avoiding the use of toxic or rare materials by relying on supercapacitors for energy storage. The emissions from wildfires contribute to a concerning cycle of hotter and drier climates, leading to an increased occurrence of wildfires. Data from the UN Environment Program predicts a potential 62% increase in burned areas if global temperatures rise by 2 degrees Celsius. If the world experiences a three-degree temperature increase, this figure rises to 97%. Moreover, emissions from wildfires are frequently inaccurately reported or omitted from nations' carbon reports, often dismissed as natural phenomena. Brinkschulte highlighted the human-induced nature of 80% of wildfires and emphasized that carbon neutrality relies on forest regrowth, a process that can take over a century. Omitting wildfire emissions from global CO2 inventories is not only inaccurate but, according to Brinkschulte, it is also cynical. Dryad Networks estimates that deploying 120 million of its sensors globally by 2030 could potentially save up to 3.9 million hectares of forest from burning and prevent the emission of 1.7 billion tons of CO2.
