Background

Forest fires have been getting worse in recent years. According to a report by the WWF, the duration of fire seasons across the globe has increased by 19% on average. The fire season has been starting early in places, with an increase in the duration of the fire season over extensive areas. H2O.ai provided us with an opportunity to leverage data to analyse wildfire events and provide an AI-based solution. It is an interesting research area to see how AI can help in pre, intra as well as post-wildfire events.

Challenge

Trend analysis can help in wildfire prediction, but the external factors are continuously changing and with climate change, these factors have become more unpredictable than ever. Also, we won’t be able to predict other regions based on the dataset of a specific region as the occurrence of wildfire is subject to a lot of factors. We decided to try an offbeat approach and built an NLP app for the wildfire challenge.

Models Used:

EnvBert

We developed a PyPI package EnvBert and open-sourced it. It is an easy-to-use Python library built on top of Bert models to identify essential environmental data as a part of due diligence in environmental site assessments.

PyPI Link: https://pypi.org/project/EnvBert/ 

pip install EnvBert

DistilBERT

DistilBERT is a small, fast, cheap, and light Transformer model trained by distilling BERT base. It has 40% fewer parameters than bert-base-uncased and runs 60% faster while preserving over 95% of BERT’s performances as measured on the GLUE language understanding benchmark.

App

We designed an interface for users to input the location and date range. Based on the input, the deep learning  models extract the data about the cause, severity, and spread of wildfire as well as information about the extent of contamination and remediation activities.

The app provides links to the latest news articles pertaining to wildfires in the region.

The app displays the latest YouTube videos pertaining to wildfire for the location.

Target Audience

Our solution focuses on:

• Helping public and businesses by warning them about wildfire events that may have happened last week either in their area or surrounding neighbourhood and help them decide if they must migrate to safer areas.
• Helping tourists and joggers avoid trails that are in the affected area.
• Helping first responders in the wildfire surrounding neighbourhood to be alert.
• Helping the local leaders track the severity of wildfires that had happened in the past by selecting a date range. The app provides information if remediation goals were set by the leaders in charge at the time of the wildfire or if it needs to be set. It also helps them determine if there has been any remediation activity in the region.
