Automated Detection of Hazards

Countless phenomena such as floods, fires, and algae blooms routinely impact ecosystems, economies, and human safety. Your challenge is to use satellite data to create a machine learning model that detects a specific phenomenon and build an interface that not only displays the detected phenomenon, but also layers it alongside ancillary data to help researchers and decision-makers better understand its impacts and scope.

Capybara Project

Summary

2020 is being a tough year filled with catastrophes. Many of them are related to wildfires that continue to spread throughout the world. These fires are destroying our forests, killing the animals, and endangering everyone´s lives as their sizes continue to grow. This project is aimed to classify previous fires based on their location, environment conditions, and socio-ecological impacts during the fire and predict when those conditions will happen again in the future, enabling decision makers to mitigate, prevent and prepare for the upcoming fire seasons.

How We Addressed This Challenge

Wildfires needs three components to occur: the right weather, abundance of inflammable objects, and a spark. As the planet continues to demonstrate even more clear signs from the global warming, this combination will happen more frequently. There are two opposite scenarios that demonstrate how and why this phenomena is occurring with more intensity:




  • Wet and densely forested ecosystem has a large amount of fuel. A single wet season is irrelevant for the increase of the fuel and the soil moisture limits the risks for wildfires. However, as the dry seasons continue to get drier and hotter, soil moisture is set to diminish. Having this abundance of inflammable objects and the right climate conditions, all it takes to a fire to start is a spark. A recent study made by the Colorado University shows that 59% of the wildland fires were started by human activity and this number is even higher in areas with human population. Furthermore, with the advance of global warming, lightning strikes are becoming even more frequent, increasing the risk of natural sparks as well.
  • Relatively dry ecosystems dominated by grass and low-density shrub offers a low amount of fuel and this limitates the spread of large fires. Should these ecosystems receive an above normal precipitation, the additional growth of the vegetation will increase the inflammable material and the excess moisture will be quickly dried out in the dry seasons. The spark risks are the same as mentioned before.


Wide-scale wildfires damage analysis should consider a wide array of variables, not only the burned area. Multi-dimensional metrics (such as carbon emissions, human lives lost, direct economic losses, potential hazards in air and water quality), that identifies the areas that have the most risk is essential for governments to promote landscapes that are more fire resilient and minimize risks for human populations and infrastructure.


As the fire seasons continues to get bigger and longer, firefighting needs to be more efficient. Fire suppression has already proven itself to have a poor efficiency. It is vital that the governments target their efforts in identifying the most susceptible areas to fire, taking steps to reduce the damage caused by the fire season.


The Capybara project aims to firstly identify which areas are in more danger based on historical satellite imagery and weather data. Then classify the level of danger these areas represent based not only on the area that was burned, but also on the climate effects for the region. Furthermore, in the future will be possible to classify the economical and humane damages. The project consists in creating an API to provide our analysis and a Power BI dashboard that consumes the analysis and enables researchers and policy makers to manipulate the data the way they desire.


This project has the goal to create a machine learning model that identifies which areas are more susceptible to wildfires, based on historical weather and fire data. Then classify the damage these fires caused to predict which area will eventually cause more damage in the future. As a result, policy makers would be able to focus on the mitigation, prevention and preparation for the fire season, by acting in the areas that are most critical for the firefighting. Finally, capybaras would be able to live worry free on the great brazilian wetlands.

How We Developed This Project

Brazilian flora has received a lot attention from the media as it is suffering with the worst widespread fires of the last decade. Millions of acres have been burned and the probability is that these fires continues to get worst every year. Capybaras are the largest rodents of the world and inhabitants of all of these environments that are being destroyed due to inefficient policies that were enforced by the government. Providing an easy visualization tool to change the population´s perception about the damages and that part of them could be avoided with the right efforts is of paramount importance to change the policy making in the future.


Agile methodologies were used to determine the scope of the project and to track the progress. After the scope was determined, there were some hardships finding the right datasets. A lot of knowledge bases from NASA were discovered in this process, as well as how some of NASA´s satellites, such as Aqua and Terra, works. Python analysis were made upon those datasets and provided on an API so that the Power Bi dashboard could consume it and manipulate it the way it intends.


On the whole, the most important learnings were about how fire seasons happens, what would be possible to do to avoid certain risks, and how to access and analyze satellite data.

How We Used Space Agency Data in This Project
  • NASA FIRMS fire occurences
  • Meteomatics weather API


These two dataset were crossed to identify the environment conditions and predict which areas are more susceptible to wildfires.


The following variables were analysed:



  • Location
  • Wind speed
  • Ambient temperature
  • Air moisture
  • Precipitation
