These Drones May Be the Solution to Our Global Deforestation Crisis

The world burns or cuts down about 15 billion trees a year through mining, logging, and urban development. However, no nations, organizations, or individuals “have been able to plant enough trees to make up for that loss,” according to National Geographic, which results in not nearly enough trees being seeded to combat deforestation.

With big implications for climate change, an increase in mass deforestation threatens the survival of millions of animal and plant species. But as ecological initiatives push to regrow forests and farms like, technology startups may finally have an answer: drones.

NASA veteran Dr. Lauren Fletcher is one of many new tech entrepreneurs using modern machinery, soil-testing, computers and ground-based sensors to make crop monitoring and tending more efficient. Fletcher created BioCarbon Engineering (BCE) to fight deforestation on a mass scale, describing BCE as an ecosystem restoration company that primarily employs an unmanned aerial vehicle (UAV) nicknamed “Robin.”  

The 30 lb. Robin drone can fly over the most rugged landscapes on earth, while also planting trees at the rate of 120 per minute. Robin drones scan the terrain and develop a 3D map of the area. Then using data from a developed “smart map,” the team uses an algorithm to carry out the planting strategy. With precise targeting, Robins gently fire seed pods into the earth at a dizzying rate of two per second.

Even after Fletcher put together a team of 12 experts with backgrounds in engineering, community development, ecology, biology, and remote sensing to form BCE, he still had to find the right species of tree: “This is about restoration of local ecosystems, full stop. If you don’t get the biology side right, then you’re not a solution. This isn’t just a convergence of technology. It’s actually a convergence of social will and political power that are all focused on this global problem.”

Speed is the most revolutionary aspect drone seeding and the future of “precision planting” technology. Precision agriculture or smart farming is based on the use of advanced technology in the management of any plants or crops to increase output without compromising quality. Even more promising, drone seeding has the potential to plant 500 billion trees by 2050.

Ecosystem restoration is proving to not only combat climate change, but quickly becoming an emerging and lucrative business opportunity. The need to maintain the balance between cost and quality has made drones particularly attractive for smart farming and reforestation. Drones are affordable and don’t require much training to pilot, but pilots do need certification.

Federal rules around drones were loosened late last year, and special permits were issued to a handful of agriculture operators. As that number grows, the impact on the US farm sector will be huge: The American Farm Bureau Federation estimates farmers’ return-on-investment alone may be $12 per acre for corn and $2 to $3 per acre for soybeans and wheat—which is a lot. And the United Nations projects, assuming a global population of 9.1 billion people in 2050, food production will need to rise steadily by about 70 percent. Improving crop yields will be increasingly key to feeding the starving world, in which drones could play a vital role.

The value of drone-powered solutions in agriculture is estimated at $34 billion, according to a recent PwC analysis; drones can improve food production, increase crop yields, and help a farm’s overall productivity rate. More ecologically-minded tech startups like DroneSeed in Seattle, Washington, are already developing plans to plant seeds; they currently use drones to spread fertilizer and spray herbicide with a multispectral camera that allows farmers to take field shots and identify the state of vegetation. Drone-seeding data identifies problem areas in agricultural fields and consequently monitors the level of germination. Afterward, drone-driven soil analysis provides data for proper irrigation and nitrogen-level management.

Vast fields and low efficiency in crop monitoring have always been farming’s largest obstacle. Monitoring challenges are exacerbated by increasingly unpredictable weather conditions, which drive risk and raise field maintenance costs.

Previously, satellite imagery offered the most advanced form of monitoring. But images had to be ordered in advance, could only be taken once a day, and image quality typically suffered. Now drones with hyperspectral, multispectral, or thermal sensors can identify which parts of a field are dry or need improvements.

In recent years, hundreds of companies have entered the forest and farm restoration industry, but now drones can deliver on a definitive promise to restore agricultural lands.  


Shortly after House Speaker Nancy Pelosi (D-CA) announced that representatives would begin drafting articles of impeachment against President Donald Trump, House Minority Leader Kevin McCarthy took the podium to defend the President and the Republican party as a whole.

It could've gone better.

One day after the House Judiciary Committee's hearing on impeachment, House Speaker Nancy Pelosi (D-CA) held a press conference announcing that the House would begin drafting articles of impeachment, with a possible floor vote as soon as Christmas.

The press conference signaled the beginning of the end of the impeachment inquiry in the House.

The House Judiciary Committee, in its public impeachment hearing against President Donald Trump on Wednesday, consulted four constitutional scholars for greater insight to the legal implications of the President's Ukraine scandal—and whether they merit impeachment.

Three witnesses, called by Democrats, each made compelling arguments for the articles of impeachment with which Trump could be charged.

George Washington University professor Jonathan Turley—invited by Republicans—was the lone dissenter.

The Republican Party again raised ire and eyebrows with yet another GOP candidate advocating violence against members of Congress in official campaign materials.

This time it is George Buck Jr. of Florida. The GOP politician is running for the 13th congressional district—a seat currently held by Democrat Charlie Crist.

President Donald Trump's press team is working overtime to discredit media coverage of the impeachment hearings against their boss.

The House Judiciary Committee began its hearings today, with four constitutional scholars—Pamela Karlan, Michael Gerhardt, Noah Feldman, and Jonathan Turley—tasked with testifying about the constitutionality of impeaching Donald Trump. The former three were invited by Democrats, who hold the majority, while Turley was invited by Republicans.

The House Intelligence Committee submitted to the House Judiciary Committee its 300 page report of information gleaned from fact witnesses so far in the ongoing impeachment inquiry against President Donald Trump.

In addition to reiterating the testimony of several witnesses regarding Trump's corrupt dealings with Ukraine, the report also highlighted call records between numerous key players in the Ukraine scandal.
