Satellite-Sharing Enables Low-Cost Earth Observation

In August, Oleksii Kryvobok walked through a green and yellow field of sunflowers south of Kyiv, Ukraine, and measured the harvest’s photosynthetic activity with a device on a tripod. Hundreds of kilometers overhead, the EOS SAT-1 satellite, launched by Kryvobok’s employer, EOS Data Analytics (EOSDA), in Mountain View, California, was making the same measurements from orbit. 

The satellite, one of a planned fleet of seven, was joined in orbit in early November by a pair of competing Open Cosmos satellites. EOSDA and Open Cosmos are part of an emerging trend for earth observation (EO) satellites: they aim to use mini-constellations of small satellites to offer specialized EO data in much the same way bigger companies such as Planet and Maxar offer high resolution optical data to customers of all kinds.

Translated story: The share of Europe’s territory at high risk of fire has doubled in the last 50 years

Portugal, Spain, Greece and Italy come up every year when we talk about major forest fires. You don’t have to look far back to remember catastrophes such as the fire in Rhodes, Greece, last July, that displaced 30,000 people. Or the Pedrógão Grande fire in 2017, in Portugal, that killed 66 people. The Mediterranean is a hot spot for climate change, and a hot spot for forest fires.

An increasing number of European countries are experiencing very high or extreme forest fire risk. This is a new problem for some of them. In recent years, forest fires have also become more severe in central, eastern and northern European countries. 2018 was a particularly bad year for Sweden. Sweden experienced very high fire weather risk, on average, in 49% of its territory that year, and extreme risk, the highest level, in 14% of its territory. This was a record for the last five decades. That same year, a record number of hectares burned across the country, far more than had burned in any year during the previous decade.

Europe now has twice as much territory at very high or extreme fire weather risk as it did in 1971: 40 percent, up from 20 percent. This means that populations that were not previously at high risk – or at all – are now at high risk of enduring a wildfire. This index, the fire weather index, measures the weather conditions that enable a fire to spread. It incorporates humidity, wind, temperature and precipitation, but does not include other very important variables such as vegetation. To know the real fire danger, fire weather risk is only one part: “Part of it depends on the weather, part of it depends on the fuel and its flammability, which also depends on its moisture content,” says Carlo Buontempo, Director of the Copernicus Climate Change Service (C3S).

How Nigerian Hacktivists Are Taking on Big Oil 

A group of hacker-activists in Nigeria, in the wake of setbacks in the conventional court system, have taken their appeal to a higher authority—the court of public opinion. And to bolster their case that oil refinery pollution is harming the densely populated Niger Delta region, these hacktivists are engaging in their own campaign of DIY data collection and sharing. 

Last March, Shell won a victory in one of its many court battles over the environmental impacts of its oil drilling in the Niger Delta. A U.K. judge ruled that the plaintiffs from the West African nation couldn’t prove that a 2011 oil spill in Nigeria’s offshore Bonga oil field had been the direct source of harm. The judge didn’t reject the existence of the harms, or even that they were caused by oil spills. Instead, the problem was attributing the harm to that specific spill.

Now, the Media Awareness and Justice Initiative (MAJI), a civil society organization in Port Harcourt, Nigeria, is building a low-cost air pollution monitoring network that could help better identify polluters. “Data has been the key,” in other, successful lawsuits, says Okoro Onyekachi, a filmmaker and the executive coordinator of MAJI. And now, he says, in MAJI’s own lawsuit for pollution reparations, as much data as possible will be needed. Starting in 2022, the group began installing the first of 15 air-quality sensors in and around Port Harcourt, Nigeria’s fifth largest city. The sensors are a mix of cellular-enabled and noncellular devices that monitor particulate matter alongside temperature, humidity, and atmospheric pressure.
