Earth Saw Record-High Greening in 2020

“The year 2020 was the greenest in modern satellite records from 2001 to 2020, according to a recent study published in Remote Sensing of Environment. Consistent growth in northern and temperate regions, combined with a brief period of tropical growth, primarily led to this remarkably verdant period…

To tease out the drivers of Earth’s green-up, they used machine learning and ecological simulations to explore how different environmental and human factors might have affected vegetation growth. Contrary to expectations, pandemic-related lockdowns had a limited effect on global greening…

The team found that 2020’s record-high greening was instead primarily associated with temperate and colder regions, fueled by rising CO2 levels, climate warming and reforestation efforts. The effects of climate warming were most prominent in cooler areas, such as boreal forests, where rising temperatures extended growing seasons.”

Ethiopia’s Forest Cover Is Rising as Deforestation Slows

“Over the last century, Ethiopia nearly eradicated its forests as trees were cleared for farming, grazing, and fuel. The loss of tree cover and tree roots allowed wind and rain to wash away fertile topsoil and contributed to declining crop yields…

Now the country is trying to reverse this trajectory…

The government reports that national forest cover rose from 17.2 percent in 2019 to 23.6 percent in 2023, while studies of restored areas have found substantial reductions in soil erosion. Between 2013 and 2023, the annual deforestation rate fell from more than 350 square miles to around 100 square miles.”

Brazilian Amazon Deforestation Falls to Lowest Level in 13 Years

“Deforestation in the Brazilian Amazon has fallen to its lowest level in 13 years, according to new satellite data from Brazil’s National Institute for Space Research (INPE), continuing a decline that began after President Luiz Inácio Lula da Silva returned to office in 2023.

INPE’s DETER alert system detected 2,874 square kilometers (1,110 square miles) of deforestation in the Amazon between August 1, 2025, and July 31, 2026. That was 36% below the previous 12-month period and 55.6% below the average of the preceding decade.

The total is the lowest since INPE introduced the current DETER system in 2015. Including data from its predecessor system, the last time alerts were lower was the 2012/13 deforestation year, when 2,766 sq km were recorded.”

In Italy, Forests Occupy a Third of the Territory, and Are Increasing

“Today, Italy is, in all respects, a forestry nation. The wooded areas have in fact exceeded 100 thousand square kilometers of extension and occupy over a third of the national territory. A figure that marks a significant change, for which from 2020 the forest area has exceeded the agricultural one used: a situation that had not been recorded since the Middle Ages. To photograph this transformation is the report Foreste in Comune, the first socio-economic survey on the forest heritage of the Italian municipalities promoted by PEFC Italia. The analysis shows that the forest has become a central component of the Italian landscape, with a whole series of benefits that derive from the increasingly widespread presence of forest ecosystems.”

Earth’s Mangrove Forests Expand and Regrow over Four Decades

“Mangrove forests are coastal habitats that serve as nurseries for economically important fisheries. Natural disturbances such as cyclones and shore erosion, together with aquaculture, palm plantation, and rice paddy expansion, have led to global declines in mangrove forest cover, spurring national and international pledges to restore it. Zhang et al. created a 30-meter-resolution annual dataset from satellite imagery to assess how mangrove occurrence and canopy cover have changed from 1984 to 2023. Mangroves declined globally before 2010, but have mostly recovered since then, with both forest loss and degradation (declining canopy cover) rates slowing over time. Mangroves are mostly expanding into new habitats, but also regenerating in former habitat, suggesting hope for ecosystem recovery”
