Brazil Supreme Court restarts the Amazon rainforest Fund

Former President Bolsonaro had blocked it in 2019. The country's highest court ruled that the financial vehicle must be operational again within 60 days. After his reelection at the end of October, Lula will thus have at his disposal a fund with credits worth more than $20 billion
Nitrogen is an essential soil resource, but its overuse, mostly related to fertilizer application, is a driver of pollution.

Soil nitrogen is the one responsible for water pollution

During rainy periods soil nitrogen in the soil is channeled into rivers, contributing to their contamination, a research from Nagoya University has found. The investigation thus denies the theory of atmospheric origin of water pollution

Climate, italian CNR: ice-free Arctic summer by 2050

A National Research Council study published in PNAS reconstructed changes in sub-polar sea ice cover in response to rapid climate warming of the last ice age. The answers offer an alarming scenario of the Arctic situation by mid-century

Drones open a new frontier in soil mapping

Drones equipped with light spectrometers can map the ground and explore otherwise inaccessible areas, Dutch researchers have found. This application can also provide crucial data for soil protection and remediation

Microorganisms are the common thread between soil and human health

Spread throughout the soil, bacteria, fungi and archaea make up 18 percent of the Planet's biomass. Their services are critical for humans and plants, a new research explains. But some critical factors put their resilience at risk
High fertilizers prices threaten agricultural productivity in some countries in Sub-Saharan Africa, such as Ethiopia, and Central America.

Soil mapping means more information and less fertilizers

An FAO project aims to gather information on soil nutrients to optimize the use of fertilizers in Sub-Saharan Africa and Central America. An initiative aimed at countering the impact of rising market prices
Soil is a complex system, say three British researchers. Today, a unified method for assessing its health still doesn't exist. Photo: Soil Science Attribution 2.0 Generic (CC BY 2.0)Soil Science Attribution 2.0 Generic (CC BY 2.0)

British researchers propose a new theory of soil health

If we want to analyze soil health, we cannot rely on single indicators, says a new paper by Cranfield and Nottingham Universities. Instead, we need to focus on the relationships among the components of the system to get a complete picture. At the center of the new approach are four different dimensions
Peatlands in the Congo Basin cover more than 167 thousand square kilometers, 15 percent more than previously estimated. Photo: Dicklyon Attribution-ShareAlike 4.0 International (CC BY-SA 4.0)Dicklyon Attribution-ShareAlike 4.0 International (CC BY-SA 4.0)

Congo’s peatlands are a barrier against climate change

More than a quarter of the carbon stored in the Planet's peatlands is found in the Congo River Basin, says a research released by Nature. But these environments are threatened by land use

Brazil, a law has deprived Indigenous people of 250,000 hectares in two years

In the South American country, a disputed 2020 law paved the way for the acquisition of non-demarcated indigenous lands. Despite legal battles more than two-thirds of Brazilan states are still enforcing the legislation

US Midwest forests have lost 8,000 years of stockpiled biomass

Since the end of the last ice age, forest growth in the west-central United States has contributed to the sequestration of 1.8 billion tons of organic carbon. The accumulated biomass has been destroyed in just 150 years
