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

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
Contaminated land in Verdun, northern France. The effects of soil contamination in World War I battlefields are still clear more than a century later. This a precedent that scares Ukraine and global agriculture. Photo: public domainpublic domain

Ukraine will have to deal with war damages to agriculture for a century (at least)

,
Ukraine farmland could suffer the same consequences as the soils of northern France, which are still contaminated with the munitions waste from World War I. A severe problem for the global food supply chain

China will provide an updated soil survey by 2025

,
Forty years after the last study, Beijing aims to complete its land census. While waiting for the data, however, the scenario looks grim. Pollution, erosion and fertility loss remain the main problems
Protected areas in Brazil amount to 220 million hectares, or 51 percent of the Amazon. Extending protection over another 130 million hectares would cost no more than $2.8 billion a year. Photo: Andre Deak Attribution 2.0 Generic (CC BY 2.0)Andre Deak Attribution 2.0 Generic (CC BY 2.0)

Protecting the Amazon would require minimal spending, a study says

,
In the Brazilian Amazon, costs per hectare of anti-deforestation policies are hundreds of times lower than in protected areas in Europe. But government commitment remains largely weak

Europe under fire as rubber industry is destroying African forests

,
In 21st century, the development of rubber tree plantations has led to the destruction of more than 500 km2 of native forests in Africa, says Global Witness. EU regulation is still weak

Land degradation is threatening wetlands in Lesotho

,
About one-third of wetlands in Lesotho show soil degradation. A FAO-sponsored study releases first useful information to start restoration efforts

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

New sewage management brings benefits to soil, EEA says

,
A decentralized sewage treatment offers better opportunities for the development of circular solutions even for arable land, a European Environment Agency analysis says
