Excess nitrogen also impacts soil invertebrates and insects

A Dutch meta-analysis of 126 studies conducted worldwide illustrates the consequences of nitrogen accumulation for soil microfauna. Effects vary across species. Climate factor

“Colombian government’s fight against deforestation has been a failure,” NGOs say

Operation Artemis, launched by the Colombian government to combat deforestation, has benefited a minimal share of the affected areas, argue NGOs Mongabay and Cuestión Pública. Abuses to indigenous communities have been reported

Canadian researchers start a soil carbon measurement project

An annual project in the state of Saskatchewan will collect data on soil carbon occurrence. The goal is to assess soil effects and generate measurable and verifiable emission credits
The decline in pollinating insects has negative effects on the availability and price of healthy foods such as nuts, legumes, fruit and vegetables, causing an increase in premature deaths. PHOTO: Pixabay

500,000 deaths a year linked to the decline in pollinators

The "prudential" estimate is contained in a new international study published in Environmental Health Perspectives. Premature deaths are thought to be caused by decreasing availability and rising prices of healthful foods, which are in turn linked to the global decline of bee and pollinators
Between 2010 and 2018, commitments made by companies to tackle deforestation in the Brazilian Amazon ensured the protection of about 7,000 square kilometers of forest. But it could have been 24,000.

Cattle-related deforestation in the Amazon could have been halved

If anti-deforestation agreements had been fully implemented, 24 thousand km2 of land could have been saved in the Amazon compared to the 7 thousand actually protected between 2010 and 2018, according to a study from U.S.

Can seed carriers help regenerate the soil?

Created by researchers at Carnegie Mellon University, seed delivery devices pave the way for soil regeneration. But some observers are skeptical
The study of the impact of urbanization on bees and other pollinators was carried out in the Berlin metropolitan area. PHOTO: Fabian Schneidereit on UnsplashFabian Schneidereit su Unsplash

The degree of urbanisation reduces wild bees and butterfly diversity

German research confirms that the degree of overbuilding and the quality of the local habitat influence the activity of bees and other insects. Interactions with plants decrease. Yet urban meadows and pastures, with the right actions, can be precious contexts for pollinators. Starting from a suitable height of the vegetation...

From India to Australia: the bauxite paradox

In India, the mining of bauxite, a rock needed for aluminum production, takes land away from agriculture, producing permanent soil damage. But this same resource, paradoxically, may carry with it a solution
For years the number of insects has been steadily, worryingly decreasing. PHOTO: Pixabay

Insects in decline? “it’s a fault of soil consumption and pollution”

A Swiss-German study investigated the main factors behind the constant decline of insects and their biodiversity. Invasive species and intensive agriculture are also of concern. 40% of all species will be at risk of extinction in the coming decades.
The application of statistical models in combination with spectroscopy makes it possible to assess the concentration of different elements in the soil. Photo: Marco Verch Attribution 2.0 Generic (CC BY 2.0)Marco Verch Attribution 2.0 Generic (CC BY 2.0)

Spectroscopy offers new opportunities for soil analysis

A research from the University of Katowice opens new perspectives in the field of soil analysis. Through spectroscopy, researchers were able to determine the presence and concentration of key elements in soil
