Excess nitrogen also impacts soil invertebrates and insects

“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

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

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.

Mosses are an amazing ally for soil health

,
The University of New South Wales study: mosses promote nutrient accumulation in the soil and carbon sequestration. In degraded areas, moreover, these plants accelerate the regeneration process
In Canadian forests, increased tree species diversity produces growth in soil carbon and nitrogen.

Variety of trees promotes carbon and nitrogen sequestration

,
An increase in the number of tree species stimulates greater carbon and nitrogen sequestration, Canadian research explains. But biodiversity is in decline. Promoting it means mitigating climate change and reducing land degradation

Plant roots are crucial for soil animals

,
In tropical soils plant roots affect biodiversity no less than leaf litter, a German research explains. A significant finding for the development of sustainable solutions capable of balancing agriculture and land conservation

Researchers in the U.S. launch five-year soil health survey

,
Four U.S. universities are launching a massive soil analysis project. The initiative aims to counter land degradation which is estimated to cost $67 bn a year in America
