Loss of urban biodiversity is a threat to human health

,
Loss of microbial biodiversity in degraded soils, which is particularly prevalent in cities, promotes the spread of bacterial pathogens and antibiotic resistance, says an international study. Restoring green spaces, by contrast, creates a biological barrier to their spread

Soil transplanting allows regeneration of degraded lands

,
Transferring a healthy soil mass to a degraded area can ensure rapid restoration, explain researchers at the Netherlands Institute of Ecology. An important finding in the global scenario. But more studies are needed

Dutch researchers bet on bacteria to reduce pesticide use

,
Researchers at the University of Wageningen in the Netherlands will study the potential of bacteria to fight plant pests without damaging the soil ecosystem. Crucial is the action of peptides, biodegradable proteins produced by the microorganisms

Soil damage impacts underground wildlife longer

,
According to a British study, in soil subject to human impact the restoration is slower organisms living underground than in surface. New perspectives in research are needed to protect biodiversity

Herbivores are a surprising ally of climate and soil

,
Far from being destructive, herbivores contribute to climate change mitigation, according to a new research. Their ability to prevent wildfires and return carbon and seeds to the soil is crucial
