Soil pollution causes the spread of cardiovascular diseases

,
Contamination of soil, water and air causes around 9 million premature deaths per year, a German study says. More than half are of cardiovascular origin

For soil invertebrates, pollution is a worse threat than climate

,
A meta-analysis of more than 600 studies shows that pollution is the most critical factor for the conservation of soil invertebrate biodiversity

Irrigation of rice fields impacts on metal uptake

,
A University of Delaware study highlights the impact of water supply in determining the concentration of arsenic and cadmium in rice plants. But the mechanism is complex and a solution is yet to be found

Heat and drought drive carbon loss in tropical forests

,
A warmer and drier climate will impact the carbon balance of forests in the future, says a US study. The phenomenon will accelerate the loss of the oldest element and reduce the supply of the new one

Soil bacteria survive by cooperating with each other

,
With gene sequencing, researchers at Ohio State University have shown how bacteria cooperate to thrive in environments characterised by different pH levels
In California the rate of erosion after post-fire floods increased between 3.5 and 4.6 times. Photo: Tomwsulcer CC0 1.0 Universal CC0 1.0 DeedTomwsulcer CC0 1.0 Universal CC0 1.0 Deed

In California, fires and subsequent floods accelerate erosion

,
According to a study by the US Geological Survey, erosion on California coasts is closely linked to extreme weather events enhanced by progressive climate change

The price of climate change is getting higher for Africa

,
Climate change impacts Africa's agriculture and food security. High costs and insufficient investment remain the biggest problems, latest report by the UN Development Programme has found
