Conservation agriculture is stronger than climate change

,
Chinese study shows how conservation agriculture improves productivity under warming conditions by increasing carbon input and stimulating microbial growth

Trees around cultivated fields increase crop yields

,
According to a Canadian study, the presence of trees increases the number of insects that contribute to pollination and the fight against crop pathogens

A warmer Arctic fuels Siberian wildfires

,
Global warming, says a Chinese study, promotes wildfires which, in turn, reduce the frequency of rainfall leading to a vicious cycle

Climate change enhances metal release in coastal areas

,
Events such as rising sea levels, increasing temperatures and changes in precipitation affect metal sequestration conditions in underground estuaries, explains a Swedish study

‘Stop land degradation or we will face health risks,’ say activists ahead of COP29

,
Land degradation poses a global threat to human health, activists recall as the UN Climate Convention in Baku approaches. In the US, 95 per cent of land at risk
Pollution by heavy metals, pesticides, microplastics and nanoplastics causes cardiovascular damage by interacting with protein-bound thiols, inducing oxidative stress and inflammation and altering circadian rhythms.

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
Tropical forests account for more than 50 per cent of the earth's global carbon sink but are threatened by climate change. Photo: Peter Prokosch Attribution-NonCommercial-ShareAlike 2.0 Generic CC BY-NC-SA 2.0 Deed

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
