Here is how soil bacteria can save crops from salinization

,
An international study has identified soil bacteria that naturally boost plants' resistance to soil salinization stress. The discovery opens up new opportunities for an agriculture that relies less on fertilizers
In the south-western United States, climate change and the build-up of plant matter are fuelling increasingly extreme wildfires. Photo: Eric Coulter, Public Domain Mark 1.0 UniversalEric Coulter, Public Domain Mark 1.0 Universal

In California, the most devastating wildfires are the new normal

Uno studio mostra come il cambiamento climatico e la gestione delle foreste abbiano trasformato la natura prevalente degli incendi. Dal 2012 sono più comuni i roghi ad alta intensità, con conseguenze ambientali ed economiche sempre più gravi

Compostable bioplastic residues do not accumulate in soil

,
An international study fills one of the major scientific knowledge gaps surrounding compostable bioplastics. Any microfragments that may remain after industrial composting do not persist in the soil but continue to biodegrade thanks to microbial activity
Palm oil production in Brazil. Biodiversity loss linked to agriculture is concentrated in tropical areas, which account for almost 80 per cent of the total impact.

Palm, coconut and soybean oil account for 1.5 per cent of global biodiversity loss

, ,
A new study reveals that these three oil crops alone are responsible for around 75% of the biodiversity loss linked to agricultural expansion. A consequence of growing demand for many everyday products
Planting trees on pastures is an effective strategy for protecting biodiversity, but not as much as preserving natural forests. Photo: Onderwijsgek Attribution-ShareAlike 3.0 Unported CC BY-SA 3.0 DeedOnderwijsgek Attribution-ShareAlike 3.0 Unported CC BY-SA 3.0 Deed

Planting trees in pastures increases biodiversity by 44 per cent

,
In developing countries, livestock farming is a means of livelihood for one billion farmers, but the growing need for space for pastures is driving deforestation. A German study suggests how to reconcile economic development and biodiversity

Beyond yields: how drought undermines the nutritional quality of crops

A Canadian study shows that canola, rice and tomatoes reduce iron uptake during drought, leading to a decline in crop nutrient content and potentially affecting global food security

Snow drought is a growing risk for global agriculture

Secondo uno studio internazionale l’impatto diretto dello scioglimento del permafrost sul clima sarebbe regolato da intricati equilibri biologici. Con dinamiche microbiche più complesse del previsto
