Fruit trees and legumes combined with food crops

Carbon storage: what matters is the input!

After 15 years of climate smart agricultural practices in Madagascar, researchers are categorical: while these alternative methods help increase soil carbon storage, their effectiveness varies substantially. The assessment must therefore be carried out on the scale of the territory.
Wild form of millet in the Sahara

Genetic diversity in millet: a past and future adaptive advantage

Having sequenced the millet genome, an international consortium involving French researchers from IRD, Indian, Chinese researchers and numerous laboratories from the North and South, studied different wild and cultivated varieties. This allowed them to trace the history of cultivated millet and...
Root nodules of Discaria (Order: Rosales), a non-legume species capable of nitrogen-fixing symbiosis.

Nitrogen-fixing symbioses reveal themselves

Recent research has revealed the origin and evolution of symbiotic relationships between certain plants and soil bacteria in order to use atmospheric nitrogen. This knowledge could ultimately contribute to the development of sustainable agriculture minimising the use of chemical fertilisers.
Water run-off on degraded soil and gully erosion due to flooding, in the Mélé Haoussa basin in Niger

New hydroclimatic conditions in the Sahel

The latest figures on soil and climate help explain the enigmatic ups and downs observed in Sahelian hydrology for decades. Knowledge of the mechanisms involved paves the way for practical solutions to adapt agriculture to new environmental conditions.

Cultivating land for carbon

Soils from cultivated areas in tropical regions constitute largely underused carbon sinks. Increasing carbon stocks in soil has become critical to mitigate the effects of climate change but also increase soil fertility. What are the options?
Cowpea roots bear nodules which contain nitrogen-fixing bacteria.

Lipids that boost symbiosis

Certain legumes form a symbiotic relationship with bacteria! Tucked into their roots, these bacteria increase the crop yield of these plants. These bacteria, capable of producing lipid molecules known as hopanoids, therefore seem to provide a distinct advantage.
