The Great Green Wall, for the benefit of environments and rural societies in the Sahelo-Saharan zone

The Great Green Wall is an unprecedented project designed to mitigate the effects of climate change and combat land degradation and poverty in the Sahelo-Saharan zone. The project represents much more than a simple reforestation initiative on the edge of the desert. It mobilizes scientists...

Can we defeat malaria?

After seventy years of commitment and some very significant results since the early 21st century, the combat against malaria has reached a crossroads. Progress has slowed down in recent years, but new research tools, strategies and avenues have come to light. In addition, global health stakeholders...

Water management, a sustainable development issue

As the source of all life, water is essential to our health, well-being and dignity as well as to the functioning of our ecosystems and societies. Access to water is therefore synonymous with development. However, around the world, water is being overexploited, wasted, and contaminated at...

Out of the 8.4 million migrants in West Africa, less than 10% of them travel to Europe. Local migration, whether between cities and rural areas, intra-regional or...

Genetic variation in chickpeas revealed

An international team of researchers has studied the genome of 3,366 chickpea varieties from different parts of the world. Their work provided a clearer picture of the chickpea’s evolutionary history and the effects of domestication on the genome, while also highlighting interesting genetic...

Safou fruit reveals dynamic urban genetic diversity

Disturbances linked to human activity - overexploitation, deforestation, climate change etc. - are all threats to the genetic diversity of plants. However, city dwellers with cultivated gardens can play a key role in protecting species. A multidisciplinary study combining genetics and ethnoecology...

Covid-19, women take the lead

In India, Senegal and Brazil, women in lockdown are involved in solidarity initiatives. Preparing and distributing meals, transporting medicines to the most vulnerable, making and donating masks, they mobilized throughout the health crisis by managing to adapt to the restriction measures.

Development: the place of gender

At school, in their family relationships, in hospital or in court, women in the Global South face inequalities on a daily basis. Despite the significant progress observed in the areas of education, healthcare and legislation, they are fewer in number than boys in universities and salaried employment...

Uganda may hold the key to the future of robusta coffee!

Hit by climate change, coffee production is seriously under threat. To combat this risk, international teams, including the IRD team led by Valérie Poncet, went in search of wild coffee plants such as robusta in the forests of Uganda. They thus identified previously unknown and drought-resistant...

Religious Reconfiguration in the Global South

Challenging the simplistic stereotype of a binary geopolitical and religious landscape, defined by the inevitable opposition between the Muslim South and the Christian North, the academic work conducted by IRD and its partners reveals a much more nuanced situation. Their research has explored the...
