The fall armyworm in Africa: a new insect pest in corn crops

In Kenya, the survey of pest insects in corn crops has revealed that a recently-arrived pest, Spodoptera frugiperda, has not replaced existing pests. The various species of pests are co-inhabiting in fields and calling into question the pest control strategies currently in use to preserve the yields...

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...

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...
