Lessons learned in Burkina Faso can contribute to a new decade of forest restoration

The Alliance of Bioversity International and the International Center for Tropical Agriculture
Peer-Reviewed Publication

In 2018, the West African nation decided to restore 5 million hectares of degraded land by 2030. New research shows what works - and what doesn't - when restoration coincides with degraded landscapes, pressure on natural resources and climate change.

Deforestation favors an increase in the diversity of antibiotic-resistant soil bacteria

Fundação de Amparo à Pesquisa do Estado de São Paulo
Peer-Reviewed Publication

Study suggests that replacing native vegetation with pasture or crops increases competition among microorganisms, favoring those with antimicrobial resistance genes. Brazilian scientists advocate more research to find out whether bacteria can migrate to food and reach human.

Bacterial competition in situations of food scarcity prevents survival of mutants

Fundação de Amparo à Pesquisa do Estado de São Paulo
Peer-Reviewed Publication

Study compares the phenomenon observed in the species E. coli to a "tragedy of the commons", in which individual interests take precedence over the collective good. According to the authors, it masks the emergence of bacterial variants and makes the colony's mutation rate appear lower.
