Envisioning net-zero food systems

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

A new assessment of over 60 scenarios based on current low-emission practices shows that realizing net-zero food systems will require widescale adoption of new technologies in the next two decades and changes in meat and dairy consumption. A more diverse set of practices and innovative research, including diet shifts and new-horizon technologies, will be needed for this transformation.

Brazil has two populations of American bullfrogs, an exotic species that transmits a deadly fungus

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

Genetic analysis of Aquarana catesbeiana, a species that originally came from North America and is now found in nine Brazilian states, shows that the lineage introduced in 1935 prevails in both captive and feral bullfrogs. Law enforcement to maintain sanitary standards is difficult. The invaders prey on native amphibians and transmit diseases to them .
