A new zinc-enriched maize variety was released in Colombia on February 23 to help combat malnutrition in South America.
Zinc is an essential mineral that plays an important role in human development, but is not naturally produced by humans. Zinc deficiency can lead to impaired growth and development, respiratory infections, diarrheal disease and a general weakening of the immune system. In Colombia, an average of 22 percent of the population is affected by zinc deficiency. However in certain regions, such as the pacific coast and Amazonia, up to 65 percent of the population is deficient in zinc.

Breeding and seed systems must be adapted to survive projected climate change if major loss of maize yields is to be avoided, a new report shows.
Tools that forecast the response of crops to different weather and climate conditions, coupled with crop yield modeling have enabled agricultural scientists to predict and formulate plans for potential future climate change.
