IUCN's SDG brochure image - SDG3

Malnutrition affects the development of children and is an underlying contributing factor in about 45% of all child deaths globally. For many rural and coastal populations, wild, local species can provide the essential nutrients needed for good maternal and child health, reducing the morbidity and mortality of young mothers and children. Nature also provides ingredients used for both modern and traditional medicines. Green spaces in urban areas improve mental and physical health and well-being.

IUCN works to conserve local species, ecosystems, protected areas and urban green spaces for the nutrients, medicinal products, clean air and other services they provide.


  • demonstrates the health benefits of locally harvested species used by indigenous and local communities to promote their conservation; 
  • develops guidelines and trains local authorities on designing and managing protected and urban natural areas, with the aim of improving people’s physical and mental well-being.
