Reis

The most important food crop in human history, rice feeds over half the world's population and is the staple grain of Asia, Africa, and Latin America. Domesticated from wild Oryza rufipogon approximately 9,000 years ago in the Yangtze River valley of China, rice cultivation has shaped civilizations, landscapes, and ecosystems. Its flooded paddy cultivation creates extensive wetland habitats for migratory birds, amphibians, and aquatic invertebrates while producing significant methane emissions.
