A multiple breadbasket failure is the simultaneous disruption of grain production in several major agricultural regions globally, primarily due to acute climate events. This phenomenon has gained increasing attention [clarification needed] in climate risk assessment and food security studies, particularly as climate change threatens to increase its likelihood in coming decades, potentially ...
In the South American Andes, farmers have used terraces, known as andenes, for over a thousand years to farm potatoes, maize, and other native crops. Terraced farming was developed by the Wari culture and other peoples of the south-central Andes before 1000 AD, centuries before they were used by the Inca , who adopted them.
Also amphidrome and tidal node. A geographical location where there is little or no tide, i.e. where the tidal amplitude is zero or nearly zero because the height of sea level does not change appreciably over time (meaning there is no high tide or low tide), and around which a tidal crest circulates once per tidal period (approximately every 12 hours). Tidal amplitude increases, though not ...
(pl.) aboiteaux A sluice or conduit built beneath a coastal dike, with a hinged gate or a one-way valve that closes during high tide, preventing salt water from flowing into the sluice and flooding the land behind the dike, but remains open during low tide, allowing fresh water precipitation and irrigation runoff to drain from the land into the sea; or a method of land reclamation which relies ...

Mean sea level is commonly defined as the midpoint between the mean low and mean high tides at a particular location. [6] sea stack See stack. seabed. Also sea floor or ocean floor. The bottom of a sea or ocean. As with land terrain, the ocean floor may have ridges, mountains, valleys, and plains. seaboard
However, these general definitions have little utility for those implementing food relief as "region", "widespread", etc. are undefined. One of the earliest methods of measurement was the Indian Famine Codes developed by the colonial British in the 1880s. The Famine Codes defined three levels of food insecurity: near-scarcity, scarcity, and famine.
The water, energy and food security nexus according to the Food And Agriculture Organisation of the United Nations (FAO), means that water security, energy security and food security are very much linked to one another, meaning that the actions in any one particular area often can have effects in one or both of the other areas.
