Sustainable yield: the maximum quantity of water calculated over long-term conditions in the basin, including any temporary excess that can be withdrawn over a year without an undesirable result; Sustainable groundwater management: the management and use of groundwater that can be maintained without causing an undesirable result.
The Ogallala Aquifer (oh-gə-LAH-lə) is a shallow water table aquifer surrounded by sand, silt, clay, and gravel located beneath the Great Plains in the United States. As one of the world's largest aquifers, it underlies an area of approximately 174,000 sq mi (450,000 km 2) in portions of eight states (South Dakota, Nebraska, Wyoming, Colorado, Kansas, Oklahoma, New Mexico, and Texas).

Sustainable agriculture is farming in sustainable ways meeting society's present food and textile needs, without compromising the ability for current or future generations to meet their needs. [1] It can be based on an understanding of ecosystem services .
When more groundwater is pumped from wells than replenished, storage of water in the aquifer is being mined, and the use of that water is no longer sustainable. As levels fail, it becomes more difficult to extract water, and pumps will struggle to maintain the design flow rate, which may consume more energy per unit of water.
In coastal regions, over pumping groundwater can increase saltwater intrusion which results in the contamination of groundwater water supply. [10] Sustainable use of groundwater is essential in water conservation. A fundamental component to water conservation strategy is communication and education outreach of different water programs.

Without access to clean water, nearly every industry would suffer, most notably agriculture. As water scarcity grows as a global concern, food security is also brought into consideration. A recent example of this could be the drought in California; for every $100 spent on foods from this state, a consumer is projected to pay up to $15 ...
Use of groundwater, especially for irrigation, may also lower the water tables. Groundwater recharge is an important process for sustainable groundwater management, since the volume-rate abstracted from an aquifer in the long term should be less than or equal to the volume-rate that is recharged.
Water resources are natural resources of water that are potentially useful for humans, for example as a source of drinking water supply or irrigation water. These resources can be either freshwater from natural sources, or water produced artificially from other sources, such as from reclaimed water or desalinated water (). 97% of the water on Earth is salt water and only three percent is fresh ...
