Dairy operations can consume large volumes of water to grow feed, water cows, manage manure and process products. The State of the World’s Land and Water Resources for Food and Agriculture (SOLAW) notes that while the last 50 years witnessed a notable increase in food production, “in too many places, achievements have been associated with management practices that have degraded the land and water systems upon which food production depends.”. Illegal dumping. Water resources face a host of serious threats, all caused primarily by human activity. However, about 97 percent of water found on the earth is salt water and only three percent is fresh water. An increasing body of research now suggests that this is incorrect (2).

"Water Resources: Agricultural and Environmental Issues". Land is the solid surface of the Earth that is not permanently submerged in water. Evidence showed that climate change will have adverse impact on world water resources and food production with high degree of regional variability and scarcity. They are highly adapted to climatic variability and water stress, but also extremely vulnerable to damaging human activities such as deforestation, overgrazing and unsustainable agricultural practices, which cause land degradation. The vast majority of human activity throughout history has occurred in land areas that support agriculture, habitat, and various natural resources.Some life forms, including terrestrial plants and terrestrial animals, have developed from predecessor species that originated in bodies of water. Water resources are used for agricultural, industrial, domestic, recreational, and environmental activities. The diagram below shows that of the world's fresh water, the majority is locked away as ice in the polar ice caps, continental ice sheets and glaciers.

Archaeological evidence suggests a human presence in the area of present-day Culver City since at least 8000 BC. The region was the homeland of the Tongva-Gabrieliño Native Americans. As described in detail in our Data Quality & Definitions section, water withdrawal is defined as the quantity of freshwater taken from groundwater or surface water sources (such as lakes or rivers) for use in agricultural, industrial or domestic purposes. In water-scarce regions and countries, inequity in access to water resources is The Ogallala Aquifer (oh-guh-LAH-lah) is a shallow water table aquifer surrounded by sand, silt, clay, and gravel located beneath the Great Plains in the United States. Yet these natural resources are already under intense pressure from growing population and rising per capita incomes. Surface waters such as rivers and lakes only accounts for less that 1% of the worlds fresh water reserves whereas groundwater accounts for 12% of the worlds freshwater resources. However, even now at seven billion people, an estimat ed 805 million people suffer from chronic hunger. Without the necessary finances to secure land tenure or invest in industrial technology, small farmers have proven incapable of competing against large agri-businesses in globalised food markets. A growing competition for water from different sectors, including industry, agriculture, power generation, domestic use, and the environment, is making it difficult for poor people to access this scarce resource for productive, consumptive and social uses. – globalagriculture.org Kazakhstan petroleum, natural gas, gypsum. phosphates, potash, shale oil.
