How does water scarcity affect agriculture and food security?
Water scarcity has a major impact on agriculture and food security. The more water-scarce an area is, the more likely it will be to have problems with food security. In agricultural areas, water scarcity leads to decreased crop yields. As a result of decreasing crop yields, there is a decrease in the amount of food available for consumption.
What are the effects of industrial agriculture on drinking water?
Thus, families that rely upon private drinking water wells are especially vulnerable to the harmful effects of water pollution from factory farms and other forms of industrial agriculture and must test their own drinking water to avoid health problems. 54

Defining the Agricultural Water Problem. Water is increasingly becoming scarce and the failure to use freshwater appropriately poses serious risks to sustainable development. Despite its limited supply, there is a widespread tendency to misuse water.
What are the effects of Agriculture on the environment?
Agriculture intensification is often accompanied by increased soil erosion, salinity and sediment loads in water and by the excessive use (or misuse) of agricultural inputs (e.g. fertilizers) to increase productivity. Pollution caused by agriculture can contaminate water, food, fodder, farms, the natural environment and the atmosphere.
How does electricity affect agriculture?
Agriculture uses energy directly as fuel or electricity to operate machinery and equipment, to heat or cool buildings, and for lighting on the farm, and indirectly in the fertilizers and chemicals produced off the farm.
What happens when water gets electrified?
Electrocution in water poses a serious and deadly danger to everyone who swims in a lake or a pool. It occurs when faulty wiring or poorly maintained equipment releases an electrical current into the water which enters people’s bodies, paralyzing their muscles and causing them to drown.
What causes electric shock in water?
The main cause of electric shock drownings is faulty electrical wiring on boats or piers that causes electric current to leak into the water. Electric shock drownings occur most often in fresh water, which is conductive due to dissolved minerals and impurities.
What are three common causes of electrical accidents in agriculture?
The most common cause of electrocutions are portable grain augers, oversized wagons, large combines, and other tall equipment that come into contact with overhead power lines. Every year 62 farm workers are electrocuted in the United States.
Does electricity dissipate in water?
Uman says lightning is high in voltage and in current, but when lightning strikes water the charge dissipates rapidly away from the strike point because it spreads equally in all directions through the water rather than following channels of best conductivity as it does on land.
How are water and electricity related?
Energy and water are intricately connected. All sources of energy (including electricity) require water in their production processes: the extraction of raw materials, cooling in thermal processes, in cleaning processes, cultivation of crops for biofuels, and powering turbines.
What is electrified water?
EO water is created when a saltwater solution goes through an electrolysis process, which separates the water’s positive and negative ions. This makes two forms of water: one very acidic and one very alkaline.
Is the danger of electrocution greater in seawater or in freshwater?
The ocean’s salt makes the water 500 times more conductive than fresh water, so that the electrical current can likely pass through without focusing on the swimmer compared to fresh water. It doesn’t take very much electrical current to hurt an unsuspecting swimmer.
How do you know if water is electrified?
Shock Alert will notify you of electricity present in water. If it beeps and flashes red, DO NOT SWIM. If it flashes green, no voltage is detected. Due to the tragic nature of these injuries and deaths, Shock Alert was created to detect the presence of electrical voltage in water.

What Are the Sources of Water Pollution from Agriculture?
6 Livestock and poultry on the largest CAFOs generated 369 million tons of waste in 2012. 7 Animal waste is stored either in pits or in open ponds, called lagoons. Such waste-containment areas often leak and, during large storms, can rupture. 89 To dispose of the waste, CAFOs spray this manure onto farm fields. The environmental damage from spraying and from leaking, ruptured lagoons can be devastating. Surface and groundwater contamination (serious threats to aquatic ecosystems) and excessive nitrates in drinking water (serious threats to public health) stem from CAFO pollution. 10 11 Animal waste can also include pharmaceutical residues, heavy metals (like copper and zinc) and harmful bacteria , which can leach into water supplies. 121314
What happens when fertilizer leaches into the groundwater?
