Water Case Study

Decent Essays
Water (surface and underground):
Indirect and direct use of water to produce food is the largest consumers of water, requiring one hundred times more than we use for personal needs. During the period 1980–2004 (FAO 2005) the global meat production has been doubled. This growth will continue doubling the meat production in 2000–2050 (Seinfeld and others 2006). Virtual water use for livestock production includes water used in producing food for the castles.
Estimated virtual water requirements for various crops (m³ water/ton)[24]

It is mention worthy that meat-based diets have larger water uses compared to a vegetarian diet. Meat contributes only 37% protein to an average American citizen. If meat is being replaced by an equivalent amount of nutrients from vegan diet such as pulses and nuts will reduce a 30% food-related water footprint of the world.
In fact, 30 to 40 years ago it may have been true 2400, but modern beef production has improved vigorously over time as better husbandry practices with the technology have actually reduced water usage for meat production. Today it takes much less amount of water to produce meat from the cattle. Though the meat production is moving towards the sustainable water use yet the sector is consuming more water compared to the vegetarian food production. Previously water was not considered as a scarce resource. But, today we are considering that the water is a scarce resource. Therefore producing meat with this scarce water is still a challenge. It will be a wise decision to reduce meat production for sustainable development. Much more developed technologies in future may increase the productivity without hampering the water resources.

Biodiversity:
The Food and Agriculture Organization of the United Nations (FAO) reported that the livestock sector is the leading cause of reduction of biodiversity .This survey clearly indicates what
