Traditional Water Harvesting Systems in India: Water resource, though renewable, but is a finite resource and hence limited. Rapid population growth, urbanization and industrialization has exerted pressure on the quantity and quality of both surface and ground water. Agriculture in most parts of the country still depends on the rainfall. Failure of monsoon, thus have serious implications on the economy. Adopting sustainable, effective water conservation measures is one of the key aspects to cope up with the acute water scarcity. As already mentioned that floods and droughts were regular occurrence in ancient India and hence every region has its own water harvesting system that is peculiar with reference to the geographical and socio-cultural features of that region. Water harvesting systems are practiced in India since time immemorial. The history of water management systems goes back to the ancient period. Koutilya was the first economist of the world to define water as an economic commodity too (3rd century B.C). Koutilya was of firm opinion that agriculture could not be dependent solely on the gambling nature of rainfall but on the man-made (irrigation) water. He also advocated the need of people’s participation in water management. Dams were built of stone rubble in 3rd millennium B.C. in Baluchistan and Kutch. During 3000-1500 B.C., the Indus- Sarasvati civilization had several reservoirs to collect rain water. Sringaverapura near Allahabad showed evidences of sophisticated water harvesting system using floodwaters of the Ganges during 1st century B.C .Karikala Chola in 2nd century A.D. built Grand …show more content…

In addition to the river affecting humans, Egyptians learned to control the river’s floods by building irrigation canals and reservoirs, changing the environment to their
(Wiener, 2015) Aqueducts consisted a twin pipe distribution system made with compacted soil and wood so people could get drinkable water from Chapultepec. This water technology had a high availability and low maintenance ; water was carried in one pipe and when it got dirty, it will divert automatically to the other clean pipe so the dirty one could be cleaned or repaired. (n.d.,
Places that have sparse or seasonal rainfall could not sustain agriculture without irrigation. In areas that have irregular precipitation, irrigation improves crop growth and quality. By allowing farmers to grow crops on a consistent schedule, irrigation also creates more reliable food supplies. In document 3 it says "These irrigation systems was the first of their kind and allowed Mesopotamia to grow a surplus of wheat and other crops." this shows why irrigation systems are important and how they impacted the world.
Growing a Surplus Egyptian farmers built walls around fields to trap the Nile’s flood waters. The water soaked in the soil and allowed grains to grow. This form of crop irrigation allowed farmers to produce a food surplus(amount of food greater than the their family’s needs). The Birth of Cities These local rulers used this surplus to buy rich cloth and other goods.
Beer Beer was a key component in the interaction between humans and the environment during the Neolithic period because of its medical benefits. During the Neolithic period, there was no system of purification; thus, the river water used by the respective civilizations are vulnerable to contamination. A lack of clean water led to many waterborne diseases. On the other hand, beer requires boiling water; the process of boiling water killed off the germs and made the water safe to drink.
These rivers caused floods and destruction, yet they deposited fertile soil that allowed these early civilizations to grow crops and survive without traveling great distances to gather food. These states of people had evolved enough to have values and needs beyond that of the basic needs such as food, water, and shelter. These higher values are pretty basic. People wanted to find a meaning in life, to cope with death and the afterlife, and to have justice. Mesopotamians were the first said to have a government, codes of laws, and ethical systems.
In ancient times, you were unable to control the river, so if it flooded, people went along with it. Now Egyptians had the Nile. It flooded annually at about the same time of year, and was very predictable. It covered the land in silt. Ancient Sumerians, however, were located in between the Tigris and Euphrates Rivers.
In urban civilizations, water sources are pumped through a network of pipes into citizen’s homes. Citizens are then required to pay a premium for distribution and usage of the water. Water obtained and distributed by the
Those main rivers share a similarity that all of them flood constantly, which force local peoples to develop better irrigation

Desalination Essay Introduction: Drinking seawater is bad, the salt makes you dehydrated and the more salt water you drink the more it makes you sweat. You also get a dry mouth and low blood pressure as well as your heartbeats faster; you could get bad headaches and a lot of dizziness. Most of the biggest desalination plants are in the middle east like United Arab Emirates, Saudi Arabia, Israel and many more, but the biggest desalination plant in United Arab Emirates it is the biggest power production, in Jebel Ali M-station in Dubai. The plant has an installed capacity of 2,060MW (mega watts) and 140 million imperial gallons of water per day.
Water resources problem areis a serious challenge to the social and economic sustainable development around the whole world. With regards to the predator of fresh water shortage in global scale, Canada also unfortunately falls to its prey. Blessed with abundant fresh water in lakes, streams, rivers and most importantly –the underground water, Canada has long taken it for granted that fresh water supply will never be their concern. However, the approaching of fresh water shortage has only until recently woken Canadians from their dreams. When Alberta Environment and Sustainable Resource Development implemented underground water tapping programs and the Munk School of Global Affairs held a symposium themed on mapping underground water, federal and public concerns are fomenting.

2.1 INTRODUCTION Non-Renewable Resources are resources that have the potential to be used up due to consumption or overuse, they have production, development or replenishment rate that cannot match up with the depletion rate. In short these are resources that can be finished, output exceeds input, and they are infinite. Non-Renewable resources vary from non-renewable fossil fuels like coal, natural gas and oil, non-renewable alternative energy sources like nuclear energy and deep-earth geo-thermal energy, soil, and minerals (Botkin & Keller, 2012). These non-renewable resources range from a few years, up to thousands of years to replenish. The local as well as global challenge, is that most non-renewable resources are directly exploited by humans and their existence is widely threatened were usage
