What makes the Hohokam noteworthy is the development of irrigation works. The earliest... dates from some 2,000 years ago. ...They built dams that redirected the flow of water into irrigation canals, some of them... extending for more than twenty-five miles. ...They built flat-topped pyramids and ball courts, where they used rubber balls imported from Central America. The Hohokam may also have been the first to use the technique of etching with acid in their remarkable designs on marine shells.

He introduced educational reforms and laid the foundation for the Telugu Ganga project to provide drinking water to Madras city, apart from irrigating the dry lands of Rayalaseema.

On Friday noon, July twentieth, 1714, the finest bridge in all Peru broke and precipitated five travellers into the gulf below.

It will be recalled by those who have not allowed their view of modern history to become too hazy, that the close of the twentieth century saw a dream of the engineering world at last realized—the completion of the long-heralded undersea railroad. It will also be recalled that the engineers in charge of this stupendous undertaking were greatly encouraged by the signal success of the first tube under the English Channel, joining England and France by rail.

Water is a pioneer which the settler follows, taking advantage of its improvements.

The obvious result [of the diversion of the Sarasvatī’s waters into the Yamuna system] was the migration of the [Harappan] people towards the north-east where some water was still available in the uppermost reaches of the Sarasvatī and Ghaggar and further east in the upper plains of the Gangā-Yamunā Doāb.’

The northern Cheyennes, after they surrendered to General Miles, irrigated and raised crops at the mouth of the Tongue River for two years, and almost immediately sank into poverty and sloth when given Interior Department rations, for which they did not have to work in order to procure.

As these diggings did not produce the required result, Diogo Fernandez was asked, in 1523, to excavate a third tomb which lay partly under the foundation of a dilapidated building that had been occupied by the Portuguese. He refused at first but was persuaded by the attending priest, Fr. Antonio Gil, who heard his confession and that of the two men, Braz Fernandez and Diogo Lourenco, who would assist him in the pious enterprise. They then began the excavation of a deep and elaborate, and very much empty, tomb. It was Saturday afternoon, and they continued the work into the late evening, when, on the suggestion of Diogo Fernandez, they abandoned their unproductive labours and retired for the night. The excavation was left open and unattended until the next morning, a Sunday, when the men began digging again. It was not long now before the grave disgorged bones that were "much worn out", portions of skull and spine, and a clay pot of earth "bedewed with blood", with a thigh bone in it, and hidden in the red earth an iron Malabar spearhead shaped like an olive leaf, which, after fifteen Christian centuries, still had a piece of wooden shaft miraculously preserved in its socket.

The rivers rose, and, when they receded, sucked more of the fertile soil back down with them, to run down the Pedernales to the Colorado, down the Colorado to the Gulf.

He applied himself with vigour to the development and modernisation of his State and the progress of its people. He is credited with giving shape to the plans for construction of the Nagarjuna Sagar, the Srisailam Project, the Sriram Sagar and the Vamsadhara projects which are, among the most important milestones in the development of this region. If today, Andhra Pradesh is hailed as the granary of South India, much credit is due to him.

In the Indus period the Saraswati river system may have been even more productive than that of the Indus, judging by the density of settlement along its course. In the Bahawalpur region, in the western portion of the river, settlement density far exceeded that elsewhere in the Indus civilization . . . While there are some fifty sites known along the Indus, the Saraswati has almost a thousand . . . [The Yamuna] shifted its course eastward early in the second millennium, eventually reaching its current bed by the first millennium, while the Drishadvati bed retained only a small seasonal flow; this seriously decreased the volume of water carried by the Saraswati. The Sutlej gradually shifted its channel northward, eventually being captured by the Indus drainage . . . The loss of the Sutlej waters caused the Saraswati to be reduced to the series of small seasonal rivers familiar today. Surveys show a major reduction in the number and size of settlements in the Saraswati region during the second millennium.

Harvard biologist Edward O. Wilson warns that China's current program to mitigate huge population increases with gigantic water projects may have dire consequences. Irrigation and other withdrawals have already depleted the , which, starting in 1972, has run bone-dry part of the year in province, where one-fifth of China's wheat and one-seventh of its corn is produced. In 1997, the river stopped flowing for a record 226 days. The groundwater levels of the northern China plains have plummeted. The water table in major grain-producing areas is falling at the rate of five feet a year. Of China's 617 cities, three hundred already face water shortages. Of China's approximately 23,000 miles of major rivers, 80 percent no longer support fish life. The Xiaolangdi dam project now underway along the Yellow River in north China is exceeded in size only by the on the in South China. In addition, the Chinese government intends to siphon water from the Yangtze… and send it over by a canal system to the Yellow River and Beijing, respectively. When it is running, the Yellow River is already one of the most particle-laden in the world. Because of that, it is estimated that the Xiaolangdi dam would silt up within thirty years of completion. The… project is reminiscent of another centrally planned mega-project that ended in grief: the Soviet Union's scheme to drain the to irrigate gigantic cotton farms in Kazakhstan. The project turned one of the world's largest inland bodies of fresh water into [a] salty desert. The potential for calamity in China is therefore huge as it skirts a range of forces presented by the Long Emergency, any one of which, or some combination, could send it reeling over its tipping point: the effects of global climate change, competition for [every resource including] oil, extremes of pollution, disease, and war, either with its neighbors or internally. Despite the current veneer of prosperity and stability, China has tremendous potential for political chaos. As Wilson fearlessly points out, the pressure on China's agriculture and water resources is intensified by the predicament shared by many countries: runaway population growth [caused by industrialization]. Population growth rates may be mitigated… from culture to culture by economic advance (which tends to lower reproductive rates by channeling women into the workplace), but economic development produces other not-so-benign consequences. Developing [systems like] nation[-state]s invariably increase their energy use [as they grow complex]. More cars are used, more electricity [is] generated, [and] more greenhouse emissions [are] sent into the atmosphere. In the Long Emergency, …“there will only be two types of nations: the over-developed and those which will never develop.” China may represent an amalgamation of those two conditions in one nation-state.

The US large-scale surveillance plan failed. It had to be abandoned in 2005. Checks afterwards showed that communications from the terrorists had been collected, but not looked at in time.

Dear to his heart was Lincoln, the Emancipator, an ideal hero whom he consistently revered. Away to the southwest from Kamolondo is a large lake which discharges its waters by the important river, Lomami, into the great Lualaba. To this lake, known as the Chobungo by the natives, Dr. Livingstone gave the name of Lincoln, in memory of him for whom your noble institution was named. This was done because of a vivid impression produced on his mind by hearing a portion of Lincoln’s inauguration speech from an English pulpit, which related to the causes that induced him to issue the Emancipation Proclamation. To the memory of the man whom Livingstone revered he has contributed a monument more durable than brass or stone.
