Dutch drinking water

David Zetland and Bene Colenbrander recently posted "The Evolution of the Dutch Drinking Water Sector". The abstract:
Dutch drinking water companies (DWCs) have brought more water of better quality to more people over the past 160 years, but their institutional environment has changed with social priorities. We divide these changes into four eras in which an initial solution leads to a new constraint that forces a change in priorities and thus DWC actions. The first era begins around 1850 when polluted common pool water attracts sellers of drinking water as a private good. Priorities changed around 1900 as the government pushed for a network expansion that would bring drinking water services to all as a public good. The third era began around 1950 as strains on common-pool budgets and water supplies shifted the focus to rationalization and efficiency. The fourth and current era began around 1970 with DWCs being asked to restore ecosystems and play a larger role in the community. These shifts demonstrate how the path towards clean, safe drinking water may twist and turn as new opportunities eclipse past successes and changing priorities shift the relative costs and benefits of different actions.

Digital library IV: Bartolus's Tractatus de fluminibus seu Tyberiadis

Image
After beginning the digital library of historical environmental law with works from the last few hundred years, we go back in time this week to the fourteenth century and the  Tractatus de fluminibus seu Tyberiadis  (1355,  1576 edition (source of the images in this post) here ) of the great medieval Italian jurist Bartolus of Saxoferrato. As Bartolus explained at the beginning of the work, he was inspired to write the book while on vacation near Perugia, despite his attempts to enjoy his vacation and stay away from legal scholarship: This river [Tiber]... circles that splendid mountain on which the city of Perugia is situated and while flowing a great distance through its district, the river itself is bordered by plains, hills and similar places. These places are also well inhabited, enhanced with many beautiful buildings and luscious orchards bearing lots of fruit. Thus, when I was resting from my lecturing and in order to relax, was travelling towards a certain villa situated near ...

The earliest boundary water treaty

Figure 1:  Memorial cone of the Mesilim Treaty Thanks to Peter Sand for contributing this post! [Footnotes after the jump.] The Musée du Louvre in Paris holds tangible evidence of the world’s first known legal agreement on boundary water resources: viz., the Mesilim Treaty , concluded in the 25th century B.C. between the two Mesopotamian states of Lagash and Umma . The terms of the treaty have been preserved as cuneiform inscriptions on a limestone cone (figure 1) and a stele commemorating Lagash’s victorious battle enforcing the treaty.[1] Fragments of both artifacts were excavated in 1878-1912 by French archeologists on sites at Tellō ( Tall Lawh, Dhi Qar Governate in Southern Iraq), the ancient temple-city of Girsu, once the capital of Lagash.[2] The inscriptions, transcribed and translated into French, German, Italian and English,[3] turned out to match several other texts on corresponding archeological finds of the period. The key exhibit, the so-called ‘Stele of the Vultures’, d...

Today's "This Day in Water History" has this: Judson Harmon, c. 1912 June 11, 1895: First day of tenure of Judson Harmon as U.S. Attorney General. “Harmon issued the most explicit statement of what became known as the American doctrine of absolute sovereignty, that “the rules, principles and precedents of international law impose no liability or obligation upon the United States,” in a case involving a claim by Mexico for damages from diverting the waters of the Rio Grande.” Or, as one source put it: “US Attorney General Judson Harmon tells Mexico that the US will ‘do whatever it pleases’ with water from the Rio Grande.” Commentary: Even for those days, this was a pretty amazing statement.
