Empirical environmental law scholarship

Robert Fischman and Lydia Barbash-Riley recently posted "Empirical Environmental Law Scholarship". Beyond taking a look at the recent history of environmental law scholarship, the article is interesting for our purposes both for its view on what constitutes empirical scholarship and for its argument about the connection between descriptive and prescriptive work. The abstract:
The most important development in legal scholarship over the past quarter century has been the rise of empirical research. Drawing upon the traditions of legal realism and the law and economics movement, a variety of social science techniques have delivered fresh perspectives and punctured false claims. But environmental law has been slow to adopt empirical tools, and our findings indicate that it lags behind other fields. There are several clear benefits from an empirical agenda to explore how to make environmental law more effective. But no previous article has applied the lessons from empirical scholarship in other fields to environmental law. This Article fills that gap by assessing the state of environmental empirical scholarship, evaluating the strengths and weaknesses of published approaches to answering empirical questions, and recommending methods to advance the empirical research agenda.
Where environmental law scholarship has employed empiricism, it has done so mostly in the pollution control area. More empirical environmental law research relies on analysis of existing data than on the generation of new data, and experimental treatments are completely absent from our review of the literature. One strength of the empirical work in environmental law is analyzing existing data to determine correlations using regression analysis and statistics. But empirical environmental law scholarship underperforms in offering policy prescriptions. This assessment of the field identifies several methods and sources of data that may prove useful in advancing and sharpening empiricism’s contribution to law reform and implementation.

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.
