Recurring summer and winter droughts from 4.2-3.97 thousand years ago in north India

This highly technical and scientific paper brings together all the recent evidence from Dharamjali Cave in the Himalayas over a 230 year period around 2000 BCE, when the ancient Indus civilization was in decline, to show "that repeated intensely dry periods spanned multiple generations. The record highlights the deficits in winter and summer rainfall during the urban phase of the Indus Civilization, which prompted adaptation through flexible, self- reliant, and drought-resistant agricultural strategies."

The Organization of Indus Unicorn Seal Production. A Multi-faceted Investigation of Technology, Skill, and Style

Although much about Indus seals remains unknown, the steady application of rigorous, detailed analysis of a kind that earlier excavators could hardly dream of is slowly yielding clues and insights into the organization of work and craft in Indus cities.

A Study on Faience Objects in the Ghaggar Plains During Urban and Post-urban Indus Periods

"This research project focuses on the Ghaggar plains, which occupies the north-eastern corner of the Indus society, in order to understand the temporal change of craft production through time from the Indus urban period to the post-urban period in this region. As a part of the project, faience objects have been subjected to a series of scientific analyses to identify their raw materials and production technology" (p. 1) write the authors.

Lakheen-Jo-Daro, an Indus Civilization Settlement at Sukkur in Upper Sindh (Pakistan): A Scrap Copper Hoard and Human Figurine from a Dated Context

We know so little about so many Indus sites, including ones that are buried beneath modern cities and may never be discovered. One such potentially large settlement is Lakheen-Jo-Daro, sometimes also called Lakhan Jo Daro, bits of which have been found in and around the modern city of Sukkur, Sindh, on the Indus River, just across the monumental chert deposits in the Rohri Hills.

Looking beneath the Veneer Thoughts about Environmental and Cultural Diversity in the Indus Civilization

"The recognition of variation and diversity [in the ancient Indus civilization] has encouraged a gradual, though not universally accepted, shift toward the interpretation that certain categories of Indus material acted as ‘a veneer… overlying diverse local and regional cultural expressions'," write the authors.

Indus and Mesopotamian Trade Networks: New Insights from Shell and Carnelian Artifacts

A judicious review of the evidence for trade between the ancient Indus and Mesopotamia, with a focus on prestige objects like carnelian beads and shell bangles and the implications and questions we may draw from them about the nature of the connections between both civilizations.

Semantic scope of Indus inscriptions comprising taxation, trade and craft licensing, commodity control and access control: archaeological and script-internal evidence

The author brings together a great deal of information to argue that "inscribed stamp-seals were primarily used for enforcing certain rules involving taxation, trade/craft control, commodity control and access control," and in relating stamp seals and tablets, that "such tablets were possibly trade/craft/commodity-specific licenses issued to tax-collectors, traders, and artisans," (p. 1).
