Identifying pre-Hispanic water storages in agricultural areas of south-central Andes through diatom evidence

In the Andes, there are several pre-Hispanic irrigation networks with structures destined for water storage. However, it has not been widely discussed in archaeological research. This is probably due to their being difficult to identify. The aim of this study is to explore the use of diatom assemblage analysis as a methodological tool suitable to help in the identification and characterization of these ancient hydraulic structures. We analyzed two archaeological structures interpreted as water reservoirs from north-western Argentina (EH1 in Antofagasta de la Sierra and U-88R1 in Yocavil) and compared them to current reservoirs. The diatom species composition and the changes in the dominant ecological groups in the studied structures highlight different periods of hydraulic behavior. EH1 contained and stored water, but there were periods of time in which there was a lack of use or abandonment of the structure. However, the U88-R1 structure does not have diatom evidence of containing standing water for a prolonged time but presence of wet soils. Thus, the structure could have been used for other water management strategies. The results show that diatom analysis is a methodological tool with a high potential to study ancestral hydrotechnologies.     

The Agnotology of Eviction in South Lebanon's Palestinian Gatherings: How Institutional Ambiguity and Deliberate Ignorance Shape Sensitive Spaces

A significant part of Lebanon's Palestinian refugees live in unofficial camps, so‐called “gatherings”, where they reside on Lebanese land. Many of these gatherings are now threatened with eviction. By means of two qualitative case studies this article explores responses to such eviction threats. Residents, it turns out, engage in deliberate disinformation and stalling tactics and invoke both a professed and real ignorance about their situation. In contrast to dominant discourses that project Palestinian refugees as illicit and sovereignty undermining, I explain these tactics as a reaction to, and duplication of, a “politics of uncertainty” implemented by Lebanese authorities. Drawing on agnotology theory, and reconsidering the gatherings as sensitive spaces subjected to aleatory governance, I propose that residents’ responses to the looming evictions are a manifestation of the deliberate institutional ambiguity that Lebanese authorities impose on the gatherings. As such, the article contributes to understanding the spatial dimensions of strategically imposed ignorance.
