Hunting in the Ghaznavid State: Courtly Culture, Military Practices and Political Power
History, EarlyView.Abstract Hunting occupied an important place in the royal court culture of the Ghaznavid state (963–1186 CE). Ghaznavid hunting culture developed through the interaction of Turkic‐Islamic political traditions, Persianate models of kingship and local ecological settings. Rather than constituting a fully formalized institution, Ghaznavid hunting practice

AGRICULTURE IN A SOCIALIST CITY: Towards an Alter‐Urban Political Ecology
International Journal of Urban and Regional Research, EarlyView.Abstract Urban political ecology has developed as a critique of capitalist urbanization. This article develops the concept of alter‐urban political ecology to define urban environments emerging not from capitalist urbanization but from efforts to transform it. Drawing on archival research and ethnographic fieldwork in five urban farms in socialist Cuba,
