Episode Overview

Title: Jason Cons, "Delta Futures: Time, Territory, and Capture on a Climate Frontier" (U California Press, 2025)
Air Date: February 23, 2026
Host: Yadong Li
Guest: Jason Cons, Associate Professor of Anthropology, University of Texas at Austin

In this episode, host Yadong Li interviews anthropologist Jason Cons about his latest book, Delta Futures: Time, Territory, and Capture on a Climate Frontier. The conversation explores how the Bengal Delta is shaped as a “climate frontier,” where overlapping crises, development projects, and contesting future imaginaries converge on an ecologically vulnerable terrain. Cons discusses his research trajectory, the analytic utility of the concept “frontier,” the materiality of “siltscapes,” and the lived realities for delta inhabitants amidst rapid ecological and politico-economic change.

Key Discussion Points & Insights

1. Jason Cons’ Scholarly Trajectory and Entry into the Delta

• Background: Cons started with interests in South Asian borders and partition legacies, which led to his first book Sensitive Space about enclaves on the India-Bangladesh border.
• Shift to Climate: During fieldwork in the 2000s, he noticed global climate politics recasting local border issues as global climate security challenges, especially regarding the India-Bangladesh border fence.
• Pull to the Delta: Engagement with the Malambus Movement and work with Nijera Kori and Kasha Paprocki on shrimp aquaculture’s social impacts drew him to the region (02:17–05:01).

Notable Quote:
“I was constantly running into people who had shown up in Bangladesh because they were interested in the ways the India-Bangladesh border was the climate border...which was not how I understood it at the time. But it intrigued my interest as an ethnographer to think more about how those politics were transposed into questions around climate.” — Jason Cons (02:49)

2. Genesis and Evolution of ‘Delta Futures’

• Organic Process: The book’s direction wasn’t pre-conceived—initially focused on classic development ethnography, it evolved as on-the-ground realities revealed a more complex and layered picture (05:38–08:29).
• Conservation, Development, Security: Research encountered puzzles—how conservation efforts increased local precarity; industrialization (e.g., Mongla Port growth); and shifting border imaginaries.

Notable Quote:
“The project kind of emerged out of me thinking it was going to be this constrained thing and then just being constantly confused by things that I was running across ethnographically.” — Jason Cons (08:19)

3. Frontier as Analytic and Ethnographic Lens

• Multiple Scales:
  • The Bengal Delta, historically a site of recurring, layered frontiers—settlement, agrarian, export production (e.g., shrimp).
  • Analytically, "frontier" allows attention to the recursive and dynamic nature of space, shaped by diverse actors and materialities.
• Climate Frontier Concept:
  • Not everything in the delta is driven only by climate change, but the anticipation of climatic futures becomes central to new logics of extraction, development, and opportunity (09:23–13:03).

Notable Quote:
“I call the Bengal Delta a climate frontier, not because everything is narrowly related to climate change within it, but rather that...expropriation and opportunity are increasingly organized around imagination and anticipations of a future of climate change.” — Jason Cons (12:15)

4. Temporality, Competing Futures, and Incommensurability

• Temporal Nature of Frontiers:
  • Frontiers are always “in motion” and future-oriented; projects on the delta are justified by, and shape, visions of what’s to come.
• Contradictory Projects:
  • Industrialization vs. conservation; migration management for anticipated “climate refugees” vs. export processing zones.
• Key Tension:
  • These competing futures often cannot coexist—raising questions about conflict, priorities, and lived consequences (13:53–18:02).

Notable Quote:
“Temporality ends up being just a way for me to try and think through...the incommensurability of different visions for what the future looks like in the Bengal Delta...some of these futures can’t actually come to be in the same place at the same time.”—Jason Cons (16:20)

5. ‘Siltscape’: Reimagining Land, Territory, and Property

• Material Instability:
  • The delta is defined by silt—a material always in flux, shaping and unmaking both land and water.
• Siltscape vs. Landscape:
  • "Landscape" is inadequate; “siltscape” captures the constant instability and recursive building/erosion processes (18:50–23:05).
• Planning Challenges:
  • Administrative boundaries, infrastructure, and property models struggle to match the shifting, recalcitrant terrain.

Notable Quote:
“Silt is inherently a form of matter that’s in transition...it’s the very thing on which people build their futures.” — Jason Cons (19:12)

6. Recalcitrance and Failure of Technocratic Control

• Historical Roots:
  • Colonial and postcolonial projects tried to fix land and water to facilitate taxation and extraction, but the delta refused such fixes.
• Embankments and Shrimp:
  • Embankments, initially to keep water out and facilitate rice cultivation, were repurposed for shrimp ponds (needing water kept in) with unintended ecological consequences and increased vulnerability to cyclones (23:42–28:06).

Notable Quote:
“There’s kind of a wonderful collision of vernacular ways of engaging with silt and silt’s refusal to stay fixed in place...” — Jason Cons (24:36)

7. Ecologies of Capture

• Multiple Forms:
  • “Capture” describes not only species (crab, shrimp) but territory, revenue, and bodies—both by local actors and the state.
• Banditry and Policing:
  • Conservation policies and new paramilitary policing units fragmented traditional systems, unpredictably increasing kidnappings as fishermen could no longer “pay protection” in advance (28:47–34:16).
• Broader extraction logics:
  • Both legitimate and illegitimate forms of resource capture overlap and are linked to broader processes of dispossession and adaptation.

Notable Quote:
“The more I started to explore that question, the more I realized...the problem of dacoity in the Sundarbans...was just one telling piece of a much larger set of questions about the capture and management of territory, rents, and resources.” — Jason Cons (32:44)

8. Methodological Approach: “Ethnography of the Delta”

• Multi-sited, Mobile Fieldwork:
  • Cons moved among villages, embankments, industrial zones, and bureaucratic spaces, recognizing that the “object” of study was the drifting delta itself.
• Analytic Challenge:
  • Connecting disparate processes happening across sectors—industrialization, conservation, piracy, local initiatives—was more an issue of writing than research design (34:16–37:35).

Notable Quote:
“It really ended up feeling like I wasn’t doing an ethnography in the Delta, I was doing an ethnography of the Delta.” — Jason Cons (35:36)

9. Grounded Resilience & Development Interventions

• Critical of “Resilience”:
  • The NGO/state narrative often shifts risk onto delta residents, asking them to “be resilient” with little support—sometimes leading to “bizarre interventions.”
• Alternative Practices:
  • Local collectives intermixing indigenous and engineered seeds, building communal seed banks, or advocating for infrastructure more attuned to actual weather patterns.
• NGOs Like Nijera Kori:
  • Focus less on service provision, more on pressing for policy inclusion and rights (38:28–43:21).

Notable Quote:
“I think that people who live in the Delta actually do have really robust, and also speculative...ideas about what a resilient future could look like...profoundly rooted in people’s lives and in the Delta siltscape itself.” — Jason Cons (39:55)

10. Current and Future Projects

• Editorial Work:
  • Reviving the journal Limn, exploring themes like ‘climate’s interiors’—how climate is experienced within bodies, buildings, and everyday life.
• Research:
  • Studying frontiers and species management in Texas (with a focus on feral hogs), and humanitarian forecasting projects (43:49–46:37).

Notable Quotes & Memorable Moments
