Climate change is often cited in the ‘collapse’ of complex societies and linked to agricultural resilience or lack thereof. In this article, the authors consider how demand affected agricultural strategies as farmers navigated the transformations of the Late Harappan phase (c. 1900–1700 BC) of the Indus tradition. Through the modelling of monocropping/multicropping, low/high yield crops, and supply-driven versus flexible production, various economic, environmental and social demands are explored with reference to the choices of farmers and how these decisions differed regionally, and how they impacted the wider Late Harappan de-urbanisation process. The authors’ archaeobotanical perspective on the Indus contributes to wider understanding of how urban societies and their agricultural bases change over time.

This article presents a geomorphological and micromorphological study of the locational context of four Indus civilisation archaeological sites—Alamgirpur, Masudpur I and VII, and Burj—all situated on the Sutlej-Yamuna interfluve in northwest India. The analysis indicates a strong correlation between settlement foundation and particular landscape positions on an extensive alluvial floodplain. Each of the analysed sites was located on sandy levees and/or riverbank deposits associated with former channels. These landscape positions would have situated settlements above the level of seasonal floodwater resulting from the Indian summer monsoon. In addition, the sandy soils on the margins of these elevated landscape positions would have been seasonally replenished with water, silt, clay, and fine organic matter, considerably enhancing their capacity for water retention and fertility and making them particularly suitable for agriculture. These former landscapes are obscured by recent modification and extensive agricultural practices. These geoarchaeological evaluations indicate that there is a hidden landscape context for each Indus settlement. This specific type of interaction between humans and their local context is an important aspect of Indus cultural adaptations to diverse, variable, and changing environments.

The first direct absolute dates for the exploitation of several summer crops by Indus populations are presented here. These include rice, millets and three tropical pulse species at two settlements in the hinterland of the urban site of Rakhigarhi. The dates confirm the role of native summer domesticates in the rise of Indus cities. They demonstrate that, from their earliest phases, a range of crops and variable strategies, including multi-cropping, were used to feed different urban centres. This has important implications for understanding the development of the earliest cities in South Asia, particularly the organisation of labour and provisioning throughout the year.
