The second half of the nineteenth century was marked by regular famines and scarcities in India, and famine public works were one of the chief ways for the colonial state to provide relief. Famine public works involved labourers, including a large number of women, working in the construction of railways, roads, canals, and tanks in return for a subsistence wage. The present article contextualizes the practices of famine public works, especially the segregation of famine public works into large departmental and village works, within the intersecting processes of labour, caste, and gender. Drawing on evidence from North Western Provinces and Punjab, the article makes two arguments. First, it shows that segregation in famine works was driven by a shared understanding of the dominant castes and colonial state regarding labour, property, and caste which ensured that village works were reserved for dominant castes. A relational definition of labour was central to the construction of caste respectability on famine works. Second, by comparing the sex ratio of labourers in the two kinds of famine works, the article argues that women's labour was not merely a marker of caste, but constitutive of it.
