Social and economic change: development, labour, migration and society
Concepts: migrant labour; the compound system; remittances; the cash economy and hut tax; land alienation and reserves; railways and ports; urbanisation; mission education and Christianity; health and demography; gendered divisions of labour; customs unions; enclave development; inequality; measures of development beyond GDP.
The classic chain: colonial taxation obliged men to earn cash; the quickest route was wage labour on mines and farms; labour migration drew men away from rural households; remittances sustained rural families but increased women's agricultural and household burdens; chiefly authority was both used and undermined by the colonial state. The Witwatersrand gold discoveries (1886) made this a regional system, drawing labour from across southern Africa.
Later change: Botswana's cattle industry, the Lobatse abattoir and the diamond mines from the 1970s transformed state revenue; the Southern African Customs Union (1910) shaped fiscal options; urban growth created new social groups while rural inequality widened.
Traps: equating development with economic growth; treating migration as either wholly free choice or wholly coercion; omitting women and children; assuming change simply replaced tradition rather than reshaping it; ignoring the differences between mine workers, farm labourers, cattle owners and the unemployed.
Rule of thumb: write in three steps - cause, mechanism, consequence - and name who gained and who lost. 'Development for whom?' is a question examiners reward.
Worked example: 'Hut tax changed rural life.' Cause: colonial states needed revenue. Mechanism: tax was payable in cash, not cattle, so men entered wage labour. Consequences: migration, remittances, altered marriage patterns, heavier female workloads, and chiefly dependence on state recognition.
