Population growth at the household level increases pressure on water and land resources. This study examined the impact of household population growth on water and land resource depletion in Limpopo Province of South Africa, using a desktop research approach with secondary data from academic journals, government reports, and relevant policy documents. The findings show that as household population size increases, the demand for water and land also rises, leading to overuse, environmental degradation, soil erosion, pollution, and reduced availability of these resources. The study also found that low use of family planning and contraceptives contributes to faster household growth and unsustainable resource use, threatening ecosystem services and food security. Using the lens of the Second Demographic Transition (SDT) theory, the study highlighted that improving access to family planning and reproductive health education could help manage household population growth and reduce pressure on natural resources. The study concluded that household population growth negatively affected water and land resources in Limpopo Province and recommended promoting family planning programs, sustainable development practices, effective resource management, and stronger local government involvement in planning and policy implementation to ensure environmental sustainability.
