Wastewater generation in coastal built environments is significantly increasing due to intensifying tourism activities. The dynamics of tourism sector imply environmental pressures resulting in marine biodiversity depletion and unprecedented resource demand. Untreated wastewater discharge in marine protected areas (MPA) is a land-based stressor for marine ecosystems mainly due to emissions of nutrients such as nitrogen (N) and phosphorus (P). Meanwhile, these nutrients can potentially be recovered and reused in the cultivation of crops in (peri-)urban coastal areas to contribute to resource circularity. Lowering nutrients in tourism-based wastewater effluent with the co-benefit of resource recovery is explored to improve MPA resilience.
