Fluctuating Currents: Balancing urban growth and restoring native riverine synergies in Mumbai — the case of Dahisar River

In 1690 CE, a transformation was initiated by the British East India Company on the seven islands along India's western coast. These islands, once primarily Portuguese territories featuring indigenous communities deeply intertwined with rich ecological and cultural histories spanning millennia, underwent a gradual metamorphosis into the major metropolis known as 'Bombay,' a trajectory that persists today in its rebranded identity as 'Mumbai.' This article delves into how the commonly accepted imaginations of urban utopia progressively turned away from the perceived stagnant waters of rivers and estuaries that, in reality, served as vital coastal ecological buffers. The expansion of Mumbai city propelled its citizens, particularly marginalised low-income groups and traditional settlement inhabitants, towards the outskirts where vestiges of natural ecosystems endure. This shift granted them rudimentary necessities such as water and outdoor spaces, including prospects for agriculture. The convergence of socially vulnerable communities with ecologically delicate zones frequently led to heightened intricacies and debilitation, placing immense stress on both the city's ecological and social resources. This article centres on the examination of urban rivers, using the Dahisar River, a representative seasonal watercourse in Mumbai, as a focal point. Through this exploration, it seeks to scrutinise the multifaceted networks intertwined with Mumbai's river systems, emphasising the urgency of recalibrating perceptions of rivers in Indian urban landscapes. The study also reflects upon the tumultuous socio-political dynamics of the city, involving governing bodies, indigenous stewards, urban residents, and industries. Amid the array of potential solutions, technical and ecological facets often take a backseat to the socio-political determination required to adopt a more ecologically conscious stance. Nonetheless, optimism persists, as climate change mitigation and urban well-being emerge as entrepreneurial prospects for the nation's economic hub. The national leadership aims to position itself as a catalyst for change, aligning with global ecological narratives on the political stage.
