Abstract

The Living Deltas Hub is a UKRI GCRF-funded community investigating the environmental, societal, and natural-cultural heritage of three South and Southeast Asian mega-deltas; the Ganges-Brahmaputra-Meghna delta spanning India and Bangladesh, and the Mekong Delta and Red River Delta of Vietnam. Globally, deltas occupy only 1% of the total land area, but support the livelihoods of ~500 million citizens. As a consequence of growing human populations and intensified anthropogenic activity these deltas face multiple challenges, such as eustatic sea level rise, land subsidence, saline intrusion, unsustainable extraction of natural resources, habitat loss, pollution, and are currently on a trajectory towards collapse. The waterscape of the deltas place SDG 6 (clean water and sanitation) at the heart of sustainable development. Thus, the Hub aims to quantify and assess human impacts on the water quality of major river channels, canals, and ponds by establishing catchment-wide water quality monitoring supplemented by historical data, biomonitoring networks, community science projects (including water quality and participatory GIS) and local knowledge of water quality. This will result in improved understanding of the impacts of the multi-functionality of water sources in Asian mega-deltas from basic domestic use (bathing and drinking water) up to industrial scale aquaculture, and can lead to the success of SDG 6 (clean water), SDG 3 (good health and wellbeing), SDG 2 (zero hunger – here, through sustainable aquaculture), and SDG 14 (life below water). In addition, the combined methodology of water quality monitoring and understanding lived experiences can be used to identify the concerns of local communities, identify inequalities in the access to safe water (working towards SDG 10 reduced inequalities) and understand the female experience (working towards SDG 5 gender inequality). Using a literature review of pond water quality and use in the delta regions and data from household surveys conducted in three regions of the Mekong Delta (Ben Tre, An Giang and Can Tho), we will use ponds as a case study to demonstrate how this approach can be used to improve understanding of community access to safe water.
