“…The demographic and socioeconomic conditions in the study area are common in several developing countries and Latin America. In these countries, as in the study area, water scarcity is expected due to the growing water demand and the lack of collection and treatment infrastructure [25].…”

Assessment of the Water Footprint in Low-Income Urban Neighborhoods from Developing Countries: Case Study Fátima (Gamarra, Colombia)

The increasing pressure on water resources due to population growth and high water consumption, especially in urban areas from tropical developing countries, has led to a rise in water stress. The sustainability analysis of the Total Water Footprint (WFtotal) and the Environmental Sustainability Index (SIblue) are holistic water management tools that allow for establishing pressures over water resources. This study assessed the WFtotal and their components (Blue, Green, and Gray) in the households of a low-income tropical neighborhood in Colombia with sanitation deficiencies. The activities associated with intra-household water use and higher environmental impact were identified, considering socioeconomic conditions and the water quality in the receiving water body, a wetland, through the application of surveys in a sample of households. The results showed that 86.7% of the WF was the WFgreen, followed by the WFgray (13.2%), and finally, the WFblue (0.2%). The high value of the WFgreen was related to food consumption patterns, which varied according to socioeconomic level. Likewise, the SIblue shows that the Baquero wetland presented scarcity scenarios regarding water quality and sedimentation, threatening the environmental service provision from this strategic ecosystem. Finally, tools such as the WFtotal and SIblue help identify strategies that could be implemented to reduce the pressure on the water resources and the water quality degradation in ecosystems relevant to global sustainability as wetlands.

“…In developing countries, particularly in rural areas, where over 80% of small family farms reside, the absence of proper water infrastructure significantly contributes to poverty and food insecurity [4]. These regions, vital for global food production, are hindered by inadequate water and sanitation services, exacerbating socioeconomic disparities [5]. Improving water quality and availability in rural areas is critical for enhancing living conditions and economic development [6].…”

Despite the recognized efficiency of natural coagulants, their widespread adoption in the water treatment industry remains low. Our study evaluates the effectiveness of three natural coagulants—Moringa Oleifera, Yausa (Abutilon Insigne Planch), and Breadfruit (Artocarpus Altilis)—in reducing water turbidity levels of 40–50 NTU. Among these, two are native plant species potentially applicable in rural Colombian areas, where there are evident disparities in water infrastructure. This research contributes to the development of these coagulants, exploring their integration with existing water treatment methods, determining their optimal concentrations, and efficiencies in turbidity removal. Our findings reveal significant turbidity removal efficiencies: 88.9% for Moringa Oleifera, 83.3% for Yausa, and 67.2% for Breadfruit. These results indicate the feasibility of these agents as sustainable replacements for traditional chemical coagulants, exhibiting a level of effectiveness alike to that observed in Moringa Oleifera. However, challenges in practical implementation and sustainability, covering technical, environmental, economic, and social aspects, are notable obstacles. The aim of this study is to not only demonstrate the effectiveness of these natural coagulants but also to encourage their broader acceptance and integration into sustainable water treatment practices incorporating two unstudied plant species, such as Yausa and Breadfruit, furthering research to overcome existing challenges.
