Sustainable Development Goal-Six (SDG-6) Water and Sanitation, Impact on Nigeria, Assessing the Intersection with Public Health and Globalization: A Systematic Literature Review

Aim and scope: The important developmental encounter in the low-income country such as Nigeria has created challenges to make available and sustain the management of safe water and adequate sanitation for the citizenry. The poor access to portable drinking water, and inadequate sanitation practices poses a huge problems in Nigeria predominantly the public health burden linked with the polluted water and its sources, and poor sanitation practices. In this systematic review, the nature and scale of water availability, contamination and transmission of water borne disease and their intersection with public health in Nigeria were explored. The review further evaluated the effectiveness of global community intervention in addressing the anomalies in relation to the Sustainable Development Goals Six (SDG 6)-water and sanitation, and issues hampering the progress in Nigeria towards the target date of 2030. Methods: I searched through the MEDLINE database to select the research articles associated with water availability, water contamination, water quality, sanitation practices, waterborne disease transmission, water (i.e., WASH-Water Sanitation and Hygiene), public health, portable water and sustainability. An analysis of both observational and interventional studies was undertaken. For each study, content analysis was performed to identify the relevant terms such as portable water availability, WASH, disease transmission, public health related outcomes, and to the keydeductions of the study. Results: Strategic themes arising through the search included that about 66.3 million Nigerians lacks access to safe drinking water with no substantial progress in providing portable water for all in Nigeria. Despites various approach by government and other agencies in ensuring water quality and its safety, waterborne disease remains one of the significant public health challenges. Availability of water and the poor sanitation specifically among the rural dwellers are of great importance, being a vital factor in the spread of waterborne disease. The review revealed the common diseases associated with drinking water, and typhoid with the highest occurrence, others are cholera, dracunculiasi, hepatitis and Filariasi. Awareness, adequate funding, infrastructural development and interventions programme are recommended approach to reduce WASH and public health outcomes. Conclusions: Significant water unavailability and poor sanitation practicescumulate as public health burdens, presenting solid evidence that shown water unavailability and sanitation intersecting with public health. Hence, addressing portable water availability and environmental sanitation has a potential of reducing public health diseases with significant impact on SDG achievement.
