“…Arabian Sea is the ultimate disposal site for the effluents and solid waste being carried from the coastal cities like Karachi (IUCN, 2021). There have been various studies vis-à-vis the profiling of the coastal belt of Karachi on the basis of their pollution [31][32][33][34]. The accumulation of single-use plastics, hazardous hospital wastes, nuclear discards, and factories contribute greatly to the coastal pollution [35].…”

“…A study [31] assessed the level of pollution at the ports and fishing harbors of Karachi and found heavy metal contamination in the coastal wasters originating from the port and harbor operations. A similar study [33] found the water analyzed from Lyari River mouth, Fish Harbor, and KPT boat building area highly contaminated with heavy metal pollution.…”

The external influence due to the severe repercussions of unprecedented and un-attended pollution has put vulnerable marine ecosystems at high risk of irreversible damage. This business-as-usual scenario could render them unfit to offer sustenance along with innumerable ecosystem services. Since the Stockholm Conference on Human Environment 1972, there have been global efforts to raise awareness, build capacity, and govern the pollution issue for a sustainable solution. However, there is a growing concern about the adequacy of the desired level of mobilization and readiness so far achieved at the level of various stakeholders to respond to the issue of maritime pollution. In this context, the present study was aimed at assessing the relationship between knowledge, perception, and attitude of the stakeholders regarding their engagement towards maritime pollution at sea, beach, and coastal environments, by incorporating multi-criteria quantitative analysis method for a case study of Karachi area in Pakistan. The structured questionnaire incorporates Knowledge, Perception, and Attitude as three key variables for three principles; four standardized criteria each, with eighteen indicators transformed into queries by applying MCDA’s Simple Multi Attribute Rating (SMART) technique for scoring to quantify the feedback of 304 respondents through a ratio scale having nominal qualifiable classes. The analysis has offered insight into the ways the stakeholders are perpetrating pollution and how their respective actions are important in the abatement of marine pollution. One-tailed Pearson Correlation analysis reveals insignificant relationship between the variables, indicating that the level of understanding of the stakeholders has not developed opinions to an extent that would enable an appropriate behavioral approach toward the abatement of the pollution. It suggests inducing awareness, mobilization, and reforms to encourage collective action by all actors.
