IntroductionEnvironmental preservation has become a critical issue for the survival of the world's habitat (Oladumiye, Ogunlade and Omole, 2017). Yet, environments in third world countries like Nigeria still suffer major degradations which endanger sustainability (Odji, 2019). Increased generation and improper disposal of municipal solid wastes is a major cause of environmental degradation. However, with proper environmental awareness creation, activities which endanger the sustainability of the environment may be alleviated.Interestingly, media may be efficient in passing information and orientating members of the public on basic environmental maintenance. With the use of media, visual communication has proven to be more effective through different platforms such as television, internet, books, poster and several others to communicate to viewers. Comic-style illustration as an aspect of visual communication, emerged as a means of communicating to people on these various platform.Visual communication has been found to be superior to verbal communication when communicating environmental issues due to its ability of providing information pertaining to different occurrences when one cannot be physically present (Zeynep, 2015). Furthermore, the emergence of technology has enhanced learning process and the role of visual communication as a learning aid cannot be exempted considering the fact that it improves learning and stimulates thinking (Michael, Rosanalia and Allen 2014).Visual communication as a learning aid in the educational sector remains significant as Noha (2017) identified visual aids as an important tool for assimilating complex subject matters. Thus, identifying the ability of media to improve interaction, participation among students.However, the Nigerian population is a mixed multitude made up of both educated and grossly uneducated people who may find it very difficult to read, old and young, having careful or nonchalant attitudes towards the environment. Therefore, an effective means, which will appeal to such mixed multitude, is required.People are known to relate more with realist images as human perception of things comes from the visual observation of their surroundings (Zeynep, 2015). Although, learning has not only been useful in classroom but has also been effective among the people with little or no classroom experience. In Madagascar, Tobias (2016) findings using comic style illustration to educate farmers showed effective, as learning was made easier and language barrier was reduced. Therefore, this paper proposes graphical, comic-style, illustrations as a tool for the creation of awareness on improper waste disposal as a means of promoting environmental sustainability.

This paper asserts that public awareness creation and raising (ACR) adopting local-visual-evidences (LVE) have already been established by studies as an effective health communication strategy that can be employed to alleviate the outbreaks of communicable diseases. The purpose of the paper is to establish the major challenges of effective implementation of this important risk communication strategy. This study was informed by relevant good practice, lessons learned, and the results of previous studies on awareness creation (AC) with a focus on communicable diseases in Nigeria. This review examined the probable prospects and challenges of adopting LVE-based AC contents to provide policymakers, public health, and safety agencies accessible information for effective decision-making options. The preliminary findings revealed that the use of LVE-based AC information services or contents is not favourable for the patients, their families, or friends when appropriate precautions are not taken. The same also applies to the government, public awareness communication campaigners or content designers, and their development partners or sponsors. However, the paper found that LVE-based public awareness communication campaigns would be effective in curbing the outbreaks of communicable diseases if effectively conducted at the community level. It is highly recommended that public awareness communication practitioners, governmental and non-governmental organisations, involved in communicable disease management and prevention, know that participatory community engagement leads to higher awareness for behaviour change. The study proposed a LVE Adoption Pattern to guide decision-makers in crisis situations.
