However, people who try to manage these challenges use ＂text type＂ in books and through other communication media （publications）, but the effect has scarcely been effective because, most of the people living in rural communities are illiterates. The purpose of this study was to use pictorial illustrations to create awareness on how socioeconomic development affects rural communities （Cape Three Points） and the extent to which its effect can be seen on human life within the local communities （fishermen, farmers, and fish mongers） in terms of their livelihood, attitudes, education and on the general environment. Interviews were mainly used to ascertain facts on how the situation was before the new developments started. Workshops were also organized for focus groups, through which the effect of pictorial illustrations on the people were ascertained. Again, how they should prepare for the foreseen changes that will emanate from any form of rural development was also discussed. At the end of the study, it came to light that many of our rural areas face significant challenges. These challenges as a matter of fact affect their cultural practices and the socio-economic development of the people in such rural communities and the country as a whole. It is believed that these challenges and many other related concerns that have emanated from this study would be critically recognized and managed if not solved by the powers that be. Results from this study will form a basis for further discussion of socio-economic effects of rural development on rural communities and any other related effects caused by any physical change on rural environment.展开更多
