The study of gender and gender related issues in development studies have emerged as contemporary issues and important trends in virtually all disciplines ranging from arts, humanities to sciences and technology. The attention shown in these areas by the proponents have profoundly affected gender roles in various aspects of human endeavors ranging from governance and politics, commerce and industry, education, law, science and technology etc. It is important to note that these concepts are becoming a central feature of all the disciplines thereby making them multidisciplinary in scope as they help in shaping our lives, our attitudes, and our behavior in the larger societies for our day to day survival and livelihoods. In Nigeria, efforts of several governmental and non-governmental agencies towards ensuring gender equity in the society through various programmes, initiatives and engagements with the wider public are very significant in the last few years. These are done in line with the Millennium Development Goals (MDGs) which set out in summary to eradicate hunger, poverty and provide access to good health care. This paper takes a cursory look at the concepts of gender, gender equity/equality, concepts and model of sustainable livelihoods and the MDG's, initiatives and engagement programmes of governments on gender equity and development issues in Nigeria; and the complementary roles of information and grassroots mobilisation towards overall national development. Recommendations and suggestions are made to ensure that the concept of a "weaker sex" and undue disparities in status and role expectations are eliminated from our psyche in all that we do. Appropriate strategies to improve information network and grassroots mobilization among the people irrespective of status and age in our various communities are also included. It is through these and many others that the true meaning of sustainable livelihoods can be achieved for both sexes.
