Security of lives, property and other developmental infrastructures are basic necessities for inauguration of sustainable development policies and programmes. No meaningful developmental ideas, no matter how lofty it is could survive and transcend from mere dreams to concrete reality in a rancorous and chaotic social system which does not promote its capacity to strive. In today’s Nigeria, life has become more precarious and issues of security are dangerously drifting towards complete decay. Unfortunately, despite huge government spending on security in the form of security related votes, the situation has remained unabated as we continue to fear for our lives from kidnappers, political and economic related assassinations, extra judicial killings, religious violence and unwarranted intimidation by agents and or enemies of Government among others. Most of these heinous crimes are perpetuated by youthful population in the country. Restiveness orchestrated by youths has been on the increase in almost all communities in Nigeria, most especially in recent past. Since the inception of our nascent democracy, there has been a proliferation of unravelled violence, killing of innocent people; and, most recently, the insurgency in the North East, militancy in the Niger Delta and marauding attacks by Fulani herdsmen across the country. These ugly episodes of violence have led to incidences of bomb blasts, kidnappings, abductions and many other organised criminalities. Using secondary elaboration technique, this paper attempts to examine the incidence of youth restiveness and its implications for Nigeria’s drive towards sustainable development. The paper argues that poverty, unemployment and lack of access to education, among others, have been responsible for this unprecedented increase of youth restiveness. The study contends that unless this scenario is remedied, sustainable development will continue to be a mirage in the country.
