Research Paper (undergraduate) from the year 2022 in the subject Organisation and administration - Public safety and order, grade: A, course: Strategic Studies, language: English, abstract: This paper examined the effects of proliferation of small arms and light weapons on national security in Nigeria. It utilized secondary sources of data as well as employed the critical theory to explain the relationship between proliferation of small arms and light weapons and national security in Nigeria. The widespread demand, use and abuse of small arms and light weapons in Nigeria pose serious security and developmental challenges to the country. Some of the implications of this is that Government resources are diverted away from socio-economic and developmental projects to defense and security and human rights abuses which undermine human security are rife. For instance, Nigeria has spent over US$9billion since 2019 trying to curb insecurity this fund would have been channeled into education or health system to boost the welfare of the people.
