Ethiopia has some of the lowest gender equality performance indicators in sub-Saharan Africa. Although the Constitution and the National Policy on Women afford Ethiopian women equality before the law, in practice, women continue to face obstacles from discriminatory traditions and extreme poverty. The long periods of armed conflict inside and outside its borders have contributed to poverty and displacement of many women. Ethiopia has also been engaged in counter-insurgency operations against the Ogaden National Liberation Front in Ethiopia's Somali region (known as Ogaden) since 1994. Ethiopia ratified the Convention on the Elimination of All Forms of Discrimination Against Women (CEDAW) on 10th September 1981 and is ranked 115 out of 144 listed countries on the 2017 Global Gender Gap Index (GGI). In regards to disarmament, Ethiopia voted for the adoption of the Arms Trade Treaty, but has not yet signed or ratified. In 2017, $487,800,000 was spent by Ethiopia on its military. Women activists in Ethiopia continue to fight for women's rights and protection against sexual violence amidst political and social repression.
