On the occasion of Human Rights Day, the Alkarama Foundation presented its 7th annual award for Human Rights Defenders in the Arab World on 8 December 2015 to Omani human rights advocate and former parliamentarian, Talib Al Mamari, in recognition of his important work defending human rights in his country, in particular since the crackdown on civil society that followed the 2011 protests. The ceremony held at the Ecumenical Centre in Geneva commended Al Mamari's courage speaking up for his countrymen before Parliament and standing with them against the arbitrariness of the government's policies, especially those related to the health of the citizens of his native region of Liwa.

On 25 November 2015, human rights defender Said Ali Said Jadad was arrested once more for "using the internet to disseminate material that would prejudice public order" after his sentence of one year in prison was upheld by the Salalah Court of Appeal on 18 November 2015. Known for his criticism of the Omani authorities' systematic repression of peaceful dissent, Said Jadad has been the victim of numerous acts of reprisals. In view of the facts and of his inability to obtain redress in his country, on 2 December 2015, Alkarama sent an urgent follow up to the United Nations Special Rapporteur on the rights to Freedom of Peaceful Assembly and of Association (SR FPAA), Maina Kiai, in the hope that he can help put an end to the constant harassment suffered by Jadad.

On 10 November 2015, the Working Group on the Universal Periodic Review (UPR) adopted a draft report containing the recommendations made by United Nations Member States to Oman during the State's review, which took place on 5 November 2015. During the review, States expressed their concern over the human rights' situation in Oman, especially regarding violations of the rights of peaceful assembly and freedom of expression, the Nationality Code and the lack of ratification of international human rights instruments by the country, issues previously raised by Alkarama in its report submitted to the UN Human Rights Council (HRC) in view of Oman's review on 23 March 2015.

On 9 October 2015, UPR Info held the pre-session meeting on Oman in view of the State's second review under the United Nations Universal Periodic Review (UPR), which will take place during the UPR's 23rd session in November. During the pre-session, Alkarama, together with Child Rights Connect (CRC), Global Campaign for Equal Nationality Rights (GCENR) and Human Rights Watch (HRW), as well as the National Human Rights Commission of Oman (NHRC) − the Omani national human rights institution − expressed their concerns regarding the human rights situation in Oman to several delegations of UN member States, which will make recommendations to Oman during its review. The main issues raised by Alkarama focused on reprisals against political activists and human rights defenders, excessive use of force against protesters, criminalisation of freedom of expression and the Nationality Code.
