UN Day was celebrated on 23 October 2009, at the UN House in Windhoek, Namibia. The day was marked with an introduction by the United Nations Resident Coordinator, Ms. Kari Egge, “Why do we commemorate UN Day?”, followed by a moment of silence in remembrance of Dr. Setu Kaba, late UNAIDS Country Coordinator and the UN colleagues who lost their lives in the line of duty.

UN staff members were encouraged to wear something blue on the occasion to pay tribute to the UN. The fun however started when staff had to introduce themselves, engaging in a quiz and prize giving moment whereby the staff’s knowledge had been tested by the UN Resident Coordinator and the UNHCR Representative.

As of 21 September 2009, 20,837 people have signed the UN-led Seal the Deal campaign petition that was aimed to canvas political will and public support for reaching a comprehensive global climate agreement in December.

One million signatures were needed for the petition, which was presented by the civil society to the governments of the world at the UN Climate Change Summit in Copenhagen in about 100 days time.

Scientists had warned that climate impacts were accelerating, and the world needed political leadership at the highest level to ensure the people and the planet were protected and the 21st Century economy powered by green growth.

In support of the Climate Change week, the UN Resident Coordinator and the Director of the United Nations Information Centre (UNIC) in Windhoek encouraged all UN staff in Namibia to wear green on 22 September 2009 and to sign the online Climate Change Petition.

United Nations Information Centre (UNIC) in Windhoek organized a day of cultural performance at the Windhoek International Youth Centre on Wednesday, 12 August 2009, to commemorate International Youth Day.
Ms. Anthea Basson, National Information Officer of UNIC Windhoek delivered the Secretary General's message at this occasion.

The young men and women of Namibia were encouraged to adopt a global sense of responsibility under the theme of this year’s International Youth Day – “Sustainability: Our Challenge. Our Future” – a global call to action for young men and women.
According to 2007 statistics, youth comprised 25 per cent of the world’s working age population yet accounted for 40 per cent of the unemployed.  The global economic recession meant that, in the near future, youth unemployment would continue to climb. 
“Without a doubt, young people have proven themselves to be key partners in sustainable development.  They have gotten involved in international forums such as the Commission on Sustainable Development, and have helped their Governments and communities to formulate poverty reduction strategies, entrepreneurial schemes and many other policies and initiatives”, the Secretary General's message said.
To commemorate this day, youth organizations in Namibia engaged in workshops and cultural performances.
