Bentiu, South Sudan: From my time as a United Nations Volunteer with the United Nations Mission in South Sudan (UNMISS), I will always remember waking up to the sounds of gunshots and heavy mortar shelling on Monday the 16th of December 2013. An uneventful weekend had been followed by one of the most chaotic and frightening times in my life.

Mananjary, Madagascar: In the district of Mananjary in south-eastern Madagascar, an ancestral practice exists which involves abandoning twin babies. Thanks to the intervention of the United Nations System (the United Nations Development Programme, the United Nations Children’s Fund and the World Food Programme) over several years, many voices have been able to advocate the abolition of this tradition, which violates the fundamental rights of children.

Addis Ababa, Ethiopia: As a UN Youth Volunteer, I have been assigned to the United Nations Environment Programme's (UNEP) liaison office in Addis Ababa, Ethiopia, and my assignment here is slowly coming to an end. My role as an Environmental Outreach Specialist includes increasing UNEP's visibility, environmental awareness and communication, as well as acting as a liaison with the Ministry of Environmental Protection and Forestry.

Kigali, Rwanda: In cooperation with 22 other African countries, the One UN in Rwanda held consultations in order to formulate a nationally owned post-2015 development agenda. The objective of the consultations was to stimulate an inclusive, bottom-up debate on the post-2015 development agenda. The idea was thus to facilitate a visioning process, which is based on people’s experiences and ideas for the future of the world they want to live in.

Zanzibar, Tanzania: As a UN Volunteer working with the United Nations Population Fund (UNFPA) in Zanzibar, I am involved in activities on sexual and reproductive health, working closely with government institutions. Looking for new innovative methods to raise the awareness of young people is one of the things I have been working on during my assignment with the United Nations Volunteers (UNV) programme. Theatre is a good way to raise awareness of women-related issues.

Wau, South Sudan: Everybody likes a story with a happy ending. This is especially true for people working on the disarmament, demobilization and reintegration (DDR) of ex-combatants and women associated with armed forces and groups (WAAF). As a Management Systems Officer, Prince Isaiah, a UN Volunteer from Liberia, accumulates data on people’s reintegration for the Crisis Prevention Recovery Unit of UNDP’s DDR program in South Sudan. For him, finding success stories is one of the best parts of his job.

Kigali, Rwanda: Every child has the right to play! (Art.31 of the United Nations Convention on the Rights of the Child.) It seems so obvious; yet there are more than seven hundred million children who have never known what play means. That is about a quarter of all the world's children!

Nairobi, Kenya:  It has been a long, tiring and dusty journey across north eastern Kenya on a mission to witness first-hand the effects of the drought that has left millions on the brink of starvation. With me on this trip is UNICEF Sweden Goodwill Ambassador Liza Marklund and Swedish photographer Martin von Krogh. Together we have travelled from Dadaab, the world’s largest refugee camp, to Liboi near the Kenya-Somalia border and their journey ends in Wajir, a drought stricken district in northern Kenya. But for me this journey is far from over.

Kampala, Uganda:  'Unite for children' is what UNICEF stands for and what drives UN Volunteers to support UNICEF’s work.

Kampala, Uganda: I started volunteering at UNICEF Kampala in September 2010, after working for twelve years for a charity organisation in Uganda which works with vulnerable groups (women, children and people with disabilities) to overcome poverty and malnutrition in sustainable ways. As a new volunteer, I had great expectations and was full of ambition. I looked forward to meeting and working with new people at UNICEF, gaining new skills and using my experience to contribute to making a positive difference in the lives of women and children in Uganda.
