Port of Spain, Trinidad and Tobago: I had the privilege and pleasure to work as a UN Volunteer Medical Doctor in three different countries. My first experience was as a UNV Medical Doctor in Kinshasa, Democratic Republic of the Congo (2009) with the United Nations Organization Mission in the Democratic Republic of the Congo (MONUC). It was an opportunity to learn about the UN mission way of life, and I underwent many trainings. Our level 2 clinic handled numerous Malaria cases besides other medical problems.

Harare, Zimbabwe: When Amy Wickham, an international UN Volunteer, joined the United Nations Children's Fund (UNICEF) in Zimbabwe, she didn't know what to expect. Yet this experience changed her life. "The experience and exposure that I've got since I started as a volunteer has been phenomenal", she says. "The ownership that I've been given over the projects, as well as the time and responsibility that I've been given from professionals that I've worked with has been fantastic."

Prishtina, Kosovo: Building on our achievements with the foresight exercise for unemployment in Kosovo, our innovations team at the United Nations Development Programme (UNDP), which I am part of, is now moving on to the Big Data realm. Every day, people around the world are generating massive amounts of data that, when aggregated and depersonalized to protect the privacy of each one of us, can be used to get insights into the state of society and enable us to respond more effectively and efficiently to its needs.

Katmandu, Nepal: My name is Manash Gadtaula and I am a national UN Volunteer in Nepal. I serve as a civil engineer in a team of eight for the United Nations Development Programme (UNDP) building demolitions project, as a support for the Village Development Committee. Demolition of houses can sound counter-intuitive but it is actually necessary in order to prevent further loss of lives during the aftershocks.

Member States of the Open Working Group on the Post-2015 agenda agreed, "There should be [a sustainable development goal] on peaceful and inclusive societies, with the aim of building effective, accountable, and inclusive institutions at all levels,"  recalled Helen Clark, Administrator of the United Nations Development Programme at the launch of the State of the World's Volunteerism Report 2015.

In the Irkhu Village Development Committee area, a thousand more buildings need to be assessed and potentially torn down within the very first weeks, before the monsoon arrives.

Gaza, State of Palestine: Volunteerism is the path I have chosen to shape the development of my community and my own self-confidence. In my home of Gaza city, within the State of Palestine, volunteerism, as with many other things, takes its own particular shape. We volunteer to help people and to help ourselves in the context of high levels of poverty and unemployment.

Port-au-Prince, Haiti: My name is Francesca Pinna, I am a United Nations Volunteer in the United Nations Development Programme (UNDP) Country Office in Haiti. I never thought that I would get engaged in the field of Disaster Risk Reduction (DRR). It happened by chance after the earthquake that hit the Italian city of Aquila in 2009. I understood what an unexpected natural disaster could really provoke and how much destruction could have been avoided through an adequate knowledge of disaster risks and appropriate preparedness.

New Delhi, India: In his celebrated work The Prophet author, poet and artist, Khalil Gibran, wrote, “You give but little when you give of your possessions. It is when you give of yourself that you truly give.”
