A new phase of Afghanistan project is about to begin. It is believed that in the post- 2014 period, the country is going to face at least three major challenges: security, political and economic. On the basis of recent experience, and I would like to explore of presidential elections role for UN as well as regional players. In reconstruction, more than seventy nations have committed their resources and significant gains have been made in areas like education, infrastructure, health care, women empowerment etc. In a situation of declining western interest and resources, I would also like to suggest ways in which achieved gains are maintained through effective implementation of limited projects. I will discuss other issues, the protection of human rights, Support for peace and reconciliation efforts, elections, humanitarian support and counter-narcotics as the major areas of the world body’s work in Afghanistan. This cooperation between the United Nations system and Afghanistan goes many decades back. This is not just the last eleven years of UNAMA, and although not without challenges and not without questions and not without problems, this kind of cooperation brought a lot of positive experience in this interaction between the UN system and Afghanistan. In particular, political and security uncertainties undermine business confidence. It has also been estimated that the planned foreign troop withdrawal by the end of 2014 will directly lower annual growth by two or three percentage points, as a result of reduced local spending by these forces and by the concurrent withdrawal of foreign civilian organizations with international and national staff. In addition, while traditional donors such as the European Union have provisionally committed to supporting Afghanistan beyond 2014, they have made it clear that aid will be conditional on improvements in governance and a reduction in corruption, which few analysts believe can realistically be achieved. The background of my paper seeks to find out the problems and prospects of peace in Afghanistan United nation’s role in it challenges, and way forward.
