UNITED NATIONS - The UN General Assembly approved Wednesday an almost 17 percent increase in the current United Nations budget for the 2008/2009 period to $ 4.87 billion from $ 4.17b, including nearly $ 500m for the next six months for peacekeeping operations in Sudan's war-ravaged Darfur region. The measure was among a host of resolutions adopted by the assembly as it wrapped up its work for this year, mainly covering internal administration and disciplinary issues, deterring procurement fraud and malfeasance within the world organisation and improving transparency. "Let us use the holidays to recharge our batteries and return in 2009 with renewed vigour," Assembly President Miguel D'Escoto said inclosing the session. We cannot afford to rest on our laurels after this intensive period. Indeed, we have a busy schedule ahead and there are many important issues that call for dedication and diligence from all of us." Budgetary measures adopted ranged from an assessment of about 449.86 million dollars for the first six months of 2009 for the African Union-UN Hybrid Operation in Darfur, the provision of 429.5 million dollars for 27 special political missions, the establishment of several posts for the Rule of Law Unit, and 5 million dollars for design work for the integrated compound in Baghdad for the UN Assistance Mission for Iraq. On internal administration, the GA approved a major shift from the current system of contracts, which the assembly said "lacks transparency and is complex to administer," and the GA adopted new contractual arrangements consisting of temporary, fixed-term and continuing appointments, to come into effect under a single set of Staff Rules, effective July 1, 2009. The assembly requested UN Secretary-General Ban Ki-moon to ensure a judicious mix of career and fixed-term appointments, to achieve an appropriate balance between institutional memory, long-term commitment and independence and the ability to bring in fresh insights and expertise, and to dismiss non-performing staff. On the administration of justice within the world body, the GA adopted the statutes of the UN Dispute and Appeals Tribunals, as of July 1, emphasising that all possible use should be made of the informal system of justice in order to avoid unnecessary litigation. The regular budget of the United Nations is approved by the General Assembly for a two-year period. The main source of funds for the budget is the contributions of member states.
