15. 图二显示了联合国发展系统供资的趋势，并分别显示了发展供资和人道主义供资相对于官方发展援助总额的情况。过去 15 年中，联合国发展相关活动的供资增长与官方发展援助增长趋势相似。发展方面业务活动供资的增长速度超过官方发展援助的增长速度，原因是有两个时期，联合国人道主义援助活动的供资有了增长。2008 年，由于燃料和粮食费用上涨，导致全球出现更多粮食不足，进而导致人道主义供资增长。后来，主要由于伊拉克、阿拉伯叙利亚共和国和也门出现危机，人道主义供资再次激增。
15. Figure II shows the trend in funding for the United Nations development system, with development and humanitarian funding also shown separately, relative to total ODA. Over the past 15 years, the growth in funding for United Nations development-related activities followed a similar trend to the growth in total ODA. Funding for operational activities for development increased more rapidly than ODA owing to two periods of increased funding for United Nations humanitarian assistance activities. In 2008, humanitarian funding grew as a result of increased global hunger in the face of rising fuel and food costs. More recently, humanitarian funding surged again owing primarily to the crises in Iraq, the Syrian Arab Republic and Yemen.
