Implementation of development projects at the district and sub-district level has been frequently marred by lack of coordination, knowledge of local conditions, and sound planning on the side of international donors as well as by corruption and inefficiency on the side of Afghan government officials. On the provincial and national level, projects such as the National Solidarity Programme, inter-provincial road construction, and the US-led revamping of rural health services have met with more success. As NATO prepares to withdraw the majority of remaining ISAF troops by the end of 2014, whether the Afghan government will be able to sustain the developmental gains made over the past 12 years, and to what extent international civilian aid organizations will be able to continue operations or refocus their efforts based on lessons learned, remains to be seen.
