poverty. The logistics in which the delivery of humanitarian occurs can be problematic. For example, an earthquake in 2003 in Bam, Iran left tens of thousands of people in need of disaster zone aid. Although aid was flown in rapidly, regional belief systems, cultural backgrounds and even language seemed to have been omitted as a source of concern. Items such as religiously prohibited pork, and non-generic forms of medicine that lacked multilingual instructions came flooding in as relief. An implementation of aid can easily be problematic, causing more problems than it solves. Considering transparency, the amount of aid that is recorded accurately has risen from 42% in 2005 to 48% in 2007. Improving the economic efficiency of aid Currently, donor institutions make proposals for aid packages to recipient countries. The recipient countries then make a plan for how to use the aid based on how much money has been given to them. Alternatively, NGO's receive funding from private sources or the government and then implement plans to address their specific issues. According to Sachs, in the view of some scholars, this system is inherently ineffective. According to Sachs, we should redefine how we think of aid. The first step should be to learn what developing countries hope to accomplish and how much money they need to accomplish those goals. Goals should be made with the Millennium Development Goals in mind for these furnish real metrics for providing basic needs. The "actual transfer of funds must be based on rigorous, country-specific plans that are developed through open and consultative processes, backed by good governance in the recipient countries, as well as careful planning and evaluation." Possibilities are also emerging as some developing countries are experiencing rapid economic growth, they are able to provide their own expertise gained from their recent transition. This knowledge transfer can be seen in donors, such as Brazil, whose $1 billion in aid outstrips that of many traditional donors. Brazil provides most of its aid in the form of technical expertise and knowledge transfers. This has been described by some observers as a 'global model in waiting'. Criticism Statistical studies have produced widely differing assessments of the correlation between aid and economic growth: there is little consensus with some studies find a positive correlation while others find either no correlation or a negative correlation. One consistent finding is that project aid tends to cluster in richer parts
