and more efficient way to deliver aid. Evidence shows that cash can be more transparent, more accountable, more cost effective, help support local markets and economies, and increase financial inclusion and give people more dignity and choice. Sending cash is cheaper as it does not have the same transaction costs as shipping goods. Sending cash is also faster than shipping the goods. In 2009 for sub-Saharan Africa, food bought locally by the WFP cost 34 percent less and arrived 100 days faster than food sent from the United States, where buying food from the United States is required by law. Cash aid also helps local food producers, usually the poorest in their countries, while imported food may damage their livelihoods and risk continuing hunger in the future. Unconditional cash transfers, for example, appear to be an effective intervention for reducing extreme poverty, while at the same time also improving health and education outcomes. The World Food Program (WFP), the biggest non-governmental distributor of food, announced that it will begin distributing cash and vouchers instead of food in some areas, which Josette Sheeran, the WFP's executive director, described as a "revolution" in food aid. Coordination While the number of Non-governmental Organization have increased dramatically over the past few decades, fragmentation in aid policy is an issue. Because of such fragmentation, health workers in several African countries, for example, say they are so busy meeting western delegates that they can only do their proper jobs in the evening. One of the Paris Declaration's priorities is to reduce systems of aid that are "parallel" to local systems. For example, Oxfam reported that, in Mozambique, donors are spending $350 million a year on 3,500 technical consultants, which is enough to hire 400,000 local civil servants, weakening local capacity. Between 2005 and 2007, the number of parallel systems did fall, by about 10% in 33 countries. In order to improve coordination and reduce parallel systems, the Paris Declaration suggests that aid recipient countries lay down a set of national development priorities and that aid donors fit in with those plans. Aid priorities Laurie Garret, author of the article "The Challenge of Global Health" points out that the current aid and resources are being targeted at very specific, high-profile diseases, rather than at general public health. Aid is "stovepiped" towards narrow, short-term goals relating to particular programs or diseases such as increasing the number of people
