achieve zero hunger. WFP's Munich-based Innovation Accelerator has sourced and supported more than 60 projects spanning 45 countries. In 2017, WFP launched the Building Blocks programme. It aims to distribute money-for-food assistance to Syrian refugees in Jordan. The project uses blockchain technology to digitize identities and allow refugees to receive food with eye scanning. WFP's low-tech hydroponics kits allow refugees to grow barley that feed livestock in the Sahara desert. Partnerships WFP works with governments, private sector, UN agencies, international finance groups, academia, and more than 1,000 non-governmental organisations. The WFP, the UN Food and Agriculture Organization, and the International Fund for Agricultural Development reaffirmed their joint efforts to end global hunger, particularly amid the impacts of the COVID-19 pandemic, during a joint meeting of their governing bodies in October 2020. In the United States, Washington, D.C.-based 501(c)(3) organization World Food Program USA supports the WFP. The American organisation frequently donates to the WFP, though the two are separate entities for taxation purposes. Reviews Recognition and awards WFP won the 2020 Nobel Peace Prize for its "efforts for combating hunger", its "contribution to creating peace in conflicted-affected areas," and for acting as a driving force in efforts to prevent the use of food as a weapon of war and conflict. Receiving the award, Executive David Beasley called for billionaires to "step up" and help source the US$5 billion WFP needs to save 30 million people from famine. Challenges In 2018, the Center for Global Development ranked WFP last in a study of 40 aid programmes, based on indicators grouped into four themes: maximising efficiency, fostering institutions, reducing burdens, and transparency and learning. These indicators relate to aid effectiveness principles developed at the Paris Declaration on Aid Effectiveness (2005), the Accra Agenda for Action (2008), and the Busan Partnership Agreement (2011). There is wide general debate on the net effectiveness of aid, including unintended consequences such as increasing the duration of conflicts, and increasing corruption. WFP faces difficult decisions on working with some regimes. Some surveys have shown internal culture problems at WFP, including sexual harassment.
