First of all, I will explain about WFP (World Food Programme).  

WFP is an international organization for food aid, which was established by resolution of the U.N. General Assembly and the Food and Agricultural Organization (FAO) in 1961.

WFP operates with donations from governments, international organizations, companies and individuals. The sum of the donated money in 2009 was about 4,021 million dollars. The USA was at the top with 1,756 million dollars, and the EU was second with 342 million. Canada was the third and Spain was the fourth. Japan is fifth with 203 million dollars.

Their headquarters is in Rome. The Executive Board oversees WFP's food aid activities.  The Board consists of 36 members, of which 18 are elected by the Economic and Social Council of the U.N. (ECOSOC) and 18 by the Council of FAO.  

Article 2 of the General Regulations of WFP says that the purposes of WFP are:
(a) to use food aid to support economic and social development;
(b) to meet refugee and other emergency and protracted relief food needs;
(c) to promote world food security in accordance with the recommendations of the United Nations and FAO

WFP provided 3.9 million tons of food aid to 102 million people in 78 countries in 2008.

WFP's strategic plan for 2008-2011 lays out five objectives for the organisation:
(1) Save lives and protect livelihoods in emergencies
(2) Prevent acute hunger and invest in disaster preparedness and mitigation measures
(3) Restore and rebuild lives and livelihoods in post-conflict, post-disaster or transition situations
(4) Reduce chronic hunger and undernutrition
(5) Strengthen the capacities of countries to reduce hunger, including through hand-over strategies and local purchase

A protracted crisis disrupts food production and destroys the foundations of people's livelihoods, eroding the social fabric of families and communities. With public institutions often in ruins, people must fend for themselves -- against the odds.
Vital infrastructure such as roads and irrigation systems may need to be completely rebuilt. After a flood or a drought, it can take a year before crops grow again. After conflict, landmines may prevent farmers from working the land. Food assistance can give people breathing space as they set about putting their lives back together again.

WFP's Protracted Relief and Recovery Operations (PRRO) help sustain disaster-hit communities as they re-establish livelihoods and stablise food security.

A PRRO is drawn up when it becomes clear that the 24-month assistance provided under a WFP emergency operation (EMOP) will not be enough.


(3) Development Operations (DEVs)

Away from the headlines of humanitarian disasters, hunger and malnutrition gnaw away at the most valuable asset in any country's development: its people. A person who is always hungry is always poor. For such people, each day is dedicated to finding enough food to subsist. Children hardly ever go to school. Farmers cannot afford to risk trying new agricultural methods.

With no food reserves to protect them from a crop failure and no time to attend a health clinic or learn new skills, these communities live on the edge.

WFP's development aid temporarily frees the poor of the need to provide food for their families, giving them time and resources to invest in lasting assets such as better houses, clinics and schools, new agricultural skills and technology and, ultimately, a better future

(4) Logistics

They transport food to poor countries in the world.
  
(5) Survey of Food Situations and Support Operations

They conduct surveys and analysis on countries and areas that are easily exposed to the risk of famine in order to keep an eye continually on the situation. They also check whether the food reaches the people who actually need aid.
