Social protection is emerging as a critical tool in the drive to eradicate hunger, yet the vast majority of the world's rural poor are yet to be covered.

Programmes proliferate but vast majority of rural poor remain uncovered by social protection

Such programmes currently benefit 2.1 billion people in developing countries in various ways -- including keeping 150 million people out of extreme poverty.

Expanding such programs in rural areas and linking them to inclusive agricultural growth policies would rapidly reduce the number of poor people, the report says.

The report was released on the eve of World Food Day (16 October), whose focus is on social protection's role in breaking the cycle of rural poverty.

"It is urgent that we act to support the most vulnerable people in order to free the world of hunger," said FAO Director-General José Graziano da Silva.

"Social protection programs allow households to access more food -- often by increasing what they grow themselves -- and also make their diets more diverse and healthier. These programs can have positive impacts on infant and maternal nutrition, reduce child labor and raise school attendance, all of which increase productivity," he said.

Breaking out of the hunger trap

Only about a third of the world's poorest people are covered by any form of social protection. Coverage rates dip even lower in South Asia and sub-Saharan Africa, regions with the highest incidence of extreme poverty, the report said.

Without such assistance, many poor and vulnerable people will never have the opportunity to break out of the poverty trap -- in which hunger, illness and lack of education perpetuate poverty for future generations, according to the report.

Most countries -- even the poorest -- can afford some kind of social protection program. FAO estimates that globally, some $67 billion a year in income supplements, mostly provided by social protection programs, would -- along with other targeted pro-poor investments in agriculture -- allow for the eradication of hunger by 2030. That is less than 0.10 percent of world GDP.

Understanding social protection

Currently many extremely poor households are forced to sell off productive assets, put children to work, over-exploit their small landholdings unsustainably, or settle for badly paid jobs.

Yet basic social transfer schemes offer the poor an opportunity to improve their own productive potential. They also have positive spillover effects on local economies, increasing business opportunities, raising rural wages, and allowing the poorest to acquire or invest in assets.

In Zambia for example, a pilot cash-grants program led recipient households to greatly increase livestock ownership as well as land under cultivation, input use and ownership of tools such as hoes, sickles and axes, leading to a 50 percent jump in the overall value of locally produced agricultural commodities.

Beneficiaries also spent more on food, clothing and health-and-hygiene - an amount 25 percent greater than the value of the initial transfer. The wider community also benefited through the increased demand for locally produced goods and services generated by the transfer-every dollar transferred generates an additional 79 cents in income, often for non-beneficiaries providing these goods and services.

At least 145 countries today provide one or more forms of social assistance, including unconditional cash transfers, meaning outright grants for eligible recipients, conditional cash transfers, usually linked to school attendance or health checkups and, public-works programs that offer guaranteed employment. Other forms include in-kind transfers, including food distribution and school feeding programs.

Cash means more than spending

The report stresses that the notion that social protection reduces people's work effort is a myth. Rather, recipients often respond to social protection positively, including improving the nutrition and education of their children, relying more on home production rather than poorly paid wage work and also increasing their participation in existing networks such as funeral societies, a common form of risk management in many traditional communities.

Social protection schemes can also be transformative over time. One well-designed Bangladeshi programme gave poor rural women livestock and other productive assets, as well as a monthly stipend to cover the period until recipients were able to earn additional incomes.

The FAO report also cites other successful examples of social protection programs in Ethiopia, Ghana and Lesotho.

Such findings show how social protection is an investment, rather than a cost. It is also clearly illustrated by Brazil's Bolsa Família, a well-integrated scheme that reaches a quarter of the country's population and costs only 0.5 percent of GDP.

Still, the report stresses how social protection alone cannot sustainably eradicate hunger and rural poverty. It therefore underscores the importance of combining and coordinating public investment in social protection with public and private investments in the productive sectors of agriculture and rural development. Such actions will ensure inclusive economic growth as a sustainable way to break the cycle of rural poverty.
