How can contemporary poverty be eradicated?

While complete eradication of poverty is a noble ideal, it may not actually be possible. Instead, what most NGOs and governments focus on are methods to reduce the number of people living in absolute poverty. In the years from 1981 to 2013, the number of people living in extreme poverty declined from 41 percent to approximately 10 percent of the world's population.
One of the major factors in this decline (one which may contribute to a continuing decline) is the rise of the GDP of many developing nations, most notably China. The "one child" policy and other forms of economic development have meant that China has made dramatic strides in poverty reduction through economic growth.
Another thing that has a dramatic effect on economic well-being is health. Eradication or control of many diseases has contributed to reduction in poverty. In the developing world, increasing access to healthcare and developing vaccines and treatments for tropical diseases would be quite helpful. The "green revolution" and other increases in agricultural productivity have reduced world hunger. Better infrastructure, including transportation networks and refrigeration, would reduce food insecurity. Increasing equality for women and availability of birth control and maternal health services also contributes to the reduction in global poverty.
Final, social safety nets contribute to poverty reduction, especially when well managed.
