There have been all kinds of antipoverty programs launched all over the world, with mixed results. Some approaches fail, while others show minimal results, and some that are promising in the short term don't hold up so well in the long term. The most promising idea today is to give money directly to the poor and let them decide how to best use it. After all, need comes in all flavors.
Of course, massive global antipoverty programs face barriers that make research difficult. Sometimes grants to struggling nations end up in the pockets of corrupt leaders. Funding sources, whether from governments or private foundations, can rise and fall on a whim. An enormous amount of charity funding is dedicated to saving lives in an emergency, such as famine, and aren't designed to address generational poverty. But even when a program is deemed to be ineffective in lifting a significant number of recipients out of poverty permanently, it means the world to the ones who made it out.
