Through PIF^2's social impact mobile game platform, users are playing it forward for charity

Water:Charity assumed that money and celebrity exposure would be able to solve the world’s access-to-clean-water crisis. But this approach often led to more abandoned water pumps. Charities – and journalists who cover them – are now working to concentrate on making their solutions sustainable.

Some problems are simply too complex to solve with any single approach. The “collective impact” strategy of creating alliances of civic and business leaders is being applied to social problems across the nation.

Nongovernmental groups – especially ones that depend on donations – hate to fail, and never make their failures public. But at new conferences, social activists share and learn from failure.

In Jakarta’s slums, families can’t buy their children nutritious food. So Mercy Corps started a for-profit chain of food carts selling healthy kids’ meals. A second column highlights the challenges NGOs face when they try to start for-profit businesses.

The philanthropic practice of buy-one-give-one can be ineffective if communities are given ill-fitting donations or if the donations supplant local markets. The company Warby Parker ensures lasting change by financing the means of local production of a pair of glasses for every pair bought.

In Oakland, a company created an online crowdfunding platform that allows users to earn interest by financing clean energy projects and gives people with good social intentions a direct line of action. Across the world, there is a growing movement toward people-powered clean energy.

Americans often want to connect to a cause beyond writing a check. Crowdsourcing is creating new forms of philanthropy globally, giving donors more choice and a stronger connection to the projects they fund.

Very few people go to city council meetings. MindMixer, a tech startup company, increased civic participation in states across the U.S. with online platforms for city officials and the community to discuss ideas.

New crowdfunding options can help even the smallest donor's contributions to have a meaningful impact, bolstering a sense of personal involvement, maximizing knowledge about causes, and inspiring greater participation.

For most well-meaning donors, it can be difficult to calculate which charities are most effective with their funding - that is those that aim to solve the most serious problems, use interventions that work, employ cost-effective strategies, are competent and honest, and can make good use of each additional dollar. Organizations like GiveWell are part of a new and welcome trend toward rigorous evaluation of social change programs, and helps people best decide where to donate based on what causes matter to them most.
