The real test of any successful G8 summit is not a communiqué peppered with promises, but whether its commitments are kept. Many of us think the G8's leaders should be doing more at Camp David, but the least they can do is to finish what they have started.
The decisions made by world leaders on what to cut and what should be funded have real-life implications for millions of people who live beyond the reach of hospitals and clinics in developing countries.
We're at risk of failing the poorest nations if we don't step up our efforts to address a health concern that's connected to the success of nearly every important socio-economic development milestone. I'm talking about neglected tropical diseases.

The 2012 G8 summit offers an important moment for global leaders to signal to the rest of the world that immunization and vaccine development programs are a top priority. They should not let this opportunity pass them by.
We can fight back against this lethal cocktail of climate change and extreme poverty. In fact, we created a plan on how to fight hunger in Niger, both in the short term and in the long term, so we can finally pull ourselves out of this cycle of crisis.
The collapses of authoritarian regimes of the last 15 months should have taught U.S. policymakers one lesson: the old formula of tolerating and colluding with authoritarianism in return for (an often illusory) stability does not work.
The international development community needs to find new ways to support leaders in Africa to do the right thing. No leader deserves a blank check, but it is not enough for us to just say that Africa needs more Mandelas and fewer Mobutus.
The problems I witnessed -- abandonment of children and the brutal view on HIV/AIDS -- are the outgrowth of extreme poverty. Bolivia is the poorest country in South America -- we don't have the luxury to turn our backs.
