To ensure no one is left behind by the next generation of global development goals, a comprehensive mix of robust data is needed to measure progress and guide investments. A recent report coordinated by the Sustainable Development Solutions Network estimates the world will need to spend roughly $1 billion a year to sustain and enhance the statistical systems supporting and evaluating progress towards the Sustainable Development Goals (SDGs), the successors to the Millennium Development Goals expected to guide the development agenda for the next 15 years.

Nepal’s devastating earthquake last Saturday was both tragic and expected. On September 18, 2011, as colleagues and I were driving through Kathmandu, our car started to shake, buildings began to sway, store fronts cracked, hundreds of people jumped out of windows and streamed into already crowded streets. It was the so-called Sikkim earthquake. There were only a few fatalities and injuries – it was a very minor event compared to last weekend’s disaster. But it validated the rationale for our visit: to help launch a disaster relief dialogue involving U.S. government experts, Nepalese security forces, and their country’s emergency responders.

While Chinese officials make full frontal regulatory attacks on smog, untreated sludge, an often toxic byproduct from sewage treatment, continues to quietly spread into groundwater and contaminate soil and food.

This year’s World Water Day is taking on a broader theme than years past: sustainable development. The theme makes sense as two major international processes – the drafting of the Sustainable Development Goals to replace the Millennium Development Goals, and the most anticipated UN Climate Summit in years – are taking place in 2015. Decisions made over the next nine months will play a huge role in relationships between nations and global development priorities going forward.

India is one of the most water-challenged countries in the world, from its deepest aquifers to its largest rivers. Groundwater levels are falling as farmers, new urban residents, and industries drain wells and aquifers. What water is available is often severely polluted, and the future may only be worse, with the national supply predicted to fall 50 percent below demand by 2030.

In 2009, the U.S. Congress passed a five-year, $7.5 billion aid package for a country it had all but abandoned just 10 years earlier. Indeed, if one word can summarize the U.S. relationship with Pakistan, “volatile” might be it. Since the September 11 attacks, the U.S. has appropriated nearly $61 billion in aid to Pakistan – more than twice what it received since independence in 1947.

Accessing maternal health care is already a challenge in many countries, and when conflict erupts or a disaster strikes, it can get even worse, leaving millions of women on their own while at their most vulnerable, said Ugochi Daniels, chief of humanitarian response for the UN Population Fund (UNFPA). Women and girls also become more vulnerable to violence during times of crisis, she said, by virtue of nothing but their gender. [Video Below]
