Access to clean water is not only one of the world’s most urgent health issues, but it is also a key to boosting progress in developing countries. Women and children are disproportionately affected by inadequate water, sanitation, and hygiene (WASH), and they shoulder the largest burden in collecting drinking water. What is more, when the needs of women and girls are not taken into account, the effects are felt far and wide, reaching across the education, health, security, and economic sectors.  On the other hand, improving WASH can have positive impacts throughout a girl’s life and can even extend across generations. As we know, when women thrive, so do their communities.

“We are in the midst of a silent revolution,” said Ann Pawliczko, a senior technical advisor in the population and development branch at the United Nations Population Fund (UNFPA), quoting former UN Secretary-General Kofi Annan. “It is a revolution that extends well beyond demographics, with major economic, social, cultural, psychological, and spiritual implications.”

You might think that conflict over water is inevitable as rising temperatures and changing climates are expected to constrain supplies in the coming decades at the same time that expanding consumption standards and growing populations are expected to boost demand. But you’d be wrong, according to the United Nations – and they’re launching the International Year for Water Cooperation this week to make that point.

“I’d like to start by stating emphatically that since addressing global inequality and inequity are our overall principles in revising the MDGs [Millennium Development Goals], we must focus on health inequities to have a meaningful and lasting impact on human development,” said Beth Schlachter of the State Department’s Bureau of Population, Refugees, and Migration, speaking at the Wilson Center on January 9. “And for the most vulnerable – women and girls – that means we must focus on sexual and reproductive health and reproductive rights.” [Video Below]

After last spring’s UN Conference on Sustainable Development, popularly known as Rio+20, the Wilson Center’s Paulo Sotero said there was “a sense of frustration over the lack of new commitments from leading countries and participants.” Where do things stand and where are they headed, in light of these disappointments? Were there any silver linings? [Video Below]

Every year the United Nations convenes diplomats from more than 190 nations to negotiate a climate change treaty, and in many years negotiators go home with little more than the promise of another annual meeting.

UNFPA’s recently released State of World Population 2012 brings family planning to the center of the development debate. “There is indisputable evidence that when family planning is integrated into broader economic and social development initiatives, it can have a positive multiplier effect on human development and the well-being of entire nations,” the authors write. The report employs a rights-based approach to make the case for universal access to family planning – a goal which we are far from as 222 million women from the developing world currently have an unmet need for modern contraceptives. Meeting this need and improving quality of reproductive healthcare elsewhere would cost an additional $4.1 billion a year, but save approximately $5.7 billion in maternal and newborn health services. Other recommendations include increasing financial support and political commitment to ensure that family planning is of high quality, reducing the number of unintended pregnancies and abortions, including emergency contraception in family planning services, and engaging boys and men.

The size, composition, and spatial distribution of human populations are constantly changing, and in some areas of the world, they’re changing very rapidly. Related trends in fertility and reproductive health are also in flux. These changes will affect how people experience climate change, both individually and societally.
