“The purpose of the whole debate about peak water is to help raise awareness about the nature of the world’s water problems and to help drive toward solutions,” says the Pacific Institute’s Peter Gleick. But Gleick asserts that in the same way certain countries have been contending with “peak oil” concerns in recent years, they may soon also have to deal with “peak water” as well.

Unlike oil, water is largely a renewable resource, but countries in Asia, the Middle East, and elsewhere are pumping groundwater faster than aquifers can replenish naturally. Gleick explains “there will be a peak of production in many of those places and eventually the food that we grow with that water or the widgets that we make from the factories that use that water will be nonsustainable and production will have to drop.”

“The most striking thing about post-conflict and post-disaster environments is that what lurks there is also this extraordinary opportunity,” said Judith Bruce, a senior associate and policy analyst with the Population Council’s Poverty, Gender, and Youth program. Bruce has spent time this year working with the Haiti Adolescent Girls Network (HAGN), a coalition of humanitarian groups conducting workshops focused on the educational, health, and security needs of the country’s vulnerable female youth population.

“When you look at the negative impacts of climate change, the impacts on the poor and the vulnerable – particularly women – increase, so investing in programs that put women at the center is critical,” said Roger-Mark De Souza, vice president of research and director of the climate program at Population Action International (PAI), speaking to ECSP from the UN Climate Change Conference in Cancun, Mexico. “There are a number of missed opportunities here in Cancun and in climate change deliberations overall that are not including women and are missing an opportunity to have a bigger bang for the buck, or power for the peso, as we say in Mexico.”

“Expanding voluntary family planning access and ensuring that all women have access to reproductive health services is, to me at least, a no brainer,” said the Population Institute’s Robert Walker in this interview with ECSP. “I think it’s a win for women, for their health, for their welfare, the welfare of their families, for their communities, for the environment, and for the planet at large.”

“One of the major lessons of 9/11 is that even superpowers can be vulnerable to the grievances emanating from failed and failing states,” said Colin Kahl, now deputy assistant secretary of defense for the Middle East, at an ECSP event at the Wilson Center in October 2007. However, “if poverty and inequality were enough to lead to widespread civil strife, the entire world would be on fire.”

“I think any in-depth examination of particular cases shows that there’s a complex interaction between demographic pressures, environmental degradation and scarcity, and structural and economic scarcities – that they tend to interact and reinforce one another in a kind of vicious circle,” Kahl said.

“It’s really important to keep in mind that any attempt to address…environmental and demographic factors should focus not just on preventing environmental degradation, or slowing population growth, or increasing public health. They must also focus on those intervening variables in the middle that make certain societies and countries more resilient in the face of crisis.”

“The UN projects about 9.1 billion people by 2050, and then population growth will likely level off around 9.5 billion later in the century. Can the planet handle 9 billion? The answer is probably yes. Is it a desirable trajectory? The answer is no,” said John Bongaarts, vice president of the Policy Research Division at the Population Council, in this interview with ECSP.

Although family planning was largely brushed aside by international policymakers following the 1994 UN International Conference on Population and Development in Cairo, Bongaarts said he is hopeful because it is now enjoying a higher profile globally – and receiving greater funding.

“I am optimistic about the understanding now, both in developing and developed world, and in the donor community, that [family planning] is an important issue that should be getting more attention,” Bongaarts said. “And therefore I think the chances of ending up with a positive demographic outlook are now larger than they were a few years ago.”

“We know that when that when we empower women – whether it’s giving them control over their bodies and access to family planning or whether it’s by including them in planning around climate change – their agency can make huge leaps for us,” said Tamara Kreinin, executive director of women and population at the UN Foundation, in this interview with ECSP.

Seventy percent of the world’s poor are women and they’re also the members of the household most likely to be responsible for food, water, and firewood collection.

“At the same time, we know that women are often not at the table,” she said. “They’re not at the table in country when countries are creating aid to adaptation strategies around the environment and climate change, and they’re not at the table at places like Copenhagen and some of the big climate change meetings.”

“Demographics are going to be to the 21st century what class cleavages were to the 19th century,” said Christian Leuprecht in this conversation with the Environmental Change and Security Program. Leuprecht is an assistant professor at the Royal Military College of Canada and was one of the authors featured in ECSP Report 13.

“Specifically with regards to demography and security, the challenge that I see is at the sub-national level. That is to say that most of the conflict, if you look around the world – the intractable conflicts, the violent conflicts, the conflicts that have been dragging on for decades – tend to be at the sub-national level,” he said. “Yet much of the academic work and the way data are gathered are at the national level.”
