Georgina Mace on Planetary Stewardship in a Globalized Age: Risks, Obstacles, and Opportunities
›April 18, 2012 // By Stuart Kent“The goal, ultimately, is just to manage our world better,” to have an “integrated system for the environment that is driven by what local communities want and need,” said Professor Georgina Mace, director of the NERC Centre for Population Biology at Imperial College London. Mace spoke to ECSP on the sidelines of the 2012 Planet Under Pressure conference.
The environmental challenges of humanity are “really twofold,” she said. First, “human societies have grown up at what we now call the local scale…traditionally using the area in which they live.” Communities have always exerted pressures on their local environment but population growth “means those pressures on local landscapes are much greater than they use to be,” said Mace. “We can’t do everything all in the same place,” without the needs of different groups sometimes conflicting.
Second, “there are connections between societies that are sometimes good but quite often they’re damaging.” For example, the increasingly globalized nature of how we utilize natural resources means that “overuse by one community may affect local people in ways that they have no way of responding to.”
Taking apart the first of these challenges, Mace explained that “the population growth issue is really a population growth and demographic change [issue].” In places with mature age structures, such as North America, Europe, Russia, South Korea, and Japan, “the concern is about the number of old people dependent on a reducing number of producers in their society,” while in many poorer regions of the globe the concern is about the “many young people who still have to go through their reproductive years.”
This latter case “looks a horrible problem from the environment point of view,” said Mace, because the areas growing fastest are areas that are “already overused in many ways.” If countries “don’t worry too much about international migration [and] we’re able to accommodate that,” this “demographic divide” could actually be helpful, as countries with growing populations could provide a young, energetic workforce to those that are aging.
Mace made policy recommendations on different scales, from the local to the planetary. At the local level she encouraged making sure that climate interventions “are actually in concert with what’s going on in the environment.” “Let’s take advantage of ecological resilience, biological adaptation – all the things that nature has provided us with that give us mechanisms for coping,” she said.
On a broader scale, she recommended intervening to counteract the “damaging drivers of environmental change,” by using geoengineering and better land use planning, “which is essentially gardening the planet.”
“Both of those offer solutions that are actually incredibly efficient. They also have costs, risks, and obstacles to do with governance, to do with different people being winners and losers, and to do with the fact that we tend to organize our world around nation states and these solutions mostly transcend international boundaries.”
“That’s a major obstacle,” Mace said, but in the end we need “to have a fully integrated planning system that is not top down but has an overall strategy that seeks to optimize all the things that people want and allows a way for local communities to connect.”
“I think that’s the big challenge for us – how to get there.” -
Neil Adger: Embrace Community Identities To Improve Climate Adaptation
›April 16, 2012 // By Stuart Kent“On an individual basis, people care about things in their back garden and they also care about global icons of climate change…cultural heritage and natural heritage are two really important things that tie people to place and where the impacts of climate change are really going to be felt,” said Neil Adger, professor of environmental economics at the University of East Anglia and the Tyndall Centre for Climate Change Research.
Speaking at the Wilson Center, Adger explained that if policymakers don’t think seriously about the cultural dimensions of climate change adaptation they risk implementing measures that significantly, and negatively, impact people’s sense of community and identity.
“For more than a decade we have been looking at the economic costs, and the infrastructure, and the things that policymakers really focus on whenever they think about the impacts of climate change,” said Adger. In doing so “we realized that that doesn’t necessary motivate people in terms of what they believe the impacts of climate change are.”
Drawing from work on adaption in Australian agriculture, Adger explained that culture can be a barrier to effective adaptation where governments and policymakers fail to engage communities on a cultural basis.
More detailed information is needed to identify what people care about, how people construct perceptions of climate risk, and the best ways to engage people locally.
This is not easy, however. “I think the difficulty of looking at the cultural impacts of climate change is that they are very place specific,” Adger said.
But there is a significant payoff from the investment. “The cultural embedded-ness of our relationship with climate is also potentially a huge motivation for action and for change,” he said. This motivation can extend beyond adaptation to actually encourage people to decarbonize the economy, to mitigate the potential for negative climate change impacts in the first place, and to act as “citizens rather than as consumers.” -
Geoff Dabelko On ‘The Diane Rehm Show’ Discussing Global Water Security
›April 13, 2012 // By Wilson Center StaffECSP Director Geoff Dabelko was recently a guest on The Diane Rehm Show to discuss the just-released U.S. intelligence community assessment of world water security. He was joined by co-panelists retired Maj. Gen. Richard Engel (USAF) of the National Intelligence Council’s Environment and Natural Resources Program (a key figure in preparing the report), Jessica Troell of the International Water Program at the Environmental Law Institute, and Steve Fleischli of the Natural Resources Defense Council.
The Department of State-requested assessment (outlined in more detail, here and here) is a very positive contribution, said Dabelko. It “moves away from the arm-waving, headline-grabbing, water wars frame – the kind of sky-is-falling frame that is intuitively appealing and certainly appealing for politicians and headline writers, but doesn’t really reflect the reality.” He continued:What this report instead does, is recognize that there’s been an awful lot of cooperation around water even in the face of scarcity and that that cooperation in part helps us avoid conflicts, whether they’re violent or political, and that we should invest in those institutions that help us get to cooperation.
Visit the show’s program page to listen to the full segment, or read the transcript here.
It also suggests that it’s inadequate and incorrect to think of water as just a single-sector issue. The report is quite clear in connecting it to energy, connecting it to food, connecting it to health, economic development, agriculture obviously, and so that recognition [in] analysis sounds in some way straightforward, but unfortunately, when we organize our responses, we often respond in sector, and there’s not nearly enough communication and cooperation.
And finally, the report does say that the future may not look like the past, and so while we don’t have evidence of states fighting one another over water – and the judgment of the report is in the next 10 years, we won’t see that – it does hold out the prospect for as we go farther down the line, in terms of higher levels of consumption and higher levels of population, that we need to pay special attention because there’s some particular river basins in parts of the world where, as I said, the future may not look like the past and we have greater concerns for higher levels of conflict.

Reproductive Health an Essential Part of Climate Compatible Development
›April 11, 2012 // By Sandeep BathalaECSP was at London’s 2012 Planet Under Pressure conference following all of the most pertinent population, health, and security events.
At a panel on “climate compatible development” at this year’s Planet Under Pressure global change conference, Population Action International’s Roger-Mark De Souza was the lone voice to speak about demographics. He presented a detailed analysis of population trends, based on collaboration with the Kenya-based African Institute for Development Policy.
“The link between population dynamics and sustainable development is strong and inseparable – as is the link between population dynamics, reproductive health, and gender equality,” said De Souza. These linkages were emphasized by the UN at the International Conference on Population and Development, held in Cairo in 1994, as well as during the original Rio Conference on Environment and Development in 1992.
“Climate compatible development” is a novel development paradigm being developed by the Climate and Development Knowledge Network and defined as “development that minimizes the harm caused by climate impacts, while maximizing the many human development opportunities presented by a low emissions more resilient future.”The key tenet of this development framework is an emphasis on climate strategies that embrace development goals and integrate opportunities alongside the threats of a changing climate. In this respect, climate compatible development is seen as moving beyond the traditional separation of adaptation, mitigation, and development strategies. It challenges policymakers to consider “triple win” strategies that result in lower emissions, better resilience, and development – simultaneously.
Although developed nations are historically the major contributors of greenhouse gases due to comparatively high levels of consumption, developing countries are the most vulnerable to consequences of climate change. Emerging evidence shows that rapid population growth in developing countries exacerbates this vulnerability and undermines resilience to the effects of climate change, said De Souza. Socioeconomic improvement will also increase the levels of consumption and emissions from developing countries.
“Meeting women and their partners’ needs for family planning can yield the ‘triple win’ strategy envisaged in the climate development framework,” De Souza said. “Meeting unmet family planning needs would help build resilience and strengthen household and community resilience to climate change; slow the growth of greenhouse gases; and enhance development outcomes by improving and expanding health, schooling, and economic opportunities.”
Decision makers engaged in climate change policy planning and implementation at local, national, and international levels should have access to evidence on population trends and their implications on efforts to adapt to climate change as well as the overall development process, De Souza said.He presented new maps and analysis for Africa, particularly Malawi and Kenya, developed by PAI, building on earlier mapping work which identified 26 global population and climate change hotspots – countries that are experiencing rapid population growth, low resilience to climate change, and high projected declines in agricultural production.
“PAI’s work is a clear demonstration of how better decision making can be informed by the right analysis, in the right format, at the right time,” said Natasha Grist, head of research at the Climate Knowledge and Development Network.
“Most of the hotspot countries have high levels of fertility partly because of the inability of women and their partners to access and use contraception,” said De Souza. He continued:Investing in voluntary health programs that meet family planning needs could, therefore, slow population growth and reduce vulnerability to climate change impacts. This is especially important because women, especially those who live in poverty, are likely to be most affected by the negative effects of climate change and also bear the disproportionate burden of having unplanned children due to lack of contraception.
In conclusion, said De Souza, “global institutions and frameworks that support and promote climate compatible development can enhance the impact of their work by recognizing and incorporating population dynamics and reproductive health in their adaptation and development strategies.”

Demography, Climate in the Spotlight at Planet Under Pressure
›March 27, 2012 // By Kayly OberLondon’s 2012 Planet Under Pressure conference, on all things global change – including climate, population, global risks, and food security – kicked off with a bang on March 26 and ECSP was there to cover it. We’ll be here throughout the week following all of the most pertinent population, health, and security events – we invite you to visit our booth if you happen to be in London, join the conversation on Twitter (#Planet2012), and/or watch the livestream.
During the opening plenaries, UK Scientific Advisor and all-around environmental all-star Sir John Beddington was the first to introduce population into the discussion.
Speaking on “The Planet in 2050” panel, Beddington immediately noted that really 2050 is too far out and instead we should focus on the next two decades. Within these 20 years the trajectory of greenhouse gas emissions and climate change will be determined by the extent and manner of urbanization and demographic changes, particularly in Africa.
“How are we going to generate an infrastructure to feed 500 million Africans in the next 13 years?” Beddington asked.
Beddington’s talk could be considered a rejoinder to his famous “perfect storm” analogy, outlined in The Guardian in 2009:Our food reserves are at a 50-year low, but by 2030 we need to be producing 50 percent more food. At the same time, we will need 50 percent more energy, and 30 percent more freshwater.
In a later session, “Securing Global Biodiversity,” Simon Stuart, chair of the species survival commission of the International Union for Conservation of Nature (IUCN), expanded on this “perfect storm” analogy.
There are dramatic problems out there, particularly with water and food, but energy also, and they are all intimately connected. You can’t think about dealing with one without considering the others. We must deal with all of these together.
He agreed that the global challenge of our day hinged on how human needs add pressures to the natural environment. Rising demand for energy, food, and freshwater not only influences climate change but also exerts unprecedented pressure on soil quality and biodiversity.
But although we’re impeded by major challenges, including “unsustainable economic models,” a lack of public support, and a massive need for investment in conservation, we have made some strides, Stuart said. The Convention on Biological Diversity’s strategic plan for biodiversity, established in 2010, sets 20 targets for biodiversity conservation by 2020. Stuart believes this is the beginning of acknowledging the urgency of addressing the threat to biodiversity.
Tim Coulson, professor of population biology at Imperial College London, compared the efficiency of either reducing fertility rates or per capita consumption to determine the best way to reduce humanity’s impact on the planet.
Coulson ran two simple simulations using India and the United States as case studies. In one model, he changed fertility rates by one percent per year for 50 years. In the other, he decreased per capita consumption by one percent per year for 50 years. What he found in both cases was that decreasing per capita consumption achieved the most rapid change in human impact on the environment. Nevertheless, he acknowledged that a longer-term course of action of declining fertility rates was needed to keep impact stable.
Readers beware, however – this type of experiment is an incredibly simplified exercise in the intersection of people and the environment. A more varied set of scenarios would produce more useful results. As Beddington mentioned, populations in sub-Saharan Africa have both the highest growth rates and the most direct impact on the environment due to their higher reliance on natural resources for livelihoods.
And, perhaps most importantly, as one commentator noted, these scenarios do not take into account cost factors. For instance, in order to reduce greenhouse gas emissions through more energy efficient buildings and transport, the United States would need to invest $1.1 trillion through 2030. Alternatively, the cost to provide for the 215 million women in developing countries who want to avoid pregnancy but are not using an effective means of contraception is estimated at $3.6 billion. Using the “wedge” climate model, meeting unmet family planning needs would be equivalent to the amount of greenhouse gas emissions saved by converting entirely to electric vehicles – at a fraction (about five percent) of the cost.
Stay tuned for more updates from ECSP at the Planet Under Pressure Conference. We’ll also be posting pictures from the conference to our Facebook and Flickr pages.

Fourth World Water Development Report Released by UN
›The beginning of last week’s World Water Forum in Marseille also marked the release of UNESCO’s fourth edition of the World Water Development Report. Chief amongst the challenges outlined in the new report are meeting demand from growing population and consumption. Agriculture accounts for 70 percent of water usage, according to the report, and globally we will require 70 percent more food over the next 40 years, introducing the possibility of overtaxing already-stressed water resources – all while adapting to climate change. There are substantial gains to be had in increasing farm-to-table efficiency, especially in developing countries, the authors sagely point out, but the supply challenge remains a huge one.
This year’s edition also adds several new sections, including on women and water. “The crisis of scarcity, deteriorating water quality, the linkages between water and food security, and the need for improved governance are the most significant in the context of gender differences in access to and control over water resources,” write the authors. “These challenges are expected to become more intense in the future.”
The integrated nature of today’s water issues is a highlight throughout the report. “Accelerated change” will create new threats and “interconnected forces” create uncertainty and risk, but UNESCO emphasizes that if policymakers are made aware of these issues, ultimately “these forces can be managed effectively and can even generate vital opportunities and benefits through innovative approaches to allocation, use, and management of water.”

John Williams: Helping People and Preserving Biodiversity Hotspots
›March 16, 2012 // By Schuyler Null“Both humans and the number of species in the world are not evenly distributed across the globe,” said John Williams of the University of California, Davis, who recently spoke at the Wilson Center about his contribution to Biodiversity Hotspots: Distribution and Protection of Conservation Priority Areas. “In particular we find that species diversity is concentrated in what’s called the biodiversity ‘hotspots.’”
Largely in the tropics, Mediterranean climates, and along mountain chains, biodiversity hotspots are “where there’s a real concentration in number of species and also unique species – plants and animals that exist nowhere else on Earth,” he said.
“It’s a very complex relationship between biodiversity and human population, because it’s not necessarily [true] that places of high human population are a threat to biodiversity,” said Williams. Many different factors play a role, “like education, like consumption, like economic development, different cultures – how people interface with the natural world – all these things create nuances as far as what that relationship is between biodiversity and where people live.”
“There are some basic things we can do that are going to be good for human welfare, as well as biodiversity,” he continued. A few are addressing lack of education, especially among girls, in areas of high biodiversity; providing basic health services, including family planning, where rural growth rates are highest; and improving physical access to rural areas to promote economic development.
“We see there’s a direct correlation between each additional year of schooling a girl has and their fertility during their lifetime,” Williams said. “As people climb out of poverty, they also choose to have smaller, healthier families.”
