When the Nobel Committee awarded the 2007 Nobel Peace Prize to former US Vice President Al Gore, Jr. and the IPCC (Intergovernmental Panel on Climate Change) part of their rationale was

Extensive climate changes may alter and threaten the living conditions of much of mankind. They may induce large-scale migration and lead to greater competition for the earth’s resources. Such changes will place particularly heavy burdens on the world’s most vulnerable countries. There may be increased danger of violent conflicts and wars, within and between states.

So saving the environment is working for peace. A new study from the Norwegian University of Science and Technology (NTNU) says that is only true if the concept of peace is broadened substantially.

The Nobel Committee interprets “working for peace” as including saving the Earth’s environment. Researchers, advocacy groups, politicians and the media have all highlighted local resource crises as the reason for a host of armed conflicts around the globe. The premise underlying the Nobel Committee’s expanded definition of peace is that there is a causal connection between natural resource shortages and violent conflict.

But is that true?

Resources and populations

In their article, the NTNU researchers challenge a popular school of thought, the Neomalthusian school. They see climate change and the over consumption of natural resources as a modern day illustration of Thomas Malthus’ theory.

Thomas Malthus (1766-1834) developed the well-known theory that a country’s food production cannot keep up with its population growth over the long run. Starvation, war and early death would regulate the balance between food availability and population numbers. That means that the bulk of the population would live a minimalist existence.

But Malthus, who lived at the end of the 1700s, couldn’t predict later technological breakthroughs, such as the Green Revolution, which have altered his bleak global caloric intake equation.

A series of case studies in recent years from areas stricken by conflict has helped develop a theoretical basis for the claim that natural resource scarcity leads to armed conflict. Darfur, Sudan, is a recent example of this presumed causal connection, with Rwanda, Haiti and Somalia as other examples.

Helga Malmin Binningsbø, Indra de Soysa and Nils Petter Gleditsch, from NTNU’s Department of Sociology and Political Science, looked at the environmental pressures in 150 countries in the period from 1961 to 1999. By using an internationally recognized technique for measuring a country’s environmental sustainability –“The Ecological Footprint” – the researchers were able to compare these numbers with statistics on armed conflict during the same period.

Their conclusion may seem paradoxical — lands where resources are heavily exploited show a clear connection to a lack of armed conflict. Or, alternatively, nations troubled by war during the research period had lower exploitation rates of their natural resources. The findings give researchers solid empirical support for stating that environmental scarcity is not the reason behind violent conflict.

"A higher Ecological Footprint is negatively correlated with conflict onset, controlling for income effects and other factors," the researchers say in their article, published in the peer-reviewed journal Population and Environment.

"Of course people fight over resources, that’s not our argument. We believe, rather, that we have a strong scientific case against the Neomalthusian model," says Binningsbø.

Darfur

"I have seen with my own eyes how climate change and resource scarcity, particularly when it comes to water and grazing lands, can fuel tensions," says Jan Egeland, director of the Norwegian Institute of International Affairs (NUPI).

Egeland was formerly the UN’s Under-Secretary-General for Humanitarian Affairs and Emergency Relief Coordinator, responsible for refugee issues, and has seen first-hand many conflicts across the globe that surely could have been caused by environmental crises.

Egeland has previously stated that the Darfur conflict was the result of an environmental crisis. He is now a little more uncertain of the causal connection.

"That resource scarcity in specific areas strengthens existing conflicts is something that I have no doubt of," he says. "(But) I still believe that this year’s peace prize award was sound."

The Ecological Footprint

Techniques developed by the Global Footprint Network, an international research network, form the underpinnings for the NTNU group’s research numbers and methods.

"The Environmental Footprint describes a country’s resource consumption compared to its ecological capacity," explain Binningsbø and de Soysa.

The Ecological Footprint measures humankind’s exploitation of natural resources. In other words, how much do you have, and how much do you use?

The method is widely used as a measurement technique, but has also been criticised. Researchers have argued that the method can only be applied on a global basis, in as much as countries trade with each other, and therefore aren’t necessarily solely dependent on their own natural resources.
