Environmental Action Plans in Darfur: Improving Resilience, Reducing Vulnerability
›Many villagers in Baaba, a community of 600 in South Darfur, remember a shady forest of mango and guava trees that provided food and a valuable income for the villagers and a pleasant picnic spot for people in Nyala, the nearby state capital. Over the last decade, that forest has degraded into eroded brush dotted by the occasional baobab – a transformation that is unfortunately a familiar sight throughout Darfur.
Most of Baaba’s trees have become firewood and charcoal for the people living in nearby internally displaced persons (IDP) camps. Baaba’s residents, who themselves returned from the camps to try to rebuild their lives at home, struggle to coax enough food from the soil, which has largely eroded away following deforestation. Afraid to venture any further than necessary from home for fear of violence and banditry in the countryside, they farm and graze the same land year after year without fallow periods – further depleting the soil and driving yields ever lower.
Baaba is like hundreds of Darfuri villages, which face a brutal mix of insecurity and environmental decline that leaves them one poor harvest away from being forced into the IDP camps. Baaba, however, is also a pilot participant in a new approach – the Community Environmental Action Plan – that aims to rehabilitate the local environment, enable people to sustainably manage natural resources, and ultimately to make communities more prosperous and resilient.
Most of Darfur has always been marginal land where farming and herding provide a meager livelihood and natural resources are few. Even before war broke out in 2003, soaring population growth (total population has quintupled since the 1970s) was putting intolerable pressure on the land, water, and trees of Darfur. The conflict in Darfur has since heavily disrupted traditional methods for sharing and maintaining natural resources, leading to environmental devastation. The worsening effects of climate change – though hard to separate from local environmental depletion – are also beginning to disrupt weather patterns and farming. The disheartening result is that even where fighting has subsided and displaced persons return home, they often find that the land no longer sustains them.
Traditional humanitarian aid and infrastructure projects are ill-suited to help, since persistent insecurity deprives humanitarian actors of access to communities for weeks or months at a time. Environmental decline didn’t start the humanitarian crisis in Darfur, but it threatens to prolong it and put a sustainable peace out of reach.
Community Environmental Action PlansThe International Organization for Migration (IOM), mandated to work on IDP and return issues in Darfur, aimed to address these challenges with Community Environmental Action Plans (CEAPs) in three pilot villages. CEAPs build comprehensive local capacity, enabling communities to manage natural resources sustainably and address environmental problems themselves without relying on outside support. The ultimate goal is to build the resilience and adaptive capacity of vulnerable communities. IOM worked with Baaba and two other villages to implement CEAPs, in partnership with the Swiss-based environmental NGO ProAct, the UN Environment Programme (UNEP), the government of South Darfur, and Darfuri environmental organizations. The project, funded by the Government of Japan, ran from early 2009 until mid-2010.
The CEAP process trains communities to understand the connections between a healthy ecosystem and a prosperous community and to promote livelihoods by rehabilitating the environment. Each participating village formed a CEAP governance committee, which was then trained to understand the environment as a single integrated system and to see how damaging one resource like trees can devastate other ecosystem services – such as pollination, groundwater retention, and soil fertility – that enable and promote human livelihoods. The communities then identified essential needs, including reforestation, water harvesting, and improved sanitation, and worked with IOM to develop appropriate responses. These activities were all implemented by the villages themselves, with technical and material support from IOM and its partners.
Building Local Capacity
The communities built low-tech but highly productive tree nurseries, producing and planting over 200,000 seedlings to restore damaged land and provide a sustainable wood supply. Local women learned how to make highly fuel-efficient stoves using locally available materials, cutting their need for firewood and allowing them to sell stoves in the nearby Nyala market.Farmers received extensive training in sustainable agriculture techniques, including water harvesting, composting, agro-forestry, and intercropping (mixing complementary plant species together in the same fields). Volunteers were trained in effective hygiene practices and built latrines for each household. Water committees were trained to repair and maintain the villages’ indispensable but fragile water hand pumps, ensuring a more reliable source of drinking water. Each of these activities was governed by a community committee, including women and youth, trained to manage the projects for the benefit of the entire community and continue the work after the project’s end.
Through this approach, all three villages significantly boosted their livelihoods and agricultural productivity while becoming less dependent on the unsustainable exploitation of their fragile environment. The CEAP approach benefits greatly from focusing on capacity-building and local implementation, which fosters a strong sense of community ownership that persists after the project ends. Equally important, CEAPs attempt to address most or all of a community’s environmental issues simultaneously, reducing the risk that neglected environmental problems – particularly agricultural failure – will critically destabilize and displace a community in the future.
A Replicable Model
CEAPs aren’t a panacea, particularly in the conflict-prone areas where they are most needed. Insecurity, particularly a series of abductions of humanitarian workers from several organizations in 2010, cut off IOM’s access to the communities late in the project. Though the core activities were completed by working through local partners with more reliable access, the security situation left few opportunities for follow-up activities. Longer-term threats, particularly unrestrained population growth – which requires a comprehensive approach that includes addressing unmet need for family planning services – could undo much of the good that CEAPs accomplish.
Though insecurity prevented IOM from continuing the project, other organizations including UNEP are implementing and refining the CEAP approach elsewhere in Darfur and other regions in sub-Saharan Africa. As climate changes intensifies and the potential for related conflicts looms, the CEAP approach should be considered as a powerful and flexible tool to rehabilitate the environment and strengthen vulnerable communities.

Mapping Population and Climate Change
›Climate change, population growth, unmet family planning needs, water scarcity, and changes in agricultural production are among the global challenges confronting governments and ordinary citizens in the 21st century. With the interactive feature “Mapping Population and Climate Change” from Population Action International, users can generate maps using a variety of variables to see how these challenges relate over time.
Users can choose between variables such as water scarcity or stress, temperature change, soil moisture, population, agriculture, need for family planning, and resilience. Global or regional views are available, as well as different data ranges: contemporary, short-term projections (to the year 2035), and long-term projections (2090).In the example featured above, the variables of population change and agricultural production change were chosen for the time period 1990-2020. Unfortunately, no country-specific data is given, though descriptions in the side-bar offer some helpful explanations of the selected trends.
In addition, users can view three-dimensional maps of population growth in Africa and Asia for the years 1990, 2035, and 2090. These maps visually demonstrate the projected dramatic increases in population of these regions by the end of the century. According to the latest UN estimates, most of the world’s population growth will come from Africa and Asia due to persistently high fertility rates.

Climate Change, Development, and the Law of Mother Earth
Bolivia: A Return to Pachamama?
›May 20, 2011 // By Christina DaggettIn Bolivia, environment-related contradictions abound: shrinking glaciers threaten the water supply of the booming capital city, La Paz, while unusually heavy rainfall triggers deadly landslides. The government is seeking to develop a strategic reserve of metals that could make Bolivia the “Saudi Arabia of lithium,” while politicians promote legal rights for “Mother Earth” and an end to capitalism.
This year has been particularly turbulent. In La Paz, landslides destroyed at least 400 homes and left 5,000 homeless. While the rain has been overwhelming at times, it has also been unreliable – an effect of the alternating climate phenomena La Niña and El Niño, experts say, which have grown more frequent in recent years and cause great variability in weather patterns. Bolivia has endured nine major droughts and 25 floods in the past three decades, a challenge for any country but particularly so for one of the poorest, least developed, and fastest growing (with a total fertility rate over three) in Latin America.
Environmental Justice or Radicalism?
Environmentalism has become a major force in national politics in part as a response to the climatic challenges faced by Bolivia. A new law seeks to grant the environment the same legal rights as citizens, including the right to clean air and water and the right to be free of pollution. (Voters in Ecuador approved a similar measure in 2008.) The law is seen as a return of respect to Pachamama, a much revered spiritual entity (akin to Mother Earth) for Bolivia’s indigenous population, who account for around 62 percent of the total population.
Though groundbreaking in its scope, the new law may prove difficult to enforce, given its lack of precedent and the lucrative business interests at stake (oil, gas, and mineral extraction accounted for 70 percent of Bolivia’s exports in 2010).
On the global stage, President Morales has issued perhaps the most aggressive calls yet for industrial countries to do more about climate change and compensate those countries that are already experiencing the effects. Bolivia refused to sign both the Copenhagen and Cancun climate agreements on grounds that the agreements were too weak. In Cancun, Morales gave a blistering speech:We have two paths: Either capitalism dies or Mother Earth dies. Either capitalism lives or Mother Earth lives. Of course, brothers and sisters, we are here for life, for humanity and for the rights of Mother Earth. Long live the rights of Mother Earth! Death to capitalism!
Bolivia’s stance has alienated potential allies: In 2010, the United States denied Bolivia climate aid funds worth $3 million because of its failure to sign the Copenhagen Accord.
Going… Going… Gone
Bolivia’s Chacaltaya glacier – estimated to be 18,000 years old – is today only a small patch of ice, the victim of rising temperatures from climate change, scientists say. Glaciologists suggest that temperatures have been steadily rising in Bolivia for the past 60 years and will continue to rise perhaps a further 3.5-4˚C over the next century – a change that would turn much of the country into desert.
Other Andean glaciers face a similar fate, according to the World Bank, which estimates that the loss of these glaciers threatens the water supply of some 30 million people and La Paz in particular, which, some experts say, could become one of the world’s first capitals to run out of water. The populations of La Paz and neighboring El Alto have been steadily growing – from less than 900,000 in 1950 to more than 2 million in 2011 – as more and more Bolivians are moving from the countryside to the city, putting pressure on an already dwindling water supply.
If the water scarcity situation continues to worsen, residents of the La Paz metropolitan area may migrate to other areas of the country, most likely eastward toward Bolivia’s largest and most prosperous city, Santa Cruz. Such migration, however, has the potential to inflame existing tensions between the western (indigenous) and eastern (mestizo) portions of the country.
Rising Prices, Rising Tension
The temperature is not the only thing on the rise in Bolivia; the price of food, too, is increasing. According to the World Food Program, since 2010, the price of pinto beans has risen 179 percent; flour, 44 percent; and rice, 33 percent. Shortages of sugar and other basic foodstuffs have been reported as well, leading to protests.
In early February, the BBC reported President Evo Morales was forced to abandon his plans to give a public speech after a group of protestors started throwing dynamite. A week later, nation-wide demonstrations paralyzed several cities, according to AFP, closing schools and disrupting services.
The Saudi Arabia of Lithium?
One way out for Bolivia’s economic woes might be its still nascent mineral extraction sector. Bolivia possesses an estimated 50 percent of the world’s lithium deposits (nine million tons, according to the U.S. Geological Survey), most of which is locked beneath the world’s largest salt flat, Salar de Uyuni. The size of these reserves has prompted some to dub Bolivia a potential “Saudi Arabia of lithium” – a title, it should be noted, that has also been bestowed upon Chile and Afghanistan.
Demand for lithium, which is used most notably in cell phones and electric car batteries, is expected to dramatically increase in the next 10 years as countries seek to lower their dependence on fossil fuels. Yet, some analysts have wondered if Bolivia’s lithium is needed, given the quality and current level of production of lithium from neighboring Chile and Argentina.Others have questioned whether Bolivia has the necessary infrastructure to industrialize the extraction process or the ability to get its product to market, though Bolivia recently signed an agreement with neighboring Peru for port access. In an extensive report for The New Yorker, Lawrence Wright writes that “before Bolivia can hope to exploit a twenty-first century fuel, it must first develop the rudiments of a twentieth-century economy.” To this end, the Bolivian government last year announced a partnership with Iran to develop its lithium reserves – a surprising move, given Morales’ historical disdain for foreign investment.
Nexus of Climate, Security, Culture, and Development
The Uyuni salt flats are both a potent economic opportunity and one of the country’s most unspoiled natural wonders. How will Bolivia – a country of natural bounty and unique indigenous tradition – balance the need for development with its stated commitment to environmental principles?
Large-scale extraction may be worth the environmental cost, a La Paz economist told The Daily Mail: “We are one of the poorest countries on Earth with appalling life-expectancy rates. This is no time to be hard-headed. Without development our people will suffer. Getting bogged down in principles and politics doesn’t put food in people’s mouths.”
“The process that we are faced with internally is a difficult one. It’s no cup of tea. There are sectors and players at odds in this more environmentalist vision,” said Carlos Fuentes, a Bolivian government official, to The Latin American News Dispatch.

Connections Between Climate and Stability: Lessons From Asia and Africa
›“We, alongside this growing consensus of research institutes, analysts, and security agencies on both sides of the Atlantic, think of climate change as a risk multiplier; as something that will amplify existing social, political, and resource stressors,” said Janani Vivekananda of International Alert, speaking at the Wilson Center on May 10. [Video Below]
Vivekananda, a senior climate policy officer with International Alert’s Peacebuilding Program, was joined by co-presenter Jeffrey Stark, the director of research and studies at the Foundation for Environmental Security and Sustainability (FESS), and discussant Cynthia Brady, senior conflict advisor with USAID’s Office of Conflict Management and Mitigation, to discuss the complex connections between climate change, conflict, stability, and governance.
A Multi-Layered Problem
Climate change and stability represent a “double-headed problem,” said Vivekananda. Climate change, while never the only cause of conflict, can increase its risk in certain contexts. At the same time, “states which are affected by conflict will already have weakened social, economic, and political resilience, which will mean that these states and their governments will find it difficult to address the impacts of climate change on the lives of these communities,” she said.
“In fragile states, the particular challenge is adapting the way we respond to climate change, bearing in mind the specific challenges of operating in a fragile context,” said Vivekananda. Ill-informed intervention programs run the risk of doing more harm than good, she said.
For example, Vivekananda said an agrarian village she visited in Nepal was suffering from an acute water shortage and tried adapting by switching from rice to corn, which is a less water-intensive crop. However, this initiative failed because the villagers lacked the necessary technical knowledge and coordination to make their efforts successful in the long term, and in the short term this effort actually further reduced water supplies and exacerbated deforestation.
“Local responses will only be able to go so far without national-level coordination,” Vivekananda said. What is needed is a “harmony” between so-called “top-down” and “bottom-up” initiatives. “Adapting to these challenges means adapting development assistance,” she said.
“What we’re finding is that the qualities that help a community, or a society, or in fact a government be resilient to climate change are in fact very similar qualities to that which makes a community able to deal with conflict issues without resorting to violence,” said Vivekananda.
No Simple, Surgical Solutions
“The impacts of environmental change and management of natural resources are always embedded in a powerful web of social, economic, political, cultural, and historical factors,” said Stark. “We shouldn’t expect simple, surgical solutions to climate change challenges,” he said.
Uganda and Ethiopia, for example, both have rich pastoralist traditions that are threatened by climate change. Increasing temperatures, drought, infrequent but intense rains, hail, and changes in seasonal patterns are threatening pasture lands and livelihoods.
At the same time, pastoralists are confronting the effects of a rapidly growing population, expanding cultivation, forced migration, shrinking traditional grazing lands, anti-pastoralist attitudes, and ethnic tensions. As a result, “any intervention in relation to climate adaptation – whether for water, or food, or alternative livelihoods – has to be fully understood and explicitly acknowledged as mutually beneficial by all sides,” Stark said. “If it is seen in any way to be favoring one group or another it will just cause conflict, so it is a very difficult and delicate situation.”
Yet, the challenges of climate change, said Stark, can be used “as a way to involve people who feel marginalized, empower their participation…and at the same time address some of the drivers of conflict that exist in the country.”
Case Studies: Addressing the “Missing Middle”
When doing climate change work in fragile states, “you have to think about your do-no-harm parameters,” said Brady. “Where are the opportunities to get additional sustainable development benefit and additional stabilization benefit out of reducing climate change vulnerability?”
More in-depth case studies, such as the work funded by USAID and conducted by FESS in Uganda and Ethiopia, are needed to help fill the “missing middle” between broad, international climate change efforts – like those at the United Nations – and the community level, Brady said.
The information generated from these case studies is being eagerly awaited by USAID’s partners in the Departments of State, Defense, and Treasury, said Brady. “We are all hopeful that there will be some really significant common lessons learned, and that at a minimum, we may draw some common understanding about what climate-sensitive parameters in fragile states might mean.”

Watch: Edward Carr on Delivering Development and Rethinking Assumptions
›May 13, 2011 // By Schuyler NullWhile visiting West Africa first as an archaeologist, Edward Carr, an associate professor in the Department of Geography at the University of South Carolina and author of Delivering Development: Globalization’s Shoreline and the Road to a Sustainable Future, found that the villages in which he was working were far more resilient to the impacts of climate change than he expected. Increased frequency of drought, declines in rainfall, severe storms – these challenges are the sort of thing that can “totally destroy someone’s livelihood in a year,” he said in an interview with ECSP, “yet they were surviving and surviving really, really well.”
That experience and others challenged his understanding of “how I thought the world was supposed to work, how I’d been taught the world was supposed to work, versus what I was actually seeing happen on the ground,” said Carr. “I became so struck by what people were dealing with in the current context that my interest started to shift much more towards what they were doing now.”
Now serving as a AAAS fellow and the climate change coordinator for the Bureau for Democracy, Conflict, and Humanitarian Assistance at the U.S. Agency for International Development, Carr said he is trying to change how the U.S. government does development.
“The last 13 years of my career have been trying to figure out what’s actually happening on the ground first,” Carr said, and that led to writing Delivering Development.
“One of the key arguments I have is that the world does not work the way we assume it does – we are fundamentally misunderstanding what’s happening for most people living out, especially in rural areas, in the developing world,” said Carr. “The challenges they face are significant but not necessarily the ones we’re aimed at.”
For example, said Carr, “we see rising food prices globally and…the presumption is that the poorest people in the world are going to get really hammered by this.” But, he said, “That’s not entirely true, because a lot of the poorest people in the world living in rural areas have an option to just disconnect from markets completely – they go total subsistence if they need to.”
There’s an assumption that people shouldn’t be disconnecting like that, but, Carr pointed out, when new places are integrated into larger markets, “we’re also integrating them into new sources of risk that they may not be very well equipped to manage, and that becomes a really significant challenge.”
“We’re starting with the fundamental assumption that markets can be a solution, without necessarily really looking carefully at how markets can be part of the problem,” said Carr. -
Population Growth and Climate Change Threaten Urban Freshwater Provision
›May 6, 2011 // By Emanuel FeldBy 2050, more than one billion urban dwellers could face perennial freshwater shortages if major improvements are not made to water management practices and infrastructure, according to a recent study published in the journal PNAS, “Urban Growth, Climate change, and Freshwater Availability.” These challenges will arise as hydrologic changes due to climate change compound “an unprecedented wave of urban growth,” with nearly three billion additional urban residents forecast by 2050. “It is a solvable problem,” the study argues, “but one that will take money, time, political will, and effective governance.”
Using demographic data from the Earth Institute at Columbia University, as well as a variety of climate and city-level demographic scenarios, the researchers estimate per-capita water availability for cities in the developing world, where urban growth will be most rapid. They advise, however, that their findings should be taken as conservative estimates, since the study assumes cities can use all nearby water and does not account for key challenges relating to water quality and delivery to urban centers.
In 2000, 150 million people in developing countries lived in urban areas that could not support their own water requirements (i.e. less than 100 liters available per person per day). By 2050, according to the study, urban population growth alone could bring this figure to 993 million and more than three billion could face intermittent shortages at least one month out of the year. When the researchers expanded the area on which cities can draw upon to include a 100 km buffer zone, these values drop to 145 million and 1.3 billion, respectively.
However, once climate and land use change are included in the models, the aggregate number of people facing perennial shortages rises a further 100 million, if only water stores within the urban area are considered, or 22 million, for the 100 km buffer zone model.
Remarkably, these aggregate figures differ very little among the various demographic and climate scenarios. The particularities of the challenge do however vary at the regional level. Perennial water shortage will generally be limited to cities in the Middle East and North Africa. Seasonal water shortages, on the other hand, will be geographically widespread, although rapidly urbanizing India and China will be especially hard hit.
The study acknowledges the temptation to view water shortage “as an engineering challenge.” Still, the lead author, Rob McDonald of The Nature Conservancy, cautions against exclusive reliance on grey infrastructure solutions (e.g. canals and dams) in an article for Nature Conservancy, saying:Some new infrastructure will be needed, of course – that’s the classic way cities have solved water shortages. But especially in parts of the world where there’s lots of cities, just going out farther or digging deeper to get water can’t be the only solution.
Instead, McDonald and co-authors Pamela Green, Deborah Balk, Balazs M. Fekete, Carmen Revenga, Megan Todd, and Mark Montgomery, emphasize the need for cities to encourage more efficient water use by their industrial and residential sectors, as well as the potential to engage the water-intensive agriculture sector in surrounding rural areas.
“Bottom line,” McDonald said in an interview with Robert Lalasz of The Nature Conservancy’s Cool Green Science blog, “don’t think of those high numbers as a forecast of doom. They are a call to action.”

Where Does It Hurt? Climate Vulnerability Index
›The original version of this article appeared in the University of Minnesota’s Momentum Magazine. Text by Mary Hoff, page layout by Todd Reubold.
The punch climate change packs varies from one country, region, or continent to another. DARA, a Madrid-based humanitarian advocacy organization, recently partnered with the Climate Vulnerable Forum, comprising countries particularly vulnerable to climate change, to create Climate Vulnerability Monitor 2010, an atlas of vulnerability. This infographic presents a small portion of the picture the Climate Vulnerability Monitor paints.
Vulnerability is grouped into four categories: health impacts, weather disasters, habitat loss and economic stress. Circles on the left side of each set indicate relative magnitude of vulnerability in 2010. Circles on the right indicate the same for 2030.

Managing Our Forests: Carbon, Climate Change, and Fire
›“We cannot manage our planet if we cannot manage our forests,” said William Sommers, a research professor with the Center for Climate and Society at George Mason University, during a recent event at the Woodrow Wilson Center. The event, which coincided with the International Year of Forests, was the fourth in a series co-sponsored by George Mason University and the Environmental Change and Security Program on “Managing the Planet.” Sandra Brown, director and chief scientist of the Ecosystems Services Unit at Winrock International and David Cleaves, climate change advisor to the chief of the U.S. Forest Service, joined Sommers and moderator Thomas Lovejoy, professor at George Mason, to discuss the impact of climate change, carbon, and fire on the world’s forests. [Video Below]
Fire: A “Critical Element”
“Forests have evolved over Earth’s history,” said Sommers, with fire being a “constant shaper” of this evolution. Humans first used fire as a tool about 400,000 years ago, and around 10,000 years ago, we began using fire for agricultural purposes, which, Sommers said, can be considered the beginning of forest management.
The resulting carbon dioxide (CO2) emissions have been an important consequence of this human intervention, Sommers said. CO2 emissions have an “exceptional persistence” in the atmosphere, which, explained Sommers, “commits us to irreversible warming over the next 1,000 years.”
In order to counteract these warming effects, a replacement for the “business-as-usual” approach is needed, Sommers said. If not, he warned, CO2 concentrations could reach a thousand parts per million by the end of the century: “It has been 30 to 100 million years since Earth experienced that level of atmospheric CO2 concentration, and Earth was extremely warm at that time.”
“Fire remains a critical element of the earth’s system and is highly sensitive to climate change,” said Sommers. The potential feedback relationship between fire and climate change was illustrated in dramatic fashion in the summer of 2010 with the outbreak of wildfires in Russia after the hottest summer temperatures on record.
Time is running short, Sommers warned, to answer the question of whether humans can anticipate and respond to climate change and manage forests in a sustainable manner.
Reducing Emissions & Improving Management
“Logging can be well-planned and well-designed or maybe not so well-planned,” said Brown as she spoke about her research on the logging industry in the tropics. Sustainable forest management in the tropics is still “a bit of the wild west” in some countries, though the situation is improving slightly, she said.
One way to improve management and reduce greenhouse gas emissions would be through the REDD+ (Reducing Emissions from Deforestation and Degradation) program of the United Nations. REDD+ can provide incentives, Brown said, for people to come up with useful innovations and improvements to forest management. But, she warned, “the longer we keep waiting, [the more] forests are diminishing.”
When a tree is felled, Brown said, there is a lot of collateral damage. An estimated one billion metric tons of CO2 are released every year from logging in the tropics of Africa and Latin America, she explained. One-half of these emissions are from the harvesting itself and the other half is from incidental damage and infrastructure, such as from the skid trails and haul roads needed to transport the logs out of the forest.
Therefore, it is important for all possible reduction steps to be taken, Brown said: “Where we have opportunities to produce goods with reducing emissions, we need to take those opportunities. We just can’t keep thinking, ‘That’s too small to worry about.’ If there’s what we call ‘low-hanging fruit,’ why not go for it?”
In order to reduce emissions and improve management, Brown suggested reducing avoidable waste by trimming more off of felled logs to increase volume, creating a management plan wherein felled logs are accurately mapped and skid trails are better planned, and using silvicultural treatments to speed the forest’s recovery.
Integrating Climate Change Into Risk Management
The job of the U.S. Forest Service has always been that of a “stress manager,” said Cleaves. Climate change is likely to ramp up existing stressors, such as drought and wildfires, which is why it is necessary for the Forest Service to integrate climate change adaptation techniques into the existing stress manager role. “We feel that there is no such thing as a separate climate change program,” he said.
Many difficult choices will have to be made to address climate change, Cleaves said: “We can’t afford the scale of the problem; we can’t afford to solve it all. We need to be able to prioritize.” These choices will have to be based on economic, social, and ecological values in order to “manage risks around the full sweep of the elements of sustainability,” he said.
The country’s forests are changing and we have already seen whole system change, Cleaves explained. For example, climate change has altered snow cover patterns leading to the decline of over half a million acres of yellow-cedar forest in Alaska.
Other threats facing U.S. forests include disease (such as white pine blister rust), increased variability of fires, increased housing growth near forested areas, and the possibility of forests turning from carbon sinks into carbon sources. That is to say, as forests are destroyed through fires, clearing, or disease, they release back into the environment the carbon they have absorbed.
Risk must be integrated into the decision-making process of the agency, and to this end the Forest Service has created the National Roadmap for Responding to Climate Change. But in order to meet these climate change challenges, Cleaves said, “we have to get moving.”
