Climate Migration: A Cause and Effect

Climate Migration: A Cause and Effect

We watched the events of this year unfold from our couches. News of the pandemic’s spread had most of the population home and baking, breaking out board games and books to alleviate boredom. When election week got too stressful, or we read about yet another jihadist attack, or another Black American’s arrest gone disturbingly wrong, or the latest statistics on worsening climate change, we fought back with activism, yes, but also with self care. We watch the news on our couches, with our loved ones, light scented candles and buy another fluffy blanket as the cold weather sets in, as we contemplate the world’s most deeply rooted inequities. It is our right—self care is crucial to sustaining mental health so that we have the energy to keep fighting for change. But it’s also a luxury denied to the very people we fight for. As we munch on our homemade sourdough starters and shake our heads at the latest “presidential” tweet, there are people around the world who are so affected by global events that they lose, rather than retreat to, the homes they want to feel just as safe in as we do ours. Migrants and refugees have been a historical reality as long as the concept of borders has existed, but the causes of flight, the perils of that process, and its longterm ramifications are now more interconnected and alarming than ever. 

In my most recent articles, I examined the links between climate change and natural disasters like droughts, hurricanes, and wildfires. Events like these, but also places with conditions of less immediacy, which nonetheless experience the effects of a changing climate, make many of the world’s most vulnerable places unlivable, resulting in migration. Such migration can occur within a country but also across national borders and even across continents. These movements and influxes of large, heterogeneous groups of migrants and refugees are both caused by environmental degradation and often unwitting contributors to that very same process. Yet despite, and perhaps because of this vicious cycle, humanitarian efforts to support these groups, especially during a global pandemic, are more crucial both to the wellbeing of migrants and to the environment than perhaps ever before.

While migration can be spurred by a variety of push and pull factors, when one examines the climate/environment as a catalyst for movement, there are several main causes, as outlined in this study. Migration induced by environmental disasters, like those mentioned above, is one. Migration caused by longterm environmental degradation, like resource strain due to overpopulation, is another main cause. Finally, long term effects of climate change like rising sea levels and shifts in disease patterns due to changes in weather regimes and temperature change also drives migration.

While the idea of migration might most readily bring to mind the entrance and assimilation of large groups from political conflict areas into the West, the reality of migration is nuanced, occurring over vastly different timelines and over varying geographic scales. Whether the movement is international or simply regional, the amount of people migrating, the reason for their migration, and the resources available for their support upon arrival all have ramifications both for the environment in the receiving territory and for the migrants themselves. Studies of internal migration show that “settlement into marginal and fragile ecosystems in [Least Developed countries] have led to desertification, deforestation and other environmental degradation.” Another study finds that migration from developing to developed countries causes an absolute increase in global emissions not just from the process of movement but also from environmental damage in the areas in which they settle. In developed countries, this means increased total emissions as migrant populations settle into the energy consumption patterns associated with higher income level urban areas, as well as loss of biodiversity, soil quality, deforestation, water pollution, and deterioration of natural areas responsible for carbon sequestration for migrants who settle in and develop more rural areas. These problems make living in migrant settled areas difficult not just for existing local populations but also for the migrants themselves.

The environmental problems in connection with the multiple stages of migration result from a lack of efficient management and planning. Understandably, the immediate wellbeing of refugee populations is the priority, but approaching the task of planning a refugee settlement cannot be dictated by short-term goals when such settlements are often longterm establishments, existing on average for 17 years. This is long enough to irreversibly damage the local environment of the settlement. Camp overcrowding, while a humanitarian issue, is also an environmental one, as local water and tree supplies diminish dangerously. The UNHCR created a tool to assess environmental impact in 2005, yet the focus remains on a “curative” rather than prevention-oriented approach. In some places, if the potential financial and social burden of supporting refugees does not dissuade a host country from accepting refugees, the damage to the environment that persists long after might act as a disincentive for aid. This article points out that after examining case studies in rural camps like that of 80,000 Nigerian refugees in Northern Cameroon and Syrian refugee camps in urban Lebanon, it is clear that “despite the gradual introduction of the term “environment” as a cross-cutting issue in policies and strategies, environmental issues are generally perceived as being separate from the humanitarian sector…humanitarian crises can have a significant impact on the natural environment, particularly when these are prolonged crises.”

Migration, whether for political, environmental, or other reasons, is predicted to increase in the coming decades, but it must do so in a way that protects both the displaced groups and their destinations. Establishing new urban centers in migratory destinations is one proposed sustainable solutionAs a whole, planning and facilitating migration as a lifesaving option for vulnerable groups that does not jeopardize future environmental health must be prioritized in the conversation on migration, not just in addition to humanitarian aims but as a humanitarian aim in itself.

This year, the pandemic raised many questions about borders, international rights, and the priorities of governments. Within weeks of COVID-19’s spread across the globe, travel between the Unites States and Europe, and indeed between European countries, halted—and still has not been completely restored. In difficult times, the instinct of many is to protect those closest to them: family, neighbors, those with the same nationality. Asylum procedures were similarly disrupted. Displaced people became some of the most vulnerable to exposure to the virus due to cramped living conditions and shared resources, and their need was more urgent than ever. The pandemic serves as a powerful reminder of the world’s connectedness, but also of how differently people experience the same problems. Climate change causes migration, which causes environmental degradation and furthers the spread of the virus, which might lead to more inaction on climate change as leaders struggle to deal with the most immediate global issues at the direct expense of ongoing ones; it’s a brutal cycle that can only be broken with empathy, knowledge, and planning.

There’s something unsettling about the virus, this seemingly inescapable, omnipresent, insidious force that keeps us locked in our homes. Some people almost wished for a tangible enemy, something obvious and terrifying but at the very least visible, so that they could justify the sacrifices and fear. The universe granted that wish in a very 2020 way—wildfires swept the west coast with the same force that the Australian wildfires did way, way back in January of this year. Suddenly, the sky was like something out of Dante’s Inferno, and you could taste the smoke particles floating in the air even through a face mask. The landscape matched the gathering feeling of apocalypse, and new numbers, like 4 million burned acres, joined the statistics we sing ourselves to sleep with: 45.1 million global COVID-19 infections, 230,000 COVID-19 deaths in the United States eight months and counting of using the phrase ‘unprecedented times.’ An article written by Stanford University student Nestor Walters on the wildfires poses the question: “How many more times do we need to hear words like trying, tumultuous or challenging as adjectives to times before we accept that these are simply the times we live in?”

No one can escape it—not the wildfires, not the pandemic, and not climate change. Rozzi, an American pop singer, released a ballad called “Orange Skies” about the wildfires in her hometown of San Francisco. She said of the song, “Despite the massiveness of the issue, I knew I wanted to make the song personal – because of course the underlying issue itself is personal. Climate change isn’t some mythical thing happening to other people, in other places – it’s happening right now, right outside our doors.”

The United Nations Office for Disaster Risk reports 7,348 wildfires, earthquakes, tsunamis, hurricanes, floods, droughts, and heatwaves over the past 20 years. These natural disasters resulted in the deaths of 1.23 million people, affecting a total of 4.2 billion people, and caused $2.97 trillion in global economic losses. Most effected are China and the United States. The report unequivocally links these events to the rising global temperature as a result of greenhouse gas emissions, and finds that any improvements to disaster response or climate adaptation will be “obsolete in many countries” if climate change, the source of the problem, is not immediately addressed.

So how does climate change cause forest fires? National Geographic explains that as temperatures rise due to climate change, the hot air “soaks up water from whatever it touches—plants (living or dead) and soil, lakes and rivers. The hotter and drier the air, the more it sucks up, and the amount of water it can hold increases exponentially as the temperature rises; small increases in the air’s heat can mean big increases in the intensity with which it pulls out water.” In California, the rise in temperature is about 3 degrees Fahrenheit, far above the global average of 1.8 degrees Fahrenheit. The heat combines with parched forest material, which is even dryer due to a persistent drought more intense than any for the past 1,200 years, producing the ideal conditions for a fire to consume forests, in addition to all of the settlements that have increasingly encroached among traditionally undeveloped lands.

Some preventive measures exist, though actual implementation by governments and industry varies. In Australia, nomadic aboriginal groups used to practice surface vegetation burning to prevent outbreaks of fire. Though indigenous populations can no longer engage in that tradition, the method is still emulated by local governments. Urban planning in Australia—where the 2019/2020 season was the hottest on record and driest for 120 years—must prevent expansion into flammable wildland areas, include vegetation-free zones around properties, use fireproof building materials, and plan evacuation and rescue routes in advance. In California, controlled burning of dry brush and excess debris is a common practice, though it contributes to air pollution. Currently, timber companies and biomass industries do not substantially support the state’s fire prevention strategy, so reducing costs of thinning projects would create better incentives for participation on an industry level. Additionally, as in Australia, building codes should emphasize fire-resistance and developing into high-risk areas should be banned. As a whole, these measures could reduce short term damage, but would address only the symptoms of the problem, rather than the problem itself. Unless greenhouse gas emissions are reduced, and the warming of the Earth slows, these practices will not suffice.

Economically, the stakes are high for leaders to respond effectively. California Governor Gavin Newsom announced investments in the CAL FIRE air fleet, early wildfire warning technologies, fire detection cameras, and permanent firefighting positions, along with related crisis counseling, legal services, and housing and unemployment assistance for people affected by the fires. Australian Prime Minister Scott Morrison, on the other hand, was widely criticized for his slow response to the wildfires, though he did expressly link them to climate change—a link that the Australian Finance Minister denied. Though Australia has pledged to reduce its emissions by between 26 and 28% within the next decade, a UN report noted that few of the Conservative government’s policies are designed to reach this target. Studies on the economic impact of wildfires on affected areas show that “large wildfires lead to instability in local labor markets by amplifying seasonal variation in employment over the subsequent year” and that rural areas in particular struggle to recover. Even without the pandemic-induced recession, effects last months and even years in places like rural Oregon. Short term economic gains as local laborers rebuild are overshadowed by the slow economic growth that follows as tourism, logging, and other essential industries drop.

It’s been an overwhelming year, but the pandemic, the wildfires, and climate change are nothing new. We are experiencing the colliding effects of problems we as a global society created and then ignored, until a virus halted civilization and the skies turned orange. The problem isn’t invisible, it’s in everything: it’s the fuel that runs the world we are literally watching burn. But we still have time, just a tiny bit of time, to turn things around, and to lower our emissions by switching to renewable energy, and to rebuild a post-pandemic society sustainably. Nestor Walters puts it best: “We don’t own the past or future; all we have is now. We can’t let hope take away our now, or we’ll find ourselves looking out the window one morning, wondering if the sky used to be blue.”
