Security and crisis management Norway
Vulnerabilities - Norway - Overview
The expected increase in nature-triggered incidents and more extreme incidents will pose several challenges for rescue services and increase the need for coordination. More frequent instances of landslides and flooding will cause challenges for the Civil Defence and rescue services in terms of competence and use of resources. The projected climate changes will also bring challenges for the fire service and the civil defence’s ability to handle the increased risk of forest fires, and for the power industry’s ability to cope with an increase in damage to technical facilities. Furthermore, climate change will pose safety challenges for facilities handling hazardous substances, transportation of hazardous goods and consumer services (35).
An increase in traffic and accessibility in the Northern areas as a result of climate change could increase the accident potential and thus increase the rescue coordination centres’ number of rescue missions. Moreover, an increase in maritime traffic in an ice-free but vulnerable Arctic region could also present more challenges in terms of oil spill preparedness than previously (35).Sovereignty, security, and environmental concerns are likely to arise as marine access increases (36).
Vulnerabilities - Europe – Overview
A very detailed overview on security implications of climate change has been presented by O’Brien et al. (2008) in the report: Disaster Risk Reduction, Climate Change Adaptation and Human Security (1). The implications presented in this report refer to the worldwide situation, not just one country in particular. Unless stated otherwise, the text presented below is a summary of this report.
Climate change, disaster risk reduction and security
Security concerns associated with climate change include the potential for conflict over natural resources, population displacement and migration as the result of sea-level rise or other large-scale biophysical, ecological or social disruptions, and the prospect of increasingly frequent humanitarian disasters as the result of extreme climate events.
Enhancing human security in the 21st century is about responding to climate change and disaster risks in ways that not only reduce vulnerability and conflict, but also create a more equitable, resilient and sustainable future.
The growing recognition that there may be an increasing number of disasters linked to floods, droughts, wildfires and other climate influenced events, coupled with increasing concern over the social implications of climate variability and change, calls for a much deeper and broader assessment of the connections between disaster risk reduction, climate change adaptation and human security.
Thus far, many of the discussions taking place on adaptation to climate change are not well-informed by disaster risk reduction strategies, tools, frameworks and experiences. At the same time, the disaster risk community has not fully incorporated climate change dimensions and information on climate impacts into its work. The risk of more complex, frequent, intense or unpredictable extreme weather events associated with global temperature increases, changing precipitation patterns and sea level rise, coupled with both gradual and non-linear changes to ecosystems and natural resources, suggests the need for a renewed focus on the ways that disaster risk reduction and adaptation can influence the context in which climate change occurs.
Climate change adaptation is defined as:“adjustments in natural or human systems in response to actual or expected climatic stimuli or their effects, which moderates harm or exploits beneficial opportunities” (2).
Records maintained by CRED (3) show that disaster frequency appears to be increasing, from about 100 events per decade in the 1900-1940, to 650 per decade in the 1960s, to 2000 per decade in the 1980s. By the 1990s this number had reached almost 2800 events per decade. The increase in reported disasters can be partly explained by a higher number of small and medium-level events that are related to natural and human-induced or socio-natural phenomena (4). While the number of geophysical disasters has remained fairly steady, the number of hydrometeorological disasters has increased significantly over the last decades (5).
It is estimated that global costs of weather-related disasters alone have increased from an annual average of USD 8.9 billion in 1977-1986 to USD 45.1 billion in the 1997-2006 period (6). According to ICSU about three-quarters of all disasters were triggered by weather-related events during the 1990s, and floods and drought are among the most prominent causes (7). A revised assessment of historical droughts (from 1900 to 2004) concludes that “more than half of all deaths associated with natural hazards are now classified as drought related, and only floods rank higher in terms of the number of people affected.” (8).
Mortality due to climate change is very likely to increase further through a range of direct effects (such as more intense heat waves, floods, and fires), indirect effects (such as declines in water quality and food security, and changes in disease vectors), and through social and economic disruptions (such as increased poverty and migration) (9). Climate change is likely to exacerbate the incidence of infectious diseases such as malaria, waterborne diseases such as diarrhea and cholera, and cardio-respiratory diseases. ERM estimated that even in the 1990s, some 35-40 percent of the worst disasters had a strong climate change signal, thus these statistics on losses are likely to increase in the absence of proactive climate change adaptation and disaster risk reduction (10).
Vulnerabilities - Urbanization
Recent research attention has also emphasized the linkages between rapid urbanization and disasters (11). Urbanization has become the dominant feature of human settlement patterns over the past century. More than half of the world’s current population lives in cities. By the year 2015 there are expected to be 60 megacities in the world, each with a population of 10 million or more people. Over the next several decades, the largest urban population changes are expected to occur in coastal areas, particularly in Asia and Africa (11).
The linkages between rapid urbanization and disasters have sometimes been described as reflexive: cities create their own risks by causing degradation of the local, regional, and global environments. High concentrations of resources and people within cities also mean that the economic, social, and environmental costs of extreme events are high in urban areas. Furthermore, these costs are likely to escalate as a result of growing populations in coastal cities, many of which are already highly vulnerable to sea-level rise, tsunamis, and other hazards.
Vulnerabilities – Mortality and damage
The private sector and their associated investments are also directly threatened by climate change. Ernst & Young describe climate change, coupled with its potential destabilizing affects linked to conflict and security, as the “greatest strategic risk facing the property and causality insurance industry” (12).
Concerning the economic and financial consequences of extreme events, many studies have explored the local and regional economic impacts of specific events, such as hurricanes, floods, earthquakes, heat waves, and wild fires. This research is generally focused on aggregate impacts including costs of business interruption, infrastructure damage and loss of business structures and productive capital, as well as on measures to reduce economic risks such as broader provision of private insurance, enforcement of building codes, and development of disaster preparedness plans. Limited attention has been directed toward the effects of extreme events on industries, businesses, and workers, including which industries are likely to expand or contract, which firms are likely to survive, and which types of workers are likely to gain or lose jobs.
Climate change may have a number of indirect effects as well. These may arise, for example, through changes in the costs of essential goods and services. Increasing water scarcity may lead to an increase in water prices; warmer temperatures are likely to influence demand for and the cost of energy for cooling; and climate-induced changes in the agricultural sector may drive up food prices. As with the direct effects of climate change, indirect effects will be unevenly distributed, with the burden falling most heavily on low-income households where a significant share of expenditures already goes towards food and energy, and where the opportunity costs of increased spending in these areas may lead to declining access to goods and services necessary to live dignified lives. Labor markets may also be affected, for example if production decreases associated with drought lead to a reduced demand for agricultural wage laborers.
Physical versus social vulnerability
A “physical vulnerability” approach emphasizes biogeophysical and technological interpretations that relate vulnerability to locations in high-risk areas (e.g., low-lying coastal areas), high concentrations of population and physical capital in small areas, a dependency on large-scale infrastructure projects, an increased risk of disease transmission due to crowded conditions, and location in fragile or vulnerable environments, such as deforested mountain slopes (13). This hazard-centered or impact-oriented paradigm focuses largely on the physical processes underlying vulnerability to climate change and disasters. Consequently, vulnerability reduction strategies often seek to control outcomes through monitoring and predicting, as well as through engineering projects and technological interventions that contain or reduce their effects (14).
A “social vulnerability” approach, in contrast, focuses on vulnerability as the result of an interplay among many contextual factors, including biophysical, social, economic, political, institutional, technological and cultural conditions that generate unequal exposure to risk and create differential capacities to respond to both shocks and long-term changes (15).
An individual or group’s vulnerability to climate change and climate-related disasters is thus influenced by the complex array of social, economic, political and environmental factors operating at a variety of levels that in combination affect vulnerability. Consequently, vulnerability is not evenly distributed across society, and some individuals, households, or groups are likely to be disproportionately affected by climate change or disasters.
In short, the possible effects of climate change extremes cannot be understood independently of larger social, economic and cultural changes. It is widely recognized within the disaster risk community that hazards themselves rarely create disasters, but instead it is the context in which the hazard occurs that contributes to disastrous outcomes (16).
This is relevant to climate change-related extreme events as well. Yet it is also important to recognize that the context in which climate extremes and hazards occur is constantly changing as the result of many factors, including rates of economic development and natural resource exploitation, urbanization, deforestation and land use changes. Among the many environmental and social processes that structure vulnerability, rising global food prices, warfare, corruption, trade dependency, macroeconomic policies, and a host of large-scale processes associated with globalization shape the social and economic entitlements that influence vulnerability (17).
There are also important path dependencies related to vulnerability; past processes such as colonization and war shape present insecurities, while ongoing processes such as climate change and changes to ecosystem services shape future insecurities.
Hazards and extreme events themselves can alter the context for economic and social development, which can in turn reduce the capacity to respond to future extremes. Cumulative effects of events such as hurricanes, floods, or droughts not only damage or destroy material assets and human lives, but they may also influence the capacity and resilience of individuals to recover their sense of well-being. Common emotional reactions after a disaster include shock, fear, grief, anger, guilt, shame, helplessness, numbness and sadness, which in combination with cognitive reactions such as confusion, indecisiveness, worry and difficulty concentrating, can make recovery a challenge for days, weeks, months, or years following a disaster.
Vulnerabilities - According to the IPCC
In 2012 the IPCC published a special report on Managing the Risks of Extreme Events and Disasters to Advance Climate Change Adaptation. Key findings in this report with respect to human security are summarized below (40).
Estimates of the numbers of current and future migrants due not only to disasters but generally to environmental change are divergent and controversial (41). A middle-range estimate puts the figure at 200 million by 2050 (42). Looking only at extreme weather as a cause of migration, a recent report estimates that over 20 million people were displaced due to sudden onset climate-related disasters in 2008 (43). This report and others, however, acknowledge the difficulty of disentangling the drivers of migration, including climate change risks, rising poverty, spread of infectious diseases, and conflict (44).
The relationship between climate risk and displacement is a complex one and there are numerous factors that affect migration (45). Nonetheless, recent research suggests that adverse environmental impacts associated with climate change have the potential to trigger displacement of an increased number of people (46). Studies suggest that most migration will take place internally within individual countries; that in most cases when climatic extremes occur in developing countries they will not lead to net outmigration because people tend to return to re-establish their lives after a disaster; and that while long-term environmental changes may cause more permanent migration this will also tend to be internal (47).
Attention has been mainly focused on population displacement associated with large disasters. However, the compound effect of smaller, more frequent events can also contribute to displacement. It is estimated that such extensive disasters account for an additional 19% displacement of people who are typically less visible than those displaced in larger events that attract international media and humanitarian assistance (48).
Concerns on the security implications of climate change range from increased needs for humanitarian assistance to concerns over environmental migration, emergent diseases for humans or in food chains, potentials for conflict between nations or localities over resources, and potential for political/governmental destabilization due to climate-related stresses in combination with other stresses, along with efforts to assign blame (49).
Climate change is generally regarded to act as a threat multiplier for instability in some of the most volatile regions of the world (50).
Vulnerabilities - According to the European Commission
Since the EU’s neighbours include some of the most vulnerable regions to climate change, e.g. North Africa and the Middle East, migratory pressure at the European Union's borders and political instability and conflicts could increase in the future. The European Commission published a paper that enumerates all the threats driven by climate change and related in one way or another to security issues (37):
- Conflicts over diminished resources: shortage of water, reduction of agricultural land, increased flooding and longer droughts may lead to economic losses and increased food prices. The overall effect is that climate change will fuel existing conflicts over depleting resources, especially where access to those resources is politicised.
- Economic damage and risk to coastal cities and critical infrastructure: Mega-cities, with their supporting infrastructure, such as port facilities and oil refineries, are often located by the sea or in river deltas. Sea-level rise and the increase in the frequency and intensity of natural disasters pose a serious threat to these regions and their economic prospects. The East coasts of China and India as well as the Caribbean region and Central America would be particularly affected. An increase in disasters and humanitarian crises will lead to immense pressure on the resources of donor countries, including capacities for emergency relief operations.
- Loss of territory and border disputes: Receding coastlines and submergence of large areas could result in loss of territory, including entire countries such as small island states. A further dimension of competition for energy resources lies in potential conflict over resources in Polar regions which will become exploitable as a consequence of global warming. Desertification could trigger a vicious circle of degradation, migration and conflicts over territory and borders that threatens the political stability of countries and regions.
- Environmentally-induced migration: Europe must expect more migration from its neighbouring and more vulnerable countries.
- Situations of fragility and radicalization: Climate change may significantly increase instability in weak or failing states by over-stretching the already limited capacity of governments to respond effectively to the challenges they face.
- Tension over energy supply: Intensified competition over access to, and control over, energy resources is, and will continue to be, a cause of instability. There is a possibility of greater energy insecurity and greater competition for resources. As previously inaccessible regions open up due to the effects of climate change, the scramble for resources will intensify.
- Pressure on international governance: Climate change impacts will fuel the politics of resentment between those most responsible for climate change and those most affected by it. Impacts of climate mitigation policies (or policy failures) will thus drive political tension nationally and internationally.
Vulnerabilities - According to the German Advisory Council on Global Change
Climate-induced conflict constellations
The German Advisory Council on Global Change (WGBU) made an assessment on global security risks of climate change (38). WBGU considers that climate-induced inter-state wars are unlikely to occur. However, climate change could well trigger national and international distributional conflicts and intensify problems already hard to manage such as state failure, the erosion of social order, and rising violence. WBGU identifies four conflict constellations in which critical developments can be anticipated as a result of climate change and which may occur with similar characteristics in different regions of the world. “Conflict constellations” are defined as typical causal linkages at the interface of environment and society, whose dynamic can lead to social destabilization and, in the end, to violence.
- Climate-induced degradation of freshwater resources. 1.1 billion people are currently without access to safe drinking water. The situation could worsen for hundreds of millions of people
- Climate-induced decline in food production.More than 850 million people worldwide are currently undernourished. This situation is likely to worsen in future as a result of climate change, due to a drop in agricultural productivity, desertification, soil salinization and water scarcity.
- Climate-induced increase in storm and flood disasters.The risk of natural disasters occurring in many cities and industrial regions in coastal zones will be further amplified by deforestation along the upper reaches of rivers, land subsidence in large urban areas and the ever greater spatial concentration of populations and assets.
- Environmentally-induced migration.It can be assumed that the number of environmental migrants will substantially rise in future due to the impacts of climate change. Most environmental migration is initially likely to occur within national borders. Transboundary environmental migration will mainly take the form of south-south migration, but Europe and North America must also expect substantially increased migratory pressure from regions most at risk from climate change.
Six threats to international stability and security
In light of current knowledge about the social impacts of climate change, the German Advisory Council on Global Change (WGBU) identifies the following six key threats to international security and stability which will arise if climate change mitigation fails (38):
- Possible increase in the number of weak and fragile states as a result of climate change.
- Risks for global economic development.Unabated climate change is likely to result in substantially reduced rates of growth. This will increasingly limit the economic scope, at national and international level.
- Risks of growing international distributional conflicts between the main drivers of climate change and those most affected.A key line of conflict in global politics in the 21st century would divide not only the industrialized and the developing countries, but also the rapidly growing newly industrializing countries and the poorer developing countries. The international community is ill-prepared at present for this type of distributional conflict.
- The risk to human rights and the industrialized countries’ legitimacy as global governance actors.Unabated climate change could plunge the industrialized countries in particular into crises of legitimacy and limit their international scope for action.
- Triggering and intensification of migration.The associated conflict potential is considerable, especially as “environmental migrants” are currently not provided for in international law.
- Overstretching of classic security policy.A climate-induced increase in the number of weak and fragile states or even the destabilization of entire sub regions would overstretch conventional security policy.
Definition of water security according to the UNDP
Water security is about ensuring that every person has reliable access to enough safe water at an affordable price so as to lead a healthy, dignified and productive life, while maintaining the ecological systems that provide water and which also depend on water. If these conditions are not met, or if access to water is disrupted, people face acute human security risks transmitted through poor health and the disruption of livelihoods. Sufficient, safe, acceptable, physically accessible and affordable water for personal and domestic use are the five core attributes that represent the foundations for water security (39).
Adaptation strategies - According to the European Commission
According to the European Commission (37), the EU should focus on:
- Enhancing capacities at the EU level: build up knowledge and assess the EU's own capacities, followed by an improvement in the prevention of, and preparedness for early responses to, disasters and conflicts. Monitoring and early warning needs to include in particular situations of state fragility and political radicalisation, tensions over resources and energy supplies, environmental and socio-economic stresses, threats to critical infrastructures and economic assets, border disputes, impact on human rights and potential migratory movements.
- EU multilateral leadership to promote global climate security: the EU needs to continue and strengthen its leadership towards an ambitious post-2012 agreement in 2009, including both mitigation and adaptation action by all countries as a key contribution to addressing climate security.
- Cooperation with third countries: greater prioritisation and enhanced support for climate change mitigation and adaptation, good governance, natural resource management, technology transfer, trans-boundary environmental cooperation (inter alia water and land), institutional strengthening and capacity building for crisis management.
Adaptation strategies - According to the German Advisory Council on Global Change
According to the German Advisory Council on Global Change (WGBU) a number of initiatives are needed (38):
- Shaping global political change.In order to ensure the acceptance and, above all, the constructive participation of the ascendant new world powers China and India, a multilateral order is needed which is viewed as fair by all countries.
- Reforming the United Nations.In general, WBGU is in favour of better coordinating the efforts of the relevant organizations and programmes under the auspices of the UN and significantly enhancing their role in the interests of prevention.
- Ambitiously pursuing international climate policy.WBGU recommends the adoption, as an international standard, of a global temperature guard rail limiting the rise in near-surface air temperature to a maximum of 2°C relative to the pre-industrial value.
- Implementing the energy turnaround in the EU.In order to be a credible negotiating partner within the climate process, the European Union should achieve its Kyoto commitments and set more far reaching and ambitious reduction targets for the future. In WBGU’s view, a 30 % reduction target for greenhouse gas emissions by 2020 compared with the 1990 baseline and an 80 % reduction target by 2050 are appropriate.
- Developing mitigation strategies through partnerships. In development cooperation, path dependencies of emissions-intensive technologies should be avoided, and high priority should be granted to the promotion of sustainable energy systems in order to overcome energy poverty.
- Supporting adaptation strategies for developing countries.Adapting water resources management to climate change and avoiding water crises, a.o. in order to avoid water conflicts, cooperation on transboundary water management should be encouraged for regions sharing waters. Focus should also be on gearing agriculture to climate change.
- Stabilizing fragile states and weak states that are additionally threatened by climate change. Crisis prevention costs far less than crisis management at a later stage. Specifically, fragile states’ capacities to manage environmental risks must be maintained and reinforced, and if necessary re-established, even under difficult political and economic conditions.
- Managing migration through cooperation and further developing international law.
- Expanding global information and early warning systems.Both the gradual changes caused by climate change and the natural disasters which are expected to occur with increasing frequency could destabilize the affected regions and, in extreme cases, constitute a major risk factor for national and international security. Global information and early warning systems can therefore do much to mitigate these adverse effects and make a major contribution to conflict and crisis prevention.
WBGU anticipates that in the event of mitigation efforts failing, climate-induced security risks will begin to manifest themselves in various regions of the world from around 2025–2040. The key challenge is to take resolute climate policy action within the next 10–15 years, in order to avert the socioeconomic distortions and implications for international security that will otherwise intensify in subsequent decades (38).
Adaptation strategies - Vulnerability reduction
Vulnerability reduction is thus recognized as an important strategy for reducing disaster risks and minimizing the impacts of climate change. However, despite increased emphasis on the importance of social, political and economic contexts, climate change adaptation and traditional disaster risk management activities remain largely delinked from vulnerability reduction (18).
In fact, a synthesis of evaluation findings on humanitarian responses to natural disasters found relatively few examples of good practices related to vulnerability reduction (19). There tends to be, instead, a disproportionate emphasis on relief and recovery processes that prioritize a return to ‘normalcy,’ rather than focusing on the conditions that cause risk and vulnerability. In many cases, these ‘normal’ conditions are directly or indirectly contributing to risk and vulnerability (20).
Given these overlapping areas of expertise and empirical experience, there have been numerous calls for increased collaboration between the two communities. Yet strategies for disaster risk reduction and climate change adaptation have until now evolved largely in isolation from each other through different conceptual and institutional frameworks (21).
The disaster risk management community has gone through paradigm shifts from managing disasters by addressing the hazards, to understanding and addressing the underlying factors and vulnerabilities that turn hazards into disasters, culminating in the disaster risk reduction framework (22). The Hyogo Framework for Action (HFA) was adopted by 168 countries in 2005, and provides a technical and political agreement on the areas that needs to be addressed to reduce risk. The HFA presents five priorities for action:
- ensure that disaster risk reduction is a national and a local priority with a strong institutional basis for implementation;
- identify, assess and monitor disaster risks and enhance early warning;
- use knowledge, innovation and education to build a culture of safety and resilience at all levels;
- reduce the underlying risk factors;
- strengthen disaster preparedness for effective response at all levels.
Climate change adaptation has a somewhat shorter history, emerging in the United Nations Framework Convention on Climate Change (UNFCCC) signed in 1992. However, the UNFCCC and the Kyoto protocol predominantly addressed climate change mitigation and policies and measures to reduce the emissions of greenhouse gases. It was not until quite recently that adaptation came to the forefront as a key concern within the UNFCCC (23). The Bali Action Plan (BAP), agreed upon at the UNFCCC Conference of Parties (COP) in Bali, puts adaptation on an equal footing with mitigation.
Disaster risk reduction and climate change adaptation must be closely linked to development
Enhancing collaboration across the disaster risk, climate change and development communities may be the most effective means of promoting sustainable adaptation to climate change. … Risk reduction and adaptation strategies must be carefully tailored to individual, household and community needs. Approaches that treat communities as homogeneous (i.e., able to adapt or reduce risks as a group) are prone to failure, as are adaptation and disaster risk reduction measures that do not explicitly and simultaneously address poverty (24).
Disaster risk reduction and climate change adaptation must address local needs
Engagement at the community level is underpinned by a reframing of vulnerable people not as passive victims but as capable of preventing disasters and adapting to climate change within their own communities. Bottom-up approaches promote locally-appropriate measures, empower people to change their own lives, and encourage greater ownership of disaster risk reduction and adaptation actions. Communications have been highlighted as extremely important, which suggests an emphasis on presenting knowledge in a community’s own language, through innovative media, and in understandable non-scientific terms.
Climate information must capture complexity and uncertainty to support adaptation and disaster risk reduction
Currently, the spatial resolution of many climate change projections is too coarse to enable effective disaster risk reduction at the local or regional scale. The gap between climate forecasts and projections and the needs of resource managers may pose some challenges to effective responses. … There is a need for a better understanding of complex and compound hazards, both from physical and social perspectives. The complexity of future extreme events, which are likely to be characterized by one or more hazard that is compounded by other factors (e.g. flooding combined with a cholera outbreak that coincides with an economic crisis), requires more robust and flexible disaster risk strategies and institutional responses than has been typically used in the past. … Communication about climate change needs to be made accessible in order to engage vulnerable people without compromising scientific credibility (25).
There are thresholds and limits to disaster risk reduction and adaptation
There are likely to be some thresholds and limits to the potential for disaster risk reduction and adaptation to enhance human security in the face of climate change. It has been noted that “the risk-reducing potential of planned adaptation is either very limited or very costly for some key vulnerabilities, such as loss of biodiversity, melting of mountain glaciers or disintegration of major ice sheets” (26)
In other words, there are absolute limits that are faced by many ecosystems and individual species in adapting to new climatic conditions, particularly given constraints of urban land use and conversion of natural habitats to agriculture; over-exploitation of resources such as fisheries; and other stresses such as pollution loading to terrestrial and marine environments (27). Hence there are major non-linearities and uncertainties related to climate change.
It is argued that “adaptation assessments need to consider not only the technical feasibility of certain adaptations but also the availability of required resources, the costs and side effects of adaptation, the knowledge about those adaptations, their timeliness, the incentives for the adaptation actors to actually implement them, and their compatibility with individual or cultural preferences” (26). Six broad categories have been discussed of limits to adaptation closely linked to the rate and magnitude of climate change, as well as associated key vulnerabilities: physical and ecological limits, technological limits, informational and cognitive limits, social and cultural limits, institutional political limits, and financial limits (28).
Adaptation - Costs
Financial barriers to both adaptation and disaster risk reduction have been highlighted, but primarily in policy documents around the international climate regime, rather than in scientific and economic literatures. The SBSTA body of the UNFCCC, the Stern Review, the World Bank, OECD, Oxfam and UNDP have estimated adaptation costs for developing countries (29).
The Stern Review presents the lowest estimate of USD 4 billion per year to adapt to climate change. The highest estimate is made by UNDP which estimates adaptation costs to USD 86-109 billion a year. An OECD study on the economics of adaptation demonstrates that these numbers, which have already been widely used in political statements and demand for more funds, should be handled with caution (30). … The important point is that the costs of adaptation are significant and hence there are real financial barriers, especially in developing countries, to implementing adaptation in a sustainable manner.
Climate change and migration
Recent studies suggest that climate change and associated adverse environmental impacts have the potential to trigger displacement of an increased number of people. Research further suggests that
- the bulk of migration will take place internally in individual countries;
- the majority of migration will come as a result of gradual changes in climate and not so much from individual catastrophic events;
- in most cases when hydro-climatic disasters occur in developing countries they will not lead to net out-migration because people tend to return to re-establish their lives after a disaster;
- long term environmental changes are likely to cause more permanent migration (31).
Recent studies (31) distinguish between migration driven by
- the increasing frequency and intensity of slow onset disasters such as drought and desertification;
- rapid onset disasters such as floods and cyclones, and
- incremental changes driven by sea-level rise.
Most studies agree that the most important climate change-related driver of migration will be sea-level rise, with the more careful assessments recognizing that the severity of migration will depend critically on the rate of localized changes in sea-level, and the degree to which adaptation takes place and is successful (32). These studies also recognize that the rate of migration driven by sea-level rise is likely to be slow, but steady, which suggests that disaster risk reduction and adaptation strategies may help avoid humanitarian crises and political instability.
Some studies also recognize that there may be some degree of exaggeration surrounding discussions of “environmental refugees” driven by climate change, creating the danger of inappropriate policy responses that do little to ensure the rights of those most at risk from climate change (33). While it does seem likely that climate change will be an additional contributor to migration, many studies emphasize that it is very unclear how many migrants there may be, where they may move from and to, and over what time scale. … It is also widely recognized that environmental change is never a sole cause of migration, and that there are always one or more underlying economic, political or other social factors that make environmental change a proximate trigger, rather than an underlying driver of migration.
Climate change and conflict
Many studies do indicate the possibility of a connection between climate and conflict, and justify grounds for concern about the possibility that climate change may increase the risk of violent conflict. … It is also important to recognize that conflicts resulting from climate change will not necessarily be violent and can instead lead to changes in the distribution of power and resources, and protection of the things that are valued. Furthermore, research on international river basins shows that issues of water access and water scarcity in many cases lead to cooperation, rather than conflict (34). In short, the evidence about the links between environmental change and violent conflict is currently inconclusive.
