Lake Chad - Interstate Conflicts and Cooperation
Between 1963 and the present day, the surface of Lake Chad has shrunk by 50%. In the context of increasing environmental change, long-term stability requires the cooperation of the co-riparians to elaborate sustainable strategies to manage the basin region.
Conceptual Model

Climate Change

Lake Chad, shared by Nigeria, Niger, Chad, and Cameroon, has shrunk by 50% compared to its 1963 level, partly due to more frequent and severe droughts as well as decreasing average rainfall.

Intermediary Mechanisms

As a consequence, the basin’s natural resources have become increasingly scarce, with severe consequences for dependent local communities, who have begun competing over land and water. Moreover, the diversion of the lake’s waters has sparked several conflicts among co-riparians over water, fish, and land resources.

Fragility and Conflict Risks

Several, sometimes violent, interstate conflicts have ensued as a consequence of the lake’s natural resource depletion. The most notable disputes are a conflict between Cameroon and Nigeria over the Bakassi Peninsula, as well as a conflict between Nigeria and Chad over the status of new islands that had emerged, which caused 84 fatalities.

Conflict History

Lake Chad - which straddles Cameroon, Chad, Niger and Nigeria - is one of the largest lakes in Africa, as well as a vital ecosystem for approximately 35 million people living around its basin. The combination of large irrigation projects and environmental change has been responsible for the depletion of the lake, which has shrunk by 50% compared to its 1963 level (Hendrix, 2014).

As the lake started to recess, the four riparian states formed the Lake Chad Basin Commission (LCBC) in 1964 in order to effectively manage the lake’s waters and foster cooperation at the regional level. However, despite these measures, the LCBC’s weak institutional mechanisms were not able to prevent the member states from pursuing unilateral projects in the lake region. These unilateral initiatives led to tensions, which escalated to conflicts at several occasions.

Today, violent conflicts between states have been settled due to external bodies and the co-riparians collaborate on several restoration projects with the support of a number of international organisations. Nevertheless, despite these projects, weaknesses in the LCBC institutions remain and tensions still persist between the member states.

Partial cooperation and competition over water
In 1964, after signs had become visible that Lake Chad was waning, the four riparian states of the lake created the Lake Chad Basin Commission (LCBC) (FES, 2011). This was considered a cooperative success (Oregon State University, 2011), which demonstrated the willingness of the co-riparian states to address the ecological challenges of the basin (Bächler and Spillmann, 1996). Several mechanisms were put in place to ensure effective management of the lake, including the obligation of member states to inform the commission prior to conducting projects (Ibid.). Throughout the 1970s, further instruments were created to reinforce the institutions of the LCBC (FES, 2011).

Despite these efforts, the LCBC’s institutions have remained weak (Ibid.). The absence of international monitoring and sanctioning bodies (Odada et al., 2006) as well as loopholes in the agreement between the co-riparian states (Bächler and Spillmann, 1996) have deprived the Commission of any power to enforce the LCBC’s mechanisms. Moreover, the member states never reached any agreement on water allocation (Ibid.) nor did they harmonize their national water policies (Metz, 2007).

After the region was hit by severe droughts in 1972, the co-riparian states initiated national hydrological projects to be able to cope with future climatic shocks (Bächler and Spillmann, 1996). However, the member states did not comply with the obligation to inform the LCBC beforehand. Nigeria initiated the South Chad Irrigation Project in 1973; Cameroon constructed dams on the Chari-Logone River – a main tributary to the Lake – “in obvious violation of the treaty provisions”(Ibid.), whilst Niger constructed dams on the bank of the Komadougou-Yobe River (Odada et al., 2006). At the beginning of these projects, water diversion was minimal, but started to increase betwen 1982 and1985 (Bila et al., 2014). During this period, the volume of diverted water accounted for nearly 50% of the lake's decrease in surface (Metz, 2007).

Disputes between co-riparian states
As the co-riparians increasingly diverted the lake’s waters, several conflicts over water, fish and land resources emerged during the 1980s and the 1990s (Bila et al., 2014). The most salient inter-state disputes, which happened during this period, are a conflict between Cameroon and Nigeria over the Bakassi Peninsula – which was settled by the International Court of Justice – as well as a conflict between Nigeria and Chad over the status of new islands that had emerged as a consequence of the lake’s recession, which caused 84 fatalities (Ibid.).

Unilateral water projects have worsened the environmental situation
Moreover, by erecting improperly-designed dams and reservoirs and conducting uncoordinated operations – in pursuit of their narrow national interests – the riparian states have aggravated the consequences of increased droughts and decreasing rain falls on lake depletion (Odada et al., 2006; Onuoha, 2010). As a consequence, the basin’s natural resources have become increasingly scarce, with severe consequences for local communities, who depend on them (Onuoha, 2010). This has led to increased competition and conflicts over land and water, which have not yet been solved (see Lake Chad - Local Conflicts over Livelihood and Survival Resources).

Resolution Efforts

Restoration of Stability
As of today, violent disputes amongst the co-riparian states of the Lake Chad have been settled with the support of international bodies, such as the International Court of Justice (ICJ) in the case of the conflict over the Bakassi peninsula (ICE, 2005). Even though tensions between states have not disappeared – for instance Nigeria still contests the decision of the ICJ today (Metz, 2007) – the many organisations involved in the restoration of Lake Chad, such as UNEP, WWF, FAO and the World Bank, have been key in achieving more stable diplomatic relations between the co-riparian states (Asah, 2015), but also in promoting basin-wide cooperation to prevent a further degradation of Lake Chad (Odada et al., 2006; FES, 2011).

Awareness of the necessity to act
Since the beginning of the 2000s, growing awareness of the urgent need to protect and restore Lake Chad have led the co-riparian states and the LCBC to engage in a number of joint water management initiatives with the support of a number of international organisations (Odada et al., 2006; Onuoha, 2010). These include a major project to transfer the waters of the Congo basin (Oubangui) to Lake Chad in order to replenish the lake (Onuoha, 2010) and a sustainable development programme for Lake Chad, which was launched in 2009 (FES, 2011). Moreover, frequent meetings between the LCBC members (Ibid.) and the improved commitment of the latter to their financial obligations towards the Commission indicate that the co-riparians’ political will to cooperate has greatly improved (Odada et al., 2006).

Obstacles to the implementation of restoration projects
Nevertheless, despite these signs of cooperation, reports have pointed out that the riparian states have failed to implement several projects initiated by the LCBC (Metz, 2007). In 2011, for instance, an assessment of the progress of the sustainable development programme for Lake Chad pointed out that only 15% of the programme's activities had been implemented (FES, 2011).

In fact, several factors are still hindering the implementation of restoration projects in the Lake Chad region. First, there is a clear lack of personnel and experts at the national and regional level (Ibid.). Second, international agencies involved in restoration projects often fail to effectively coordinate the work of their regional partners. This has led to important delays, as in the case of the Lake Chad GEF PDF-B project - originally planned to last eight months, the implementing agencies –World Bank, UNDP and UNEP– took three years to develop a report (Odada et al., 2006). Finally, the increasing threat of Boko Haram in the region is a major obstacle to the technical implementation of projects, such as the Oubangui transfer project, as the presence of the group makes it impossible to safely send technicians and experts on the ground (Galy, 2014).

Weaknesses of the LCBC
These problems are further compounded by important loopholes in the mechanisms of the LCBC, which hamper continuous and sustainable cooperation between its members. Experts, therefore, point out the necessity for the member states to harmonise their water policies (Metz, 2007) and to agree on clear water allocation rules (Odada et al., 2006). The FAO is currently assisting the LCBC in studying water allocation options (Ibid.). Furthermore, creating monitoring and sanctioning mechanisms, thereby making agreements enforceable, is critical to guarantee that member states will comply to the rules set by the Commission (Ibid.). In fact, agreements amongst the co-riparian states have only been voluntary so far, and, therefore, have often failed (Ibid.) Finally, it is critical to endow the LCBC with the necessary power to settle conflicts between member states - the LCBC was unable to settle the conflict over the Bakassi Peninsula, for instance. This is critical as tensions between member states have not completely disappeared.

Other possible sources of inter-state tensions
Further factors, such as the presence of Boko Haram in the Lake Chad region, are a source of tensions between co-riparians states (Asah, 2015). Moreover, as climate change continues to erode the lake's resources, new tensions over water allocation could emerge (Ibid.).

To conclude, it is clear that projects to restore the lake must be combined with a strengthening of the LCBC. In particular, cooperation could be strengthened by clarifying water allocation rules amongst the LCBC member states. The LCBC Commission has in fact already taken an important step in this direction by requesting the FAO to support it in assessing different allocation options. Yet, new water regulations will also need to take into account the possible impacts of climate change on the Lake's resources. Given these challenges, international organisations involved in projects in the Lake Chad region will continue to play an important role in fostering sustainable water management and promoting cooperation between co-riparian states.

Adaptation & Resilience

All countries will need to adapt to some of the environmental, social and economic impacts of climate change that are already unavoidable. Food security, livelihoods, water resource availability and public health are some affected areas. People living in poverty are more vulnerable, having a lower capacity to adapt. Thus, it is essential to promote resilience building. The adaptation and resilience aspects need to be mainstreamed into planning by policy makers and the private sector as well as integrated into development strategies.

Biodiversity & Livelihoods

Nature protection is most sustainable if it essentially contributes to the long-term stability of human needs. Today many regions around the world are confronted with increasing destruction of the natural foundations of life. The consequences of wide-ranging resource destruction are no longer regionally limited, but rather represent a global threat. Those affected are mainly rural populations, who find the sources of their income and the foundations of their way of life swept away. The depletion and destruction of natural resources goes hand in hand with decreasing agricultural yields and increasing poverty, which in turn forces the affected populations to deplete the remaining resources.

Capacity Building

On the one hand, conflicts are caused by structural factors, such as economic and social inequality or environmental destruction. On the other hand, conflicts are fuelled by a lack of democratic structures, deficient mechanisms of non-violent conflict settlement, inadequate rule of law, the destruction of social and cultural identity and the disregard of human rights. Against this backdrop, development policies have been dedicated to a broad concept of security, which comprises political, economic, ecological and social stability. As a consequence, development cooperation agencies and actors have developed a broad spectrum of approaches for conflict prevention and transformation as well as for sustainable use of natural resources.

Sorry, no description found.

Civil Society

Civil society is the first victim of environmental pollution, under-development and conflicts. Economically disadvantaged and politically marginalized population groups are particularly affected by violent conflicts as well as increasing resource degradation. Simultaneously, civil society is a fundamental pillar for implementing sustainable development. It contributes in many ways to strengthening conflict prevention and plays a significant role in the peaceful and democratic development of states. It must be supported to strengthen civil rights, adherence to human rights in general and democratic participation.

Climate Change

Climate change resulting from the emission of greenhouse gases represents one of the vital challenges for international environmental policy. Flooding, droughts, shifting of climate zones and increasingly frequent and intense extreme weather events will have serious economic and social consequences for entire regions. The climate problem is also directly linked to the question of future energy generation.

Climate Diplomacy

To address the challenges posed by climate change, a new profile of climate diplomacy is evolving. This utilises a full range of policies, including development cooperation, conflict prevention efforts, and humanitarian assistance, in addition to more traditional measures of climate change adaptation and mitigation. Moving from a risk analysis of climate-related threats to well-timed preventive action requires a greater commitment to integrating climate change concerns into development, foreign, and security policies. Examples include strengthening diplomatic networks, building new alliances with partners, and raising awareness – not only of potentially negative climate change impacts, but also of opportunities to embark on a sustainable transformation of our societies.

Climate action entails an array of economic, social, political and environmental co-benefits. It provides an opportunity for economic growth and new jobs. Many investments can take into account climate considerations without becoming more costly. Further important co-benefits include: improved energy security, less local air and water pollution, health benefits as well as ecosystem and biodiversity protection.

Conflict Transformation

In order to overcome the structural causes of violent conflicts and thus bring about an improvement in the framework conditions for peaceful and fair development, it is essential to have long term and broadly planned peace development and peace advancement. Various governmental and non-governmental, national and international actors and groups are involved in these processes.

Climate change and development are inextricably linked. Climate change endangers the development agenda and has the potential to reverse development goals. Furthermore, successful mitigation of climate change heavily depends on development choices around the world. Therefore, development strategies need to be climate-compatible to provide long-term success, and there are viable policy options that support this compatibility. Many mitigation and adaptation activities can present development opportunities to developing countries and avoid the lock-in to environmentally damaging technologies.

Early Warning & Risk Analysis

The reasons for the development and escalation of conflicts and the incidence of risks are multifaceted and complex. Simultaneously, the assessment of the specific causes in the form of risk and conflict analyses can contribute to a better understanding of these processes and make it possible to provide warning of negative developments, or ideally help prevent them. In the context of natural resource use, risks and conflicts have gained increasing attention in the past years. The debate on possible future water wars is merely one example.

The well-being of individuals, communities and nations depends on the availability of energy resources. The gap between energy supply and demand appears to be growing, making the world vulnerable to serious economic shocks. At the same time, the burning of fossil fuels causing climate change is one of the vital challenges of international environmental policy. So far, only rudimentary approaches exist for shaping climate and energy security in a sustainable way. The components of a strategy that can contribute to reducing vulnerabilities related to climate change and energy policy include a greater role for renewable energies, the improvement of energy efficiency and a stronger decentralisation of energy supply.

Environment & Migration

The economic, social and environmental consequences of climate change aggravate the breakdown of eco-system-dependent livelihoods and are likely to become dominant drivers of long-term migration. Natural disasters already cause massive shorter-term displacement and the number of temporarily displaced people is likely to further increase with climate change. For vulnerable populations in vulnerable regions, such as the Sahel zone or the Ganges delta, migration often becomes the sole survival strategy. In order to address climate-related displacement and migration successfully, knowledge of effective adaptation and an improved understanding of how environmental change affects human mobility is essential.

Climate finance, from all sources, plays a key role in supporting and enabling adaptation and mitigation action as well as climate and energy innovation. The Paris Agreement ensured that the Green Climate Fund and the Global Environment Facility are at the core of climate finance architecture as entities entrusted with the operation of the Financial Mechanism of the UNFCCC. Increasing climate finance from all relevant public and private sources is crucial. Furthermore, much needs to be done to redirect finance flows to sustainable paths, e.g. reducing fossil fuel subsidies, introducing maritime and air transportation taxes. The conditions for green investment in developing countries should also be improved.


Forests are disappearing at an alarming rate. Competition for forest resources triggers, exacerbates, or finances numerous crises and conflicts in tropical developing countries. Illegal logging and timber trade foster instability and sometimes violent conflict by strengthening illegal and armed groups, increasing corruption and exacerbating use and claim conflicts among local communities, the state and the business sector. Forests are a vital resource to poor people but they can also become areas of conflict. Sustainable management of forest resources is therefore key to preventing violent conflict over and within forests.

Gender plays an important role as a category of conflict for many reasons. The interlinkages between gender, environment and conflicts are complex and much research is still needed. Existing insights suggest that conflicts may worsen gender inequalities that existed before the outbreak of violence. The unequal distribution of land property rights in many parts of the world serves as an example. Moreover, women (and children) are among those most affected by both violent conflict and natural disasters. At the same time, women carry much of the burden of trying to implement rehabilitation measures after crisis events.

Land & Food

Increasing water scarcity, desertification and crop failures due to extreme weather events are becoming more and more of a threat to global food production. While the world’s population continues to grow rapidly, food production is unable to keep pace. Due to the global food crisis in 2008, the number of hungry people reached the symbolic one billion threshold for the first time – corresponding to about 16 percent of world population. Food insecurity may be a consequence or cause of conflicts. Violent conflicts often lead to the destruction of agricultural infrastructure and means of production, as well as to the displacement of local communities.

Read more

Minerals & Mining

In the past, the discovery and tapping of valuable or strategic resources like valuable minerals, oil and natural gas, particularly in developing and emerging countries, has often led to large scale environmental contamination and negative development. The "resource curse" of some countries shows that the wealth from resource yields is frequently unfairly distributed; instead of serving development it advanced the formation of corrupt elites and in some cases even led to conflicts and civil wars. Measures in various sectors and at all levels are important in order to use the potential of these natural resources in a manner that is sustainable and prevents conflicts.

Read more

Private Sector

The spread of violent conflict not only affects people but also companies located in such regions. Destruction of investments and infrastructure, collapse of markets and trade partnerships, flight and expulsion of employees are phenomena of conflicts and environment-induced crises that directly affect companies in unstable regions. Almost all branches of the economy thus have a clear interest in a stable and peaceful environment for their activities. Conversely, the business sector plays an important role in the interaction of economic growth, social development and a healthy environment, all of which can advance peace and sustainable development.

Environmental issues have a significant security dimension. Access to, and overuse of, natural resources often play a key role in civil wars or other forms of internal domestic conflict. This is compounded by climate change and environmental degradation. Climate change is now widely recognised as a non-traditional, risk-multiplying threat that will have increasing security impacts. Key risks with possible implications for human and national security include water scarcity, food crises, natural disasters, and displacement. More preventive diplomacy and advocacy is needed to address the strategic implications of climate and environmental change.

Sustainable Transformation

Sustainable Transformation allows societies to profit from a growing, environmentally sustainable and socially inclusive economy – especially in emerging and developing countries. This requires a higher up-front investment, but the benefits of a sustainable transformation in the medium and long term are significant. For instance, energy cost savings and reducing the impact of price volatility offer major incentives for deploying renewable energies and promoting energy efficiency. Such benefits exist in all key sectors of the economy.

Technology & Innovation

Innovations and technologies are already readily available and affordable but their global diffusion and uptake remains a challenge. Innovation and technology are crucial to achieving ambitious climate change mitigation and adaptation targets. However, research and development often do not receive appropriate public support. Developing countries can leapfrog high-carbon industrialisation phases by adopting, deploying and improving existing innovations and technologies. For this, it is essential to minimise financial, administrative and political barriers.


The availability of freshwater resources in sufficient quantity and quality is essential for the preservation of human health and sound ecosystems. The use of water resources is also vital, however, for economic development: whether for agriculture, industrial production or for electricity generation. The world's freshwater resources are distributed very unevenly in terms of geography and seasons. In addition, water shortage is becoming more prevalent in several regions due to population growth, economic development, urbanisation and increasing environmental pollution. Thus, water resources can hold potential for conflicts between parties who have different interests and needs.

The environment in Asia is already under tremendous pressure as a result of the unsustainable use of land, forests, water and even air in many regions. Climate change will only exacerbate these challenges. Rising sea levels will likely endanger densely populated areas, changes in the monsoon patterns can strongly impact agriculture, melting glaciers will increase long-term water scarcity, and extreme weather events such as heavy rainfall and cyclones can pose further hazards.

Central America & Caribbean

Natural disasters and water scarcity are key challenges for most of Central America and the Caribbean. These challenges will become even more pronounced as the climate changes. Weak resource and disaster risk management and land disputes pose additional security challenges for large parts of the region. Several countries of Central America and the Caribbean have limited adaptive capacities as they face political instability caused by high social inequality, crime, corruption, and intra-state conflicts.

As one of the most developed and most densely populated regions in the world, Europe makes heavy use of its resources, resulting in difficult trade-offs and negative consequences for the environment and ecosystems. Land is used for settlements, agriculture and dense infrastructure, creating problems of soil degradation. Water resources are stressed due to unsustainable agricultural practices. Despite nature protection policies, Europe continues to lose biodiversity at an alarming pace. Some of these trends are exacerbated by climate change, which is expected, for instance, to lead to shifts in water availability.

Global Issues

Resource scarcities, environmental pollution and climate change are not limited by national borders, but often have a transboundary or even global impact. These issues interact with political stability, governance structures and economic performance, and can trigger or worsen disputes and violent conflicts. Exacerbating some of these trends, climate change is likely to lead to the degradation of freshwater resources, declines in food production, increases in storm and flood disasters and environmentally induced migration. All these developments pose potential for conflict.

Middle East & North Africa

The geopolitical position of the Middle East and North Africa (MENA), its fossil fuel resources, high population growth and the political changes spurred by the Arab Spring all make the region one of the most dynamic in the world. Nevertheless, it is also one of the most arid and environmentally stressed. Dwindling water resources, limited arable and grazing land, high pollution from household and industrial waste, remnants of conflicts and increasing desertification are key environmental challenges.

North America

Climate change has various impacts on the three North American countries of Canada, Mexico and the US. Canada and the US have well-developed adaptive capacities and foster the strengthening of capacities in other regions as well. With high per capita emissions, these two countries also bear a greater responsibility for a changing climate. Mexico has a sound national strategy for climate change adaptation, yet fewer capacities than Canada and the US. The poorer and rural populations of Mexico are especially vulnerable to climate change, due to an increased sensitivity and a lower adaptive capacity.

Oceania & Pacific

In Oceania, population growth and economic development trends put a strain on oceanic and island ecosystems. Freshwater scarcity, overexploitation of fisheries, loss of land biodiversity, forests and trees, invasive species, soil degradation, increasing levels of settlement, poor management of solid and hazardous waste and disproportionate use of coastal areas are some of the problems. Climate change exacerbates most of these trends, while also raising questions about the future sovereignty of some island states.

South America

South America has diverse and unique ecosystems and is very rich in biodiversity. Weak natural resource management, land disputes and extreme weather events bring about significant challenges for the region. While South America accounts for relatively few CO2 emissions, the changing climate will alter its ecosystems and greater climate variability will lead to more hurricanes, landslides, and droughts.

Sub-Saharan Africa

In many African states, environmental security issues rank high on the political agenda. Throughout the continent, countries suffer from water scarcity, food insecurity and energy poverty. These chronic and worsening resource scarcities have severe livelihood implications and are exacerbated by political conflicts over access to and control over these resources. Climate change may seriously threaten political and economic stability in Africa. It may also put a severe strain on the capacities of states and societies to co-ordinate activities, to communicate and to organize.
