Executive Summary
The African Great Lakes region represents a critical nexus of immense natural wealth, diverse livelihoods, and complex geopolitical dynamics. Comprising seven major lakes integral to the East African Rift System, this region spans ten countries and supports millions of people through its rich freshwater ecosystems. The lakes are unparalleled biodiversity hotspots, particularly for endemic fish species, contributing significantly to regional economies through fisheries, agriculture, tourism, and resource extraction. However, this vital system faces profound and interconnected challenges. Severe environmental degradation, driven by pollution, overfishing, invasive species, and land degradation, directly undermines economic stability and food security. These ecological and economic pressures, in turn, exacerbate social tensions and fuel geopolitical conflicts, particularly those rooted in competition over scarce resources, land, and the impacts of human migration. Persistent political instability and insecurity further impede conservation efforts and sustainable development. Addressing these multifaceted challenges necessitates integrated, transboundary governance frameworks and comprehensive strategies that recognize the systemic interdependencies between ecological health, economic prosperity, and regional peace. Without such holistic approaches, the region’s potential for sustainable development and stability remains significantly constrained.
1. Introduction: The African Great Lakes Region – A Nexus of Nature, Livelihoods, and Conflict
The African Great Lakes region is a geographical and ecological marvel, forming a central component of the East African Rift System. This area is not merely a collection of large freshwater bodies but a dynamic and interconnected system that profoundly influences the environmental, social, and political landscapes of East, Central, and Southern Africa. The study of this region requires an integrated approach, acknowledging the intricate and often challenging interdependencies between its ecological health, economic vitality, and geopolitical stability.
Defining the African Great Lakes and their regional significance
The African Great Lakes consist of seven principal lakes: Victoria, Tanganyika, Malawi, Turkana, Albert, Kivu, and Edward. These vast water bodies are situated within and around the East African Rift, a series of massive fissures in Earth’s crust. Collectively, these lakes extend across ten countries: the Democratic Republic of Congo (DRC), Burundi, Ethiopia, Kenya, Malawi, Mozambique, Rwanda, Tanzania, Uganda, and Zambia. Their combined surface area is approximately 138,447 square kilometers.
The sheer scale of these lakes underscores their global importance. Lake Victoria, for instance, is recognized as the world’s second-largest freshwater lake by surface area, covering approximately 69,000 square kilometers. Lake Tanganyika, while smaller in surface area, holds an immense volume of water, estimated at nearly 19,000 cubic kilometers, making it the second-largest lake in the world by volume and containing more freshwater than the five North American Great Lakes combined. Lake Malawi is the third-deepest freshwater lake globally. This impressive hydrographic system is fundamental to the climate, economy, and social development of Eastern Africa.
Interconnectedness of ecological, economic, and geopolitical dimensions
The African Great Lakes region is characterized by a complex and dynamic interplay where environmental degradation, such as pollution and overfishing, directly undermines economic stability through declining fish stocks and food insecurity. These economic pressures, in turn, often exacerbate social tensions and geopolitical conflicts, particularly those driven by competition over scarce resources and human migration. Conversely, persistent political instability and insecurity can severely impede conservation efforts and hinder sustainable economic development initiatives.
A critical observation in this region is the profound systemic vulnerability and opportunity presented by the interconnectedness of its ecological, economic, and geopolitical elements. For example, the ecological collapse of Lake Victoria, triggered by invasive species and overfishing , directly impacts the livelihoods of millions of people who depend on its resources. This economic hardship can then contribute to social instability and increased migration pressures. Similarly, the illicit trade of strategic minerals in the Democratic Republic of Congo fuels armed groups , leading to severe humanitarian crises and significantly hindering environmental protection efforts in mining areas. This demonstrates that these elements are not merely co-occurring problems but are causally linked, forming a complex system. This system represents both a systemic vulnerability, where a shock to one component can destabilize the entire system, and an opportunity, where integrated, holistic interventions can yield synergistic benefits across all dimensions. Policy interventions, therefore, must be designed with a deep understanding of these inherent interdependencies to avoid unintended negative consequences and to leverage positive synergies. For instance, promoting sustainable fisheries, an ecological and economic intervention, can reduce poverty and food insecurity, which in turn alleviates pressure on natural resources and diminishes potential drivers of conflict, thereby contributing to geopolitical stability. Conversely, neglecting one aspect, such as environmental protection, will ultimately undermine economic development and peacebuilding efforts.
2. Ecological Landscape: Biodiversity, Vulnerability, and Environmental Degradation
The African Great Lakes are not only geographically significant but also possess unique ecological characteristics, supporting an extraordinary array of life. However, these vital ecosystems are under severe threat from a combination of human-induced pressures and the overarching impacts of global climate change.
2.1. Geographic and Hydrological Characteristics
The African Great Lakes are primarily situated within the East African Rift System, a vast geological formation that has shaped their unique geomorphology, including their remarkable depths. Lake Tanganyika is one of the deepest lakes globally, reaching depths of up to 1,471 meters, while Lake Malawi is the third deepest freshwater lake in the world, with depths up to 706 meters.
The hydrological connections of these lakes vary significantly, influencing broader regional and continental water systems. Lake Victoria drains into the White Nile River, Lake Tanganyika into the Congo River, and Lake Malawi into the Zambezi River. This highlights their integral role in the larger hydrological networks of Africa. Lake Turkana is distinct as the world’s largest permanent desert and alkaline lake, with its water balance predominantly controlled by evaporation and over 90% of its inflow originating from the Omo River in Ethiopia. Lake Albert’s water is notably saline due to high rates of sedimentation and evaporation, despite being a freshwater lake.
The diverse hydrological characteristics and outflow patterns of these lakes reveal that they are not isolated entities but integral parts of larger river basins and continental water systems. For example, Lake Victoria feeding the Nile River and Lake Tanganyika feeding the Congo River demonstrate their interconnectedness. The extreme reliance of Lake Turkana on the Omo River, for instance, means that major upstream developments like the Gibe III hydropower dam and large irrigation schemes in Ethiopia have direct, potentially devastating, downstream impacts on the lake’s water levels, ecology, and the livelihoods of communities in Kenya. This creates complex upstream-downstream dependencies and vulnerabilities that inherently transcend national borders, demanding sophisticated international cooperation and dispute resolution mechanisms. Management strategies for individual lakes must therefore extend beyond their immediate boundaries to consider the broader basin-wide hydrological connections and potential cascade effects. This emphasizes the critical need for integrated water resource management (IWRM) frameworks that account for the entire hydrological system, from headwaters to lake outflows, and involve all riparian states in collaborative planning and decision-making to ensure equitable and sustainable water use.

| Edward | DRC, Uganda | 2,325 | N/A | N/A | Semliki River (to Lake Albert) | Shared by Uganda and DRC |
2.2. Rich Biodiversity and Unique Ecosystems
The African Great Lakes are globally recognized as unparalleled biodiversity hotspots, particularly for their exceptional fish diversity. These lakes are often referred to as “evolutionary laboratories” due to the remarkable speciation events that have occurred within them.
Lake Malawi stands out as an extraordinary example, hosting an astonishing 800 to 1000 fish species, almost exclusively from the Cichlidae family. This makes it the most fish species-rich lake in the world. Lake Tanganyika is similarly remarkable, harboring at least 1500 species, with approximately 600 species being endemic to the lake. This includes 245 morphologically diverse and colorful cichlid fish species, as well as unique endemic ostracods, gastropods, shrimp, and crabs. Lake Victoria, despite its current challenges, was once home to an astonishing diversity of over 350 endemic cichlid species. Lake Turkana supports over 40 species of fish, including several endemic ones, and is home to the world’s largest remaining population of Nile crocodiles. Lake Kivu, while having a relatively lower abundance of fish species, is astonishingly unique, with half of its 29 fish species found nowhere else on Earth. Lake Albert, though having lower overall fish diversity (40-55 species) compared to other African Great Lakes, boasts significant endemism, with 36% of its cichlid population and 5% of non-cichlid fish species found only in the lake.
Beyond fish, the lakes and their surrounding basins support diverse flora and fauna. This includes local and migratory bird species such as flamingos and pelicans, crocodiles, hippopotamuses, elephants, buffaloes, and various unique plant communities like papyrus swamps.
The pervasive presence of high endemism across the African Great Lakes signifies their unparalleled global biological value, particularly for evolutionary studies. However, this unique characteristic simultaneously renders these ecosystems and their species exceptionally vulnerable. When a species is endemic to a single lake, any localized threat, such as a specific invasive species, a particular pollutant, or localized overfishing, can lead to its global extinction. This has been tragically exemplified by the massive loss of cichlid species in Lake Victoria following the introduction of the Nile perch. These species, having evolved in relative isolation, often lack the genetic diversity or adaptive capacity to cope with rapid, human-induced environmental changes. Consequently, conservation efforts in the African Great Lakes must adopt a highly targeted and urgent approach, prioritizing the protection of these irreplaceable endemic species and their fragile habitats. This necessitates context-specific interventions, such as establishing protected breeding grounds and controlling invasive species, alongside broader regional strategies to mitigate systemic threats. The irreversible nature of endemic species loss underscores the profound global responsibility in safeguarding these unique evolutionary laboratories.
Table 2.2: Endemic Species and Biodiversity Hotspots by Lake
| Lake Name | Total Fish Species (approx.) | Endemic Fish Species (approx.) | Other Notable Endemic/Unique Biodiversity | Key Ecological Feature/Note |
| Victoria | 350+ (historically) | 350+ (cichlids, historically) | N/A (significant cichlid loss) | Formerly a cichlid evolutionary hotspot, now severely impacted by Nile perch |
| Tanganyika | 1500+ | 600 (including 245 cichlids) | Endemic ostracods, gastropods, shrimp, crabs | Global biodiversity hotspot, microcosm for evolutionary studies |

| Kivu | 29 | Half of 29 species | 142 plant species, 80 bird species, 52 invertebrates | Unique fish composition, harbors endangered species |
| Edward | N/A | N/A | N/A | Shared by Uganda and DRC |
2.3. Major Environmental Threats and Their Impacts
The African Great Lakes are widely recognized as among the world’s most endangered water systems. They face a complex array of interconnected threats, including overuse of resources, introduction of invasive species, extensive habitat degradation, widespread deforestation, pervasive pollution, and the overarching impacts of climate change.
2.3.1. Pollution and Water Quality Decline
Pollution from diverse sources constitutes a major and pervasive problem across the Great Lakes. Untreated wastewater from urban centers, industrial effluents (which can contain harmful substances such as arsenic, cadmium, chromium, copper, and lead), agricultural runoff laden with fertilizers and pesticides, and domestic sewage are routinely discharged into the lakes.
This influx of pollutants leads to severe eutrophication, characterized by the over-enrichment of nutrients, resulting in massive algae blooms and subsequent oxygen depletion (anoxia or “dead zones”) in the water column. This process severely impacts aquatic life, making large areas of lakes like Victoria uninhabitable for fish. A critical observation is that while more visible threats like overfishing or invasive species receive significant attention, eutrophication and subsequent oxygen depletion represent a critical, pervasive, and often less immediately apparent threat. This points to a systemic failure in land-use management and sanitation infrastructure rather than isolated incidents. The “dead zones” are not a direct input but a consequence of diffuse pollution from vast catchment areas, including agriculture and urban centers lacking proper waste treatment. The decomposition of algae, fueled by these nutrients, consumes oxygen, creating conditions where fish cannot survive, leading to habitat loss and fish kills. This indicates a fundamental breakdown in the natural nutrient recycling processes within the lake ecosystems. Effectively addressing water quality degradation therefore requires a comprehensive, multi-sectoral approach that extends far beyond the lakes themselves. It necessitates significant investment in improved sanitation infrastructure in riparian communities, stringent controls on industrial discharges, and the widespread adoption of sustainable land management practices, such as reduced fertilizer use and erosion control, across entire catchment areas. Without tackling these upstream and diffuse sources, efforts to manage fisheries or combat invasive species will be continuously undermined by a deteriorating aquatic environment.
2.3.2. Overfishing and Fisheries Collapse
Overfishing is a persistent and severe threat across nearly all the African Great Lakes, leading to drastic reductions in fish stocks and significant species loss. Lake Victoria’s once-thriving native cichlid fishery collapsed dramatically during the first half of the 20th century, primarily due to intense overfishing, exacerbated by the later introduction of the Nile perch. Lake Malawi has experienced significant declines in commercial fish catches, with key species like chambo and kampango declining by up to 90-94% between 2006 and 2016, and some endemic cichlids now critically endangered. Lake Tanganyika also faces intense fishing pressure, particularly in its northern (Burundi) and southern (Zambia) parts, leading to a significant decline in high-valued species like Sleek Lates. The problem is compounded by unsustainable fishing practices, widespread illegal, unreported, and unregulated (IUU) fishing, and the pervasive use of destructive gear, including gill nets, drag nets, and monofilament nets.
The consistent depiction of a direct causal link between high population growth rates , widespread poverty , and the intensification of overfishing reveals a vicious cycle. As populations grow, the demand for fish, a primary protein source, increases. In contexts of limited alternative livelihoods and high poverty, communities become disproportionately dependent on fishing for survival. This economic desperation drives fishers to resort to more efficient but destructive methods, target immature fish, or fish in breeding grounds, further depleting already stressed stocks. This creates a negative feedback loop: environmental degradation, manifested as declining fish stocks, worsens economic conditions, which in turn intensifies unsustainable practices, trapping communities in a cycle of diminishing returns and increasing vulnerability. Sustainable fisheries management in the African Great Lakes is not merely an ecological concern but an urgent economic and social imperative. Achieving sustainability requires a fundamental shift from open-access exploitation to regulated, community-managed systems, coupled with robust enforcement and the development of viable alternative livelihoods. Promoting aquaculture, improving post-harvest handling, and diversifying income sources are crucial to reduce direct pressure on wild fish stocks and build economic resilience among riparian communities.
2.3.3. Invasive Species Proliferation
The deliberate or accidental introduction of non-native species has had devastating consequences for the native ecosystems and biodiversity of the African Great Lakes. The most infamous example is the Nile perch (Lates niloticus), introduced to Lake Victoria in 1954. This large, voracious predator led to the decimation and near extinction of over 350 endemic cichlid species, drastically altering the lake’s biomass composition and triggering an ecosystem collapse.
Aquatic invasive plants, such as the water hyacinth (Eichhornia crassipes), pose significant threats in lakes like Victoria and Albert, disrupting navigation, fishing, and altering aquatic habitats by depleting oxygen. Terrestrial invasive species, like the thorny shrub Prosopis, are rapidly encroaching upon river deltas and shorelines, as seen in Lake Turkana, impacting local ecology and fisheries by creating impenetrable thickets and making areas inaccessible. The case of the Nile perch in Lake Victoria serves as a powerful, albeit tragic, illustration of how a seemingly beneficial introduction, intended to boost fish catches and create a commercial fishery, can trigger a catastrophic and irreversible ecological domino effect. The disappearance of algae-eating cichlids, for example, allowed algae to flourish unchecked, further depleting oxygen levels in the lake. Moreover, the need to preserve the much larger Nile perch led to increased deforestation for smoking fish, which in turn exacerbated harmful runoff into the lake. This chain reaction demonstrates that ecosystems are complex, interconnected systems where interventions, even well-intentioned ones, can have profound and unpredictable negative consequences that extend far beyond the initial target. This highlights the critical importance of stringent biosecurity measures and rigorous, long-term ecological impact assessments before any deliberate introduction of non-native species. For existing invasive species, integrated management strategies are essential, combining biological, chemical, and mechanical control methods, alongside robust community engagement and monitoring. The long-term costs of managing invasive species and their ecological damage far outweigh the perceived short-term benefits of their introduction.
2.3.4. Habitat Loss, Deforestation, and Land Degradation
Driven by high population growth and the associated demand for land, extensive land clearing for agriculture, logging for timber and fuel wood, and human settlement are leading to widespread deforestation, severe soil erosion, and degradation of critical wetlands across the lake basins. This terrestrial degradation directly increases sedimentation and nutrient loads flowing into the lakes, further exacerbating water pollution and leading to the loss of vital habitats for aquatic species. Wetlands, which play a crucial role in filtering pollutants and providing essential fish breeding grounds, are particularly vulnerable and are being extensively drained or degraded.
The consistent revelation of a direct and strong causal link between human activities on land within the lake catchment areas and the ecological health of the lakes themselves is a significant finding. Deforestation and unsustainable agricultural practices, such as cultivation on steep slopes and a lack of soil conservation, lead to increased soil erosion and runoff. This eroded soil and associated nutrients from fertilizers and waste are then carried into the lakes, causing siltation and eutrophication, which in turn degrade aquatic habitats and water quality. This highlights that “lake management” is not confined to the water body but must encompass the entire terrestrial basin that drains into it. Effective conservation and sustainable management of the African Great Lakes therefore necessitate an integrated land-use planning approach. This includes large-scale reforestation and agroforestry initiatives, promotion of sustainable agricultural practices, such as terracing, contour plowing, and the use of organic manure, and robust protection and restoration of critical wetland ecosystems. These upstream interventions are fundamental to reducing sediment and nutrient loads, improving water quality, and ultimately safeguarding the aquatic biodiversity and ecosystem services of the lakes.
2.3.5. Climate Change: Amplifying Ecological Stress
Climate change is identified as the major environmental challenge of the 21st century for the African Great Lakes region, significantly aggravating existing problems related to resource exploitation, habitat degradation, land use, invasive species, and pollution. Rising temperatures in the AGL region are already affecting lake processes and fish yields. For deep, stratified lakes like Tanganyika, warming can reduce nutrient recycling in upper layers, leading to a decline in primary production and subsequently impacting pelagic fish catches. Altered rainfall patterns are causing an increased frequency and severity of both droughts and floods, which directly impact water levels, disrupt aquatic ecosystems, and threaten regional food security. Lake Turkana’s water balance and fisheries, for example, are highly sensitive to rainfall and drought, a vulnerability expected to worsen with climate change intensification.
The consistent portrayal of climate change not as an isolated environmental problem but as a “risk multiplier” that intensifies and compounds existing vulnerabilities and challenges across the Great Lakes region is a critical observation. It exacerbates the impacts of resource exploitation, accelerates habitat degradation, facilitates the spread of invasive species, and worsens pollution. This means that even if local stressors are managed effectively, the overarching effects of climate change can undermine these efforts, rendering the region’s ecosystems and the livelihoods dependent on them increasingly precarious and fragile. The changing hydrological cycles, for instance, directly impact water availability and quality, which then affects fisheries, agriculture, and human health. Adaptation and mitigation strategies must therefore be comprehensively integrated into all development and conservation plans for the African Great Lakes. This includes developing and implementing climate-resilient agricultural practices, establishing robust early warning systems for floods and droughts, and promoting livelihood diversification to reduce communities’ over-reliance on climate-sensitive sectors. Furthermore, regional and international cooperation on climate action is paramount, as the impacts transcend national borders and require collective responses.
3. Economic Dynamics: Resource Dependence, Development, and Poverty
The African Great Lakes region is characterized by economies deeply intertwined with its natural resources. While these resources offer substantial development potential, the region also grapples with significant poverty and challenges in translating natural wealth into widespread, sustainable prosperity.
3.1. Key Economic Sectors and Their Contribution
3.1.1. Fisheries: A Primary Protein and Livelihood Source
Fisheries represent a foundational pillar of the regional economy, providing essential protein and sustaining the livelihoods of millions of people across the Great Lakes basin. Lake Victoria is home to the world’s largest freshwater fishery, producing approximately 1 million tons of fish annually. This sector directly employs about 200,000 people and supports the livelihoods of up to 4 million individuals. It also generates over $150 million in export earnings and provides high-quality fish protein to approximately 8 million people in its basin.
Lake Tanganyika’s fisheries yield between 165,000 to 200,000 tons of fish per year, employing around 100,000 people in related activities and supplying 25-40% of the protein needs for about 1 million people. The lake is also internationally recognized as a source of prized ornamental fish for the aquarium trade. Lake Malawi’s fishery supports the livelihoods of over 1.6 million people, with 56,000 fishers harvesting more than 100,000 tons of fish per year. Fish from Lake Malawi constitute about 70% of the animal protein consumed in Malawi. Lake Albert ranks second among the African Great Lakes in terms of fishery yield, with an estimated catch of 172,000 tons per year, directly supporting approximately 15,420 fishers in Uganda and 20,000 in the Democratic Republic of Congo (DRC). Lake Turkana’s fishery is predominantly for subsistence purposes, employing about 3,000 fishers and yielding approximately 4,000 tons of fish per year, supporting the livelihoods of about 300,000 Kenyans from six main tribal groups. The fish resources in Lake Turkana are considered underutilized, presenting potential opportunities for commercial fisheries investment.
The data unequivocally demonstrates the immense productivity of the African Great Lakes fisheries and their critical role in sustaining millions of livelihoods, providing essential protein, and generating significant export earnings. However, this very abundance and high dependence create a profound vulnerability. The economic imperative to extract fish, especially in contexts of high population growth and poverty, leads to intense pressure and often unsustainable practices, such as overfishing and the use of destructive gear. This is a classic example of a “tragedy of the commons” scenario, where individual short-term gains (more fish caught immediately) lead to collective long-term losses (depleted fish stocks, ecosystem collapse). The economic value paradoxically drives the degradation of the resource it depends on. Sustainable fisheries management in the African Great Lakes is not merely an ecological concern but an urgent economic and social imperative. Achieving sustainability requires a fundamental shift from open-access exploitation to regulated, community-managed systems, coupled with robust enforcement and the development of viable alternative livelihoods. Promoting aquaculture, improving post-harvest handling, and diversifying income sources are crucial to reduce direct pressure on wild fish stocks and build economic resilience among riparian communities.
3.1.2. Agriculture and Land Use
The region’s fertile soils and favorable climate provide a powerful incentive for human settlement and extensive agricultural activity. In the Lake Victoria basin, agriculture is diverse, supporting the cultivation of cash crops such as tea and coffee, alongside essential food crops like beans, maize, and bananas. Agriculture, livestock raising, and the processing of these products constitute the main industries within the drainage basin of Lake Tanganyika. Malawi’s national economy is predominantly agricultural, with the sector accounting for over 80% of the country’s GDP. Key export crops include tobacco, tea, sugar, coffee, and macadamia. Subsistence agriculture, cattle herding, and logging are prevalent economic activities around Lake Albert, supporting local populations.
The evidence clearly establishes agriculture as a vital economic sector across the African Great Lakes region, providing food security and livelihoods for millions, and significantly contributing to national GDPs, as seen in Malawi where it accounts for over 80% of GDP. However, simultaneously, the research consistently links agricultural expansion and prevailing practices, such as land clearing for cultivation, the use of fertilizers and pesticides, and overgrazing by livestock, to major environmental threats to the lakes, including deforestation, soil erosion, and nutrient pollution. This highlights a fundamental and critical tension: the very activity essential for immediate human survival and economic growth is also a primary driver of long-term ecological degradation, creating a self-defeating cycle. Achieving sustainable development in the region therefore requires a transformative shift towards sustainable agricultural practices. This includes promoting agroforestry, terracing on slopes, organic farming methods to reduce chemical inputs, and responsible land-use planning to prevent further deforestation and soil erosion. Investing in agricultural innovation and extension services that support these practices is crucial to ensure both food security and the ecological health of the lakes.
3.1.3. Tourism Potential and Development
Several of the African Great Lakes and their surrounding areas offer significant, yet often underdeveloped, tourism potential. This includes opportunities for sport fishing, boating, cruising safaris, and wildlife viewing within numerous national parks and protected areas. Murchison Falls National Park in Uganda, bordering Lake Albert, is highlighted as one of the nation’s leading tourist attractions, home to diverse wildlife including buffaloes, lions, leopards, and elephants. Lake Tanganyika offers tourism opportunities in four national parks (Gombe Stream, Katavi, and Mahale Mountains National Parks in Tanzania; Nsumbu National Park in Zambia) and hosts an annual international fishing competition at Kasaba Bay. Burundi’s capital, Bujumbura, located at the northeastern end of Lake Tanganyika, also hosts many tourist hotels. Lake Turkana boasts three national parks (Sibiloi, Central, and South Islands) which provide significant tourism opportunities. The lake itself is a major recreation area for swimming, sport fishing, and other marine sports.
The research clearly indicates the substantial natural beauty and biodiversity of the Great Lakes region, which should logically translate into significant tourism revenue. However, the geopolitical section of this report highlights persistent insecurity, armed conflicts, and cross-border tensions, particularly in the Democratic Republic of Congo and its border regions. This creates a direct contradiction: the very assets that could drive economic diversification and provide alternative livelihoods, such as tourism, are located in areas often deemed unsafe or unstable, thereby limiting foreign investment and visitor numbers. The economic benefits of tourism remain largely unrealized due to the prevailing geopolitical climate. Realizing the full economic potential of tourism in the African Great Lakes region is contingent upon significant and sustained improvements in regional security and stability. Peacebuilding initiatives, coupled with targeted investments in tourism infrastructure and marketing, must go hand-in-hand. Developing community-based tourism models can also provide alternative livelihoods for local populations, reducing their reliance on environmentally damaging activities and fostering a greater stake in peace and conservation.
3.1.4. Resource Extraction: Minerals, Oil, and Methane
The Great Lakes territory, particularly in the Democratic Republic of Congo, is strategically crucial due to its vast reserves of important mineral resources, including coltan, cobalt, tin, and tungsten, which are essential for electronic devices and global technology supply chains. However, the control and often illicit trade of these minerals are central drivers of ongoing conflicts, fueling armed groups and creating a black market estimated in billions of dollars.
Significant quantities of petroleum have been discovered in the Lake Albertine rift basin, shared by Uganda and the DRC. Test drilling has already commenced in environmentally sensitive protected areas such as Murchison Falls National Park in Uganda. This planned oil extraction poses substantial environmental risks, including the challenge of managing toxic wastewater and mud, and causes significant disturbance to wildlife habitats. It also exacerbates existing land conflicts due to increased population density and land speculation. Lake Turkana also has potential oil resources along its western shores.
Lake Kivu, shared by Rwanda and the DRC, contains vast amounts of dissolved methane gas (estimated at 60 billion m³) and carbon dioxide, presenting a unique opportunity for power generation. Rwanda is already successfully extracting methane from the lake to generate electricity for its national grid (currently 76 MW), with a potential for a sustainable supply of 100 MW for up to 100 years. However, improper extraction methods could destabilize the lake’s stratification, potentially triggering catastrophic gas eruptions.
The presence of highly valuable natural resources—minerals, oil, and methane—presents immense economic opportunities for the African Great Lakes region, offering potential for energy security, revenue generation, and economic growth. However, the available information consistently highlights a critical paradox: these very resources frequently become a primary source of instability, environmental degradation, and conflict. The lack of transparent governance, weak regulatory frameworks, illicit trade, and the involvement of armed groups and external actors seeking control over these resources transform potential prosperity into a “resource curse.” This is a complex causal relationship where economic potential is undermined by geopolitical realities and poor governance. To transform resource wealth into sustainable development rather than a driver of conflict and environmental harm, robust governance frameworks are essential. This includes ensuring transparency in resource contracts, implementing equitable benefit-sharing mechanisms for local communities, and enforcing stringent environmental regulations for extraction activities. International cooperation is also crucial to curb illicit trade, promote responsible sourcing of minerals, and hold accountable actors who fuel conflict through resource exploitation. Without these measures, the region’s natural capital will continue to be a source of instability rather than prosperity.

4. Geopolitical Landscape: Conflicts, Resource Sharing, and Regional Stability
The African Great Lakes region is a geopolitical flashpoint, characterized by a complex history of conflict, persistent instability, and intense competition over natural resources. The security and stability of this region are crucial for the entire African continent.
4.1. Historical Context of Conflicts
The region has experienced recurring cycles of violence and instability since the 1960s, with particularly intense and protracted conflicts in Burundi, Rwanda, Uganda, and the Democratic Republic of Congo (DRC). These conflicts are often rooted in identity manipulation, historical grievances, exclusion from governance, and competition over natural resources. The arbitrary drawing of colonial boundaries by European powers, disregarding local situations, set the stage for ethnic conflicts and border disputes after nations gained independence. The unresolved legacies of the 1994 Genocide against the Tutsi in Rwanda, inter-ethnic tensions in Burundi, and weak governance in parts of the DRC continue to affect peacebuilding efforts. The number of conflicts and battle-related deaths increased dramatically in the 1980s and 1990s, remaining very high in the 2000s.
4.2. Current Geopolitical Landscape and Conflicts
The security situation in eastern DRC has significantly deteriorated, with the M23 rebel group more than doubling its control of territory in North and South Kivu provinces, capturing strategic cities like Goma. This offensive, which escalated dramatically in January 2025, has triggered a massive exodus, displacing over 400,000 people and resulting in significant casualties. The crisis has taken on an increasingly complex geopolitical dimension due to Rwanda’s alleged military and logistical support for the M23, leading to a total rupture of diplomatic relations between Kinshasa and Kigali. Military mobilization on both sides of the border and border closures have further heightened tensions. International pressure, including sanctions from the US, UK, Canada, and Germany, has been applied to M23 leaders and Rwanda, though Kigali has criticized these measures as unhelpful.
4.3. Resource-Driven Conflicts
Control over strategic mineral mines is a central economic driver of conflict in the region. The illicit trade of natural resources, estimated in billions, fuels armed groups and impacts regional economies. The extraction of “3T minerals” (coltan, tin, and tungsten), crucial for electronic manufacturing, lies at the heart of the conflict between the Congolese government, M23, and Rwanda. Since 2021, M23 has seized control of key mining sites, regulating extraction and export, primarily to Rwanda, which has become a major global exporter despite lacking significant domestic reserves.
Conflicts over natural resources arise when parties disagree about their management and distribution, and about the protection of the resources and related ecosystems. These conflicts can escalate into destructive relations and violence when the parties are unable or unwilling to engage in constructive dialogue. This problem is exacerbated when social mechanisms and institutions for managing and resolving conflict break down. The resource-driven conflict is not localized; it is linked to an endless scramble for power, which is again linked to resources, between internal and external actors. For example, competition between neighboring states over the extraction of mineral wealth has fueled conflict in eastern DRC since 1998, leading to broader instability in the Great Lakes region.
Beyond minerals, competition for water and pastures also drives communal conflicts, such as those between pastoralist groups across the Kenyan-Ugandan border and in the Omo-Turkana basin between Kenyan and Ethiopian pastoralists and fishermen. The construction of large hydropower dams, like the Gilgel Gibe III on Ethiopia’s Omo River, raises concerns about water abstraction for commercial agriculture and its potential to incite popular protests and exacerbate existing conflicts among downstream communities. The African Great Lakes are international waters, shared by multiple countries, and the exploitation of these transboundary resources is often associated with conflicts due to differing national interests. Incidents of fishermen being arrested for crossing borders or armed militias using lakes as getaway avenues highlight these tensions.
4.4. Humanitarian Impacts
The ongoing conflicts and environmental degradation have severe humanitarian consequences. The region faces a staggering 7.1 million internally displaced persons and 2.7 million refugees in neighboring countries. Over 27 million people are in severe food insecurity, and health and education systems have collapsed in many areas. Young people, who constitute the majority of the population, are particularly vulnerable, exposed to direct violence, forced recruitment into armed groups, sexual and gender-based violence, and a lack of schooling and job opportunities. Climate change acts as a “risk multiplier,” amplifying the risk of conflict and forcing already vulnerable people to flee their homes, with many displaced populations living in climate “hotspots” where they lack resources to adapt.
4.5. External Actors and Interests
The conflict in the DRC and the broader Great Lakes region has drawn the attention of major global powers. China, with its expanding economic footprint in Africa, views the DRC as a crucial source of raw materials, particularly cobalt, a critical mineral for technological development. China controls approximately 80% of Congolese cobalt production through substantial investments. The United States has also shown interest in diversifying its critical mineral supply and has been involved in mediation efforts, culminating in a recent peace deal between DRC and Rwanda, accompanied by commitments for a “regional economic integration framework” and promises of US investment in eastern DRC’s critical mineral reserves. The international community, including the African Union and the UN, is urged to significantly increase its engagement and support for peace initiatives, as the cost of inaction or inadequate response could be devastating for Central and Eastern Africa.
5. Governance and Cooperation: Challenges and Progress
Effective governance and robust regional cooperation are paramount for addressing the complex ecological, economic, and geopolitical challenges facing the African Great Lakes. While significant hurdles remain, various organizations and initiatives are working towards sustainable management and peacebuilding.
5.1. Regional Organizations and Initiatives
Several regional bodies and initiatives have been established to promote cooperation and sustainable management of the Great Lakes and their shared resources.
- Lake Victoria Basin Commission (LVBC): Established under the East African Community (EAC), the LVBC is responsible for coordinating the sustainable development and management of the Lake Victoria Basin across Kenya, Tanzania, Uganda, Rwanda, and Burundi. Its mandate includes promoting trade, infrastructure development, public health, research, environmental protection, and public participation. The LVBC has led efforts like the Lakewide Inclusive Sanitation (LWIS) Strategy to address pollution and improve public health.
- Lake Tanganyika Authority (LTA): Formed in 2008 following the ratification of the 2003 Convention on the Sustainable Management of Lake Tanganyika, the LTA ensures the protection of biodiversity and sustainable management of natural resources in the Lake Tanganyika Basin. Its member states are Burundi, DRC, Tanzania, and Zambia. The LTA coordinates harmonized national fisheries policies, pollution control measures, and biodiversity conservation efforts, including managing invasive species.
- Nile Basin Initiative (NBI): Active since 1999, the NBI is a partnership of ten riparian states (including Burundi, DRC, Ethiopia, Kenya, Rwanda, Tanzania, and Uganda from the AGL region) aimed at cooperative development of the Nile River. It seeks to share socioeconomic benefits and promote regional peace and security through equitable utilization of water resources. The NBI has facilitated agreements on 30 projects with regional benefits and improved information sharing, such as early flood warnings.
- Peace Parks Initiative: In the Great Lakes region, managers of protected areas like Kibira National Park (Burundi), Virunga National Park (DRC), and Volcanoes National Park (Rwanda) are collaborating to develop transboundary initiatives. These efforts aim to harmonize policies, increase cooperation on monitoring and surveillance, and promote a culture of peace and cooperation, recognizing the shared history and common flagship species like the mountain gorilla.
5.2. Challenges in Transboundary Management
Despite these initiatives, significant challenges impede effective transboundary management in the African Great Lakes.
- Political Instability and Lack of Coordination: Recurring cycles of violence, fragile diplomatic relations, and the persistent presence of armed groups, particularly in eastern DRC, severely complicate cooperation. Security concerns and lack of government structures, especially on the DRC side, hinder adequate management of protected areas. There is often a lack of a common vision among various partners and insufficient coordination among the numerous actors involved in conservation.
- Resource Competition and Conflicting Interests: The shared nature of the lakes means resources belong to more than one country, often leading to conflicts due to differing national interests. Examples include disputes over fishing territories between Uganda and DRC and over grazing grounds in the Omo delta between Kenyan and Ethiopian communities.
- Weak Governance and Capacity Gaps: Many countries in the basin are among the poorest globally, with limited access to clean water and sanitation, and high incidences of water-related diseases. Weak technical and financial capacities, conflicting institutional interests, and a lack of continuous or standardized environmental monitoring across borders prevent data-based decision-making and effective management.
- Funding and Sustainability: Many projects aimed at ecosystem restoration are supported by short-term, externally funded initiatives, which are often not sustainable in the long run. Significant funding, estimated at $1.9 billion for Lake Victoria’s sanitation strategy alone, is needed to implement sustainable solutions.
- Human Population Pressure: High population growth rates in riparian areas exacerbate pressure on natural resources, leading to overexploitation, land degradation, and increased pollution. This demographic pressure often outpaces the capacity for sustainable management.
5.3. Successes and Best Practices
Despite the challenges, there are notable successes and best practices in regional cooperation and conservation efforts.
- Integrated Management Approaches: The Lake Victoria Basin Commission’s Lakewide Inclusive Sanitation (LWIS) Strategy exemplifies a coordinated, multi-sector approach to a complex, cross-border pollution issue, involving stakeholders from all five basin countries. Similarly, the Lake Tanganyika Authority’s Framework Fisheries Management Plan and Invasive Alien Species program demonstrate efforts to jointly monitor and manage shared resources.
- Community Engagement and Livelihood Diversification: Conservation International is supporting the establishment of “community conservation areas” in Lake Victoria, where local communities are empowered to limit human activity to help native fish recover, with incentives and financing plans. Promoting environmentally responsible aquaculture and aquaponics offers alternative livelihoods, reducing pressure on wild fish stocks. In Lake Malawi, community-led fisheries management is being introduced to protect cichlid species, empowering local committees to enforce bylaws.
- Information Sharing and Capacity Building: Organizations like African Great Lakes Inform aim to connect thousands of people working on sustainable management by providing access to spatial data, project information, and adaptive management processes. The Nile Basin Initiative has significantly improved information sharing, leading to coordinated responses like early flood warnings in Sudan and South Sudan. Capacity building for local communities, farmer and fisherman cooperatives, and engaging youth and students in conservation efforts, as seen in Lake Kivu, are crucial for long-term success.
- Transboundary Cooperation Frameworks: The twinning of lake-governance systems, such as between the Laurentian and African Great Lakes, offers opportunities for learning from each other’s mistakes and successes, fostering collaboration and information sharing among professionals and stakeholders. The establishment of the Lake Edward and Lake Albert Fisheries and Aquaculture Organizations (LEA-FAO) aims to harmonize fishing regulations between DRC and Uganda.
- Targeted Interventions: Projects like the Lake Tanganyika Research Project and Lake Tanganyika Biodiversity Project have enriched knowledge on biodiversity and fisheries, highlighting the need for joint management solutions to transboundary environmental threats. The World Bank’s Great Lakes Trade Facilitation Project aims to reduce trade costs and improve commercialization of value chains, particularly for small-scale and women traders, which can indirectly alleviate pressure on natural resources by providing alternative economic opportunities.
6. Conclusions
The African Great Lakes region is a system of profound ecological significance, economic dependence, and complex geopolitical dynamics. Its lakes are global biodiversity hotspots, supporting millions of livelihoods through fisheries, agriculture, and emerging resource extraction industries. However, this critical system is under immense and escalating pressure.
Ecological degradation, driven by pervasive pollution, unsustainable fishing practices, the proliferation of invasive species, and widespread land degradation, directly undermines the natural capital that underpins the region’s economies. The impacts of climate change act as a critical exacerbator, intensifying existing vulnerabilities and making communities and ecosystems more fragile.
Economically, the region is characterized by a paradox of abundance and vulnerability. While natural resources provide essential protein and income, the high dependence on these resources, coupled with rapid population growth and widespread poverty, often leads to overexploitation and environmental harm. The significant potential for tourism remains largely unrealized due to persistent insecurity, while resource extraction, particularly of minerals and oil, frequently fuels conflict rather than fostering equitable development.
Geopolitically, the region is marked by a history of violence and ongoing conflicts, particularly in the eastern Democratic Republic of Congo, driven by ethnic tensions, governance failures, and intense competition over strategic resources. These conflicts have devastating humanitarian consequences, including mass displacement and food insecurity, and significantly impede efforts towards sustainable development.
Effective governance and transboundary cooperation are essential but face substantial challenges, including political instability, conflicting national interests, weak institutional capacities, and insufficient long-term funding. Despite these hurdles, regional organizations and various initiatives are implementing integrated management approaches, fostering community engagement, and promoting information sharing.
Ultimately, the future of the African Great Lakes hinges on a fundamental shift towards holistic, integrated strategies that recognize the deep interdependencies between ecology, economy, and geopolitics. Addressing one dimension in isolation will prove insufficient. Sustainable development and lasting peace in this vital region require concerted, collaborative efforts that prioritize environmental protection, promote diversified and resilient livelihoods, and build robust, transparent governance frameworks to manage shared resources and resolve conflicts.
