The Actual History
The Sahel region—a semi-arid strip of land stretching across Africa from Senegal to Sudan, forming a transition zone between the Sahara Desert to the north and savannas to the south—has experienced severe ecological degradation over the past century. The region experienced devastating droughts in the 1970s and 1980s that claimed over 100,000 lives and displaced millions. These droughts exposed deeper environmental vulnerabilities that had been developing for decades.
Desertification in the Sahel began accelerating in the mid-20th century due to a complex interplay of natural climate variability and human activities. Colonial agricultural policies promoting export crops like peanuts and cotton had expanded cultivation into marginal lands while traditional management systems were disrupted. Post-independence governments often continued these unsustainable practices. Rapid population growth further increased pressure on natural resources, leading to overgrazing, deforestation, and shortened fallow periods.
The 1972-1974 drought became a turning point, affecting approximately 50 million people across the Sahel. It prompted the formation of the Permanent Interstate Committee for Drought Control in the Sahel (CILSS) in 1973. International aid poured in, but much of it focused on emergency food supplies rather than addressing underlying environmental issues. Subsequent droughts in 1983-1985 reinforced the region's vulnerability.
Early anti-desertification efforts in the 1970s and 1980s often relied on centralized, top-down approaches that emphasized large-scale tree planting campaigns and technical solutions designed by external experts. Many of these initiatives failed due to insufficient community involvement, inappropriate species selection, and lack of attention to traditional knowledge systems. The emphasis on creating shelterbelt plantations rather than integrating trees into agricultural systems proved particularly ineffective.
A significant shift began in the 1990s with the emergence of Farmer-Managed Natural Regeneration (FMNR), pioneered by farmers in Niger who began protecting and managing naturally occurring tree seedlings in their fields. This approach has successfully regreened over 5 million hectares in Niger alone, improving soil fertility, crop yields, and microclimate conditions.
In 2007, the African Union launched the Great Green Wall initiative, initially conceptualized as a 15km wide, 8,000km long band of trees stretching from Senegal to Djibouti. Over time, this vision evolved from a literal "wall of trees" to a mosaic of sustainable land management practices tailored to local contexts. Progress has been uneven, with success in countries like Ethiopia and Senegal, but challenges persist in conflict-affected areas like northern Mali and Chad.
By 2025, the Sahel continues to face significant climate change threats, with temperatures rising 1.5 times faster than the global average. While there have been notable successes in specific regions, desertification continues to advance in many areas. Current estimates suggest only about 15-20% of the original Great Green Wall objectives have been met, with approximately 4 million hectares restored. Despite increased international funding commitments, implementation challenges remain due to governance issues, insecurity, and the difficulty of scaling locally successful approaches across the vast region.
The Point of Divergence
What if Sahelian nations had implemented fundamentally different anti-desertification strategies following the devastating 1972-1974 drought? In this alternate timeline, we explore a scenario where the international and regional response to the Sahel crisis took a dramatically different approach—one that centered indigenous knowledge, community participation, and ecosystem-based thinking decades before these became mainstream in our timeline.
The divergence begins in 1973, when CILSS (the Permanent Interstate Committee for Drought Control in the Sahel) was formed. In our timeline, CILSS primarily focused on coordinating international aid and technical interventions. In this alternate timeline, a confluence of factors shifted the organization's approach:
One possible mechanism for this change was the greater influence of visionary ecological thinkers like René Dumont, the French agronomist who had warned about environmental degradation in Africa. In this timeline, Dumont's ideas—which emphasized working with natural processes rather than imposing external technical solutions—gained greater traction among both Sahelian leaders and international donors.
Alternatively, the divergence might have stemmed from stronger political will among newly independent Sahelian nations to assert sovereignty over their development pathways. Perhaps leaders like Thomas Sankara of Burkina Faso (who in our timeline came to power later) emerged earlier, championing self-reliance and ecological thinking.
A third possibility involves the experience of the World Bank's Kano River Project in northern Nigeria (1971-1976), which in our timeline demonstrated the limitations of large-scale irrigation approaches. In this alternate timeline, these lessons were learned earlier and more thoroughly, prompting a region-wide shift toward smaller-scale, farmer-centered strategies.
Whatever the specific trigger, by late 1974, as the drought emergency abated, the Sahelian nations together with international partners adopted a radically different framework for environmental restoration—one that prioritized:
- Indigenous ecological knowledge and traditional resource management systems
- Community-led implementation rather than external technical solutions
- Integrated approaches combining water harvesting, agroforestry, and grazing management
- Decentralized decision-making adapted to local ecological conditions
This shift represented a dramatic departure from the actual historical trajectory, where such approaches only gained significant momentum decades later. Instead, the foundations for a different ecological and social future for the Sahel were laid in the mid-1970s, just as the region began its recovery from drought.
Immediate Aftermath
Institutional Transformations (1974-1980)
The most immediate consequence of the divergence was a fundamental restructuring of environmental governance in the Sahel. Rather than creating centralized agencies staffed primarily by foreign experts, Sahelian governments established local land management committees comprised of farmers, pastoralists, and traditional authorities. These committees were given meaningful decision-making power over resource allocation and restoration priorities.
International donors, who had initially planned massive irrigation schemes and industrial agricultural projects, redirected funding toward supporting these local institutions. The United Nations Sahelian Office (UNSO) transformed from a conventional development agency into a facilitator of knowledge exchange between communities. By 1977, over 2,000 village-level committees were actively implementing land restoration projects across the region.
A critical early innovation was the revival and modernization of traditional water harvesting techniques. In northern Burkina Faso (then Upper Volta), farmers began constructing improved zaï pits—small planting holes filled with organic matter that concentrate scarce rainfall—combined with contour stone bunds to slow water runoff. These simple, low-cost techniques showed immediate benefits, rehabilitating severely degraded land within 2-3 growing seasons.
The Niger Basin Initiative (1975-1980)
Among the most consequential early programs was the Niger Basin Initiative, launched in 1975 as a collaborative effort between Niger, Mali, and Nigeria. Rather than pursuing the large dam projects that dominated our timeline's approach to the Niger River, these countries implemented a decentralized network of smaller water management systems.
The initiative pioneered what became known as the "three-tier approach": combining micro-catchment techniques at the field level, small earth dams at the village level, and coordinated seasonal flooding strategies at the watershed level. By 1980, this system had increased dry-season farming opportunities for approximately 220,000 smallholder farmers while maintaining seasonal wetlands critical for biodiversity and pastoralist livelihoods.
President Seyni Kountché of Niger, who had initially favored conventional agricultural modernization, became an unexpected champion of these approaches after witnessing early successes. His famous 1977 speech in Maradi—where he declared "the future of our nation lies not in mimicking foreign models but in rediscovering our ancestors' wisdom about living with drought"—marked a significant departure from the modernization paradigm that dominated development thinking in our timeline.
Early Research and Innovation Networks (1976-1982)
A distinctive feature of this alternate timeline was the early emergence of farmer-researcher partnerships. In 1976, the Sahelian Center for Adaptive Agricultural Research was established in Niamey, with satellite centers in each Sahelian country. Unlike conventional agricultural research stations, these centers operated on a novel principle: farmers themselves identified research priorities and participated directly in field trials.
This participatory approach accelerated the identification and dissemination of drought-resistant crop varieties and effective agroforestry systems. By 1980, researchers and farmers had cooperatively developed improved techniques for managing naturally regenerating trees on farmland—similar to the Farmer-Managed Natural Regeneration (FMNR) that emerged decades later in our timeline. This approach spread rapidly through farmer-to-farmer exchange visits, with over 500,000 hectares under improved management by 1982.
Policy Reforms and Land Tenure (1978-1983)
The participatory restoration movement soon confronted a fundamental obstacle: colonial-era land laws that discouraged long-term investment in land restoration. Between 1978 and 1983, most Sahelian countries enacted significant land tenure reforms that recognized customary rights while encouraging sustainable management.
Senegal led the way with its 1978 Rural Community Land Act, which devolved management authority to local communities while maintaining state ownership of land. The act included innovative provisions recognizing "restoration rights"—giving individuals and communities secure tenure over degraded lands they had rehabilitated. Mali, Niger, and Upper Volta (later Burkina Faso) implemented similar reforms by the early 1980s.
These reforms created powerful incentives for land restoration, as farmers gained confidence that they would benefit from long-term investments in soil health and tree cover. A 1983 assessment found that areas with secure community land rights showed 40-60% higher adoption rates of restoration techniques compared to regions where land tenure remained uncertain.
Responding to the 1983-1985 Drought
When a second severe drought struck the region in 1983-1985, areas that had implemented the new approaches showed significantly greater resilience. Villages in central Mali that had established water harvesting systems maintained approximately 50-70% of normal crop production, while those without such systems often experienced complete crop failure.
The contrast provided powerful evidence of the effectiveness of the alternative approach. During a regional conference in Ouagadougou in 1985, government officials and development partners committed to accelerating and expanding the community-led restoration model, setting ambitious targets for the next decade and securing increased international funding based on demonstrated successes.
By the mid-1980s, the initial response to the 1970s drought had evolved into a comprehensive alternative development pathway for the Sahel—one centered on ecological restoration, community management, and climate resilience. The foundations had been laid for a dramatically different trajectory than what unfolded in our actual timeline.
Long-term Impact
Ecological Transformation (1985-2005)
The decades following the initial implementation of alternative anti-desertification strategies witnessed a profound transformation of the Sahelian landscape. By the early 1990s, satellite imagery began detecting significant increases in vegetation cover across large portions of the region. Unlike the limited "pockets of green" that characterized our timeline, this alternate Sahel experienced widespread ecological recovery.
The most dramatic changes occurred in the "Middle Sahel" belt, where annual rainfall ranges from 300-600mm. By 2000, approximately 15 million hectares had been restored through a mosaic of techniques:
-
Traditional Forestry 2.0: Rather than plantation-style reforestation, communities practiced "assisted natural regeneration," protecting naturally occurring seedlings of native species like Faidherbia albida, Balanites aegyptiaca, and Acacia senegal. These species, selected for their multiple benefits (soil improvement, fodder, food, medicine), increased tree density from fewer than 10 trees per hectare to 40-60 trees per hectare on agricultural lands.
-
Integrated Water Management: Networks of half-moon microcatchments, stone bunds, and small earth dams transformed hydrology at landscape scales, slowing water flow and increasing infiltration. Groundwater levels, which had been declining for decades, began to recover in many regions by the late 1990s. Seasonal streams that had been dry since the 1960s began flowing again in parts of Burkina Faso and Mali.
-
Soil Regeneration: The combination of water harvesting and increased organic matter from trees progressively rebuilt soil fertility. Studies conducted in 2003 found that restored areas showed 2-4 times higher soil carbon levels compared to non-restored areas, creating a virtuous cycle of improved water retention and biological activity.
By 2005, the Sahelian "re-greening" had become a global environmental success story. Approximately 65% of the degraded lands identified in the 1970s had undergone significant recovery—a stark contrast to our timeline, where desertification continued to advance in many areas despite isolated successes.
Agricultural Transformation and Food Security (1990-2010)
The ecological restoration fundamentally transformed Sahelian agriculture. Rather than pursuing the Green Revolution model that dominated our timeline (characterized by monocultures, synthetic inputs, and irrigation), Sahelian farmers developed a distinctive agroecological approach suited to their variable climate.
This "Sahelian Agroecological System" was characterized by:
-
Biodiversity at Multiple Levels: Farmers maintained diverse portfolios of crops, varieties, and field types as a risk management strategy. A typical farm might include drought-resistant cereals (millet, sorghum), legumes (cowpea, groundnut), vegetables in lowland areas, and dozens of useful tree species providing fruits, medicines, and livestock fodder.
-
Integrated Crop-Livestock Systems: Rather than separating pastoral and farming activities (which deepened resource conflicts in our timeline), this system integrated them. Nomadic herders developed formal agreements with farming communities for managed grazing of crop residues, with livestock providing manure in return.
-
Adaptive Management: Farmers developed sophisticated systems for adjusting planting patterns based on seasonal rainfall forecasts, often combining modern meteorological information with traditional weather indicators.
The cumulative impact on food security was substantial. By the early 2000s, Sahelian countries had largely eliminated the chronic food deficits that characterized our timeline. When the severe drought of 2005 struck the region, most areas maintained 60-75% of normal production—a dramatic improvement over similar drought years in our timeline, where production often fell below 30% of normal levels.
A 2006 comparative study found that farmers using the integrated agroecological approach earned 40-80% higher and more stable incomes than those using conventional approaches, primarily due to reduced input costs, greater resilience to rainfall variability, and income diversification through tree products.
Demographic and Social Impacts (1990-2020)
The altered ecological trajectory had profound consequences for Sahelian demographics and social dynamics:
-
Modified Demographic Transition: While population growth remained high, it began declining earlier than in our timeline. By 2010, fertility rates in rural areas had fallen to approximately 5.0 children per woman (compared to 6.5-7.0 in our timeline). Researchers attributed this partly to improved food security and decreased child mortality, but also to women's increased economic opportunities in restoration activities and agroforestry value chains.
-
Reduced Rural Exodus: Unlike our timeline, where environmental degradation accelerated rural-to-urban migration, the restoration economy created viable livelihoods in rural areas. Urban growth continued but at a more moderate and manageable pace. By 2015, approximately 45% of the Sahelian population lived in urban areas, compared to 55% in our timeline.
-
Transformed Rural Governance: The community natural resource management committees evolved into sophisticated local governance institutions. By the early 2000s, these committees had expanded beyond environmental management to broader development planning, effectively creating a new tier of participatory governance below the formal municipal level.
-
Reduced Resource Conflicts: The integrated management of agricultural and pastoral resources significantly reduced the farmer-herder conflicts that have destabilized many Sahelian regions in our timeline. Formal resource-sharing agreements, combined with clearly demarcated transhumance corridors and dry-season grazing reserves, created institutional frameworks for managing the inevitable tensions between different land users.
Economic Development Trajectory (2000-2025)
By the 2000s, the alternative development pathway had generated distinctive economic structures quite different from our timeline:
-
Green Value Chains: Rather than focusing primarily on mineral extraction and export agriculture, Sahelian economies developed sophisticated value chains around indigenous products and ecosystem services. The shea butter industry in Burkina Faso, for example, evolved into a $500 million annual export sector by 2015, with processing increasingly occurring within the country rather than merely exporting raw materials.
-
Ecological Tourism: The regenerated landscapes attracted growing numbers of both African and international tourists interested in the region's unique ecology and cultural heritage. By 2020, eco-tourism contributed approximately 8-12% of GDP in countries like Senegal and Burkina Faso, compared to less than 3% in our timeline.
-
Carbon Finance: The Sahel became an early leader in carbon sequestration projects. Beginning with pilot programs in the early 2000s, by 2015 Sahelian countries were earning over $300 million annually from carbon payments, with revenues primarily flowing to the communities implementing restoration activities.
-
Renewable Energy Hub: The decentralized development model facilitated early adoption of distributed renewable energy. By 2020, approximately 70% of rural Sahelian communities had access to solar power (compared to 20-30% in our timeline), supporting small-scale productive activities and reducing pressure on woodlands for fuel.
Geopolitical Implications (2010-2025)
The alternative development trajectory significantly altered the Sahel's geopolitical position:
-
Regional Stability: The reduced environmental degradation, stronger rural governance systems, and more equitable resource management curtailed many of the drivers of instability that afflict the region in our timeline. While the Sahel still faced security challenges, particularly from international terrorist networks, these remained more contained and less embedded in local grievances.
-
Climate Leadership: By the 2010s, Sahelian countries had emerged as influential voices in international climate negotiations. Their successful large-scale restoration experience provided a powerful model for other dryland regions facing similar challenges. The "Sahelian Approach" to climate adaptation became internationally recognized, with Sahelian experts frequently advising countries in Asia, Latin America, and elsewhere in Africa.
-
Development Paradigm Influence: The Sahelian experience challenged conventional development wisdom about the necessity of following Western industrialization patterns. By demonstrating that ecological restoration could serve as a foundation for economic development, Sahelian countries influenced development thinking far beyond their borders.
By 2025, the Sahel in this alternate timeline, while still facing significant challenges, presented a stark contrast to our own timeline. Rather than being viewed primarily as a zone of crisis, drought, and conflict, it had become recognized as a global leader in climate-resilient development and ecological restoration—a profound transformation stemming from different decisions made half a century earlier.
Expert Opinions
Dr. Aminata Diallo, Professor of Environmental Governance at the University of Ouagadougou, offers this perspective: "What's most striking about this alternate trajectory is not just the ecological outcomes, but the institutional transformation it catalyzed. By placing communities at the center of restoration efforts rather than as mere recipients of technical solutions, the approach fundamentally altered power relationships between citizens, governments, and international actors. The 'restoration committees' became incubators for a new kind of participatory governance that eventually influenced political systems more broadly. I believe this helps explain why this alternate Sahel experienced more stable democratic transitions than we've seen in our own timeline—environmental restoration became a school for democratic practice."
Professor James Wilson, Environmental Historian at Oxford University, provides a more cautionary assessment: "While the ecological and social achievements in this alternate Sahel are impressive, we shouldn't romanticize the outcome as some kind of pastoral utopia. Significant challenges would have persisted, particularly around gender equity, intergenerational resource conflicts, and the tension between conservation and development objectives. Moreover, the Sahel would still have faced external pressures from climate change, global market fluctuations, and regional security threats. What's distinctive about this timeline is not the absence of problems, but the enhanced capacity of local institutions to navigate these challenges through more resilient ecological and social systems. In essence, the different trajectory didn't eliminate vulnerability—it transformed it from acute crisis to manageable stress."
Dr. Mohammed Al-Hassan, Director of the African Climate Resilience Institute, examines the climate implications: "The most profound long-term impact of this alternate pathway may be its contribution to regional and global climate regulation. Our models suggest that the extensive landscape restoration—15+ million hectares by 2020—would have measurably altered regional rainfall patterns through increased evapotranspiration and modified surface albedo. This could have partially counteracted the precipitation declines associated with global climate change, creating a more favorable hydrological cycle than what we're experiencing in our timeline. Given recent research on climate tipping points, it's not implausible that such large-scale vegetation recovery could have helped maintain West African monsoon stability, with cascading benefits for agriculture across the wider region. This illustrates how human management of landscapes can either amplify or moderate global climate change impacts at regional scales."
