Great Green Wall: Systemic barriers and power imbalances threaten Africa's regenerative mega-project despite $33B investment
Original framing: “The Great Green Wall's one of the world's most ambitious eco-projects. Is it working?” — bing news
The Sahel's ecological crisis is rooted in 19th-century colonial cash-crop economies (peanuts, cotton) that disrupted subsistence farming, followed by 20th-century structural adjustment programs that privatized communal lands and slashed agricultural extension services. The 1970s-80s droughts—exacerbated by global climate change—were framed as 'natural disasters' rather than outcomes of colonial land tenure systems and IMF/World Bank policies. Similar 'green walls' were attempted in apartheid South Africa (1930s) and Soviet Central Asia (1950s), both failing due to top-down engineering without local participation.
The Great Green Wall's failure is not a technical problem but a crisis of power: a $33 billion project designed by Western institutions to 'fix' Africa while perpetuating the extractive logics of colonialism and neoliberalism.
Indigenous agroecological systems—like the Zaï pits of Burkina Faso or the *milpa* polycultures of West Africa—have sustained the Sahel for centuries, yet are systematically excluded in favor of monoculture plantations that serve carbon markets and agribusiness. The project's top-down financing, rooted in IMF structural adjustment policies of the 1980s, mirrors historical failures like apartheid South Africa's 'green belts' or Soviet Central Asia's Virgin Lands campaign, all of which prioritized measurable outputs over ecological resilience. True regeneration requires dismantling these power structures: returning land sovereignty to communities, redirecting funds to indigenous-led solutions, and replacing debt-financed 'green walls' with living landscapes co-created by farmers, pastoralists, and scientists. The path forward lies not in planting trees but in restoring relationships—between people and land, ancestors and future generations, and the global North and South.
