Imagine a tree once celebrated as a hero, now wreaking havoc on an entire region. Ethiopia’s battle with the invasive prosopis tree is a stark reminder of how good intentions can go terribly wrong. What was once a solution to desertification has become a nightmare, choking livelihoods, devastating ecosystems, and pushing communities to the brink of poverty. But here’s where it gets controversial: could this crisis have been avoided, or is it a cautionary tale of nature’s unpredictability?
In the 1970s, the prosopis tree, native to Latin America, was introduced to Ethiopia’s northeastern Afar region as a heat-resistant, fast-growing solution to soil erosion and a way to cool the arid micro-climate. Initially, it seemed like a miracle plant. But today, its thorny branches stretch up to 10 meters high, dominating vast plains and draining the soil of vital moisture. Each tree consumes up to seven liters of water daily through its deep roots, crippling agriculture and leaving farmers like Khadija Humed in despair. “Because of this plant, we have become poor,” she laments. Her story is not unique; entire communities are suffering.
And this is the part most people miss: the prosopis tree doesn’t just harm the land—it’s devastating livestock too. Its pods sicken cows, blocking their mouths and stomachs, leading to fatal losses. Khadija, who once thrived with 50 to 100 cattle, now struggles with just 10 cows and a handful of goats. The tree’s dense foliage has also attracted predators like lions and hyenas, which were rarely seen before. “We never had wild animal attacks until prosopis spread,” says 76-year-old Yusuf Mohammed. Its poisonous thorns further weaken livestock, leaving them unable to forage for food.
The economic toll is staggering. Globally, invasive species cost local economies $423 billion annually, according to a 2023 report—equivalent to Denmark’s entire GDP. In Afar alone, prosopis has cost $602 million over three decades, nearly four times the region’s annual budget. The tree now covers 20,000 square kilometers of Afar and is spreading to neighboring regions like Amhara and Oromia. By 2060, it could occupy 22% of Ethiopia’s land, according to the Journal of Environmental Management. Camels, which eat and spread its pods, have inadvertently become agents of its invasion.
Efforts to control the spread are underway. Since 2022, CARE International, supported by Danish fund Danida, has encouraged locals to harvest the plant and replace it with fruit orchards. But is it enough? “We can’t tackle it alone,” Mohammed insists. The question remains: Can Ethiopia reclaim its land, or is the prosopis tree here to stay? What do you think? Is this a problem of mismanagement, or an unavoidable consequence of introducing foreign species? Share your thoughts in the comments—let’s spark a conversation about this ecological crisis.
