সাহারা মরুভূমিকে থামাতে ৮,০০০ কিমির সবুজ দেয়াল! আফ্রিকার এই মহাপরিকল্পনার আসল রহস্য

Africa is building the Great Green Wall — an ambitious project stretching nearly 8,000 kilometers across the continent to fight the spread of the Sahara Desert. But can millions of trees really stop desertification? In this documentary, we explore how the Great Green Wall is being built, why millions of trees failed in the beginning, and how ancient farming techniques like Zai pits, half-moons, and stone bunds are helping restore the land. We also uncover the incredible story of Yacouba Sawadogo, the farmer who transformed barren land into a thriving forest. With a massive $50 billion vision and a goal of restoring 100 million hectares of land, the Great Green Wall could become one of humanity's biggest battles against desertification and climate change. But there is one big question — can Africa restore the remaining 82 million hectares before the Sahara's advance threatens even more land and communities? #GreatGreenWall #SaharaDesert #Africa #Desertification #ClimateChange #Documentary #Sahara ⚠️ COPYRIGHT DISCLAIMER This video is intended for educational, informational, and documentary purposes only.
