介绍： 非洲的绿色长城失败了吗？

 绿色长城 "是有史以来最雄心勃勃的环保项目之一，它将在 2030 年前建成一条横跨非洲的巨大植被带，从大西洋沿岸的塞内加尔一直延伸到红海沿岸的吉布提。

它被誉为非洲应对气候变化的贡献，可以扭转干旱、过度放牧和农业技术落后造成的破坏。位于撒哈拉沙漠边缘的 11 个萨赫勒国家的重新绿化将创造数百万个就业机会，提高粮食安全，减少冲突和移民。

该计划由非洲联盟于 2007 年发起，尽管达成了政治共识，但到 2021 年，绿色长城只完成了 4%。那么，到底出了什么问题？吸取了哪些经验教训？改变战略能否确保在本十年结束时取得成功？

Is Africa’s Great Green Wall failing?

 The Great Green Wall is one of the most ambitious environmental projects ever conceived, creating a vast belt of vegetation spanning Africa by 2030; from Senegal on the Atlantic to Djibouti on the Red Sea.

It was heralded as Africa’s contribution to the fight against climate change, reversing damage caused by drought, overgrazing and poor farming techniques. The regreening of 11 Sahel countries on the edge of the Sahara Desert would create millions of jobs, boost food security, and reduce conflict and migration.

The plan was launched by the African Union in 2007, and despite political consensus, only 4% of the Great Green Wall had been completed by 2021. So what has gone wrong? What lessons have been learned, and will a change of strategy ensure its success by the end of the decade?
