Both projects, currently underway, are intersectional initiatives involving governments from different countries, civil society organisations, and both individual volunteers and organised groups, guided by the idea of a unified response to global environmental issues through wildlife restoration. It is a large-scale, infrastructural application of a 'green' or 'wildlife corridor': a linear strip of vegetation or natural landscape that connects fragmented ecosystems and wildlife populations separated by human development on a continental scale. + 2In Africa, the Great Green Wall of the Sahara was launched by the African Union in 2007, with the ambition to grow an 8,000km-wide band across the continent's Sahel region. The Chinese initiative, on the other hand, goes back to 1978 with the Three-North Shelterbelt Program (TNSP), a long-term ecological restoration initiative addressing desertification, soil erosion, and wind erosion across the country's northeast, north, and northwest regions.
