The Great Green Wall for the Sahara and the Sahel Africa’s Commitment

Climate change affects mostly developing countries and especially those in Subsaharian Africa

The eleven below shown subsaharian countries have decided, agreed and committed in first phase, to implement a green wall, by planting trees alongside the southern edge of the Sahara Desert extended from one point (Senegal) of Africa to another (Djibouti), with intent to prevent desertification and combat climate change.

Great Green Wall for the Sahara and the Sahel

  • Length: 8.500 km
  • Width: 100 km
  • Extent: 850.000 km2
  • Plants to plant (minimum): 20 δισεκατομμύρια τεμάχια

n a second phase, or maybe contemporary, they intent to transform the entire Sahel Region, 5 million Km2, in an agroforestry area, by planting 150 billion trees, for food and fodder, combating poverty, famine, malnutrition and migration.

For better and more efficient conduct of the implementation of this purpose, they have established a pan African agency with the following data:

Name:   PAGGW – PanAfrican Agency for the Great Green Wall

Each country of the eleven above mentioned, has also established a National Agency for the Great Green Wall, which is responsible and must conduct the implementation of its part of the Great Green Wall.

AZA – Arid Zone Afforestation NPO – hereafter AZA, is continuously in contact with all these agencies discussing the cooperation conditions for the implementation of the Great Green Wall.

AZA can participate in two ways. One is to implement directly, in collaboration with other local partners and in common accord with the National Agency of every country, perpetual afforestation projects. The other one is to involve all local habitants in the implementation of the purpose by distributing and providing them with the tree planting system SAFE TREE specific models giving them the possibility to plant and grow up trees in their property or in a common area belonging to the village community.

10 million people by 100 trees means 1 billion trees.

​​​​​​​In this way AZA involves all humanity to participate in planting trees in the arid and deserted areas of the planet by financing the cost of the SAFE TREE specific models.

Scientists suggest that humanity has to plant minimum 1 trillion trees in arid and deserted areas in order to save the planet from the overwarming, but it is impossible to implement without involving all habitants in these areas.

All countries around the Sahara Desert.

Algeria, Burkina Faso, Benin, Chad, Cape Verde, Djibouti, Egypt, Eritrea, Ethiopia, Libya, Mali, Mauritania, Niger, Nigeria, Senegal, Sudan, Gambia and Tunisia.

Recently, all African countries back this purpose.

The initiative is backed by many regional and international organizations, including:

  • AUC – African Union Commission
  • EU – European Union
  • WB – World Bank
  • GM – Global Mechanism of UNCCD
  • UNCCD – United Nations Convention to Combat  Desertification
  • UNEP – United Nations Environment Programme
  • ICRAF – World Agroforestry Center
  • FAO – Food and Agricultural Organization 
  • AMU – Arab Maghreb Union
  • GEF – Global Environment Facility

And many others all over the world.


AZA invites:

  • the entire humanity to join us for the implementation of the Great Green Wall.
  • anybody everywhere in the planet, who needs and intents to plant and grow up trees in arid and deserted areas
  • to contact AZA’s team in describing his problem and explaining his intention.


Planting a tree is believing in tomorrow

Are you ready and willing to finance an afforestation - reforestation project in your dry home country?

AZA is ready to implement it successfully, or provide you with the appropriate SAFE TREE model to apply it on your own.
