Balanced reforestation from Sahel to Sahara

A 35-year plan that restores land, protects desert ecosystems, and builds a self-sufficient water cycle.

2025–2060 500 billion trees 650 million ha 55% of territory reforested

The Story

The Sahel is pushing south. Soil is losing fertility, food security is fragile, and climate-driven migration is rising. Sahel Trigger answers with a phased reforestation that moves north in bands, protecting the desert while restoring the lands that can recover.

The Problem

  • Desertification across the Sahel–Sahara region
  • Expanding arid lands and soil degradation
  • Food insecurity and migration pressures

The Solution

  • Progressive, balanced reforestation
  • 500 billion trees across 650 million hectares
  • 35 years of continuous work (2025–2060)

Step-by-Step Progression

2030–2035
Central Sahel · 400–600 trees/ha → Moisture retention
2035–2040
Northern Sahel · 500–700 trees/ha → Local microclimates
2040–2050
Southern Sahara transition · 300–500 trees/ha → Climate modification
2050–2060
Consolidation & expansion · 400–600 trees/ha → Water self-sufficiency

Ecological Balance

55% Reforested

  • Central and northern Sahel
  • Southern Sahara transition zones
  • Green corridors for soil restoration and CO2 capture

45% Protected

  • Central Sahara, hyper‑arid zones
  • Desert ecosystems and nature reserves
  • Preservation of unique biodiversity

Water Self‑Sufficiency Cycle

  1. Initial planting: minimal irrigation, drought‑resistant species.
  2. Maturation: trees improve infiltration, reduce evaporation, increase humidity.
  3. Self‑sufficiency: evapotranspiration and rainfall create an autonomous cycle.

Challenges

  • 35 years of continuous work
  • Initial water needs for young plants
  • Species selection for arid climate
  • Protection from overgrazing and fires
  • Massive but progressive investment

Solutions

  • 5‑year progression bands
  • Initial drip irrigation
  • Assisted natural regeneration
  • 45% territory protected as natural zones
  • Local community involvement

Together, balanced reforestation of the future

Reforestation alone is not enough. It must go hand‑in‑hand with emissions reduction and the protection of desert ecosystems. Sahel Trigger is a long‑term, realistic pathway to restore land while preserving what makes the Sahara unique.
