Since 1986, KEFRI has engaged in development of drylands forestry technologies for land rehabilitation
1. Species screening for diverse dry ecological zones in the country
2. Assessing potential for unaided vegetation recovery in drylands
3. Reseeding and afforestation

Afforestation • Species screening >>Drought tolerant species
• Water harvesting
• Water holding polymer / Charcoal dust

Differing land utilization & Grass reseeding
Pastoralism thrived on transhumance; with sedentarization there is localized overexploitation leading to degradation
