About CI-340 Handheld Photosynthesis System
Analyze changes in photosynthetic activity under environmental stressors such as drought, heat & contamination.
Gas exchange measurements of trees and soil inform understanding of forest ecosystem health.
When drought takes hold in the Horn of Africa, the warning signs start below ground, out of sight and, until recently, out of reach. At Haramaya University’s Africa Center of Excellence for Climate‑Smart Agriculture & Biodiversity Conservation, PhD candidate and Assistant Professor Ephrem Mamo Weledekidane set out to change that. His goal: to watch roots…
