The sun rises over the vast savannas of Lumo Conservancy in Taita Taveta, casting a golden glow across the horizon. Elephants move calmly across the rangelands, leaving soft footprints in the soil. Nearby, antelopes and other herbivores feed in groups, nibbling at the tough grasses. The land, though alive, bears the marks of a harsh climate scarred by heat and irregular rains. Yet just beneath the open-cracked soil is a hidden network, a secret force of life that continues to perpetuate life in a chaotic paradigm of failure even at a time when everything else fails. This hidden life is arbuscular mycorrhizal fungi (AMF). These fungi live in the soil and form a symbiotic relationship with plants. You may not see them, but their impact is clear. Without AMF, many plants would struggle to survive in the tough conditions of the rangelands.

The recent establishment of a mid-infrared (MIR) spectroscopy laboratory at the National Agricultural Research Institute (NARI) in the capital city of Banjul is set to bring wide-reaching benefits to decision-making by providing inclusive and fast analysis compared to conventional laboratory techniques. MIR offers a faster, more inclusive and cost-effective way to analyse soil health, enabling large-scale projects, including national surveys and supporting sustainable farming and landscape restoration.

The MIR lab in The Gambia is part of a growing network led by CIFOR-ICRAF’s Soil-Plant Spectral Diagnostics Laboratory in Nairobi, which has pioneered dry spectral soil analysis across Africa since 2009.
