Baobab trees flourish in the dry and semi-dry regions of Africa, carrying significant cultural and ecological value. Some of these majestic trees have been around for thousands of years. Recently, global demand for baobab products has surged, attributed to the numerous nutritional and health advantages of its fruit.
However, this escalating demand presents several challenges, leading to serious concerns about the sustainability of these ancient giants. Patrick Maundu, who participates in a research initiative focused on preserving the baobab’s heritage in Kenya, provides insights on ways to protect these trees for future generations.

Where are baobabs located?
The baobab is native to at least 37 countries in Africa and two in the Arabian Peninsula. The African baobab (Adansonia digitata) is the most widespread among the eight recognized species. It thrives in some of the harshest environments, ranging from salty coastlines to vast dry savannas and forests. The other species include six endemic to Madagascar and one located in northern and western Australia.
These trees are extraordinary for their resilience; some have survived for over 2,000 years. Their capacity to store water in their enormous trunks, which can exceed 10 meters in circumference, helps them endure extended periods of drought. Their trunks can quickly regenerate after being damaged by human activities or animals, such as elephants that may damage them while seeking water.
Unlike most trees festooned with foliage, baobabs frequently remain bare for much of the year. Their stout, leafless branches spread out like skeletal arms, presenting a surreal and almost enchanting appearance.
Baobabs exhibit a slow growth rate, typically beginning to bloom and yield fruit around the age of 20. However, in arid regions, they often don’t produce fruit until they reach about 60 years old.
Why is the baobab significant?
In African culture, every part of the baobab tree is beneficial.
The leaves serve as a nutritious vegetable, while the tangy fruit pulp enhances various foods and drinks. Baobab pulp is rich in antioxidants, vitamins (particularly C and B complex), fiber, and essential minerals such as calcium, iron, and magnesium.
The seeds yield oil used in cosmetic products. The inner bark is collected for its fibers, which are woven into ropes and baskets. The hollows in the trunk provide habitats for honey bees. Furthermore, the fruit shells can be transformed into utensils and household items. Extracts from the baobab’s bark and roots are commonly employed in traditional medicine.
Due to its significant contributions, the baobab features prominently in various folklore and myths. Many African communities hold the tree in high regard, often linking it to spiritual beliefs, and conducting various ceremonies and rituals in its presence.
From an ecological perspective, the baobab is essential to the ecosystem, supporting a wide range of wildlife, including fungi, insects, birds, reptiles, bats, and monkeys. Its substantial trunk acts as a water reservoir, and its intricate root system helps stabilize the soil, reducing erosion. The leaves that fall enrich the soil with nutrients.
Additionally, the baobab functions as a carbon sink, absorbing carbon dioxide from the atmosphere, thereby contributing to the fight against climate change.
What is driving the increasing global demand for baobabs?
The baobab is being recognized as a superfood. This trend gained significant traction when the European Union and the U.S. Food and Drug Administration acknowledged baobab pulp as a food ingredient in 2008 and 2009, respectively. This recognition paved the way for its use in beverages, foods, natural remedies, and beauty products.
Zimbabwe has emerged as a leader in this growing industry, strategically targeting the lucrative European market.
What challenges does the tree face?
Various factors threaten the baobab tree. Its slow growth, immense size, long lifespan, and economic significance make it susceptible to numerous risks. While some baobab species from Madagascar are classified as critically endangered or endangered, the African baobab is currently not under such designation. Nevertheless, evidence suggests that certain unique populations could be declining in several African regions, indicating a need for enhanced conservation efforts.
Climate change is affecting the ecosystems that baobabs rely upon, as they require specific soil and air humidity conditions and depend on specialized pollinators like bats and bush babies for reproductive processes. The rise in temperatures and shifts in rainfall patterns disrupt these fragile balances, impacting the trees’ health and reproductive capabilities.

Furthermore, changes in community values and beliefs are altering attitudes towards the baobab. As modernity progresses, the tree’s hallowed status is waning in some groups, leading to its perception as an antiquated relic. Additionally, the substantial canopy and roots of the tree compete with food crops in the context of diminishing agricultural land, increasing the likelihood of communities cutting them down.
The increase in commercial interest represents a double-edged sword. The rising demand for baobab pulp raises critical concerns regarding natural regeneration, genetic diversity loss, and the overall health of baobab populations. Many baobabs continue to be harvested using rudimentary methods—such as knocking the fruits down or climbing on pegs attached to the trunk—resulting in harm to the trees.
Additionally, this newfound commercial focus has introduced another threat: biopiracy. A notable case occurred in Kenya in 2022, where entire baobab trees were controversially uprooted and shipped to Georgia in Eastern Europe. Although eight trees were exported, they subsequently died, highlighting insufficient prior research regarding their adaptability to a new habitat.
This incident revealed the lack of strong policies and regulations needed to safeguard these crucial trees from exploitation and underscored the urgent need for specific measures to ensure the preservation of the baobab.
What measures should be taken?
Protecting the baobab requires more than isolated initiatives.
This involves a combination of community-driven protection, conservation strategies, and management actions on the local level. Additionally, it demands strategic policy frameworks and collaborative efforts at both national and international levels.
These policies should advocate for livelihood programs for local communities by improving value chains and creating market links for baobab products. Promoting sustainable harvesting practices, such as leaving enough fruit for regeneration, will help preserve both the trees and their ecosystems. Integrating indigenous knowledge with modern tools, such as genetic research, will reinforce these initiatives.
