Researchers in Eastern Ethiopia studied 42 different wild plants that local people eat to understand how these plants help communities survive, especially during tough times. They talked to 64 local people over a year to learn which plants they use, when they harvest them, and how they prepare them. The study found that fruits and leaves from plants like fig trees and jujubes are the most popular foods. The research shows these wild plants are important for feeding families and keeping cultural traditions alive, but they’re threatened by activities like cutting firewood and overgrazing. The researchers suggest protecting these plants by growing them in home gardens and involving communities in conservation efforts.

The Quick Take

  • What they studied: Which wild plants people in Eastern Ethiopia eat, how they use them, when they’re available, and what threatens these plants
  • Who participated: 64 people from communities living near Karamara forest patches in Eastern Ethiopia, selected to represent different ages, genders, and levels of experience with wild plants
  • Key finding: Researchers documented 42 different wild edible plant species that local people use regularly. Fruits are the most commonly eaten part (69% of uses), followed by leaves (14%). Three plants—amaranth, fig trees, and jujubes—were the most preferred by the community.
  • What it means for you: If you live in or work with communities in dryland regions, understanding local wild plants could improve food security and nutrition. However, these plants need protection from threats like overgrazing and excessive firewood collection. This research suggests growing these plants in home gardens as a practical solution.

The Research Details

This was a cross-sectional ethnobotanical study, which means researchers collected information from people at one point in time (over a 12-month period from February 2023 to January 2024) rather than following them over many years. The researchers used multiple methods to gather information: they conducted one-on-one interviews with 64 carefully selected community members, held group discussions to understand shared knowledge, visited local markets to see which plants were being sold, and took guided walks through the forest with local experts to identify and collect plant samples.

The researchers selected their participants using purposive sampling (choosing people they knew would have good knowledge) and snowball sampling (asking participants to recommend other knowledgeable people). This approach helped them find the people most familiar with wild plants in the area. They collected actual plant specimens and verified their identification using scientific databases to ensure accuracy.

The study analyzed the data by calculating how often each plant was mentioned (Relative Frequency of Citation), ranking preferences, and using statistical tests to see if knowledge differed between groups based on gender, age, education level, and experience with plants.

This research approach is important because it combines local knowledge with scientific documentation. By talking directly to community members and collecting actual plant specimens, the researchers created a reliable record of which plants are important for food security. This type of study is especially valuable in regions where traditional knowledge hasn’t been formally documented, and it helps ensure that valuable cultural information isn’t lost.

Strengths of this study include the year-long data collection period (capturing seasonal variations), the use of multiple information-gathering methods, and verification of plant identification through scientific databases. The study involved 64 participants, which is a reasonable sample size for this type of qualitative research. However, the study is limited to one specific forest area, so results may not apply to other regions. The researchers relied on people’s memories and reports rather than direct observation of all plant uses, which could introduce some inaccuracy. Additionally, the study doesn’t include nutritional analysis of the plants, so we don’t know exactly how nutritious they are.

What the Results Show

The researchers documented 42 different wild edible plant species belonging to 32 different plant genera and 24 plant families. Shrubs made up 50% of these species, trees made up 33.3%, and herbs made up the remainder. Fruits were by far the most commonly eaten part of plants (69% of all uses), followed by leaves (14%), seeds, and other parts.

Three plants stood out as the most preferred by the community: amaranth (a leafy green vegetable), fig trees (which produce sweet fruits), and jujubes (small fruits similar to dates). These plants were preferred because they were nutritious, tasty, and reliably available. The knowledge about these plants varied significantly between different groups of people—men and women had different knowledge, older people knew more than younger people, and people with more experience using wild plants had deeper knowledge than those with less experience.

The study found that these plants were available at different times of year, and communities had developed strategies for harvesting and storing them to use throughout the year. Some plants were sold in local markets, providing income for families. The researchers identified major threats to these plants, including cutting trees for firewood, making charcoal, overgrazing by livestock, and drought conditions that are becoming more common in the region.

The research revealed that communities had developed sophisticated knowledge about which plants to harvest when, how to prepare them, and how to store them for later use. This seasonal knowledge is crucial for food security in a region where food availability varies throughout the year. The study also found that some wild plants were being commercialized in local markets, suggesting they could provide economic benefits beyond just feeding families. Community members recognized the importance of protecting these plants and suggested practical solutions like growing them in home gardens near houses, which would make them easier to access and help preserve them.

While the abstract doesn’t directly compare this study to previous research, the finding that wild plants are crucial for food security in dryland regions aligns with what other researchers have found in similar African communities. The emphasis on documenting indigenous knowledge before it’s lost reflects a growing recognition in the scientific community that traditional ecological knowledge is valuable and at risk of disappearing. The suggestion that home gardens could help conserve wild plants is consistent with successful conservation approaches used in other parts of Africa and Asia.

This study focused on only one forest area in Eastern Ethiopia, so the results may not apply to other regions with different climates or plant communities. The researchers relied on people’s reports about plant use rather than directly observing how plants were actually used, which could lead to some inaccuracy. The study didn’t analyze the nutritional content of the plants, so we don’t have scientific data about exactly how nutritious they are. Additionally, the study was conducted over one year, which may not capture variations that occur over longer time periods. The researchers also didn’t investigate the safety of consuming these plants or their potential medicinal properties, which would be important information for people considering using them.

The Bottom Line

Based on this research, communities in dryland regions should consider: (1) documenting and preserving local knowledge about wild edible plants before it’s lost, (2) protecting wild plant populations from overgrazing and excessive harvesting, (3) growing wild edible plants in home gardens as a practical conservation strategy, and (4) supporting the commercialization of these plants in local markets to provide economic benefits. These recommendations have moderate confidence because they’re based on community input and observed practices, though they would benefit from additional research on the nutritional and safety aspects of these plants.

This research is most relevant to: communities living in dryland regions of Africa who depend on wild plants for food; agricultural and conservation organizations working in these areas; policymakers developing food security and conservation strategies; and researchers studying traditional ecological knowledge. People living in developed countries with reliable food systems may find this research interesting from a cultural and conservation perspective, but it’s less directly applicable to their daily lives. However, the principles about preserving traditional knowledge and sustainable use of plant resources have broader relevance.

If communities implement the suggested conservation strategies, like growing wild plants in home gardens, they could see benefits within one growing season (3-6 months). Improvements in food security and nutrition would likely become noticeable within 6-12 months as families have more consistent access to these plants. Broader ecosystem benefits from reduced pressure on wild plant populations would take longer—likely 2-5 years—to become apparent.
