Local perception on the importance of vegetation and Icacina senegalensis in Senegal: Case of Groundnut Basin, Casamance and Eastern Senegal agroecological zones
This study assesses local communities' perceptions across three agroecological zones in Senegal, revealing that while vegetation is primarily valued for provisioning services like food, fodder, and medicine—with *Icacina senegalensis* being a key medicinal species—people recognize a general decline in vegetation abundance and propose reforestation and protection as essential management strategies.

Imagine Senegal's landscape as a giant, living pantry and pharmacy. For the people living there, the plants aren't just scenery; they are the shelves holding their food, the medicine cabinet for their families, and the roof that shields them from the sun. This study is like a conversation with the "head chefs" and "head doctors" of three different neighborhoods in Senegal to ask: "What's in the pantry? How is the food supply doing? And what's your favorite ingredient?"
Here is the breakdown of what the researchers found, using simple analogies:
1. The Three Neighborhoods (The Study Areas)
The researchers visited three distinct "neighborhoods" (agroecological zones) in Senegal:
- The Groundnut Basin: A dry, semi-arid area.
- Eastern Senegal: A mix of sandy and fertile soils.
- Casamance: A lush, tropical area in the south.
They talked to 202 families across these areas, asking them about the plants around them, specifically focusing on a special plant called Icacina senegalensis (let's call it the "Senegal Tuber").
2. The "Big Three" Services (What the Plants Do)
When asked what the plants provide, the locals gave a clear answer, much like ranking the most important items in a survival kit:
- The Pantry (Provisioning Services - 91%): This is by far the most important. The plants provide food for humans, feed for animals, and medicine. It's the main reason people rely on the vegetation.
- The Shield (Regulating Services - 8%): These plants act as natural umbrellas (shade), windbreaks to stop dust, and soil protectors.
- The Spirit (Cultural Services - 0.5%): A tiny fraction of people mentioned plants used for spiritual protection or rituals.
The Hierarchy of Needs:
Even though plants do all three, the locals value them in this order:
- Food: The most critical use.
- Medicine: A close second.
- Animal Feed: Important, but slightly less prioritized than human needs.
3. The Star Player: Icacina senegalensis
Out of 70 different useful plants they found, one stood out as a "superstar": Icacina senegalensis.
- What is it? It's a plant with a tuber (like a potato) and seeds.
- How is it used?
- As Medicine (57%): This is its main job. Locals use it to treat a long list of ailments, including yellow fever, stomach aches, muscle pain, burns, and even as a dewormer.
- As Food (43%): The tuber and seeds are eaten or turned into flour.
- As Animal Feed: It also helps feed livestock.
- The Verdict: It's a "Swiss Army Knife" plant—one tool that solves many problems.
4. The Bad News: The Pantry is Shrinking
Despite the plants being so useful, the locals have a worrying observation.
- The Current State: Most people say the vegetation is "moderately abundant." It's not empty, but it's not overflowing either.
- The Trend: The overwhelming majority (87%) say the situation is getting worse. They see fewer plants every year.
- The Star Player's Status: Even the super-useful Icacina senegalensis is becoming scarcer. It's currently "moderately abundant" but is on a downward trend.
Why is this happening?
The paper points to human activities like cutting down trees for farming, overgrazing by animals, and bushfires. It's like someone constantly taking items off the pantry shelf without restocking them.
5. The Rescue Plan: How Locals Want to Fix It
Faced with a shrinking pantry, the communities proposed a "To-Do List" to save their vegetation:
- Reforestation (42%): The top priority. Planting new trees is the most popular idea.
- Protection (17%): Guarding existing trees from being cut or burned.
- Firebreaks (10%): Creating clear zones to stop fires from spreading.
- Other ideas: Awareness campaigns, creating community reserves, and stopping people from cutting trees indiscriminately.
The Bottom Line
The study paints a picture of a community deeply connected to nature. They know exactly which plants feed them, heal them, and protect them. However, they are also sounding the alarm: the "green pantry" is running low. While they have a clear plan to fix it (mostly planting more trees and protecting what's left), the paper suggests that without help and coordinated effort, the decline might continue.
In short: The plants are the lifeblood of these communities, but the lifeblood is thinning out, and the locals are ready to fight to save it, starting with planting more trees.
