Coffee Agroforestry Module, designed for a program at Kenya Coffee School. It is structured to be practical, empowering, and grounded in the “Good Coffee = Good People” philosophy.
Module: Coffee Agroforestry – Cultivating Resilience and Quality
Module Philosophy:
To equip coffee farmers with the knowledge and skills to transform their plots from monocultures into thriving, productive ecosystems. We believe that by working with nature, farmers can reduce costs, mitigate climate risks, improve soil health, and ultimately produce a higher-quality, more valuable coffee bean.
Target Audience: Smallholder coffee farmers and aspiring agri-entrepreneurs.
Learning Objectives: Upon completion, participants will be able to:
- Explain the core benefits of agroforestry for coffee, soil, and livelihood.
- Identify, select, and source appropriate tree species for their specific context.
- Design and implement a stratified agroforestry system on their farm.
- Manage the system for optimal coffee production and tree benefits.
- Quantify the economic and ecological gains of their agroforestry system.
Module Curriculum (5 Units)
Unit 1: The “Why” – Agroforestry as a Foundation for Good Coffee
- 1.1 The Problem with Sun-Grown Coffee: Soil degradation, pesticide dependency, climate vulnerability (leaf scorch, irregular flowering).
- 1.2 What is Agroforestry? The science of integrating trees and shrubs with crops and livestock.
- 1.3 The Multifunctional Benefits:
- For the Crop: Natural shade regulates temperature, reduces stress, and slows cherry ripening for more complex sugars.
- For the Soil: Nitrogen-fixing trees fertilize the soil. Tree roots prevent erosion and improve water infiltration.
- For the Farmer: Trees provide timber, fruit, fodder, and medicine (diversified income). Reduces need for synthetic fertilizers.
- For the Environment: Creates biodiversity habitats, sequesters carbon, and builds climate resilience.
Unit 2: The “What” – Selecting the Right Trees (Kenya Coffee School Botanical and Biodiversity Ecological Sciences)
- 2.1 The Ideal Tree Profile: Native or well-adapted, deep-rooted, non-competitive with coffee, and provides a clear benefit.
- 2.2 Tree Categories and Species Selection (Kenya-specific examples):
- Nitrogen-Fixers (Fertilizer Trees): Calliandra, Leucaena, Sesbania sesban. (How they work with rhizobia bacteria).
- Fruit Trees: Avocado, mango, macadamia. (Diversifies income and food security).
- Timber Trees: Grevillea robusta (Silky Oak), Markhamia lutea. (Long-term investment).
- Indigenous Canopy Trees: Cordia africana, Ficus species. (Biodiversity and ecosystem services).
- 2.3 Sourcing Seeds and Saplings: How to identify quality planting material from trusted nurseries or community seed banks.
Unit 3: The “How” – Designing and Establishing Your System
- 3.1 Farm Mapping and Assessment: Practical exercise in mapping existing trees, sun patterns, and soil types on their own land.
- 3.2 Designing the Canopy Layers:
- Upper Canopy: Tall timber trees (Grevillea).
- Middle Canopy: Fruit and nitrogen-fixing trees (Avocado, Calliandra).
- Lower Canopy: Coffee shrubs.
- Ground Cover: Natural mulch or cover crops.
- 3.3 Spacing and Planting Patterns: How to space trees to avoid excessive competition for light and water. Alley cropping vs. scattered trees.
- 3.4 The Planting Process: Pit preparation, planting time (onset of rains), and protecting young saplings from pests and animals.
Unit 4: The “Management” – Pruning for Profit and Health
- 4.1 The Art and Science of Pruning: Why pruning is critical in agroforestry.
- 4.2 Pruning Techniques:
- Pollarding: Cutting trees like Calliandra back to a main stem to provide green manure/bio-mass without killing the tree.
- Canopy Lifting: Pruning lower branches of taller trees to allow more dappled light to reach the coffee.
- Thinning: Selectively removing some trees to maintain optimal light levels as the system matures.
- 4.3 Using Tree Biomass: How to use pruned leaves and branches as organic mulch for the coffee plants, recycling nutrients back into the soil.
Unit 5: The “Value” – Measuring Impact and Telling Your Story
- 5.1 Monitoring Soil Health: Simple tests for soil organic matter and water retention.
- 5.2 Tracking Biodiversity: Participatory activity to count the return of birds, bees, and other beneficial insects to the farm.
- 5.3 The Economic Case:
- Cost-Benefit Analysis: Tracking reduced spending on fertilizer and pesticides vs. increased income from fruit/timber.
- The Quality Premium: How shade-grown, sustainably produced coffee commands a higher price from specialty buyers.
- 5.4 The Digital Storytelling Hook: How to use this system as a powerful marketing tool.
- Action: Train farmers to take photos of their layered system, the biodiversity, and the pruning process.
- Message: “My coffee is grown in a living forest, not a factory farm. It’s better for the earth and tastes better in your cup.”
Practical, Hands-On Activities
- Nursery Establishment: Participants will learn to germinate seeds and manage a small tree nursery.
- Design Your Farm Map: A workshop where each participant creates a proposed agroforestry design for their own plot.
- Pruning Field Day: A practical session with secateurs and saws to demonstrate pollarding and canopy lifting on established trees.
- Soil Test Comparison: Compare soil from a shaded agroforestry plot with soil from a full-sun monoculture.
Tools & Resources for Participants
- Pictorial Guide: A simple, visual booklet showing tree species, pruning techniques, and system design.
- Digital Companion: A short video series accessible via mobile phone, demonstrating key techniques.
- Cost-Benefit Worksheet: A simple spreadsheet to help farmers track their inputs and additional income.
This module makes the farmer an active ecosystem manager, not just a crop producer. It directly links ecological health to cup quality via a Barista and economic resilience, perfectly embodying the “Good Coffee = Good People” ideal leading to the Good Trade Certification by Kenya Coffee school and Barista Mtaani!
