Case Study: How the Kihamba Agroforestry System on Mount Kilimanjaro Supports Climate Resilience
The Kihamba agroforestry system, a globally recognized example of climate-resilient agriculture, is practiced by the Chagga community on Mount Kilimanjaro's slopes in Tanzania.
Key Features of the Kihamba System
Multi-layered Structure: The Kihamba home garden consists of four vegetation layers:
- Uppermost: Closely spaced trees for shade, medicine, fodder, fruit, firewood, and timber.
- Second layer: Multiple banana varieties.
- Third layer: Coffee shrubs beneath bananas.
- Ground layer: Vegetables and root crops such as cassava, yams, taro, ginger, and pineapple are essential for food production.
Integrated Livestock
The Kihamba agroforestry system, a closed-loop system that combines crop and animal husbandry, maximizes land productivity and sustainability by raising livestock like cattle and chickens in harmony with diverse crops. This system uses animal manure to enrich soil, reduce chemical fertilizers, and support organic farming practices. Farmers earn income through milk, egg, and meat sales, enhancing household food security and farm productivity and resilience against climate change impacts.
Traditional Irrigation
The Kihamba system relies on water management for crop production, using traditional irrigation methods like furrows and canals to channel runoff from Kilimanjaro's montane forests into home gardens. These canals, some maintained for generations, ensure adequate water supply even during prolonged dry spells, supporting food production and the lush vegetation of Kihamba gardens. Storage ponds, or "Nduwas," hold water during scarcity. This sustainable approach supports agricultural productivity and conserves vital water resources for the region.
Biodiversity Conservation
The Kihamba gardens are known for their biodiversity, achieved through a multilayered planting structure mimicking a tropical montane forest. This diversity provides resilience against pests, diseases, and climate variability. The Kihamba system, a sustainable agriculture and biodiversity conservation model, supports wildlife and beneficial insects, contributing to ecosystem health and sustainability. It conserves both cultivated and wild species, ensuring genetic resources and ecological functions in the face of environmental change.
Community and Cultural Integration
The Kihamba, a traditional Chagga family structure, is central to family life and cultural tradition. It involves a clear division of labor, with men handling tasks like pruning coffee trees and supervising farm operations and women handling firewood, weeding, and livestock care. This structure empowers women, who are the backbone of home-based farming in Chagga society. It promotes social cohesion and gender inclusion, making it a living symbol of Chagga heritage.
Climate Resilience Outcomes
Enhanced Food Security: The year-round production of food and cash crops provides households with resilience against climate shocks and market fluctuations.
