2.1 Short description of the Technology

Definition of the Technology:

An agroforestry system which combines coffee with shade trees - including fruit, timber and leguminous species - in a systematic fashion.

2.2 Detailed description of the Technology

Description:

Shade-grown coffee is a traditional and complex agroforestry system where coffee is associated with various other species in different storeys (or ‘levels’). This provides ecologically and economically sustainable use of natural resources. Café arbolado, the example promoted by PRODAF (Programme for Agroforestry Development, see related approach: ‘Agroforestry Extension’) since 1987 is one technical option for shade-grown coffee.
While based on a traditional system the shade-grown coffee technology has a specific layout, and a reduced number of intercropped species. It comprises: (1) Coffee (Coffea arabica) planted on the contour at approximately 5,000 plants per hectare; (2) Associated trees: fruits, most commonly oranges (120 trees/ha), cedar (Cedrela odorata) or caoba (Swietenia macrophylla) for timber (60 trees/ha) and also two legumes, poró (Erythrina poeppigiana) and chalum (Inga sp.) which act as shade trees and at the same time improve the soil by fixing nitrogen (60 trees/ha). Farmers often include bananas in the system. In some cases, orange trees have partly been substituted by avocado (Persea americana), soursop (Anona muricata), and/or jocotes (Spondias purpurea). The latter two command good market prices and do not compete with labour needed for harvesting and other activities; (3) Supportive soil conservation measures on steep slopes to avoid soil erosion, predominantly strips of lemon grass (Cymbopogon citratus) on the contour, retention ditches and soil cover improvement; (4) Fertilizers: both organic and inorganic combined.

Full establishment of a shaded coffee plot can be achieved in two years - after replanting trees which fail to establish. Coffee yields a harvest after two years, but timber from associated trees can be expected after only 25 years. The trees grown in association allow more efficient cycling of nutrients (because of deep rooting and nitrogen fixation) and provide a favourable microclimate for coffee. This production system is well adapted to the local biophysical and socio-economic conditions, characterised by steep erosion-prone mountain slopes, humid climate and small to medium scale agriculture. Based on café arbolado a new, and further developed system of ‘sustainable coffee’ has evolved. This involves certification of the overall process and is attractive to the growing number of environmentally conscious consumers.

Major land use problems (compiler’s opinion): Severe deforestation, inappropriate land management practices (monocultures on steep slopes; lack of conservation measures); resulting in physical (soil erosion) and chemical (fertility decline) degradation of agricultural soils, low productivity and low yields.

6.5 Adoption of the Technology

Comments:

100% of land user families have adopted the Technology with external material support
There is a little trend towards spontaneous adoption of the Technology. There is a slight trend towards growing spontaneous adoption - after the end of the programme. However, the crisis triggered by the big drop in coffee prices has had a negative impact on adoption of the technology. Many coffee farms have been abandoned specially those located under 800-900 m a.s.l. where coffee is of a lower quality due to climatic conditions.

6.7 Strengths/ advantages/ opportunities of the Technology

Strengths/ advantages/ opportunities in the compiler’s or other key resource person’s view
Increased overall crop production and diversity: coffee, fruit, timber, legumes
Different crops harvested at different periods, gives better distribution of labour (and income) throughout the year; participation of all family members; increased food security and minimal economic risk
Improved profitability.
More efficient use of nutrients, nitrogen fixation, lower inputs of fertilizers.
Increased pest resistance, lower external inputs of biocides. Coffe plants continue to produce over 25 years due to optimal microclimate (only 15 years in conventional system without trees). Production system adapted to steep erosion prone slopes, thus a productive alternative to simple afforestation. Not labour-intensive compared with structural measures of SWC. High commercial potential of environmentally friendly produced coffee due to new market trends. Price increase for agricultural inputs has favoured a shift from conventional to shade-grown coffee, the latter being a system with a higher ratio of applied inputs/harvested yields although total production is usually lower than in modern coffee plantations.

6.8 Weaknesses/ disadvantages/ risks of the Technology and ways of overcoming them

Weaknesses/ disadvantages/ risks in the compiler’s or other key resource person’s view	How can they be overcome?
Slight decrease in production of coffee per hectare compared to the conventional pure stand	Compensate by additional benefits: wood production, fruit, etc.
Short-term negative cost-benefit ratio in the first 4–5 years: Costintensive technology in the establishment phase.	Identify fast growing species or species providing intermediate products.
Timber harvest only in the long term (after 25 years)
