2.1 Breve descripción de la Tecnología

Definición de la Tecnología:

Use of contour ridging cultivation, tiles, manure application and improved genetic material for sustainable cassava production in convex sloppy landforms.

2.2 Descripción detallada de la Tecnología

Descripción:

Contour ridges cultivation is a seasonal water conservation and erosion control land tilling practice aiming at improving production of cassava (Manihot esculenta), improving potential of the soil and environmental function of the land. The technology is among a list of basket of choices of SLM practices recently introduced and adapted to the area by land user working in collaboration with extension officers/SLM specialists under the auspicious support of the Tras-boundary Agro-ecosystem Management Project (Kagera TAMP).
Contour ridges are cultivated in rows across a convex slope landform of average slope category lying between 5-8%. The average height of a ridge is 0.45 -0.50m, with width lying between 0.4 -0.5m, and the distance between rows is 1 meter. To be stronger, contour ridges are tied with furrows (Tiles) dug along the slope intercepting the ridges almost perpendicular. Within a cassava block farm of average size 0.5 acres, the average length of a contour ridge is approximately 30 - 35m. Within tiles, pits are dug. The distance from one pit to another is usually 5 meters. Soils from dug pit are piled on the lower side of the slope to form a supportive bund which is stabilized and made productive by planting pineapples on it. The number of pineapples (suckers) planted on each pit bund is 3-4. Tiles provide diagonal strength to the ridges, trap runoff and allow water to infiltrate and be available to the plants. Manure application is done after contour ridging by incorporating or mixing manure with soil. Manure application at a rate of 12 tons per hectare is done before cassava planting.

Purpose of the Technology: The basic tenet of this technology is to turn a poorly managed land resource that is exposed to detrimental grazing, poor agricultural practices and uncontrolled fire burning into a managed, productive agricultural land that contribute to improved agriculture production, livelihood income and ecosystems (put the triple win solution into reality).
The rural food security and income are enhanced through soil erosion control, fertility improvement, beneficial harvesting of rainfall-runoff and use of improved cassava germ-plasm (with high resilience to climatic change and diseases and no use of chemicals).

Establishment / maintenance activities and inputs: The technology is largely agronomic dominated by seasonally repeatedly activities. The dominant recurrent activities are land preparation, contour ridging cultivation, tile digging (furrow digging, pit digging, bund making and pineapple planting), manure application, cassava planting, weeding and harvesting. The inputs needed are: tools (machete, sickles, hand holes), planting materials (cassava and pineapple), manure and labour.
The average costs per hectare of this technology is 1155.48 USD. Manure application is the most cost determinant factor and accounts for 50.89% of the total costs. Average production of cassava per hectare is 7,376.32 USD. In monetary terms the average benefit to cost ratio B/C is 6.38 exemplifying viability of the technology.

Natural / human environment: Naturally the environment encompasses cropland land use type , the technology is largely agronomic, climatic zone is sub humid with 210 length of growing period, slope category is foot slopes, the dominant soil textural class is loam with a medium soil depth. On human environment the defined level of mechanization is largely hand tools, production is mixed. land ownership is largely individual not titled and there is also communally owned land.

Comentarios:

Main causes of degradation: soil management (Ignorance in fertility, nutrients and moisture improvement methods, contuor ridge ploughing along the slope), crop management (annual, perennial, tree/shrub) (Poor crop husnbandry practices (use of cassava varieties prone cassava mildew, use of incorrect crop stand)), population pressure (Continuous use of the land), poverty / wealth (Incapacity to invest effectively in sustainable land managment), governance / institutional (Poor bylaw and law reinforcement especially in disease control)
