2.1 Courte description de la Technologie

Définition de la Technologie:

Mixed fruits gardening on hill slope with forest trees on hill top and bamboo at the lower part of the hill.

2.2 Description détaillée de la Technologie

Description:

On upper part of the slope natural forest tree species were allowed to grow and lower part with bamboo. On the middle part, pineapple was cultivated along the contour as short term cash earning crop and long term fruit trees were planted for long term return within the space (alley) between two rows of pineapple. Generally farmers are acquainted to cultivate pineapple along the slope as cash earning crops and they occasionally incorporate fruit trees in the system. The technology " Hill agroforestry" describe a change in farming system where pineapple and fruit trees are grown along the contour.

Purpose of the Technology: Parmenent farming with short and long-term income generation for better livelihood as well as soil consevation.

Establishment / maintenance activities and inputs: Slash and burn (Jhum) at initial stage followed by pineapple and fruit trees along the contour to establsh a parmenent farming. Three times weedding, accumulaion of weeded material as mulch and using chemical fertilizer (urea, TSP, MP) on Pineapple on rows and individual fruit trees.

Natural / human environment: Steep slope, acidic soil, secondary vegetation, chakma community, poor, subsistance livellihood, adoption of new technology.

Pineapple cultivation on variable degrees of hill slopes along the contour with different types of fruit trees in alley and secondary forest on the top where bamboo at the lower part of the slope as well as in the upper parts of the valley.

3.7 Principaux types de dégradation des terres traités par la Technologie

Commentaires:

Main causes of degradation: over-exploitation of vegetation for domestic use (No off-farm work leads to overexploitation of forest), lack of captial (Only male are illigible to get loan from Bank), lack of knowledge (Lack of technical Know-how)

Secondary causes of degradation: deforestation / removal of natural vegetation (incl. forest fires) (If no work available peoples harvest forest product not considering carrying capasity leads to deforestation.), labour availability (Labor shortage in peek period)

4.2 Spécification/ explications techniques du dessin technique

Technical knowledge required for field staff / advisors: high

Technical knowledge required for land users: moderate

Main technical functions: control of dispersed runoff: retain / trap

Secondary technical functions: reduction of slope angle, reduction of slope length, increase in organic matter, increase of infiltration, increase / maintain water stored in soil

Fruit trees / shrubs species: Jack fruit, mango, jam, Goava,Suppery,Olive, Banana, pine apple

Slope (which determines the spacing indicated above): 50.00%

Gradient along the rows / strips: 5.00%

5.1 Climat

5.2 Topographie

Commentaires et précisions supplémentaires sur la topographie:

Landforms: Footslopes: The area is mostly in Dupitila formation where hill tops are rounded or flat resembling almost like plateau. The area is in general closely disected with V- shaped valley. Hill agroforestry is practiced on the slope and upper part of the valley. Most cases valley floors are used for paddy cultivation.

Slopes on average: Cultivation practices on variable slopes. Therefore it is difficult to define the slope class on which the technology strictly practiced.

5.3 Sols

Si disponible, joignez une description complète du sol ou précisez les informations disponibles, par ex., type de sol, pH/ acidité du sol, capacité d'échange cationique, azote, salinité, etc.

Soil depth on average: Soils on slope are shallow in general and also compact. Soils on the hill top and/or at foot slope are moderatly deep.

Soil texture: Soil texture also varies with position on the slope.

Soil fertility is very low. Soils on steep to vey steep slope has very low OM and most of the fertile topsoils are already eroded. But soil around the homsteads is more fertile (medium) because of incorporation of houshold wast. But soil around the homsteads is more fertile because of incorporation of houshold wast.

Topsoil organic matter: But soil around the homsteads is more fertile because of incorporation of houshold wast. Low as non- accumulation of OM.

Soil drainage / infiltration is good and well drained in hilly part. Valleys or upper part of the valley are of poorer drainage area.

Soil water storage capacity is high in deep or moderatly deep soil. Medium in shallow to very shallow soil.

Off-farm income specification: Only one farmer was employed

Level of mechanization: Sometimes they share within theselves to over come labor crisis. The labor and the work is suppervised by the female member of the family as the male is employed else where.
