2.1 Short description of the Technology

Definition of the Technology:

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

2.2 Detailed description of the Technology

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.

2.6 Date of implementation

If precise year is not known, indicate approximate date:

• less than 10 years ago (recently)

2.7 Introduction of the Technology

Specify how the Technology was introduced:

• through projects/ external interventions

Comments (type of project, etc.):

Bangladesh Agricultural Research Institute (BARI)

3.1 Main purpose(s) of the Technology

• improve production

3.2 Current land use type(s) where the Technology is applied

Land use mixed within the same land unit:

Yes

Specify mixed land use (crops/ grazing/ trees):

• Agroforestry

Cropland

• Perennial (non-woody) cropping
• Tree and shrub cropping

Perennial (non-woody) cropping - Specify crops:

• pineapple

Tree and shrub cropping - Specify crops:

• fruits, other

Number of growing seasons per year:

• 3

Specify:

Longest growing period in days: 290; Longest growing period from month to month: Jun - Aug

Forest/ woodlands

• Tree plantation, afforestation

Type of tree:

• Bamboo bamboo

Products and services:

• Timber
• Fruits and nuts

Waterways, waterbodies, wetlands

• Ponds, dams

Main products/ services:

Fishes in aquaculture

Comments:

Major land use problems (compiler’s opinion): Poor secondary forest where bamboo and small timber species were harvested that accelarate land degraded.

Major land use problems (land users’ perception): Poor return from jhum.

Type of cropping system and major crops comments: Pine apple can harvest first then fruits in second, them timber and again fruits and timber

3.4 Water supply

Water supply for the land on which the Technology is applied:

• rainfed

3.5 SLM group to which the Technology belongs

• agroforestry

3.7 Main types of land degradation addressed by the Technology

soil erosion by water

• Wt: loss of topsoil/ surface erosion

Comments:

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)

4.1 Technical drawing of the Technology

4.2 General information regarding the calculation of inputs and costs

other/ national currency (specify):

Taka

If relevant, indicate exchange rate from USD to local currency (e.g. 1 USD = 79.9 Brazilian Real): 1 USD =:

60.0

4.3 Establishment activities

4.4 Costs and inputs needed for establishment

Comments:

Duration of establishment phase: 0 month(s)

4.5 Maintenance/ recurrent activities

5.1 Climate

5.2 Topography

Comments and further specifications on topography:

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 Soils

If available, attach full soil description or specify the available information, e.g. soil type, soil PH/ acidity, Cation Exchange Capacity, nitrogen, salinity 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.

5.6 Characteristics of land users applying the Technology

Indicate other relevant characteristics of the land users:

Population density: < 10 persons/km2

Annual population growth: 2% - 3%

and own 20% of the land (Few family purchase lands after getting normal lease amount and they have acces to othr busines or i).
and own 80% of the land (They donot have other options for more income.).

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.
