No

2.1 Short description of the Technology

Definition of the Technology:

The plantation of mulberry plants which are allowed to grow for the production of nutrients leaves for silkworm mulberry cultivation for silkworm.

2.2 Detailed description of the Technology

Description:

After the plantation of mulberry plants. They are ready to be eaten by silkworm. Firstly, silkworm eggs must be stay between 25 to 31 "C in tray or petric dish. In this area silkworm are brought from silkworm industry of khopasi. The larvae must be transfer to clean tray with freash food. A time came in larval stage when larvae eats huge amount of mulberry and grow more than 5cm long. After enough eating, larvae raise their heads as it shows sign for cocoon formation. Then, the worm is kept in another circular bamboo which will make cocoon more uniform in slope and easier to collect silkworm by contracting secrets from an opening under its mouth a steady stream of liquid silk coated with sericine which darkens on exposure. It takes 25 days to form cocon.

Purpose of the Technology: The main purpose of planting mulberry plant is for producing silkworm to increases economic condition of farmer.

Establishment / maintenance activities and inputs: For over two years people have been implementing these technology.They took training from the khopasi silkworm institution.They have get external inputs.While getting training,maintenance has been carried out when the plants are not grown enough.While producing the silkworm (larva to cocoon) maintenance is carried out as keeping them in clean environment without reaching another species around them.

Natural / human environment: The natural environment is tropical with temperature ranging from 20 to 25°C .The population density is sparse with the community relying heavily on agriculture.

2.6 Date of implementation

If precise year is not known, indicate approximate date:

• more than 50 years ago (traditional)

2.7 Introduction of the Technology

Specify how the Technology was introduced:

• as part of a traditional system (> 50 years)

3.1 Main purpose(s) of the Technology

• create beneficial economic impact

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

Cropland

• Annual cropping
• Perennial (non-woody) cropping

Annual cropping - Specify crops:

• cereals - maize
• vegetables - leafy vegetables (salads, cabbage, spinach, other)

• wheat, tomatoes

Number of growing seasons per year:

• 2

Specify:

Longest growing period in days: 35; Longest growing period from month to month: baisakh(1-30) and bhadra(1-30)

Forest/ woodlands

• (Semi-)natural forests/ woodlands
• Tree plantation, afforestation

(Semi-)natural forests/ woodlands: Specify management type:

• Shifting cultivation

Comments:

Major land use problems (compiler’s opinion): It decreases the number of crops in surrounding and it also kills the insect afte the formation of cocoon so in certain amount affects the environment.

Major land use problems (land users’ perception): Reduce the cropping land

Cut-and-carry/ zero grazing: Yes
Plantation forestry: Yes
Constraints of infrastructure network (roads, railways, pipe lines, power lines)

3.4 Water supply

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

• mixed rainfed-irrigated

3.5 SLM group to which the Technology belongs

• beekeeping, aquaculture, poultry, rabbit farming, silkworm farming, etc.

3.6 SLM measures comprising the Technology

vegetative measures

• V1: Tree and shrub cover

3.7 Main types of land degradation addressed by the Technology

biological degradation

• Bc: reduction of vegetation cover

Comments:

Main causes of degradation: soil management, crop management (annual, perennial, tree/shrub), deforestation / removal of natural vegetation (incl. forest fires), over-exploitation of vegetation for domestic use, industrial activities and mining, urbanisation and infrastructure development, over abstraction / excessive withdrawal of water (for irrigation, industry, etc.), change of seasonal rainfall, Heavy / extreme rainfall (intensity/amounts), wind storms / dust storms, floods, droughts, population pressure, inputs and infrastructure: (roads, markets, distribution of water points, other, …)

Secondary causes of degradation: overgrazing, discharges (point contamination of water), release of airborne pollutants (urban/industry…), disturbance of water cycle (infiltration / runoff), change in temperature, other natural causes (avalanches, volcanic eruptions, mud flows, highly susceptible natural resources, extreme topography, etc.) specify, land tenure, poverty / wealth, labour availability, education, access to knowledge and support services, war and conflicts, governance / institutional
