CLASSIFICATION OF ALTERNATE LAND USE SYSTEM

In this presentation you will come to know about the CLASSIFICATION OF ALTERNATE LAND USE SYSTEM. That is:
DEFINITION OF ALTERNATE LAND USE SYSTEM
DIFFERENT CLASSIFICATIONS BASED ON IT.
And also you will come to know about the use of alternate land use system in different aspects in agricultural sector.

1. AGR - 302 - RAINFED AGRICULTURE AND WATERSHED MANAGEMENT (1+1)

2. Classification of alternate land use systems

3. ALTERNATE LAND USE SYSTEMS It is defined as an effective economic  utilization  of  land  without harming the natural resource structure based on  land capability .  Land use systems  which are  alternatives  to crop production. Same  lands  may be suitable for range/pasture  management  and for tree farming and ley farming, dryland horticulture and agro -forestry  systems  including alley cropping. All these  systems  which are  alternative  to crop production are called as  alternate land use systems .

4. CLASSIFICATION OF ALTERNATE LAND USE SYSTEMS The alternate land use systems is classified based on the following factors: Classification based on structural systems, Classification based on importance, Classification based on the dominance of the components, Classification based on the temporal arrangements of the components, and Classification based on allied components.

5. Classification based on structural SYSTEMS It can be defined in terms of its components (constituents) and the expected role (functions) of each of the components that is important that is important but also their arrangements. In agroforestry land use system, there are 3 basic sets of elements or components that are managed by mam. They are: Tree Herbs (agricultural crops including pasture crops) and animals

6. Following systems are available based on structural classification : Agri- silvi -system (crops and trees including shrubs/vines) Silvi pastoral system ( pastures/animals and trees) Agri- silvi -pastoral system (crops, pastures/animals/trees) Agri- horti system (crops and fruit spices) Silvi- horti - pastoral systems (Trees fruit crops and pastures).

7. 1) AGRI - SILVI SYSTEM Agri silviculture is production scheme that supplies wood stuffs and/or animal products from a single management unit where good agricultural practices Agri-silviculture systems are combinations of crops and trees, such as alley cropping or home gardens.

8. 2) SILVI - PASTORAL SYSTEM The productivity of woody plants combined with pasture is referred to as a SILVI-PASTORAL SYSTEM. The trees and shrubs may be used primarily to produced fodder for livestock or they may be grown for timber, fuelwood, and fruit or to improve the soil. A silvi -pastoral system is needed in dry areas, in order to meet out the demands of wood and fodder throughout year.

9. There are 3 main categories of silvicultural systems & they are as follows: Protein bank Live fence of fodder trees and hedges Trees and shrubs on pasture land

10. Protein bank In this system, various multipurpose trees (protein rich trees) are planted on or around farmlands and rangelands. For cut and carry fodder production to meet the fodder requirements of livestock's during the fodder deficit period in winter. These trees are rich in protein. The trees planted in PROTEIN BANK ARE: Grewia optiva , Bauhinia variegate , Morus alba , Artocarpus spp., Anogeissus latifolia , Cordia dichotoma , Dolbergia sissoo , etc.,

11. B) LIVE FENCE OF FODDER TREES AND HEDGES In this system, various fodder trees and shrubs are planted as live fence to protect the property from stray animals. To protect the farm property from biotic influences. The following trees are generally used: Sesbania grandiflora , Gliricidia sepium , Euphorbia spp, Acacia spp. Etc.

12. c) Trees and shrubs on pasture land : In this system various trees and shrubs species are scattered irregularly or arranged according to some systematic pattern.

13. 3) AGRI - SILVI - PASTORAL SYSTEM Growing of trees, agricultural crops and grasses together in same lands at the same time is known as AGRI-SILVI PASTORAL SYSTEM. This is typically hill farming system of Nepal, in which agriculture crops are grown in terrace flats, trees in terrace bunds, borders and slopes and grasses in terrace slopes, and some farmers have been growing improved legume and non-legume grasses such as MOTT NAPIER ( Pennisetum purpureum ), Setaria ( Setaria splendida ),

14. 4) AGRI - HORTI SYSTEM This system is defined as growing of agricultural crops, trees and fruit trees or ornamental trees or vegetables/flower together in same lands at the same time. The tree crops such as Tankii, Ipil ipil etc. and timber and firewood species such as Sissoo, Eucalyptus, etc.,. Are grown around fruit orchards that acts as an shelter belt, and agricultural crops such as ginger, turmeric, yam, colocassia and vegetables are grown under fruit trees.

15. 5) SILVI - HORTI PASTORAL SYSTEM Growing of fruits crops or growing of horticultural crops on an pastoral land is called as SILVI-HORTI PASTORAL SYSTEM.

16. B) CLASSIFICATION BASED ON IMPORTANCE The agro-foresty system could also be classified on the basis of importance given to a constituent viz., based on the main structure. Example: agri-silvi , agri-horti , horti , silvi , silvi pastoral etc.

17. C) CLASSIFICATION BASED ON DOMINANCE This system could be defined on the basis of dominance of the components.

18. D) CLASSIFICATION BASED ON TEMPORAL ARRANGEMENTS OF THE COMPONENTS It includes the following: COINCIDENT: different crops occupy the land together e.g., coffee under shade trees, pasture under trees. CONCOMITANT: The component stay together for some part of the life. E.g , agricultural crops are grown for only a few years. INTERMITTENT: Space is dominated, the annual crops are grown with perennial crops. INTERPOLATED: Space & time are dominant. Different- components occupy the space during different time as in home gardens.

19. E) CLASSIFICATION BASED ON ALLIED COMPONENT It includes the following: Agroforestry cum sericulture, Agroforestry cum apiculture, Agroforestry cum pisciculture, and Agroforestry cum lac culture
