    Preparation of Indicative Land use Plans using GIS

    3.3. Conclusion
    Misuse of land in many parts of the country has led to soil loses, lowering of productivity and decline in the natural eco-system diversity etc. It is very necessary therefore that measures be adopted to make the best use of the available land resources on a sustainable basis. Such sustainable use of course will depend on the preparation and availability of land use plans at the district and divisional level to guide the decisions of both policy makers and users of land. Such plans however cannot be prepared manually because they are needed urgently. The procedure outlined above enables the preparation of ILUP s quickly and more accurately. It also makes updating of the plans much easier as more detail permits easy retrieval of specific data as and when required by policy makers, planners and land users.

    Appendix 2
    Indicative Land Use Plan
    A. Intensively Used Land
    Land Use Categories
    Paddy, both irrigated and rained; tea, seedling and VP: rubber inter-cropped; coconut, inter-cropped and mixed with livestock; in case plantation corps such as cinnamon, cocoa, cofee, cashew, citrus, mango lemongrass, banana, sugarcane, pineapple, etc., can be marked as already intensively used; if the crop cover if more than 75% forest, dense forest and forest plantations; grassland improved and natural; garden, hoem garden and market garden; built-up areas.
    A1 Area where present land use could continue with appropriate management to maintain the land cover SLOPE(0-30%)
    A2 Area with should be used with conservation measure (seasonal corps are recommended only upto 40% (30-60%)
    A3 Area recommended for forestry. Tree crops can be permitted only if strict conservation measure are adopted. (>60%)
     
    B. Semi - Intensively Areas
    Land Use Categories
    Rubber, mono - cropped; coconut, mono-cropped; other plantation crops such as cinnamon, cocoa, coffee, cashew, citrus, mango, lemongras, banana, sugarcane, pinapple etc., if the cropcover is less than 75%.
    B1 Area where land use can be intensified with minimal restrictions. (0-8%)
    B2 Area where land use can be intensified with conservation practices. (8-16%)
    B3 Areas where land use may be intensified with careful conservation in adopting suitable conservation practices (16-30%)
    B4. Area where land use can be intensified with very strict adherence to conservation practices and good management (suitable for annual crops only upto 40%) (30-60%)
    B5. Area recommended for forestry. (>60%)
     
    C. Sparsely used Areas (Wet and Intermediate Zones Only)
    Land Use Categories
    Paddy abandoned, tea abandoned rubber abandoned, scrub /chena, natural grassland, rockoutcropps, distorted surface and barren land.
    C1 Area where can be utilized for crop production, if the constrains could be rmoved economically and suitable conservation practices are adopted; can be used for on agricultural uses as well (0-16%)
    C2 Area suitable for agro-forestry and tree crops with conservation (16-30%)
    C3 Areas suitable for agro-forestry and tree crops with conversation (30-60%)
    C4. Suitable for forestry (30-60%)
    C5. Rockout crops and distorted surfaces falling under sparsely used category may be suitable for natural forest or extraction of gravel or for quarrying ( >60%)
     
    D. Conservation Areas
    Land use categories
    Reservations, archaeological, forest, reserves, wildlife, parks &n sancturaries marsh/swamp, mangroves water bodies, and sand.
