1. Water Resources Management

2. Drought Management & Water Harvesting Drought: Drought is condition of water deficit sufficient to have an adverse effect on vegetation, animals and man over a sizeable area.

3. Types of drought: 1)Metrological drought 2) Hydrological drought 3) Agricultural drought 4) Socioeconomic drought

4. Cause of Drought: 1)Amount of water vapor in the atmosphere 2)Shifting of air masses 3)Cold and warm water ocean currents 4)Mountains 5)Human activities 6)Global warming

5. Effects of Drought: 1)Economic: - Loss of national economic growth - Damage to crop quality, less food production - Increase in food prices - Increased importation of flood - Insect infestation - Plant disease - Loss from dairy and livestock production - Income loss for farmers and others affected - Unemployment - Loss to recreational and tourism industry - Loss of hydroelectric power - Loss of navigability of rivers and canals

6. 2)Economic: - Increased desertification-Damage to animal species - Reduction and degradation of fish and wildlife - Lack of feed and drinking water - Disease - Increased predation - Loss of wildlife in some areas and too many in others - Increased stress to endangered species - Damage to plant species - Increased number and severity of fires

7. 3)Social: - Food shortage - Loss of human life from food shortages, heat, suicides - Mental and physical stress - Water user conflicts - Political conflicts - Social unrest - Loss of cultural sites - Reduced quality of life which leads to changes in lifestyle - Increased poverty

8. Watersheds Water Harvesting

12. 5 - Region: All drainage flowing into Arabian Sea except that Indus drainage G - Basin: Tapi 2 - Catchments: Sea Confluence to Ukai B - Sub-catchments: Main Tapi 2 - Watershed: Lower Tapi nearer its confluence to sea a – Sub watershed(3000 – 5000 ha.) 1 – Mini watershed(1000 – 3000 ha.) a – micro-watershed(500 – 1000 ha.) 5G2B2a1a (Code of Hydrology)

13. i) Fan-shaped Watersheds ii) Fern-Leaf shaped Watersheds

15. Characteristics of Watersheds based on: 1.Size 2. Shape 3. Land 4. Slope 5. Climate 6. Drainage 7. Land use 8. Vegetation 9. Geology and Soil 10. Hydrology

17. Objective of Watersheds Management 1) Conserving Soil & Water

18. GULLY PLUGGING

19. CONTOUR(SOIL)BUNDING/SOIL WITHS STONE BUNDING

20. CHECK DAM

27. Water Requirement 1) For Irrigation

30. 2) For Hydropower generation

31. 3 For Domestic Water Supply

32. 4) For Navigation requirement

33. 5) For Fish and wild life

35. 5) For Recreation -Boation -Fishing -Swimming -Sports

36. 2) Ground Water Recharge

37. 3) Growing greenery

38. 4) Rain Water Management or Roof Water harvesting System

39. 5) Reclamation of alkali Soil
