  10. 10. AILA – THE NIGHTMARE
  11. 11. NATURAL RESOURCE These are the abiotic or biotic products and goods provided by nature which has economic, aesthetic or other values. The Renewable and non renewable resources of study area can be categorizes as followings: -  Forest Resource  Water Resource  Land Resource  Food Resource  Energy Resource  Mineral Resource
  12. 12. FOREST RESOURCE One type of Renewable resources Used directly and indirectly Direct use of forest products are -  Fruits: - Mango, Jackfruit, Berry, Banana etc.  Medicine: - Basak, Kalomegh, Shatomuli etc.  Fuel wood: - Many trees and shrubs.  Small timber for building huts and houses. Indirect Uses of the forest includes-  Building material and furniture for urban sector.  Medicinal products collected and processed.  Gums and resins processed into a variety of products.  Raw material for industrial products and chemicals for example: - paper, pulp, juice, soft drinks, alcohols, particle board, thread etc.
  13. 13. WATER RESOURCEIt is a Renewable resource. Industrial production Agricultural activities. Shrimp, crab and salt cultivation Drinking water in that area is really a valuable resource. Salinity in land for irrigation of saline water. Sea water intrusion problems
  14. 14. LAND RESOURCERenewable if properly maintained.  Used as construction materials.  Sundarban is the habitat of many species.  Mostly used as agricultural land (70%).  Used to grow paddy, jute, sugarcane, vegetables etc.  Some salt, shrimp and crab culture.  highly potential and cultivable lands are losing their fertility due to influence of coastal aqua culture.  Land degradation due to deforestation and tide.
  15. 15. FOOD RESOURCE Fruits provided by local trees- Mango, coconut, Jackfruit, Berry, Lichi, Guava, Banana etc. Rice is widely cultivated (20% land) mainly Aman, Aus, Boro etc. Vegetables are grown- cauliflower, Bean, Cabbage, Radish etc. Spices- Pepper, Onion, Ginger, turmeric, cassia etc. Coastal aquaculture (45% land) - Crab, Shrimp, Salt etc. Dairy and poultry products from cow, goats, hen, duck etc. Sundarban provide honey and many processed food items. Food for forest animals and fishes.
  16. 16. MINERAL AND ENERGY RESOURCEThe energy and minerals are limited in the area-  Electricity is not available in every house.  Most of the people use petroleum (Kerosene, diesel, petrol) products.  The fuel woods, leaves are widely used for cooking purpose.  Wax from Sundarban areas.  The residues from agricultural activity, cow dung are used.  The presence and extraction of mineral resource is very limited. The petroleum, coal and peat are absent in geology.  Some heavy minerals may be found in sandy deposits, not economical
  17. 17. ECOSYSTEMSBiotic and abiotic compounds of a particular area and theircorrelation. Three components- Producers: - Kadam, Barai, Coconut, Mango, Paddy, Simul, Sundari and Gewa, grasses and Palms(golpata), Phytoplanktons in aquatic body . Consumers : -  Primary consumers: - Insects, rodents, rabbit, deer, cow, buffalo, goat; Humans, small crustaceans, mollusks, etc. in the aquatic habitat.  Secondary consumers: - These are carnivores and omnivores. Examples of secondary consumers are sparrow, crow, fox, wolves, dogs, cats, snakes, Humans etc.  Tertiary consumer: - Tigers, hawk, vulture, sometimes human. Decomposers: -Mainly fungi, bacteria and earthworms.
  18. 18. ECOSYSTEMS (CONTINUED)Different interactions among components create different foodchain and web.

  39. 39. Pollutionis not intense as the industrial areas such as Dhaka, Narsingdi etc. pollutionthat occurs includes: - Air Pollution Water Pollution Land Pollutionnatural & anthropogenic activities are responsible for the generation of airpollutants. Among the air pollutants these are identified: -Dust and particulate matters from millsAutomobile emission due to fossil fuel burning.Gases produced from burning of wood, plant and biomass.secondary pollutants(The acid rain which produce H2SO4, HNO3, H2CO3 etc. )
  40. 40. Water pollutiondifferent Point source and Non-point sources pollutants are responsible forwater pollution.Water pollution results from-• Disease causing agents such as virus, bacteria, protozoa etc.( For example E. coli, Streptococcus etc. )• High BOD due to discharging organic effluents in water.• Due to acid rain and soil erosion that wash away soil nutrients and accumulate in water bodies• Use of fertilizer, pesticides in agricultural causing death of aquatic organisms.• Different dissolved salts and acidic/alkaline substances• Some toxic heavy metals (As, Hg, Pb, Cr, etc.)
  41. 41. LAND POLLUTIONLand of the area is historically very fertile.Land pollution results from- The practice of solid waste disposal over the land area The practice of over cultivation and application of chemical fertilizers and pesticides degradation of land resources many natural disasters such as cyclone, tsunami, storm surge, thunder storm etc. Loss of fertility due to change in the drainage pattern of the area
