  2. What is a wetland? Wetlands are interface between Terrestrial and aquatic ecosystems . It is an area of land whose soil is Saturated with moisture either permanently or for a long enough season every year to support aquatic plants. Wetlands are ecosystems whose formation, processes and characteristics are determined by water. Wetlands are not necessarily "wet" all year round They have been called the 'nature's kidneys' because they cleanse our environment.

  3. Facts About Wetlands Wetlands are typically low-lying areas They can be natural or man-made They can be coastal or inland Floodplains, swamps, marshes, mangroves deltas and lakes are some types of wetlands. A paddy farm is also a wetland Wetlands can contain fresh water, salt water, or brackish (a combination of the two)

  4. Ashtamudi (Wetland) • Bhitarkanika (Mangroves) • Bhoj (Wetland) • Chandertal (Wetland) • Chilika (Lake) • DeeporBeel • East Calcutta (Wetlands) • Harike (Lake) • Hokera (Wetland) • Kanjli • Keoladeo (National Park) • Kolleru (Lake) • Loktak (Lake) • Point Calimere (Wildlife and Bird Sanctuary) • PongDam (Lake) • Renuka (Lake) • Ropar • Rudrasagar (Lake) • Sambhar (Lake) • Sasthamkotta (Lake) • Surinsar – Mansar (Lakes) • Tsomoriri • Vembanad-Kol (Wetland) • Wular (Lake) • Upper Ganga River (NaroratoBrijghatstretch) Some important wetlands in India

  5. Importance of wetlands Wetlands are among the most productive ecosystems in the world, comparable to rain forests and coral reefs. They provide rich habitat for an immense variety of species of microbes, plants, insects, amphibians, reptiles, birds, fish, and mammals. Manyspecies of birds and mammals rely on wetlands for food, water, and shelter, especially during migration and breeding.

  6. Uses of wetlands water management Think of a wetland as a huge sponge Wetlands store water when it is in excess and release it to the ground during dry periods This helps in recharge and discharge of groundwater They assist in flood control They reduce the momentum of water as it flows to a river or a stream, thereby reducing soil erosion They are also important to the nutrient cycle.

  7. Uses of wetlands environmental Wetlands plants and soil store carbon instead of releasing it to the atmosphere as carbon dioxide. Thus they help moderate global climate Wetlands help retain sediments and increase soil fertility Many wetlands remove pollutants from surface runoff and small streams. Plants that grow in wetlands are very effective in filtering out water pollution Mangroves can protect shorelines from strong winds and can reduce the impact of hurricanes and tsunamis

  8. Uses of wetlands – economic Wetlands provide livelihoods by being a source of (Consumptive use ) • Agricultural produce • Craft materials • timber production • Medicinal plants • Fishing • Hunting They can also be recreation spaces (non-consumptive uses ) Wetlands provide opportunities for humans to enjoy outdoor activities, such as canoeing, fishing, and bird watching.

  9. How wetlands work Contaminants and sediments are filtered. Provides critical wildlife habitat Cleaner water outflow

  10. Threats to wetlands Natural Natural disasters like hurricanes and floods Over grazing by wildlife Drought

  11. Threats to wetlands Anthropogenic 1.Development Draining out wetlands for construction Damming them to form lakes or ponds Diverting water flow 2.Pollution 3. Sand and gravel mining 4. Global warming 5. Acid rain

  12. Ramsar convention The Convention on Wetlands -- called the "Ramsar Convention" – was signed inRamsar, Iran, in 1971. An intergovernmental treaty - embodies the commitments of its member countries to plan for the "wise use", or sustainable use, of all of the wetlands in their territories.

  13. What can we do? DO A PROJECT SHOW IT TO YOUR CLASS TALK TO THE OWNER OF A WETLAND Take an initiative, talk to the owners of a wetland on preserving them. ORGANIZE A FIELD TRIP Organize a class field trip to a wetland (preferably a destroyed one) and explain about the history of the wetland and why it was destroyed. MAKE SURE YOUR HOUSE ISN’T BUILT ON WETLAND

  14. Hi! I’m the quiz master! Click on the button with the right answer. Good luck! Quiz master

  19. Wrong!!!!!!!!! Sorry! The right answer is “A wetland is a low area where the land is filled with water.” Quiz master

  20. Correct!!!!!!!!! Woohoo! That is right! Congratulations! Quiz master

  21. What is NOT a way to help increase awareness about wetlands? Q. 3 Do a project on wetlands Organize a field trip to a wetland Play games on the computer

  30. Activities Here is an activity you can do in class Step 1 Divide your class into groups of not more than 5 people each. Step 2 Use the facts on the next page (note : some of them are false) and give each group a few facts, equal amounts of true and false. Step 3 Each group in turn says one fact. After they say it, someone from another group has to say whether the fact is true or false. If he/she is right, the team gets a point. If he/she is wrong, they lose a point. The team with the most points wins.

  31. Facts The water hyacinth is a plant A wetland is always natural The water should have a pH level between 6.5 and 8.5 Mangroves are groves of mango trees . True If the water is acidic then it is hard for animals to live Wetlands always have salty water False Wetlands provide a good habitat for animals 4.0 is a good pH level for a wetland Reeds can be found in wetlands Building a house on a wetland is good . These are just a few facts that you can use, why not try making some more?

  32. A word search on Ramsar sites in India Find the following: Ashtamudi, Bhitarkanika, Bhoj, Chilika, DeeporBeel, East Calcutta, Harike, Kanjli, Keoladeo, Kolleru, Loktak, Point Calimere, PongDam, Ropar, Sambhar, Sasthamkotta, Tsomoriri, Vembanad-Kol, Wular Can younamethestateswherethesewetlands are found?

  33. A word search on Ramsar sites in India answers

  34. Thank you! Now that you know about wetlands, take a step forward and do something! (See slide 13for ideas) Watching this slideshow will not only help you, but can help other people, animals and plants. It can help the environment, but you need to start and set the trend. Let other people know about the destruction of wetlands. MAKE A DIFFERENCE!
