DEGRADATION OF THE RIVERINE ECOSYSTEM OF NAIKA RIVER

  1. 1. DEGRADATION OF THE RIVERINE ECOSYSTEM OF NAIKA RIVER Ryan Daimari & Paran Swargiary Guide Teacher: Dhrubajyoti Sarmah Arunodoi Academy, Tangla Class 9
  2. 2. INTRODUCTION The river is the rudimentary lifeline of the ecosystem and ultimately the important facet of the prominent life forms of the land lock vicinities. Many successful civilizations took place nearby the rivers like Nile. In the modern days too, cities like London also flourished on the bank of river Thames. A river has the potential to bring life with it and also create a whole new ecosystem at its will. So, it becomes our obligation to care of the rivers. Unfortunately, many of the contemporary urban places are evolving to make major perils to the rivers and its riverine ecosystem. The river Naika, passing through Tangla is currently suffering from the ominous consequences of on going human activities in Tangla and its surrounding areas.
  3. 3. OBJECTIVE: To find out the solution for improvising the ailment of the of Naika river with reference to the biodiversity of the riverine ecosystem. To up rise a balance between the urban development and the riverine ecosystem of Naika. To encourage the people to come up with ideas, techniques and suggestions to diminish waste disposal in Naika river.
  4. 4. The Nuisances  With the continuous rise of population the need for resources also have increased considerably. As a result, the production of waste has gone up to a large extent. This has made it necessary to improvise and upgrade the waste management system to get rid from this serious issue.  During monsoon, the river Naika is observed to be high on current and its water level rises to about 8 feet flooding the adjacent streets and residential areas. This causes the waste materials on its bank to flush away making the river dirty.  Flooding on the banks of the river causes erosion of soil and subsequently the river bed is rising silently.  Due to the poor water quality, the local people who could earlier utilize the water from this river for their daily uses, are now afraid of using the water as they reported to suffer from itching and other skin infection in contact with this water.
  5. 5. Atrocities  Throwing waste materials into the river has divested the water quality of the river.  Faults and negligence of the drainage system from the residential areas outlets all the wastes from homes directly into the river.  The jeopardized construction of bridges and other infrastructures along the river side has led to mix huge amount of sand, cement and other construction materials to the river water.
  6. 6. Sewage, garbage and waste from households, shops etc. are dumped into rivers at very large scale. These wastes contain many chemicals and poisonous substances which are very harmful to plants and animals dependent on the river water and living in it.

  8. 8. CHARACTERISTICS OF NAIKA RIVER  The river originates from Kachubil Tea Esate near Paneri  The river flows through Paneri, Sastrapara, Jalukbari, Tangla and Tokankata covering a distance of approximately 16 kms.  At Tokankata river Naika recieves a tributary “Hurduma” (slightly smaller in size than Naika) and finally flows to fall in to river Nonai, which is roughly fouir times larger in size than Naika.  After that they move together towards south up to Mangladoi and fall in to mighty Brahmaputra.

  10. 10. REMEDIAL MEASURERS  Digging down silt settled at the river bed.  Installing proper waste disposal system all across the residential areas near the river bank.  Setting up guard walls along the river laterals.  Improvisation and upgradation of the faulty drainage system.
  11. 11. OUTCOMES  Minimization of river bank erosion of Naika river is a prime need.  Protection of the surrounding residential area of the river Naika from calamities like flood is necessary.  To protect the riverine ecosystem that presides in the Naika river.  To improve the water quality so that it becomes suitable for human use.  To keep the biodiversity of the river ecosystem in a manner so that the aquatic life forms can survive in the river.
