                                   Initial problem statement.

Initial statement: Restoring ans preserving aquatic life in the river.

Present Scenario.

Recently in the month of may there have been 2 cases of fish kills .

Florida:A massive sea of dead fish is clogging Florida's waterways for miles in the latest distressing die off that is rattling scientists. Hundreds of thousands of bloated, decaying fish of nearly every kind known in the area are massed along beaches and choking tributaries and estuaries in the state's Indian River Lagoon ecosystem.  Experts believe the mass die-off is linked to a number of factors. For one, unusually heavy rains from an El Nino year are washing fertilisers and pollutants into waterways, killing the fish. In addition, warmer-than-usual winter temperatures nurtured the growth of a toxic algae bloom and brown tide that depleted the water of oxygen, which is also fatal to fish.

Bengaluru:.

Residents living in and around the lake were in for a shock as they found the fish heaped around, raising unbearable stink in the water body.  sewage from the drain flowing into the lake due to a breach in a bund had depleted oxygen levels causing the large fish kill and authorities concerned had done nothing despite complaints.The incident comes even as there is a growing concern by environmentalists over polluted lakes, exemplified by the thick froth and flames from the Yamlur lake that caused ripples in the  city last year.

Causes of fish kills

In both these cases the main causes of the kills are 

1. sewage
2. depleting oxygen
3. algae
4. heavy rains
5. fluctuating temperature
6. toxins
7. thick froth
8. pollutants
9. fertilizers and pesticides

 

These causes are interdependent on each other, i.e one problem leads to another , for example the runoffs of fertilizers and pesticides from the farm and caused by heavy rains, the amount of oxygen is depleting in the river because of the algae.

The global fish die-off is already beyond catastrophic, but the "experts" seem to have little to offer in the way of answers.

On the basis of this flowchart I have made this analytical matrix to find the exact areas i should focus on .

Analytical Matrix.

on the x-axis i have taken the problems which are man made and on the y-axis i have taken the problems which are affecting the fish kills through nature .

Conclusion.

• global warming and depleting oxygen are the main causes of fish kills.
• heavy rains play a huge role in polluting the river
• domestic pollution is also a very prominent aspect of fish kills, we can do a lot on a domestic level to prevent this.
• toxic waste from the industries plays a huge role in depleting oxygen and global warming.
• toxic algae growing in the rivers is harmful for the aquatic life.

this is the scenario of water bodies all over the world, to solve this problem , i need to focus on something more specific and to which i can get access easily, since the Mula Mutha river is close by i chose that as my working area

About mula mutha river.

Mula-Mutha River in pune (India) is one of the most vulnerable water bodies to pollution because of their role in carrying municipal and industrial wastes and run-offs from agricultural lands in their vast drainage basins. Despite of the various standards and laws made by government many industries were discharging their waste directly into the river making its quality poor day by day. The restoration of river water quality has been a major challenge to the environmental managers. Detailed research and analysis is needed to evaluate different process and mechanism involved in polluting water. The aim of the work under the title is to analyze the river by dividing it into various sampling station. The present study also identifies the critical pollutants affecting the river water quality during its course through the city. The indices have been computed for pre-monsoon, monsoon and post-monsoon season at four locations, Khadakwasla , Sangamwadi, Vithalwadi &Bund Garden. It was found that the water quality ranged from satisfactory to marginal category at Khadakwasla and fell under very poor category at all other locations. This research have a vast future scope as the rapid industrialization results in formation of toxic contaminants leading to enormous damages to environment directly putting the lives at risk. Thus, this gathered information would be handy and helpful for preventing or at-least reducing the hazardous impacts.

a lot of factors affect affect the aquatic life in mula mutha , since it is close to our college, our college directly affects it,

Analytical matrix.

Conclusion.

this matrix clearly shows that

• sewage from the hostel affects the aquatic life of the river and plays a key role in cleanliness of the river.
• another factor which affects the aquatic life of the river is the waste from PMC(pune municipal corporation)
• and domestic waste from loni village also plays a major role in polluting the river.

Stakeholder analysis.

this stakeholder analysis clearly states that , 
1.Fishermen and people who are in the food business are directly affected by the aquatic life in mula mutha 
2.The livelihood of fish sellers living nearby the river is totally dependent on the river , because of the dying fishes, their career is in danger .
3.The fish that comes from the river is sold in bulk to restaurants nearby , due to the scarcity the fish prices are increasing .
4.because of the amount of pollution in the river the fishes can barely survive in the toxic water
There is no one particular solution for this problem.

Remedies.

SOLUTIONS.

There is no one particular solution for this problem, its a step by step process which will take a lot of time , and there are more than one possible solutions for a problem .

finally, i would like to thank my faculty Prof Kuntal Dey for the help .
