CASE STUDY METHODS FOR FIELD STUDY IN ENVIRONMENT PERCEPTION
ANALYSIS & FINDINGS
• Integral part for any civilization to flourish • Act as a source of fresh water • Ground water recharge and flood control • Open space right in the midst of the settlement • Maintain the biodiversity level, the temperature and water level of a place
• Both surface and groundwater of the cities are declining. • Most of the lakes are converting into real estate, dumping yards for sewage and industrial waste. • The urban lakes, ponds, tanks and other bodies of water are getting extinct due to intensified human activities, unplanned development and lack of awareness.
• Ahmedabad lies in the north region of Gujarat, which is plain, dry and sandy area. • In such a situation natural or man-made water bodies become essential to maintain its environment. • But rapid economic development of the city has resulted into decline of its environment. rojnuamdavad.wordpress.com
• But the once inherent part of the city life, lakes have been lost in the wake of development. • The unauthorized and unchecked water withdrawal has led to the severe problems of its fast depleting ground water resource. • The graph below depicts the plight of the decreasing lakes in the city.

CONSTRUCTION OF WALKWAY OFFICE/GUARD ROOM FOUNTAIN LAWN/PLAY AREA AROUND LAKE
STAKEHOLDERS PUBLIC Residents near the lake use this lake for activities like jogging, walking, and refreshment. The visitors feel the lake here provides good air quality, and a better environment. According to them if the lake is provided with good amount of security and daily cleaning is done then it can be really advantageous.
Who get livelihood from the people visiting the lake. They use the water from the supply outlet from narmada.
There are not many vendors near the lake.
BEFORE CONSTRUCTION Lake was small Periphery wall was not constructed Due to silt formation the lake ‘s depth had decreased.
CONCEPTUAL SECTION 1998
Temporary slum dwellers around the lake Water logging in the nearby areas during rainy reasons.
AFTER CONSTRUCTION LAKE AREA WAS INCREASED SLUMS WERE COMPLETELY REMOVED SILT WAS REMOVED COMPLETELY TO INCREASE THE WATER STORAGE
CONCEPTUAL SECTION 2012
WATER LOGGING PROBLEM WAS DECREASED TO A LARGE EXTENT BOUNDARY WALLS WERE FORMED AROUND THE LAKE PAVED PATHWAY WAS CONSTRUCTED

Other Parameters :
1. THE INITIALLY SMALL LAKE WAS SAFEGUARDED FROM CONTAMINATION AND REFURBISHED INTO A BIGGER LAKE FOR STORM WATER DRAINAGE AND RECREATIONAL USES.
2. THE BEAUTIFICATION OF THE LAKE HAS ENHANCED THE ECONOMY IN THE SURROUNDING AREAS. 3. IT IS EASILY ACCESIBLE TO THE RESIDENTIAL AREAS AROUND IT AND CREATES A VIBRANT SPACE IN THE LOCALITY 4. PARKS & BENCHES PROVIDE COMFORTABLE SEATING TO CHILDREN AND AGED PEOPLE
1. PLANNING TREATS URBAN WATER BODIES AND RESOURCES MERELY ON NUMERICAL DATA, SOMETIMES IGNORING THEIR NATURAL EXISTENCE. ITS TIME TO MAKE THEM MORE AESTHETICALLY AND ENVIRONMENTALLY SOUND. 2. INTEGRATING THE WATER BODIES IN CITY PLANNING HELP TACKLING THE ISSUE OF STORM WATER AND REJUVENATING THEM WILL IMPROVE THE URBAN LANDSCAPE AND ALSO PROVIDE A PLACE FOR SOCIAL GATHERING AND RECREATIONAL PLACE.
