Comparative Study of Soil Samples from Gottigere Lake and Madiwala Lake

Slide Note

This study compares the soil samples from Gottigere Lake and Madiwala Lake in Bangalore, India, analyzing macronutrients, micronutrients, and indicator species to assess pollution levels. The research aims to contribute to wetland conservation and ecosystem-based climate change adaptation.

Introduction LAKE 2022: CONSERVATION OF WETLANDS: ECOSYSTEM-BASED ADAPTATION OF CLIMATE CHANGE, DECEMBER 28-30, 2022 2

Analyzing the soil sample from Gottigere lake and Madiwala lake. Qualitative and quantitative analysis of macronutrients and micronutrients. To find out indicator species related to pollution.

Materials and Methods LAKE 2022: CONSERVATION OF WETLANDS: ECOSYSTEM-BASED ADAPTATION OF CLIMATE CHANGE, DECEMBER 28-30, 2022 4

Gottigere Lake Gottigere lake, with a water spread area of about 14.98 ha, is located in the Bellandur Lake catchment of the South Pennar River basin. LAKE 2022: CONSERVATION OF WETLANDS: ECOSYSTEM-BASED ADAPTATION OF CLIMATE CHANGE, DECEMBER 28-30, 2022 5

Madiwala Lake Madiwala lake is one of the biggest lakes in Bangalore, India spread over an area of 114.3 ha. Legend has it that the lake was built by the Cholas in a day. The water in the lake was fit for drinking till the early 1990s. LAKE 2022: CONSERVATION OF WETLANDS: ECOSYSTEM-BASED ADAPTATION OF CLIMATE CHANGE, DECEMBER 28-30, 2022 6

Sieve Analysis Collect 2kgs of soil from each lake. Keep the samples for overnight drying in the Hot Air Oven. Take the dried samples, and put them in the machine for sieving. Use different sizes of sieve to check the layers of soil present. LAKE 2022: CONSERVATION OF WETLANDS: ECOSYSTEM-BASED ADAPTATION OF CLIMATE CHANGE, DECEMBER 28-30, 2022 18
