Question

mining has caused serial land degradation in goa? why?

Answer 1

Goa is the smallest state of India with a population of 1,347,668 as per census 2001 and an area of 3,702 sq. km. Distance between North to South is 105 km while East to West it is hardly 50 kms. It is located in a very strategic location between Arabian sea to the West and Western Ghats to the East. Western Ghats in Goa covers an area of 700sq km. The coastal line is only 104 km in length where as the area of this coastal belt is only 83 sq km. Most of the tourists, around 25 lakh annually revolve around this area of the coast.

Geographically, Goa can be divided roughly into 3 categories, Sahyadri watershed, Middle plateau and the Final flood plains/alluvial flats. Goa's 11 talukas are divided according to these categories with Western Ghat talukas, Mid land talukas and Coastal talukas. Though the 4 coastal talukas of Bardez, Tiswadi, Mormugao and Salcett cover an area of only 24% of the total geographical area, they support 59% of Goa’s population. The 4 Midland talukas of Pernem, Bicholim, Ponda and Quepem cover 30% area with a population of 29%, where as Western Ghat talukas covers an area of 46% and are home to only 12% of Goa's population.

Answer 2

It is because mining removes the top layer ..or the top soil which is most fertile and contains all humus.....land degradation is removal of top soil and making land of no use so because mining just removes the upper top layer it causes land degradation....
