Causes

Apart from increased downpour in the state,  many different reasons have been reported regionally. The capital of the state, Bengaluru is known to have more rainfall on an average, but in the last decade flood instances have cropped up time and again, it is attributed to amplified urbanisation causing stress on the natural resources, encroachment of flood plains, loss of vegetation and biodiversity, improper city planning leading to reckless constructions of sites and buildings. Along with these reasons, change in the river course of movement, deforestation and land modifications to accommodate tourists have been  the reasons for recurring floods and landslides in Malenadu region of the state. In northern Karnataka, heavy discharge of water from the Dams in Maharashtra and Karnataka, also aggravated the situation. Release of water from Ujjani Dam built on the river Bhima in Maharashtra rooted for flooding of 400 villages in Vijaypura, Kalburgi and Yadgir district. The Ghataprabha, Malaprabha, Tungabhadra, Almatti and Narayanapura, reservoirs were filled to the brim affecting Yadgir, Raichur, Ballari, Bidar, Vijayapura, Bagalkot, Belagavi, Dakshina Kannada, Udupi, Uttara Kannada, Gadag, Koppal, Haveri and Dharwad districts in north Karnataka.

Humanitarian response

The Karnataka Civil Administration called for a humanitarian response towards the destruction caused due to the floods. Twenty flood relief and ten Engineering Task force from Madras Engineering Group, Maratha Light Infantry Centre and Bison Division from Hyderabad were also employed to provide assistance in Yadgir, Gadag districts. More than two thousand crore rupees from State Relief Natural Disaster Fund was demanded for rebuilding houses, reestablishment of the lost livestock and creation of jobs. There was also a demand for extension of work days under the Mahatma Gandhi National Rural Employment Generation Scheme by the state government in the light of fractured employment system due to the spread of COVID19 and loss of agrarian activities in floods.
