Droughts and Floods

The latest news indicates that the monsoons and the flood situation has receded in most parts of India except in the North East where Manipur valley continues to suffer from incessant rains and flooding with attempts being started at flood management.

Recent reports on the monsoon and the flood situation indicate that the rainfall has receded from northern India and has shifted to the south of India. Reports indicate heavy rainfall and flooding in parts of Maharashtra, Karnataka, Tamil Nadu and Kerala. Reports also indicate that India’s 16-week monsoon period has ended last week and the meteorological department has confirmed of 102% than normal rainfall. Inspite of the floods and the problems associated with it, reports also indicate positive news that the heavy rainfall has helped to recharge lakes and water bodies in different parts of India and may see a positive impact on agriculture in the coming days.

• The news earlier in the week still reports of flood fury in different parts of North India such as Haryana, Punjab, Uttar Pradesh, Bihar, Hyderabad, Delhi, Agra. However, in the later part of the week, the flood situation seems to be easing in most parts of the North such as Punjab, Haryana, Himachal Pradesh, Uttaranchal except in Uttar Pradesh, especially western, where the situation still continues to be grim.

Heavy monsoon rains had pushed the Ganges and other rivers over their banks by late September 2010. The flooding left at least 2 million people homeless in northern India, Reuters reported. Some 500,000 hectares (1.25 million acres) of agricultural land were also flooded. Authorities reported that the Ganges and its tributaries had risen to near record levels, and meteorologists forecast more rains in the days ahead.

Reports of floods, swelling of rivers continue from various parts of North India such as Delhi, Punjab, Haryana, Chandigarh, Bihar, Uttar Pradesh, Uttarakhand. There have been reports of landslides in the Himalayas, Himachal Pradesh, especially Shimla where the tourism industry has suffered and tourists have been reported to be stranded because of floods and landslides. Uttar Pradesh and Uttarakhand have been the worst hit with a high number of deaths due to monsoon and floods.

Flood forecast alerts are provided by Central Water Commission. They have boring maps and tables. Also they don’t provide data in program accessible format. Members of ICTD for asia are working on parsing and storing that data. In the meantime I wanted something to play. I found ScraperWiki (hacker news discussion) which can be used to scrape data from any page and schedule it for running. It allows php, python and ruby languages. Its easy and gives lot more flexibility than Y! pipes to scrape that data. Here is my scraper to get the flood data. You will have to register to get an API to use the data. Data is available in JSON, XML, PHP etc.

The Eleventh Plan (2007-08 to 2011-12) sought to build on the gains achieved in the Tenth Plan and shift the economy to a path of faster and more inclusive growth. The Mid Term Appraisal (MTA) report for the Eleventh Five Year Plan 2007-2012  by the Planning Commission reviews the experience in the first three years of the Plan and seeks to identify areas where corrective steps may be needed.

In the light of the recent major floods in river Yamuna, the enclosed article that deals with the question and futility of man made structures like dams and embankments to control floods may be found useful.

But it is unfortunate that even this otherwise very insightful article does not reflect anywhere on the fact that the floods in monsoon months are natural events and should be acknowledged and planned for accordingly.

There is a need to better understand the phenomenon of floods and not to treat them as some kind of natural calamity requiring artificial man made safeguards.

It may be noted that Dr D K Mishra who has studied the floods in river Kosi for decades has been making these points for many years now. It is necessary to heed to people like him if we do not wish to invite more trouble in future.

Floods, rains, droughts

There have been reports of flooding as well as incessant rains in the northern parts of India such as Delhi, Punjab, Haryana, Chandigarh, Uttar Pradesh, Rajasthan as well as the northeast such as Assam, Arunachal Pradesh. At the same time, reports indicate that parts of Madhya Pradesh have been facing severe drought while parts of Himachal Pradesh indicate sudden drops in temperature with reports of snowfall in certain areas. Reports from  West Bengal also indicate extensive flooding in certain parts of the state.
