heavy rainfall, floods, waterlogging and measures to reduce suffering of the people

02/11/2017

Due to north-east mansoon there is heavy rain in Chennai city and coastal areas leading to floods, waterlogging etc causing suffering to the people. This is time for opposition parties, NGOs etc to offer constructive actionable suggestions and to avoid criticism of the government. Criticism is to be avoided as it will divert the attention and focus of the government leaders from urget action that they are required to take, to redress the suffering of the people.

In Indonesia, as had been reported in this blog earlier, most of the rain is made to fall over sea by cloud seeding over sea. The clouds moving after cloud seeding will have less or no rain to fall over the coastal cities and coastal places. However cloud seeding should be resorted to, after the water reservoirs are full so that there is no water shortage in the later period.

Poor Performance of Tamilnadu on agricultural front

15/01/2011

The per capita production of food grains (rice, wheat, coarse grains and pulses) in India is less than 200kg per year while in the world it is over300 kg. This means that India’s performance in agriculture needs to be improved vastly. In India among the various states, Tamilnadu’s performance is very poor. During 2009-10, India produced 218 million tonnes for a population of around 1180 million. The per capita production is about 185 kg per year. Tamilnadu state produced about 8.0 million tonnes for a population of about 67 million people, which works out to a per capita production of only 120kg per year.

India’s production went up from 176 million tonnes in 1990-91 to 218 million tonnes in 2009-10 which works out to about 24%increase in 20 years. This increase itself is low. But increase in Tamilnadu is very much lower at 8% from 7.4 million tonnes in 1990-91 to only 8.0 million tonnes in 2009-10.

The reasons for the slow growth in production in Tamilnadu are:

• unremunerative prices for agricultural products resulting from high cost of agricultural labour.

• insufficient water for irrigation. During rainy season, large quantity of water flows into the sea without irrigating fields, as water is released from reservoirs even though not required, for want of storage space. So the urgent need is to construct more reservoirs which could be even underground reservoirs if necessary.

• During rainy season, large quantity of water stagnates in shallow ditches. This water evaporates in 15-20 days after the rainy season. The period of stagnation is short and the depth of ditches is low and these do not permit recharge of underground water. What is required is to drain this water into nearby lakes where lakes exist nearby or to construct lakes in suitable area.

• Fertilizer use is satisfactory. In addition, there is enough manure by way of cow dung, chicken refuse, dry and green leaves etc.
