#Elections are supposed to be about electing representations for framing legislations

However the geography behind delimitation which doesnt consider complex socio-economic conditions promote communal polarization leading to deterioration of Democractic values

1/n
Understanding Delmitation:

The constituency delimitation is based on population. and for last delineation exercise, 2001 population was used. Average population was calculated to be 270000 people per constituency

#Map shows Population spread in Tamil Nadu
2/n
To delineate which village/town comes under which constituency, some rules are followed

To achieve the avg population, officials start with headquarters for the constituencies in district & add villages/towns within same or neighbouring taluks(subdistricts) in same district

3/n
Pudukottai district has villages which are not contiguous with main district. This is a relic of British era. In this case, all such villages were added to constituencies of neighbouring district. But in other cases such crossing of district boundaries were not allowed
4/n
This doesnt mean that they haven't created islands during delineation process. For some reason, Thiruvithamcode rev.village has been added to Padmanabapuram constituency thus dividing Colachel const into 2 pieces

Thiruvathamcode gives its name to Travancore kingdom (FYI)
5/n
More the mismatch between Subdist population & avg population, the constituency boundaries become wierder

If you notice the case below from erstwhile #Coimbatore district, villages closer to other constituencies have been added to another constituency & thus HQs are at edges
6/n
Because of this indiscriminate addition from neighbouring subdistricts, #Srirangam constituency (whose HQ is north of Trichy) is extreme in all 4 cardinal directions i.e Srirangam is more northern, more eastern, more western, & more southern than both Trichy constituencies!

7/n
It means two villages which are a hundred kilometers apart geographically, socially, and economically unrelated to each other are expected to elect the same common representative.
8/n
In the case of Tengumarahada, a village in #nilgiris district, Citizens have to travel through two other constituencies -BhavaniSagar and Mettupalayam (and their HQs) for a minimum of 4 hours inorder to reach it's own constituency HQ (Coonoor)
Refer Map below

9/n
Many such cases exist for example Elandaikuttapatty and few villages around it have been added to Harur constituency instead of #Pappireddipatti a geographically closer &easily accessible town.

10/n
The problem with such selections is that smaller communities which dont have same problems as the larger constituencies get isolated, forgotten & they dont get represented in the mainstream politics while framing legislations which affect them

Map: Bodhamalai in #Rasipuram
11/n
The only time you would hear about Bodhamalai is when news breaks that EVMs have to be carried through the forest etc.
12/n

deccanchronicle.com/nation/current…
Take case of #Manjolai &neighbouring villages - part of Bombay Burma Trading Corporation's (BBTC) tea estate. BBTC's lease is about to expire in 2028 (99 year lease). Tea estate workers dont own any land which means post lease expiry, people would lose livelihood & homes

13/n
These villages have been added into #Manimuthar Town P & Ambasamudram constituency. Since their population is low they dont get represented as the rest of the constituency need not worry about this & currently there is no law or guideline to help Manjolai with transition
14/n
Similar is the case of Injikkuzhi a tribal village within same constituency. The native Kaanis are still fighting for getting land rights to their own ancestral land for years even after passing Forest Regulation Act. Such is the isolation caused by our electoral process

15/n
These are not cases about isolated villages, there are multiple geographical blocks within same constituencies & are expected to elect same person

Map: BhavaniSagar constituency has 3 blocks which are completely different from each other & these affect election results

16/n
The blocks are formed because of variety of reasons: historical, geographical, social, economic reasons.
#Map shows Colachel constituency
Land - owning upper castes like Vellalas & trade oriented ElurChetties dominated flood plains & Eraniel where paddy is predominant crop

17/n
The Nadars who migrated later settled in the less fertile ridges and had converted them into Palmyra forests. Over the last century the Nadar community changed these into Coconut plantations

Coastline is dominated by Paravas (fisherfolk)

18/n
Along with the castes, religious beliefs & based on economic activity, they form complex geographical blocks

Our elections are in such a way that if a particular block is succesfully polarized, then the candidate can win & he/she need not look at the needs of other blocks

19/n
Map shows the voting pattern between 4 parties that contested in Colachel & one can notice how they correlate above mentioned blocks

So a candidate's victory/loss is purely dependent on the success of polarization by that candidate as only a small portion votes rationally

20/n
This communal polarization has been severely affecting our election process as it leaves out a majority of voters from getting represented

Even in a victory in #Kerala, LDF still had to fight against communal polarization done by UDF

Map: UDF was leading in 2021 & religion
21/n
Apart from communal polarization, the constituency results are affected by Urban-Rural divide also.
Tirunelveli&Palayamkottai both belong to #Tirunelveli City but when 2 constituencies were to be created, Villages were added to tirunelveli creating another polarizing divide

22/n
Larger constituencies are more heterogeneous w.r.t caste, religion, economic activity, geography, service provisioning, development when compared to smaller urban constituencies

This makes them more vulnerable to polarization as a lot of villages get disconnected from MLAs
23/n
#Muthukulathoor constituency- literacy rate shows the variation between different villages (54 to 84%) whereas a smaller constituency like Harbour in Chennai's wards vary between 74 to 84% with 81% avg)

Due to larger disconnects, Polarized Large constituencies become weak
24/n
This has reduced economic development in larger constituencies and have aggravated the existing movement towards urban centers

Map shows #TamilNadu's shift in population & night lights centroid indicating this migration

25/n
This is a vicious cycle:
Migration increases population in urban centers& in next delineation, they increase urban constituencies, further weakening mofussil districts, resulting in more developmnt in urban& ppl migrating further creating large unsustainable primate cities

26/n
Since these delineations are done purely based on population counts, non-urban mofussil districts get weakened a lot. Map shows the change in number of constituencies in TamilNadu after last delineation & the pattern can be clearly seen

27/n
The deicision of which village goes into which constituency can the existing voting blocks in the constituency & affects the results

In Tech this called as "Modifiable Areal Unit Problem" i.e when aggregation area is changed, the statistics become different

28/n
If the aggregation boundaries are changed, the result or share of the seats change significantly

When aggregated at an individual level
DMK:ADMK vote share is ~45 : 39
At assembly constituency level it becomes 64:36
At parliamentary const level it becomes 82:18

29/n
When aggregated at Assembly constituency level, DMK wins 4 and ADMK wins 2 in #Tenkasi Parliamentary constituency but when aggregated at parliamentary constituency level, ADMK wins #Tenkasi.

This is because ADMK has polarized two constituencies at a higher level

30/n
Many people widely believe that EVM tampering has to be done at wide scale but when we look at localized polarization pattern, it is clear that a handful of malfunctioning machines that reverse the count of top two is sufficient to change the results

31/n
IMO current model of choosing the representative based on highest number of votes in such complex constituencies should be done away with

Instead,a hybrid method of electing representatives based on proportional representation & minimum vote from blocks should be practiced

32/n
The next delineation happening in 2026 & new parliament building designed to hold 800+ members

The current political system wants to maintain communal polarization friendly electoral process which leads to a form of autocracy that will benefit few places &few people alone

33/n
People arguing this would cause paralysis dont understand differences between legislative & executive branches of govt

Legislative process should be inclusive process with representations from diff communities, engagement, argument, debate & of course it is time consuming
34/n
It is similar to a school Parents-Teachers-Student body election where there are more students but less teachers. Election would always favour students and it wont be a healthy process

For good democracy - population count should not be the only criteria for representation!

Here's a compilation of my #maps which can help you in understanding the #Bengaluru #Water situation a bit better.

Bengaluru is unofficially a hill station which is located nearly a kilometre above sea level. Image
Being in the top of a ridge line, the city is partly within Kaveri watershed and partly in Ponnaiyar (Dakshina Pinakini watershed).
Being on top, water from elsewhere dont flow through Bengaluru but flow outward from the city
Image
Image
Bengaluru right now depends on Kaveri river for water supply. Because of its height, Water is pumped for a height of 1000 feet from the river 100km away from the city Image

Here is the story of how @googlemaps helped me recover items stolen in a moving train from my father.

My father was travelling from Nagercoil to Trichy in sleper class in Nagercoil - Kacheguda express. He had boarded at 1:43 AM from NCJ. The train was relatively empty & another person who boarded along with my dad stole my dad's bag and mobile phone from him, and deboarded the train in Tirunelveli Junction.Image
When my dad realized it, he searched in the train and rang me from his friend's phone at 3:51 AM to inform that his phone was stolen. Luckily, among immediate family members we have location sharing "on" which meant I could track the location of mobile. When I checked it, I realized that the mobile was moving along the track near Melapalayam in Tirunelveli so I deduced that the thief was returning back to Nagercoil in another train.Image
I called my close friend Babin who is also a local DMK (@arivalayam) functionary to help me recover this. And we both went to Nagercoil station to catch the theif. The railway police listened to us and one of them came along. This is a snapshot of Google maps at the time when I was waiting railway station and the theif was still having my dad's phone.Image

Thread:
I'll summarise the #Chennai cyclone event and the flooding issue once again as I feel that there is a lot of misinformation floating around which could guide people and government in wrong way w.r.t future actions
#ChennaiFloods2023
1/n Image
1. The cyclone path had been more or less accurately predicted by IMD, private forecasters

2. The intensity of rainfall however was not clear as per official forecast though it was expected to be heavy, it was not indicated that it would be near record rainfall
3. Though private forecasters including myself had warned about the possibility of extreme nature of rainfall, there was always a doubt and it is difficult for the government to take decisions based on non-official arms like mine and it would be too much of a risk for them Image

Short thread:
#Chennai, lakes, and floods

I have written some threads about the flooding in Chennai, this one would focus specifically on the lake aspect.

#Map below shows the flood forecasted areas in Chennai for an extreme amount of rainfall. If we carefully look into this forecast map, we can see that apart from the major rivers, there are many other paths for the water to run which appear like a tree branching out.

This forecast based on coarser DEM with extreme rainfall & was prepared by my team mates @smkirthiga & pavithra

Pardon the visual quality of maps since I dont have much time to prepare this
Image
If we look at the topography map, the flow paths become clearer as in the map below. When water falls in these places, they are supposed to drain along these streams which appear only during monsoons Image
Let us zoom in further, these "conduits" are the ones that are supposed to carry water. I have added some water flow lines on top of the topography map here near Pallkaranai wetlands Image

Thread:
A recent #satellite image of the sea near #Chennai's Marina beach. There are 3 dots in the image (red, green, blue). What causes it? Image
Satellites have cameras that observe reflection in different spectral bands (including red, green, blue). But they don't observe the same place at the same time and there is a very small lag between them. Meaning between red colour and green colour there is a time difference Image
Most of the objects (like buildings, lakes etc.) that satellites observe don't move that fast in microseconds and hence when image collages are created, it won't show any major difference. But what if objects like Aeroplane which move at say 800kmph is observed? Image

#Thread: A Problem in the making. Two major problems faced by #Bengaluru are flooding and traiffic. But just like any other Indian city, unbridled urbanization is aggravating these crises and is making sure that these problems would stay for longer
1/n Image
In my previous posts, I have explained about the topography and valley system in #Bengaluru. These conveyor belts carry the flood waters of the city. It is across these valleys small dams were built primarily for irrigation purpose (which we now call as lakes)
2/n Image
The problem is that a lot of builtup area came across these valleys. Because of the way we construct, the materials we use, and them behaving as blocks, Bengaluru began having flooding problems as the valleys got blocked
3/n Image
