Introduction
Tamil Nadu Government had notified Coimbatore Elephant Reserve in the year 2003. Mukurthi National Park, Nilgiri South Forest Division and Coimbatore Forest Division are its components. Coimbatore Forest Division occupies a major portion of this Reserve.
Earlier research on elephant migration in Coimbatore Forest Division from 1993-2014 (22 years) have indicated an increasing trend in Human Death and Injury due to elephant attacks from the year 2000.
“ Totally 96 human deaths due to
elephants were recorded during the past 22 years (1993-2014). Of which, 2013
attributed highest deaths (n=18) followed by 2010 (n=17) and 2012 (n=11). From
1999 to 2009 over a period of 10 years, the casualty ranged from just 1-8. On the contrary the trend has suddenly
changed as 17 human deaths had occurred during 2010 and the subsequent years of
2011 to 2013, the casualty ranged from 7-18 (Fig-1). It is important to note that
any human deaths were not reported during 1993 to 1998. Wilcoxon rank test
reveals that there is no difference in human death before the year of 2000
(Z=1.265, P+0.206). Interestingly, there is a significant difference in human
death after 2000 (Z=2.805, P=0.005). ( K.Ramkumar et al., “Consequences of land
use land cover changes in elephant migratory route of Coimbatore Forest
Division, Tamil Nadu, India “, in International Symposium on Ecology and Health
Management of Asiatic Elephant, November 2015)
The authors of the above cited paper summarise the reasons for
the increasing trend of human deaths in Coimbatore forest Division and also
propose the possible solutions for overcoming them as follows:
“ Human deaths caused by elephants
increased drastically in last five years (ref.year 2014) in Coimbatore Forest
Division. Conversion of each Land Use Land Cover(LULC) types will obstruct and
divert the elephant movement from the actual Elephant Migratory Route (EMR) on
their own way and lead to severe Human Elephant Conflict (HEC). Thus land use
changes should be controlled effectively in EMR in order to control HEC issues
in this division. Solar Fence, Elephant Proof Trench (EPT) and other preventive
methods can be considered as only short term, which may provide only some
immediate relief. In addition to EPT, modern tools using mobile communications
such as mobile alerts and alarms and early warning system about elephant
presence can be tried. As long term measure, intensive management of elephant
migratory routed=s is needed. Also, management strategies in this division
should be aimed at regulating land use changes in private lands at least 2 km
from forest boundary, habitat improvement in foothill forests and detailed
research on factors of human elephant conflict and new techniques on control
measures. Private lands located at least 200m from foothill forest should be
freed from all sort of physical barriers. Water sources could be provided along
every 5 km in the forest foothills during summer, to negate the need for the
elephants to move further inlands into human areas.”
Human death and injury due to elephant attacks have dramatically
increased after 2014.

This alarming increase in Human Death is especially noted in
Boluvampatti, Coimbatore and Periyanaickenpalayam Forest Ranges of the
Division. This paper deals with the human mortality and morbidity trends in
Boluvampatti Range and puts forward a hypothesis that explains the reason for
this increase in the trend.
Materials and Method
Data pertaining to human death and injury due to elephant attacks for the period 2011-2021 in Coimbatore Forest Division was obtained from the Tamil Nadu Forest Department through RTI. Maps of BNEGEL and NSVAEL, Coimbatore Elephant Reserve, Coimbatore Forest Division with its seven Ranges, Boluvampatti Forest Division with its three geographical regions and 10 beats were prepared using QGIS software. Data were sorted and analysed using Excel and JASP software. The result was compared with the results of earlier researches.

Discussion
The proportion of humans injured and dead due to elephant attacks from Boluvampatti Range of Coimbatore Forest Division has increased from 22.22% to 34.08% of the total number of human deaths/injury in Coimbatore Forest Division.
The increase in death rate in Boluvampatti Range is due to its steep rise in the Northern (+171.89% of the previous period) and Western Regions (+50.86% of the previous period) from the year 2016. Death rate in the southern region of Boluvampatti has reduced (-16.89% of the previous period) during this period.
It should be remembered that this increase in HEC leading to a sharp increase in human death rate in this region was indeed anticipated in the letter written by the District Forest Officer, Coimbatore Mr.Thirunavukkarasu IFS to the Principal Chief Conservator of Forests in the year 2012 itself. (R.C.No.VI/8120/2011 Dated:17.08.2012)
Construction of Adi Yogi Statue of Isha Yoga Center began in the year 2016. Construction of walk path and vehicle parking lot for this Statue obstructs the movement of elephants from Sadivayal Elephant Habitat in the west to the migratory path extending east from Narasipuram. Similarly, various buildings of Isha Yoga Center being constructed north east of the core Isha habitation obstructs the movement of elephants from Narasipuram to Sadivayal elephant habitat. As there are no other land use land cover changes in this area other than these two mega construction activities in this period, it is most probable that they are the reasons for the alarming rise of human deaths and injuries due to agitated elephants.
Conclusion
Sadivayal Elephant Habitat is the only major flat forested land (500 m above mean sea level) south of Karamadai Range of Coimbatore Forest Division where food, water and space is available in plenty for the elephants that are migrating seasonally from Brahmagiri-Nilgiri-Easter Ghat Elephant Landscape to the Nilambur-Silent Valley-Attapadi Elephant Landscape. It has an area of 14 square kilometers and is bestowed with a perennial water source (Noyyal River). This forested land has about 7 tribal settlements and has existed here for more than 1000 years. No human death have been reported from this area before the year 1996. Following the construction of Karunya University and Chinmaya School in the eastern and Isha Yoga center in the north eastern directions during this period, human deaths due to elephant attacks have started occurring in this area. Construction of Adi Yogi Statue and related structures from the year 2016 has increased this phenomenon many fold.
Considering and comparing the history of the HEC scenario in the neighbouring Thadagam Valley for the same period (2011-2021) would be useful for policy makers. 3 humans died in the period between 2011 and 2015; whereas 29 individuals were either dead or injured between 2016 and 2021. The 200 plus illegal brick kilns and 800 plus illegal brick earth quarries were closed and sealed on 19.03.2021 by the District Administration following an Order from the Madras High Court dated 10.02.2021. Operations of 1000 Lorries, 800 Tipper Lorries and 800 JCBs were halted that day. In the months that followed this closure and end of the operations in the year 2021, the Valley was to witness just 1 elephant attack on an individual, from which he survived. The Valley was free from HEC for the entire year of 2022.
HEC data on Boluvampatty Valley for the period 2011-2021 should be considered and analysed seriously by the State's policy makers. The data paints a very grim picture for the future of the largest population of Asian Elephants in the world and also human beings living in that region. Rereading the letter written by the DFO, Coimbatore to the PCCF dated 17.08.2012 regarding the very real possibility of increased HEC in this region because of the fast expanding construction of buildings, becomes very imperative today. Conducting an Environmental Impact Assessment for Isha Yoga Center by an Expert Body is the need of the hour. Exempting it from this Assessment is certainly not warranted.
