“Elephants are headed our way,” said the text. “Please let others know.” 

Ganesh Raghunathan received this message, one of eight SMS messages that day from villagers across the Valparai plateau in southern India. 

As he does each day, Ganesh added the update to his map of the locations of elephant herds that are monitored daily, in order to send out the daily alerts of these locations. 

Each afternoon at 4 p.m., Ganesh sends out text messages with the locations of elephants to all registered villagers living near the herds’ current locations, as part of a larger, ingenious program by the Nature Conservation Foundation to protect both people and elephants. 

The problem 

Indian elephants (Elephas maximus indicus) once freely roamed the rich mid-elevation evergreen forests of the Valparai plateau in the Western Ghats, one of the world’s mega biodiversity regions, but they can’t move the way they used to. Ever-increasing commercial plantations and settlements have become obstacles to the daily and seasonal movements of elephants. 

Forests across the plateau have been largely replaced by plantations of tea, coffee, and eucalyptus (cut and burned to process the tea). The three crops give the region a bright green sheen, but none of these three perennial exotic plants is palatable to elephants, so for them it’s like being in a desert, with small isolated patches of edible native plants in the rainforest fragments scattered among the large plantations. 

The conversion of a diverse natural forest into monoculture cropland has both reduced and fragmented the habitat available to elephants, requiring them to walk long distances to reach food and shelter found in the forest islands among the plantations, while trying to avoid people. The industry has attracted nearly 70,000 people who harvest the wood, tea leaves, and coffee beans, making these areas — particularly the tea plantations — full of human activity during the day. 

People and elephants in this region tend to leave each other alone, since elephants don’t eat tea or eucalyptus, and only occasionally nibble coffee beans. Elephants avoid people when possible, creating an environment in which people are most likely to run into elephants moving from one fragment to the other at night, when neither party can see the other in advance. 

While these unexpected nighttime encounters rarely result in harm, they still are the primary instance of elephant-caused human injury. If elephants are surprised by the sudden appearance of a person in front of them, they may panic and charge. However, with advanced warning of elephant locations, most conflicts can be avoided. Armed with knowledge, people can take alternative routes, or they can make noise at the edge of their village to get elephants to change direction. 

Locating and broadcasting 

Researchers of the Nature Conservation Foundation (NCF) began working in 2002 to understand elephant ecology and behavior, and their interactions with people residing in the plantations. Through their study, they learned that a lack of timely information on elephant whereabouts was the primary reason for the surprise encounters that can lead to human injuries or fatalities. With ensuring the safety of both species as their primary goal, the NCF team has won the support of the region’s approximately 46 estates that are managed by seven major plantation companies while engaging villagers to help them develop and implement a creative, low-budget elephant warning system. 

Locating elephants: Each day, three NCF team members span out to look for the herds, taking into account location information collected by collaborating villagers, and report the locations of those they find. In addition, the team receives calls or texts from local people and Forest Department field staff with information on elephant whereabouts. Based on that information, the team uses three separate activities to inform people of elephant movements and presence: a bulk text messaging system, streaming information on the local television channel, and alarm beacons in key villages. 

The bulk SMS/text system: Research conducted by NCF’s Ananda Kumar between 2002-2007 found that elephants in the area are most likely to be found within two kilometers (1.2 miles) of their previous day’s location. Because of this, villagers living within a two-kilometer radius of any recent elephant alert locations who have signed up to receive text messages of herd whereabouts will receive an alert. The locals, in turn, spread the word to friends and families, all of whom can then take necessary precautionary measures while stepping out that evening. 

Local TV: The NCF team also broadcasts elephant sightings on TV. Viewers of the local television channel can watch elephant locations being streamed across their TV set on a continuous basis. However, as people have upgraded to DTH (Direct To Home) and satellite television over the local network, this messaging form is reaching fewer viewers. 

Alarm beacons: Not every resident of Valparai has registered to receive daily text messages, or even owns a mobile phone or TV, so the NCF team created a new application for their own mobiles that communicates to an entire village through centrally located signal beacons. These beacons are placed in strategic, elevated locations to provide maximum visibility to both residents and visitors to the area, who would otherwise be unaware of elephant presence. When elephants are known to be less than one kilometer (0.6 miles) from an alarm beacon, a call or text message sent by either NCF or one of two designated villagers turns on the beacon, which emits a blinking red light. Any of the three callers can also call to turn off the light, and, to be sure that they working correctly, NCF checks all light operations every morning. 

Many fatal and injurious elephant-human encounters occur as people walk home from bus stops. To address this, NCF developed a fourth component to the warning system that streams SMS-based announcements of elephant whereabouts across digital signs displayed on local buses to inform riders that they should be particularly careful or perhaps even avoid certain stops where elephants are present. 

The system works! 

The elephant location advisories, which initially reached 700 registered families (recipients must request to be put on a list), now reach 2,800 families, and continues to grow. Of those to register recently, one resident joined after elephants entered his village and broke open the door and window of a building to reach grain stored inside. The damaged building was a workers’ club surrounded by houses, which were not damaged. The elephants, crossing between forest patches, had entered the area after breaking through an electric fence around it. 

Community involvement in receiving text messages, reporting elephant locations, and sharing information with neighbors has increased awareness, developed a sense of precaution, and generated ways to effectively avoid encounters with elephants, which, in turn, have helped locals plan their outdoor activities more effectively and safely. The warning system has reduced the number of injurious elephant encounters, with no elephant-caused human deaths or injuries reported in the region in all of 2013. However, in February of this year, in two separate incidents, people who ignored warnings and unexpectedly encountered elephants in the early morning hours were killed, underscoring the importance of continuing to inform local people not only of elephant locations but also on precautionary measures they should take to avoid harm if they do encounter one. 

What’s at stake? 

The safety and well being of the 70,000 people living among the Valparai region’s tea estates, as well as the ability of the elephant herds to move freely among areas with food, shelter, and water, depend on maintaining peaceful coexistence between the two species. 

The situation in Valparai is actually simpler than those of regions where elephants consume and damage food crops. Here, the safety of people and buildings, which often contain stored food, is of primary concern. 

According to Kumar, even when food crops are involved, early warning of elephant presence is critical to avoiding human injury and destruction of crops and property. With proper training, local residents can usually keep elephants from entering crop areas, which is easier than trying to drive them out once are already in a field. Kumar’s team has recently been contacted to help “negotiate” terms for peaceful coexistence between humans and elephants in the Western Ghats’ largest conservation landscape – the Satyamangalam forest division of Tamil Nadu state, adjoining the Nilgiri Biosphere Reserve. Their contribution to innovative conflict resolution will be critical to long-term survival of a viable regional elephant population. 

Over 80 percent of Indian elephant range is outside parks and reserves, with even herds that largely reside inside protected areas frequently moving outside to forage. Ultimately, the survival of these iconic, endangered animals depends on their ability to find food, shelter, and water in an increasingly human-dominated landscape. Elephants generally attempt to avoid people; this benevolence needs to be matched by human behavior that facilitates, rather than hinders, elephant movement and access to critical resources. 

In regions shared by elephants and humans, is important to understand elephant behavior, educate local people about ways to reduce conflict, and implement careful land-use planning that enables elephant movement among forest patches. Innovative effort to facilitate this, such as the work done by NCF*, is a major step towards minimizing stress and associated hostile interactions, and consequently saving the lives of both species that call this region home. 

*Elephant Family, Mohamed bin Zayed Species Conservation Fund, GUPSHUP Enterprises for SMS, Tamil Nadu Forest Department, as well as plantation companies and the people of Valparai, have all provided critical support to NCF’s human-elephant conflict prevention work.
