Are there too many elephants in India? That’s the question at the crux of a debate between wildlife experts on whether the government should use contraceptive measures to manage the population of four species including elephants.
If you go by the country’s first ever synchronised Elephant Census conducted in 2017, there are 27,312 elephants across 23 states.
But experts have argued that this number does not give a complete picture, mainly because of issues with the different methods used to estimate the population of elephants. The government itself said in the 2017 census report that the results should be interpreted with caution.
It’s not just elephants—in India, accurate nation-wide population data on most animal species, including tigers, is hard to arrive at because of problems with the methodology used to track their numbers.
This is a major reason why the environment ministry’s proposal to use immunocontraceptives has met with resistance from many experts.
Apart from Asian elephants, these contraceptives—vaccines that, when injected into the female of the species, will prevent eggs from being fertilised—will also be used on rhesus macaques, wild boar and nilgai.
The 10-year project to develop an immunocontraceptive was approved in 2017, with a budget of Rs10 crore. According to Vinod Mathur, the director of the Wildlife Institute of India (WII), the nodal agency for the project, it will “soon be implemented on a pilot basis in a phased manner”.
While there has been an increase in human-elephant conflict over the years, is it right to argue that this is because the population of elephants has become burdensome?
When asked how much we know about elephant density and distribution across the country, Dr. Devcharan Jathanna, associate director of Conservation Science at NGO Wildlife Conservation Society-India (WCS), said “very little”.
There is long-term elephant population monitoring data from individual protected areas such as Nagarahole, Bandipur, Bhadra and Wayanad and some estimates from Kaziranga, Jathanna explained.
“But we don’t actually know how many elephants there are across elephant distributional ranges, either at the state or national level,” he said.
This is because dense vegetation in India’s forests only allows minimal detection of wildlife, making it difficult to accurately assess their population through direct observational methods. That’s why India uses estimation techniques that depend on sampling.
So what, then, is the rationale for injecting immunocontraceptives—a technology as yet untested in India—into Asian elephants, a species that is on the International Union for Conservation of Nature’s list of endangered animals?

Much rather have 1.3 billion of them rather than us, but that could just be me.
