More than 50 lakh large farmland trees vanished between 2018 and 2022 in India: Study
New Delhi (PTI): More than 50 lakh large farmland trees vanished between 2018 and 2022 in India, partly due to altered cultivation practices, revealing a "concerning trajectory," new research published in the journal Nature Sustainability has found.
Researchers said that "an observable trend was emerging" wherein agroforestry systems are being replaced with paddy rice fields, even as a certain loss rate could be found to be natural.
Large and mature trees within these agroforestry fields are removed, and trees are now being cultivated within separate block plantations typically with lower ecological value, they said.
Block plantations, usually involving fewer species of trees, were found to have increased in numbers which some villagers from Telangana, Haryana, Maharashtra and other states confirmed via interviews.
The team, including researchers from the University of Copenhagen, Denmark, explained that the decision to remove trees is often driven by perceived low benefits of the trees, coupled with concerns that their shading effect, including that of Neem trees, may adversely affect crop yields.
Boosting crop yields also contributed to the expansion of paddy rice fields, further facilitated by water supply which was augmented by the establishment of new boreholes, the authors said.
"This finding is particularly unsettling given the current emphasis on agroforestry as an essential natural climate solution, playing a crucial role in both climate change adaptation and mitigation strategies, as well as for livelihoods and biodiversity," the authors wrote.
Agroforestry trees are a vital part of India's landscapes as they generate socio-ecological benefits, along with being a natural climate solution owing to their ability to absorb carbon dioxide from the air.
However, despite their importance, the lack of robust monitoring mechanisms has contributed to an insufficient grasp of their distribution in relation to management practices, as well as their vulnerability to climate change and diseases, the researchers said.
For the study, the team used AI-based deep learning models for detecting individual non-forest trees for each year. By tracking the tree crown over the years, they then analysed the changes. Crowns of multiple trees together form a canopy.
The researchers mapped about 60 crore farmland trees, excluding block plantations, and tracked them over the past decade.
They found that around 11 percent of the large trees, each having a crown size of 96 square metres and mapped in 2010/2011, had disappeared by 2018.
"Moreover, during the period 2018–2022, more than 5 million large farmland trees (about 67 square metres crown size) have vanished, due partly to altered cultivation practices, where trees within fields are perceived as detrimental to crop yields," the authors wrote.
The researchers clarified that while the findings may appear to contradict official reports and studies showing that tree cover has increased in recent years, they reported only gross losses and did not look at tree gains as a separate class.

NCB seizes over 39 kgs of Alprazolam in Telangana; three arrested
Hyderabad (PTI): A gang allegedly manufacturing and trafficking Alprazolam drug in bulk quantity illegally in Siddipet district of Telangana has been busted, NCB officials said on Sunday.
Three people, including a Chemist freelancer, have been arrested in this regard, they added.
As much as 39.470 kgs of Alprazolam worth around Rs 12 crore and Rs 85.36 lakhs in cash were seized on May 15, the Hyderabad Zonal Unit of the Narcotics Control Bureau (NCB) said in a release.
On the basis of specific information, NCB officials intercepted two four-wheelers and two persons when they were exchanging Alprazolam illegally without any valid license.
The search resulted in the recovery of 39.470 kgs of Alprazolam and Rs 85,36,200 in cash, found to be proceeds of Alprazolam sales, it said.
On the basis of a disclosure made by one of the accused about the supplier of the Alprazolam, NCB officials apprehended another person from Hyderabad.
On interrogation, it was revealed that the person who supplied the drug had studied MSc Chemistry. He is working as a chemist freelancer, and he disclosed that he manufactured the seized Alprazolam clandestinely in his laboratory at Prashantnagar here, the NCB said.
All three persons "confessed to their involvement in manufacturing and trafficking of Alprazolam illegally" and were arrested under the relevant sections of the NDPS Act 1985.
Preliminary investigation suggested that they transacted around 150 kgs of Alprazolam over the last five years.
All three accused were produced before the magistrate and sent to judicial custody. Further investigation is ongoing, the release added.
