Human activities in Asia have reduced elephant habitat by nearly two-thirds since 1700
Despite their iconic status and long association with humans, Asian elephants are one of the most endangered large mammals, Down to Earth reported.Believed to number between 45,000 and 50,000 individuals worldwide, they are at risk throughout Asia due to human activities, such as deforestation, mining, dam building and road construction, which have damaged numerous ecosystems.
My colleagues and I wanted to know when human actions started to fragment wildlife habitats and populations to the degree seen today. We quantified these impacts by considering them through the needs of this species.
In a newly published study, we examined the centuries-long history of Asian landscapes that once were suitable elephant habitat and often were managed by local communities, prior to the colonial era.In our view, understanding this history and restoring some of these relationships may be the key to living with elephants, and other large wild animals, in the future.
How have humans affected wildlife?
It isn’t easy to measure human impacts on wildlife across a region as large and diverse as Asia and more than a century ago. Historical data for many species is sparse. Museums, for instance, only contain specimens collected from certain locations.
Many animals also have very specific ecological requirements, and there often isn’t sufficient data on these features, at a fine scale, going far into the past. For instance, a species might prefer particular microclimates or vegetation types that occur only at particular elevations.
For nearly two decades, I’ve been studying Asian elephants. As a species, these animals are breathtakingly adaptable: They can live in seasonally dry forests, grasslands or the densest of rain forests.
If we could match the habitat requirements of elephants to data sets showing how these habitats changed over time, we knew that we could understand how land-use changes have affected elephants and other wildlife in these environments.
Dramatic declines
Land-use patterns changed significantly on every continent, starting with the Industrial Revolution in the 1700s, and extending through the colonial era into the mid-20th century. Asia was no exception.
For most areas, we found that suitable elephant habitat took a steep dive around this time. We estimated that from 1700 through 2015 the total amount of suitable habitat decreased by 64 percent.
More than 1.2 million square miles (three million square kilometers) of land were converted for plantations, industry and urban development. With respect to potential elephant habitat, most of the change occurred in India and China, each of which saw conversion in more than 80 percent of these landscapes.
In other areas of Southeast Asia — such as a large hot spot of elephant habitat in central Thailand, which was never colonized — habitat loss happened more recently, in the mid-20th century. This timing corresponds to logging concurrent with the so-called Green Revolution, which introduced industrial agriculture to many parts of the world.
Could the past be the key to the future?
Looking back at land-use change over centuries makes it clear just how drastically human actions have reduced habitat for Asian elephants. The losses that we measured greatly exceed estimates of “catastrophic” human impacts on so-called wilderness or forests within recent decades.
Our analysis shows that if you were an elephant in the 1700s, you might have been able to range across 40 per cent of the available habitat in Asia with no problem, because it was one large, contiguous area that contained many ecosystems where you could live. This enabled gene flow among many elephant populations. But by 2015, human activities had so drastically fragmented the total suitable area for elephants that the largest patch of good habitat represented less than 7 per cent of it.
Sri Lanka and peninsular Malaysia have a disproportionately high share of Asia’s wild elephant population, relative to available elephant habitat area. Thailand and Myanmar have smaller populations relative to area. Interestingly, the latter are countries known for their large captive or semi-captive elephant populations.
Less than half of the areas that contain wild elephants today have adequate habitat for them. Elephants’ resulting use of increasingly human-dominated landscapes leads to confrontations that are harmful for both elephants and people.
However, this long view of history reminds us that protected areas alone are not the answer, since they simply cannot be large enough to support elephant populations. Indeed, human societies have shaped these very landscapes for millennia.
Today there is a pressing challenge to balance human subsistence and livelihood requirements with the needs of wildlife. Restoring traditional forms of land management and local stewardship of these landscapes can be an essential part of protecting and recovering ecosystems that serve both people and wildlife in the future.The Conversation.

BASL takes exception to Justice Ganepola being denied a place in SC
… highlights injustice caused to Justice R. Gurusinghe
The Bar Association of Sri Lanka (BASL) has alleged that due to the failure on the part of President Anura Kumara Dissanayake to fill the existing vacancies in the Supreme Court, a Senior Justice of the Court of Appeal, Justice Dhammika Ganepola, retired at the age of 63 without being considered for, or granted, a promotion to the Supreme Court, to which he was well entitled. The BASL pointed out at the time of Ganepola’s retirement there were four vacancies in the Supreme Court.
In a letter dated 17 August, 2026, addressed to President Dissanayake, the BASL declared that the failure to promote and recognise Ganepola’s distinguished judicial service, resulting in his retirement at the age of 63, is indeed a loss to the Judiciary.
A top BASL spokesman told The Island yesterday (30) that the Bar Council, over the weekend, had decided to release the hitherto confidential letter.
The official said that they also wanted to remind the President of his assurance given to BASL, on 12 August, 2026, that vacancies in the Supreme Court and Court of Appeal would be filled as soon as possible, within a month.
The following is the text of the BASL letter, signed by Rajeev Amarasuriya, President, BASL, and its Secretary Nalin De Silva: “We write further to our letters dated 29th December 2025 and 30th June 2026 in relation to the above, to which we have not received any response.
We also refer to our meeting with Your Excellency on 12th August. As discussed during the meeting, there have been vacancies in the Supreme Court since May 2025, and the number of vacancies has now increased to four (04). There are also four (04) vacancies in the Court of Appeal. These are all matters we have already written to Your Excellency about.
Your Excellency informed the BASL Delegation when we met that you would be taking steps to make recommendations to fill these vacancies as soon as possible, within a month.
We write to reiterate the importance of giving due consideration to the criteria set out in our aforesaid letter dated 29th December 2025. We also wish to emphasise that, in making judicial appointments and promotions, seniority should be given due priority, in keeping with longstanding practice, until such time there are objective and defensible guidelines governing the assessment of merit.
The only justifiable departure to this criterion would be where there exists a specific and recognized demerit in respect of the particular Judge concerned or such other known compelling circumstances that are objectively identifiable such as where a Judge has previously been overlooked for promotion unfairly or conversely, where a Judge has been unfairly previously granted promotions above others.
This approach will safeguard both the integrity of the Judiciary and the trust reposed in it by the public.
Further, while there has been considerable discussion and representation by the Government regarding the importance of retaining experienced judges, as reminded to Your Excellency at our said meeting that, only a few months ago on 8th May 2026, a Senior Justice of the Court of Appeal, Justice Dhammika Ganepola, retired at the age of 63 without being considered for, or granted, a promotion to the Supreme Court, to which he was well entitled, and in which there were four vacancies at the time.
The failure to promote and recognise his distinguished judicial service, resulting in his retirement at the age of 63, is indeed a loss to the Judiciary.
We also drew Your Excellency’s attention at the said meeting to the fact that the Senior-most Justice of the Court of Appeal, Justice R. Gurusinghe, who joined the Judicial Service in 1996, who also Acted in the Office of President of the Court of Appeal (appointed by Your Excellency) on 11th May 2026, is due to retire at the end of this month. In fact, we learnt through the Media that Her Ladyship then Chief Justice Justice Murdu Fernando, PC, had previously in July 2025 recommended to Your Excellency the promotion of Justice R. Gurusinghe to the Supreme Court, but the same is pending from that time.
He too is well deserving of promotion to the Supreme Court and has already been recommended by the former Chief Justice, and his case must also receive due and urgent consideration before his impending retirement.
We hope that Your Excellency will take due note of and give due regard to the concerns of the Bar, as well as to the established principles, practices and conventions governing judicial appointments, when taking steps to fill these vacancies.
On this, Your Excellency is already open to the accusation that these vacancies have been kept open, to fill with favourites of the Government which is yet another serious indictment on the independence of the judiciary which accusation would be confirmed if recommendations are made outside established practice.
Moreover, the BASL expresses grave concern that withholding promotions of Judicial Officers for extended periods of time places undue pressure on Judicial Officers in the discharge of their duties and constitutes both directly and indirectly, interference with the independence of the Judiciary, in addition to the strain obviously caused to the dispensation of justice in other Courts and the stifling and delay of career progression of Judges legitimately entitled to promotions.
We do hope that Your Excellency would take due note and cognizance of the foregoing when effecting these judicial promotions which have been long overdue and which have already adversely impacted the efficiency and effectiveness of the administration of justice.”
The BASL has copied the letter to Prime Minister Dr. Harini Amarasuriya, Speaker Dr. Jagath Wickremaratne, Opposition Leader Sajith Premadasa and all members of the Constitutional Council.

Sajith challenges govt. to hold PC polls
Opposition Leader Sajith Premadasa on Saturday (29) challenged the government to hold the long-delayed Provincial Council elections, saying the polls would provide an opportunity to gauge the level of public support enjoyed by the administration.
Addressing a farmers’ meeting in Tissamaharama, Hambantota, Premadasa also criticised the latest Rs. 17 per kilogram increase in wheat flour prices, warning that it would push up the prices of bread, bakery products and other flour-based food items and place further pressure on households already struggling with the rising cost of living.
He said Sri Lanka ranked 120th among 130 countries in an international comparison of minimum wages, arguing that wages remained inadequate to meet the escalating cost of living.
Premadasa also questioned official assessments of living standards, asking whether a person could survive for an entire month on Rs. 17,315, a figure he attributed to the Department of Census and Statistics.
He claimed that between 30 and 40 percent of the population was living in poverty and called for a clear programme to help affected families improve their economic conditions.
Turning to the proposed 22nd Amendment to the Constitution, which seeks to increase the retirement age of superior court judges, the Opposition Leader accused the government of attempting to undermine judicial independence and interfere with democratic institutions.
He also criticised the government’s handling of poverty, employment, agriculture, healthcare and investment, saying more effective measures were needed to provide relief to people facing economic hardships.Premadasa called for stronger policies to attract foreign direct investment and urged the government to formulate a national strategy for developing the tourism industry.
