The UN refugee agency, UNHCR, has called for urgent action before the end of the monsoon season unleashes a new wave of people leaving on boats from the Bay of Bengal.
In the first six months of this year, some 31,000 Rohingya and Bangladeshis departed from the Bay of Bengal on smugglers' boats, a new UNHCR report estimates.
This shows a 34 percent increase in the flow of such people over the same period last year.
And this brings to 94,000 the estimated number of people who have risked their lives making the dangerous journey since 2014, UNHCR spokesperson Melissa Fleming said at a press briefing in Geneva on Friday.
Over 1,100 people are estimated to have died in these waters since 2014, including 370 in 2015.
The UNHCR report traces the events of May 2015 - when such maritime movements and government responses were thrust into the spotlight following the discovery of mass graves of people who died from abuse or deprivation in smugglers' camps along the Thailand-Malaysia border.
Last weekend's discovery of 24 more bodies in north-western Malaysia is a reminder about the ruthlessness of the smugglers, said the office of the United Nations High Commissioner for Refugees.
At least 5,000 people were abandoned by smugglers at sea in May and eventually disembarked in Bangladesh, Indonesia, Malaysia, Myanmar and Thailand.
Another 1,000 people remain unaccounted for but may have disembarked without the knowledge of the authorities. At least 70 people are estimated to have died on the boats that were abandoned in May.
The boat movements have temporarily stopped due to the monsoon rains, which have caused severe flooding in many areas across Myanmar.
However, the maritime departures are expected to resume once the weather improves in the coming weeks.
