Advanced technology sees Cambodian rangers detect almost 800 hectares of encroached forests
PHNOM PENH: Nearly 800 hectares of forest land that had been encroached upon and planted with various crops in protected areas of Siem Reap province were identified in 2024 and 2025, thanks to the use of modern technology and information systems.
The Ministry of Environment explained how park rangers in natural protected areas are using satellite imagery systems and advanced drones to monitor and prevent natural resource crimes.
In Siem Reap province, this technology enabled rangers to inspect 77 specific locations. Among them, 32 locations were found to be encroached forest areas, totalling 459.64 hectares. In addition, 28 areas totalling 331.65 hectares were used for illegal crop cultivation.
'The use of information systems and modern equipment strengthens the management of natural protected areas. Park rangers are using satellite image technology and drones to effectively monitor, prevent and suppress natural resource crimes,' said the ministry.
Rangers, in cooperation with military forces in the Siem Reap operational zone and members of local protected area communities, conducted field inspections at 67 locations in the Phnom Tnaot–Phnom Pok Wildlife Sanctuary. Of these, 40 locations showed signs of encroachment, covering more than 428 hectares.

Rangers have forwarded 15 cases of natural resource crimes to the Siem Reap Provincial Court, including 2 cases involve crimes they witnessed, with 6 suspects and other related 13 cases involving 7 suspects.
The Siem Reap Department of Environment manages 8 protected areas, totalling 283,999.27 hectares. Management of these areas is supported through cooperation with local military forces, district-level unified command committees and protected area community committees.
According to the 'Core Strategy – Pillar 2, Priority 1', building digital infrastructure and equipping modern facilities, tools and materials for administrative work is stated as a crucial part of the Circular strategy on Environment.
This aligns with the government's environmental policies and action plans, which emphasises the use of advanced technology to monitor, analyse and respond swiftly to environmental issues. These include satellite data collection, drone deployment for verification and targeted enforcement in priority areas.
In 2024 and 2025, the ministry provided satellite-based maps of protected areas to sub-national administrations and local authorities for joint management efforts. Additionally, it distributed 47 drones to each of the kingdom's provincial environment departments. Departments with protected areas have also received support from NGOs and development partners, including more equipment and drones. - The Phnom Penh Post/ANN

Thai prosecutors drop Royal insult case against US academic
Paul Chambers photographed at the Phitsanulok Provincial Court. -- Photo: The Isaan Record via Laotian Times BANGKOK (Bloomberg): Thai prosecutors dismissed charges against an American academic accused of insulting the country's monarchy, after his arrest was criticised by the US and cast a shadow over tariff talks. Prosecutors dropped royal insult and computer crime charges against Paul Chambers, a lecturer at Naresuan University in northern Phitsanulok province, and will inform police of the decision pending any objection, the Office of the Attorney General in a statement. No clear reasons were cited in the statement for the decision. Chambers, who has lived in Thailand for more than 30 years, was accused by a regional army unit of breaking the royal insult, or lese majeste, law over comments about the powers of the prime minister and the monarchy in a blurb promoting an international webinar last October where he was a speaker. Chambers has denied the charge. The case is seen as linked to a delay in talks between Thailand and the US on reducing a Trump administration plan to slap a 36% tariff on the Southeast Asian nation's exports. Talks initially slated for late April were postponed after Washington asked Bangkok to address a set of "issues' related to trade, government officials have said. The extent of the issues have not been made clear by Thai officials, and no new date has been set for talks to be held. The US Department of State said in a statement on April 8 that it was alarmed by his arrest and the case reinforced its longstanding concerns about the use of the lese majeste law in Thailand. The term refers to Article 112 of the Thai criminal code, which punishes anyone who "defames, insults or threatens' Thailand's king, queen, heir-apparent or regent by up to 15 years in prison. Chambers, an expert on the Thai armed forces, was released from pre-trial detention on bail days after being arrested. The bail conditions included a ban on overseas travel without the court's permission and confiscation of his passport. He was also required to wear an electronic monitoring device around his ankle. Formal charges have been filed frequently under Article 112 over the past two decades, resulting in many prominent academics and political activists fleeing Thailand and seeking political asylum abroad to avoid prosecution. -- ©2025 Bloomberg L.P.

Soccer-Rangers condemn shotgun banner during Old Firm derby
Soccer Football - Scottish Premiership - Rangers v Celtic - Ibrox, Glasgow, Scotland, Britain - May 4, 2025 General view during the match Action Images via Reuters/Lee Smith (Reuters) - Rangers have condemned a banner displayed by their supporters during Sunday's Scottish Premiership 1-1 draw with rivals Celtic at the Ibrox Stadium that appeared to show former manager Graeme Souness holding a double-barrel shotgun. A banner, reading "Take aim against the rebel scum" was part of the tifo display held up by a large section of the crowd in the Copland Stand before kick-off, unfurled as players emerged from the Ibrox tunnel. The image was based on a real photograph of Souness taken in 1982 ahead of Scotland's World Cup match against New Zealand in Spain. Rangers also condemned a supporter who threw a glass bottle onto the pitch during the derby, which landed near Celtic goalkeeper Viljami Sinisal. "This behaviour has no place at our stadium. Steps have already been taken to identify the person responsible and the club will take the strongest possible action once their identity is confirmed," a Rangers spokesperson said on Sunday. "We also acknowledge that the tifo displayed prior to kick-off crossed a line and was unacceptable. Our approach to supporter displays has always been built on trust, with the responsibility placed on groups to exercise good judgement. "We will reflect on how these displays are managed and engage with supporter groups to ensure the right balance of trust, responsibility and oversight is maintained moving forward." A police spokesperson told BBC Scotland that they are aware of the banner and enquiries are ongoing. In March, UEFA fined Rangers 30,000 euros ($34,029)and issued a suspended partial stadium closure over a banner displayed during their Europa League match against Fenerbahce. The banner, which read "Keep woke foreign ideologies out. Defend Europe," was deemed "racist and/or discriminatory" by UEFA.
