UNDP-Cambodia and Asean mine action centre renew partnership to accelerate knowledge sharing, collaboration
PHNOM PENH (Xinhua): The United Nations Development Program (UNDP) in Cambodia and the Phnom Penh-headquartered Asean Regional Mine Action Centre (ARMAC) have renewed partnership to accelerate knowledge sharing and collaboration on mine action, said a joint press release on Monday. Alissar Chaker, UNDP resident representative in Cambodia, and Buth Rothna, executive director of ARMAC, signed a new memorandum of understanding (MoU) last Friday to enhance technical cooperation and knowledge sharing on mine action. "This collaboration aims to support ARMAC's efforts in promoting peace and security and reducing casualties from landmines and Explosive Remnants of War (ERW) in affected Asean member states," the press release said. Both sides would accelerate regional coordination, partnership building, knowledge sharing, and exchange of good practices in mine action, particularly in advocacy, clearance and land release, victim assistance, and risk education, it added. Chaker said that over the past 20 years, Cambodia has made remarkable progress in strengthening mine action management, developing policies, legal frameworks, standards, and information systems for land clearance and release, raising public awareness and promoting risk education on ERW, as well as supporting victim assistance. "The Kingdom's hard-earned wealth of knowledge and expertise is invaluable to other mine-affected Asean countries and for strengthening peace and security across the region," she said. Rothna said the MoU reflected the spirit of Asean solidarity and shared commitment to a mine-free region. "By combining ARMAC's regional mandate and technical coordination role with UNDP's global presence and development expertise, we are poised to elevate cooperation across ASEAN to new heights," she said. Asean (the Association of Southeast Asian Nations) groups Brunei, Cambodia, Indonesia, Laos, Malaysia, Myanmar, the Philippines, Singapore, Thailand, and Vietnam. - Xinhua

Rock on: How crushed stone could help fight climate change
By Sara HUSSEIN From sugar plantations in Brazil to tea estates in India, crushed rock is being sprinkled across large stretches of farmland globally in a novel bid to combat climate change. The technique is called Enhanced Rock Weathering (ERW) and aims to speed up the natural capture and storage of carbon dioxide -- a planet-warming greenhouse gas. It is potentially big business with tech giants, airlines and fast fashion firms lining up to buy carbon credits from ERW projects to "offset" or cancel out their own emissions. What is ERW? ERW aims to turbocharge a natural geological process called weathering. Weathering is the breakdown of rocks by carbonic acid, which forms when carbon dioxide in the air or soil dissolves into water. Weathering occurs naturally when rain falls on rocks, and the process can lock away carbon dioxide from the air or soil as bicarbonate, and eventually limestone. ERW speeds the process up by using quick-weathering rocks like basalt that are ground finely to increase their surface area. How effective is ERW? ERW is still a fairly new technology and there are questions about how much carbon it can remove. One US study found applying 50 tons of basalt to a hectare of land each year could remove up to 10.5 tons of carbon dioxide per hectare over a four-year period. But scientists applying basalt to oil palm fields in Malaysia and sugarcane fields in Australia measured much lower removal rates. "Field trials are showing that there have been overestimates of the amount and rate captured," said Paul Nelson, a soil scientist at James Cook University who has studied ERW. Rates depend on variables including rock type and size, how wet and hot the climate is, soil type and land management. And measuring the carbon captured is difficult. The most popular technique measures "cations", positively charged ions that are released from the rock during weathering. But those cations are produced regardless of which acid the rock has reacted with. "If there are stronger acids than carbonic, then it will react with those," said Nelson, so measurable cations are produced even when carbon dioxide is not captured. That doesn't mean ERW is pointless, said Wolfram Buss, a researcher on carbon dioxide removal at the Australian National University, just that it needs to be carefully calibrated and measured. "There is no doubt that this technique works," he said. "However, to be sure how much carbon dioxide we actually remove, more funding is required to do fundamental studies." Are there other benefits? The added rock increases soil alkalinity, which can boost crop growth, soil nutrients and soil formation. Basalt is both naturally abundant and often available as a byproduct of quarrying, lowering the costs of the process. Experts note that even if the rock reacts with other acids in the soil, failing to lock away carbon dioxide at that stage, it can still have planetary benefits. That is because acids in the soil would otherwise eventually wash into rivers and the sea, where acidification leads to the release of carbon dioxide. If the rock neutralizes that acid in the soil, "you've prevented carbon dioxide being released from the water into the atmosphere downstream", said Nelson. The scale of those possible "prevented" emissions is not yet clear, however. What are the risks? ERW is broadly considered safe since it merely speeds up an existing natural process. However, some quick-weathering rocks have high levels of potentially poisonous heavy metals. Scattering finely ground rock also requires appropriate protective gear for those involved. But the main risk is that incorrect measurements overestimate captured carbon. Some projects are already selling carbon credits from ERW. If a company buys an ERW credit to "offset" its emissions but the process captures less than projected, it could result in net higher carbon dioxide put into the atmosphere. Where is ERW being done? Projects are happening in most parts of the world, including Europe, North America, Latin America and Asia. Earlier this year, a project in Brazil announced it had delivered the first-ever verified carbon-removal credits from an ERW project. The process is being used or trialled in agricultural settings from tea plantations in India's Darjeeling to U.S. soy and maize fields. What investor interest is there? An ERW startup -- Mati Carbon, working in India -- won the $50 million X Prize for carbon removal projects earlier this year. In December, Google announced what was then the world's biggest ERW deal, for 200,000 tons of carbon removal credits, to be delivered by the early 2030s by startup Terradot. The cost of the deal was not disclosed but a separate agreement by Terradot with a company representing firms including H&M sold 90,000 tons for $27 million. © 2025 AFP
