New environmental monitoring technologies used for this year's Hajj
Jeddah: Saudi Arabia's National Center for Environmental Compliance has begun using new satellite monitoring technologies to protect the environment for this year's Hajj.
The NCEC uses satellite data to monitor and analyze environmental media, including air, water and soil quality.
The center relies on satellites to monitor environmental challenges across wide geographic areas at high speed, enabling emergency teams to quickly reach affected sites.
Hani Al-Subhi, director-general of the Makkah Region branch, spoke to Arab News about the center's use of satellite technology.
'These technologies help pinpoint the precise locations of environmental challenges, facilitating a rapid response and enhancing the provision of a healthy, pollutant-free environment for pilgrims,' he said
Meanwhile, Abu Talib Zaki, a technical expert in monitoring, spoke about how the center cooperates with King Abdulaziz City for Science and Technology to collect two types of satellite imagery.
The first is passive remote sensing, which measures reflections of light emitted from other objects.
The second is active remote sensing, which uses light from the satellite itself to create images.
The spatial resolution of the images used reaches 30 cm, meaning that each pixel of the image covers 30x30 cm, allowing for high-precision monitoring of environmental phenomena.
The National Center for Environmental Compliance earlier this week completed 90 percent of the preemptive inspections to ensure the safety of water, air, and soil for Hajj.
Monitoring efforts will continue until pilgrims complete their rituals in a healthy, pollutant-free environment.
The center also uses nine air quality monitoring stations — six located in Makkah and the holy sites and three in Madinah.
These stations operate around the clock to measure air quality, and if any pollutant is detected, field teams are dispatched immediately to the site to identify the source and coordinate with the authorities to eliminate the cause of pollution.

East Arafat Hospital's mobile unit performs 14 emergency cardiac procedures during Hajj
MAKKAH: A mobile unit of East Arafat Hospital's Cardiology Department has successfully performed 14 emergency cardiac catheterization procedures since it began operations on the first day of Hajj, the Makkah Health Cluster has announced. The procedures are being conducted under the direct field supervision of King Abdullah Medical City based in Makkah city, the health cluster said in a statement carried by the Saudi Press Agency, or SPA. Composed of a specialized cardiology team, supported by qualified Saudi professionals in anesthesia, nursing, and urgent cardiac care, the mobile cardiac catheterization unit is deployed at the holy sites to provide immediate on-site intervention. Officials said the initiative eliminates the need to transfer patients to specialized centers, 'thereby enhancing patient safety and ensuring continuous medical care.' Meanwhile, the Air Medical Evacuation team at the Ministry of Defense rescued an Indonesian pilgrim who suffered a cardiac arrest on June 5 in Makkah. The patient was airlifted from Al Noor Hospital in Makkah to King Abdulaziz Specialist Hospital in Taif city. Air evacuation units stationed near the holy sites ensure rapid emergency response, improving rescue times and increasing survival rates. Health officials had earlier announced the successful test of a new service transporting medicine with drones during Hajj, which started June 4 and will run until June 9. As reported earlier by Arab News, Health Minister Fahad AlJalajel the drone delivery trials over the past two years tested for safe takeoff and landing, as well as high temperatures. The drones are equipped with cooling systems, he said. The drone initiative is a part of the comprehensive healthcare transformation taking place in the Kingdom, under the Saudi Vision 2030 program.

Partnerships for lasting environmental protection
Environmental challenges know no borders. From rising temperatures to biodiversity loss, these issues demand collective action. In Saudi Arabia, we are responding to this global call through a model grounded in partnership, collaborating with international organizations, scientific institutions and private innovators to deliver lasting environmental protection. Under Vision 2030, the Kingdom has embarked on a transformative journey to decarbonize its economy and restore its ecosystems. But what is especially powerful is how this journey is being shaped not only by local resolve but by global cooperation. Across ministries, research centers and giga-projects, Saudi Arabia is partnering with the world to deliver outcomes that serve both people and planet. At the heart of Saudi Arabia's environmental agenda is the Saudi Green Initiative — a program aiming to plant 10 billion trees, rehabilitate 40 million hectares of degraded land, and reduce carbon emissions by more than 278 million tonnes per year. SGI has aligned with global partners such as the UN Environment Programme, UNFCCC and the World Economic Forum's platform, helping to situate the Kingdom's afforestation and restoration efforts within a broader planetary framework. Agricultural resilience is also receiving international support. The Ministry of Environment, Water and Agriculture works closely with the Food and Agriculture Organization of the UN on sustainable aquaculture and dryland farming. Through its participation in the Global Soil Partnership, Saudi Arabia is contributing to global knowledge on soil health in arid regions — a vital issue for food security in a warming world. Progress would be impossible without science. The King Abdullah University of Science and Technology has emerged as a world-class partner in marine science, working with multiple entities to inform data-driven conservation. Their work with the Kingdom's smart city, NEOM, for example, includes coral reef restoration and coastal habitat mapping powered by advanced robotics and AI. On the wildlife front, the National Center for Wildlife is collaborating with the International Union for Conservation of Nature and CITES to safeguard native species. From Arabian oryx reintroductions to hawksbill turtle protection, these programs are helping to rebuild the Kingdom's ecological heritage. Similarly, the National Center for Vegetation Cover and Combating Desertification has been instrumental in driving desert restoration. Through its leadership role in the UN Convention to Combat Desertification, and as the host of COP16, Saudi Arabia is demonstrating how arid nations can lead in the global fight against land degradation. Its mangrove and seagrass restoration pilots are already informing policy across the region. In my role as group chief environment and sustainability officer at Red Sea Global, I've witnessed firsthand the transformative power of collaboration. Our flagship regenerative tourism destinations — The Red Sea and AMAALA — are not only redefining travel but also setting new standards for environmental stewardship. Sustainability is embedded in every stage of our projects, from development to daily operations. Whether it is through the use of renewable energy, innovative waste management systems or biodiversity conservation, our goal is to reduce our environmental footprint and ensure the long-term health of the region. Our commitment is demonstrated through continuous environmental monitoring, strong partnerships and bold sustainability targets. From government ministries to giga-projects, we are inviting the world to join us — not just as observers, but as co-creators of a greener future. Raed Albasseet We worked with KAUST to conduct the largest marine spatial planning simulation ever undertaken in Saudi Arabia, allowing us to design with precision and avoid ecological harm. We are also among the first developers in the world to have all operational resorts LEED-certified, working closely with the US Green Building Council to achieve the highest sustainability standards. Today, we hold the most LEED Platinum–certified hospitality assets of any single developer globally. Beyond our project sites, our environmental team contributes to the global knowledge base through peer-reviewed research and international conferences, including the International Association for Impact Assessment, where we have shared scientific insights on regenerative development and large-scale conservation planning. Through our partnership with The Ocean Race, we are advancing ocean literacy among Saudi youth, while positioning AMAALA as host of the Race's 2027 Grand Finale. On the infrastructure side, our multi-utilities agreement with EDF Group and Masdar enables AMAALA to be powered entirely by the sun, eliminating 350,000 tonnes of CO2 equivalent each year. And through our collaboration with the National Livestock and Fisheries Development Program, we are embedding sustainable fishing practices into the heart of our destination's food systems — protecting biodiversity while supporting local livelihoods. These efforts form only a fraction of Saudi Arabia's broader journey. But they reflect a truth I believe in deeply: When knowledge, resources and values are shared across borders, we can do more than sustain the environment — we can regenerate it. Saudi Arabia's environmental transformation is still unfolding, but the trajectory is clear. It is a story of shared responsibility. From government ministries to giga-projects, we are inviting the world to join us — not just as observers, but as co-creators of a greener future. If collaboration is the climate solution, Saudi Arabia is becoming one of its strongest conveners. And as the world looks to scale up its environmental impact, the Kingdom stands ready to collaborate, contribute and lead where it matters most. * Raed Albasseet is head of environment and sustainability at The Red Sea Development Company.
