Great Green Wall in China -- I'm sharing a video titled "How China turned the desert into green forests" with an impressive story about ecosystems transformation with a large-scale master-planned forestation over vast desert lands to combat desertification in China. I've learned a bit more everytime when I read info about this "Great Green Wall" project, and hope you'll enjoy this one. I'm spreading it as part of my actions to take part in the UN World Soil Day 2025. The link goes: https://www.msn.com/en-us/news/world/how-china-turned-the-desert-into-g…

SKYWARN actions kickoff on Skywarn Recognition Day 2025
Today, December 6, is the SKYWARN Recognition Day (SRD) in the US. While the NOAA’s National Weather Service (NWS) cancelled the SRD 2025, as a registered Official Skywarn Spotter and a SciStarter participant in the SKYWARN citizen science project stationed at the Arcadia Ecohome in the foothill community of Arcadia, California, I'm taking on a weeklong voluntarily sky-watch of the San Gabriel Mountains, a desert mountain range just north of Arcadia, as part of my actions to take part in the celebrations of both the 2025 SRD on December 6, the first Saturday of December, and International Mountain Day on December 11, along with reporting and advocacy activities such as this writeup. Monitoring the sky over desert mountains in Southern California where unusual winter wildfires have occurred in recent years, such as the devastating ones in January 2025, driven by extreme drought and heat after wet years and strong Santa Ana winds, is becoming critical in the era of climate new normal with hazardous windstorms and firestorms for our attentions and actions as members of the Skywarn Weather Spotters Network and the Fire Adapted Communities Network (FAC Net).

Soil properties and soil biodiversity play significant roles in land degradation, especially in arid regions. Today is the UN World Soil Day (WSD) 2025 themed "Healthy Soils for Healthy Cities”. As an urban farmer and a USEPA recognized Qualify Water Efficient Landscaper (QWEL) working at the Arcadia Ecohome’s micro-agroforest, a Certified Bee Friendly Farm and a listed Climate Victory Garden, located in the arid Southern California, I’ve registered a local event with FAO to support the global celebrations of WSD. Our key actions taken today is focused on improving soil properties and biodiversity to combat land degradation with actions to add organic matters from fallen leaves, tree trimmings & food wastes to the forest floor through composting so as to enhance the soil sponge’s functions of taking and keeping moisture from cool night dews, to harbor a bio-diversified forest-floor inhabitants such as insects, earthworms & microbes who contribute to build healthy soils, to induce root growth for reducing soil erosion, and to minimize green & food wastes generated in urban areas to be hauled to remote desert landfills. The photo taken today (sorry, cannot be uploaded) shows sheet composting of fallen leaves all over the forest floor, pile composting of twigs & branches by tree roots and an in-ground composting of kitchen wastes, all for building healthy soils by nature-based solutions. I’m sharing what we do at CIEDM with our networks, especially my follow members in the United Nations Convention to Combat Desertification (UNCCD) Communities of Learning and Practice, as part of our grassroots actions in social media campaign for WSD.

Thanks for Suyu's warm welcome! As a new member of this community, I'm delighted to briefly introduce myself: I'm an academic and practitioner in the field of urban and environmental planning, with an interest in nature/resources/water conservation. I've lived and worked for 40+ years in the Los Angeles metropolitan area, a part of the arid US Southwest region, and on daily basis encountered/crossed challenges and news about drought, heatwaves, wildfires, flash floods and other climate issues in this region and beyond. With my Chinese ethnic origin, growup in Taiwan, and work & travel experiences in several parts of Asian, including serving as a faculty member in Saudi Arabia and China, I'm glad to be here to share and learn with all of you in this community.

New insights on declining natural carbon sinks

A new study published in Nature highlights how climate change and land-use pressures are reducing the Earth’s ability to absorb CO₂. The findings show that natural land sinks are weakening, while tropical forests in Southeast Asia and South America are shifting from carbon sinks to carbon sources, a trend driven by warming, drought, and deforestation.

Understanding these changes is essential for effective climate and drought management strategies.

Join the conversation and explore how stronger land stewardship and climate-resilient practices can support global mitigation efforts.

This is an interesting article. Some people have the instinct that Pacific islands should have enough water due to their location (central in the ocean), but actually they also suffer from drought. This suggests that drought is indeed global and can affect all countries.

Drought Monitoring to Build Climate Resilience in Pacific Island Countries

Abstract: Drought is a complex and impactful natural hazard, with sometimes catastrophic impacts on small or subsistence agriculture and water security. In Pacific Island countries, there lacks an agreed approach for monitoring agricultural drought hazard with satellite-derived remote sensing data. This study addresses this gap through a framework for agricultural drought monitoring in the Pacific using freely available space-based observations. Applying World Meteorological Organization’s (WMO) recommendations and a set of objective selection criteria, three remotely sensed drought indicators were chosen and combined using fuzzy logic to form a composite drought hazard index: the Standardised Precipitation Index, Soil Water Index, and Normalised Difference Vegetation Index. Each indicator represents a subsequential flow-on effect of drought on agriculture. The index classes geographic areas as low, medium, high, or very high levels of drought hazard. To test the drought hazard index, two case studies for drought in the western Pacific, Papua New Guinea (PNG), and Vanuatu, are assessed for the 2015–2016 El Niño-related drought. Findings showed that at the height of the drought in October 2015, 58% of PNG and 72% of Vanuatu showed very high drought hazard, compared to 6% and 40%, respectively, at the beginning of the drought. The hazard levels calculated were consistent with conditions observed and events that were reported during the emergency drought period. Application of this framework to operational drought monitoring will promote adaptive capacity and improve resilience to future droughts for Pacific communities.

Hello Everyone,

I am Debashis Roy, and I am delighted to join this vibrant community of researchers, policymakers, and practitioners working toward sustainable drought management in Asia. My research focuses on social–ecological systems (SES) modelling, particularly exploring the drought–food insecurity nexus. I am deeply interested in understanding how climate, ecosystems, and human systems interact under drought stress and how this knowledge can inform sustainable and equitable solutions.

I look forward to collaborating with fellow researchers, policymakers, and development practitioners to advance our shared goal of strengthening resilience to drought and enhancing food security across the region.

Warm regards,
Debashis Roy
