On August 17th, the 17th Conference of the Parties to the United Nations Convention to Combat Desertification (UNCTAD COP17) officially kicked off in Ulaanbaatar, the capital of Mongolia. During the conference, Longi Green Energy participated in multiple side events and systematically explained the enormous potential of photovoltaic technology in enhancing the resilience of global food supply. At the same time, Longi officially released a solution for photovoltaic assistance in food security.
At the "From Desert to Assets - Integrated Photovoltaic Ecological Restoration Comprehensive Solution" side event jointly organized by the School of Social Sciences at Tsinghua University and the China Green Development Foundation, Li Zhenguo, founder and chief technology officer of LONGi Green Energy, attended the conference via video link and pointed out that traditional food production is highly dependent on natural photosynthesis and climate conditions. Extreme weather events such as droughts and floods have had a strong impact on agricultural production, and global climate change is putting unprecedented pressure on the already fragile food supply system. As costs decrease, photovoltaic technology not only reduces carbon emissions, but also has the potential to provide new solutions for enhancing the resilience of global food supply.
Li Zhenguo recently published a forward-looking perspective article titled "Photovoltaics for Food Security" in the top international academic journal Nature Sustainability, which systematically elaborates on two technological paths with practical application prospects.
8月17日，《联合国防治荒漠化公约》第十七次缔约方大会（UNCCD COP17）在蒙古国首都乌兰巴托正式拉开帷幕。大会期间，隆基绿能参与多场边会活动，系统阐述了光伏技术在提升全球粮食供应韧性方面的巨大潜力，同时隆基正式发布了光伏助力粮食安全的解决方案。
在由清华大学社会科学学院与中国绿色发展基金会联合主办的“从荒漠到资产——光伏一体化生态修复综合解决方案”边会上，隆基绿能创始人、首席技术官李振国通过视频连线参会并指出，传统粮食生产高度依赖自然光合作用与气候条件，干旱、洪涝等极端天气对农业生产造成了强大冲击，全球气候变化正在让本就脆弱的粮食供应体系面临前所未有的压力。而随着成本的降低，光伏技术不仅能降低碳排放，更有望为提升全球粮食供应韧性提供全新的解决方案。
李振国近期在国际顶级学术期刊《自然·可持续发展》（Nature Sustainability）上发表的前瞻性观点文章《光伏技术助力粮食安全》（Photovoltaics for food security），系统阐述了两条具有现实应用前景的技术路径。
The first path: Photovoltaic driven carbon dioxide artificial synthesis of starch. Using photovoltaic power generation to electrolyze water to produce green hydrogen, coupling it with captured carbon dioxide to synthesize green methanol, which is then converted into starch through processes such as oxidation and polymerization. Compared to traditional natural photosynthesis, which has a solar energy utilization efficiency of about 2%, this pathway can increase efficiency to 7% to 10%. Calculations show that if only 3.7% of the Sahara Desert is used to deploy photovoltaics, 26 trillion kilowatt hours of green electricity can be generated, which is enough to synthesize 3 billion tons of food and meet the food needs of the current global population.
The second path: a photovoltaic driven "energy water food" collaborative system. By constructing photovoltaic power stations in desert areas and utilizing the shading effect of photovoltaic modules to reduce soil moisture evaporation, improve soil microclimate, and reduce irrigation demand. By combining photovoltaic driven seawater desalination with cross regional water transfer projects, desert land that was originally unsuitable for cultivation can be gradually transformed into cultivable farmland.
In fact, Longi has been actively exploring in the Kubuqi Desert of Inner Mongolia, China - through on-board power generation, off board planting, and inter board aquaculture. Under the photovoltaic panels, the once barren land is now revitalized. This practice has verified the feasibility of the integrated development of "photovoltaic+ecology+agriculture", providing a replicable Chinese solution for the coordinated development of ecological restoration and food production in desertification areas.
第一条路径：光伏驱动的二氧化碳人工合成淀粉。利用光伏发电进行电解水制取绿氢，将其与捕集的二氧化碳耦合，合成绿色甲醇，进而通过氧化、聚合等过程转化为淀粉。相较于传统自然光合作用约2%的太阳能利用效率，这条路径可将效率提升至7%到10%。测算显示，若仅利用撒哈拉沙漠3.7%的面积部署光伏，即可产生26万亿千瓦时的绿电，足以合成30亿吨粮食，满足当前全球人口的粮食需求。
第二条路径：光伏驱动的“能源-水-食物”协同系统。通过在荒漠地区建设光伏电站，利用光伏组件的遮荫效应减少土壤水分蒸发，改善土壤微气候、降低灌溉需求。结合光伏驱动的海水淡化与跨区域输水工程，可将原本不宜耕种的荒漠土地逐步改造为可耕作农田。
事实上，隆基已在中国内蒙古库布齐沙漠展开积极探索——板上发电、板下种植、板间养殖。光伏板下，曾经的不毛之地正在焕发生机。这一实践验证了“光伏+生态+农业”融合发展的可行性，为荒漠化地区的生态修复与粮食生产协同发展提供了可复制的中国方案。
The theme of this COP17 conference is "Restoring Land, Igniting Hope". Longi actively participates in multiple side events and has in-depth exchanges with government agencies, scientists, and business representatives from around the world, sharing China's experience in the deep integration of photovoltaics with desertification control and ecological restoration.
From cutting-edge exploration in the laboratory to practical verification in the desert, photovoltaics is moving from an energy solution to the cornerstone of sustainable development. In the future, Longi will actively respond to climate change with solar energy storage technology, continue to promote the deep integration of photovoltaics with ecology, agriculture, water resources and other fields, build a more resilient global sustainable development system, and truly benefit everyone with more economical, safer and convenient green energy.
本届COP17大会主题为“恢复土地，重燃希望”。隆基积极参与多场边会活动，与来自全球的政府机构、科学家、企业代表深入交流，分享光伏与荒漠化治理、生态修复深度融合的中国经验。
从实验室的前沿探索到荒漠中的实践验证，光伏正在从能源解决方案走向可持续发展的基石。未来，隆基将以光储科技积极应对气候变化，持续推动光伏与生态、农业、水资源等领域的深度融合，构建更具韧性的全球可持续发展体系，让更经济、更安全、更便捷的绿色能源真正惠及每一个人。
