The cotton fields of Uzbek Shirzod Donayev are about to harvest. At least 5000 kilograms per hectare. "On the 20th, standing in an invisible cotton field, Donayev confidently predicted. Just three years ago, this was an unimaginable harvest. Since the use of Chinese cotton seeds and technology, his cotton field production has steadily increased, almost double the past, while inputs such as manpower, fertilizer, and water have decreased by more than half. In 2020, Donayev began to accept the guidance of experts from the Xinjiang Institute of Ecology and Geography of the Chinese Academy of Sciences (hereinafter referred to as the "Xinjiang Institute of Biological Sciences"), and became the first person in his village of Guwarak to try China's water-saving cotton planting technology. In the past three years, his life has undergone tremendous changes, not only renovating his house, but also buying a new car, resulting in a significant increase in family income. For Donaev, although income growth is important, he values future development prospects more. Uzbekistan is rich in cotton and is known as the "Platinum Country". However, the livelihoods of countless cotton farmers in Uzbekistan are facing serious threats from the Aral Sea ecological crisis. The Aral Sea, located at the border between Uzbekistan and Kazakhstan, was once the fourth largest lake in the world. Comparing satellite photos, it can be seen that the shrinking area of the Aral Sea is shocking. From 1960 to 2020, the surface area of the Aral Sea decreased from approximately 67000 square kilometers to approximately 6000 square kilometers. After nearly 5 years of joint scientific investigation, scientists from China and Uzbekistan jointly released a phased research report at the end of 2022, stating that the increase in evapotranspiration caused by rising temperatures is a key factor in the sharp reduction of the Aral Sea area, and proposing a governance plan to promote efficient water-saving technology to restore the Aral Sea ecology. Chen Xi, director of the Central Asia Ecological and Environmental Research Center of the Chinese Academy of Sciences, pointed out that water-saving technology is one of the important ways to solve the ecological difficulties of Central Asian countries. A large amount of water resources in Uzbekistan are used for cotton planting, and the problem of large water consumption can be effectively solved by promoting water-saving technology to improve water efficiency. China's water-saving technology is already very mature. In the cotton producing areas of Xinjiang, the drip irrigation technology under plastic film has been popularized for many years. In a cotton field not far from Urumqi, cotton farmer Gong Lunquan reminisced while waving his hands to demonstrate the practice of "flooding" in the past. Previously, a large amount of irrigation was required every spring and winter, which had high requirements for ground smoothness. It was not easy for seedlings to emerge in higher and lower areas. "He said that using drip irrigation under film technology saved at least 500 cubic meters of water per acre of land per year. As early as 2019, the Xinjiang Institute of Soil and Water Resources and the Water Research Institute of the Ministry of Water Resources of Uzbekistan signed an agreement to jointly build a water-saving cotton field demonstration zone. In the same year, the institute signed an agreement on the ecological governance of the Aral Sea with the Uzbekistan Aral Sea International Innovation Center. At present, Xinjiang Institute of Science and Technology has established a batch of water-saving cotton field demonstration zones in Uzbekistan, and is preparing to further expand its scale in the future. Donayev's cotton fields are located in these demonstration areas. The local cotton yield, which used to be over 2000 kilograms per hectare, has now exceeded 4500 kilograms. This successful experience has attracted increasing attention, and many people have traveled specifically from other places to arrive in Uzbekistan
