Core Viewpoint - The "Yin Da Ji Min" project, the largest water diversion project in Sichuan's history, has officially commenced construction to address the water scarcity issue in the Chengdu Plain by connecting the Dadu River and the Min River, creating a dual water source [1][2]. Group 1: Project Overview - The project has a total construction period of 8 years, with the water intake point located 3.5 kilometers upstream of the Luding Hydropower Station on the Dadu River [1]. - It consists of a main line and two branch lines, extending over 260 kilometers through tunnels and pipelines to deliver water to two junction points located over 100 kilometers and 40 kilometers from the Dujiangyan water conservancy hub [1]. - By 2040, the project is expected to divert 1.389 billion cubic meters of water to the Chengdu Plain, increasing to 1.523 billion cubic meters by 2050 [1]. Group 2: Impact on Water Supply - The project aims to primarily support urban and industrial water supply while also considering agricultural irrigation, potentially benefiting 34.13 million people across 43 counties in the Chengdu Plain economic zone [1]. - The water supply guarantee rate for urban and industrial use is projected to increase from 90% to 97%, while the agricultural irrigation guarantee rate is expected to reach 80% [2]. - The project will enhance the spatial and temporal distribution of water resources in Sichuan, ensuring water security for the Chengdu Plain economic area and supporting high-quality economic and social development in the province [2].

Core Viewpoint - The expansion of the Dujiangyan irrigation area to 11.647 million acres is a significant milestone, but it raises concerns about water resource sustainability due to climate change and human activities affecting the Min River's upstream runoff [1][2][5][7]. Group 1: Irrigation Area Expansion - The Dujiangyan irrigation area will reach 11.647 million acres in 2023, covering 41 counties across 8 cities and benefiting 30 million people [2][4]. - Historically, the irrigation area has expanded from approximately 700,000 acres in the Han Dynasty to over 11 million acres in recent years, with significant growth during the 1950s to 1970s [3][4]. - The irrigation area is projected to further increase to 15.19 million acres in the future, indicating ongoing development [7]. Group 2: Water Resource Challenges - The Min River's upstream runoff has significantly decreased over the past decades, with annual average runoff dropping from 174 billion cubic meters in the 1930s to 132.6 billion cubic meters in the 1990s [6][7]. - The Dujiangyan irrigation area currently relies on 70% of the Min River's water, leading to concerns about over-extraction and potential water shortages [5][7]. - The annual water supply for the irrigation area is projected to face a shortfall of 2.5 billion cubic meters by 2035 due to increasing demand from agriculture, domestic use, and industry [8][10]. Group 3: Solutions for Water Resource Management - The strategy to address water shortages includes both conservation measures and sourcing additional water [9][10]. - Conservation efforts have improved water-saving capabilities by 534 million cubic meters annually, earning the designation of a "water-saving demonstration irrigation area" [10]. - The "Yin Da Ji Min" project aims to divert water from the Dadu River to supplement the Min River, with projected water diversion volumes of 1.539 billion cubic meters by 2035 and 1.809 billion cubic meters by 2050 [11].
