Asia Development Bank, Tourism Sector Strategy 2016 – 2025, 2017 Emerging 2 Challenges - Rapid growth, changing demographics and urbanization Over the past 30 years, the economy of the Mekong subregion has expanded greatly, with the annual GDP increases of the riparian countries ranging between approximately 5 and 9.5 percent. The subregion is also experiencing rapid urbanization. Vientiane’s population nearly quadrupled between 2008 and 2017, and more than 50 percent of the estimated 293 million people living in Yunnan, China and the lower Mekong countries could reside in urban areas by 2050.

- Competing interests and cumulative impacts of development As populations and economies grow, water and natural resources are under increasing and often competing demands. The development activities in the Region have led to significant environmental challenges. Cumulative impacts of development on water and other natural resources, the economy and society put the long-term sustainability of the Mekong Region at risk.

- Increasing uncertainty due to The Mekong River Basin is especially exposed to climate change impacts, with recent studies indicating an expected increase in temperature of 0.79 degrees Celsius by 2030 and an increase in annual precipitation of over 15 percent. Flood and drought risks are increasing and affecting the livelihoods of millions of people in the Mekong River Basin. Water levels were recorded at their lowest ever in mid-2019, while heavy monsoon rains in 2018 led to the displacement of 6,600 families in Lao PDR.

- A growing number of cooperation frameworks There are more than thirteen regional cooperation frameworks that provide a strong foundation for regional coordination and cooperation. However, existing coordination principles have not been consistently followed by riparian states and coordination fora face multiple difficulties in aligning states’ different interests and activities. Objectives of The World Bank Group (WBG) has a long history of regional engagement and is heavily invested in the Mekong River Basin. Starting in 1998 with funding from the Global Environment Facility, the Water Utilization Program (WUP) supported the establishment of the Mekong River Commission Mekong Vision 3.0 (MRC). In 2008, a follow-on Mekong Integrated Water Resources Management (M-IWRM) Program was developed, including further support to MRC coupled with three national water resources management projects in Cambodia, , and Vietnam. In total, the WBG currently has roughly 3 100 on-going activities and an investment portfolio amounting to about US$12 billion at the national level. As the M-IWRM program comes to completion in 2021, the Mekong Vison 3.0 represents the next World Bank regional engagement. Drawing on the WBG’s multi-disciplinary, transboundary waters expertise and in partnership with all riparian countries and other key stakeholders, Mekong Vison 3.0 aims to catalyze shared understanding for better resource utilization and set forth new directions for regional cooperation.

Building on the key pillars of the recently concluded WBG-UN High Level Panel on Water, the Mekong Vision Stocktaking and an analysis of the prevailing Phase 3.0 is organized around “understanding, valuing, and geo- and hydro-political economy of the Mekong 1 managing the Mekong” and includes three phases. subregion.
