Rural areas around the world are declining as people move to cities for better opportunities, leading to population loss, economic hardship, and social issues. In China, over 170 million peasant workers left rural areas between 1990 and 2014, causing a significant decline in rural communities. Rural areas face challenges such as poor land management, lack of infrastructure, and limited access to education and healthcare. The consequences are severe, including the closure of schools, increased suicide rates, and the decline of local economies. Rural decline is a global issue, with rural areas in the US, Sweden, and sub-Saharan Africa also experiencing population loss. Cities receive more investment and resources, exacerbating the imbalance. However, some countries have implemented policies to support rural development, such as land redistribution in Taiwan and South Korea, and investments in public health and education in Malaysia, the Philippines, and Thailand. To reverse rural decline, governments need to promote ruralization alongside urbanization, ensuring equal access to resources and services. Local governments should develop strategies to attract businesses, offering tax concessions and low land prices. Bottom-up initiatives are essential, encouraging local stakeholders to work together. Some villages may need to be relocated, but this should be done with the consent of the residents. A scientific plan is needed to guide rural revitalization, involving multidisciplinary research and the use of big-data analysis. The United Nations should prioritize rural development, ensuring it is given as much importance as poverty alleviation, climate change, and peace. Both cities and villages must be developed sustainably to support each other. Researchers must understand the forces driving rural decline and develop effective strategies to improve rural livelihoods.Rural areas around the world are declining as people move to cities for better opportunities, leading to population loss, economic hardship, and social issues.
