Global scientists have selected the top 10 scientific issues critical to human society development for 2022, the China Science Daily reported on Tuesday.

Focusing on the United Nations 2030 Agenda for Sustainable Development, this year's top 10 challenges mainly relate to climate, cities and manufacturing.

The issues include coping with extreme weather and climate events, building a green and efficient recycling system of urban waste resources, and realizing a transition from resource-intensive and high-carbon manufacturing industries to decentralized and low-carbon ones.

These issues were proposed by chief editors, editorial board members and strategic scientists of well-known sci-tech journals. Scientists from more than 10 countries and regions, including China, the U.S. and Britain, participated.

"Selecting and publishing the top 10 issues will help pool wisdom, build solution consensus, and deepen the openness, trust and cooperation of the global sci-tech community," said Luo Xian'gang, an academic at the Chinese Academy of Engineering.

Luo announced the list at the 4th World Science and Technology Development Forum in Chengdu, the capital of southwest China's Sichuan Province.

Themed "Openness, Trust and Cooperation," the forum has attracted more than 300 scholars, representatives from international organizations and entrepreneurs. Among them are seven Nobel laureates and over 60 academicians from China and abroad.

The event is jointly hosted by the China Association for Science and Technology, the Chinese Academy of Sciences, the Chinese Academy of Engineering, and the Sichuan provincial government.
