Summary
China
Area of Science:
- Agricultural Economics
- Food Security Studies
- Data Science
Background:
- China's crucial role in global food security is challenged by new development patterns.
- Existing grain statistics are fragmented, hindering comprehensive food security assessments.
Purpose of the Study:
- To construct a comprehensive dataset for assessing China's food security.
- To provide robust data for policy-making and academic research.
Main Methods:
- Developed the time-series China Food Security Comprehensive Assessment Dataset (CFSAD).
- Dataset covers grain, rice, wheat, maize, and soybeans.
- Incorporates five dimensions: basic guarantee, market operations, scientific/technological capacity, resource/environmental conditions, and purchasing power, with fourteen indicators.
Main Results:
- The CFSAD offers a more scientific and holistic view of China's food security.
- The dataset integrates diverse indicators across multiple dimensions for a comprehensive analysis.
Conclusions:
- The CFSAD provides essential data support for effective government policy-making.
- Facilitates advanced academic research on China's food security challenges and solutions.

Throughout its ~4.5 billion year history, the Earth has experienced periods of warming and cooling. However, the current drastic increase in global temperatures is well outside of the Earth’s cyclic norms, and evidence for human-caused global climate change is compelling. Paleoclimatology, the study of ancient climate conditions, provides ample evidence for human-caused global climate change by comparing recent conditions with those in the past.
