An analysis of developments and challenges in nutrient management in china

Area of Science:

• Agricultural Science
• Environmental Science
• Food Systems Analysis

Background:

• China achieved food self-sufficiency for its large population using limited arable land.
• Past food production success came with significant environmental costs and high resource utilization.

Purpose of the Study:

• To review nutrient management developments in China over the last 50 years.
• To identify future nutrient management challenges and propose solutions for sustainable food production.

Main Methods:

• Analysis of nutrient management in crop and animal production.
• Review of agricultural advisory systems and their structure.
• Discussion of the entire food chain from production to consumption.

Main Results:

• Significant progress in nutrient management over 50 years.
• Current achievements are linked to high environmental impacts.
• Future challenges require integrated approaches across the food chain.

Conclusions:

• Coherent national policies and institutional structures are essential for sustainable nutrient management.
• Key actions include whole food chain nutrient management, improved animal waste management, and enhanced technology transfer.
• A shift in objectives is needed from solely food security to include resource use efficiency and environmental sustainability.
