A comprehensive review of constraints to improved management of fertilizers in China...

Highlights

• Causes of inefficient fertilizer use in China are complex.
• Influencing factors span from national politics to farm household behaviour.
• A mitigation framework for DWPA must encompass a range of measures.
• Measures include policy, supply chain modernisation, and producer incentives.
• Also enhanced extension, social security and broad engagement of civil society.

Abstract

Complex and inter-related factors explain the excessive use of fertilizer observed in many intensive farming systems in China, and hence act as barriers to development of a comprehensive policy and intervention framework for mitigation of diffuse water pollution from agriculture (DWPA). This review provides an original and contemporary synthesis of these factors that is broader, deeper and more inter-related than existing assessments. The analysis confirms that DWPA cannot be addressed by single regulatory or policy measures. There is a need to develop a mitigation framework that encompasses central policy directives, reform in governance at local level, an enabling regulatory environment, horizontal and vertical coordination in food supply chains, unbiased incentives for efficient fertilizer use and protection of water resources, enhanced agricultural, food safety and environmental education for farmers and consumers, and engagement of multiple actors beyond government.
