Developing effective policies for the sustainable development of ecological agriculture in China: the case study of Jinshan County with a systems dynamics model

This paper focuses on a search for concrete policy measures to facilitate the overall sustainability of ecological agricultural development at a county level. For this purpose, a system dynamics model (AISEEM) has been developed to explore the potential long-term ecological, economic, institutional and social interactions of ecological agricultural development through a case study of Jinshan County in China. The model provides an experimental platform for the simulation and analysis of alternative policy scenarios. The results indicate that the diversification of land-use patterns, government low interest loans and government support for training are important policy measures for promoting the sustainable development of ecological agriculture, at least in the case study context. In addition, the study reveals that environmentally sound technology (e.g., biogas project) alone cannot sufficiently induce farmers to adopt ecological agricultural practices. Limited availability of information, risk aversion and high transaction costs are major barriers to the adoption of alternative agricultural practices. In this regard, the importance of capacity building and institutional arrangements are emphasised through the development of an improved policy-making process on agricultural sustainability. This case study highlights the importance of combining the ecological economics analytical framework with the system dynamics modelling approach as a feasible integrated tool to provide insight into the policy analysis of ecological agriculture, and thus set a solid basis for effective policy making to facilitate its sustainable development on a regional scale.
