A selection of papers presented at the international symposium on SUstainable resource MAnagement and POlicy options for rice ecosystems (SUMPOL 2005), Hangzhou, China, 11-14 May 2005.

摘要

This special section includes 9 papers from the SUMPOL 2005 symposium. At this symposium, methodologies and their applications were presented for exploring and identifying current and emerging issues in rice-based agro-ecosystems. The emphasis of both scientific approaches and illustrative case studies is on responding to the challenge to address the diverse resource use problems, the multi-scale dimensions of land use decisions and the necessity of joint learning in improved ecosystem management and policy formulation. The focus is on technology and policy options for rice ecosystems that need to cope with rapid urbanization, and the associated strong intensification and diversification of the agricultural sector in Asia, against a background of global and regional economic and technological developments.
