Heterogeneity in practice adoption to reduce water quality impacts from sugarcane production in Queensland
研究了昆士兰蔗农采纳最佳管理实践（BMP）的异质性，发现不同实践和农户群体的采纳驱动因素不同，为设计针对性政策提供依据。
A key strategy in reducing water quality impacts into the Great Barrier Reef is to change farm management practices to limit the creation of pollutants or their transmission off farm. However, designing programs to improve adoption in agriculture of Better Management Practices (BMPs) can be challenging because of heterogeneity among landholders and between farms and farming systems. This is relevant to broader issues in the adoption literature where a focus on identifying factors influencing and heterogeneity in adoption have rarely transferred through to analysis and prediction models suitable for policy purposes. In this case study these issues have been tested with sugarcane farmers in Queensland, where the current policy settings are targeting increases in adoption of better management practices from 34% in 2011 to 90% by 2018. The main goals of the study were to identify how rates of adoption for different practices might be explained by (a) the motivations of farmers (b) potential barriers to adoption (c) farm characteristics and (d) financial drivers. The results confirm that measures to improve BMP adoption are complicated by heterogeneity in adoption drivers between practices and across groups of landholders, creating challenges to find effective strategies to encourage adoption. © 2017 The Authors
