Abstract

Viticulture is an example of a socio-ecological system that poses serious challenges for sustainable soil management and pesticide use, with various interactions between winegrowers’ decision-making and ecological consequences. This study introduces an agent-based model (ABM) on winegrowers’ decision on inter-row management and pesticide use. The ABM builds upon an empirical study of winegrowers’ decision-making in European viticultural landscapes and has been built for three case study regions: Leithaberg (Austria), Palatinate (Germany) and Târnave (Romania). The ABM allows for analysing potential effects of policy instruments including mandatory vegetation cover in the inter-rows, the reduction of fungicide use and ban of insecticides against Lobesia botrana. The effects of policies differ between the case study regions, indicating how important the local context is for effective policies. For example, policies aiming at higher inter-row vegetation cover had the strongest effects on vegetation cover, landscape aesthetics and soil loss in Târnave since many vineyards are currently intensively tilled and there exist no policies supporting inter-row vegetation cover in Romania.

探索气候变化和政策情景下葡萄种植者的行为和生态影响——以欧洲三个葡萄种植区为例

摘要

葡萄栽培是社会生态系统的一个例子，它对可持续土壤管理和农药使用提出了严峻的挑战，葡萄种植者的决策和生态后果之间存在各种相互作用。本研究引入了一种基于代理的模型（ABM），用于葡萄种植者行间管理和农药使用的决策。ABM 基于对欧洲葡萄栽培景观中葡萄种植者决策的实证研究，并针对三个案例研究地区建立：莱塔伯格（奥地利）、普法尔茨（德国）和塔尔纳夫（罗马尼亚）。ABM 允许分析政策工具的潜在影响，包括行间的强制植被覆盖、减少杀菌剂的使用以及禁止针对Lobesia botrana的杀虫剂。案例研究区域之间的政策效果有所不同，这表明当地环境对于有效政策的重要性。例如，旨在提高行间植被覆盖的政策对塔尔纳夫的植被覆盖、景观美感和土壤流失影响最大，因为许多葡萄园目前采用集约化耕作，而且罗马尼亚没有支持行间植被覆盖的政策。
