Abstract

The current trend of biodiversity deterioration in rural systems is a complex issue that operates across multiple spatial scales. Agroforestry practices have the potential to positively contribute towards addressing these trends by shaping the structure of agricultural landscapes and their underlying ecological functions. This study aims to test a multi-scale analytical approach to understand and account for these processes. Specifically, the study seeks to assess the contributions that agroforestry practices at the farm scale can make towards supporting biodiversity, in response to the wider-scale landscape eco-mosaic structural and functional challenges and requirements (both at the local and extra-local landscape systems). To achieve this, a series of landscape ecology analyses are conducted on an agroforestry-based rice farm located in the western Po Plain region of Northern Italy. These analyses examine various landscape structural traits (such as matrix composition, patch size, shape complexity, and diversity indices) and functional traits (including connectivity and bionomic indices), with different levels of detail for each scale of analysis. This allows for the evaluation of the current ecological status of both the extra-local and local scale landscape systems (including drivers of vulnerability and resilience) and the assessment of the farm's current contributions to biodiversity support. Based on these findings, strategic agroforestry interventions are identified at the farm scale to enhance its capacity to address the wider-scale ecological gaps. Two design scenarios are assessed, wherein functional ecological traits such as landscape diversity, connectivity, and ecological stability are improved. The results confirm the role of farm scale agroforestry management as a buffering tool, demonstrating how it contributes to the restoration of broader-scale landscape vulnerabilities. The applied approach provides cost-effective assessments of biodiversity-related ecological processes, with the accuracy of the findings dependent on the comprehensive multi-scale analysis conducted.

农林业在解决波河平原地区农业景观脆弱性方面的作用
当前农村系统中生物多样性恶化的趋势是一个跨越多个空间尺度的复杂问题。农林业实践通过塑造农业景观结构及其基本生态功能,有可能为应对这些趋势做出积极贡献。本研究旨在测试一种多尺度分析方法,以了解和解释这些过程。具体而言,本研究旨在评估农场规模的农林业实践在支持生物多样性方面可做出的贡献,以应对更大规模的景观生态马赛克结构和功能挑战及要求(包括本地和本地以外的景观系统)。为此,我们对位于意大利北部西部波河平原地区的一个以农林业为基础的水稻农场进行了一系列景观生态学分析。这些分析考察了各种景观结构特征(如基质组成、斑块大小、形状复杂性和多样性指数)和功能特征(包括连通性和仿生指数),每个分析尺度的详细程度不同。这样就可以评估本地外和本地尺度景观系统的当前生态状况(包括脆弱性和恢复力的驱动因素),并评估农场当前对生物多样性支持的贡献。根据这些发现,确定了农场规模的战略性农林干预措施,以增强其解决更大规模生态差距的能力。对两种设计方案进行了评估,其中景观多样性、连通性和生态稳定性等功能性生态特征得到了改善。结果证实了农场规模的农林业管理作为缓冲工具的作用,展示了它如何有助于恢复更大规模的景观脆弱性。应用该方法可对与生物多样性相关的生态过程进行具有成本效益的评估,评估结果的准确性取决于所进行的综合多尺度分析。

期刊介绍: Community Ecology, established by the merger of two ecological periodicals, Coenoses and Abstracta Botanica was launched in an effort to create a common global forum for community ecologists dealing with plant, animal and/or microbial communities from terrestrial, marine or freshwater systems. Main subject areas: (i) community-based ecological theory; (ii) modelling of ecological communities; (iii) community-based ecophysiology; (iv) temporal dynamics, including succession; (v) trophic interactions, including food webs and competition; (vi) spatial pattern analysis, including scaling issues; (vii) community patterns of species richness and diversity; (viii) sampling ecological communities; (ix) data analysis methods.
