摘要

摘要:肉牛养殖是巴西潘塔纳尔地区的主要经济活动,在自然环境中广泛开展,在空间和时间上都是动态的。不断监测、评估和改进业绩是寻求肉牛牧场可持续利用自然资源的关键方面,因为这些牧场是潘塔纳尔的管理单位。本文提出了一种数据包络分析(DEA)方法,以潘塔纳尔湿地14个肉牛牧场为例,从财务、生产和环境可持续性三个维度对其绩效进行评估。我们分别对每个维度建模,并计算总体性能得分。我们还拟合分数回归模型来研究潜在协变量对绩效分数的影响。这里提出的方法方法被证明是适合案例研究的,因为结果符合决策者对牧场业绩的期望。综合性能分析受优质原生牧草资源比例的影响,这取决于景观的动态和时空变化。因此,整体绩效需要基于多样性保护的牧场适应性管理,这有利于产品和服务的多功能性。

Multidimensional performance assessment of a sample of beef cattle ranches in the Pantanal from a data envelopment analysis perspective
ABSTRACT: Beef cattle ranching is the main economic activity in the Brazilian Pantanal, undertaken in an extensive manner, mostly in natural environments and dynamic in space and time. The ongoing monitoring, assessment, and performance improvement are key aspects of the search for sustainable use of natural resources in beef cattle ranches, as these ranches are the management units in the Pantanal. In this paper we proposed a data envelopment analysis (DEA) approach to assess the performance of fourteen beef cattle ranches in the Pantanal wetland as a case study, considering financial, productive, and environmental sustainability dimensions. We modeled each dimension separately and calculated an overall performance score. We also fit fractional regression models to study the influence of potential covariates on the performance scores. The methodological approach proposed here proved to be adequate for the case study, as the results are in line with the expectations of decision-makers regarding the performance of the ranches. The overall performance analysis was influenced by the proportion of higher quality native forage resources, which depends on the dynamics and on the spatial-temporal variation of the landscapes. Therefore, overall performance requires adaptive management of ranches based on diversity conservation, which benefits the multifunctionality of products and services.

期刊介绍: The purpose of Ciência Rural is to publish the results of original research, note and reviews which contribute significantly to knowledge in Agricultural Sciences. Preference will be given to original articles that develop news concepts or experimental approaches and are not merely repositories of scientific data. The decison of acceptance for publication lies with the Editors and is based on the recommendations of Editorial Comission, Area Committee and/ or ad hoc reviewers. The editors and reviewers are external to the institution.
