Abstract

Recent studies highlighted the multiple positive and negative contributions of livestock to society. Livestock production, through its direct and indirect impacts on land use, is an important driver of services provision. Although a few studies provide an account on the multiple services in different livestock systems, there is still an important knowledge gap on the drivers that contribute to the differentiation of services provisioning across areas. We investigated the hypothesis that the current level of services has derived from past intensification trajectories of livestock. The objective of this study was to understand the influences of past changes in livestock, land-use and socio-economic variables on the current provision of social, environmental and cultural services by the livestock sector in France. We combined a long-term country-wide database on livestock intensification between 1938 and 2010 and a database on services provisioning in 2010. We used a set of multivariate methods to simultaneously analyse the changes in livestock intensification from 1938 to 2010 and the current level of services provisioning. Our analysis focused on a set of 60 French departments where livestock play a significant economic role in agricultural production. Our study revealed that the provision of services was spatially structured and based on three groups of departments, characterised by different rates of change in intensification variables. In the first group, 'Intensive livestock areas', the high level of employment in the livestock sector was mainly associated with high rates of change in monogastric stocking rates (+1045%) and milk productivity (+451%). In the second group, 'Extensive livestock areas', the high levels of environmental and cultural services were mainly associated with moderate rates of change in herbivores stocking rate (+95%) and the stability of grassland area (+13%). In the third group, 'Transition areas', the low provision of all services was associated with the decline in livestock due to crop expansion. This study provides knowledge to understand how past changes determined the current contribution of livestock areas in providing differentiated bundles of services, which might help steer the development of the current livestock sector towards more sustainable trajectories.

摘要

最近的研究强调了畜牧业对社会的多重积极和消极贡献。畜牧业生产通过其对土地利用的直接和间接影响,是提供服务的重要驱动力。尽管一些研究提供了不同畜牧业系统中多种服务的说明,但对于导致不同地区服务提供差异的驱动因素仍存在重要的知识差距。我们假设,当前服务水平源自畜牧业过去的强化轨迹。本研究的目的是了解过去畜牧业、土地利用和社会经济变量的变化如何影响法国畜牧业目前提供的社会、环境和文化服务。我们结合了 1938 年至 2010 年期间畜牧业强化的全国性长期数据库和 2010 年服务提供的数据库。我们使用了一套多变量方法,同时分析了 1938 年至 2010 年期间畜牧业强化的变化和当前服务提供水平。我们的分析集中在法国 60 个部门,这些部门的畜牧业在农业生产中发挥着重要的经济作用。我们的研究表明,服务的提供具有空间结构,并基于三个部门组,其特征是强化变量的变化率不同。在第一组“集约化畜牧业地区”中,畜牧业部门的高就业率主要与单胃动物存栏率(+1045%)和牛奶生产力(+451%)的高变化率有关。在第二组“粗放畜牧业地区”中,环境和文化服务的高水平主要与草食动物存栏率(+95%)和草地面积(+13%)的适度变化率有关。在第三组“过渡地区”中,所有服务的低提供都与由于作物扩张而导致的畜牧业下降有关。这项研究提供了知识,以了解过去的变化如何决定当前畜牧业地区提供差异化服务的组合,这可能有助于引导当前畜牧业部门朝着更可持续的轨迹发展。
