摘要

全球农业活动，特别是养猪业，通过排放污染物，对空气和水质产生不利影响，极大地加剧了环境压力。目的研究两种情景下生猪生产的环境足迹，评估活塞减排技术（PERT）在缓解环境影响方面的有效性，并分析其应用的相关环境权衡。方法采用生命周期评估方法，在基线和PERT两种情景下，量化传统养猪从摇篮到农场门口生产1 kg活重的环境影响。农业活动的主要数据是通过现场测量获得的，污染物排放的次要数据是通过文献估计的，原材料数据是通过数据库获得的。结果与结论spert减少了16个影响类别中的10个，其中4个没有变化，2个略有增加。与基线相比，陆地富营养化、酸化和颗粒物分别减少了31.37%、28.00%和26.95%。但是，在减少排放和与资源使用有关的类别之间观察到折衷。此外，敏感性分析显示，寿命为10年的PERT比寿命为5年的PERT少消耗126.30 MJ的可再生资源和1471.65 MJ的不可再生资源，但比寿命为15年的PERT多消耗42.10 MJ的可再生资源和490.55 MJ的不可再生资源。意义本研究拓展了现有猪场排放控制研究，为提高其他畜牧业的环境可持续性提供理论见解和实践范例。

Environmental impact assessment of piston technology in mitigating emissions from pig farming: Insights for sustainable agriculture

CONTEXT

Global agricultural activities, particularly pig farming, significantly contribute to environmental pressures through the emission of pollutants, which adversely impact air and water quality.

OBJECTIVE

This study aimed to investigate the environmental footprint of swine production under two scenarios, assess the effectiveness of piston emission reduction technology (PERT) in mitigating environmental impacts, and analyze the associated environmental trade-offs of its application.

METHODS

We employed a life cycle assessment to quantify the environmental impact of conventional pig farming in producing 1 kg of live weight from cradle to farm gate under two scenarios: baseline and PERT. Primary data on agricultural activities were obtained through onsite measurements, while secondary data on pollutant emissions were estimated from the literature, and data on raw materials were obtained from databases.

RESULTS AND CONCLUSIONS

PERT reduced 10 out of 16 impact categories, with 4 unchanged and 2 slightly increased. Compared with those at baseline, terrestrial eutrophication, acidification, and particulate matter were reduced by 31.37 %, 28.00 % and 26.95 %, respectively. However, trade-offs were observed between emission reductions and resource use-related categories. Moreover, sensitivity analysis revealed that PERT with a 10-year lifespan consumed 126.30 MJ fewer renewable and 1471.65 MJ fewer nonrenewable resources than did PERT with a 5-year lifespan but 42.10 MJ more renewable and 490.55 MJ more nonrenewable resources than did PERT with a 15-year lifespan.

SIGNIFICANCE

This study expands existing research on pig farm emission control and provides both theoretical insights and practical examples for enhancing environmental sustainability in other livestock sectors.

期刊介绍： Agricultural Systems is an international journal that deals with interactions - among the components of agricultural systems, among hierarchical levels of agricultural systems, between agricultural and other land use systems, and between agricultural systems and their natural, social and economic environments. The scope includes the development and application of systems analysis methodologies in the following areas: Systems approaches in the sustainable intensification of agriculture; pathways for sustainable intensification; crop-livestock integration; farm-level resource allocation; quantification of benefits and trade-offs at farm to landscape levels; integrative, participatory and dynamic modelling approaches for qualitative and quantitative assessments of agricultural systems and decision making; The interactions between agricultural and non-agricultural landscapes; the multiple services of agricultural systems; food security and the environment; Global change and adaptation science; transformational adaptations as driven by changes in climate, policy, values and attitudes influencing the design of farming systems; Development and application of farming systems design tools and methods for impact, scenario and case study analysis; managing the complexities of dynamic agricultural systems; innovation systems and multi stakeholder arrangements that support or promote change and (or) inform policy decisions.
