The population of Timor deer (Rusa timorensis), an Indonesian endemic, continues to decline in its natural habitat, so captive breeding could become a source of individuals to bolster wild population. Support for captive breeding programs may be stronger if captive breeding also provided meat for human consumption. Thus, sustainable captive yields could be expected to support both conservation interests and food needs. The aim of this research is to evaluate the environmental impact, based on global warming potential (GWP), of two Timor deer breeding systems, that is, a farming system and a ranching system, in West Java, Indonesia. Life cycle assessment methodology was used for the evaluation to gain a cradle-to-gate perspective. The functional unit used was 1 kg of Timor deer live weight in captivity. The main result of the study indicated that the GWP per kg of Timor deer was estimated at 17.30 kgCO2eq (farming system) and 17.60 kgCO2eq (ranching system). The largest GWP in both systems was derived from cultivation activities and infrastructure development. In general, there is no significant difference in the GWP of the two breeding systems studied. This was due to the similar overall management adopted by the two breeding systems, especially the use of food types and infrastructure materials. Currently, the environmental dimension, especially the emissions from Timor deer breeding activities, is not a major concern, but in the future, breeding management should pay attention to the efficient use of the food and infrastructure to make it more environmentally friendly.

圈养帝汶鹿的可持续性:印度尼西亚西爪哇的圈养繁殖系统

印度尼西亚特有的帝汶鹿 (Rusa timorensis) 的数量在其自然栖息地中继续下降,因此圈养繁殖可能成为增加野生种群数量的个体来源。如果圈养繁殖也提供供人类食用的肉类,那么对圈养繁殖计划的支持可能会更强。因此,可持续的圈养产量有望支持保护利益和粮食需求。本研究的目的是根据全球变暖潜能值 (GWP) 评估印度尼西亚西爪哇的两种帝汶鹿养殖系统(即养殖系统和牧场系统)对环境的影响。生命周期评估方法用于评估以获得从摇篮到大门的视角。使用的功能单位是 1 公斤圈养帝汶鹿的活重。研究的主要结果表明,每公斤帝汶鹿的 GWP 估计为 17.30 kgCO2eq(养殖系统)和 17.60 kgCO2eq(牧场系统)。两个系统中最大的 GWP 来自种植活动和基础设施开发。一般而言,所研究的两种育种系统的 GWP 没有显着差异。这是由于两个育种系统采用了相似的整体管理,特别是食物类型和基础设施材料的使用。目前,环境维度,特别是帝汶鹿养殖活动的排放,不是主要问题,但未来养殖管理应注意食物和基础设施的有效利用,使其更加环保。30 kgCO2eq(农业系统)和 17.60 kgCO2eq(牧场系统)。两个系统中最大的 GWP 来自种植活动和基础设施开发。一般而言,所研究的两种育种系统的 GWP 没有显着差异。这是由于两个育种系统采用了相似的整体管理,特别是食物类型和基础设施材料的使用。目前,环境维度,特别是帝汶鹿养殖活动的排放,不是主要问题,但未来养殖管理应注意食物和基础设施的有效利用,使其更加环保。30 kgCO2eq(农业系统)和 17.60 kgCO2eq(牧场系统)。两个系统中最大的 GWP 来自种植活动和基础设施开发。一般而言,所研究的两种育种系统的 GWP 没有显着差异。这是由于两个育种系统采用了相似的整体管理,特别是食物类型和基础设施材料的使用。目前,环境维度,特别是帝汶鹿养殖活动的排放,不是主要问题,但未来养殖管理应注意食物和基础设施的有效利用,使其更加环保。所研究的两个育种系统的 GWP 没有显着差异。这是由于两个育种系统采用了相似的整体管理,特别是食物类型和基础设施材料的使用。目前,环境维度,特别是帝汶鹿养殖活动的排放,不是主要问题,但未来养殖管理应注意食物和基础设施的有效利用,使其更加环保。所研究的两个育种系统的 GWP 没有显着差异。这是由于两个育种系统采用了相似的整体管理,特别是食物类型和基础设施材料的使用。目前,环境维度,特别是帝汶鹿养殖活动的排放,不是主要问题,但未来养殖管理应注意食物和基础设施的有效利用,使其更加环保。
