Across the developing world, humans and free-ranging domestic dogs share common spaces. The relationship between these dogs and humans can range from one of dependence, to apathy, to conflict. Given the high number of humans attacked by dogs every year in India, and the lack of an effective population control strategy, we seek to provide insights into the conflict and propose alternative population management options based on reducing the carrying capacity of the environment. We used a mixed methods approach to understand both ecological and sociological underpinnings of free-ranging dog-human relationships in Bangalore, India. We conducted a photographic capture-recapture survey of free-ranging dogs to estimate population size and linked it to the availability of potential food sources. We also conducted a qualitative survey to assess attitudes of residents towards the dog population. We found that dog population varied from 192 to 1888 per square kilometre across a gradient of housing densities. The density of houses, bakeries and garbage piles were significant predictors of dog population size. Crucially, as low as 10 to 18% of houses supported the large population of dogs, highlighting the need for residents to act responsibly towards the dogs. Further, we found that garbage, although significant, is a secondary food source to household-maintained dogs. Since on the whole, respondents expressed the desire for a reduction in dog population, we suggest decreasing the carrying capacity of the environment by targeting these three food sources.

“流浪的胃口”:对印度班加罗尔与人类社区一起生活的自由放养狗的社会生态分析

在整个发展中世界,人类和自由放养的家犬共享公共空间。这些狗和人类之间的关系可以从依赖、冷漠到冲突。鉴于印度每年有大量人类被狗袭击,并且缺乏有效的人口控制策略,我们寻求提供对冲突的见解,并提出基于降低环境承载能力的替代人口管理方案。我们使用混合方法来了解印度班加罗尔自由放养的狗与人关系的生态和社会学基础。我们对自由放养的狗进行了摄影捕捉-重新捕捉调查,以估计种群规模并将其与潜在食物来源的可用性联系起来。我们还进行了一项定性调查,以评估居民对狗群的态度。我们发现,在不同的住房密度梯度下,狗的数量从每平方公里 192 只到 1888 只不等。房屋、面包店和垃圾堆的密度是狗群规模的重要预测指标。至关重要的是,只有 10% 到 18% 的房屋供养了大量的狗,这凸显了居民对狗采取负责任的行动的必要性。此外,我们发现垃圾虽然很重要,但却是家庭饲养的狗的次要食物来源。由于总体而言,受访者表示希望减少狗的数量,我们建议通过针对这三种食物来源来降低环境的承载能力。我们发现,在不同的住房密度梯度下,狗的数量从每平方公里 192 只到 1888 只不等。房屋、面包店和垃圾堆的密度是狗群规模的重要预测指标。至关重要的是,只有 10% 到 18% 的房屋供养了大量的狗,这凸显了居民对狗采取负责任的行动的必要性。此外,我们发现垃圾虽然很重要,但却是家庭饲养的狗的次要食物来源。由于总体而言,受访者表示希望减少狗的数量,我们建议通过针对这三种食物来源来降低环境的承载能力。我们发现,在不同的住房密度梯度下,狗的数量从每平方公里 192 只到 1888 只不等。房屋、面包店和垃圾堆的密度是狗群规模的重要预测指标。至关重要的是,只有 10% 到 18% 的房屋供养了大量的狗,这凸显了居民对狗采取负责任的行动的必要性。此外,我们发现垃圾虽然很重要,但却是家庭饲养的狗的次要食物来源。由于总体而言,受访者表示希望减少狗的数量,我们建议通过针对这三种食物来源来降低环境的承载能力。低至 10% 至 18% 的房屋供养了大量的狗,这凸显了居民对狗采取负责任的行动的必要性。此外,我们发现垃圾虽然很重要,但却是家庭饲养的狗的次要食物来源。由于总体而言,受访者表示希望减少狗的数量,我们建议通过针对这三种食物来源来降低环境的承载能力。低至 10% 至 18% 的房屋供养了大量的狗,这凸显了居民对狗采取负责任的行动的必要性。此外,我们发现垃圾虽然很重要,但却是家庭饲养的狗的次要食物来源。由于总体而言,受访者表示希望减少狗的数量,我们建议通过针对这三种食物来源来降低环境的承载能力。
