Changing land use patterns in southern Africa have potential to dramatically alter the prospects for carnivore conservation. Understanding these influences is essential for conservation planning. We interviewed 250 ranchers in Namibia to assess human tolerance towards and the distribution of large carnivores. Cheetahs (Acinonyx jubatus), leopards (Panthera pardus) and brown hyaenas (Hyaena brunnea) were widely distributed on Namibian farmlands, spotted hyaenas (Crocuta crocuta) had a narrower distribution, and wild dogs (Lycaon pictus) and lions (Panthera leo) are largely limited to areas near source populations. Farmers were most tolerant of leopards and least tolerant of lions, wild dogs and spotted hyaenas. Several factors relating to land use correlated consistently with carnivore-presence and landowner tolerance. Carnivores were more commonly present and/or tolerated where; wildlife diversity and biomass were higher; income from wildlife was higher; income from livestock was lower; livestock biomass was lower; in conservancies; game fencing was absent; and financial losses from livestock depredation were lower. Efforts to create conditions whereby the costs associated with carnivores are lowest, and which confer financial value to them are likely to be the most effective means of promoting carnivore conservation. Such conditions are achieved where land owners pool land to create conservancies where livestock are replaced with wildlife (or where livestock husbandry is improved) and where wildlife generates a significant proportion of ranch income. Additional measures, such as promoting improved livestock husbandry and educational outreach efforts may also help achieve coexistence with carnivores. Our findings provide insights into conditions more conducive to the persistence of and tolerance towards large carnivores might be increased on private (and even communal) lands in Namibia, elsewhere in southern and East Africa and other parts of the world where carnivore conservation is being attempted on private lands.
在南非,土地利用方式的变化有可能极大地改变食肉动物保护的前景。了解这些影响对于保护规划至关重要。我们采访了纳米比亚的 250 名牧场主,以评估人类对大型食肉动物的容忍度和它们的分布情况。在纳米比亚的农田上,广泛分布着猎豹(Acinonyx jubatus)、豹(Panthera pardus)和棕鬣狗(Hyaena brunnea),斑鬣狗(Crocuta crocuta)的分布范围较窄,而野狗(Lycaon pictus)和狮子(Panthera leo)则主要局限于接近其种群源的地区。农民对豹的容忍度最高,对狮子、野狗和斑鬣狗的容忍度最低。与土地利用相关的几个因素与食肉动物的存在和土地所有者的容忍度密切相关。在以下情况下,食肉动物更常见,或更容易被容忍:野生动物多样性和生物量更高;野生动物收入更高;家畜收入更低;家畜生物量更低;在保护区内;没有设置猎场围栏;家畜遭受掠夺的经济损失更低。创造条件,使与食肉动物相关的成本最低,并为它们赋予经济价值,这可能是促进食肉动物保护的最有效手段。在这些条件下,土地所有者可以将土地集中起来,创建保护区,在保护区内用野生动物(或改善家畜管理)取代家畜,同时野生动物可以为牧场主带来很大一部分收入。此外,还可以采取一些措施,如促进改进家畜管理和开展教育推广工作,这也有助于实现与食肉动物共存。我们的研究结果为纳米比亚乃至南部非洲和东非其他地区以及世界其他地区的私有(甚至公有)土地上,如何增加大型食肉动物的生存机会和容忍度提供了深入的了解。
