摘要

本研究旨在分析骆驼养殖对牧民家庭生计的贡献。我们对 200 户家庭进行了调查,其中 108 户位于恩贾梅纳近郊,102 户位于乍得中部的菲特里牧区。数据分析采用了两种家庭生计策略(每个地区一种)。骆驼牧民家庭基本上都是专业户,骆驼至少占畜群的 80%(以热带牲畜单位 TLU 计)。这些家庭是畜牧业专业户,其中 60% 的家庭不从事任何种植业。恩贾梅纳城郊的骆驼养殖与菲特里牧区不同,因为牛奶销售对家庭的货币收入非常重要。在菲特里牧区和恩贾梅纳近郊区,牛奶自给率分别占骆驼养殖总产值的 45%和 21%。在菲特里,家庭还利用活畜生产肉类,主要用于销售,少量用于自食。在菲特里牧区,活畜的附加值占骆驼总产值的 55%(3.6 头/年),因为牛奶自给自足,而在恩贾梅纳近郊,活畜的附加值仅占 10%(1.6 头/年),因为牛奶销售。与恩贾梅纳近郊区的家庭相比,菲特里家庭平均每个成人当量(AE)的牲畜数量增加了一倍(14 TLU/AE 与 7 TLU/AE)。菲特里的牲畜构成更加多样化,有骆驼(占牲畜总头数的 80%)、小反刍动物和牛,而恩贾梅纳近郊区的家庭除了饲养小反刍动物外,还更多地饲养骆驼(占牲畜总头数的 90%)。在菲特里,40% 的家庭种植农作物,而在恩贾梅纳周边地区只有 24%。在恩贾梅纳近郊,小规模家庭(4.8 AE)的牲畜饲养量为 7.8 TLU/AE,超大规模家庭(9.3 AE)的牲畜饲养量为 8.2 TLU/AE,而在菲特里,小规模家庭的资本禀赋非常高(24.4 TLU/AE),中等规模家庭的资本禀赋中等,为 13.9 TLU/AE,而大规模家庭的资本禀赋较低,为 10.8 TLU/AE。在这两个地区,骆驼养殖为四分之三的家庭提供了每头 AE 每天超过 663 非洲法郎的毛利,相当于国家贫困线。然而,只有 16% 的家庭的毛利高于行业间最低保障工资,估计为 2000 非洲法郎/天。这种专业化的骆驼放牧方式使牧民能够很好地适应干旱环境。还需要开展更多的研究工作,为骆驼作为生计战略基础的潜力提供全球视野。

The importance of camel (Camelus dromedaries) in the livelihoods of herders: the case of camel herders’ households in peri-urban N’Djamena and pastoral Fitri, Chad

The objective of this study was to analyse the contribution of camel farming to pastoral household livelihood. A survey was conducted among 200 households, 108 in peri-urban N’Djamena and 102 in pastoral Fitri in central Chad. Two types (one per zone) of household livelihood strategies were used to analyse the data. Camel herders’ households are largely specialised, with camels comprising at least 80% of herds (in terms of tropical livestock units, TLU). Such households are livestock farming specialists, with 60% of households not undertaking any cultivation. Camel farming in peri-urban N’Djamena differed from that in pastoral Fitri because of the importance of milk sales that contribute to the monetary income of families. Milk self-consumption as part of the gross product of camel farming represented 45% for pastoral Fitri and 21% for peri-urban N’Djamena. Households also exploited live animals for meat, mainly for sale, and a little for self-consumption in Fitri. The added value of live animals represented 55% (3.6 animals/year) of camel gross product in pastoral Fitri, because of the volume of milk self-consumption, and only 10% (1.6 animals/year) in peri-urban N’Djamena, because of milk sales. The livestock per adult equivalent (AE) was, on average, double for households in Fitri compared to those in peri-urban N’Djamena (14 vs 7 TLU/AE). Livestock composition was more diversified in Fitri, with camels (80% of TLUs), small ruminants and cattle, whereas households in peri-urban N’Djamena were even more specialised towards camels (90% of TLUs), besides keeping small ruminants. At Fitri, 40% of households grew crops, compared with only 24% around N’Djamena. The size of livestock holdings ranged from 7.8 TLU/AE for small-size households (4.8 AE) to 8.2 TLU/AE for very large-sized households (9.3 AE) in peri-urban N’Djamena, whereas at Fitri small households had a very high capital endowment (24.4 TLU/AE), medium-sized households were moderately endowed, with 13.9 TLU/AE, and large households were poorly endowed, with 10.8 TLU/AE. In both areas, camel farming provided a daily gross margin per AE over 663 CFA francs/day for three quarters of households, which corresponds to the national poverty threshold. However, only 16% of households generated a gross margin higher than the guaranteed interprofessional minimum wage, estimated at 2000 CFA francs/day. This specialisation of moving to camel herding allowed herders to get well adapted to arid environments. Additional research work is needed to provide a global vision of the potential of camels as a basis for livelihood strategies.

期刊介绍: The Rangeland Journal publishes original work that makes a significant contribution to understanding the biophysical, social, cultural, economic, and policy influences affecting rangeland use and management throughout the world. Rangelands are defined broadly and include all those environments where natural ecological processes predominate, and where values and benefits are based primarily on natural resources. Articles may present the results of original research, contributions to theory or new conclusions reached from the review of a topic. Their structure need not conform to that of standard scientific articles but writing style must be clear and concise. All material presented must be well documented, critically analysed and objectively presented. All papers are peer-reviewed. The Rangeland Journal is published on behalf of the Australian Rangeland Society.
