Abstract

Abstract Livestock production has undergone an industrial revolution over the past few decades. This has resulted in the enormous generation of livestock manure, particularly in agro-pastoral systems. Agricultural productivity in these systems largely depends on livestock manure. However, some of these communities are struggling with goat manure disposal. In addition, livestock manure requires proper treatment before application to agricultural land, because it contains toxic heavy metals and pathogenic microorganisms. The review aimed to demonstrate that poor manure management has environmental consequences; thus, interventions that will promote local community livelihood benefits from animal wastes are germane. In many other communities in sub-Saharan Africa (SSA), horticulture or crop production is minimal, due to erratic rainfall hence, most of the manure lies idle in abandoned kraal pens or is heaped outside the pens with no designed plan. Manure should be viewed as a resource, rather than a waste product. The environmental consequences associated with such manure management are not known and should be probed further. Deliberate efforts to explore the land and environmental risks associated with the non-use of livestock manure are germane to promoting environmental stewardship. The use of manure as feedstock for anaerobic digesters offers the greatest potential for sustainable management in SSA.
在撒哈拉以南非洲使用羊粪的好处、问题和前景
在过去的几十年里,畜牧业经历了一场工业革命。这导致了大量牲畜粪便的产生,特别是在农牧系统中。这些系统的农业生产力在很大程度上取决于牲畜粪便。然而,其中一些社区正在努力处理山羊粪便。此外,牲畜粪便在用于农田之前需要进行适当的处理,因为它含有有毒的重金属和致病微生物。这篇综述的目的是证明粪便管理不善会造成环境后果;因此,促进当地社区从动物粪便中获得生计效益的干预措施是密切相关的。在撒哈拉以南非洲(SSA)的许多其他社区,由于降雨不稳定,园艺或作物生产很少,因此,大部分粪便被闲置在废弃的kraal围栏中,或者在没有设计计划的情况下堆在围栏外。粪肥应该被视为一种资源,而不是一种废物。与这种粪便管理有关的环境后果尚不清楚,应进一步探讨。刻意探索与不使用禽畜粪便有关的土地和环境风险,与促进环境管理密切相关。使用粪便作为厌氧消化器的原料为SSA的可持续管理提供了最大的潜力。

期刊介绍: Pastoralism: Research, Policy and Practice is an interdisciplinary and peer-reviewed journal on extensive livestock production systems throughout the world. Pastoralists rely on rangelands and livestock for their livelihoods, but exhibit different levels of mobility and market involvement, and operate under a variety of different land tenure regimes. Pastoralism publishes research that influences public policy, to improve the welfare of these people and better conserve the environments in which they live. The journal investigates pastoralism from a variety of disciplinary perspectives across the biophysical, social and economic sciences. This is not applied research in the traditional sense, but relevant research, sometimes even basic research, with the capacity ultimately to change the way practical people do business. Predicting what kind of research will fulfil this role is virtually impossible. What we can do is keep policy makers, practitioners and pastoralists talking to scientists and researchers and aware of each others'' concerns.
