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.

Abstract Human and animal mobility lies at the core of any nomadic pastoralist system. Anthropological studies of migratory patterns of mobile pastoralists’ movements have revealed two universal sets of factors—ecological and non-ecological—that influence such movements differently. Our study focuses on the nomadic movement of the Yamal Nenets reindeer herders in the Russian Arctic using a microregional approach to study the indigenous communities on a large scale. The Nenets households of the Mordyyakha microregion in the northwest of the Yamal Peninsula have changed winter pasture sites several times over the past 15–20 years, while maintaining a stable summer route. Based on fieldwork among these people, we analyse how environmental and non-environmental factors influence the dynamics of their summer and winter meridional nomadic routes. We argue that long-term changes in their winter mobility are mainly related to the quality of pastures. Changing winter sites is a strategy that relates to ecological factors and still remains relevant for the households migrating via the meridional pastoral corridors of Yamal. In contrast, changing summer areas, as a rule, occurs in response to developing industry and, thus, relates to non-ecological factors.

Abstract Pastoralist adaptation strategies have to address multiple, overlapping, and often inter-related processes of socio-ecological change. The present study addresses the need for inter-regional comparative studies that account for different geographic, climate, and socio-economic contexts in order to understand how pastoralists adapt to changes in livelihood conditions. The paper uses data from a unique survey study of pastoralist households in four neighbouring counties in dryland Kenya. Taking our point of departure from an empirically based classification of the livelihood strategies available to pastoralists in the Horn of Africa, the survey offers novel insights into adaptation and fodder management strategies of pastoralist individuals and households. The results show that the use of migration as a strategy is more dependent on the ability to migrate than climate conditions. This is the case in localities where a substantial part of the land is subdivided, the population density is high, and where opportunities for migration are subsequently restricted. Diversification of livelihoods as a strategy is largely defined by opportunity. Intensification through active fodder management is mainly common in areas where there has been a proliferation of managed enclosures. Climate change will test the adaptive capacity of pastoralists in the studied region, and diversification and intensification strategies of both herd composition and livelihoods can be seen as strategies for increased climate resilience.

Abstract Extensive sheep pasturing in alpine regions has a long tradition and fulfils numerous sociological, economic and ecological functions. The effects of sheep grazing on the floristic composition and vice versa depend on various factors. Knowledge of potential interrelations is crucial to developing adequate management systems to maintain pasture productivity and its unique biodiversity. The aim of the present study was to discuss the potential interrelations between movement and selective grazing behaviour of free-ranging unherded sheep and the botanical composition of high-altitude mountain pastures in northern Italy. General movement patterns were determined by using GPS tracking. The floristic composition of areas roamed by the sheep was analysed by collecting physical data during the summer of 2022. The energy content of ingested herbage biomass was determined based on faecal samples. Ranging between 2296 and 3015 m above sea level (a.s.l.), the average altitude used by the sheep was 2654 m a.s.l. Correlation analyses showed that the sheep used significantly higher altitudes with increasing temperature and sunshine duration and with decreasing air humidity and rainfall. A clear selective grazing behaviour was revealed, namely a preference for species with better nutritional attributes. Poa alpina was the most preferred species, while areas dominated by Nardus stricta were avoided. Furthermore, the sheep showed an uphill migration over the season, possibly caused by the delayed start of grassland growth at higher altitudes. Analyses of faecal samples revealed sufficient energy contents, presumably as a result of the targeted selection of nutritious plant species. Future studies should evaluate the feeding value of herbage on offer in order to validate the current results. The study highlights the opportunity of animal tracking in remote areas and provides indications for selective grazing of sheep under conditions of free choice.
高寒地区放羊有着悠久的传统,并具有多种社会、经济和生态功能。放牧对植物区系组成的影响取决于多种因素。了解潜在的相互关系对于建立适当的管理系统以保持牧场生产力及其独特的生物多样性至关重要。本研究的目的是讨论自由放养的非放牧羊的运动和选择性放牧行为与意大利北部高海拔山地牧场的植物组成之间的潜在相互关系。使用GPS跟踪确定一般运动模式。通过在2022年夏季收集物理数据,分析了羊漫游地区的植物区系组成。根据粪便样品测定摄入的牧草生物量的能量含量。在海拔2296 ~ 3015 m (a.s.l)范围内,绵羊的平均海拔高度为2654 m (a.s.l)。相关分析表明,绵羊利用的海拔高度显著升高,气温和日照时数增加,空气湿度和降雨量减少。揭示了明显的选择性放牧行为,即对营养属性较好的物种的偏好。高山Poa是最受欢迎的物种,而Nardus的优势区则被避开。此外,绵羊在季节中表现出上坡迁移,这可能是由于高海拔草原生长延迟的原因。对粪便样本的分析显示了足够的能量含量,这可能是有针对性地选择有营养的植物物种的结果。未来的研究应评估所提供的牧草的饲养价值,以验证目前的结果。该研究强调了在偏远地区进行动物跟踪的机会,并为在自由选择的条件下选择性放牧羊提供了指示。

Abstract Pastoralist tenure systems are highly complex. Where customary institutions are functioning well, pastoralist women access and use resources as a member of a pastoralist group. Although policy and legislation call for more equity across societies, providing individual titles to women is not necessarily the answer. Strengthening women’s rights within the collective society while also supporting women’s capacities and abilities to participate meaningfully in decision-making processes and hold leadership positions will support more sustainable gender equality outcomes. Participatory rangeland management (PRM) is an approach developed in Ethiopia in 2010 that was then piloted by non-governmental organisations in several parts of the country in a bid to improve the security of tenure and good governance of rangelands, more inclusive participation of pastoralists in decisions pertaining to their lands and improve rangeland productivity. While not an explicit aim, it also sought women’s empowerment as part of the participatory process. A review of PRM implementation in Oromia and Afar regions, Ethiopia, showed that in the majority of cases, women participated equally with men in the PRM process. Women’s and men’s opinions on the involvement and satisfaction of PRM implementation activities were compared favourably. Overall, community members believed that PRM has improved women’s roles in rangeland management leadership and decision-making processes and their access to rangeland resources, thereby encouraging a transformative process of improving gender equality and women’s empowerment in pastoralist societies. This article considers the implications of these results for pastoral women and to what degree they have contributed to their empowerment. A conceptualised women’s empowerment framework is used for the analysis.
