The results showed that the heights of Stipa klemenzis and Cleistogenes songorica were similar among economic treatments. And the height of Allium polyrhizm had no signiifcant differences between high-economic-level （HEL） and low-economic-level （LEL） treatments. There were no signiifcant difference among treatments in the canopy cover of C. songorica. The densities of dominant species （S. klemenzis, C. songorica and A. polyrhizm） were signiifcantly similar among treatments. Aboveground community biomass in reference area （CK） was higher than that in other three treatments in 2011, but their biomass showed no signiifcant difference among three economic treatments;for 2012, biomass in HEL was higher than low-economic-level treatment （LEL）, while the biomass in middle-economic-level treatment （MEL） and CK was similar to that in HEL and LEL, respectively. Aboveground biomass of S. klemenzis and C. songorica was similar among treatments in both 2011 and 2012. Biomass of A. polyrhizum had no signiifcant difference between HEL and MEL. Households of LEL had rented out excess lands and those of HEL had leased their available lands thus resulting uniform utilization and convergence of pastoralist households’ pastures across all economic levels.展开更多

Specifically, climate change is acknowledged as a vital challenge to pastoralist production systems. However, limited research attention was given to exploring the determinants of climate change adaptation strategies in the southeastern part of Ethiopia. Thus, the study tried to assess the predictors of pastoralists’ climate change adaptation strategies in the Korahey zone of Ethiopia. The study was based on a survey of 215 representative pastoralist households were randomly selected from the three districts of the Korahey zone. To achieve the objective, household questionnaire surveys, key informant interviews, and focus group discussions were conducted to collect data at the household as well as the district level. Data were analyzed using descriptive statistics like percentage, frequency, mean, and inferential statistics (multinomial logit model). Multinomial logit was employed to analyze the determinant factors of pastoralists’ adaptation strategies to climate change. The finding shows that household pastoralists adopt different climate change adaptation strategies in their locality;from this herd diversification (10.7%), storage of fodder (14.4%), mobility (23.7%), Livestock off-take (12%), saving scheme (8.8%) and household and herd splitting (15.3%) are the major pastoralists’ adaptation strategies to climate change in the study area. The results of the multinomial logit model show that sex, age, family size, access to climate information, access to credit services, access to extension services and livestock ownership were identified as the major determinants factors of climate change adaptation strategies in Korahey zone. The study recommended that the local government, planners and decision-makers should give awareness regarding the role of information in the pastoralists’ adoption of climate change adaptation strategies and enhance extension services to support pastoralists in their ada展开更多

This system is mainly based on seasonal migration of pastoralists and their livestock herds between upland and lowland pastures. Traditionally pastoral activities make significant contributions to mountain livelihood subsistence, regional economies and environmental sustainability. However, the pastoralist’s lifestyle and their economies are increasingly confronted to various socio-political, economic and ecological stresses from the last few decades. Extensive literature reviewed on this subject with the aim to explore the current emerging challenges faced by pastoral communities in different pastoral regions. It has been revealed from literature that the prevalent socio-political and economic stress on pastoralism caused by modernization, insecure land tenure, integration of market economy, civil insecurities and pastoralist’s exclusion in states policies while ecological stress on pastoral activities emerged with increasing focus on nature conservation in pastoral regions and climate change induced hazards and disasters. As a consequence of these challenges, pastoral households are abandoning livestock herding–as a traditional way of life and are in continuous transition to transform their pastoral practices and institutions. Thus, the attention and consultation of key stakeholders are needed toward pastoral resource development that improve and sustain traditional pastoral practices in a socio-politically and ecologically stressed environment of the world.展开更多

In a second step, field testing of an intervention on milk and meat hygiene was carried out at household level. Survey results indicated that about 50% of marketable camel milk was not sold, 30% of marketed camel milk per annum was sold in sour state at US$ 0.13 lower that the price of a litre of fresh milk while processed meat got spoiled along the chain. Annual economic losses associated with milk spoilage were estimated at US$ 961,538.5. Preliminary findings of the field testing indicated that an additional 3 million litres of camel milk was sold in fresh state, giving an annual saving of US$ 384,615.4. Increased profitability of up to 60% compared to 30% before the intervention was reported among nyirinyiri processors. In conclusion, economic potential of the camel could be fully exploited by facilitating adoption of interventions such as hygiene, among others at all levels of the camel milk and meat value chains.展开更多

However, the livestock keepers in the ASALs view the CQL as an impediment to their main source of livelihoods because it entails livestock movement restrictions, thus constraining unfettered livestock marketing. Available literature shows that there is a dearth of information on the economics of livestock diseases control in Kenya in terms of its impacts on social welfare. Employing the CQL as a case study, this study shows that an application of analytic techniques that combine disease risk analysis and conventional cost-benefit modelling that incorporates some aspects that are specific to livestock diseases and their control strategies can generate indices of economic impacts of livestock diseases control on social welfare. The study finds that the livestock keepers and traders in Kenya do not consider CBPP a major problem to warrant livestock movement restrictions, yet the official records of the veterinary authorities indicate that CBPP is a major threat to the cattle industry in Kenya. Annually, the government spends substantial resources on the CQL operation and maintenance and also on CBPP surveillance and monitoring to contain the CBPP menace in Kenya. This study shows that such expenditures are economically and socially justifiable. Nevertheless, the study finds some operational inefficiencies in the enforcement of the CQL requirements. The authors, therefore, undertake an evaluation of alternative CBPP control strategies and conclude that it would be more cost effective to shift the 展开更多

Classic strategies for social services were always based on a single sector, focused on settled populations, and hardly reached mobile communities. This paper aims to show a cross-sector approach as a part of solutions to provide social services for mobile pastoralist communities and describes the ongoing scaling-up process. The method used is based on a transdisciplinary approach which involves target communities and authorities in all processes through workshops and site visits. Interventions adopted the concept of ＂one health＂ benefiting of an added value of closer cooperation between human and animal health. This approach was tested with joint interventions between human and animal health, which provided access to health services for unreached communities and saved resource when compared with single sector intervention. Such approaches could be extended to other social services within cross-sector interventions such as the delivery of basic education in nomadic areas. Such a strategy was validated by the communities and authorities and was further transformed into a national programme after a series of six national stakeholders＇ seminars. The cross-sector intervention will provide a minimum package of services （MPS） without compromising the structural services.展开更多

文摘Pastoralism is a viable socio-economic system-shaped by landless and agro-pastoral communities in many pastoral regions of the world. This system is mainly based on seasonal migration of pastoralists and their livestock herds between upland and lowland pastures. Traditionally pastoral activities make significant contributions to mountain livelihood subsistence, regional economies and environmental sustainability. However, the pastoralist’s lifestyle and their economies are increasingly confronted to various socio-political, economic and ecological stresses from the last few decades. Extensive literature reviewed on this subject with the aim to explore the current emerging challenges faced by pastoral communities in different pastoral regions. It has been revealed from literature that the prevalent socio-political and economic stress on pastoralism caused by modernization, insecure land tenure, integration of market economy, civil insecurities and pastoralist’s exclusion in states policies while ecological stress on pastoral activities emerged with increasing focus on nature conservation in pastoral regions and climate change induced hazards and disasters. As a consequence of these challenges, pastoral households are abandoning livestock herding–as a traditional way of life and are in continuous transition to transform their pastoral practices and institutions. Thus, the attention and consultation of key stakeholders are needed toward pastoral resource development that improve and sustain traditional pastoral practices in a socio-politically and ecologically stressed environment of the world.

文摘Introduction:Community perception plays a significant role in rangeland resource management.Traditional rangeland management practices by the pastoral communities are based on accumulated knowledge in connection to their local environment.Pastoralism played a vital role in food production and sustaining its inhabitants in arid environment for millennia.However,national policies and development interventions in East African pastoral systems have often overlooked pastoralism while centered on the modernization of agricultural sector for economic development and poverty reduction.Methods:We used household survey,focus group discussion,key informant interview,and individual questionnaire to understand the perceptions and attitude of Afar pastoralists towards rangeland resource use and conservation practices,as well as impacts of development intervention on traditional rangeland resource use and conservation practices.The data were analyzed using index ranking and descriptive statistics.Results:The results showed that livestock holding per household was higher on average(22.90±2.27 Tropical Livestock Unit(TLU))in the non-intervened woreda than in the intervened woreda(8.30±3.85 TLU).Respondents mentioned that livestock productivity was adversely affected by a number of factors such as invasion of Prosopis juliflora(Dergi Hara),shrinkage in the capacity of rangelands(Beadu and Bebea’),and recurrent droughts.Scarcity of grazing resources attributed to the invasion of Dergi Hara and drought created livestock feed crisis with strong implication on the livelihood of pastoralists.Our results showed that the traditional resource management practices such as mobility,herd splitting,and diversification had a role to contribute to the improvement of rangeland management and conservation of biodiversity.Traditional rules and seasonal-based grazing patterns of riversides during drought were perceived as key elements for rangeland resource management and conservation of rangeland resources in the study area.Conclusions:Communi
文摘The main grassland plain of Nech Sar National Park(NSNP)is a federally managed protected area in Ethiopia designated to protect endemic and endangered species.However,like other national parks in Ethiopia,the park has experienced significant land cover change over the past few decades.Indeed,the livelihoods of local populations in such developing countries are entirely dependent upon natural resources and,as a result,both direct and indirect anthropogenic pressures have been placed on natural parks.While previous research has looked at land cover change in the region,these studies have not been spatially explicit and,as a result,knowledge gaps in identifying systematic transitions continue to exist.This study seeks to quantify the spatial extent and land cover change trends in NSNP,identify the strong signal transitions,and identify and quantify the location of determinants of change.To this end,the author classifies panchromatic aerial photographs in 1986,multispectral SPOT imagery in 2005,and Sentinel imagery in 2019.The spatial extent and trends of land cover change analysis between these time periods were conducted.The strong signal transitions were systematically identified and quantified.Then,the basic driving forces of the change were identified.The locations of these transitions were also identified and quantified using the spatially explicit statistical model.The analysis revealed that over the past three decades(1986–2019),nearly 52%of the study area experienced clear landscape change,out of which the net change and swap change attributed to 39%and 13%,respectively.The conversion of woody vegetation to grassland(~5%),subsequently grassland-to-open-overgrazed land(28.26%),and restoration of woody vegetation(0.76%)and grassland(0.72%)from riverine forest and open-overgrazed land,respectively,were found to be the fully systematic transitions whereas the rest transitions were recorded either partly systematic or random transitions.The location of these most systematic land cover transitions identified thr
文摘A survey to identify constraints and design strategies to improve the camel milk and meat value chains was conducted in northern Kenya using Participatory Integrated Community Development （PICD）, Focus Group Discussions （FGD）, among other methods. In a second step, field testing of an intervention on milk and meat hygiene was carried out at household level. Survey results indicated that about 50% of marketable camel milk was not sold, 30% of marketed camel milk per annum was sold in sour state at US$ 0.13 lower that the price of a litre of fresh milk while processed meat got spoiled along the chain. Annual economic losses associated with milk spoilage were estimated at US$ 961,538.5. Preliminary findings of the field testing indicated that an additional 3 million litres of camel milk was sold in fresh state, giving an annual saving of US$ 384,615.4. Increased profitability of up to 60% compared to 30% before the intervention was reported among nyirinyiri processors. In conclusion, economic potential of the camel could be fully exploited by facilitating adoption of interventions such as hygiene, among others at all levels of the camel milk and meat value chains.
文摘Contagious bovine pleuro-pneumonia （CBPP） is one of the endemic and life-threatening livestock diseases in the arid and semi-arid land areas （ASALs） of Kenya, which justify the case for the control of livestock diseases to avoid the spread of such diseases from the ASALs to the rest of the country, and a CBPP control quarantine line （CQL） that to help prevent the spread of CBPP from the ASALs of North-eastern Kenya to the rest of the country has been in existence since the colonial （pre-1963） times in Kenya. However, the livestock keepers in the ASALs view the CQL as an impediment to their main source of livelihoods because it entails livestock movement restrictions, thus constraining unfettered livestock marketing. Available literature shows that there is a dearth of information on the economics of livestock diseases control in Kenya in terms of its impacts on social welfare. Employing the CQL as a case study, this study shows that an application of analytic techniques that combine disease risk analysis and conventional cost-benefit modelling that incorporates some aspects that are specific to livestock diseases and their control strategies can generate indices of economic impacts of livestock diseases control on social welfare. The study finds that the livestock keepers and traders in Kenya do not consider CBPP a major problem to warrant livestock movement restrictions, yet the official records of the veterinary authorities indicate that CBPP is a major threat to the cattle industry in Kenya. Annually, the government spends substantial resources on the CQL operation and maintenance and also on CBPP surveillance and monitoring to contain the CBPP menace in Kenya. This study shows that such expenditures are economically and socially justifiable. Nevertheless, the study finds some operational inefficiencies in the enforcement of the CQL requirements. The authors, therefore, undertake an evaluation of alternative CBPP control strategies and conclude that it would be more cost effective to shift the
文摘Land use conflicts are complex disputes that contribute at large in terms of negative social and economic impacts within the heterogeneous societies.The mechanisms of success for land use conflict resolution still need further research because of various mindsets of the people.In this paper,the issues of land conflicts between farmers and pastoralists in Tanzania mainland which could lead to low economic development are reviewed and the general causes and effects of land use conflicts are outlined.Poor land governance,inappropriate of land use plans,inadequate land policies,land tenure insecurity,corruption and population increases are cited as being among of the main offenders fuelling land use conflicts in Tanzania.
文摘Mobile pastoralist communities in Sahel countries have serious problems of access to social services. Classic strategies for social services were always based on a single sector, focused on settled populations, and hardly reached mobile communities. This paper aims to show a cross-sector approach as a part of solutions to provide social services for mobile pastoralist communities and describes the ongoing scaling-up process. The method used is based on a transdisciplinary approach which involves target communities and authorities in all processes through workshops and site visits. Interventions adopted the concept of ＂one health＂ benefiting of an added value of closer cooperation between human and animal health. This approach was tested with joint interventions between human and animal health, which provided access to health services for unreached communities and saved resource when compared with single sector intervention. Such approaches could be extended to other social services within cross-sector interventions such as the delivery of basic education in nomadic areas. Such a strategy was validated by the communities and authorities and was further transformed into a national programme after a series of six national stakeholders＇ seminars. The cross-sector intervention will provide a minimum package of services （MPS） without compromising the structural services.
文摘Farmer-pastoralist conflicts represent a significant challenge for rural communities and the Tanzanian government.The study objectives were to(i)determine existing forms of conflicts and(ii)identify drivers underlying resource use conflicts.The manuscript is based on a study that adopted a cross-sectional research design whereby data were collected from 373 randomly selected respondents from Kilosa and Kiteto districts,Tanzania,while primary data were collected through interviews,observations and focus group discussions,secondary data were gathered from government reports and newspapers.Quantitative data were analysed using the Statistical Package for the Social Science(SPSS)version 20.0.Descriptive statistical analysis was carried out for quantitative data.Factor analysis was used to extract component factors on drivers and forms of conflicts,whereas content analysis was used to analyse the qualitative data.Generally,study results show that there were three main forms of conflict namely farmers versus pastoralists over village boundaries;farmers versus pastoralists over livestock routes and farmers versus farmers over the land.In addition,four main drivers underlying resource use conflicts were identified namely crop damage by livestock;inefficiency of government officials in taking action to diffuse conflicts;excessively large herds of cattle and corruption.It is therefore recommended that pastoralists should be provided with essential services such as water in order to minimize movement of their livestock herds from their designated villages to other areas in search of water.This would,in the long run,minimise crop damage which has been a major source of conflict.In addition,proper land use planning is recommended to minimize resource use conflicts.
