An average of eight snowfall events occur each year in the eastern Lesotho Highlands.These snowfall events are typically associated with cut-off low(CoLs)systems and mid-latitude cyclones.However,the moisture sources of the snowfall are unclassified and unclear.The Hybrid Single-Particle Lagrangian Integrated Trajectory(HYSPLIT)model,an air mass back trajectory model,has been used to evaluate moisture source waters locally in southern Africa and internationally in China and Europe.This study uses HYSPLIT to determine the source moisture of snow in Lesotho.A list of all 82 snowfall events in Lesotho spanning 2017 to 2022 was compiled using the Snow Report SA Instagram page,including the date and location of snowfall.A 72-hour back trajectory for each snowfall event was initiated for both Afriski and the whole of Lesotho.This amounts to models of moisture source trajectories for 28 and 82 snowfall days,respectively.These air mass pathways are classified according to their frequency per snowfall event,per month in the snow season,per year and for the full period.From this,associated moisture source regions and dominant air mass trajectories were identified.This study reports that the air mass trajectories associated with Afriski and Lesotho as a whole are very similar.The most common pathway of air mass trajectories transporting snow-bearing moisture to Lesotho was an inland trajectory from the northern regions of southern Africa.This pathway makes up 16.6%of all trajectories reported and is associated with the Angola Low,the Congo Air Boundary and the St.Helena High Pressure. 展开更多

Global food demand requires that soils be used intensively for agriculture, but how these soils are managed greatly impacts soil fluxes of carbon dioxide (CO2). Soil management practices can cause carbon to be either sequestered or emitted, with corresponding uncertain influence on atmospheric CO2 concentrations. The situation is further complicated by the lack of CO2 flux measurements for African subsistence farms. For widespread application in remote areas, a simple experimental methodology is desired. As a first step, the present study investigated the use of Bowen Ratio Energy Balance (BREB) instrumentation to measure the energy balance and CO2 fluxes of two contrasting crop management systems, till and no-till, in the lowlands within the mountains of Lesotho. Two BREB micrometeorological systems were established on 100-m by 100-m sites, both planted with maize (Zea mays) but under either conventional (plow, disk-disk) or no-till soil mangement systems. The results demonstrate that with careful maintenance of the instruments by appropriately trained local personnel, the BREB approach offers substantial benefits in measuring real time changes in agroecosystem CO2 flux. The periods where the two treatments could be compared indicated greater CO2 sequestration over the no-till treatments during both the growing and non-growing seasons. 展开更多

Community health workers (CHWs) have long played an important role in the management of complex health problems, especially in resource-poor settings. Although there is a large literature regarding the use of CHWs around the world, there is little detail about how these workers are selected, trained and utilized in the field. Lesotho has one of the highest rates of HIV in the world, with an estimated 25% of the general population infected with the disease;at the same time, there is a significant health human resources shortage in Lesotho with an estimated 60% of health posts left vacant. Community health workers have the potential to play a major role in HIV treatment scale-up in the country, and in 2006, a CWH-based project called 'The Rural Initiative' was started in the remote mountain regions of the country. More than 1000 CHWs were trained and employed through this program between June 2006 and December 2008. This paper will review the CHW program in detail, with a focus on recruitment, training, ongoing supervision and support, and the larger public health implications of the CHW program in Lesotho. It is hoped this program can serve as a practical model for other programs working with or in need of CHWs. 展开更多

Background: Health care professionals at the front line of the COVID-19 pandemic require continued support to ensure not only their well-being, but enhanced care for those infected by the disease. This study aimed to assess the perceptions of health care providers regarding the COVID-19 pandemic in Lesotho. Methodology: A quantitative cross-sectional survey design was used to collect data from 190 healthcare workers who were conveniently sampled from a total of 25 health care facilities and completed structured questionnaires. Data were collected in September 2021 and analyzed using SPSS (vs23). Permission to conduct this study was granted by the relevant authorities. Informed written consent was given by the respondents in writing before they could take part in this study. Results: Respondents had positive views about the COVID-19 pandemic, and they were associated with the level of education. They understood that COVID-19 can affect anyone, including themselves and is not a disease for any particular race. They perceived that they could contract COVID-19, even despite pre-existing conditions, and there was a positive prognosis after contracting COVID-19 if necessary precautions were taken. Furthermore, they knew that the virus was affecting many people worldwide, including the elderly, who were willing to be tested. Respondents felt the testing procedure was rather painful and uncomfortable. The test providers were friendly and not rude, and respondents did not have any preferred gender for them. Respondents were also willing to discuss issues on COVID-19 with families and friends, and they lived close to health care facilities. Conclusions: This study concludes that healthcare professionals at the frontline were mostly nurses, and they had positive perceptions about the COVID-19 pandemic as they were knowledgeable and willing to test for the disease. Test providers were viewed as pleasant and healthcare facilities were accessible. Support for frontline healthcare professionals remains crucial to ensure effective service delivery. More education can be provided to enhance the general views about the COVID-19 to improve uptake of services, not only amongst healthcare professionals but the general public. 展开更多

Russian wheat aphid (Diuraphis noxia) is an international wheat pest and was first recorded in South Africa in 1978 in the Bethlehem area in the Eastern Free State. Le-sotho lies adjacent to one of the largest wheat producing areas in South Africa, the Eastern Free State, where winter wheat and facultative types are cultivated under dry land conditions. Wheat (Triticum aestivum L.) is an important crop adapted to all agro-ecological zones of Lesotho. Russian wheat aphid may have a significant impact on wheat yield. No monitoring or pest control is being done in Lesotho and at this stage there is very little information on the Russian wheat aphid resistance of wheat culti-vars cultivated in Lesotho. In view of this it is important to monitor the distribution of Russian wheat aphid biotypes in Lesotho and determine the level of Russian wheat aphid resistance in local Lesotho wheat cultivars. Two local Lesotho wheat cultivars, Bolane and Makalaote were screened together with South African cultivars Elands, Matlabas, Senqu, PAN3379, PAN3118 and SST387, in the glasshouse against all four known biotypes that occur in South Africa. All these cultivars were also planted in 5 m plots in the field at two localities Leribe and Roma in the lowlands of Lesotho. These cultivars were screened in the field for Russian wheat aphid resistance. The predomi-nant Russian wheat aphid biotypes in these areas were also determined. The Lesotho cultivar, Bolane had resistance against RWASA2 in the glasshouse, while Makalaote did not have any Russian wheat aphid resistance in either the glasshouse or field screenings. To contribute to food security an increasing wheat yield potential is a high priority. Russian wheat aphid has been included in the list of important international cereal pests. Russian wheat aphid adapts to changing environments and taking their ecology, distribution, virulence patterns, and variability into account is important in minimizing the gap between actual and attainable yields. Current management prac-tices for winter wheat in South Africa include the use of resistant cultivars, which is the most economical management strategy for Russian wheat aphid. Introducing Russian wheat aphid resistant cultivars in Lesotho will improve overall yield and as a result food security. This will also result in lower Russian wheat aphid pest pressure in the adjacent wheat production areas in the Eastern Free State, South Africa. 展开更多

Bathymetry survey records of the Muela Reservoir in norther Lesotho were obtained from the Lesotho Highlands Development Authority(LHDA)with the aim of identifying reservoir storage apacity loss due to sediment deposition,between 1985 and 2015.For this purpose,data from eight surveys completed between 1985 and January 2015 were analyzed to quantify bathymetric change between each survey.Four interpolation methods(inverse distance weighting Kriging,natural neighbor,and spline),were used to create digital terrain models from each survey data-set.In addition,a triangulated irregular network(TIN)surface was created from each data-set.The average reservoir storage capacity loss of 15,400 m^(3)/year was determined across the whole per iod between 1985 and early 2015,based on Kriging.Whilst the results indicate high inter-annual variability in the rate of reservoir capacity reduction,consideration of errors in the surveying and reservoir volumetric calculation methods suggest that rates of reservoir volume reduction can vary between 11,400 m/year and 18,200 m/year. 展开更多

Tourism Climatic Indices(TCIs)are widely used in the global North to quantify the climatic suitability of a destination for tourism.Only one such study has been conducted in southern Africa to date.It is in a chronic shortage of research on tourism and climate change in the southern hemisphere.This study presents the application of the TCI in Lesotho,calculated for the eastern Lesotho Highlands.The region has an emerging tourism sector,which primarily comprises outdoor activities.These include hiking,horse-riding,music festivals,mountain biking,cultural visits,sightseeing,and at the Afriski lodge,skiing and snowboarding.These activities are reliant on climatic conditions that are conducive to the activity taking place,prolonged periods outdoors,and tourist satisfaction of the activity.Climate is a major determinant of both the length of season for these activities and the timing of peak tourist arrivals.Rising temperatures and changes in relative humidity and precipitation pose real threats to hiking,sightseeing and snow tourism at Afriski.The reliance of tourism in the region on specific climatic conditions for successful tourism prompted the use of the TCI.TCI results classify the eastern Lesotho Highlands as having‘good'climatic conditions with an overall TCI score of 64 for the period 2012-2017.Monthly TCI scores for the eastern Lesotho reveal a bimodal-shoulder,meaning the peak climatic conditions are in the regional summer months(December to February).This conflicts with the peak tourist seasons of summer and winter,which align with South African school holidays,and the timing of the most profitable tourism activity(skiing)which occurs during the winter months of June,July and August.Lesotho is landlocked by South Africa.TCI analysis for South Africa reveals more suitable climatic conditions for tourism than Lesotho,with significantly higher scores of 80-89. 展开更多

Reflecting profiles of the chequered existence of migrant mine laborers, Basotho miners' chants belong to the category of occupational folklore. As such they provide a unique window for debate about the ethics of place. Place actually amounts to three places--home, which the worker leaves behind; mine compound, the workplace in the foreign country; and then the journey in-between, connecting home and work. In the poet's creative consciousness, the instability of place raises ethical responses--to home, which is often romanticized; to work, which is often dramatized and ridiculed; and to the journey, which is animated. Ethical questions about loss, longing, danger feelings of guilt, and the threat of death are implied. The genre as aesthetic verbal expression, allows space for negotiating degrees of acceptance of predicament and conciliation. A historic-economic, socio-cultural, and genre-specific approach enables a concise unpacking of how aspects of the ethics of place are brought together and rearranged by this oral poetry--the difela--that developed from the migrant mine labor system 展开更多
