KAZNET: An Open-Source, Micro-Tasking Platform for Remote Locations

Field surveys are the workhorse of social and environmental research, but conventional collection through monitors or enumerators are cost prohibitive in many remote or otherwise difficult settings, which can lead to a poor understanding of those environments and an underrepresentation of the people living in them. In such cases, micro-tasking can offer a promising alternative. By activating in-situ data collectors, micro-tasking avoids many of the large expenses related to conventional field survey processes. In addition to relaxing resource constraints, crowd-sourcing can be flexible and employ data quality protocols unheard-of for conventional methods. This study assesses the potential of using micro-tasking to monitor socioeconomic and environmental indicators in remote settings using a new platform called KAZNET. KAZNET leverages the network of people with smartphones, which are becoming ubiquitous even in the remote rural settings, to execute both long-term and short-term data collection activities, with flexibility to adjust or add tasks in real-time. It also allows for multiple projects, requiring different data types, to be rolled out in the same platform simultaneously. For the data-collector, KAZNET is effectively a wrapper for the commonly used and open source, Open Data Kit (ODK) software, which specializes in offline data collection. A web interface allows administrators to calibrate, deploy, and validate tasks performed by contributors. KAZNET has been used in several projects to collect data in remote pastoral regions of East Africa since its inception in 2017. KAZNET has shown to be effective for collecting high frequency and repeated measures from markets, households and rangelands in remote regions at relatively low cost compared to traditional survey methods. While the successes of micro-tasking are promising, there are clear trade-offs and complementarities between micro-tasking and standard surveys methods, which researchers and practitioners need to consider when implementing either approach.

The impact of a kānuka silvopastoral system on surface runoff and sediment and nutrient losses in New Zealand hill country

New Zealand hill country is a pastoral region that has high levels of surface runoff and sediment and nutrient losses. Silvopastoralism has potential to mitigate these losses via the interaction of trees with the soil, pasture and livestock. This study compares surface runoff and sediment and nutrient losses (nitrogen and phosphorus) in pasture plots with and without Kunzea robusta (kānuka) trees and investigates the reasons for the variation in these losses between kānuka pasture and open pasture. Annual surface runoff was 54.0 mm in kānuka pasture and 7.6 mm in open pasture despite kānuka pasture having improved soil conditions (in terms of porosity, organic matter and soil fertility). Kānuka pasture had species indicative of good pasture condition even though the plots had significantly less standing grass biomass. This was most likely due to livestock preferentially grazing the pasture under kānuka which led to less attenuation of surface runoff. Sediment and nutrient losses were 10–100 times greater in kānuka pasture, mainly due to the increase in surface runoff, but also because of livestock concentrating nutrients under the trees through excreta deposition. These results are contrary to past silvopastoral research and highlights that an extreme choice between shaded areas of good pasture condition and unshaded areas of poor pasture condition within a pastoral hillside can lead to negative consequences in terms of surface runoff and contaminant losses because of livestock interactions. More research is required to understand these processes in other hill country farms and grazing conditions, and explore mitigation options.

Magnitude and factors associated with intimate partner violence against pregnant women in Ethiopia: a multilevel analysis of 2016 Ethiopian demographic and health survey

BackgroundIntimate partner violence (IPV) is defined as acts of physical aggression, sexual coercion, psychological/emotional abuse, or controlling behaviors by a current or former partner or spouse. IPV has a special concern for pregnant women since it leads to higher rates of miscarriage, several complications including adverse birth outcomes. So far, the effect of contextual factors on IPV was largely overlooked. Therefore, this study aimed to assess the magnitude and factors associated with IPV among pregnant women in Ethiopia.MethodData from the 2016 Ethiopian Demographic and Health Survey was used for this study. A total of 4167 (weighted sample) pregnant women were included in the analysis. The multi-level logistic regression model was fitted to identify factors associated with IPV. Finally, the adjusted odds ratio (AOR) with 95% CI and random effects for the multilevel logistic regression model was reported.ResultsIn this study, the overall magnitude of IPV among pregnant women was 28.74 (95% CI 27.38, 30.13) with emotional violence being the most common (24.09%) type. In the multi-level analysis, women with no education (AOR = 2.07; 95%CI 1.23, 3.48), primary education (AOR = 2.04; 95%CI:1.24, 3.38), and secondary education (AOR = 1.53; 95%CI:1.29.2.62), women from households with poorest (AOR = 1.72; 95%CI: 1.16, 2.56), poorer (AOR = 1.62;95% CI:1.09, 2.41), middle (AOR = 1.74;95%CI:1.17, 2.56), and richer (AOR = 1.58;95%CI: 1.08, 2.33) wealth index, women aged 35–39 years (AOR = 1.28;95%CI:1.01, 1.63) and 40–49 years (AOR = 1.78;95%CI:1.28, 2.45) and those from pastoral (AOR = 1.47;95%CI:1.04, 1.93) and agrarian regions (AOR = 1.32;95%CI 1.02, 1.88) had a higher likelihood of having IPV. Of the partner-related factors, women with husbands who drink alcohol (AOR = 2.94; 95%CI: 2.36, 3.42) and secondary educational level (AOR = 1.47; 95%CI 1.02, 2.12) had higher odds of experiencing IPV during pregnancy.ConclusionIntimate partner violence during pregnancy is a public health problem in Ethiopia. Therefore, improving the educational status of women and their husbands, improving the economic capacity of women, and promoting the healthy behavior of husbands by reducing the alcohol consumption in those agrarian and pastoral regions of Ethiopia is vital to reduce the magnitude of IPV.

Supply and marketing of small ruminants in N’djamena’s Livestock Markets, Chad

The study aimed to assess the supply and marketing of small ruminants in the markets of N’Djamena city. It was carried out by random survey of 42 traders distributed in 6 small ruminant markets in N’Djamena city. The results showed that the traders were 37.21±7.74 years old. They had little education (69%) with 11 years of experience. All the small ruminant traders originated from pastoral regions where breeding represented a dominant activity. The most traded species were sheep (90.5%) and goats (9.5%). Diguel’s markets ensured the supply of animals to other markets. Animals are transported to other markets by minibuses (57.1%) and vans (33.3%), at an average price of 1,100 CFA francs per head. The expenses incurred were around 2,376 CFA francs / head / day. Average selling price was 26,577.33 ± 3,801.08 CFA francs for sheep and 19,583.33± 1,878.84 CFA francs for goats. With three (3) sheep and two (2) goats sold per day, the average net margin achieved was 7,752 CFA francs and 6,840 CFA francs for sheep and goats, respectively. The organization of stakeholders and the development of livestock market infrastructure will allow a better supply of small ruminants to the markets.

Prevalence, Risk Factors for Exposure, and Socio-Economic Impact of Peste Des Petits Ruminants in Karenga District, Karamoja Region, Uganda.

Peste des petits ruminants (PPR), a disease caused by small ruminant morbillivirus (SRM), is highly contagious with high morbidity and mortality. Controlling PPR requires a proper understanding of the epidemiological dynamics and impact of the disease in a range of geographical areas and management systems. Karenga district, located in the pastoral region of Karamoja in northeastern Uganda, and in the vicinity of Kidepo Valley National Park, is characterised by free cross-border (South Sudan and Kenya) livestock trade, communal grazing, and transhumance. This study was conducted from November through December 2020 to determine the seroprevalence of anti-SRM antibodies, the risk factors associated with the occurrence, and the socio-economic impact of PPR in Karenga. A total of 22 kraals were randomly selected from all administrative units, and 684 small ruminants (sheep = 115, goats = 569) were selected for serum collection using systematic random sampling. Exposure to SRM was determined using a competitive enzyme-linked immunosorbent assay. The overall true seroprevalence of SRM antibodies was high, 51.4 (95% confidence interval [CI] 45–52.6). Multivariate logistic regression for risk factors showed that seroprevalence varied significantly by location (26.8% to 87.8%, odds ratio (OR) ≤ 14.5). The odds of exposure to SRM were higher in sheep (73.9%) than in goats (43.8%) (OR = 1.7, p = 0.08), and seropositivity was higher in animals greater than two years old (65.5%; OR = 11.1, p < 0.001), or those one to two years old (24.7%; OR = 1.6, p = 0.2), compared to small ruminants less than one year old (16.1%). Using participatory epidemiology approaches (semi-structured interviews, clinical examinations, pairwise ranking, proportional piling, impact matrix scoring) with 15 key informants and 22 focus groups of pastoralists, PPR was the second most important small ruminant disease: relative morbidity 14%, relative mortality 9%, and case fatality rate 78%, and impacted productivity mainly in terms of treatment costs, mortality, marketability, and conflicts. These findings provide evidence to support the implementation of disease surveillance and control strategies to mitigate the impact of PPR in Karamoja and other pastoral areas in eastern Africa.

Climate Change-Induced Drought Impacts, Adaptation and Mitigation Measures in Semi-Arid Pastoral and Agricultural Watersheds

Periodic drought is a major challenge in drought-prone areas of South Asia. A sample survey of farmers (n = 400) from South Asia was conducted to study the farmers’ perception about drought impacts on their socio-economic status, agro-biodiversity, and adaptation besides public institutions’ drought mitigation measures. The results revealed reduced surface and groundwater availability, soil degradation, partial or complete crop failure, increased agricultural fallows and wastelands, biodiversity loss, decrease in agricultural yields, pasture lands, and livestock in drought-impacted South Asia. About 16–26% of the farmers perceived a reduction in the agricultural area and production of commercial crops and millets in drought-prone areas, while changes in the cropping of pulses, oilseeds, horticultural, and fodder crops were minimal. About 57–92% of respondents showed a reduction in the consumption of fruits, vegetables, dairy products, and fish. Unemployment, migration, reduced farm income, and malnutrition were major socio-economic impacts among respondents (38–46%). Despite sufficient public support as a mitigation strategy, the farmers had poor participation (8–65%) for agri-information and adaptation (7–36%) against drought impacts. Hence, researchers, extension agents, and policymakers must develop efficient ‘participatory-mode’ drought adaptation and mitigation policies in watershed-based semi-arid pastoral and agricultural regions of South Asia and similar agro-ecologies across the globe.

Improving herders’ income through alpine grassland husbandry on Qinghai-Tibetan Plateau

Promoting sustainability of ecosystems and economic development is a dual national objective in China, as well as one of the sustainable development goals (SDGs) of the United Nations. The Three-River Headwaters Region, where a National Park initiative has been initiated in the pastoral region of the Qinghai-Tibetan Plateau, is one of the key pilot projects in China with sustainability targets for 2025 and 2035. This paper assesses the possibility of achieving established targets for the proportion of cultivated to available grassland. These targets consider both ecosystem protection and herders’ livelihoods. An income simulation model was first developed to estimate the percentage of cultivated grassland area necessary from the natural grasslands to achieve the target income. The model was developed using income and livestock data from the annual yearbook for 2018, then applied to estimate conditions for three counties in the eastern region. Presently the rangelands are seriously overgrazed with income just reaching above the poverty level. If livestock were decreased to a theoretical carrying capacity level, income would decrease to lower than the poverty level, even considering a livestock feeding system to achieve higher production levels. Under these circumstances, in order to reach income targets in 2025, one option centered on income production from livestock requires 5% of grasslands to be cultivated to produce forage for livestock. However, achieving income targets in 2035 will become very difficult because the needed proportion was estimated to increase to 14%. An alternative was to transport extra forage from the agriculture region of eastern Qinghai province. The local government should consider these two options to improve herders’ income along with maintaining the traditional nomadic culture and sustainable ecosystems. The approach used to develop and apply this model could be applied to predict income changes accompanying future climate scenarios and to propose policies aimed at sustainability of ecosystems and economies for grasslands worldwide.

Integrating satellite images and topographic data for mapping seasonal grazing management units in pastoral landscapes of eastern Africa

We present a framework for mapping grazing management units in extensive pastoral landscapes. Mapping such units from remote sensing, particularly in the pastoral landscapes of East Africa, is usually hampered by high cost of field data collection and by the fact that the relationship between rangeland ecological characteristics and rangeland use for adaptive grazing management by mobile pastoralists is context specific and reflects complex socio-ecological interactions. We propose, therefore, a flexible framework that combines topographic descriptors with rangeland greenness and phenology indicators derived by remote sensing imagery to derive thematic classes that users can query, according to their requirements, to produce grazing management units. The framework is illustrated for an extensive pastoral region in Southern Ethiopia. The thematic classes generated were statistically compared with Plant Functional Types (PFTs) classes obtained by interpretation of GPS-tagged photos, showing a highly significant relationship (Chi-Square test, χ2 = 5971.4, p = 0.0001). Then, the same classes were further classified into grazing management units by integrating information about rangeland seasonal use and accessibility from pastoral communities. This approach could support the definition of adaptive community-based rangeland management strategies by combining ecologically meaningful maps derived by satellite indicators with local knowledge about rangeland use and accessibility.

Difference in authenticity perception of old towns among China’s various cultural regions

PurposeRegarding research on authenticity perception, this paper aims to pose the following questions: In different cultural regions, what are the different authenticity elements of old towns from a tourist perspective? What is the difference in authenticity perception in different cultural regions? How does the authenticity perception of old towns change in the tourismification process?Design/methodology/approachCombining eight cultural regions in China, this study focuses on 155 old towns to discuss the differences between authenticity perception of various old towns in different cultural regions and how the interactions between tourists and local places influence the perception of authenticity, with 11,387 user-generated photographs applied to interpret authenticity perception.FindingsThe study shows that the authenticity perceived by tourists varies greatly between farming and pastoral cultural regions; after authenticity loss, old towns with a long history of tourismification regain authenticity in tourists’ perception.Originality/valueThe findings could serve as a reference for tourism development and authenticity protection of old towns. Furthermore, the study explores a creative research method and theoretical framework for regional authenticity studies, which is significant in a global context. In the process of globalization, the implications of this study, including differences in authenticity perception within various cultural regions, will also be significant globally.

A Long-Term Ecological Vulnerability Analysis of the Tibetan Region of Natural Conditions and Ecological Protection Programs

The combined impacts of drastic natural environment change and increasing human interference are making the uncertainty of the Tibetan Plateau’s ecological vulnerability the world’s largest. In this study, an ecological vulnerability index (EVI) of Tibet in the core area of the Tibetan Plateau was assessed using a selected set of ecological, social, and economic indicators and using a spatial principal component analysis (SPCA) to calculate their weights. The data included Landsat images and socio-economic data from 1990 to 2015 in five-year intervals. The results showed that the total EVI remained at a high vulnerability level, with drastic fluctuation from 1990 to 2000 (a peak in 1995, when there was a sudden increase in light vulnerability, which moved to extreme vulnerability in the next period), and minor fluctuations after 2000, gradually increasing from southeast to northwest. In addition, the spatial analysis showed a distinct positive correlation between the EVI and grassland area (0.33), land use degree (0.15), NDVI (0.14), livestock husbandry output, and a negative correlation in terms of desertification area. The artificial afforestation program (AAP) had a positive significant correlation with NDVI (R2 = 0.88), preventing the environment from becoming more vulnerable. The results provide practical information and suggestions for planners to improve the land use degree in urban areas and the vegetation coverage in pastoral regions of the Tibetan Plateau based on the spatial–temporal heterogeneity patterns of the EVI of Tibet.

Hypertension among Mongolian adults in China: A cross-sectional study of prevalence, awareness, treatment, control, and related factors: Hypertension among Mongolian adults in China.

The objectives of the study were to comprehend the prevalence of hypertension (HTN) and prehypertension (PHT), awareness, treatment, and control of HTN and its distribution in urban, agricultural, pastoral, and semi‐agricultural/semi‐pastoral areas, and to explore the related factors of HTN among Mongolian adults in China. From August 2018 to August 2020, a multi‐stage stratified cluster random sampling method was conducted to investigate the prevalence of HTN among Mongolian adults aged ≥18 years living in China (n = 2558). Inclusion criteria for HTN were systolic blood pressure ≥ 140 mm Hg and/or diastolic blood pressure ≥ 90 mm Hg and/or had hypertensive history and/or taking antihypertensive drugs for HTN. The prevalence rates of HTN and PHT were 44.77% and 32.03%, respectively. The prevalence rates of PHT in urban, agricultural, pastoral, and semi‐agricultural/semi‐pastoral areas were 34.93%, 34.73%, 26.03%, and 33.44%, respectively, and the prevalence rates of HTN were 35.97%, 40.15%, 49.68%, and 48.07%, respectively. The awareness, treatment and control rates of HTN were 66.48%, 58.93%, and 16.48%, respectively. In this survey, the overweight, obesity, and central obesity rates were 34.30%, 30.67%, and 58.08%, respectively. Compared with Chinese adults ≥18 years, the prevalence rate of HTN among Mongolian adults in China aged ≥ 18 years was relatively high; the prevalence rate of PHT and HTN awareness, treatment, and control rates were similar. The prevalence of HTN and the rates of obesity and central obesity were higher in pastoral regions than in the other three types of regions, and the rate of overweight was highest in agricultural regions.

Integrated human-animal sero-surveillance of Brucellosis in the pastoral Afar and Somali regions of Ethiopia

BackgroundBrucellosis is widespread in Ethiopia with variable reported prevalence depending on the geographical area, husbandry practices and animal species. However, there is limited information on the disease prevalence amongst pastoral communities, whose life is intricately linked with their livestock.MethodologyWe conducted an integrated human-animal brucellosis sero-surveillance study in two adjacent pastoral regions, Afar and Somali region (SRS). This cross-sectional study included 13 woredas (districts) and 650 households. Blood samples were collected from people and livestock species (cattle, camel, goats and sheep). Sera were analyzed with C-ELISA for camels and shoats (sheep and goats), with I-ELISA for cattle and IgG ELISA for humans. Descriptive and inferential statistics analyses were performed.ResultsA total of 5469 sera were tested by ELISA. Prevalence of livestock was 9.0% in Afar and 8.6% in SRS (ranging from 0.6 to 20.2% at woreda level). In humans, prevalence was 48.3% in Afar and 34.9% in SRS (ranging from 0.0 to 74.5% at woreda level). 68.4% of all households in Afar and 57.5% of households in SRS had at least one animal reactor. Overall, 4.1% of animals had a history of abortion. The proportion of animals with abortion history was higher in seropositive animals than in seronegative animals. Risk factor analysis showed that female animals were significantly at higher risk of being reactors (p = 0.013). Among the species, cattle had the least risk of being reactors (p = 0.014). In humans, there was a clear regional association of disease prevalence (p = 0.002). The older the people, the highest the odds of being seropositive.ConclusionBrucellosis is widespread in humans and animals in pastoral communities of Afar and SRS with the existence of geographical hotspots. No clear association was seen between human and particular livestock species prevalence, hence there was no indication as whether B. abortus or B. melitensis are circulating in these areas, which warrants further molecular research prior to embarking on a national control programs. Such programs will need to be tailored to the pastoral context.

Violent conflict exacerbated drought-related food insecurity between 2009 and 2019 in sub-Saharan Africa.

Conflict, drought and locusts are leading concerns for African food security but the relative importance and spatiotemporal scale of crises resulting from each hazard is poorly characterized. Here we use continuous, subnational data to demonstrate that the rise of food insecurity across sub-Saharan Africa that began in 2014 is attributable to an increase in violent conflict, particularly in South Sudan and Nigeria. Although drought remains a leading trigger of food crises, the prevalence of drought-related crises did not increase from 2009 to 2018. When exposed to drought, pastoralists experienced more widespread, severe and long-lasting food crises than people living in agricultural zones. Food insecurity remained elevated in pastoral regions for 2 years following a drought, while agricultural regions returned to pre-drought food-security levels in ~12 months. The few confirmed famines during the 2009-2018 period coincided with both conflict and drought, while locusts had little effect on food security during this period.

Spatiotemporal evaluation of alpine pastoral ecosystem health by using the Basic-Pressure-State-Response Framework: A case study of the Gannan region, northwest China

Ecosystem health is the goal of eco-environmental management, and its assessment is necessary for improving regional ecological environments and promoting regional sustainable development. However, previous studies on regional ecosystem health assessment have mainly concentrated on rapidly developing urbanized areas, with very few having been conducted on alpine pastoral regions. Taking the Gannan alpine pastoral region of China as the study area, and based on remote-sensing and GIS technologies, we used entropy methods to calculate the relative weights of several indicators to quantify the uncertainty in the data processing so that the accuracy of the results of the ecosystem health evaluation could be improved. In this study, a new basic-pressure-state-response assessment framework for alpine pastoral ecosystem health assessment is proposed, based on the pressure-state-response. It was found that the levels of ecosystem health of the Gannan pastoral had a spatial distribution pattern that decreased from southwest to northeast, from 2000 to 2015. Notably, the areas of the well and weak health showed a decreasing trend, with more regions tending toward ordinary levels. Among all the assessing indicators, the average value of the pressure indicator was the greatest, with the basic indicator value being the lowest. Our assessment results could be used as a guide for eco-environment managers tasked with taking effective measures to improve the status of the ecosystem health in alpine pastoral regions.

Prevalence of Intestinal Parasites and Associated Risk Factors in Chepang Community of Saktikhor Area, Chitwan, Nepal

Abstract: Objective: Pathogenic species of protozoa and helminth cause intestinal parasitosis, which continues to be a significant community well-being issue in many regions of the world, especially in pastoral regions of developing countries like Nepal. The study focused on determining the prevalence of intestinal parasitic infections and the associated risk factors among the people of the Chepang community of the Saktikhor area in the Chitwan district. Materials and Methods: A transversal study was conducted between May 2017 and October 2017, with a total of 125 participants. The fecal samples were examined using a wet media (saline media, iodine preparation), concentration and sucrose flotation method. The association between risk factors and parasitic prevalence was evaluated using the Pearson’s chi-square test. Results: The general prevalence of intestinal parasite infection was 52%. Infections with soil-borne helminth were more common than those with cestodes and protozoa. Common intestinal parasites included Ascaris lumbricoides (69.23%), Trichuris trichiura (9.23%), Hookworm (7.69%), Strongyloides stercoralis (4.62%), Hymenolepis nana (6.15%), Taenia sp. (6.15%), and Entamoeba coli (9.23%). High prevalence of infection was observed among male (53.96% ) participants and those aged over 20 years (69.44%). Pearson's chi-square test revealed a substantial relationship between prevalence of parasite and age group (P=0.0452), hand washing material (P&lt;0.001) and preference for defecation site (P&lt;0.001). Conclusion: Hence, a heavy occurrence of intestinal parasites within the Chepang community is particularly evident. There is a need for increased emphasis on intrusion, which can be achieved by improving personal hygiene and sanitation of participants and constructing proper sanitary toilets to prevent the spread of parasitic infections.

Long-term dynamics of nitrogen flow in a typical agricultural and pastoral region on the Qinghai-Tibet Plateau and its optimization strategy

Nitrogen (N) plays a central role in livestock development and food production in agricultural and pastoral regions, while its flow and loss can affect environmental quality, biodiversity and human health. A comprehensive understanding of the sources, patterns and drivers of N flow helps to alleviate its negative effects and promote sustainable management. We developed a county-scale N flow model to quantitatively analyze the N use efficiency (NUE), N losses and their driving forces in the food production and consumption system (FCPS) on the Qinghai-Tibet Plateau (QTP). More sustainable N utilization was further investigated through scenario analyses. Our results revealed that N fluxes doubled from 1998 to 2018 to maintain the growing demands for human food production and consumption in Ledu County, which was related to the increasing N losses to the atmosphere and water environment. The surging N fluxes greatly changed the N distribution pattern, resulting in a relatively low NUE (mean value: 29.41%) in the crop-production subsystem (CPS) and a relatively high NUE (mean value: 23.50%) in the livestock-breeding subsystem (LBS). The CPS contributed the most to the N losses. The urban population, animal-derived consumption, crop planting structure, imported fodder and N fertilizer application level were closely associated with N losses. The scenario analysis indicated that combined reasonable changes in planting structure, precision animal feeding, fertilizer management, diets and conversion of cropland into pasture could reduce N losses in 2030 to 5%–61% of Business as usual level. Our results highlighted the strong anthropogenic impact on the N flow of food production and consumption and suggested a sustainable N flow management strategy to harmonize the relationship between N flow and anthropogenically driven factors on the QTP.

Female Dancers in Ancient Tamil Tradition Rise and Fall – From 200 BC to 300 AD

The history of origin and development of dance and music tradition of Tamils in the ancient period can be traced merely from Cangam literature-Ettuthokai and Patthuppattu . The period of this literature is considered from 200 BC to later period of 300 AD or early part of the 4th century AD. There is no other evidences excavated about the ancient dancers from archeological sources. K.A Neelakanda Sastry, historian of Tamil Nadu used Ettuthokai and Pattuppattu as a significant source to write the ancient history of Tamil Nadu, as evidences for the history because of non availability of archeological evidences at that time.&#x0D; Ancient Dance tradition of Tamils was originated from the indigenous dance tradition of Tamils, lived in Kurinji (hill Countryand nearby lands) Mullai (pastoral region) Marutham (rivarbanks) Neithal (Coastal Area) and Palai (desert).Cangam literature shows that the tribal people of these lands performed ritual dances . These performances are the roots to the origin of Tamil dances , after that, with the establishment of stateformation of Tamil Nadu skill dancers and minstrels developed new forms of dances and music, in later period these dances were being called as Vettiyal.&#x0D; Dancers and minstrels were lived under the patronage of the kings of Tamil Nadu and loved by the kings. These performers praised the kings’ victory, their patronization and nvolved in their patrons’ family life also.&#x0D; Ritual dances were performed in Cult spots and war front.The literature shows that some of these performances have been developed as classical dances.&#x0D; Nowadays there is an opinion about Baratha natiyam that it was originated from sanskrit sources. But the ancient history of this dance tradition clearly shows that Baratha natiam was originated from the ancient dance tradition of Tamil Nadu.&#x0D; This study focuses the origin and development of dance tradition of ancient Tamils and the performances of female dancers of thisera, and flourished life of the the mas well asin the decline of the kings of three monarchy and other patrons how the dancers lost their wealthy life in the period.

Times of debt: heterochrony and bank loans in rural Mongolia

AbstractRecent scholarship in economic anthropology examines how the intersection of multiple forms of temporality shapes the time of debt relations. This article builds on and refines these approaches by analysing debt as a social relation that ‘folds’ the time of other relations within itself. It does so through deploying the concept of the ‘fold’ drawn from continental philosophy and anthropological literature on personhood. This approach provides a novel way of illuminating and reflecting upon a temporal tension at the heart of debt relations, in which the timely performance of debtor‐creditor relations is contingent on the harnessing of temporalities formally outside their scope. This argument is made in relation to an ethnographic study of malchny zeel (the ‘herder's loan’) issued by commercial banks in a pastoral region of Mongolia.

Informal institutions and grassland protection: Empirical evidence from pastoral regions in China

Grassland has experienced continuous degradation, resulting in serious ecosystem services loss and unsustainable grazing production. Previous studies have identified the impact of formal environmental institutions or policies on grassland protection. But, little evidence of the effectiveness of informal institutions has been found. Using village grassroots governance as a proxy for informal institutions, this study empirically identifies the effects of informal institutions on grassland quality improvement. Results show that the presence of informal governance leads to improvement in grassland quality. Moreover, these positive effects are found to be more significant when informal governance is in a written form and penalties occur as a consequence of violations. Further investigations reveal that the effectiveness of informal governance is mediated by village size, villager income, household-level compensation from government conservation programs, and grassland property right privatisation. The findings offer new insights into the positive role played by informal institutions in natural resource management and would assist existing policy instruments in grassland protection.

Protein and Microbial Biomarkers in Sputum Discern Acute and Latent Tuberculosis in Investigation of Pastoral Ethiopian Cohort.

Differential diagnosis of tuberculosis (TB) and latent TB infection (LTBI) remains a public health priority in high TB burden countries. Pulmonary TB is diagnosed by sputum smear microscopy, chest X-rays, and PCR tests for distinct Mycobacterium tuberculosis (Mtb) genes. Clinical tests to diagnose LTBI rely on immune cell stimulation in blood plasma with TB-specific antigens followed by measurements of interferon-γ concentrations. The latter is an important cytokine for cellular immune responses against Mtb in infected lung tissues. Sputum smear microscopy and chest X-rays are not sufficiently sensitive while both PCR and interferon-γ release assays are expensive. Alternative biomarkers for the development of diagnostic tests to discern TB disease states are desirable. This study’s objective was to discover sputum diagnostic biomarker candidates from the analysis of samples from 161 human subjects including TB patients, individuals with LTBI, negative community controls (NCC) from the province South Omo, a pastoral region in Ethiopia. We analyzed 16S rRNA gene-based bacterial taxonomies and proteomic profiles. The sputum microbiota did not reveal statistically significant differences in α-diversity comparing the cohorts. The genus Mycobacterium, representing Mtb, was only identified for the TB group which also featured reduced abundance of the genus Rothia in comparison with the LTBI and NCC groups. Rothia is a respiratory tract commensal and may be sensitive to the inflammatory milieu generated by infection with Mtb. Proteomic data supported innate immune responses against the pathogen in subjects with pulmonary TB. Ferritin, an iron storage protein released by damaged host cells, was markedly increased in abundance in TB sputum compared to the LTBI and NCC groups, along with the α-1-acid glycoproteins ORM1 and ORM2. These proteins are acute phase reactants and inhibit excessive neutrophil activation. Proteomic data highlight the effector roles of neutrophils in the anti-Mtb response which was not observed for LTBI cases. Less abundant in the sputum of the LTBI group, compared to the NCC group, were two immunomodulatory proteins, mitochondrial TSPO and the extracellular ribonuclease T2. If validated, these proteins are of interest as new biomarkers for diagnosis of LTBI.
