Public rituals of buffalo sacrifice have a prominent place in the political history of eastern India. They were productive activities in agrarian livelihoods, stages for intercommunal politics, unifying spectacles for regional kings, and justifications for colonial military interventions. While their historical scale is much reduced today, in parts of southern Odisha, they remain important political events. Drawing on historical research and long-term ethnographic fieldwork in Odisha’s Kandhamal Hills, this article examines how public rituals of sacrifice form a site of commensuration: a space where interlocal relations of mutuality and difference are temporarily made visible, and where value is defined in the presence of diverse audiences. By focusing on one specific ritual event, I show how these “sacrificial publics” are structured around the tensions of sovereignty (togetherness and transgression) and have long been spaces where different kinds of sovereign power have become legible. Historicizing an enduring sacrificial politics at India’s upland margins, I outline a distinctly anthropological concept of sovereignty—one that reflects the ways human relationships are made commensurable in lasting political formations, sustained through interlocal and intercommunal patterns of recognition.

Cholera is one of the major public health problems in the state of Odisha, India since centuries. The current paper is a comprehensive report on epidemiology of cholera in Odisha, which was documented from 1993. PubMed and Web of Knowledge were searched for publications reporting cholera in Odisha during the period 1993–2015. The search was performed using the keywords ‘Odisha’ and/or ‘Orissa’ and ‘Cholera’. In addition, manual search was undertaken to find out relevant papers. During the study period, a total of 37 cholera outbreaks were reported with an average of >1.5 cholera outbreaks per year and case fatality ratio was 0.3%. Vibrio cholerae O1 Ogawa serotype was the major causative agent in most of the cholera cases. The recent studies demonstrated the prevalence of V. cholerae O1, El Tor variants carrying ctxB1, ctxB7 and Haitian variant tcpA allele associated with polymyxin B sensitivity and these variants are replacing the proto type El Tor. The first report of variant ctxB7 in Odisha during super-cyclone 1999 predicted its emergence and subsequent spread causing cholera outbreaks. The prevalence of multidrug-resistant V. cholerae at different time periods created alarming situation. The efficacy trial of oral cholera vaccine (OCV, Shanchol) in a public health set-up in Odisha has shown encouraging results which should be deployed for community level vaccination among the vulnerable population. This paper has taken an effort to disseminate the valuable information of epidemiology of cholera that will influence the policy-makers and epidemiologists for constant surveillance in other parts of Odisha, India and around the globe.

Sacred forests are small patches of forest that are preserved and protected from human exploitation. Although they are identified primarily for spiritual or religious purposes, their contribution to biodiversity conservation has been widely debated. Sacred sites are known to harbour greater biodiversity compared to exploited forests, but the patterns are not well known. We studied tree diversity in a remote forested location in eastern India where sacred forests and reserve forests used by people are present. Tree data from eight sacred forest sites and nine reserve forest sites showed that species richness was significantly greater in sacred forests; species diversity and evenness tended to be greater, but these were not statistically significant. Basal area (a measure of aboveground biomass) was significantly greater, mainly due to the greater density of large trees. There were significant departures from the theoretical expectation of stem size density distributions under pure asymmetric competition for both land tenures, which indicated that extraneous mortality increased death rates of large trees under both regimes, but sacred forests had a greater range of stem sizes. Our results suggest that sacred forests can contribute to biodiversity conservation by preserving greater tree diversity than forests subject to human use.

Entomological indicators such as vector density, distribution, biology and bionomics and their vectorial attributes are important parameters for measuring the pattern and intensity of malaria transmission. Although published articles provide evidence for the existence of associations between entomological indices and malaria transmission dynamics, none of them is able to establish a strong correlation. In order to address this issue, the present study aims to assess how malaria transmission is influenced and can be predicted by local major vector dynamics. We carried out an entomological assessment of major Anopheline vector abundance, habit/habitat, resting and feeding behavior, infectivity rates, and other entomological parameters. Results suggest that malaria transmission was correlated with a vector control intervention and non-intervention scenario in a high endemic region of Kalahandi district of Odisha, India. Amongst all indices, infective anthropophagic vectors established a strong positive correlation with malaria morbidity in comparison to infective or anthropophagic vector species during both the study periods. Though other entomological parameters influenced the transmission intensity, little quantifiable association was detected among study sites. This study provides strong baseline evidence of an association between entomological indices and malaria transmission dynamics, which could be used as an early warning system for outbreak prediction.

Cotton is an important source of income for smallholder farmers in India, usually grown very intensively. To counteract negative impacts of cotton cultivation in India, such as environmental degradation and financial dependency due to high input costs, organic cotton cultivation is being promoted by non-governmental organizations in the country. This study examines how the conversion to organic cotton cultivation influences the livelihood of smallholder farmers in rural India. Interviews with organic farmers were conducted in Odisha, India, complemented by expert interviews and observations in the field. Results show that farmers profit from organic agriculture, mainly due to soil improvements, through reduced exposure to toxic chemicals and lower input costs, which in turn reduces dependency on money lenders. Organic agriculture enables smallholder farmers in the study region to improve their livelihood by providing access to training and by organizing in groups. Important social impacts identified in this study were capacity building and strengthened communities, through training and institution building. However, a higher workload, due to the higher work intensity of organic farming practices, was also observed, with this impacting women more than men. Environmental conditions and gender aspects still remain challenging.

Dengue fever, a mosquito-borne viral disease, has become a major public health problem with marked expansion in recent decades. Dengue has now become hyperendemic in India with co-circulation of all the four serotypes. Herein, we report an unprecedented outbreak which occurred during August to October 2011 in Odisha, eastern India. This is the first report of a large epidemic in Odisha. Detailed serological and molecular investigation was carried out to identify the aetiology. Almost half of the samples were found to be dengue antigen (NS1) positive. Further molecular assays revealed circulation of mixed dengue serotypes (DENV-2 and DENV-3). Cosmopolitan genotype of DENV-2 and -3 were identified as the aetiology by phylogenetic analysis. Interestingly, a new lineage of DENV-3 within cosmopolitan genotype was incriminated in this outbreak. The emergence of the unprecedented magnitude of the dengue outbreak with the involvement of a novel lineage of DENV in a newer state of India is a major cause for concern. There is an urgent need to monitor phylodynamics of dengue viruses in other endemic areas.

Coastal and rural parts of Odisha are home to indigenous ducks, which are mostlyreared for meat and egg production. Cross performance of the indigenous duckwith exotic breeds, along with the suitability of crossbreeds for commercialrearing in the region are highlighted in this review paper. The crossbreedsperform comparatively better for most economic traits compared to the indigenousduck. The cross of the indigenous duck (male) with the Khaki Campbell (female)perform better in respect to different growth and production traits. Indigenousducks in combination with White Pekin perform better in respect to juvenilegrowth, carcass quality and egg production. Most of the economic traits haveshowed desirable heterosis in crossbreds. The performance of indigenous duckskept under free range conditions, molecular characteristics, mortality patternand disease incidence, nutritional, and haematological studies are included inthis review.

Elephants are threatened globally by habitat loss, poaching and accelerating levels of human–elephant conflict. In the state of Odisha, east India, electrocution by domestic electric power lines is causing mortality of the Asian elephant Elephas maximus. We collated data on elephant mortality from such electrocution in the villages surrounding elephant habitat for a period of 12 years (2001–2012). During this period 118 elephants were killed in 91 incidences. Most deaths (73.68%) were a result of accidental contact with electric power lines whilst elephants were moving into agricultural areas for crop raiding. The increasing human population, poor electrical infrastructure and ivory poaching pose serious threats to the continued survival of these elephants. To reduce elephant mortality from electrocution and to ensure the long-term survival of this population of elephants we recommend strengthening of the electrical infrastructure, minimizing habitat destruction, increasing public awareness of the problem, and stronger law enforcement.

A large outbreak of cholera reported during April–July 2009 in the Kendrapada district of Odisha, India was investigated. Forty-one rectal swabs and 41 water samples, collected from diarrhoeal patients and from different villages were bacteriologically analysed for the isolation of bacterial enteriopathogens, antibiogram profile and detection of various toxic genes. The bacteriological analysis of rectal swabs and environmental water samples revealed the presence of V. cholerae O1 Ogawa biotype El Tor. The V. cholerae strains were resistant to ciprofloxacin, co-trimoxazole, chloramphenicol, streptomycin, ampicillin, furazolidone and nalidixic acid. The multiplex polymerase chain reaction (PCR) assay on V. cholerae strains revealed the presence of ctxA and tcpA genes. The mismatch amplification of mutation assay (MAMA) PCR on clinical and environmental isolates of V. cholerae revealed that the strains were El Tor biotype, which harboured the ctxB gene of the classical strain. The random amplified polymorphic DNA PCR analysis and pulsed-field gel electrophoresis results indicated that the V. cholerae isolates belonged to the same clone. This investigation gives a warning that the El Tor variant of V. cholerae has spread to the coastal district causing a large outbreak that requires close monitoring and surveillance on diarrhoeal outbreaks in Odisha.
