The productivity of dairy animals is heavily reliant on the timely access to sufficient, high-quality fodder. This study analyzes the ex-post impact of Model Fodder Villages on the livelihood security of dairy farmers in Bundelkhand region of central India. The study used cross-sectional data from 437 farmers and employed the inverse-propensity-weighting regression adjustment (IPWRA) method for impact evaluation and verified the robustness of the results through matching methods. The findings show that dairy farmers in model fodder villages are 14–19% more likely to improve habitat security, 19–21% more likely to enhance economic security, and 13–16% more likely to increase food security. Our findings also indicate that factors such as age, education, household size, dependency ratio, off-farm income, adult cattle units, and access to roads, markets, credit, and training play significant roles in adopting improved fodder practices. The study's methodology provides a reliable approach to evaluating the impact of interventions that improve access to fodder and related resources, aiming to enhance the livelihoods of dairy farmers and agricultural communities.

This study assessed the impact of improved green fodder production activities on technical efficiency (TE) of dairy farmers in climate vulnerable landscapes of central India. We estimated stochastic production frontiers, considering potential self-selection bias stemming from both observable and unobservable factors in adoption of fodder interventions at farm level. The empirical results show that TE for treated group ranges from 0.55 to 0.59 and that for control ranges from 0.41 to 0.48, depending on how biases are controlled. Additionally, the efficiency levels of both adopters and non-adopters would be underestimated if the selectivity bias is not appropriately accounted. As the average TE is consistently higher for adopter farmers than the control group, promoting improved fodder cultivation would increase input use efficiency, especially in resource-deprived small holder dairy farmers in the semi-arid tropics.

Using different archives, I show how indigeneity was constructed by the Santal themselves during the second half of the nineteenth century, through various figures such as rebels and prophets. This has produced a Santal indigenous knowledge at the interface of orality and writing, revolving around two dimensions—an emergent historical consciousness and a feeling of shared identity, which still informs Adivasi resistance today, enabling them to voice assertion over natural resources. The sacralization of the landscape through pilgrimages and ritual commemorations entails the liberation of formerly encompassed identities, allowing the subaltern communities a certain visibility in the public sphere. Providing a new imagining against dispossession and memory loss, indigenous knowledge, which combines multi-scripturality and ritual innovations, becomes a resource for politics of representation as well as of a common Santal identity.

Dengue is regarded as the most important arboviral disease. Although sporadic cases have been reported, serotypes responsible for outbreaks have not been identified from central India over the last 20 years. We investigated two outbreaks of febrile illness, in August and November 2012, from Korea district (Chhattisgarh) and Narsinghpur district (Madhya Pradesh), respectively. Fever and entomological surveys were conducted in the affected regions. Molecular and serological tests were conducted on collected serum samples. Dengue-specific amplicons were sequenced and phylogenetic analyses were performed. In Korea and Narsinghpur districts 37·3% and 59% of cases were positive, respectively, for dengue infection, with adults being the worst affected. RT–PCR confirmed dengue virus serotype 1 genotype III as the aetiology. Ninety-six percent of infections were primary. This is the first time that dengue virus 1 outbreaks have been documented from central India. Introduction of the virus into the population and a conducive mosquitogenic environment favouring increased vector density caused the outbreak. Timely diagnosis and strengthening vector control measures are essential to avoid future outbreaks.

In the sheared and foliated granitoids of the Proterozoic Gavilgarh–Tan Shear Zone (GTSZ) in central India, two types of pseudotachylite (Pt-M and Pt-C) are recognized. Pt-M layers are interbanded with mylonite and ultramylonite, show strong internal plastic deformation and buckle folding concurrent with the host rocks, and appear to have formed within the greenschist facies (300–400 °C) in the brittle–plastic transitional (semi-brittle) regime. Pt-C layers show sharp contacts with the host rock, exhibit abundant coeval cataclasis, preserve no evidence of subsequent plastic deformation, and formed at shallower depths, at temperature < 300 °C. Sulphide droplets and embayment of quartz grain margins in the pseudotachylite (Pt-C) matrix indicates a melt origin. Ductile shear sense criteria in the host mylonites are consistently sinistral, while those associated with the deformed pseudotachylite (Pt-M) layers are dextral. It appears therefore that the host mylonite/ultramylonite foliation experienced reactivated slip movement in the ‘semi-brittle’ zone when pseudotachylite was generated and subsequently ductilely deformed. The brittle pseudotachylite (Pt-C) layers were generated later at a shallower level, and at a lower temperature. They are spatially associated with a set of foliation-parallel brittle shears with sinistral-sense displacements. The multiple episodes of frictional melt generation within the Gavilgarh–Tan Shear Zone illustrate that it has a complex history of multiple reactivations. It therefore represents an important new area for the study of seismic behaviour of the upper crust along pre-existing structures and may facilitate a better geological understanding of the present seismic activity in the central Indian Shield.
