Soon after independence, India's northeastern region was swamped in a series of conflicts starting with the Naga secessionist movement in the 1950s, followed by others in the 1960s. The conflicts intensified and engulfed the entire region in the 1970s and 1980s. However, in the 1990s, following reclamation of ethnic identities amid gnawing scarcities, the conflicts slowly turned into internal feuds. Consequently, alliance and re-alliance among the ethnic groups transpired. In the 2000s, it finally led to the balkanization of ethnicity-based autonomy movements in the region. Unfortunately, the state's ad-hoc measures failed to contain protected conflicts and, instead, compounded the situation and swelled hybrid ethnic identities.

With the growth of technology, modernization, and changes in food habits, agricultural cropping pattern of the country has undergone a major shift in the recent past, moving away from the cereal to non-cereal crops cultivation, especially toward the horticulture crops. Horticulture has been one of the fastest growing sectors within the larger agriculture activities in India, and the State of Karnataka is at the forefront in this context. With the help of secondary data and by employing Simpson's Diversification Index, crop diversification toward horticulture across the districts of Karnataka was explored. Using regression growth trends, the districts have been categorized as high, medium, low, and negative growth trend of horticulture crop area, and the districts have been further regrouped according to their agro-climatic zones. The study found that the districts of Gulbarga, Raichur, Bijapur, Bidar, Koppal, Bagalkot, and Bellary showed a complete diversification toward horticulture crops, whereas the districts of Kolar, Udupi, and Dakshina Kannada were found to be diversified the least. The study also explored that the districts having complete diversification toward horticulture sector were found to have devoted a lesser share of their cultivable area under horticulture crops. Also, most of the highly diversified districts have come under the dry agro-climatic zones and experienced a high growth rate of horticulture crops cultivation from triennium ending (TE) 2002-2003 to TE 2009-2010. However, the lesser diversified districts have got lesser growth rate of area under the horticulture crops, but devoted relatively a higher share of area under the crops.

Electrical resistivity tomography (ERT) is examined as a method to provide spatially continuous information about aquifer properties through imaging of tracer flow and transport in an unconfined aquifer. Field data were collected at the Massachusetts Military Reservation, Cape Cod, Massachusetts, during the summer of 2002. Highresolution images in both space and time of the movement of an electrically conductive sodium-chloride tracer in three dimensions (3-D) help delineate aquifer heterogeneity. Sixty 3-D data sets were collected between four corner-point wells for 20 days following the 9-hour injection. Concentrations were measured at a 15-point multilevel sampler centrally located within the ERT array, at the production well, and at two wells external to the central array. The tomograms indicate movement of the saline tracer consistent with measured concentration data. The resistivity tomograms serve as an appropriate surrogate for concentration maps that are otherwise impossible to obtain. Under reasonable assumptions, estimates of groundwater velocity and hydraulic conductivity can be obtained by tracking the tracer.
