The decreasing effectiveness of antimicrobial agents is a global public health threat, yet risk factors for community-acquired antimicrobial resistance (CA-AMR) in low-income settings have not been clearly elucidated. Our aim was to identify risk factors for CA-AMR with extended-spectrum β-lactamase (ESBL)–producing organisms among urban-dwelling women in India. We collected microbiological and survey data in an observational study of primigravidae women in a public hospital in Hyderabad, India. We analyzed the data using multivariate logistic and linear regression and found that 7% of 1,836 women had bacteriuria; 48% of isolates were ESBL-producing organisms. Women in the bottom 50th percentile of income distribution were more likely to have bacteriuria (adjusted odds ratio 1.44, 95% CI 0.99–2.10) and significantly more likely to have bacteriuria with ESBL-producing organisms (adjusted odds ratio 2.04, 95% CI 1.17–3.54). Nonparametric analyses demonstrated a negative relationship between the prevalence of ESBL and income.
Abstract: In November 1998, ‘mujahideen’ warriors climbed the heights above Kargil in Indian held Kashmir, crossed the Line of Control, and occupied Indian military posts. These ‘mujahideens’ were really Pakistani soldiers clad in civilian garb on a secret mission. This was the beginning of the war in Kargil between two nuclear neighbors (India and Pakistan). This study critically evaluates the relationship between ‘learning’ and risk-prone behavior of Pakistan in the midst of technological maturation. Should we be confident and rely on nuclear deterrence and believe that Kargil-like crisis will never happen again? This talk will explain the story of Kargil from a theoretical lens of nuclear learning, demonstrating how difficult it has been for Pakistan to learn appropriate lessons given the firewalls of convictions, cover-ups, and confirmation biases.

Abstract: This research investigates why and how regional nuclear powers come to develop specific kind of nuclear delivery systems, especially a submarine-based ballistic missile (SSBN) force. In the second nuclear age, as new nuclear states develop sophisticated delivery systems including SSBNs, understanding the logic and process of their nuclear force development is essential for both regional and international security. The origins and development process of India’s nuclear submarine program suggests that nuclear force development is a historically contingent process. This data-driven research, based on newly declassified archival documents from the Indian archives and extensive oral history interviews, refutes teleological narratives that either argue for technological determinism or the need for projecting nuclear deterrence as the primary causal variables. By situating India’s nuclear submarine program in the organizational routines of its nuclear scientific bureaucracy, bureaucratic politics of its military-scientific complex and the military socialization of the Indian Navy, this research explains India’s most secretive military-scientific programs. This comprehensive empirical research, currently based on a single case study, also addresses an important theoretical question in the field of international security studies: why states develop specific kinds of weapon systems, including those for nuclear weapons delivery?
Speaker bio: Prior to joining CISAC as a Nuclear Security Postdoctoral Fellow, Yogesh Joshi was an Associate Fellow in the Strategic Studies Program at the Observer Research Foundation, New Delhi. He recently received his PhD from Jawaharlal Nehru University specializing in Indian foreign and security policy.
At CISAC, Yogesh is finishing a book manuscript on the history of India's nuclear submarine program. His research traces the origins, process and development of India's nuclear submarine program using multi-archival sources and extensive oral history interviews. Yogesh’s data-driven research posits that India’s nuclear submarine program was riddled with shifting motivations, ambivalent rationales and halting progress. Rather than being driven by a single coherent strategic plan, India stumbled upon a submarine-based nuclear deterrent. By situating the nuclear submarine program in India’s Cold War security policy, its nuclear policy, its naval strategy in the Indian Ocean, the bureaucratic politics of its military-scientific complex and its quest for technological prestige, this research is an attempt to understand path-dependency in one of India’s most secretive military-scientific programs. It not only has implications for explaining India's nuclear program and policy but also provides an avenue to explain the process of decision-making behind state's pursuance of specific kinds of nuclear delivery systems. This research is supported by the MacArthur foundation.

Food security will be increasingly challenged by climate change, natural resource degradation, and population growth. Wheat yields, in particular, have already stagnated in many regions and will be further affected by warming temperatures. Despite these challenges, wheat yields can be increased by improving management practices in regions with existing yield gaps. To identify the magnitude and causes of current yield gaps in India, one of the largest wheat producers globally, we produced 30 meter resolution yield maps from 2001 to 2015 across the Indo-Gangetic Plains (IGP), the nation's main wheat belt. Yield maps were derived using a new method that translates satellite vegetation indices to yield estimates using crop model simulations, bypassing the need for ground calibration data. This is one of the first attempts to apply this method to a smallholder agriculture system, where ground calibration data are rarely available. We find that yields can be increased by 11% on average and up to 32% in the eastern IGP by improving management to current best practices within a given district. Additionally, if current best practices from the highest-yielding state of Punjab are implemented in the eastern IGP, yields could increase by almost 110%. Considering the factors that most influence yields, later sow dates and warmer temperatures are most associated with low yields across the IGP. This suggests that strategies to reduce the negative effects of heat stress, like earlier sowing and planting heat-tolerant wheat varieties, are critical to increasing wheat yields in this globally-important agricultural region.
The Ghadar movement cultivated strong ties of solidarity with Egyptian, Irish, and other anti-colonial movements. Competing visions of the future world order coexisted with common dissatisfaction with the contemporary world order. Ghadar linked militant diaspora intellectuals with activists in the subcontinent.
In the next decade and a half, China and India will become two of the world’s indispensable powers—whether they rise peacefully or not. During that time, Asia will surpass the combined strength of North America and Europe in economic might, population size, and military spending.

One of the greatest challenges in monitoring food security is to provide reliable crop yield information that is temporally consistent and spatially scalable. An ideal yield dataset would not only extend globally and across multiple years, but would also have enough spatial granularity to characterize productivity at the field and subfield level. Rapid increases in satellite data acquisition and platforms such as Google Earth Engine that can efficiently access and process vast archives of new and historical data offer an opportunity to map yields globally, but require efficient and robust algorithms to combine various data streams into yield estimates. We recently introduced a Scalable satellite-based Crop Yield Mapper (SCYM) that combines crop models simulations with imagery and weather data to generate 30 m resolution yield estimates without the need for ground calibration. In this study, we tested new large-scale implementations of SCYM, focusing on three regions with varying crops, field sizes and landscape heterogeneity: maize in the U.S. corn belt (390,000 km2), maize in Southern Zambia (86,000 km2), and wheat in northern India (450,000 km2). As a benchmark, we also tested a simpler empirical approach (PEAKVI) that relates yield to the peak value of a time series of spatially aggregated vegetation indices, similar to methods used in current operational monitoring. Both SCYM and PEAKVI were applied to data from all Landsat's sensors and MODIS for more than a decade in each region, and evaluated against ground-based estimates at the finest available administrative level (e.g., counties in the U.S.). We found consistently high correlations (R2 ≥ 0.5) between the spatial pattern of ground- and satellite-based estimates in both U.S. maize and India wheat, with small differences between methods and source of satellite data. In the U.S., SCYM outperformed PEAKVI in tracking temporal yield variations, likely owing to its explicit consideration of weather. In India, both methods failed to track temporal yield changes, with various possible explanations discussed. In Zambia, the PEAKVI approach applied to MODIS tracked yield variations much better (R2 > 0.5) than any other yield estimate, likely because the frequent cloud cover in this region confounds the other approaches. Overall, this study demonstrates successful approaches to yield estimation in each region, and illustrates the importance of distinguishing between accuracy for spatial and temporal variation. The 30 m resolution of Landsat-based SCYM does not appear to offer large benefits for tracking aggregate yields, but enables finer scale analyses than possible with the other approaches.
Since the 1960s, India’s groundwater irrigation has increased dramatically, playing an important role in its economy and people’s lives — supporting livelihoods of over 26 crore farmers and agricultural labourers who grow over a third of India’s foodgrains. These benefits, however, have come at the cost of increased pressure on groundwater reserves.
India is the world’s largest user of groundwater and, since the 1980s, its groundwater levels have been dropping. The severity of the problem is particularly acute in the northwest, where levels have plunged from 8m below ground to 16m, so that water needs to be pumped from even greater depths. Worse yet, much of this is non-renewable since recharge rates are less than extraction rates and replenishing this resource can take thousands of years.
This won’t last
Using up such “fossil” groundwater is unsustainable. Moreover, the future of monsoon rainfall remains uncertain; while some climate models predict an increase, others forecast a weakening monsoon, although changes in monsoon variability are already underway and will continue into the future. Historical records show the number of dry spells and the intensity of wet spells have risen over the past 50 years. As climate change alters the monsoon, the large stresses on India’s groundwater resources may increase.
