Today, water supply in order to achieve sustainable development goals is one of the most important concerns and challenges in most countries. For this reason, accurate identification of areas with groundwater potential is one of the important tools in the protection, management and exploitation of water resources. Accordingly, the present study was conducted with the aim of modeling and predicting groundwater potential in Markazi province, Iran using Multivariate adaptive regression spline (MARS) and Support vector machine (SVM) machine learning models and using two random search (RS) and Bayesian optimization hyperparameter algorithms to optimize the parameters of the SVM model. For this purpose, 18 variables affecting the groundwater potential and 3482 spring locations were used to model the groundwater potential. Data for modeling were divided into two categories of training (70%) and validation (30%). The receiver operating characteristics (ROC) were used to evaluate the performance of the models. The results of evaluation models showed that using hyperparameters random search and Bayesian optimization were improved SVM accuracy in training and validation stages. Bayesian optimization methods are very efficient because they are consciously choosing the parameters of the model that this strategy improves the performance of the model. Evaluating accuracy in the validation stage showed that the AUC value is for MARS, SVM, RS-SVM and B-SVM models 87.40%, 88.25%, 90.73% and 91.73%, respectively. The results of assessment variables importance showed elevation, precipitation in the coldest month, soil and slope variables have the most importance in modeling groundwater potential, while aspect, profile curvature and TWI variables, have the least importance in predicting groundwater potential in Markazi province. � 2022 Elsevier B.V.
Geospatial analysis of the distribution of urban green spaces: a study of four Indian cities
(Routledge, 2021-07-27T00:00:00) Kaur, Navjotpreet; Kaur, Mandeep; Padhi, Saumya Sibani; Singh, Kiran Kumari
The urban green spaces are immensely significant to ensure quality of life in a city. However, their spatial distribution is found to be inequitable. The study investigates spatial distribution of green space through remote sensing data at different times in four Indian cities. It further examines the distribution of urban parks with respect to the location of slums. The results demonstrate that green spaces in the study areas changed considerably in the last two decades. The public urban parks are far from slum areas, and their spatial distribution is inequitable. Urban green spaces should be considered a matter of environment justice. � 2021 Informa UK Limited, trading as Taylor & Francis Group.
Green, open spaces and transport for healthy and sustainable cities in asian developing countries
(Universiti Putra Malaysia Press, 2021-07-31T00:00:00) Singh, Kiran Kumari; Katewongsa, Piyawat; Wijaya, Nurrohman; Kwan, Soo Chen
Introduction: This paper presents the case studies of the green, open spaces and transport issues in three cities of the Asian region based on the work of participants from the Workshop of Health in Urban Planning. Methods: Three case studies were collected from the participants of Thailand, India, and Indonesia, and compiled under the theme. Results: The first case study presents findings from the Thailand's Survey on Physical Activity (SPA), and various strategies taken by the Thai government to improve physical activity levels among the Thai population and children, including improved accessibility, walkability; and reconstruction of school curricula. The second case study is an empirical study of the geographical extent and type of green spaces accessible to the urban population, and their usage in the city of Varanasi, India, in the wake of Yoga practice popularity. The third case study discusses the insufficient transport infrastructures, along with the influx of visitors from outside the city as the cause of severe traffic congestions and emissions in Bandung city, Indonesia. The governments' action plans and recommendations for improvements of the city environment are discussed. Conclusion: Integrating health into urban and transport planning needs co-operations from multiple stakeholders including the government, private sectors, and the communities, especially from the early phase of development. � 2021 UPM Press.

MILITARY GEOGRAPHY AND TRANSFORMATIONAL TRAJECTORY OF THE PUNJAB (1849-1947): AN APPRAISAL
(Central University of Punjab, 2018) Singh, Maninderjit; Singh, Kiran Kumari
This study investigated how the making of modern Punjab, its political configurations, social relations, and economic lives were affected by military geography and shaped by ethos of militarism and militarization instituted by the British Indian Empire. Military geography of Punjab and its effects on the lives of the people and landscape was under researched in the history of Punjab’s human geography and even in urban studies and sociology of change. In such a context, the proposed study is a significant attempts to unravel the role of militarism, military activities and related developments in shaping the colonial times and spaces. Though it looks at the specific military history of Punjab in this connection, which in itself would be a significant contribution, at a larger level the work will emphasise on the colonial military history of British India and consequent transformations driven by military geography with a considered position that the whole Indian sub-continent did not follow a single and pre-determined historical trajectory in this regard. The original contribution of this work lies particularly in the arrangement and manifestation of cartographic presentations and historical accounts in context to military activities. It also gives a new background to the ways through which military geography can be defined. The definition has moved on just from ‘the effect of v geography on military activities and militarism’ to ‘the ways in which military activities are geographically constituted’ to the proclamation of ‘space and power’. This work is integrative and based on the appraisal of the background of conversion of Punjab into garrison state and the observation effect of military activities on the landscape. Those landscapes are selected, mapped, interpreted and contextualised for detailed study. It gives the expression of reality of the impact of military activities on social, economic and spatial sphere. While transformation of selected cantonment towns are examined in two chapters to decipher this phenomenon but the work retains military geography of Punjab in entire scene.

(Springer Science and Business Media Deutschland GmbH, 2022-04-11T00:00:00) Gupta, Palak; Singh, Kiran Kumari; Balodhi, Ashutosh; Jain, Khushi; Deeba, Farah; Salam, Nasir
Purpose: Intestinal protozoan parasites are responsible for diarrheal diseases causing significant morbidity and mortality. Entamoeba histolytica is the principle protozoan parasite associated with diarrheal infections. The infection is often associated with inaccessibility to clean drinking water and poor sanitary conditions in low- and middle-income countries including India. A comprehensive systematic review was performed to evaluate a reliable nationwide estimate for prevalence and geographic distribution of amoebiasis in India and the complications associated with it. Methods: We used the PRISMA guidelines to perform a systematic review and meta-analysis of articles published between the year 2001�2020. Two English language databases PubMed and Web of Science were searched to achieve relevant studies. Results: Initial searches resulted in 467 studies out of which 64 eligible articles involving data from 289,659 human subjects from 12 states and 4 union territories were included in the final analysis. Prevalence of amoebiasis ranged from 3-23% in asymptomatic population, 0.64�11% in symptomatic patients and 1�17.5% in HIV-infected patients. Highest prevalence was seen in Tamil Nadu, Andaman Nicobar Island and North East India. Extra intestinal invasion of Entamoeba histolytica leading to complications such as amoebic liver abscess, amoebic colitis, colonic perforation and ameboma were also reported. Such complications have the potential to increase healthcare burden and may prove to be fatal. Conclusion: Amoebiasis remains a significant public health issue in India responsible for diarrheal diseases causing significant morbidity and mortality. Entamoeba histolytica is the principle protozoan parasite associated with amoebiasis. Public health efforts should be directed towards its control and better diagnostic methods should be employed for distinguishing between pathogenic and non-pathogenic species of Entamoeba. � 2022, The Author(s) under exclusive licence to Witold Stefa?ski Institute of Parasitology, Polish Academy of Sciences.

SLUMS IN LUDHIANA AND BATHINDA CITIES OF PUNJAB: A SOCIO-GEOGRAPHICAL ANALYSIS
(Central University of Punjab, 2019) Kaur, Amandeep; Singh, Kiran Kumari
Wellbeing of slum dwellers needs efficient delivery of basic amenities and facilities. Over many decades several programmes and policies have been implemented to ensure decent quality of life to the slum dwellers but parts of many cities are still in the state of deprivation from basic amenities. This study analyses the status of available basic amenities and facilities in two cities of Punjab: Ludhiana and Bathinda. The study also highlighted the effectiveness of policies and programs in slums of both the cities. Field survey was conducted in different phases to collect data on eight basic amenities and facilities in slum areas. The study did not only brought out the status of availability of basic amenities but also analysed the level of satisfaction of the slum dwellers. The study also focused on the gender wise participation of slum dwellers in urban economic activities by examining the factors influencing their participation. The desirable data for the present study was collected from secondary and primary sources. The secondary data for the study was collected from publishes and unpublished resources such as Punjab Municipal Infrastructure Development Company, Municipal Corporations and Town and Country Planning departments of Ludhiana and Bathinda cities, research papers, articles, books, newspapers and other web sources. The primary data was collected through interview schedule and check list from selected notified and non-notified slums of Ludhiana and Bathinda cities. The collected data was analysed by using various statistical methods like descriptive statistics, multiple regression, simple probit and Student’s t test (two tailed). The study revealed that the overall condition of non-notified slums is more severe in iv terms of availability of basic facilities as compare to notified slums. Finding of the study for two cities suggest that slums of Bathinda city are in poor conditions of sewerage and solid waste management and slums of Ludhiana city lack government healthcare facilities, government schools, roads and public transport facilities. The finding calls for urgent attention to ensure the basic amenities in slums of both the cities. The study also advocates to shift the focus of plans and policies towards delivery of basic amenities and services keeping in view the quality of life of slum dwellers. The study brought up suitable recommendations for the upgradation of slums and efficient delivery of basic infrastructures and services in slums.
Spatiotemporal dynamics of urban green and blue spaces using geospatial techniques in Chandannagar city, India
(Springer Science and Business Media Deutschland GmbH, 2021-10-12T00:00:00) Ghosh, Pritha; Singh, Kiran Kumari
Green and blue spaces are important landscape elements in a city and there is strong literary evidence available regarding the ecological, social, cultural and recreational benefits of these spaces to people and urban sustainability. Comprehensive quantitative assessment of these spaces is gaining scientific recognition for their utility in sustainable urban planning and drafting greening policies. This study analyzed the spatiotemporal change in urban green and blue spaces in Chandannagar city, India through quantitative assessment for the years 1991, 2001, 2011, and 2020 using Landsat data of 30�m spatial resolution. Normalized Difference Vegetation Index and Normalised Difference Water Index was applied to extract information on urban green and blue spaces. The classified maps were validated through field observations and Google earth images. Spatio-temporal analysis was carried out at ward level to analyze the distribution of urban green spaces (UGS) at the micro level. The result indicated that there was a reduction in green and blue spaces in the central and eastern parts of the city while there was a good amount of UGS in the western part of the city. The findings of this study shed light on important policy implications for the UGS planning in the city. � 2021, The Author(s), under exclusive licence to Springer Nature B.V.

(Central University of Punjab, 2019) Kumar, Gaurav; Singh, Kiran Kumari
Wetland ecosystem is regarded as one of most productive system of the earth surface due to its inclusive nature to supports a variety of flora and fauna. There are a number of functions and services provided by the wetland ecosystem which includes purification of water, protection from floods, groundwater replenishment, woods for fuel and commercial uses, fish resources, recreational and social services. Therefore, the study is an attempt to evaluate the socio-economic significance of wetland area and their relation with the livelihood activities of local people in Harike, Ropar and Nangal wetlands of Punjab. The economic value of the wetland products and services have been calculated from direct use value which employed different methods. The study also focused on the threat perceptions related to impact of human developmental activities inside the wetland boundaries. The people participation for the conservation and management of the wetland area has also been studied through their willingness to pay for such actions. The data desirable for the present study are collected from both secondary and primary sources. The secondary data for the study has been collected from published and unpublished resources such as from Department of Forest and Wildlife Preservation (Punjab), Department of Forest and Wildlife preservation (Firozpur), Department of Forest and Wildlife Preservation (Ropar), Harike Sanctuary Office, Punjab State for Science and Technology (PSCST), ENVIS, articles, research papers, newspapers, books and other internet resources. The Primary data has been collected through interview schedule of the iv people of selected villages/towns falling within one kilometre buffer zone around the Harike, Ropar and Nangal wetlands. The collected data are analysed by using statistical methods like descriptive statistics, regression and probit model. The study came up with suitable recommendations for conservation of wetland.
