Demographic Trends

The 2011 census data reveals a notable increase in the urban population of Nagaur Citycompared to previous decades. This growth is indicative of urbanization trends and suggests a corresponding expansion of urban areas. Rural-to-urban migration was the main reason for the expansion of the urban area of the city. The reasons for migration include economic opportunities, seeking employment, education, quality higher education, etc. The impact of this trend can be seen in the demographic structure of the city.

The population of the city increased from 68,194 to 1,05,218 in the period of two decades namely from 1991 to 2011. More than 35,000 people were added to the total population of the city. The annual growth rate in Nagaur City between 1991 and 2001, at 3.7 percent, significantly surpassed the district's growth rate of 2.6 percent. (Figure-2)

While the number of males has consistently exceeded the number of females in Nagaur City, there is an intriguing trend observed in the percentage share of females within the total urban population. Notably, this percentage has shown a continuous increase overtime, rising from 46.24 percent in 1991 and 47.45 percent in 2001 to 48.56 percent in 2011. This data suggests a positive trend towards gender equality in the urban population structure. (Figure-3&4)

Population density, defined as the number of individuals residing perunit area, is a criticalmetric for assessing urbanization dynamics. Nagaur City, with an area of 37.8 square kilometers, has witnessed a consistent rise in population density overtime, leading to significant implications for land-use patterns and resource consumption. In 1991, the population density of Nagaur City stood at 1,804 individuals per square kilometer, which surged to 2,340 in 2001. This upward trajectory persisted, culminating in a population density of 2,782 by the year 2011. (Figure-5)

The census defines slums as areas unfit for human habitation, characterized by overcrowding, poor building arrangement and design, narrow roads, lack of ventilation, sanitation facilities, and safety and health measures. Over the last few decades, there has been a steady increase in the number of slums. In 1991, the percentage of slums was 3.19%, which rose to 8.40% in 2001, and alarmingly continued to increase. By 2011, it reached 11.51% of the total population of the city. The living conditions in these slums have deteriorated due to the unhealthy impacts of urbanization, with few facilities available, posing a significant concern for urban management. The growth of slums raises serious questions about urban management, as without proper management, slums can become an urban disaster. (Figure-6)

Socio-Economic Impacts

The social impact of urban sprawl on Nagaur City is profound, shaping the fabric of community life and interpersonal dynamics. As urban areas expand, there is a transformation in social interactions and community structures, with implications for social integration and cohesion. The influx of migrants and demographic shifts associated with urban sprawl may lead to the formation of diverse and heterogeneous communities, fostering cultural exchange and enrichment. However, the spatial fragmentation of urban areas and the proliferation of informal settlements may also contribute to social exclusion and marginalization, exacerbating socio-economic disparities and hindering social cohesion. Access to essential services and amenities may vary across different are as of the city, impacting the quality of life and well-being of residents. Additionally, rapid urban expansion may strain social infrastructure such as schools, healthcare facilities, and community centers, posing challenges to equitable access and service delivery.

The economic impact of urban sprawl on Nagaur City is multifaceted, with implications for employment patterns, economic sectors, and work force participation. In 2001, a significant portion of the labor force was engaged in traditional economic activities, with 3.4 percent as cultivators, 1 percent as agricultural workers, and 11 percent as household industry workers. However, the majority, comprising 84.2 percent, were involved in other sectors, prominently the service sector, which emerged as the primary employment generator. The service sector's dominance in employment signifies a shift towards a more diversified and modern economy. In contrast, in 2011, while the percentage of cultivators and agricultural workers increased slightly to 5.7 percent and 4.1 percent, respectively, the proportion of household industry workers declined to 9.2 percent. This shift reflects changes in economic structure and employment opportunities over the decade. Notably, Nagaur City's economy is characterized by the manufacturing and export of hand tools, edible oil, and gypsum powder, with traditional craftsmanship playing a significant role. However, it is concerning that women's participation in the labor force remains low, with only 17 percent of women being part of the workforce as per the 2011 population data. Addressing gender disparities in workforce participation and promoting inclusive economic growth is imperative for leveraging the economic potential of Nagaur City amidst urban sprawl. (Figure 7&8)

Impact on environment and ecology

The urban sprawl of Nagaur City has brought about significant environmental and ecological consequences, reshaping the landscape and altering natural eco systems. One prominent impact is the loss of green spaces, as agricultural land and natural habitats are converted into built-up are as, resulting in diminished biodiversity and disrupted ecological balance. Additionally, urban sprawl has led to the fragmentation of natural habitats, isolating wildlife populations and disrupting migratory routes, thus reducing habitat quality and increasing the risk of species extinction.

The expansion of urban areas has also contributed to decreased air quality, with increased vehicular traffic and industrial activities leading to air pollution, posing risks to both human health and ecosystem integrity. Furthermore, the conversion of agricultural and in to urban areas threatens food security and compromises the sustainability of local agricultural systems. Urban sprawlexacerbates water pollution and depletion issues, as increased surface run off and pollution from untreated sewage and industrial effluents contaminate water bodies, while excessive groundwater extraction for urban consumption exacerbates water scarcity. The proliferation of concrete surfaces and removal of vegetation exacerbate the urban heat island effect, causing higher temperatures in urban areas compared to surrounding rural areas, leading to heat-related illnesses and increased energy consumption for cooling.

Moreover, urban sprawl leads to the depletion and degradation of natural resources, including forests, wetlands, and soil, diminishing eco systems' cap a city to provide essential services such as water filtration and habitat provision. Impermeable surfaces associated with urban sprawl also increase flood risk, as natural drainage is reduced, posing threats to infrastructure, public safety, and ecosystem health.

Addressing these environmental and ecological impacts requires integrated land-use planning, sustainable development practices, and conservation efforts, including the implementation of green infrastructure, promotion of sustainable transportation options, and preservation of natural habitats.
