Critically examine the role of groundwater depletion in exacerbating the water crisis in Delhi and Bangalore. What measures can be implemented to manage groundwater resources more sustainably?
India being the largest consumer of groundwater accounting a major chunk i.e around 25% of the total world's groundwater withdrawal which indicates a great dependency on it, and so its depletion will lead to various problems, as megacities like Bangalore and delhi are facing major shortage of waterRead more
- Due to the deforestation in the megacities,the groundwater is not getting recharged as its depleting
- Wetlands encroachments
- No strict conservation policies of water recharging
- Climate change is also exacerbating this crisis as high temperature are responsible for more evaporation
- Way forward
- A stringent policy should be there for the overall recharging of the aquifers through promising methods like rainwater harvesting and various traditional methods
- Community awareness campaign can play a major role in generating awareness
- Wetlands conservation programme should be there
- Sustainable use of groundwater resources should be encouraged
- Being the largest consumer and catering the largest population of the world we should think of this challenging problem and implement the strategic management of not only the groundwater but all sources of water.
See lessdoes over usage of mobile phone at a young age have bad affect on children
Excessive mobile phone use at a young age can have detrimental effects on children’s development. Research by the American Academy of Pediatrics (AAP) highlights several concerns. Prolonged screen time can lead to issues such as reduced attention span and impaired cognitive development. For instanceRead more
Excessive mobile phone use at a young age can have detrimental effects on children’s development. Research by the American Academy of Pediatrics (AAP) highlights several concerns. Prolonged screen time can lead to issues such as reduced attention span and impaired cognitive development. For instance, a study published in JAMA Pediatrics (2019) found that increased screen time in young children is associated with lower scores in language and cognitive development tests.
Furthermore, excessive mobile phone use is linked to disrupted sleep patterns. Research published in Sleep Medicine Reviews (2020) indicates that exposure to screens before bedtime can interfere with melatonin production, leading to poor sleep quality and increased risk of sleep disorders. Poor sleep can exacerbate behavioral problems and negatively impact academic performance.
There is evidence suggesting that heavy mobile phone use can contribute to social and emotional issues. A study in Cyberpsychology, Behavior, and Social Networking (2018) found that excessive screen time is associated with increased risks of anxiety and depression among adolescents, due to reduced face-to-face interactions and increased exposure to cyberbullying.
Additionally, excessive mobile phone use can impair cognitive development, disrupt sleep, and contribute to mental health issues in children, underscoring the need for balanced screen time management.

A Tsunami Warning Centre operating on 24×7 basis.
A network of land-based seismic stations for earthquake detection.
A network of 12 Bottom Pressure Recorders (that could detect and measure a change in water level of 1 cm at water depths of up to 6 km of water).
A network of tsunami buoy system it measures the change in height of the water column then this water column height is communicated and then relayed via satellite to the tsunami warning center.
Real-time observational network for upper ocean parameters and surface met-ocean parameters.
A network of 50 real time tide gauges, radar- based coastal monitoring stations and current meter moorings to monitor progress of tsunami and storm surges .

BPRs installed in the Deep Ocean and Buoys are the key sensors to confirm the triggering of Tsunami through INSAT end-to-end communication takes place and disseminate alerts to MHA by satellite- based virtual private network (VPN DMS). This network enables early warning center to disseminate warnings to the MHA, as well as to the State Emergency Operations Centers.
Do you think that the water shortage in Indian cities is an infrastructural issue, climate change or simply overuse and misuse of water by people ? Justify your answer by taking Delhi's example into consideration..
The water shortage in Indian cities, including Delhi, is a complex issue resulting from a combination of infrastructural deficiencies, climate change, and overuse and misuse of water resources by people. Here's an analysis considering Delhi's example: Infrastructural Issues Aging Infrastructure: DelRead more
The water shortage in Indian cities, including Delhi, is a complex issue resulting from a combination of infrastructural deficiencies, climate change, and overuse and misuse of water resources by people. Here’s an analysis considering Delhi’s example:
Infrastructural Issues
Climate Change
Overuse and Misuse of Water
- High Per Capita Water Consumption: Delhi’s population consumes water at a rate higher than the national average, driven by lifestyle changes and increasing urbanization.
- Lack of Water Conservation Practices: Despite the scarcity, water conservation practices are not widely adopted. Practices like rainwater harvesting, greywater recycling, and efficient irrigation methods are not adequately implemented.
- Pollution and Waste: Industrial discharge, domestic waste, and agricultural runoff contribute to the pollution of water bodies, reducing the usable water supply.

Recent advances in oceanographic equipment have significantly increased our understanding of deep-sea trench biology. Autonomous Underwater Vehicles (AUVs), such as the “ABYSS,” are essential for this research. These robotic submarines can dive to great depths, navigate intricate underwater terrain, and collect data autonomously over lengthy periods of time. They create accurate maps of the seafloor and gather samples from previously inaccessible areas, offering fresh information about these fascinating habitats. Remotely operated vehicles (ROVs) are also required for deep-sea exploration. These tethered robots, which are operated from the surface, are outfitted with high-definition cameras, manipulator arms, and a variety of sensors. ROVs, like the “Deep Discoverer,” have explored the Mariana Trench, recording amazing photographs and films while also gathering biological and geological samples.
This hands-on experience with the deep-sea environment allows scientists to investigate life forms and ecosystems directly, resulting in the discovery of new species and a greater knowledge of how life adapts to such harsh conditions.
Furthermore, new sensor technologies, such as chemical and biological sensors, have increased our capacity to monitor environmental conditions and identify indications of life. These technology advances are providing new insights into the biodiversity and biological dynamics of deep-sea trenches.
