Question: 6 Describe major benefits of Geothermal Energy.
Answer:
Geothermal energy is natural heat from the interior of the earth that can be used to generate electricity as well as to heat up buildings.
HOW IS IT CAPTURED:
Geothermal systems can be found in regions with a normal or slightly above normal geothermal gradient and especially in regions around plate margins where the geothermal gradients may be significantly higher than the average value.
The most common current way of capturing the energy from geothermal sources is to tap into naturally occurring “hydrothermal convection” systems where cooler water seeps into the earth’s crust, is heated up, and then rises to the surface. When heated water is forced to the surface, it is relatively easy to capture that steam and use it to drive electric generators.

Question: 7 Discuss the applications of remote sensing and GIS in mitigating flood risk.
Answer:
Remote sensing is the process of detecting and monitoring the physical characteristics of an area by measuring its reflected and emitted radiation. Special cameras collect remotely sensed images, which help researchers “sense” things about the Earth.
Application of Remote Sensing In Flood Management
1. Flood Mapping and Monitoring
Accurate flood mapping and real-time monitoring are crucial for effective flood management. Remote sensing platforms such as satellites, aerial imagery, and unmanned aerial vehicles (UAVs) enable the collection of high-resolution data over large areas. These maps serve as a valuable resource for emergency response planning, evacuation strategies, and resource allocation.
2. Early Warning Systems
With the help of remote sensing, advanced early warning systems can be developed to alert communities about impending floods. By analyzing precipitation patterns, river levels, and soil moisture content, remote sensing technologies can provide valuable data for flood forecasting models.
3. Flood Damage Assessment
After a flood event, assessing the extent of damage is crucial for effective response and recovery efforts. Remote sensing techniques enable rapid and comprehensive damage assessment. High-resolution satellite imagery and aerial surveys provide detailed information about infrastructure damage, changes in land cover, and the impact on ecosystems.
4. Rainfall Estimation and Prediction
Accurate estimation and prediction of rainfall are essential for flood forecasting. Remote sensing technologies provide valuable insights into precipitation patterns by analyzing cloud cover, atmospheric conditions, and temperature gradients. This data helps meteorologists and hydrologists improve rainfall prediction models, enhancing the accuracy of flood forecasts and enabling better preparation and response to potential flood events.
5. River and Stream Monitoring
Monitoring the flow and behaviour of rivers and streams is essential in flood management. Remote sensing platforms offer valuable tools for monitoring water levels, flow rates, and sediment transport. Satellite altimetry and radar sensors provide continuous monitoring of river height changes, enabling the detection of floods and the assessment of river dynamics. This information aids in flood forecasting, infrastructure planning, and the identification of flood-prone areas.
Conclusion
The application of remote sensing in flood management has revolutionized our ability to prevent, prepare for, and respond to floods. By harnessing the power of remote sensing, policymakers, scientists, and communities can work together to minimize the impacts of floods, protect lives and property, and build resilient societies in the face of increasing flood risks.

Question: 14. Describe the concept of Biosphere Reserve in context of biodiversity conservation.
Answer:
Biosphere Reserve (BR) is an international designation by UNESCO for representative parts of natural and cultural landscapes extending over large area of terrestrial or coastal/marine ecosystems or a combination thereof. BRs are designated to deal with one of the most important questions of reconciling the conservation of biodiversity, the quest for economic and social development and maintenance of associated cultural values. BRs are thus special environments for both people and the nature and are living examples of how human beings and nature can co-exist while respecting each others’ needs.
BIOSPHERE RESERVES ARE DEMARCATED INTO FOLLOWING 3 INTER-RELATED ZONES:
CORE ZONE : Core zone must contain suitable habitat for numerous plant and animal species, including higher order predators and may contain centres of endemism. Core areas often conserve the wild relatives of economic species and also represent important genetic reservoirs having exceptional scientific interest.
BUFFER ZONE : The buffer zone, adjoins or surrounds core zone, uses and activities are managed in this area in the ways that help in protection of core zone in its natural condition. These uses and activities include restoration, demonstration sites for enhancing value addition to the resources, limited recreation, tourism, fishing, grazing, etc; which are permitted to reduce its effect on core zone.
TRANSITION ZONE : The transition area is the outermost part of a biosphere reserve. This is usually not delimited one and is a zone of cooperation where conservation knowledge and management skills are applied and uses are managed in harmony with the purpose of the biosphere reserve. This includes settlements, crop lands, managed forests and area for intensive recreation and other economic uses characteristics of the region.

Introduction | Define what global warming is with the help of the recent reports. |
Main Body | Enlist the Factors responsible Enumerate the consequences The global and Nation solution |
Conclusion | Relate it sustainable development that why we need to curb global warming. |
Climate change refers to significant, long-term changes in the global climate. The temperature of earth and its atmosphere as a whole is determined by the balance between incoming and outgoing energy. Climate change arises largely from changes to the earth’s heat balance. Many factors can influence this—both natural processes and Anthropogenic processes. It is the impacts from anthropogenic processes, through the enhanced greenhouse effect, which are likely to be causing contemporary climate change, which in turn could bring about considerable environmental, social and economic disruption if adequate mitigation and adaptation measures are not implemented. Global warming is the slow increase in the average temperature of the earth’s atmosphere because an increased amount of the energy (heat) striking the earth from the sun is being trapped in the atmosphere and not radiated out into space.
The IPCC (Intergovernmental Panel on Climate Change) report provides new estimates of the chances of crossing the global warming level of 1.5°C in the next decades, and finds that unless there are immediate, rapid and large-scale reductions in greenhouse gas emissions, limiting warming to close to 1.5°C or even 2°C will be beyond reach.
FACTORS CAUSING CLIMATE CHANGE
The Earth’s climate can be affected by a number of natural factors. The prominent ones are continental drift, volcanoes, ocean currents, the earth’s tilt, and comets and meteorites. The natural factors affect the climate change in a long term and persist for thousand to millions of years.
ANTHROPOGENIC (HUMAN CAUSED) FACTORS
Anthropogenic or manmade factors result in short term climatic changes. It involves the changes in the energy balance of the Earth – atmosphere system leading to changes in weather and climate. Scientists have been observing a change in the climate since the beginning of the 20th Century that cannot be attributed to any of the ‘natural’ influences of the past. Global warming has occurred faster than any other climate change recorded by humans and so is of great interest and importance to the human population.
Cause of anthropogenic (human caused) climate change includes greenhouse gases, aerosols and pattern of land use changes.
The Earth is endowed with a natural greenhouse effect where certain gases (known as greenhouse gases) in the atmosphere permit the sunlight to enter but absorb the heat radiation. They keep the average surface temperature on Earth around 14°C. Without the natural greenhouse effect, the Earth’s average surface temperature would be around -19°C. As the human activity has increased due to onset of industrial revolution, the emission of huge amount of Green House Gases is also increased which led to more absorption of heat being retained in the atmosphere thus an increase in global Temperature. Greenhouse gases while largely transparent to incoming solar radiation, absorbs most of the infrared emitted by the earth’s surface.
Water vapor The most abundant greenhouse gas, but importantly, it acts as a feedback to the climate. Water vapor increases as the Earth’s atmosphere warms, but so does the possibility of clouds and precipitation, making these some of the most important feedback mechanisms to the greenhouse effect.
Carbon dioxide (CO2). A minor but very important component of the atmosphere, carbon dioxide is released through natural processes such as respiration and volcano eruptions and through human activities such as deforestation, land use changes, and burning fossil fuels. Humans have increased atmospheric CO2 concentration by 48% since the Industrial Revolution began. This is the most important long-lived “forcing” of climate change.
Methane. A hydrocarbon gas produced both through natural sources and human activities, including the decomposition of wastes in landfills, agriculture, and especially rice cultivation, as well as ruminant digestion and manure management associated with domestic livestock. On a molecule-for-molecule basis, methane is a far more active greenhouse gas than carbon dioxide, but also one which is much less abundant in the atmosphere.
Nitrous oxide. A powerful greenhouse gas produced by soil cultivation practices, especially the use of commercial and organic fertilizers, fossil fuel combustion, nitric acid production, and biomass burning.
Chlorofluorocarbons (CFCs). Synthetic compounds entirely of industrial origin used in a number of applications, but now largely regulated in production and release to the atmosphere by international agreement for their ability to contribute to destruction of the ozone layer. They are also greenhouse gases.
They cause scattering and absorbing the solar and infrared radiation. They change the microphysical and chemical properties of clouds and possibly their lifetime and extent
Half of the land-use change is said to have happened during the industrial era. Most of the forests were replaced by agricultural cropping and grazing of lands. The increased albedo (reflectivity of an object in space) in the snow-covered high altitude regions due to deforestation led to the cooling of the planet’s surface. The lower the albedo, the more of the Sun’s radiation gets absorbed by the planet and the temperatures will rise. If the albedo is higher and the Earth is more reflective, the more of the radiation is returned to space, leading to the cooling of the planet. The tropical deforestation changes the evapotranspiration rates (the amount of water vapour put in the atmosphere through evaporation and transpiration from trees), causes desertification and affects soil moisture characteristics. From the satellite imagery, it is seen that the clearing of forest cover for agriculture and irrigated farming in arid and semi-arid lands can increase solar energy absorption and the amount of moisture evaporated into the atmosphere.
EFFECTS OF GLOBAL WARMING
Flood and landslides: Both causes large death and injury in human population such events are increasing with the global climatic change in countries like Bangladesh, Khartoum, Netherlands, Egypt and Sudan.
Hurricanes and Tornadoes: ocean temperatures increasing due to global warming this subsequently increases the wind speed when maximum wind speed exceeds 74 miles per hour this is called hurricanes in Atlantic and typhoons in pacific. Tornadoes are more frequent in USA and it causes mass destruction to lives, properties and crops.
Droughts: there are four types of droughts such as meteorological (low precipitation), agricultural (lack of moisture for crop growth), hydrological (surface & ground water supply below normal) and socioeconomic (effect in the economy due to water scarcity) such events are common in Sahal and East African countries such as Ethiopia and Sudan.
Forest fires: Are more common in Australia and Indonesia during El-nino events. Forest fires can naturally be ignited by lightening, volcanic eruptions, spark from rock falls and spontaneous combustion. Anthropogenic slash and burn agriculture and exotic / invasive oily plants such as eucalyptus and pine trees naturally cause fires.
Heat waves: heat waves killed more than 2500 people in India (by June 2015). Most affected regions are Andhra Pradesh, Telangana, Punjab, Uttar Pradesh, Odisha and Bihar. It also severely affected cattle and crop production.
Way Ahead : Mention the International and Indian government efforts taken so far in this regard
There are multiple international and national efforts taken so far to reverse this climate change and to mitigate its impact. The United Nations Conference on Environment and Development (UNCED), also known as the ‘Earth Summit’, was held in Rio de Janeiro in 1992. The ‘Earth Summit’ concluded that the concept of sustainable development was an attainable goal for all the people of the world, regardless of whether they were at the local, national, regional or international level.
MITIGATION APPROACHES FOR GLOBAL WARMING
CO2 Mitigation
National Action Plan for Climate Change (NAPCC) is a Government of India’s programme launched in 2008 to mitigate and adapt to the adverse impact of climate change. The plan was drafted to emphasize the overriding priority of maintaining high economic growth rate to raise living standards; the plan “identifies measures that promote our development objectives while also yielding co-benefits for tackling climate change effectively.” It says these national measures would be more successful with assistance from developed countries, and pledges that India’s per capita greenhouse gas emissions “will at no point exceed that of developed countries even as we pursue our development objectives.”
India is a country which is and will be severely impacted by climate variability and change at a time when she is confronted with huge development imperatives. India has already declared that even as she pursues her social and economic development objectives, she will not allow her per capita emission to exceed that of the developed countries. With an economy closely tied to its natural resource base and high dependence on climate sensitive sectors such as agriculture and forestry, India may face a major threat because of the projected changes in climate.
The action plan was launched in 2008 with 8 sub-missions. The plan aims at fulfilling India’s developmental objectives with focus on reducing emission intensity of its economy. The plan will rely on the support from the developed countries with the prime focus of keeping its carbon emissions below the developed economies at any point of time.
THE 8 MISSIONS UNDER NAPCC ARE AS FOLLOWS:-

Answer:
A foreign trade policy outlines a country’s strategies and regulations concerning its international trade activities. It is a comprehensive framework that addresses various aspects, including exports, imports, tariffs, trade agreements, and economic relationships with other nations.
Countries periodically review and update their foreign trade policies to adapt to changing global economic conditions and achieve optimal trade outcomes.
Before the introduction of Foreign Trade Policy (FTP) 2023, FTP 2015-20 was functional. The tenure of FTP 2015-20 had been completed on 31st March, 2020, but owing to the COVID-19 scenario, FTP 2015-20 had been extended up to 31st March, 2023. Thus, the new Foreign Trade Policy 2023 was announced on 31st March, 2023 by the Ministry of Commerce and Industry, Consumer Affairs, Food and Public Distribution and Textiles.
Main features:
Boosting trade:
The FTP 2023 aims at process re-engineering and automation to facilitate ease of doing business for exporters. It also focuses on emerging areas like dual use high end technology items under SCOMET, facilitating e-commerce export, collaborating with States and Districts for export promotion.
The new FTP is introducing a one-time Amnesty Scheme for exporters to close the old pending authorizations and start afresh.
The FTP 2023 encourages recognition of new towns through “Towns of Export Excellence Scheme” and exporters through “Status Holder Scheme”. The FTP 2023 is facilitating exports by streamlining the popular Advance Authorization and EPCG schemes, and enabling merchanting trade from India.
In conclusion, the Foreign Trade Policy (FTP) 2023 of India is a comprehensive framework aimed at boosting exports, promoting ease of doing business, and embracing emerging areas like e-commerce and technology.
The policy reflects a commitment to partnership, technology-driven facilitation, and a robust framework for sustainable export growth.
Question: 28 What is the need of IRNSS (NavIC) for India’s defence sector? Describe its evolution and advantage in detail.
Answer:
NavIC is the operational name of the Indian Regional Navigation Satellite (IRNSS). It is an autonomous regional navigation system, developed by ISRO.
The Need
“Geopolitical needs teach you that some countries can deny you the service in times of conflict. It’s also a way of arm twisting & a country should protect itself against that”
Kargil war, 1999. At the time, India sought the use of U.S owned GPS. Indian military required vital information regarding positioning, navigation & timing [PNT] of hostile forces in Kargil. However, the U.S denied access to the use of GPS in the region. India,after the war, turned to countries that had their own Global Navigation satellite system (GNSS). India entered into negotiations with European Union (EU) for contributing to development of Galileo Satellite Navigation System(SNS), in exchange for reliable data for military use and defence applications. But the negotiations were fruitless. It was due to concerns like availability of sensitive data to other countries & Chinese funding of the project. At last, Russia agreed to provide the necessary data for military use . But , GLONASS (Russia’s GNSS) was unable to provide precise information for use of missiles and weaponry.
In 2009 and 2012, Brahmos failed to hit targets in trial operations. Why? This happened because U.S shut off the GPS satellites without any warning. Due to this, Brahmos’ guiding system got crippled, failing to fulfill it’s objectives. The agonizing experiences made the need for an Indian Navigation Satellite System indispensable
The Inception
In 2006, Indian government gave assent to the project called “Indian Regional Navigation Satellite System”. In totality, 9 satellites has been launched between 2013-2018. These are IRNSS-1A,IRNSS-1B,IRNSS-1C,IRNSS-1D,IRNSS-E,IRNSS-1F,IRNSS-1G,IRNSS-1H & IRNSS-1I. In fact, only 7 satellites are required to complete NavIC constellation. Due to partial failure of IRNSS-1A(failure of Rubidium atomic clocks onboard ) & failed launch of its replacement i.e IRNSS 1H,led to launching of the extra satellites. IRNSS 1I was launched to finally complete NavIC’s constellation. 2 backup satellites are also maintained . The number of operational satellites will be increased to 11 in the future. This will further expand coverage & accuracy .
Advantage
NavIC would be beneficial for regions surrounding INDIA
Conclusion
India has been taking forward leaps in defence manufacturing like Brahmos, LCA, LCH and many more. Navigation is an integral part of such weapon systems. And possessing homemade and reliable satellite navigation system immensely helps Indian Armed forces to become more ‘atmanirbhar’.
