UPSC Prelims 2016 Analysis

Explanation

Net metering (also known as net energy metering) is a solar incentive that allows you to store energy in the electric grid. When your solar panels produce excess power, that energy is sent to the grid and in exchange, you can pull from the grid when your system is under-producing like during night-time.

Explanation

Statement 1 is incorrect. While TEEB is a well-respected initiative, it's not directly hosted by UNEP, IMF, and the World Economic Forum. Germany and the European Commission launched it in response to a proposal by G85 Environment Ministers.

Statement 2 is correct. TEEB's primary goal is to highlight the economic value of biodiversity and ecosystems. It aims to move beyond traditional economic models that often overlook the significant contributions that nature makes to human well-being.

Statement 3 is correct. By providing tools and methodologies, TEEB empowers decision-makers to consider these values when making choices that impact the environment.

Explanation

The Paris Agreement is an agreement within the United Nations Framework Convention on Climate Change (UNFCCC), dealing with greenhouse gas emissions mitigation, adaptation, and finance, starting in the year 2020.

Statement 1 is incorrect. Not all UN member countries signed the Paris Agreement when the question was asked by the UPSC. As of today, 195 parties (194 states and the European Union) have joined.

Statement 2 is correct. The Paris Agreement's central aim is to limit global warming to well below 2 degrees Celsius above pre-industrial levels and to pursue efforts to limit the increase to 1.5 degrees Celsius.

Statement 3 is incorrect. The Paris Agreement acknowledges the historical responsibility of developed countries and calls for them to provide financial assistance to developing countries for climate change mitigation and adaptation. However, the specific amount of $1000 billion per year is not mentioned in the agreement. Rather, $100 billion was agreed upon but modalities are yet to finalise.

Explanation

The great hornbill, also known as the concave-casqued hornbill, great Indian hornbill or great pied hornbill, is one of the larger members of the hornbill family. It occurs in the Indian subcontinent and Southeast Asia. It is predominantly frugivorous, but also preys on small mammals, reptiles and birds.

The great hornbill is native to the forests of India, Bhutan, Nepal, mainland Southeast Asia and Sumatra. Its distribution is fragmented in the Western Ghats and in the foothills of the Himalayas.

Explanation

The Intended Nationally Determined Contributions (INDCs) were submitted by countries before the Paris Agreement (2015) as their initial climate action plans to combat climate change. These documents outlined how each country intended to contribute to global efforts in reducing greenhouse gas (GHG) emissions and adapting to climate impacts.

These were preliminary pledges, meaning they were not legally binding commitments but rather expressions of intent.

Each country independently decided its contribution based on its capabilities, national circumstances, and priorities. Unlike top-down approaches in past climate treaties, INDCs followed a bottom-up approach.

The plans outlined specific measures countries intended to take to reduce greenhouse gas emissions, increase renewable energy use, improve energy efficiency, and adapt to climate change impacts.

Explanation

Statement 1 is correct. Red Sanders, also known as Red Sandalwood or Pterocarpus santalinus, is indeed a tree species native to the southern Eastern Ghats mountain range of India.

Statement 2 is incorrect. It is one of the most important trees in the tropical rainforest areas of South India. Red Sanders is not typically found in tropical rainforests. It grows in drier semi-arid regions of the Eastern Ghats.

Explanation

The Globally Important Agricultural Heritage Systems (GIAHS) initiative was launched by the Food and Agriculture Organization (FAO) in 2002 to identify, safeguard, and promote traditional agricultural systems that have historical, cultural, environmental, and social significance. These systems demonstrate sustainable agricultural practices, rich biodiversity, and resilient rural livelihoods while maintaining a harmonious relationship with nature.

Statement 1 is incorrect: The GIAHS program is not primarily aimed at increasing agricultural productivity through modern methods. Instead, it focuses on preserving traditional farming practices, indigenous knowledge, and sustainable land-use systems that have evolved over centuries. While some modern improvements might be integrated to support local livelihoods, the core emphasis is conservation, not productivity enhancement.

Statement 2 is correct: The primary goal of GIAHS is to identify and protect unique agricultural systems that are vital for global biodiversity, cultural heritage, and food security. This includes preserving traditional landscapes, indigenous crops, and local community knowledge, ensuring their sustainability for future generations.

Statement 3 is incorrect: While some GIAHS products might qualify for Geographical Indication status, it's not an automatic benefit. GI status is granted based on specific criteria related to a product's origin, traditional production techniques, and unique qualities, which require a separate legal recognition process. Hence, the correct answer is option B. 2 only.

Explanation

International Collaboration: Desertification is a global environmental challenge, and the United Nations Convention to Combat Desertification (UNCCD) serves as a key platform for international cooperation. It facilitates the sharing of knowledge, resources, and best practices among countries to develop sustainable solutions for land degradation and desertification.

Local Participation: Communities living in arid and semi-arid regions are the most affected by desertification. These local populations possess traditional ecological knowledge crucial for sustainable land management. The UNCCD actively promotes community involvement in decision-making, policy implementation, and resource management to ensure effective, locally adapted solutions.

While the UNCCD does support efforts in regions highly vulnerable to desertification, such as South Asia and North Africa, its mandate is global, addressing desertification and land degradation worldwide.

Explanation

Drip irrigation is an efficient water delivery system that applies water directly to the roots of plants through a network of tubes, emitters, and valves. It is widely used to conserve water, improve crop yields, and prevent soil degradation.

Statement 1 is correct: Drip irrigation delivers water precisely at the plant's root zone, reducing the moisture available on the soil surface. Since weeds typically thrive in moist topsoil, limiting water exposure to non-target areas helps suppress their growth. This makes weed control easier compared to traditional irrigation methods like flooding or sprinklers, which wet the entire field.

Statement 2 is incorrect: Soil salinity refers to the accumulation of salts in the soil, which can hinder plant growth. While drip irrigation helps manage water efficiently, it does not directly reduce salinity. However, it can be combined with strategic flushing techniques (applying extra water at intervals) to push salts below the root zone, preventing salt buildup in the upper soil layers.

Statement 3 is correct: Drip irrigation releases water slowly and in a controlled manner, reducing surface runoff that can lead to soil erosion. Unlike traditional flood irrigation, which can wash away the topsoil, drip irrigation preserves soil structure and fertility, making it a sustainable choice for agriculture. Hence, the correct answer is option C.

Explanation

The terms mentioned above are all related to the Kyoto Protocol. Here's a brief explanation of each term

Annex-I Countries: These countries have pledged to reduce their emissions by being a part of the Kyoto Protocol.The Cartagena Protocol is a separate international treaty on biosafety.

Certified Emissions Reductions: These are a type of carbon credit that is granted by the Kyoto Protocol for achieving emission reductions through a clean development mechanism project. The Nagoya Protocol is another international treaty focusing on access to genetic resources and the fair and equitable sharing of benefits arising from their utilization.

Clean Development Mechanism: It is a mechanism under the Kyoto Protocol that allows developed countries to invest in emission reduction projects in developing countries as a way to earn emission reduction credits.

The BEE Star Label is a program that promotes energy efficiency in India by labeling appliances and electronic devices based on their energy consumption. Many different categories of appliances are covered under this program

Explanation

The National Mission for Green India (GIM) is one of the eight Missions outlined under the National Action Plan on Climate Change (NAPCC).

Mission Goals

• To increase forest/tree cover to the extent of 5 million hectares (mha) and improve quality of forest/tree cover on another 5 mha of forest/non-forest lands;
• To improve/enhance ecosystem services like carbon sequestration and storage (in forests and other ecosystems), hydrological services and biodiversity; along with provisioning services like fuel, fodder, and timber and non-timber forest produces (NTFPs); and
• To increase forest-based livelihood income of about 3 million households.

Explanation

The Air Quality Index (AQI) is a standardized system for measuring and communicating air pollution levels. It provides a simple scale, ranging from 0 to 500, where higher values indicate worse air quality and greater health risks. The AQI is designed to help the public understand air pollution levels and take necessary precautions.

Unlike a single-pollutant measurement, the AQI considers the concentration of multiple key air pollutants, including:

• Particulate Matter (PM): Tiny airborne particles, including PM2.5 (smaller than 2.5 micrometers) and PM10 (smaller than 10 micrometers). These particles can penetrate deep into the lungs, causing respiratory and cardiovascular issues.
• Ground-level Ozone (O₃): A harmful gas formed by the reaction of pollutants with sunlight. It can irritate the respiratory system, trigger asthma attacks, and reduce lung function.
• Nitrogen Dioxide (NO₂): Emitted from vehicle exhaust and industrial activities, it can cause inflammation of the airways and increase susceptibility to respiratory infections.
• Sulfur Dioxide (SO₂): Released mainly from burning fossil fuels, it can irritate the respiratory tract and lead to lung diseases.
• Carbon Monoxide (CO): A colorless, odorless gas produced by incomplete combustion of fuel. At high concentrations, it can reduce oxygen delivery to the body, leading to serious health effects.

Explanation

Statement 1 is correct: Kharai camels can swim up to three kilometers in seawater. This rare trait allows them to reach offshore mangrove islands, where they forage for food.

Statement 2 is correct: Their name "Kharai" comes from the Gujarati word for "salty" because they primarily graze on saline plants and mangroves. This dietary adaptation allows them to thrive in the harsh coastal environment.

Statement 3 is incorrect: Kharai camels are herded by local communities (Maldhari) in the Kutch region of Gujarat. Their milk is consumed, and male calves are sometimes sold. Hence, the correct answer is option A.

Explanation

Statement 1 is correct. National Ganga River Basin Authority (NGRBA) is the financing, planning, implementing, monitoring, and coordinating authority for the Ganges River, functioning under the Jal Shakti Ministry.

Statement 2 is correct. The mission of the organisation is to safeguard the drainage basin which feeds water into the Ganges by protecting it from pollution or overuse. In July 2014, the NGRBA has been transferred from the Ministry of Environment and Forests to the Ministry of Jal Shakti.

Statement 3 is incorrect. The Prime Minister is the chair of the Authority. Other members include the cabinet ministers of ministries that include the Ganges among their direct concerns and the chief ministers of states through which the Ganges River flows.

Explanation

The Greenhouse Gas (GHG) Protocol is a globally recognized framework for measuring, managing, and reporting greenhouse gas emissions. It was developed through a collaboration between the World Resources Institute (WRI) and the World Business Council for Sustainable Development (WBCSD) to ensure a standardized and transparent approach to GHG accounting.

The protocol helps businesses, governments, and organizations track their emissions consistently, facilitating accurate comparisons across sectors and regions. By providing clear guidelines for carbon accounting, it plays a crucial role in climate action strategies, regulatory compliance, and corporate sustainability efforts worldwide.

Explanation

The first state in India to declare a state butterfly was Maharashtra.

Maharashtra designated the Blue Mormon (Papilio polymnestor) as its state butterfly in 2005. It's a large, black colored butterfly with velvet wings and bright blue spots.

Explanation

The Gadgil Committee Report and the Kasturirangan Committee Report both focus on the conservation of the Western Ghats, one of the world's eight "hottest" biodiversity hotspots.

Gadgil Committee Report (2011) Formally known as the Western Ghats Ecology Expert Panel (WGEEP) Report, this report advocated for strict environmental protection measures across the entire Western Ghats. It recommended designating the entire region as an Ecologically Sensitive Area (ESA), divided into three zones with graded levels of regulation on development activities such as mining, construction, and deforestation. The report emphasized grassroots participation and sustainable development, but its stringent recommendations faced resistance from state governments and industries.

Kasturirangan Committee Report (2012) To review the Gadgil Committee’s recommendations, the High-Level Working Group (HLWG), led by Dr. Kasturirangan, was formed. This report sought a balance between conservation and development by proposing that only 37% of the Western Ghats be designated as ESA, focusing primarily on forest and uninhabited regions while allowing regulated development in other areas. It adopted a more lenient approach than the Gadgil Report, leading to criticism from environmentalists who argued that it diluted the conservation efforts.

In summary, while the Gadgil Report advocated for comprehensive protection with stringent regulations, the Kasturirangan Report took a more moderate stance, allowing some developmental activities while still acknowledging the ecological importance of the Western Ghats.

Explanation

In 1972, Countries met in Stockholm, Sweden, for the United Nations Conference on the Human Environment, to consider the rights of the family to a healthy and productive environment.

In 1983, the United Nations created the World Commission on Environment and Development (later known as the Brundtland Commission), which defined sustainable development as "meeting the needs of the present without compromising the ability of future generations to meet their own needs".

Statement 1 is incorrect. Colombia proposed the idea of the SDGs at a preparation event for Rio20 held in Indonesia in July 2011.

Statement 2 is correct. The Sustainable Development Goals are the blueprint to achieve a better and more sustainable future for all. They address the global challenges we face, including those related to poverty, inequality, climate, environmental degradation, prosperity, and peace and justice. The consensus is that these SDGs have to be achieved by 2030.

Explanation

Statement 1 is correct: The International Solar Alliance (ISA) was launched by India and France on November 30, 2015, during the United Nations Climate Change Conference (COP 21) in Paris. The primary aim of ISA is to promote solar energy deployment, reduce dependence on fossil fuels, and support sustainable energy solutions, particularly in developing countries.

Statement 2 is incorrect: Initially, ISA was open only to 121 solar-rich countries located between the Tropic of Cancer and the Tropic of Capricorn (the "Sun Belt"), as these regions receive abundant solar radiation throughout the year.

However, in 2018, ISA expanded its membership to include all UN member states, allowing countries beyond the tropics to join and benefit from solar energy initiatives. This change made ISA a more inclusive global platform for promoting solar energy adoption worldwide.

Explanation

Statement 1 is correct: Agenda 21 is a comprehensive global action plan adopted at the United Nations Conference on Environment and Development (UNCED), also known as the Rio Earth Summit, held in Rio de Janeiro, Brazil, in 1992. It provides a framework for achieving sustainable development by integrating environmental protection, social equity, and economic growth at global, national, and local levels.

Statement 2 is incorrect: The World Summit on Sustainable Development (WSSD), held in Johannesburg, South Africa, in 2002, reviewed and reaffirmed the commitments made under Agenda 21 but did not introduce it. Instead, the summit focused on assessing progress, strengthening implementation, and launching new initiatives, including the Johannesburg Plan of Implementation (JPOI).

Explanation

Reducing Emissions from Deforestation and Forest Degradation (REDD) attempts to create financial value for the carbon stored in forests, offering incentives for developing countries to reduce emissions from forested lands and invest in low-carbon paths to sustainable development.

REDD goes beyond deforestation and forest degradation, and includes the role of conservation, sustainable management of forests and enhancement of forest carbon stocks. REDD has the potential to simultaneously contribute to climate change mitigation and poverty alleviation, whilst also conserving biodiversity and sustaining vital ecosystem services.

Protection of biodiversity: Forests are incredibly diverse ecosystems, and protecting them through REDD initiatives helps safeguard countless species of plants and animals. Resilience of forest ecosystems: By reducing deforestation and degradation, REDD helps maintain healthy forests that can better withstand natural disturbances like droughts, floods, and pests. Poverty reduction: Many forest communities rely on forests for their livelihoods. REDD programs can provide financial incentives for sustainable forest management, creating income opportunities and alleviating poverty.

Therefore, the correct answer is 1, 2 and 3.
