This agreement delineated specific reduction obligations for different categories of countries, emphasizing market access, domestic support, and export subsidies.
Body:
It is the central part of the answer and one should understand the demand of the question to provide rich content
Market Access:
Provisions concerning market access encompassed tariffication, tariff reductions, and access opportunities. Industrialized nations were mandated to reduce their ordinary tariffs by an average of 36% over a six-year period, with each tariff item subjected to a minimum reduction of 15%. Conversely, developing nations, still grappling with quantitative restrictions due to balance-of-payments concerns, were permitted to offer ceiling bindings instead of tariffs.
Domestic Support:
Regarding domestic support measures, which were subject to reduction commitments, affluent nations were required to curtail overall support provided during 1986-88 by 20%, while developing countries faced a reduction of 13.3%. Certain policies falling under domestic support categories, constituting less than 5% of the value of production for developed countries and less than 10% for developing nations, were exempt from reduction commitments.
Export Subsidies:
The Agreement mandated reductions in export subsidies, with developed countries tasked with slashing export subsidy expenditure by 36% and volume by 21% over six years, based on 1986-1990 levels. Similarly, developing countries were required to make cuts of 24% and 14%, respectively, over a decade. Furthermore, the Agreement prohibited future subsidies for products not subject to export subsidy reduction agreements.
Conclusion:
The ending of the answer should be on a positive note and it should have a forward-looking approach

It is the central part of the answer and one should understand the demand of the question to provide rich content
Methodology:
The fifth cycle of leopard population assessment in India (2022) focused on forested habitats across 18 tiger states, encompassing four significant tiger conservation landscapes. Utilizing a likelihood-based spatially explicit capture mark-recapture (SECR) covariate model, researchers combined photo-captures with geographical data on prey, habitat, and human-induced factors to estimate leopard abundance.
Phase 1:
Systematic sampling of wooded regions within each landscape was conducted using M-STrIPES Android apps and desktop applications.
Phase 2:
Remote sensing and secondary data were employed to model leopard occupancy and abundance in response to habitat factors and human influences.
Phase 3:
SECR models were utilized to predict leopard density through camera trap data, with individuals identified using image and pattern processing applications such as CaTRACT and ExtractCompare.
Outcomes:
Madhya Pradesh boasts the highest leopard count in the country, with 3,907 individuals (up from 3,421 in 2018). Central India harbors the most significant population, comprising 8,820 leopards, followed by the Western Ghats with 3,596, and the Shivalik Hills and Gangetic Plains with 1,109 individuals. Population growth rates varied across regions, with a decline observed in the Shivalik Hills and Gangetic Plains, while other regions experienced moderate increases.
In Central India, a substantial proportion (68%) of leopards reside in human-use forests outside Protected Areas, heightening vulnerability to poaching and human-leopard conflicts. Similarly, in the Western Ghats, although leopard populations remain stable, a significant portion (65%) inhabits areas outside Protected Areas.

Introduction:
Traditionally, the measurement of poverty has relied on income levels or, in the absence of income data, expenditure levels. These indicators, known as "poverty lines," represent expenditure levels considered low enough to categorize an individual as impoverished. In India, multidimensional poverty witnessed a decline from 29.17% in 2013-14 to 11.28% in 2022-23, leading to approximately 24.82 crore individuals escaping poverty during this period. Notably, Uttar Pradesh emerged as the state with the highest number of people escaping poverty at 5.94 crore, followed by Bihar at 3.77 crore and Madhya Pradesh at 2.30 crore.
Body:
A divergence exists between the Indian Multidimensional Poverty Index (MPI) and the Global MPI. Globally, the MPI employs 10 indicators across three primary domains: (i) health, (ii) education, and (iii) standard of living. Each of these dimensions holds equal weight, contributing one-third to the final index. Health indicators encompass child and adolescent mortality, education metrics include years of schooling and attendance, and the standard of living dimension incorporates household-specific indicators like housing, household assets, cooking fuel type, sanitation, drinking water, and electricity.
The Indian MPI, while aligning with global dimensions, incorporates two additional indicators to reflect national priorities. These additional indicators cover maternal health under the health dimension and bank accounts under the standard of living dimension, according to the NITI Aayog.
Conclusion:
The Multidimensional Poverty Index (MPI) value for a given population is the proportion of weighted deprivations faced by individuals experiencing multidimensional poverty divided by the total population. This nuanced approach to measuring poverty, considering multiple dimensions beyond income, provides a comprehensive understanding of the challenges individuals face in different aspects of their lives

Introduction:
The objective of creditisation is to establish academic parity between vocational and general education, fostering seamless transition between these two educational systems, as outlined in the National Education Policy (NEP) of 2020. In line with this, the University Grants Commission (UGC), responsible for overseeing higher education, introduced the National Credit Framework (NCrF) in 2022 to operationalize this vision. NCrF serves as a unified credit framework aimed at integrating training and skill development into both school and higher education, with student credits digitally stored in the Academic Bank of Credits and accessible through linked Digilocker accounts.
Body:
The proposed changes recommended by the Central Board of Secondary Education (CBSE) subcommittee underscore the absence of a formalized credit system in the current standard school curriculum. According to the CBSE plan, an academic year would consist of 1,200 notional learning hours, equating to earning 40 credits. These hours encompass both academic learning within the school setting and non-academic or experiential learning outside the school premises.
To implement this, adjustments have been made to the scheme of studies, outlining teaching hours and credits earned for each subject. The committee advocates the inclusion of multidisciplinary and vocational courses alongside existing disciplines. Consequently, to pass final exams in Classes 9 and 10, students must complete ten subjects, comprising three languages and seven core disciplines.
Furthermore, the proposal suggests that at least two of the three mandatory languages should be Indian, providing flexibility in language choices such as Hindi, Sanskrit, and English. For Classes 11 and 12, the Board recommends students study six subjects, encompassing two languages and four subjects with an optional fifth. At least one of the two languages must be Indian.
Conclusion:
The Central Board of Secondary Education (CBSE), the largest national school board in the country, is poised to implement substantial modifications to the academic framework for Classes 9, 10, 11, and 12. This initiative aligns with the creditisation approach advocated by the 2020 National Education Policy (NEP), reflecting a commitment to establishing equivalence between vocational and general education

A recent study, published in April of this year in the Agronomy Journal, highlights the transformation of India's primary pearl millet (bajra) production areas. Between 1998 and 2017, these zones have shifted to encompass 18 districts located across eastern Rajasthan and Haryana. The research was a collaboration between the International Crops Research Institute for the Semi-arid Tropics (ICRISAT) and the Indian Council of Agricultural Research – All India Coordinated Research Project on Pearl Millet (ICAR-AICRP).
This alteration in cultivation zones has been attributed to an increase in rainfall induced by human-driven climate change. In India, pearl millet cultivation areas are traditionally classified based on precipitation patterns and soil types:
(i) Zone A1 – Arid Zone of Rajasthan (less than 400 mm rainfall) (ii) Zone A – Semi-arid regions in north and central India (more than 400 mm rainfall) – Rajasthan, Haryana, Gujarat, and Uttar Pradesh (iii) Zone B – Southern and central western India
The study further divides Zone 'A' into three subzones: 'G', 'AE1', and 'AE2'. Zone 'G' witnessed an average increase in rainfall in Gujarat, while Zone 'AE1' experienced a rise in eastern Rajasthan and Haryana. Additionally, Zone 'AE2' covers 12 districts in Uttar Pradesh and Madhya Pradesh.
Conclusion
In India, millets are predominantly cultivated during the kharif season. As per Agriculture Ministry data for 2018-19, three millet crops—bajra (3.67%), jowar (2.13%), and ragi (0.48%)—comprised approximately 7 percent of the total cultivated area in the country.
Millets are renowned for being nutritional powerhouses. Buckwheat (kuttu) and amaranth (chaulai), categorized as pseudo millets due to their substantial nutritional value, are now recognized as "Nutri Cereals" for production, consumption, and trade.

A simple introduction to this answer can revolve around a general statement about Sahara Desert.
The Sahara desert covers an area of around 9,200,000 square kilometres and is one of the largest hot deserts in the world.
Deserts are defined by low average annual rainfall — usually 100 millimeters (less than 4 inches) of rain per year or less.
The cyclic transformation of the Sahara Desert into savannah and woodland ecosystems is one of the most remarkable environmental changes on the planet.
According to the research study that was published in the journal Nature Communications, the periodic wet phases in the Sahara desert were caused by changes in Earth’s orbit around the Sun
Body
You may incorporate some of the following points in the body of your answer:
Possible Reasons
Increase in the African Humid period which could have allowed the dispersal of various species.
There is already a lot of evidence to back up the hypothesis that the Sahara was once vegetation. These “North African humid periods” may have had a significant influence in the establishment of vegetation passageways out of Africa.
The greenings of the Sahara Desert could have been driven by changes in Earth’s orbital precession.
The Earth’s spin influences seasonality over an approximately 21,000-year cycle. The changes in precession also decide the amount of energy received by the planet during different seasons.
These changes caused warmer summers in the Northern hemisphere and thereby increased the strength of the West African monsoon system which has increased rain in the Sahara, causing the spread of savannah-type vegetation through the desert.
Conclusion
You can add a simple conclusion like the following
Sahara's transformation is a topic of ongoing research, and our understanding of the mechanisms involved continues to evolve. Additionally, human-induced climate change may be influencing the Sahara's climate in ways that are not fully understood. Studying past climate records, modeling future scenarios, and monitoring current conditions are essential for gaining a more comprehensive understanding of the complex processes involved in the transformation of the Sahara Desert into savannah and woodland ecosystems.

Measures to Reduce Methane Emissions
India has been persistent in its commitment to developing and implementing climate change policies. The following are ongoing attempts to limit methane emissions:
National Mission on Sustainable Agriculture (NMSA): It involves climate-resilient practices such as methane reduction in rice agriculture which helps to significantly reduce methane emissions.
National Innovations in Climate Resilient Agriculture (NICRA) project: The Indian Council of Agricultural Research (ICAR) has developed several technologies with mitigation potential for methane from rice viz.
(a) System for Rice Intensification: The technique has potential to enhance rice yield from 36-49% with about 22-35% less water than conventional transplanted rice;
(b) Direct Seeded Rice: The system reduces methane emissions as it does not involve raising nurseries, puddling and transplanting. Unlike transplanted paddy cultivation, standing water is not maintained in this system and
(c) Crop Diversification Programme: Methane emissions is avoided due to diversion of paddy to alternate crops like pulses, oilseeds, maize, cotton and agroforestry.
Capacity-building programmes are conducted through Krishi Vigyan Kendras across the country to create awareness on climate-resilient practices.
National Livestock Mission: It includes Breed Improvement and Balanced Rationing. Feeding better quality balanced rations to animals helps to minimise methane emissions from livestock. The Government of India also promotes for green fodder production, silage making, chaff cutting, and total mixed ration.
