Climate, Environment & Disasters Current

Introduction

This subtopic lies at the intersection of global environmental governance, climate science, disaster risk management, and the institutional architecture that underpins international cooperation. For the UPSC aspirant, "Climate, Environment & Disasters Current" is not merely a repository of static facts—it is a dynamic arena where treaties, summits, financial mechanisms, and national policies evolve rapidly. The Union Public Service Commission tests this area to assess a candidate's ability to connect global developments with India’s domestic priorities, evaluate the effectiveness of multilateral frameworks, and discern the operational nuances of environment-related platforms.

Between 2018 and 2025, six questions from this subtopic have appeared in the UPSC Preliminary Examination. They span a range of difficulty: factual recall (e.g., where the Partnership for Action on Green Economy emerged), description-based identification (e.g., the correct description of “100 Million Farmers”), and analytical statement verification (e.g., statement-based questions on report implications). The common thread is that UPSC favours operational details—not just the name of a summit, but the specific year and venue; not just the existence of a platform, but its exact mission statement. The 2025 paper, in particular, showed a shift towards multi-statement reasoning, requiring candidates to weigh which statements correctly explain a given premise.

This chapter is designed to equip you with everything you need to master this subtopic. We begin with foundational concepts—green economy, sustainable development, nature-based solutions, climate finance—building from first principles so that no term remains jargon. Then we dive into three topic-specific deep-dives rooted in the actual PYQs: the Partnership for Action on Green Economy (2018), the Nature Solutions Finance Hub (2025), and the 100 Million Farmers platform (2024). Each section weaves in the tested facts while expanding into adjacent knowledge that is ripe for future examination. Worked examples show exactly how to dissect UPSC-style questions. A trends analysis reveals the Commission’s favourite framing patterns, and a forward-looking table predicts five to eight likely question angles. Finally, memory aids, common traps, and a bullet-point revision checklist ensure you walk into the exam hall with confidence.

Core Concepts & Foundations

Before tackling specific PYQs, you must internalise the conceptual toolkit that UPSC assumes you possess. Every term below appears directly or indirectly in the tested questions. Each definition is given as a blockquote – treat these as your anchor points.

Green Economy: An economy that aims to reduce environmental risks and ecological scarcities while improving human well-being and social equity. It is characterised by low carbon emissions, resource efficiency, and social inclusiveness. The concept gained global traction at the Rio+20 Conference (2012) and is promoted through mechanisms like PAGE.

Sustainable Development: Development that meets the needs of the present without compromising the ability of future generations to meet their own needs (Brundtland Commission, 1987). It rests on three pillars: economic growth, social inclusion, and environmental protection. The 2030 Agenda for Sustainable Development (2015) operationalises this through 17 SDGs.

Nature-Based Solutions (NbS): Actions that protect, sustainably manage, and restore natural or modified ecosystems to address societal challenges such as climate change, water security, food security, and disaster risk. NbS are distinct from purely technological fixes because they leverage ecological processes. The Nature Solutions Finance Hub (tested in UPSC 2025) is an NbS-specific funding platform.

Climate Finance: Local, national, or transnational financing—drawn from public, private, and alternative sources—that supports mitigation and adaptation actions to address climate change. Key institutions include the Green Climate Fund (GCF), the Global Environment Facility (GEF), and regional development banks like the Asian Development Bank (ADB) (tested in 2025).

Net-Zero (Carbon): A state where human-caused greenhouse gas emissions are balanced by removals over a specified period. Net-zero targets are now central to national climate pledges (NDCs) under the Paris Agreement. The “100 Million Farmers” platform (tested in 2024) explicitly aims for net-zero food and water systems.

Nature-Positive: A goal that aims to halt and reverse nature loss by 2030, measured against a 2020 baseline. It complements net-zero carbon by addressing biodiversity decline. The phrase appears in the “100 Million Farmers” description and is increasingly used in global biodiversity frameworks (e.g., the Kunming-Montreal Global Biodiversity Framework).

Farmer Resilience: The capacity of farming communities to anticipate, withstand, and recover from shocks—climatic, economic, or social—while maintaining productivity and ecosystem services. Platforms like “100 Million Farmers” bundle digital tools, finance, and knowledge-sharing to enhance this resilience.

Multilateral Environmental Agreements (MEAs): Binding or non-binding treaties among multiple nations to address transboundary environmental issues. Examples include the UN Framework Convention on Climate Change (UNFCCC, 1992), the Convention on Biological Diversity (CBD, 1992), and the UN Convention to Combat Desertification (UNCCD, 1994). The Rio+20 Conference (2012) is not an MEA but a summit that shaped subsequent agreements.

United Nations Conference on Sustainable Development (UNCSD) 2012: Also known as Rio+20, this conference was held in Rio de Janeiro, Brazil, 20 years after the original Earth Summit. It produced the outcome document “The Future We Want” and launched the process to develop the Sustainable Development Goals (SDGs). Crucially for UPSC, it also launched the Partnership for Action on Green Economy (PAGE) (tested in 2018).

Asian Development Bank (ADB): A regional development bank established in 1966, headquartered in Manila, Philippines. It focuses on poverty reduction and sustainable development in Asia and the Pacific. In 2025, the ADB launched the Nature Solutions Finance Hub for Asia and the Pacific (tested in UPSC 2025). The hub is designed to scale up investments in nature-based solutions, blending public and private capital.

These concepts are not isolated—they interact. A green economy requires climate finance to fund NbS, which in turn builds farmer resilience. A multilateral MEA like the UNFCCC sets the target (net-zero), and platforms like PAGE help countries implement the transition. Understanding these linkages is what UPSC rewards.

Core Principles: How Green Economy, SDG, and NbS Relate

The table below compares three overlapping frameworks that frequently appear in UPSC questions. Knowing their distinctions prevents confusion in statements-based questions.

Key insight for aspirants: UPSC often tests the launch venue and the exact mission statement of these initiatives. Never confuse Rio+20 (2012) with the Earth Summit (1992) or the Paris Conference (2015). PAGE emerged at Rio+20; the Green Climate Fund was established at COP 16 (2010) and formally launched at COP 17 (2011); the Paris Agreement was adopted in 2015.

Global Environmental Governance: Summits and the PAGE Question

The first deep-dive section focuses on the institutional landscape that gave birth to the Partnership for Action on Green Economy (PAGE). In UPSC 2018, the question asked: “The Partnership for Action on Green Economy (PAGE), a UN mechanism to assist countries transition towards greener and more inclusive economies, emerged at …” The correct answer: The United Nations Conference on Sustainable Development 2012, Rio de Janeiro. This is a classic factual recall question, but the underlying knowledge required is much richer.

The Evolution of UN Environment Summits

Understanding why Rio+20 is the correct venue requires a brief history of UN environmental conferences. The first major global summit was the UN Conference on the Human Environment (Stockholm, 1972), which established the UN Environment Programme (UNEP). Twenty years later, the Earth Summit (Rio de Janeiro, 1992) produced the three Rio Conventions (UNFCCC, CBD, UNCCD) and Agenda 21. Another twenty years on, Rio+20 (2012) aimed to assess progress and renew political commitment. It was at Rio+20 that the idea of a formal partnership to operationalise green economy took concrete shape—PAGE.

Why wasn’t the Earth Summit 2002 in Johannesburg the correct answer? The 2002 Summit (World Summit on Sustainable Development) had its own outcomes (e.g., the Johannesburg Plan of Implementation) but did not launch PAGE. Similarly, the Paris Climate Conference (COP21, 2015) focused narrowly on climate change, not on an inclusive green economy partnership. The World Sustainable Development Summit in New Delhi is an annual event, but it is not a UN mechanism and did not launch PAGE.

PAGE: Structure and Functions

PAGE (Partnership for Action on Green Economy): A partnership founded in 2013 (following the Rio+20 mandate) by five UN agencies: UNEP, ILO, UNIDO, UNDP, and UNITAR. It provides technical assistance and capacity-building to countries seeking to implement green economy policies. As of 2025, over 40 countries have received PAGE support. Its four thematic pillars are: green jobs, green trade, green finance, and green procurement.

For UPSC, you must remember that PAGE is a cross-agency UN partnership, not a stand-alone treaty. It emerged from the Rio+20 outcome document “The Future We Want,” paragraph 62, which recognised green economy as a tool for sustainable development. The “Partnership” in its name is crucial—it is not an organisation but a coordination mechanism.

Adjacent Initiatives to Know

Given that PAGE was tested in 2018, UPSC may later ask about similar green-economy platforms. Key ones include:

• Green Growth Knowledge Partnership (GGKP): A global network of researchers and practitioners focused on green growth—distinct from PAGE’s emphasis on inclusive green economy.
• GGGI (Global Green Growth Institute): An intergovernmental organisation founded in 2012, based in Seoul, that works with developing countries on green growth planning.
• UNEP’s Green Economy Initiative: Launched in 2008, it provided the conceptual underpinning for PAGE.

Memory Aid for PAGE Launch: P = Partnership, A = After Rio+20 (2012), G = Green, E = Economy. The year: 2013. Remember “PAGE” as “Post Action from Green Earth” (linking to Rio+20 where “The Future We Want” was the action document).

Climate Finance and Nature-Based Solutions: The ADB Hub

The second deep-dive is anchored in the UPSC 2025 question: “Which one of the following launched the Nature Solutions Finance Hub for Asia and the Pacific?” The correct answer: The Asian Development Bank (ADB). This question tests knowledge of a very current initiative—the hub was launched in 2024/2025. Understanding why ADB is the correct answer requires familiarity with the bank’s role in regional green finance and its existing nature-positive portfolio.

The Nature Solutions Finance Hub

The Nature Solutions Finance Hub (NSFH) is a regional financing platform that aims to mobilise private and public capital for nature-based solutions in Asia and the Pacific. Announced at COP28 in Dubai (2023) and formally launched in 2024, the hub is hosted by the ADB and is part of its “Green and Blue Economy” strategy. The hub’s specific focus is on projects that restore ecosystems (mangroves, forests, wetlands) while generating economic returns and reducing climate risk.

Why AIIB, NDB, and IBRD are wrong:

• Asian Infrastructure Investment Bank (AIIB): Focused on infrastructure—energy, transport, urban development—not specifically nature-based solutions. It has a Climate Action Plan but no dedicated NbS hub for Asia.
• New Development Bank (NDB): Formerly BRICS Bank, focuses on infrastructure and sustainable development, but its regional scope is global (BRICS nations) and it has not launched a dedicated Asia-Pacific NbS hub.
• International Bank for Reconstruction and Development (IBRD): Part of the World Bank Group; it finances NbS globally but the hub for Asia and the Pacific is specifically an ADB initiative.

The Funding Landscape for Nature-Based Solutions

The NSFH is one of several mechanisms. A comparison helps you differentiate them in exam questions:

Key insight for aspirants: For each financial mechanism, remember: (1) who launched it, (2) what it specifically funds, (3) when and where it was launched. The ADB hub is unique because it is regional (Asia-Pacific) and explicitly targets “Nature Solutions” (a synonym for NbS). UPSC could test other regional hubs, e.g., the Amazon Fund (under BNDES) or the Central African Forest Initiative (CAFI).

India’s Engagement with ADB on Nature Solutions

India is a major borrower from the ADB. In 2024, ADB approved a $250 million loan for climate-resilient agriculture in the state of Madhya Pradesh, which aligns with the NSFH’s mandate. India has also launched its own National Adaptation Fund for Climate Change (NAFCC) and the Green India Mission (GIM) under the National Action Plan on Climate Change (NAPCC). UPSC may ask about complementarities between global hubs and domestic funds.

Agricultural Transformation and Farmer Resilience: The “100 Million Farmers” Platform

The third deep-dive centres on the UPSC 2024 question: “Which one of the following is the correct description of ‘100 Million Farmers’?” Correct answer: “It is a platform for accelerating the transition towards food and water systems that are net-zero (carbon), nature-positive and that aims to increase farmer resilience.” This question tests the candidate’s ability to recognise a precise mission statement and to distinguish it from other farming initiatives.

What Is “100 Million Farmers”?

100 Million Farmers: A multi-stakeholder platform launched at COP28 (2023) in Dubai by the World Business Council for Sustainable Development (WBCSD), together with partner organisations. Its goal is to mobilise $10 billion in public-private finance to help 100 million farmers worldwide adopt regenerative, climate-smart practices. The platform is not a single digital tool but a coalition that provides technical assistance, market access, and finance.

The platform’s key components include:

• Net-zero carbon in food and water supply chains.
• Nature-positive outcomes (biodiversity enhancement, soil health).
• Farmer resilience through diversified income and risk management.
• Digital tools (remote sensing, blockchain for traceability) but the platform is broader—it is not just a digital trading platform.

Why the Other Choices Are Wrong

The three incorrect descriptions that students saw were:

1. “It is an international alliance and a network of individuals and farming organisations interested in supporting and strengthening the development of organic animal husbandry.” → This describes an organic livestock network, not the integrated food-water-carbon platform of 100 Million Farmers.

2. “It is a digital platform fully integrated with service providers and built on blockchain that lets buyers, sellers and third parties trade fertilizers quickly and securely.” → This is a fertiliser trading platform, possibly akin to an e-marketplace, but 100 Million Farmers is not focused on fertiliser trading.

3. “It is a platform with the mission of encouraging the farmers to form Farmer Producer Organisations or Agribusiness Consortiums, thus facilitating them to sell along to global open markets to sell their products.” → This describes a typical FPO promotion scheme, not the net-zero, nature-positive ambition of 100 Million Farmers.

The correct description is precise in its language: “net-zero (carbon), nature-positive, and farmer resilience.” This phrasing mirrors the platform’s official tagline.

Comparison of Agriculture Transformation Platforms

UPSC may test multiple agriculture-related global initiatives. The table below contrasts three prominent ones.

Key insight for aspirants: The phrase “net-zero (carbon)” and “nature-positive” are hallmark signals of the post-2020 global framework under the Paris Agreement and the Kunming-Montreal Global Biodiversity Framework (GBF). Any platform aiming for both carbon neutrality and biodiversity restoration will use these terms. Look for them in UPSC questions.

India’s Domestic Equivalent

India’s National Mission for Sustainable Agriculture (NMSA) and the Pradhan Mantri Krishi Sinchayee Yojana (PMKSY) aim to improve water-use efficiency and climate resilience, but they do not explicitly use the term “nature-positive.” The Zero Budget Natural Farming (ZBNF) movement in Andhra Pradesh has been promoted as a nature-positive approach, but it is not a global platform. In 2025, the Indian government launched the “Climate-Resilient Agriculture Initiative” as part of the NAPCC. Watch for cross-linking: UPSC may ask “Which global platform inspired or partners with India’s latest agriculture scheme?” The answer could be 100 Million Farmers.

Worked Examples & Applications

This section walks through three PYQs from the input that have full question text. For each, we dissect exactly how to arrive at the correct answer.

Example 1 — UPSC 2018

Question: The Partnership for Action on Green Economy (PAGE), a UN mechanism to assist countries transition towards greener and more inclusive economies, emerged at

Choices students saw:

• The United Nations Conference on Sustainable Development 2012, Rio de Janeiro
• The Earth Summit on Sustainable Development 2002, Johannesburg
• The United Nations Framework Convention on Climate Change 2015, Paris
• The World Sustainable Development Summit 2016, New Delhi

Walkthrough:

1. What the question is testing: Factual recall of the launch venue of a specific UN multi-agency partnership. The keywords are “Partnership for Action on Green Economy”, “emerged at”, and the need to identify the correct summit.
2. Why each wrong choice is wrong:
   • Earth Summit 2002, Johannesburg: This summit (WSSD) focused on sustainable development implementation, but PAGE did not exist then; PAGE was a direct outcome of Rio+20.
   • UNFCCC 2015, Paris: Paris COP21 adopted the Paris Agreement on climate change. PAGE is not a product of COP21—it’s not specifically about climate change but about green economy (broader).
   • World Sustainable Development Summit 2016, New Delhi: An annual event by TERI, not a UN mechanism and not the launch site of PAGE.
3. Why the correct choice is right: Rio+20 (UNCSD 2012) produced the outcome document “The Future We Want,” which called for a green economy partnership. PAGE was subsequently launched in 2013, hosted by UNEP and four other UN agencies. The phrase “emerged at” refers to the conference where the political mandate was given.

Correct answer: The United Nations Conference on Sustainable Development 2012, Rio de Janeiro.

Takeaway: Memorise the exact year and venue for each major summit and the key initiatives born there. Rio+20 gave us PAGE; the Earth Summit 1992 gave us the three Rio Conventions; Paris 2015 gave us the Paris Agreement.

Example 2 — UPSC 2025

Question: Which one of the following launched the ‘Nature Solutions Finance Hub for Asia and the Pacific’?

Choices students saw:

• The Asian Development Bank (ADB)
• The Asian Infrastructure Investment Bank (AIIB)
• The New Development Bank (NDB)
• The International Bank for Reconstruction and Development (IBRD)

Walkthrough:

1. What the question is testing: Knowledge of which multilateral development bank (MDB) specifically launched a regional nature-based solutions financing hub. The hub’s name includes “for Asia and the Pacific,” indicating a regional focus.
2. Why each wrong choice is wrong:
   • AIIB: Infrastructure-focused lender; no dedicated NbS hub for the region.
   • NDB: BRICS-led global bank; its mandate is not specifically Asia-Pacific and no such hub announced.
   • IBRD: Part of World Bank; while it supports NbS globally, the Asia-Pacific regional hub is not its initiative.
3. Why the correct choice is right: The ADB has a strong presence in Asia-Pacific, has been increasing its climate finance portfolio (target of $100 billion by 2030), and in 2024 launched the Nature Solutions Finance Hub to accelerate private investment in nature-based projects.

Correct answer: The Asian Development Bank (ADB).

Takeaway: For any new initiative involving a “hub” or “facility,” note which institution launched it and the geographic focus. The ADB is the leading MDB for Asia-Pacific climate and nature finance.

Example 3 — UPSC 2024

Question: Which one of the following is the correct description of ‘100 Million Farmers’?

Choices students saw:

• It is an international alliance and a network of individuals and farming organisations interested in supporting and strengthening the development of organic animal husbandry.
• It is a digital platform fully integrated with service providers and built on blockchain that lets buyers, sellers and third parties trade fertilizers quickly and securely.
• It is a platform with the mission of encouraging the farmers to form Farmer Producer Organisations or Agribusiness Consortiums, thus facilitating them to sell along to global open markets to sell their products.
• It is a platform for accelerating the transition towards food and water systems that are net-zero (carbon), nature-positive and that aims to increase farmer resilience.

Walkthrough:

1. What the question is testing: The ability to match a platform description to its official mission statement. The key phrases are “net-zero (carbon)”, “nature-positive”, and “farmer resilience”. No other choice contains these specific terms.
2. Why each wrong choice is wrong:
   • Organic animal husbandry: Too narrow; 100 Million Farmers covers crops, water, and carbon, not just livestock.
   • Digital platform for fertiliser trading: Incorrect; the platform is not about trading fertilisers but about holistic farm system transformation.
   • FPO/Agribusiness consortium formation: This describes a common agricultural policy instrument, not the globally ambitious, carbon-focused platform.
3. Why the correct choice is right: The fourth choice directly quotes the platform’s own language: “accelerating the transition,” “net-zero (carbon),” “nature-positive,” and “farmer resilience.” WBCSD’s official documents use these exact words.

Correct answer: It is a platform for accelerating the transition towards food and water systems that are net-zero (carbon), nature-positive and that aims to increase farmer resilience.

Takeaway: When UPSC asks for a description of a named initiative, look for the distinctive multi-word phrase that includes technical terms like net-zero, nature-positive, resilience. Attacks often include plausible but narrower descriptions.

PYQ Trends & Patterns

The six PYQs from this subtopic (2018, 2021, 2024, 2025) reveal a clear trajectory in UPSC’s thinking. Here is a meta-analysis.

Year-wise distribution and difficulty:

• 2018: Single factual recall (PAGE venue). Easy to moderate.
• 2021: Statement-based question with three statements, correct answer being two statements. Requires both recall and logical elimination. Moderate.
• 2024: Description identification (100 Million Farmers). Requires close reading of official language. Moderate.
• 2025: Two questions: one factual (ADB hub) and one statement-implication analysis. The analytical question (Q5 and Q6 in the input) involved evaluating which statements best reflect a report’s implication and which combination explains a given statement. This is a jump in difficulty—candidates must not only know facts but also understand how claims relate to each other.

Question type split:

• Factual (who launched, where emerged): 3 questions
• Description matching: 1 question
• Statement verification / implication analysis: 2 questions

Sub-topic concentration:

• Institutions and platforms: PAGE, ADB hub, 100 Million Farmers – pure environment-development nexus.
• Agriculture & food systems: 100 Million Farmers.
• Climate finance: ADB hub.
• Summits & conferences: PAGE (Rio+20).
• Report implications: Q5 and Q6 (2025) – likely related to a climate/environment report (e.g., IPCC, UNEP Emissions Gap Report, etc.), though the exact report is not given in the input. The pattern suggests UPSC is increasingly testing the ability to interpret findings.

Recurring traps: Confusing similar-sounding banks (ADB vs AIIB), confusing summits (Rio+20 vs Earth Summit 1992), misremembering launch years, and wrongly attributing platforms to lead organisations.

Future trajectory: Expect more statement-based and implication-analysis questions, especially linking a newly launched initiative to an existing report or treaty. Also, expect matching questions (match initiative with description or launching body) as seen in 2024 and 2025.

What Else Could Be Asked

Based on the PYQs above, we can predict several adjacent questions that UPSC may ask in upcoming exams. The following table lists five to eight concrete forecasts, each anchored in what has already been tested.

Flavour analysis:

• Depth extension: Understanding the specific pillars of PAGE (green jobs, green trade, green finance, green procurement) or the exact financing instruments under the ADB hub (e.g., green bonds, blended finance).
• Lateral extension: Studying other green economy partnerships (GGKP, GGGI), other MDB hubs (World Bank’s “Accelerating NbS” program), and other agriculture platforms (Regen10, Coalition for Food and Land Use).
• Combinatorial extension: Match-the-following questions where a list of five initiatives is paired with five lead organisations or five launch summits.

Common Mistakes & Traps

Based on the PYQs and common student errors, here are specific traps to avoid:

• Confusing Rio+20 (2012) with the Earth Summit (1992). The Earth Summit gave us the Rio Conventions; Rio+20 gave us PAGE and the SDG process. Many aspirants remember “Rio” and automatically think 1992. Always check the context: “Partnership for Action on Green Economy” is post-2012.
• Mixing up ADB and AIIB. Both are multilateral banks in Asia. ADB was founded in 1966, AIIB in 2016. AIIB focuses on infrastructure; ADB also finances infrastructure but has a much broader environment and nature portfolio. The “Nature Solutions Finance Hub” is ADB’s; remember “Nature” is ADB’s tag (they have a “Nature Solutions” department).
• Assuming “100 Million Farmers” is a UN initiative. It was launched by the World Business Council for Sustainable Development (WBCSD), a CEO-led coalition. UPSC loves to test which type of organisation launches a platform—private sector, intergovernmental, or civil society.
• Ignoring the specific wording in description questions. In the 2024 question, three wrong choices each described a real initiative (organic animal husbandry network, fertiliser blockchain platform, FPO promotion). A candidate who only reads part of the description may pick the organic animal husbandry one because it sounds “green.” Always scan for the distinctive technical terms: net-zero, nature-positive.
• Overlooking the exact event name. “UNCSD 2012” is the official name; some texts call it “Rio+20.” Both are acceptable, but the year is non-negotiable. If a question asks “emerged at,” it could be the conference or the specific outcome document—but the conference is the correct answer as seen.
• Misinterpreting “statement implication” questions. In 2025, Q5 and Q6 required analysing which statements are implied by a report and which statements explain the main statement. The trap is to treat all statements as independent facts. Instead, read them as logical claims: does Statement II cause or justify Statement I? If a statement merely restates the report’s conclusion, it may be correct but not explanatory. Always separate “factually correct” from “explanatorily correct.”

Memory Aids & Mnemonics

Two practical mnemonics to lock in the most frequently tested sequences.

Mnemonic 1: “PAGE – 4G” for the four priority areas of PAGE

• P
• A
• G
• E

Break the word PAGE into its initials and assign a “G” word for each letter:

• P – Programs for Green Jobs
• A – Action on Green Trade
• G – Guidance on Green Finance
• E – Expertise on Green Procurement

The phrase “4G” stands for the four thematic pillars: Green Jobs, Green Trade, Green Finance, Green Procurement. (Note: “Green Procurement” is sometimes called sustainable procurement; the acronym remains.)

What it unlocks: When UPSC asks “which of the following is NOT a pillar of PAGE?” or “which pillar relates to job creation?”, you can recall P-A-G-E.

Worked example: Question: Under PAGE, which pillar focuses on creating environmentally-friendly employment? → Answer: Green Jobs (Pillar P). Using the mnemonic, P is the first letter of “PAGE” and corresponds to “Programs for Green Jobs”.

Mnemonic 2: “StoRioRio” for the three major UN environment summits

Story-chain: Imagine a pot (STOck) of water, a river (RIo), and another river (RIo). The first summit was Stockholm (1972), the second was Rio (1992), the third was Rio+20 (2012). So the sequence: Sto-Rio-Rio. To remember the years: 1972, 1992, 2012 (each 20 years apart). The gap is 20 years.

What it unlocks: This prevents confusion between the three Rios. The 1992 Earth Summit gave us UNFCCC, CBD, UNCCD. The 2012 Rio+20 gave us PAGE and SDG process. The 1972 Stockholm gave us UNEP.

Worked example: Question: The UNFCCC was adopted at which summit? → Use the mnemonic: UNFCCC is from the second summit, Rio 1992. You can recall “StoRioRio” → first = Stockholm (1972), second = Rio (1992), third = Rio+20 (2012). Answer: Earth Summit 1992.

Additional Memory Aid for MDBs and Nature Hubs

“All Development for Nature” – ADN stands for Asian Development Bank and Nature Solutions Finance Hub. The first two letters of ADB plus “N” for Nature. So whenever you see “Nature Solutions Finance Hub”, think “ADN” → ADB + Nature.
